included in the Uniform Facilities Library (refer to section 1.03, paragraph “E”) are intended as a general
guidelines for design and services. These documents are not intended to replace the work and due diligence
of the design professional and their best judgment, nor is it to be taken verbatim as a contract specification.
The goal is to ensure that all campuses are provided with code compliant, functional, durable buildings and
infrastructure, with consistent materials, finishes and fixtures for efficient maintenance.
Tarrant County College District (TCCD) or its representative(s) will review design work to assure general
compliance with TCCD Design Standards. TCCD will not undertake a detailed technical review of your work.
Reference section 1.09 in this guideline for processes regarding implementation, updates, deviations, and
variances from the Technical Design Guidelines.
As a Design Professional it is your responsibility to ensure code compliance, adherence to all TCCD stan-
dards, completeness, and correctness of the design, cost estimate, and all engineering concepts and details
of the work. This responsibility includes coordination of the various architectural, civil, structural, mechanical,
electrical, and other subdivisions with each other and with the specifications.
TCCD’s review, approval or acceptance of, and payment for the design services shall not be construed as a
waiver of any rights under the design agreement.
If TCCD determines that a design submittal is unacceptable, a resubmittal may be required. During the con-
struction phase of the project, TCCD or their representative(s) may review any project submittals.
If TCCD determines that a construction submittal, or a portion of, is unacceptable, a resubmittal may be
required.

1. Form is submitted to the TCCD Director of Engineering by an Employee of TCCD, member of a
Design Team currently working on a TCCD project, or a General Contractor currently working
on a project. This form would be accepted during the Design Phase only - once a project is in
construction, variance forms will not be accepted. This form currently resides in the TCCD Website
and a sample of it is included in the TDG’s for reference. Please disregard the process description
attached to the form provided in the Website.
2. TCCD Review Committee conducts an internal review – to approve or reject request.
3. Record of the review results is filed internally by TCCD.
4. Notification sent to the Requestor, TCCD Representative for the project, A/E Representative for
the project, and General Contractor Representative for the project. Notification includes copy of
the signed request form with Approval or Rejection stamped. If approved Design team shall be
required to include a copy of the approved variance in the project manual if the project is in the
planning or design phase; if approved during the construction phase the design team shall issue a
copy of the approved variance by ASI or Change Order as applicable.
5. Approved variances shall be kept for internal review by TCCD as a potential permanent change. If
recommended to be a permanent change to the Technical Design Guidelines, a TCCD employee
from the variance review process shall submit a Change Request Form to the Engineering Dept..
E. Change Request Process (used by TCCD for issuing critical changes or changes to the TDG’s)
1. Form is submitted to the TCCD Director of Engineering by a TCCD employee. This form currently
resides in the TCCD Website and a sample of it is included in the TDG’s for reference. Please
disregard the process description attached to the form provided in the Website.
2. TCCD Review Committee conducts an internal review to decide whether this change is to be
implemented in the TDG’s or to be issued as a Critical Inclusion to a current project.
3. Record of the review results is filed internally by TCCD.
4. If the change is to be implemented in the TDG’s, it will be collected and issued in the next
possible semi-annual adenda release. TDG changes will not be released individually. TCCD
typically issues TDG Addendums twice a year. The exact timing for the addendums is to be
determined by TCCD.
5. If the change is a critical item, and the addendum is not ready for release, direction for the
change is sent to Requestor, all relevant TCCD Employees and representatives of design and
construction teams currently working on projects in writting for immediate implementation, until
the addendum is released.
6. Approved Critical Inclusion Canges shall be included in the Technical Design Guidelines as sonn

N. LIFE CYCLE COST ANALYSIS
1. Perform a life cycle cost analysis (LCCA) for identified mechanical equipment and systems to
evaluate the relevant costs associated with system operation and performance over a specified
service life. The LCCA evaluates relevant costs, including design, procurement, installation,
operation, system life, maintenance, repair, replacement, salvage, utility cost escalation, interest
and depreciation, among other factors, over a specified study period to determine the option that
offers the lowest cost over the life of the system in terms of that option’s present value.
2. Perform an LCCA for the identified systems and equipment using a procedure consistent with
ASTM E 917, Standard Practice for Measuring Life-Cycle Costs of Buildings and Building Systems.
Commercially available software may be used for the analysis, including BLCC5 (Building Life
Cycle Cost), a program developed by the Office of Applied Economics at the National Institute of
Standards and Technology. The software is available for download through the U.S. Department
of Energy (DOE) Federal Energy Management Program (FEMP) website at http://www.eere.energy.
gov/femp/program/lifecycle.cfm.
3. Perform the LCCA based on a present value analysis. If using the BLCC5 program, utilize the
End of Year Discounting method with the Constant Dollar Analysis (simplified to omit inflation
influence, as utility cost escalations are accounted for elsewhere in the program).
4. The following inputs and economic parameters are required to complete the LCCA. Current
economic data should be obtained from TCCD to the fullest extent possible prior to evaluation.
Use consistent economic factors throughout LCCA evaluations to avoid disparity between
analyzed alternatives.
TECHNICAL DESIGN GUIDELINES 14711/15/2024[Division 23] HEATING, VENTILATING, AND AIR CONDITIONING
a. REAL DISCOUNT RATE (time value of money).
b. EQUIPMENT/SYSTEM SERVICE DATE: Set the period of analysis to equal the expected life of
the system. Use equipment life data appropriate for the expected usage and system installation.
ASHRAE-Applications Handbook data tabulated in Estimates of Service Lives of Various System
Components may be used for consistency.
5. COST DATA
a. INITIAL CAPITAL COST: Compile a comprehensive and accurate cost estimate of the expected
design, procurement and installation cost for the proposed system or equipment to be evaluated.
Use cost data sources such as R.S. Means Cost Data books (current year) or estimates generated
by a contractor or cost estimator for system cost input. Use consistent cost data sources between
analyzed alternatives.
b. ANNUAL OPERATING COST: Operating costs should be determined based on the electricity,
natural gas and water utility rates provided by TCCD. Apply utility rates to annual system energy
consumption and performance simulations, performed in accordance with ASHRAE 90.1 of this
Standard, to determine the operating costs for each alternative.
c. Use the same operational system profile for evaluation of alternatives.
d. Escalate annual utility rates per TCCD.
e. ANNUAL MAINTENANCE COST: Estimate annualized maintenance costs for each system or
piece of equipment to be evaluated. Use maintenance cost data provided by TCCD or estimate
maintenance costs using the procedure outlined in the Owning and Operating Costs chapter of the
ASHRAE-Applications Handbook.
1) SALVAGE VALUE: Assess salvage or resale value to systems or equipment as appropriate.
2) Omit from the LCCA costs that are not significantly affected by system selections or design
decisions between alternatives.
3) When one analyzed alternative offers an opportunity to avoid Capital Costs by reducing
building or system scope in other areas of design (e.g. one system alternative eliminates the
need for building square footage required by another alternative), reduce the Capital Cost of
that particular alternative by the amount of the avoided capital expense.
4) Cash flows should be simplified to occur at the end of the year for evaluation purposes.
f. In the event any of the required economic data not available through TCCD, use the data provided
in the DOE FEMP Annual Supplement to Handbook 135 (ASHB 135), Energy Price Indices and
Discount Factors for Life-Cycle Cost Analysis.
g. When performance advantages exist that favor one alternative over another (e.g. one system offers
superior comfort, or improved noise performance over another), make adjustments to incorporate
the differences into the LCCA by subtracting the value of the performance improvement from the
corresponding cost of the alternative. Coordinate with TCCD for evaluation of qualitative issues.
h. The system or equipment alternative providing the lowest Life Cycle Cost should be selected as
the best alternative, assuming the proposed alternative is capable of satisfying the design and
operating requirements.
i. Refer to ASTM E 917 and NIST Handbook 135, Life Cycle Costing Manual for the Federal Energy
Management Program, for specific guidance on completing the LCCA.
148 [Division 23] HEATING, VENTILATING, AND AIR CONDITIONING
j. Provide a list of assumptions and inputs to TCCD for review and approval prior to completion
of the Life Cycle Cost Analysis.
k. Provide an LCCA to determine the optimal equipment selections and system alternatives
including but not limited to the mechanical equipment and systems listed below:
1) Optimized chiller selection and piping configurations with respect to performance.
2) Applicability of VFD compressors for selected central plant chillers.

1.03 DEFINITIONS
A. COMMISSIONING: Systematic process whose purpose is to verify and ensure buildings components/
systems perform interactively and that the building systems meet TCCD’s functional needs. This is
152
achieved by reviewing and recording the Owner’s Project Requirements and performance throughout
the design, construction, acceptance and warranty period with written documentation of activities and
system characteristics. The commissioning process encompasses and coordinates the traditionally
separate functions of system documentation, equipment startup, control system checkout and
calibration, testing adjusting and balancing, functional testing procedures and operator/user training.
B. COMMISSIONING COORDINATOR: A representative of TCCD, designated to the Commissioning Team,
who attends commissioning meetings and acts as the responsible central point of contact between
TCCD and the Commissioning Team.
C. COMMISSIONING PLAN: Plan, written by the Commissioning Agent (CxA), outlining the process
verifying that the new systems perform at or above the expected level. The Plan is a detailed
account of the Commissioning activities as they relate to the project. The plan includes a listing
of commissioning team members, phases of the particular project, and each team member’s
commissioning-related responsibilities during each phase, along with the expected deliverables from
each team member. Communication protocols between the members of the team and their respective
company are defined in the Commissioning Plan. As a living document, the plan will be continuously
updated to reflect the evolving process as developed by the commissioning team. The Commissioning
Plan also includes all relevant prefunctional checklists and functional test procedures to be used
during the commissioning of systems.
D. CONTRACTORS TEST REPORT: Contractor tests are defined as any form of startup, adjustment or
calibration performed on individual pieces of equipment as specified within the equipment sections of
the construction documents. The CxA will provide a Test Report Form to be used by the contractor as
a cover sheet to the actual test results, for the documentation of each specified contractors test.
E. DEFICIENCY: An issue that prohibits the successful passing of any step on the functional test
procedure for any equipment/system that is specified in the commissioning scope of the project.
F. BASIS OF DESIGN DOCUMENT: A concise document prepared by the Architect/Engineer (A/E)
containing information necessary to fulfill the Owner’s Project Requirements, including design data,
required operating conditions, assumptions, calculations, code requirements, references and other
data and information as appropriate to fully document the design methodology.
G. OWNER’S PROJECT REQUIREMENTS DOCUMENT: The Owner’s Project Requirements Document is
a concise document prepared by the A/E with input from CxA of record based on their understanding
of the project requirements and TCCD Design Standards. It records in quantitative and verifiable
terms, the performance goals for the systems to be commissioned. The system performance testing
conducted toward the end of the commissioning process ultimately demonstrates that what was
designed and built does meet the criteria defined in the Owner’s Project Requirements Document.
H. FUNCTIONAL PERFORMANCE TEST: Test of dynamic function and operation of equipment and
systems, rather than components, under various modes, such as during low cooling or heating loads,
high loads, component failures, unoccupied, varying outside air temperatures, fire alarm, and power
failure. Systems will be run through control system sequences of operation and components verified
to ensure response as required by sequence of operations.
I. PREFUNCTIONAL CHECKLIST: List of items to inspect and elementary component tests to conduct
TECHNICAL DESIGN GUIDELINES 15311/15/2024[Division 24] COMISSIONING
to verify proper installation of equipment. Prefunctional checklists are primarily static inspections
and procedures to prepare the equipment or system for initial operation including simple testing of
function of component, piece of equipment or system (e.g. measuring voltage imbalance on a three-
phase pump motor of a chiller system). Word “prefunctional” refers to before functional testing.
Prefunctional checklists will augment and be combined with manufacturer’s startup checklist.
J. FUNCTIONAL TEST PROCEDURE: Procedure that confirms each system will perform its specified
functionality. The contractor will perform the functional test. The CxA will direct and witness the final
functional testing. During the functional testing, the installing contractor will sequence the system as
directed and provide the required test equipment.
1.04 GENERAL REQUIREMENTS
A. TCCD will engage the project CxA. Though contracted to TCCD, the commissioning firm is obligated
to work and coordinate with all design professionals, construction managers, contractors, trade
sub-contractors, testing and balancing firms and other project team members to deliver a project

Tarrant County College District Standard Physical Device
Naming - Labeling Conventions for OneIT Infrastructure Group
Preface: The naming convention is based on industry best practices and the experience of the staff. The
key elements that are common in any naming convention is location, device type, and function to the
extent that support staff can quickly identify the impact on the college.
• Location will include campus, building and floor or room depending on the physical structure of
that location.
o For example, Trinity River complex of buildings have both open floor and classroom
designations. There could be a mix of floor number designations and well as floor and
room number designations.
• Device type includes a high-level view of that device.
o For example, physical server, switch, wireless access point, security camera, etc.
• Function is also at the high-level for several reasons including the transient nature of virtual
devices and servers including those applications that are supported by that physical device.
o For example, a physical server may run an application like DNS, DHCP, or Active Directory
on a single device. To use these functions as part of the name would be impractical.
Note: As of this writing (August 2022), Real Estate and Facilities (RE&F) is going through a building
naming standards change. To that extent, this document will be updated as the naming convention is
set. For now, the document will reflect a default value for campus, building and room.
218
Standards are shown for the various physical devices in the tables below.
Examples in the various areas are as follows:
TECHNICAL DESIGN GUIDELINES 21911/15/2024[Division 27] COMMUNICATIONS

and Security Standards inside the Uniform Facilities Library located in the TCCD website under the
Community tab.
1.02 OPERATION AND MAINTENANCE OF ELECTRONIC SAFETY AND SECURITY
A. DESIGN PHILOSOPHY
1. TCCD requires that the security infrastructure and substructure be designed and installed
in accordance with applicable codes and industry standards. Due to the unique physical
characteristics of many TCCD facilities, some technical design solutions are better suited than
others. These guidelines identify which design solutions are appropriate and approved for the
various types of buildings and areas in TCCD facilities.
B. NEW CONSTRUCTION
1. All new TCCD construction projects shall contain a security infrastructure designed and installed
in accordance with the requirements of these guidelines.
C. RENOVATION TO EXISTING STRUCTURES
1. All existing TCCD facilities undergoing renovation or remodeling shall incorporate a security
infrastructure designed and installed in accordance with the requirements of these guidelines as
much as is practical.
D. APPROVAL FOR ALTERNATIVE DESIGN SOLUTIONS
1. This standard identifies specific design solutions that are intended to meet the requirements of
TCCD. Requests to deviate from this standard or any industry standard will be considered on a
case-by-case basis.
E. PROCUREMENT AND INSTALLATION POLICY
1. In large construction projects the security infrastructure procurement and installation will be
part of the general construction contract. A competitive acquisition should still be pursued with
vendors listed by TCCD as approved. Coordination of the procurement and installation of the
security infrastructure with the general contractor and vendors will be a combined effort of the
NCSD, PPD, PD, SIED and VSSD.
F. SECURITY SYSTEM WARRANTY AND CERTIFICATION
1. TCCD requires a warranty on all equipment, material and installation work included in the security
infrastructure of a project of at least one (1) year from project acceptance. In addition, TCCD
requires that 100% of the security infrastructure equipment and material installed be tested and
certified at the designed and intended performance level. The general contractor shall apply for
TECHNICAL DESIGN GUIDELINES 221
and provide a certificate of warranty from all vendors at the time of project acceptance.
G. INSTALLER QUALIFICATIONS
1. Installation contractors must be manufacturer trained and certified resellers. The installation
contractor must be engaged in the normal business of installing security systems, and licensed to
operate in the State of Texas.
1.03 COMMON WORK RESULTS FOR ELECTRONIC SAFETY AND SECURITY
A. GROUNDING AND BONDING FOR ELECTRONIC SAFETY AND SECURITY
1. GROUNDING, BONDING AND ELECTRICAL PROTECTION
a. Per ANSI J-STD 607 and BICSI Standard
B. PATHWAYS FOR ELECTRONIC SAFETY AND SECURITY
1. Surveillance Camera pathway shall be consistent with Division 27- Pathway Requirements.
2. DESIGN CRITERIA FOR INSIDE PLANT CONDUIT
a. Pathway for security cabling shall adhere to BISCI standard from TR to junction box above
each door. ¾” conduit may be used to route cabling from over door junction box to door
elements.
3. DESIGN CRITERIA FOR INSIDE PLANT PULLBOXES
a. Pull boxes used with security conduits in interior locations shall be rated NEMA-1. Pull boxes
used in damp or wet locations such as plumbing chases or outside shall be rated NEMA-3R.
4. CABLE PATHWAYS AND SUPPORT STRUCTURES
a. The Inside Plant (ISP) security substructure are the cable pathways and support structures
necessary for routing security cabling between ERs, and from the ER to the device location.
Some of these methods include:
1) Enclosed conduit system.
2) Open or enclosed cable trays.
3) Routing above a false ceiling using cable supports.
b. 12-24V Security cable pathways may share cable tray with IT cable tray providing a metallic
divider is installed between the cables.
c. The conduit system shall be routed inside ceilings, floors, and walls to the greatest extent
possible. Surface mounted conduit shall be used only when there is no other route to provide
service to the desired location.
d. For the main floor of “slab on grade constructed buildings” conduit will route in walls
and ceilings, not in or under the slab. If this design is not possible, an alternate must be
presented to TCCD.
e. All device locations shall have a minimum 3/4 inch conduit. Increase the conduit size as
222 [Division 28] ELECTRONIC SAFETY AND SECURITY/FIRE SYSTEMS
necessary for the quantity of cables to be installed. Cable fill shall not exceed 40% and plan
on 25% growth.
C. IDENTIFICATION FOR ELECTRONIC SAFETY AND SECURITY
1. SECURITY ADMINISTRATION
a. Administration of the security infrastructure includes documentation of cables, termination
hardware, cross-connection facilities, conduits, other cable pathways, ERs, TRs, and
other security spaces. TCCD shall implement and maintain a system for documenting and
administering the security infrastructure.

designation scheme must be consistent with the scheme in use on the campus where
the work is being performed. The scheme shall be approved by TCCD prior to use.
2) Each individual cable shall be clearly marked on both ends and multi conductor cables
shall have each conductor clearly marked.
2. DRAWINGS
a. Drawings shall be used to illustrate different stages of security infrastructure planning,
installation, and administration.
1) INSTALLATION (CONSTRUCTION) DRAWINGS: Will show the installer how the
infrastructure is to be installed. The quality of the installation can be directly impacted
by the level of detail in the installation drawings and written specifications. Installation
drawings for TCCD projects shall, at a minimum, show device locations, pathway and
routing, configuration of security spaces including backboard and equipment rack
configurations, and wiring details including identifier assignments.
2) AS-BUILT DRAWINGS: Graphically document the installed security infrastructure through
floor plan, elevation, and detail drawings. In many cases, these drawings will differ from
the installation drawings because of changes made during construction and specific site
conditions. In the as-built drawings, the identifiers for major infrastructure components
must be recorded. The pathways, spaces, and wiring portions of the infrastructure
each may have separate drawings if warranted by the complexity of the installation,
or the scale of the drawings. As-built drawings are a vital component of the security
administration system, and must be kept current as additions, deletions, and changes
take place. TCCD requires the installer to provide a complete and accurate set of as-
built drawings.
3. LABELING

PART 3 - EXECUTION
3.01 GENERAL
A. Follow manufacturer’s installation guidelines.
B. All data and voice cabling and terminations and termination hardware shall be TIA/EIA wiring
configuration T568B
C. The length of each individual run of horizontal cable from the administration subsystem
(Telecommunications Room) to the Telecommunication Outlet shall not exceed 270’.
D. The 4 pair UTP cable shall be Underwriter’s Laboratories (UL) listed type CMP.
E. Pay strict attention to the manufacturer’s guidelines on bend radii and maximum pulling tension
during installation. Notice that the recommended minimum bend radius for a cable during installation
is typically greater than the recommended bend radius after the cable is installed. This is to minimize
tension and deformation as the cables pass around corners during installation. The maximum pull-
force guideline for 4-pair horizontal balanced twisted pair cables is 110 N (25 lb).
F. UTP Cabling:
1. Provide a service loop (for re-termination) for horizontal cables. Place at least 12” of service loop
in outlet box.
2. The horizontal distance is the cable length from the mechanical termination of the media at the
horizontal cross-connect in the TR to the telecommunications outlet/connector in the work area.
The maximum horizontal distance shall be 295’, independent of media type. The length of the
cross-connect jumpers and patch cords in the cross-connect facilities, including horizontal cross-
connects, jumpers, and patch cords that connect horizontal cabling with equipment or backbone
cabling, should not exceed 5 m (16’) in length. For each horizontal channel, the total length
allowed for cords in the work area plus patch cords or jumpers plus equipment cables or cords in
the telecommunications room shall not exceed 10 m (33’).
3. Cable and components shall be visually inspected for proper installation. Cable stress, such as
that caused by tension on suspended cable runs and tightly cinched bundles, shall be minimized.
Plenum rated Velcro ties used to bundle cables should be applied loosely to allow the Velcro tie
to slide around the cable bundle. The vector ties should not be cinched so tightly as to deform
the cable sheath. Cable placement should not deform the cable sheath.
4. Minimum bend radius: The minimum bend radius for cable will vary depending on the condition
of the cable during installation (tensile load) and after installation when the cable is at rest (no-
load).
5. The minimum bend radius, under no-load conditions, for 4-pair unshielded twisted-pair (UTP)
cable shall be four times the cable diameter.
6. Copper cable splicing or bridge tapping is unacceptable.
7. Cables should be terminated with connecting hardware of the same category or higher. To
60
maintain the cable geometry, remove the cable sheath only as much as necessary to terminate
the cable pairs on the connecting hardware. The connecting hardware manufacturer’s instructions
for cable sheath strip-back shall be followed. When terminating Category 6 and higher cables, the
cable pair twists shall be maintained to within 13 mm (0.5 in) from the point of termination. For
best performance when terminating cable on connecting hardware, the cable pair twists should be
maintained as close as possible to the point of termination.
8. The Cable Contractor shall install 4-pair Category 6 plenum rated UTP cables from the appropriate
ER or TR to each outlet location as indicated on the telecommunications drawings
• Category 6 Plenum Rated CMP (Color: Blue). General Cable - GENSPEED 6000
Product #7131900.
• Category 6 Plenum Rated CMP (Color: Yellow). General Cable - GENSPEED
6000 Product #7131942.

include but are not limited to installation certification programs provided by BICSI or the ACP
(Association of Cabling Professionals).
4. The test equipment shall comply with the accuracy requirements for level III field testers as
defined in the TIA CAT 6 Document. The tester including the appropriate interface adapter must
meet the specified accuracy requirements. The accuracy requirements for the permanent link test
configuration (baseline accuracy plus adapter contribution) are specified in Table B.2 of Annex B
of the TIA CAT 6 Standard. (Table B.3 in this TIA document specifies the accuracy requirements
for the Channel configuration.)
5. The test plug shall fall within the values specified in E.3.2.2 Modular test plug NEXT loss
requirements of the TIA CAT 6 Standard.
6. The tester shall be within the calibration period recommended by the vendor to achieve the

TECHNICAL DESIGN GUIDELINES 6111/15/2024[Appendix B]
or kinking resulting from coiling and storing of the tester interface adapters. To deliver optimum
accuracy, preference is given to a permanent link interface adapter for the tester that can be
calibrated to extend the reference plane of the Return Loss measurement to the permanent link
interface. The Cabling Contractor shall provide proof that the interface has been calibrated
within the period recommended by the vendor. To ensure that normal handling on the job does
not cause measurable Return Loss change, the adapter cord cable shall not be of twisted-pair
construction.
8. One hundred percent of the installed cabling links must be tested and must pass the
requirements of the standards in this section. Any failing link must be diagnosed and corrected.
The corrective action shall be followed with a new test to prove that the corrected link meets the
performance requirements. The final and passing result of the tests for all links shall be provided
in the test results documentation in accordance with the Test Result Documentation as listed
below.
B. Site Testing, Inspection and Acceptance
1. The Pass or Fail condition for the link-under-test is determined by the results of the required
individual tests. Any Fail or Fail* result yields a Fail for the link-under-test. To achieve an overall
Pass condition, the results for each individual test parameter must Pass or Pass*.
2. A Pass or Fail result for each parameter is determined by comparing the measured values with
the specified test limits for that parameter. The test result of a parameter shall be marked with
an asterisk (*) when the result is closer to the test limit than the accuracy of the field tester. The
field tester manufacturer must provide documentation as an aid to interpret results marked with
asterisks.
3. A representative of the design team shall be invited to witness field testing. The representative
shall be notified of the start date of the testing phase five business days before testing
commences.
4. At the conclusion of field testing, at a time scheduled by the owner’s representative, the owner’s
representative will select a random sample (up to 10%) of the installed links in each wiring
closet. The Cabinge Contractor, under supervision of the owner’s representative, shall test these
randomly selected links and the results are to be stored in accordance with the prescriptions in
Test Result Documentation as listed below.
5. The results obtained shall be compared to the data originally provided by the Cabling Contractor.
If any (one or more) of the sample test reports displays a failure or fail* result, the Cabling
Contractor shall resolve any conditions causing the failed test and under supervision of the
owner’s representative shall repeat 100% of the testing and the cost shall be borne by the Cabling
Contractor.
C. Performance Test Parameters
1. The test parameters for CAT 6 are defined in TIA CAT 6 standard, which refers to the ANSI/TIA
-568-B.2 standard. The test of each link shall contain all the following parameters as detailed
below. To pass the test all measurements (at each frequency in the range from 1 MHz through 250
MHz) must meet or exceed the limit value determined in the above-mentioned standard.

D. Before installing a Verkada system, the network environment needs to support the following protocols
and services:
• DHCP - Cameras receive their IP address and network settings via the DHCP
protocol. They do not support static IP configurations. A DHCP server must
be present on the LAN to provide the cameras with an IP address, default
gateway, subnet mask, and DNS servers.
• DNS - Cameras use the Domain Name System to resolve Verkada URLs to
their associated IP addresses.
• HTTPS - Cameras communicating with the Verkada Command using HTTPS
over TCP port 443.
• NTP - Each camera is hardcoded with well-known NTP servers on the internet.
NTP is used to sync the camera time, so footage timestampsare correct. The
correct time is also required for HTTPS to work.
E. Verkada Technical Support will ask to trouble shoot these services when there is a network issue. The
troubleshooting process can require a packet capture of network traffic to analyze the root cause.
Note: Cable integrity is important to supply PoE and data to a camere. Cable termination,
interconnects, distance, and bends must all be considered.
Power budgeting
Each Camera requires PoE power to function. Make sure your network switch has enough PoE
power to support all the connected cameras at full power draw.
Don’t forget: Cameras use less power during the day. When cameras switch to night mode,
the IR emitters activate to illuminate the scene for better visibility. The IRs increase power draw.
If multiple cameras are connected to the same PoE switch, the PoE draw can increase
significantly at night. If the switch does not have enough power to deliver to all the cameras,
cameras will go offline. A telltale sign of your switch not having enough power is that cameras
will go offline each night around the same time as other cameras on the same switch when
entering night mode.
An easy way to spec. power on a switch is to multiply the number of cameras connected by 30
watts which is the maximum power delivered by PoE+. For example, if you had 10 cameras,
you would need to calculate this:
10 cameras x 30 watts = 300 watt PoE budget on the switch
Note: Full power draw can be found on the datasheet for your camera model. Remember
each switchport should be able to supply the maximum amount of power required by the
camera.

SECTION 28 05 00 – COMMON WORK RESULTS FOR ELECTRONIC SAFETY AND SECURITY
(Designer to modify specification to meet Project requirements – deviations from listed part numbers requires
prior approval from TCCD)
PART 1 - GENERAL
1.01 DESCRIPTION
A. This Section, Requirements for Electronic Safety and Security Installations, applies to all sections of
Division 28.
B. Furnish and install electronic safety and security cabling, systems, equipment and accessories in
accordance with the specifications and drawings. Provide all programming and licenses as required
to integrate new building elements into the existing electronic access control and surveillance
systems.
1.02 REFERENCE STANDARDS
A. Adherence to, and compliance with, the codes and standards referenced, and the TCC unique
requirements and design solutions identified in the manual, is mandatory. Requests to deviate from
the industry standards and design solutions prescribed in these guidelines may be submitted, on a
case-by-case basis, in accordance with the instructions in the Policy and Procedures section of these
guidelines. No deviation from the requirements of the National Electrical Code (NEC) will be allowed.
1.03 CODES, STANDARDS, REFERENCES, AND APPLICABILITY
A. NATIONAL ELECTRICAL CODE, NFPA 70.
1. The National Fire Protection Association has acted as the sponsor of the National Electrical Code
(NEC) since 1911. The original Code was developed in 1897 as a result of the united efforts of
various insurance, electrical, architectural, and allied interests. The purpose of the NEC is the
practical safeguarding of persons and property from hazards arising from the use of electricity.
The NEC provides the minimum code requirements for electrical safety. In security distribution
design, the NEC must be used in concert with the ANSI/EIA/TIA standards identified below, which
are intended to insure the performance of the security infrastructure.
B. ANSI/TIA/EIA STANDARDS
1. The Telecommunications Industry Association/Electronics Industry Association (TIA/EIA)
Electronic Safety and Security - Sample SpecificationsCAPPENDIX
2
engineering standards and publications are designed to serve the public interest through
eliminating misunderstandings between manufacturers and purchasers. The standards facilitate
interchangeability and improvement of products, and assist the purchaser in selecting and
obtaining the proper product for his or her particular need.
C. CABLING STANDARD, ANSI/TIA/EIA-568 (SERIES)
1. The ANSI/TIA/EIA-568-B (series) is the Commercial Building Cabling Standard. This standard
defines a generic security wiring system for commercial buildings that will support a multi-
product, multi-vendor environment. It also provides direction for the design of security cabling
products for commercial enterprise.
a. The purpose of the standard is to enable planning and installation of building wiring with little
knowledge of the security products that subsequently will be installed. Installation of wiring
systems during building construction or renovation is significantly less expensive and less
disruptive than after the building is occupied. TIA/EIA-568-A establishes performance and
technical criteria for various wiring system configurations for interfacing and connecting their
respective elements.
D. PATHWAYS AND SPACES, ANSI/TIA/EIA-569-B (SERIES).
1. The ANSI/EIA/TIA-569-B (series) is the Commercial Building Standard for Pathways and Spaces.
This standard will be followed for all low voltage systems in all TCC buildings. This standard
encompasses security considerations both within and between buildings, and recognizes three
fundamental concepts:
a. Buildings are dynamic. Over the life of a building, or campus, remodeling is more the rule than
the exception. The standard recognizes that changes will take place.
b. Building security systems and media are dynamic. Over the life of a building, or campus, both
security equipment and cabling change dramatically. The standard recognizes this fact by
being as independent as possible from specific vendor equipment and media.
c. Security is more than just locks and cameras. Security also encompasses many building
systems including environmental controls, fire alarms and emergency
d. paging.
e. In order to have a building, or campus, successfully designed, constructed, and provisioned
for security, it is imperative that the security design be incorporated during the preliminary
architectural design phase. To accomplish this, the architect must work closely with the
designated Security & IT staff members. Through the TCC facilities planning and construction
office.
E. E.GROUNDING AND BONDING, ANSI/TIA-607-A (SERIES)
1. The ANSI/TIA-607-A (series) (also known as ANSI J-STD-607-A) is the Commercial Building
Grounding and Bonding Requirements for Security. The National Electrical Code (NEC) provides
grounding, bonding, and electrical protection requirements to ensure life safety. Modern security
systems require an effective grounding infrastructure to insure optimum performance of the wide
variety of electronic security systems that may be used throughout the life of a building. The
TECHNICAL DESIGN GUIDELINES 311/15/2024[Appendix C]
grounding and bonding requirements of this standard are additional technical requirements for
security that are beyond the scope of the NEC. These standards are intended to work in concert
with the cabling topology specified in ANSI/TIA/EIA-568-B, and installed in the pathways and
spaces designed in accordance with ANSI/TIA/EIA-569-B.
F. AMERICANS WITH DISABILITIES ACT (ADA)
1. The Americans with Disabilities Act defines accessible design considerations such as
spacing between equipment, room layouts mounting heights and device and communications
requirements applicable to Electronic Safety and Security designs and installations. It also
contains regulations concerning alarms and signage.
G. OCCUPATIONAL SAFETY & HEALTH ADMINISTRATION (OSHA)
1. Through the Occupational Safety and Health Administration the federal government enforces the
safety aspects of codes and standards that apply to employee working conditions. Guidelines for
good practice when installing electronic safety and security systems are defined in the following
documents:
a. 29CFR1910, Title 29, Labor-Part 1910 OSHA Standards.
1) 29CFR1926, Tit6le 29, Labor-Part 1926 Safety & Health Regulations for Construction.
2) Individual states may have their own occupational safety divisions. Most states or
localities accept certification of electrical products by a national testing laboratory as
evidence that products and materials are safe for use in that jurisdiction.
H. UNDERWRITERS LABORATORIES INC. (UL)
1. In the United States the Authority Having Jurisdiction (AHJ) typically requires UL testing and
certification on electrical equipment. Some of the applicable standards are as shown below:
a. UL 294 (1999) Standard for Access Control System Units. UL 639 (1997) Standard for
Intrusion-Detection Units.
I. THE BICSI ELECTRONIC SAFETY & SECURITY DESIGN REFERENCE MANUAL
1. The Building Industry Consulting Service International, Inc. (BICSI) is an information technology
association whose mission is to provide state-of-the-art information technology and security
knowledge to the industry, resulting in good service to the end user. BICSI develops and
publishes the Electronic Safety and Security Design Reference Manual (ESSDRM). The ESSDRM
is not a code or standard. The ESSDRM is an extensive volume of information on the various
aspects of security systems and security distribution.
a. The ESSDRM provides discussions and examples of various engineering methods and design
solutions that can be selected and employed in order to meet the requirements of the NFPA
and ANSI/TIA/EIA standards. Designers and installers are encouraged to use the ESSDRM as
an engineering tool, within the constraints of the unique requirements of the TCCD Security
Infrastructure Standards.

SECTION 28 05 28 – PATHWAYS FOR ELECTRONIC SAFETY AND SECURITY
(Designer to modify specification to meet Project requirements – deviations from listed part numbers requires
prior approval from TCCD)
PART 1 – GENERAL
1.01 INSIDE PLANT CONDUIT
A. Security conduit must be properly designed and installed. The design and installation practices for
security conduit have some unique requirements beyond those normally seen in standard electrical
conduit. The following items are required to be included in the design and installation of interior
security conduit:
1. Conduits must be designed and installed in the most direct route possible from the security room
to the device location.
2. The maximum length of LAN copper horizontal distribution cable is 90 meters (295 ft) from the
device location to the TR or security room termination point, no exceptions. This applies in
particular to IP based CCTV cameras or IP based card readers. Where this length would be
exceeded the designer will need to add media converters or additional TR’s as required.
3. Security cabling is always installed in a home-run fashion with individual cables running from the
device location all the way to the security room. Splices in horizontal distribution cable are not
allowed.
4. Factory-manufactured sweeps which meet ANSI/TIA569-A bend radius requirements shall be
used for all security conduit. The bend radius of the sweeps must be a minimum of 10- times the
internal conduit diameter. Bending conduit in the field using manual or mechanical methods is not
acceptable. Standard electrical elbows shall not be used. This sweep radius is necessary to insure
that the conduits can accept future cabling. All horizontal conduit will be tested by the conduit
installation contractor with a mandrel to prove compliance with the sweep radius requirements
throughout the conduit run
5. Each security back box shall have an individual conduit routing to the security room, or to the pull
box or pulling point, connecting to a major cable pathway routing to the security room. Box shall
be located in serviceable space. Looping, or “daisy-chaining,” of conduits between outlet boxes is
not allowed.
6. All conduit ends shall have plastic bushings installed before the cable is pulled into the conduit.
7. Conduits will not be run next to hot water lines, steam pipes, or other utilities that may present a
safety hazard or cause a degradation of system performance.
8. Conduits entering the Security Room should be designed and located allowing for the most
flexibility in the routing and racking of cables.
9. Conduits or conduit sleeves entering through the floor of the Security Room shall terminate four
(4) inches above the finished floor.
TECHNICAL DESIGN GUIDELINES 1511/15/2024[Appendix C]
10. All metallic security conduits entering the Security Room, Equipment Room, or Entrance Facility
shall be bonded together, and bonded to the Main Grounding Busbar with a #6 AWG ground
cable.
11. All in-use and spare conduits entering the Security Room, Equipment Room, or Entrance Facility
shall be sealed to prevent the intrusion of water, gasses, and rodents throughout the construction
project. Within five days of releasing the conduit for the installation of cable, the conduit
installation contractor shall prove all conduits to be clean and dry.
12. All conduits and cables that penetrate fire rated walls or floors must be fire stopped.
13. All OSP conduits and inner-duct, used and spare, shall be plugged with watertight plugs at
both ends to prevent the intrusion of water, gasses, and rodents throughout the construction
project. All OSP conduits shall have pull lines rated at a minimum of 90 kg (200 lb) pulling
tension installed. The pull lines must be re-pulled each time an additional cable is installed. Prior
to releasing the conduit for the installation of cables, all OSP conduits must be cleaned with
a brush pulled through the conduit at least two times in the same direction and swabbed with
clean rags until the rag comes out of the conduit clean and dry. All OSP conduits must be tested
with a mandrel to prove compliance with the sweep radius requirements throughout the conduit
run. Within five days of releasing the conduit for the installation of cable, the conduit installation
contractor shall prove all conduits to be clean and dry.
16
PART 2 - PRODUCTS
2.01 INSIDE PLANT PULLBOXES
A. Pull boxes used with security conduits in interior locations shall be rated NEMA-1. Pull boxes used in
damp or wet locations such as plumbing chases or out of doors shall be rated NEMA-3R. Pull boxes
shall be installed in conduits at an interval no greater than every 100 feet. A pull box shall be installed
in conduit runs whenever there are two 90°sweeps, or a total of 180°of sweeps, in a conduit run. Any
deviations from these criteria must have prior approval from TCCD Facilities Construction.
2.02 CABLE PATHWAYS AND SUPPORT STRUCTURES
A. The Inside Plant (ISP) security substructure are the cable pathways and support structures necessary
for routing security cabling between security rooms, and from the security room to the device location.
There are numerous different products and methods that can be employed to build the substructure.
Some of these methods include: Enclosed conduit system, Open or enclosed cable trays, Routing
above a false ceiling using cable supports, and in-slab floor ducts. Security cable pathways shall
be separate from IT pathways whenever and where ever possible, if it is necessary to route security
cabling in the same cable pathway as IT cables a metallic divider must be installed between the
cables.
1. The conduit system shall be routed inside ceilings, floors, and walls to the greatest extent
possible. Surface mounted conduit shall be used only when there is no other route to provide
service to the desired location.
2. For the main floor in, “slab on grade constructed buildings”, conduit will route in walls and
ceilings not in or under the slab. If this design is not possible, an alternate must be presented and
approved following the “Approval for Alternate Design Solutions” process detailed in section 27
01 00. If an under slab route solution is approved, the conduit must be installed with at least 1” of
concrete encasement around all sides of the conduit.
3. All device locations shall have a minimum ¾” conduit. Increase the conduit size as necessary for
the quantity of cables to be installed. Cable fill shall not exceed 40% and plan on 25% growth.
4. Security cable and conduit shall maintain the minimum separation distance from power as listed
below.
5. For power systems operating at 480V or greater, maintain a minimum separation distance of 3 m
(10 ft) from all security cabling. Pathways should cross perpendicular to electrical power cables or
conduits.
6. For large electrical motors or transformers, maintain a minimum separation distance of 1.2 m (4 ft)
from all security cabling
7. For lightning protection system conductors (NEC 800-13), maintain a minimum separation
distance of 1.8 m (6 ft) from all security cabling
8. For power systems operating at less than 480V, including all conduit and cables used for
TECHNICAL DESIGN GUIDELINES 1711/15/2024[Appendix C]
electrical power distribution, maintain a minimum separation distance of 0.6 m (2 ft) from all
security cabling. Pathways should cross perpendicular to electrical power cables or conduits.
9. For fluorescent lighting, maintain a minimum separation distance of 12 cm (5 in) from all security
cabling. Pathways should cross at right angles to fluorescent lighting.
10. For branch circuits (secondary) power (120/240V, 20A) where electric light or power circuits
coexist with security cabling, maintain a minimum separation distance of 0.50 mm (2 in).

prior approval from TCCD)
PART 1 GENERAL
1.01 SECURITY ADMINISTRATION
A. Administration of the security infrastructure includes documentation of cables, termination hardware,
cross- connection facilities, conduits, other cable pathways, security rooms, and other security
spaces. All TCC facilities shall apply and maintain a system for documenting and administering the
security infrastructure.
1. In order to create a consistent environment, TCC maintains a campus wide numbering scheme
for security devices and cable connectivity.
a. All security devices and cables shall be clearly marked using permanent means. The
designation scheme must be consistent with the scheme in use on the campus where the
work is being performed. The scheme shall be approved by TCC Facilities & IT prior to use.
1) Each individual cable shall be clearly marked on both ends.
2) Multi conductor cables shall have each conductor clearly marked
1.02 RECORDS
A. A record is a collection of information about or related to a specific element of the security
infrastructure. Records must be maintained in a computer spreadsheet, or in a computer database.
Paper records are encouraged, but are optional. A cable record is prepared for each cable. The
record will show the cable name, and must describe the origin point and destination point of the
cable. The cable record will record what services and/or connections are assigned to each conductor
or strand. An equipment record is prepared for services distributed from a certain piece of equipment,
such as a router, or a system such as data gathering panel.
1.03 DRAWINGS
A. Drawings are used to illustrate different stages of security infrastructure planning, installation, and
administration.
B. Installation or Construction Drawings
1. Installation or construction drawings are the plans that show the installer how the infrastructure
is to be installed. The quality of the installation can be directly impacted by the level of detail in
the installation drawings and written specifications. Installation drawings for TCC projects shall,
at a minimum, show pathway locations and routing, configuration of security spaces including
backboard and equipment rack configurations, and wiring details including identifier assignments.
C. As-built Drawings
20
1. The as-built drawings graphically document the installed security infrastructure through floor plan,
elevation, and detail drawings. In many cases, these drawings will differ from the installation
2. drawings because of changes made during construction and specific site conditions. In the
as-built drawings, the identifiers for major infrastructure components must be recorded. The
pathways, spaces, and wiring portions of the infrastructure each may have separate drawings if
warranted by the complexity of the installation, or the scale of the drawings. As-built drawings are
a vital component of the security administration system, and must be kept current as adds, moves,
and changes take place. TCC requires the installer to provide a complete and accurate set of as-
built drawings.
1.04 LABELING
A. To be consistent with ANSI/TIA standards and industry practices, it is important that labeling be
applied to all security infrastructure components. Labeling with the unique identifier will identify a
particular component.
B. Labels are generally of either the adhesive or insert type. All labels must be legible, resistant to
defacement, and maintain adhesion to the application surface.
1. Outside plant labels shall be totally waterproof, even when submerged.
2. All labels shall be machine printed.
3. Labels applied directly to a cable shall have a clear vinyl wrapping applied over the label and
around the cable to permanently affix the label.
4. Other types of labels, such as tie-on labels, may be used. However, the label must be appropriate
for the environment in which it is used, and must be used in the manner intended by the

1.0 -Introduction to TCCD BIM Standards
1.1 TCCD BIM Standard Mission Statement The mission of the Facilities Department at Tarrant County College District is to successfully integrate district facilities. In delivering the mission, the Facilities Department’s number one goal is to provide for a safe, healthy and comfortable building environment for TCCD employees and the many thousands of students and visitors in TCCD buildings daily. By adhering to the below outlined BIM Standards it allows TCCD to develop and maintain graphic and related information which users can manage, operate, maintain and improve the facilities, grounds, and related infrastructure systems of TCCD.
1.2 Overview In general, the TCCD Building Information Model (BIM) Standards shall be followed by all Consultants engaged by TCCD to provide a Project’s design in BIM. This Standard describes the processes, procedures, and requirements that shall be followed for the preparation and submission of BIM(s) for TCCD Projects (new building and additions), as well as to produce, release, and receive data in a consistent format so to maintain an efficient exchange of data between disciplines and the compatibility of each disciplines’ Model(s). In order to achieve this goal, TCCD has chosen to utilize several “Autodesk” products. Therefore, terminology and references that are unique to the “Autodesk” based software applications are utilized throughout these Standards.
1.3 Design Although a Building Information Model that facilitates the design process and analysis of a Project will be the Design Team’s building block for the development of Contract Documents (Drawings), at this time a Building Information Model is not intended for construction purposes. 1.The Building Information Model shall be referred to throughout the design phase and construction phase of a Project as a Design Intent Building Information Model. 2.In order to ensure that portions of the Contract Documents (Drawings) that are derived from a Design Intent Building Information Model are correct, all Extracted Drawings shall contain the necessary Level of Development (LOD); data and information required for the development of the Contract Documents (Drawings) and required analyses. 3.Being that the Design Intent Building Information Model is not meant for construction purposes, it shall not be made a part of the Contract Documents.

1.4 Construction As indicated above, the Design Intent Building Information Model is not meant for construction purposes. In addition, it is not meant to imply means and methods of construction, and will not be made part of the Contract Documents. However, the Design Intent Building Information Model may be shared by TCCD with a contractor that is awarded a contract for the construction of a project for their convenience so that they may, if they so elect, utilize the Design Intent Building Information Model to develop a Building Information Model of their own, which they may choose to use for:
Estimating
Fabrication
Construction Sequencing
Scheduling Analysis Trade Coordination
Etc. Although it shall be understood by all parties that the Contract Documents are complete, the contractor will be required to agree that the Design Intent Building Information Model, which may be shared by TCCD with the contractor for their convenience, is not complete and shall not be relied upon by a contractor for the execution of the work.
1.5 Close-out/ As-Built Documents As-Built Models are Design Intent Models that have been updated throughout the construction process. These changes and updates have been communicated from the contractor to the Design Team through the comments, annotations, and mark-ups from the As-Built Documents. These typically, but not always, are discipline specific models. For all BIM projects, As-Built models following below outlined TCCD BIM Standards for each discipline must be submitted by the contractor. Contractors are to produce and submit a COBie (Construction Operations Building Information Exchange) spreadsheet that records installed equipment data (see COBie section of the Standards for more detailed requirements). All contractor As-Built deliverables will be submitted to TCCD for review and approval prior to the submittal of the contractor's final payment application. If review of the preliminary As-Built drawings/BIM(s) reveals errors and/or omissions, the drawings/BIM(s) will be returned to the contractor for corrections. The contractor shall make all corrections and return the drawings to TCCD within ten (10) calendar days of receipt. If more than two reviews are required, TCCD will be compensated by the contractor.
1.6 Contractor’s Use of Digital Data All BIM(s) and other BIM related electronic files and data that are to be provided for the convenience of a contractor shall always be through TCCD and shall never be directly between the consultant and a contractor and/or sub-contractor. TCCD will only provide a
Design Intent Building Information Model and BIM related electronic files and data to a contractor after the contractor has requested such, in writing, from and as required by TCCD.

When a BIM Model and/or other BIM related electronic files and data are requested by a contractor from TCCD and TCCD agrees to provide the model, the contractor shall be required to sign a “Terms of Electronic File Transfer” document that has been prepared by TCCD, which amongst other things, establishes as fact that the BIM(s) and other BIM electronic files are not intended as an end product and do not constitute a part of the Contract Documents, see Appendix E. In light of the fact that BIM(s) and other BIM related electronic files are not to be relied upon by a contractor and are not part of a set of Contract Documents: 1.The Design Team shall not respond to any questions specifically related to the content within a BIM Model or other BIM related electronic files from any entity that pertains to the execution of the work described within a set of Contract Documents, which are the basis of a contract between TCCD and a contractor. 2.Notwithstanding the above, the Design Team shall respond to any and all questions, from TCCD, which pertain to the services required by these guidelines and Standards.
1.7 Ownership The consultant and its sub-consultants shall assign to TCCD all of their rights, title and interest, including all copyrights, copyright registrations, copyright applications, renewals, extensions and all other proprietary or ownership rights, in all Drawings and Building Information Models. This includes, but shall not be limited to, information, electronic files, data provided by TCCD, “Revit” Families (system-based and/or component-based) and any other content submitted as part of the BIM Model. All of the above shall become the property of TCCD at the conclusion of the Project, or termination of the services of the consultant, whichever is earlier, and when requested by TCCD in writing shall be delivered to the TCCD clearly marked, identified, and in good order.
1.8 Model Requirements All BIM(s) shall be developed in accordance with the most current version of TCCD BIM Standards and shall be compatible with the current version of the BIM application currently in use by the TCCD at the time an agreement had been reached and agreed upon, in writing, between the consultant and TCCD. In addition, all Models shall be provided to TCCD as per the latest version of Autodesk Revit software.
1.9 Versioning of the Standard The BIM Standard will be reviewed, and updated where deemed necessary, as a planned annual effort. Updates to individual modules, or new sections, may be issued at any time when significant changes are needed. The BIM Standards Manual will clearly reflect the revision number and date within the footer of each section.

1.10 Printed Copies Uncontrolled Printed Copies of this manual and sections are “uncontrolled” as noted in the footer of each page of the BIM Standards Manual, meaning there is no attempt made to systematically update printed version of the standard. The online BIM Standards Manual found on the TCCD Website is considered the “official” version and should be used to avoid potential reference to out-of-date printed copies.
1.11 BIM Standards Orientation & Training BCAD will provide staff training and on-going support regarding the development, maintenance and implementation of TCCD BIM standards as needed. Should you or any of your team members require such training and support, contact your project manager for further direction.
1.12 Note to the Consulting Firms TCCD consultant contracts and design guidelines may reference this document. Each of the following sections contains the most essential criteria for developing Building Information Models (BIM’s). Refer to “Consultant Deliverables” section for specific requirements. Refer questions to the Facilities Department at TCCD.
1.13 Note to Users These Standards are to be followed by TCCD Revit users as well as all outside consultants providing Revit Models to TCCD. The BIM Standards will be reviewed annually. Recommendations will be considered during the review. BIM Standard deviations will only be accepted in project models with prior approval of TCCD.
1.14 Basis of TCCD BIM Standard The TCCD BIM Standards are based on the U.S. National BIM Standards (NBIMS-US™ V3) version 3 and National CAD Standards (NCS), Version 6. Modifications and refinements have been made to align these BIM Standards with TCCD’s facility documentation needs. In instances where there are differences between the TCCD BIM Standard and the NBIMS-US, the TCCD BIM Standard shall control. For items not covered in the TCCD BIM Standard, refer to the NBIMS-US for general guidance and consult with your BIM manager. TCCD encourages employees and consultants to refer to the NBIMS-US as an additional resource. TCCD BIM Standards has also referenced additional standards published by:
New York City School Construction Authority
General Services Administration
The American Institute of Architects
AEC (UK) BIM Technology Protocol
Australia & New Zealand Revit Standards
Army Corps of Engineers

1.15 Definitions The TCCD BIM Standards generally follow NBIMS-US and Autodesk terminology, some of which may not be familiar to all Revit users. This will be especially true of the terms used to describe different categories of electronic files used in creating Revit Models. Please refer to NBIMS-US, your BIM manager, or the Autodesk Help page for any definitions as needed.
1.16 Is this a Revit Standard? Yes, since Revit is the primary Building Information Modeling (BIM) platform of TCCD, the BIM Standards Manual is written in this context. In that sense, the Manual will refer to settings in Revit and uses the “language” of Revit. This Standard will also reference additional tools or software to be used in conjunction with Revit. Those include, but are not limited to:
COBie Toolkit
Navisworks Manage
Excel
Etc.

2.0 -Consultant Deliverables
2.1Overview TCCD’s goal with these Standards is to create Facility Drawings and Models that are consistent in appearance and which integrate the required flexibility to meet the fluid and expanding needs of TCCD. We believe these standards are comprehensive and practical … and we invite our consultants to utilize them in their entirety. It is however, not TCCD’s intention to add undue burden on the consultants with these standards. TCCD understands their consultants may have spent considerable effort and expense in developing their own in-house standards and production methods. In defining the “Consultant Deliverables”, TCCD has attempted a compromise … one that provides TCCD with the structure and flexibility needed with the drawings and models, yet still allows the consultant to maintain most of their production methods.

3.0 -Process & Quality of Deliverables
3.1 BIM Implementation Plan The information contained within these Standards is the basis for the implementation of Building Information Management design by TCCD. The implementation of policies and protocols not provided by TCCD for the implementation of a successful design through Building Information Modeling, such as, but not limited to; Electronic Communication Protocols, BIM Information/Data Exchange, Permission Files and the roles, responsibilities and staffing requirements for each member of the Design Team, is the responsibility of the consultant.
3.2 Model Quality In addition to adhering to TCCD Standards, each member of the Design Team shall establish their own modeling quality control guidelines and exchange protocols. Good BIM practices include, but are not limited to:
The Use of elements and component objects that embed the best practices of the firm
The Maintenance of parametric linkages within the model at all times
In the absence of TCCD Standards, use Industry Standard nomenclature for objects and spaces
Use appropriate and interoperable viewing, checking, and output file formats TCCD requires that all Revit Models shall be developed using object-based elements only, such as columns, beams, walls, doors, windows, etc. along with their associated parametric information. This will stream down the Revit processes from design all the way down to construction and then operations. It is essential that the Design Team tailor its “Quality Control Program”, which is required by the TCCD Architectural and Engineering Contract for Consultant Services, to ensure the overall quality of the Contract Documents and BIM Model(s). The required BIM “Quality Control Program” shall, at a minimum, include the following checks to ensure quality:
Collaboration Procedures o Ensure coordination, communication and exchange protocols
Visual Check
o Ensure that there are no unintended model components
Interference Check
o Detect conflicts in the model and/or models where building elements are clashing
Standards Check o Ensure that TCCD BIM Standards have been followed (fonts, dimensions, etc.)
Element Validation Check
o Ensure that the data set has no undefined or incorrectly defined elements

The Design Team is encouraged to use electronic project collaboration tools such as document management and file sharing sites, reviewing tools, project communication websites, web meetings, and videoconferencing.
3.3 Quality Assessment Report Upon completion of the Services required, TCCD will perform an assessment of a project’s BIM/Revit Model(s) so that it may assess the Design Team’s compliance with the TCCD’s BIM Standards and the effectiveness of the Design Team’s required “Quality Control Program”. The focus of the TCCD’s “Quality Assessment Report” will include, but will not be limited to, the following:
Section 1
Required models have been provided, including appropriate level of detail and content of models.
Schedules are populated from models
Interferences and conflicts (clashes) between building elements have been mitigated
Section 2
Compliance with technical criteria
Adherence to predetermined standards (See section 2 “Consultant Deliverables” for a detailed list of consultant requirements)
Proper utilization of parametric data exchange between disciplines Upon the TCCD’s completion of a BIM/Revit Model’s quality assessment, TCCD will provide the Design Team with a copy of the “Quality Assessment Report” for appropriate action which shall include, but not be limited to, bringing a project’s BIM/Revit Model(s) into full compliance with the TCCD’s BIM Standards.
3.4 Contract Document Quality As described previously, the Design Intent Building Information Model will not be made part of the Contract Documents. The Contract Documents (Drawings) shall be the 2-dimensional (2-D) Drawings. 1.The aforementioned 2-D Drawings shall be the basis for the bid and award of a contract for the execution of the Work. 2.Unless specified otherwise herein, all required Drawings, including, but not limited to; plans, details, sections, elevations, schedules, diagrams, as described by the TCCD “Design & Construction Standards”, shall be provided in 2-D and the level of development and information provided shall be sufficient for the execution of the work.

4.0 –Building Information Models (BIM)
4.1 General BIM(s) are required for all Phases of design and certain Building Elements/Systems are required to be modeled for the successful execution of a Design Intent BIM Model. 1.Section 3.3 identifies Models that are required, at a minimum, for Architectural, Structural, HVAC Systems, Electrical Systems; and Plumbing/Drainage and Fire Protection Systems. a.In order to facilitate the development of Building Elements that need to be modeled, the TCCD has developed a library of standard TCCD Families for the use of Architects and Engineers that are preparing Contract Documents (Drawings) for the TCCD. b.The Design Team shall use Building Elements that are provided by TCCD. c.The Design Team may use modeled Building Elements that are not available in the TCCD Standard Library of BIM Families such as those that are provided by Content Provider’s (i.e.: “Revit”), Manufacturers and/or created by the Design Team, provided that the amount of data and/or parameters of such models do not incorporate unnecessary information, data and/or graphics.
4.2 Level of Development/Model Content The Model Level of Development describes the degree to which the element’s geometry and attached information has been thought through – the degree to which project team members may rely on the information when using the model. The Level of Development is accumulative and should progress from Level to Level. 1.At a minimum, all required Models shall be detailed to the Level of Development required by each Design Phase and/or Sub-Phase. 2.BIM(s) shall be created that include all geometry, physical characteristics, information and data necessary so to describe and facilitate the design, intended construction, and cost estimating of a project as necessary to meet the requirements, as described herein, for each Design Phase and/or Sub-Phase of a project. In addition, all drawings, simulations, and services required for analysis, and review shall be extractions from the Model(s). 3.Required Modeled Building Elements need not illustrate/depict individual parts that are required for the assembly and/or the manufacture of the Modeled Building Element. The intent of a required Modeled Building Element is to provide overall size, shape, clearances, information, data, and the orientation of a Modeled Building Element for its installation and coordination with other required work, as well as for the population of required Schedules. 4.Although Building Elements that may be found in the TCCD Standard Library of BIM Families shall be used when required by the following Levels of Development, the Design Team may elect to use these Building Element Models when a model is required, at a level of lesser detail, during any Design Phase and/or Sub-Phase.
D16

5.The following “Level of Development Key” shall be followed by the Design Team when providing Models for the different phases. Note that the following images illustrate the expected amount of graphical information to comply with the indicated level of development, with a wall slab-assembly used as an example. The tables illustrate the amount of data/information to be included if one were to extract a schedule or perform an analysis at the indicated level of development. 6.When in doubt, users should opt for less 3D geometry, rather than more, as the efficiency of the BIM is largely defined by the performance of the components contained within.
LOD 100: LOD 100 elements are not geometric representations. Examples are information attached to other model elements or symbols showing the existence of a component but not its shape, size, or precise location. Any information derived from LOD 100 elements must be considered approximate. Example: Solid mass model representing overall building volume; or, schematic wall elements that are not distinguishable by type or material. Assembly depth/thickness and locations are still flexible.
LOD 200: The Model Element is graphically represented within the Model as a generic system, object, or assembly with approximate quantities, size, shape, location, and orientation. Non-graphic information may also be attached to the Model Element. At this LOD elements are generic placeholders. They may be recognizable as the components they represent, or they may be volumes for space reservation. Any information derived from LOD 200 elements must be considered approximate. Example: Generic wall objects separated by type of material (e.g. brick wall vs. terracotta). Approximate overall wall thickness represented by a single assembly. Layouts and locations still flexible

LOD 300: The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of quantity, size, shape, location, and orientation. Non-graphic information may also be attached to the Model Element. The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension call-outs. Example: Composite model assembly with specific overall thickness that accounts for veneer, structure, insulation, air space, and interior skin specified for the wall system. (Refer to LOD350 and LOD400 for individually modeled elements) Penetrations are modeled to nominal dimensions for major wall openings such as windows, doors, and large mechanical elements. Required non-graphic information associated with model elements includes: Wall Types, Materials
LOD 350: The Model Element is graphically represented within the Model as a specific system, object, or assembly in terms of quantity, size, shape, location, orientation, and interfaces with other building systems. Non-graphic information may also be attached to the Model Element. Parts necessary for coordination of the element with nearby or attached elements are modeled. These parts will include such items as supports and connections. The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension call-outs. Example: Cold formed metal framing is developed with sufficient elements to support detailed interface coordination with other systems such as MEP. Image notes: 1.Elements in red are critical wall support elements that cannot be easily cut for coordination of MEP opening through the walls. 2.Diagonal bracing (kickers) that may be in the above ceiling space are modeled for coordination with other building content such as MEP passing along the wall in the above ceiling spaces. 3.Infill cold formed metal framing modeling (Orange) may be omitted at this LOD if deemed so but the project team. Cladding and sheathing are not shown for clarity in this image.

LOD 400: The Model Element is graphically represented within the Model as a specific system, object or assembly in terms of size, shape, location, quantity, and orientation with detailing, fabrication, assembly, and installation information. Non-graphic information may also be attached to the Model Element. An LOD 400 element is modeled at sufficient detail and accuracy for fabrication of the represented component. The quantity, size, shape, location, and orientation of the element as designed can be measured directly from the model without referring to non-modeled information such as notes or dimension call-outs. Example: Cold formed metal framing is developed with sufficient elements that support the fabrication of the CFMF system. Image notes: 1.Connection content is development in the wall elements. This includes but is not limited to fasteners, clips, and other related hardware.
LOD 500: The Model Element is a field verified representation in terms of size, shape, location, quantity, and orientation. Non-graphic information may also be attached to the Model Elements. This model can be field modified LOD 300, 350, or 400 model.

Pre-Schematic Design Intent Models Upon the conclusion of the Bidding and Award Phase, the Consultant shall ensure that all Addenda to the Contract Documents (Drawings) that affect the Design Intent BIM Model(s) are incorporated into the Design Intent BIM Model(s) before they are provided to TCCD for its information and use. 1.The Design Intent BIM Model(s) shall not be combined into a Composite Model, but instead remain as distinct Component Models, as provided by each member of the Design Team. 2.The Consultant shall ensure that all Models, which are affected by Addenda to the Drawings, have been quality controlled, coordinated and executed as per these BIM Standards. 3.Upon receipt of written notification from TCCD, the Consultant shall submit electronic files, to TCCD within twenty-one (21) calendar days.
4.4 Coordination & Clash Detection Upon receipt of TCCD’s written notification of acceptance of the Design Phase - Contract Documents (100% Contract Documents), the consultant shall submit an electronic copy of the required Coordination/Clash Detection Report (“Navisworks”) to TCCD with the final submission of Contract Documents for bid and award. All conflicts and interferences identified within the Model and/or Models, which would adversely affect the Work described within the Contract Documents (Drawings), shall be rectified prior to the final submission of Contract Documents to TCCD for bid and award. 1.At a minimum, the Design Team shall use automated conflict checking software (“Navisworks”) to identify coordination issues within and between the Models that would adversely affect the execution of the Work required by the Contract Documents (Drawings) during and at the conclusion of Design Phase - Contract Documents (100%). 2.The Design Team shall, at a minimum, use the “Interference Check Tool” within “Revit” on a routine basis during and at the conclusion of each Design Phase and/or Sub-Phase, and as per their approved “Quality Control Program.”
NOTE: At this time, TCCD understands that the 3-D modeling of certain building elements (e.g.: multiple horizontal pipes and conduits that for coordination purposes would be vertically stacked) does not facilitate TCCD’s need for the printing of Contract Documents in 2-D. Hence, coordination conflicts and interferences created by the need to organize models to facilitate 2-D printing will be accepted within models provided that each conflict and/or interference that has been created within a model, to facilitate 2-D printing, is appropriately noted and documented within the required Coordination/Clash Detection Report (“Navisworks”) that is to be submitted to TCCD. TCCD does not dictate a specific “Clash Detection Reporting” format, therefore consultants can utilize their own reporting format, as long as the information is organized and presented in a logical and easy to follow manner.

5.8View Titles To establish TCCD brand and unified look of drawing set produced by the different consultants, TCCD requires that all consultants as well as in-house design teams use TCCD issued drawing titles. Drawing titles are set up in such way that allows for a total of (3) line titles. This option is controlled via viewport types. In order for the drawing titles to function properly, custom parameters are created for the drawing title entries
5.9Room Tag Every space in TCCD facilities will have a room identifying tag on the drawings. TCCD-G-ANNO-ROOM-TAG family has been designed in such way as to capture critical information that TCCD staff needs to manage. All applicable fields of both visible and invisible parameters must be filled in for every room. For MEP Projects, consultants will use identical Space Tag.
While consultants are encouraged to use TCCD Room tags, they are not required to. As long as the custom parameters established by TCCD are associated with each room/ space and properly filled out, consultants can use their own room tags. Consultant room tags however, must match TCCD Font styles. Space type definition is controlled and to be filled out based on the definitions listed in the Appendix H.

5.10 Schedules Typical Schedules are developed and placed in TCCD Revit templates. These schedules reflect general guidelines issued by the National CAD Standards. See Appendix J for some Typical Schedules. TCCD in-house design teams will use TCCD developed schedules in their projects. For general schedules such as Door, Window, Plumbing Fixtures, etc. consultants can use their own in-house developed schedules to best convey project design intent. TCCD has created a few schedules that apply to standard TCCD Room Schedule. These schedules are there for the purposes of TCCD facility master drawings and models. Even if consultants choose not to use those schedules, they MUST be present in ALL models. These schedules include:
*Occupancy Loads - IBC 2012 o Schedule of keys based on the IBC-2012 table 1004.1.1 Maximum Floor Area Allowances per Occupant (see Appendix K).
*Occupancy Schedule
o A working schedule which tracks space square footages, calculates allowable occupancy based on the occupancy type, and lists space use as per Texas Higher Education Coordinating Board Space Use Codes
*Space Use Code Table
o Schedule of keys as per Texas Higher Education Coordinating Board Space Use Codes (see Appendix H).
ROOM SCHEDULE o Schedule which is reporting a summary of the working *Occupancy Schedule. This schedule is placed on facility master drawing and used to track facility specific use and occupancy data. o Consultants MUST leave this schedule fully populated in their models and MUST NOT modify it in any way. o If a different room schedule is needed to properly convey project design intent, consultants can create additional Room Schedules as needed.
SHEET INDEX
o Organized for all trades and will only display Record Drawings sheets (will be used after completion of the project and is not to be altered by the consultants)
5.11 TCCD Standard Family Library There are a number of additional typical families developed for the use in TCCD drawings for all trades. This library will be continually evolved so please request updated library before starting a new project. Refer to Appendix I for the additional family definitions.

6.1 Options
General Note to Consultants:
These user-interface and file access settings are
for TCCD in-house design teams. Consultants
can choose to follow below outlines settings or
they can use their own in-house CUI settings. To make the required modifications, go to the APPLICATION menu and select the Options button. This will open the OPTIONS Dialog Box as shown in following images. Select the General option and make the necessary changes as shown in the image to the right. Unlike AutoCAD, the Revit-based applications do not have an auto-save feature. The “Notifications” settings will only remind users to save the local and central versions of their 3D Models. It is critical that user saves as often as possible. The “Username” should match your PC “login name” or your Autodesk Subscription Center user name and should never be changed. Worksets rights are set upon this value.
NOTE: Changing the username in the middle of the project will break the synchronization established between the Central File and the Local File, restricting the user’s access to the Worksets and increasing the chances of corrupting the Project.
File Locations Select the File Locations tab and verify that under the “Default Template File” the discipline-specific template is selected; that under the “Default Path for User Files” the appropriate

All TCCD workstations should be configured to access these files as indicated. If it is different than described here, please contact your BIM Manager.
NOTE: Consultants should copy these files to the appropriate directories. Contact your System Administrator or CAD/BIM Manager for proper use.
6.2 Templates All Revit projects must be created using one of the templates provided with the TCCD Revit Standards, which are:
TCCD General Template_2016.rte
TCCD Architectural Template_2016.rte
TCCD Structural Template_2016.rte
TCCD Electrical Template_2016.rte
TCCD Mechanical and Plumbing Template_2016.rte To promote consistency in the Contract Set as well as to prevent the use of un-licensed fonts, all TCCD Text Styles, Dimension Styles, Leaders, Tags and Content have been defined using the Arial family fonts. All of the template settings and TCCD Modeling requirements are described in more detail below.
6.3 Model Categories For the purposes of establishing unit and precision settings, model types are broken into three categories as follows:
Category Types of Work Included Survey Land Surveys, Plats, Property Deeds Site Work Civil, Landscape, and Site Utilities drawings for wholly site related documentation Building Architectural, Structural, and MEP&F drawings Within TCCD Facility Models all three types may be employed. For example, TCCD South Campus might have grounds topographical model, site utilities models, and building models. The building models may include architectural, structural, mechanical, plumbing, and fire protection as-built conditions models.

6.4 Units & Precision Imperial units are the standard system of measurement for TCCD models unless S.I. (International System of Units) units are specified by the reviewing agency, or an industry standard for the type of work being performed.
NOTE: Rounding Precision only affects how Revit displays object properties and measurements (not dimensions). See the 6.11 Dimension Styles section for guidance on dimensioning unit settings, which are distinct from drawing unit settings. For discipline specific units setting see discipline specific Revit Architecture, Revit Structure, and/or Revit MEP sections in this document.
6.5 Precision Settings Model “Length Precision” settings are not intended to establish or imply a required degree of field or construction precision. For example, four decimals of precision (0.000) for a site utilities drawing does not indicate that three decimals of utilities placement as-built information accuracy is expected or required. Dimensioning precision is completely independent of drawing precision. Dimensioning precision, unlike drawing precision, is

generally related to the expected degree of construction precision, which will be discussed in 6.11 Dimension Styles section.
6.6 Drawing Origin
Project Base Point Draw building model so that the lower left intersection of the outermost column/building lines that remain constant on most floors are placed at 0, 0, 0 – Revit Project Base Point. This ensures that all projects follow the "2 Mile Rule," where any elements modeled must be within a one-mile radius (2-mile diameter) of this point. In order to ensure the proper insertion of Revit Links and the stacking of floor plans, the origin point for an entire building or site must be consistent between models. Once the origin is established, it should not be changed. Architectural model should define the coordinates and the rest of the models liked into the architectural model (i.e. structural, MEP, etc.) will acquire shared coordinates from the Architectural model.
Note to TCCD Consultants: Drawing Origin point at the lower left intersection of the outermost column/building lines is established for TCCD Master Facility model management purposes and will remain consistent. Consultants CAN use campus wide project base point established by the civil engineer for the duration of the project. At the final project closeout stage, however, consultants are required to relocate project to the base point as described above.
Relocating Project Base Point If your model or someone else’s model was created with improperly located Project Base Point, that point can be relocated:
To turn on the visibility of the Project Base Point and
Survey Point in a view: Click VIEW tab Graphics panel (Visibility/Graphics). On the Model Categories tab of the VISIBILITY/GRAPHICS dialog, scroll down to “Site”, and expand it. To display the project base point survey point, select Project Base
Point and Survey Point.

6.7 Text Settings The use of Arial family fonts for the TCCD standard has been selected. Follow these rules when using these fonts:
Use a width factor of 0.8 (except for Arial Narrow) on all text styles, but most importantly in general notes, tags, and dimensions.
To get italics, apply italics option in the text editor as needed, NOT in the Font Style.
To accentuate items of critical importance, use bold option in the text editor, NOT in the Font Style. Underline in the text editor can also be used.
Some additional text and label styles were defined to be used within TCCD standard families and parameters. If you have any questions regarding the use of these text and label styles, contact your CAD/BIM manager.
6.8 Leaders All callout type annotation shall be made using the TCCD text and label styles with appropriate leader settings described below. Rules of good drafting, such as having the same length for all lines of text whenever possible and not crossing leader lines, should be followed on all drawings. Both right and left justified text can be used in the drawings, with left justified being preferred. Regardless, the left justification or right justification should be consistent on the entire drawing set. Key settings are listed below:
Text – Revit text, ALL CAPS, Arial, at 3/32” text height (Use TCCD_Standard text style).
Justification – Right/top justify if leader on right and left/top justify if leader on left (see example below).
Leader – There should be ½ text height (1/64”) between text and landing line of leader as this also defines text border. The leader line should always be straight, not splines (area callout is the exception).
Terminator – Size shall be 3/32”. The default terminator type is a Filled Arrow 20 Degree. However, other terminator types are discussed in the subsection titled “Leader Terminator Types”.

To modify Revit Arrowhead settings go to MANAGE Ribbon Tab and expand ADDITIONAL SETTINGS pull-down menu.
Leader Terminator Types It is important for the drawings to convey information in a clear, consistent, and effective manner. To accomplish that, TCCD standard requires the use of different leader terminations when calling out objects on the drawings. The standard terminator types are described and pictured here:
Arrow Filled 20 Degree – This is the most common type of arrowhead and should be used for pointing to a general location of an object, such as top of wall. End of arrowhead should touch the object.
Open Dot – Use this type for identifying a small object such as rebar in section view (in fact, this will almost exclusively apply to rebar).
Filled Dot – Use this type for adding notes to the dimension string.
None – Use this type for pointing to a particular location on an object such as a box highlighting a section that is detailed elsewhere or calling attention to a revision cloud with a note.
Diagonal – Use this type for pointing to an object or region but not a specific location on the object or region.
Loop – Use this type for identifying conduits, pipes, horizontal rebar, etc.
Elevation Target – Use this type for identifying elevation points where tag may not be a suitable option (e.g. top of wall, grade spot elevation, etc).

Modifying placed text/ leaders are subject to the following rules:
Do not modify TCCD Text Type definitions.
When using tags, follow same Leader guidelines as described above. -Room Tag will use Filled Dot Leader Terminator
Additional settings for Transparent or Boxed Text types can be created as needed.
6.9 Text Orientation Text and dimension text should always read left to right and bottom to top. When text is oriented at an angle between horizontal and vertical the following guide should be used in determining text orientation. Notice as text approaches vertical orientation, as in the top left and bottom right quadrants below; it is read top to bottom.
6.10 Dimensioning Use associative dimensioning whenever possible.
Never force or override dimensions (do not manually enter 10’-6” as a dimension if the drafted distance is actually 10’-6 ½”). o The exception to this might be a detail that was not drawn to scale. In this case the dimension would read NTS.
Dimension precision is independent of drawing precision, which is covered in the Units and Precision module.
6.11 Dimension Styles The overall objective with dimensioning is for all dimensions of a similar type to have a uniform appearance in terms of arrowheads or ticks, offsets, text height, and other dimension settings. To accomplish this objective, TCCD has developed common dimension types to achieve dimensioning consistency throughout all drawings. TCCD dimensions should be used for all dimensioning. Revit dimension types are provided for decimal, architectural, and fractional formats:
Modifying placed dimensions are subject to the following rules:
Do not modify TCCD Dimension Type definitions.
Additional settings for Transparent or Boxed Text types can be created as needed.
See Appendix B for complete list of the dimension type settings.

Dimension Style Use by Drawing Category As described in the Units and Precision module, drawings are broken into three categories; Building, Site Work, and Survey. For Building work, which encompasses Architectural, Structural, and MEP drawings, dimension styles with “Inch” units and “Tick” terminators should be used. For Survey and Site work drawings, dimension styles with “Feet” units and
“Arrow” terminators should be used.

These parameters will be continuously reviewed and added to. To differentiate between Revit system, TCCD custom, and consultant added parameters, the below outlined convention should be followed:
Revit system parameters – Capitalize Each Word (Default and generated by Revit) o E.g. Discipline, Door Swing, Wall Finish…
TCCD custom parameters – ALL UPPER CASE LETTERS (included in the TCCD Revit Templates as well as in the TCCD_Shared Parameters.txt file)
o E.g. CAMPUS, DESCRIPTION, ISSUE DATE…

Consultant parameters – Prefix with Consultant Company name (Abbreviated), underscore and ALL UPPER CASE LETTERS for the parameter name.
o A single parameters .txt file will be included and submitted with the model.
o Name .txt file as: XYZ_Shared Parameters.txt (Where XYZ is abbreviated consultant company name)
o E.g. XYZ_CAMPUS, XYZ_DESCRIPTION, XYZ_ISSUE DATE…
NOTES:
The Autodesk Revit Products can reference only one shared parameter file at a time, so make sure this is the default file when working on TCCD projects.
See Appendix G for a list of TCCD Parameters and their setting.
6.18 Worksharing When the project size and complexity necessitates, TCCD encourages the use of Work Sharing and Central Models. Work Sharing allows for multiple team members to work on the same model simultaneously. Each discipline’s Central File folder has a series of standardized sub-folders that will contain various groups of design data. The image to the right illustrates the Central File standardized sub-folders using the Architectural Folder as an example. The Central File will be saved on the Discipline’s “0 – Model” Folder. Backup folder is generated by Revit automatically and should NOT be renamed, moved, or deleted under any circumstances for any “Living Model”.

Whenever possible, a decision to make a model a workshared model should be made BEFORE a model is started. You cannot initiate worksharing/worksets in a template file. Once a new project has been started from a template worksharing may be enabled. It is critical that all of the elements placed in the model are assigned to the correct workset. Worksets will be established based on the project needs and will be the responsibility of the Project and/or BIM Manager. Suggestions for common workset organizational principles:
Revit Links - make a workset or worksets to contain Revit links so that the project can be opened more easily using the selective open tool. You may want a link for Structure, MEP, and Site, for example.
AutoCAD Links – create worksets to contain AutoCAD links so that the project can be opened more easily using the selective open tool.
Shell vs Core - in larger projects this can provide a logical way of making the project more manageable.
Furniture - NIC objects like furniture might also be a good candidate for a separate workset. Keeping the central file healthy is critical to keeping the project running smoothly and to avoid causing file corruption. Below are the best practices that need to be done routinely on the central file to keep it clean. How often is going to depend on how active the project is. The more active the project is, the more often it should be maintained.

1.Open the Central File, clearing the option to create a Local File and enabling the option to Audit the file. 2.Avoid using in-place families or detail groups. Use families or detail components whenever possible as in-place families and detail groups are damaging to the model, especially when they are repeated throughout the model. 3.Use the Purge Unused tool from the MANAGE tab, Settings panel of the ribbon to remove any unused and unnecessary content from the file. Be careful not to remove content simply because it is unused; make sure that the content you are purging is not needed. In particular, look for in-place Families and Group definitions that are no longer being referenced. 4.Save the Central File using the option to “Compact the Central File” as shown in Figure below:
5.Specify the maximum number of backups to keep on disk. Be careful setting this number too small, as you will be limiting the number of file versions to choose from in the event that you need to recover a corrupt project. 6.Once the new Central File has been saved, users will need to create new Local Files. Always create a new Local File whenever the project is opened for editing (append a time stamp to an existing Local File). Creating new Local Files as frequently as possible is a good way to manage file size and maintain stability. 7.Ensure that all user-created worksets and borrowed elements are relinquished before saving. 8.It is recommended (especially on large projects) that an entire Central Model is re-created periodically by detaching the file from central (preserving all worksets) and re-saving it as a new central file (you can override the old one).

6.19 Naming Convention All electronic project information should be named following the TCCD BIM Standards naming conventions.
Folder Naming Convention If sub-folders are needed, they can be created under the predefined Project Folder Structure and they should follow the Folder Naming Convention. The folders should be named beginning with a four-digit year, a two-digit month, and a two-digit day followed by an optional User Description. The folder should take the form of:
File Naming Convention – Central Files All electronic files should be named following the File Naming Convention, including Revit files (RVT), Plotsheet files (DWF), Revit Family files (RFA), AutoCAD files (DWG), Image files (JPG), Animation files (AVI), Microsoft Office files(DOC, XLS, HTML), NavisWorks files (NWF, NWC), and Analysis files (multiple formats). Revit is unique as compared to AutoCAD drawings set, in the sense that both Model and Sheet views are in the same file. Therefore Revit Model naming convention will be similar to that of an AutoCAD Sheet Set Naming Convention.
Facility Master Models:
Examples: SACT-ARCH-MASTER-CENTRAL-2016.rvt SACT-HVAC-MASTER-2016.rvt * “CENTRAL” should only be appended to work shared models.
All Other Projects:
Examples: 20028-ALLT-TRTR_MATH_EMPORIUM-2016.rvt 20154-FIRE-PANEL_UPGRADES-CENTRAL-2016.rvt * Only an underscore (_) character may be used when word separation is desired in “Description” field. Do not use dashes (-) or spaces.

Local Files The Local File should be a copy of the Central File, which is done through the Revit application, and should be named with the prefix per above followed by the user name. As the Central File, once defined, the Local File name shall not change through the life of the project. After saving the Local File, Revit creates a folder named “YOUR FILE NAME_backup”. Neither this folder nor the files contained within it should be moved, renamed, or deleted.
Revit Family Files Family files should be named beginning with the Functional Type followed by the Subtype, the Manufacturer Name, and two optional User Description fields. The filename should take the form of:
Capitalize the leading letters in each portion of the family name.
Keep file names as short as possible because they need to display in the Type Selector.
Do not use spaces between words in the file names. To separate words, use the underscore “_” character.
Create a Type Catalog for Family files that contain five or more types. Refer to Section below - Type Catalog Convention.
Examples:
Window-Double_Hung-Andersen-400_Series_Archtop-2016.rfa
AHU-Vertical_Packaged-Sierra-Roof_Top-2016.rfa
Framing-Wood-Lumber-2016.rfa
Foundation-Concrete-Rectangular-2016.rfa
Family Types Types within a Family file should indicate the key differences or variations between the different Family options. Depending on the Family Component, the Type names might take one of the following forms: <Model> or <Series Number> <Value> or <Capacity> <Width>x<Depth>x<Height>
Do not include the Family Name in the Type Name.
Type Names should mirror actual usage.
Capitalize the leading letters in each portion of the Type Name (when applicable).
When Types are named by size, use dimensions only.

Type Catalog Convention Create a Type Catalog for Family files that contain five or more types or when the Family file exceeds 500 KB of memory. Name the Type Catalog file (.TXT) with the same name as the Family file (.RFA) that it supports.
If a Type Catalog is used, no predefined Types should exist in the Family file.
Do not include the Family Name in the Type Name.
Type Names should mirror actual usage.
Capitalize the leading letters in each portion of the Type Name (when applicable).
When Types are named by size, use dimensions only.

Sheet Naming Convention Following the cover sheet, sheets should be organized into subsets as per below image:
TCCD Sheet numbering Syntax follows NCS recommendations with some modification for the Facility Master Drawings and includes the following components:
The discipline designator, consisting of one alphabetical character and a hyphen or two alphabetical characters and a hyphen.
The sheet type designator, consisting of one numerical character.
The sheet sequence number, consisting of two numerical characters. Sheet numbering refers to the sheet designation labeled in a specified spot within the title block that uniquely identifies the sheet. Sheets are drawings that are part of the contract document set and the sheet number is therefore quite important for organizing the drawing set and for referencing between drawings. An example of sheet numbering is shown below.

The syntax for assigning sheet numbers is shown below: Examples:
A-102 – Architectural Plan, Second Floor
A-105 – Fifth Floor Architectural Master Plan
S-220 – Structural Framing elevations
P-602 – Plumbing Riser Diagrams Note the cover sheet does not have a Discipline Designator, or Sheet Type Designator. The sheet number is simply “Cover.” Each section of the Sheet Numbering Syntax, specifically Discipline Designator and Sheet Sequence Designator are explained in the sub-sections below.
Discipline Designator The Discipline Designator creates the primary “sort order” of the drawing set. Sheets are grouped by discipline and disciplines are ordered in a logical fashion, according to NCS.

LEVEL 1 DISCIPLINE DESIGNATOR
Discipline Designator Table in order of drawing set, rather than alphabetical: The primary organizer of drawing sets is disciplines. The order that the disciplines appear in the drawing set generally follows the order in which a project is built, starting with site related disciplines (geotechnical, civil, landscape, hazardous materials, etc.), then to overall building/facility related disciplines (architectural, structural, interiors), then to building/facility systems (mechanical, electrical, plumbing, etc.), and finally to construction and maintenance with shop drawings and operations.
Sheet Type Designator The Sheet Type Designator is a single digit that indicates the “type” of information presented on the sheet such as plan, elevation, schedule, etc. If multiple types of information are presented on a sheet, select the dominant one from this table. The practice of putting multiple information types on a sheet is encouraged to avoid creating a separate sheet for a minimal amount of information.

Mixed Sheet Types It is common for elements of sheets to be of mixed “Sheet Types.” For example, details or elevations are often included as part of plan sheets. This is perfectly acceptable as long as:
The primary element of the sheet controls the Sheet Type Designator.
The sheet title in the title block is descriptive enough to indicate the nature of the drawing, such as “Storm Drainage Plan and Details” for storm drainage plans that includes details.
Sheet Sequence Designator Because of the wide variety of projects within TCCD, the practice of using the Sheet Sequence Designator is thoroughly controlled by the standard. Sheet Number Blocking – For large facility drawing sets such as those for TCCD, it is useful to do Sheet Number Blocking, which may be defined as using the Sheet Sequence Designator to block out ranges for different types of drawings within a Sheet Type. A master floor plan example is grouping Plans (Sheet Type 1) by designating that sheet numbers in the range A-100 to A-109 are reserved for existing condition plans, A-110 to A-
A-102 (uses a “Plan” sheet type designator)

119 are reserved for reflected ceiling plans, sheet numbers in the range A-120 to A-129 are reserved for finish plans, etc. Gaps in Sheet Sequence Number – Using the above approach to group types of sheets will create gaps between sheet sequence numbers. However, if TCCD standard is properly followed, there should be very few sheets that need renumbering when sheets are added or deleted. This is critical because most revision comments are based on sheet number. It is not necessary to designate sheet numbers as “Not Used” on the cover sheet. As long as all used sheets are listed on the cover sheet, the order of the plan set should be obvious. 00 vs. 01 – The use of Sheet Sequence Designator ending in zero (0), such as A-100, A-110, A-120 etc. should be reserved for cases where a general or overall sheet, like a key plan or notes, precedes a series of other sheets. A master plan example is an Overall Campus Plan (A-110) preceding 5 sheets that are separate building plans on that campus (A-111 to A-115). Otherwise, 01 should be the first Sheet Sequence Designator.
Sheet Set Sequencing Sheet sets are ordered first by the Discipline Designator (see the Discipline Designator table for order) and then by the three digit number that is composed of the Sheet Type Designator and Sheet Sequence Designator. When sheets are placed in numerical order, this numbering system will group sheets by Sheet Type such as Cover Sheet, General, Plans, Elevations, Sections, etc. The Discipline Designator Table is taken directly from NCS (with the exception of "U" for Site Utilities and “K” for Space Tracking) and lays out the order that discipline specific drawings should fall within a plan set.
Sheet Index Lists BIM designers and technicians must recognize that projects have team members without access to Revit, but who routinely review, utilize, and/or provide design input to sheets in the project sheet set. It is considered a “best practice” to maintain a sheet list outside of the Revit environment that reflects the sheets for all disciplines (existing and planned) in the Revit environment. This is the function of the Master Sheet Index (MSI). All facility drawings as well as new projects with contract drawings are advised to maintain a Master Sheet Index (MSI) that is stored under the “3 – Misc” folder of the project folder. The filename should be G-SH-MSHT_INDEX.xlsx. In the case of multiple or distinct final packages, the description field of the filename can be modified to reflect the respective package. The MSI should be maintained by the project team member responsible for the BIM(s) on the project (project BIM coordinator). Master Sheet List should be generated for each BIM Model and that list can be then exported to TXT and XLS formats to stream line the process and avoid errors between the two lists.

7.0 -Revit Architecture Standard
7.1General This Section of the TCCD BIM Standards for consultants establishes the criteria for some common architectural elements in the models.
7.2 Walls
Naming Convention Considering that projects might contain a variety of walls with many layers, a standard wall type naming convention and tags are established by TCCD. This will allow for a controlled type name length and user friendly sorting in the type selector for an efficient selection and modeling. Some standard material abbreviations have been defined below, but additional ones can be created based on the individual project needs.
Note: A larger table is included in the Appendix D for your reference.

Display Settings For a proper wall display for both electronic file and printed sheets, walls should have the following line weight setting assigned (this should be done globally under the MANAGE tab, Setting Panel, Object Styles dialog box):
Facility Models (Record Models) generated based on the field surveys will be displayed using coarse setting indicating walls as two lines of a specified thickness. In some cases, where known, masonry wall may display coarse hatch indicating the materials. Most of the existing conditions models will be generated using generic wall styles.
Fire Rated Walls Fire rated walls will be designated within the wall styles and named appropriately as per above wall naming convention. Here shown patterns will be assigned to display in plan views as needed. These patterns will apply to all fire rated walls in the model. Pattern can be assigned as either or both – as a Custom Material Definition as well as a Coarse Scale Fill Pattern. This will ensure that the fire rated walls are visible and easily identifiable for all trades.

7.3 Doors For a proper door display for both electronic file and printed sheets, doors should have the following line weight setting assigned (this should be done globally under the MANAGE tab, Setting Panel, Object Styles dialog box):
In addition, door frames will not be displayed in Facility Master Models.
7.4 Plans and Elevations TCCD encourages both outside consultants as well in-house design teams to prepare models and drawings that “speak” and convey the design intent in a clear and easy to interpret manner. Methods such as using solid/ halftone patterns to highlight columns or bearing structural walls, assigning shadows to the elevations, employing a variety of line styles and line weight, even using color as needed. Designers should be aware of software limitations, however, such as having to use raster processing for shadows thus reducing the line work quality. Any of the methods used should be carefully considered and only adopted if it improves the presentation and documentation of the design intent.
7.5Space Use Plans All of TCCD existing buildings as well as new projects will have a Revit model. TCCD will use these models throughout the lifetime of the building as a facility management tool. Each facility master model will have a color coded Space Use Plan generated. This plan is generated in accordance with the Texas Higher Education Coordinating Board Space Use Codes (see Appendix H). A Schedule of Keys listing appropriate Space Use Codes as well as the Definitions has been generated and will be included with TCCD template. Consultants are not required to generate such plan, but they are require to fill in the appropriate Room parameters Based on the information provided in the Appendix H.

8.2Systems Categories in Revit tend to be very general and do not distinguish between similar objects made of different material or that have different uses. For example, Revit doesn’t graphically distinguish between a pipe used for domestic cold water and one used for liquid refrigerant without the use of Systems. Therefore, Systems are being provided within the Mechanical and Plumbing Templates to address this issue. Systems have been defined within TCCD Templates for objects such as ducts and pipes and will address the issue described above for the following sub-disciplines:
Mechanical Equipment
HVAC
Plumbing
Fire Protection All TTCD Systems have been associated to work with the View Templates, therefore different systems will show different colors once the View Templates are applied.

10.0 -COBie/Commissioning
10.1 General Guidelines TCCD has adopted COBie as the methodology to electronically transfer building information after construction is complete for facilities management. The COBie spreadsheet is part of the U.S. National Building Information Model Standard (NBIMS). Third-party utilities facilitate the automatic creation and transfer of some data between BIM and a COBie spreadsheet via IFC files as an intermediate stage, and some BIM software may include creation of and data transfer to the spreadsheet directly without making use of intermediate IFC files. Where possible, automatic means should be used to create and fill in the COBie spreadsheet. While the actual methodology used by individual consultants is up to the consultants, TCCD strongly recommends using COBie Extension for Revit available for download on Autodesk’s web site.
The Consultant Team shall inquire with their BIM software vendor(s) for the most current COBie utilities. However, the completed COBie worksheets will also contain some information that is entered manually into the electric file, either because the information currently cannot be conveniently extracted from the BIM or because it does not reside in the BIM (i.e. team contact information, zone assignment to spaces, etc.) The design/construction team is encouraged to provide as much information in COBie as is known at the time of the deliverable.
The consultant team(s) shall submit the most current version of the COBie spreadsheet with other required deliverables at each project phase.
With CD deliverables, the COBie Type and Component worksheets are required. These fields provide component name, description, and creation date.

11.0 -Electronic File Management
11.1 Overview An AutoCAD or Revit file is an electronic file that represents one or more sheets in the project drawing set (sheet files), “component" drawings, or data files (model files, schedule files, details files) that are referenced into the sheet files. TCCD file structure is organized to facilitate proper management of the Master Facility Drawings and keep them separated from the on-going projects. Later described workflow allows for efficient updates to facility master drawings based on any completed projects. Folder structure screen shots shown throughout this section indicate the standard file management practices, but do not show an entire folder structure.
0 – Master Facility Drawings This is where the Master Facility drawings and models will be stored. Drawings and Models will be in a read only format (write-protected) and used as a reference and for information reporting purposes.
1 – Current Projects – In-House Contains active projects generated at TCCD by TCCD design team.
2 – Current Projects – Consultants Contains active projects generated by the outside consultant teams.
3 – Completed Projects – Add To Masters Contains complete project close-out documentation, including final as-built drawings and models, generated by either TCCD in-house teams or outside consultants; that are to be incorporated into the Master Facility Drawings and databased for archival information.
4 – Record Drawings Contains all of the existing drawings TCCD has for all facilities and sites in DWG, PDF, TIFF, JPG and other formats. These files are databased and searchable. They should only be used as historical reference documents.

11.2 Sheet Files Sheet File is the NCS term for the electronic files that represent the sheets that will be printed as part of your project drawing set, or contract drawings. In AutoCAD, Sheet Files generally include a sheet border in paper space, various paper space symbols and annotations, and typically include viewports to drawing information in model space where drawing objects and one or more model files may reside. For Revit projects, PDF and native file formats of the most current sheets shall be maintained in this folder and organized with sheet file naming outlined in File Naming and Numbering of the Standards.
Creating Subfolders under Sheet Files As a general rule, subfolders should only be created to segregate drawings by discipline as is shown above. For Current Projects, the discipline subfolders can be omitted if project size and scope does not warrant discipline subfolders.
11.3 Model Files The “2 – Model Files” folder includes all file types used to assemble the sheet files that make up the project drawing set. Primarily it will consist of Revit Models, any AutoCAD links, Image Links, Tables, etc. All files in the “2 – Model Files” folder should be current files. Do not "clutter" the “2 – Model Files” folder with different versions of files as this ultimately leads to confusion and errors. For work shared models, “1 – Central Files” folder will be created.
Creating Subfolders under Model Files As a general rule, subfolders should only be created to segregate drawings by discipline as is shown above. For Current Projects, the discipline subfolders can be omitted if project size and scope does not warrant discipline subfolders.

Campus o Building
Sheet Files

Misc. Files All of the Drawings in the Facility Master Drawings directory will be for reference and reporting only.
NO new design work should ever be done on these files. Only after projects are complete and a set of final as-built drawings and models have been provided to TCCD, TCCD Facilities Department staff will incorporate the latest information into the Facility master drawings and models.

Survey All of the projects being developed by TCCD in-house design, construction, and maintenance teams will be stored in this folder for the duration of the project. “Sheet Files”, “Model Files”, and “Misc.” folders will serve the same purpose and follow same standards as described in the preceding sections 10.2 through 10.4.
Projects Projects folder naming convention will follow currently established e-Builder format.
e-Builder automatically assigns project number and the Project Manager will assign the project name.
Conceptual The Conceptual folder is intended as the storage location for model files and sheet files that only pertain to the conceptual phase of a project. The file naming convention is the same as the model and sheet files described in this standard. Subfolders may be created as needed. Serious consideration, as well as data validation should be taken before copying any conceptual data into the “Model Files” folder for use in design.

Publish When drawings are published, such as to a printer/plotter “hardcopy” or DWF/PDF/PLT “digital” format, they represent the status of the drawing at the time they are published, essentially creating a picture or snapshot in time of a drawing. The published drawing loses continuity with the active drawing immediately after it is published as it has no ability to keep pace with the changes in the drawings, until the next time it is published. To the design team, the value has a short time span, but to the client or a reviewing agency, it is valuable because it is a snapshot at a particular milestone on a project. To that end, the Publish folder is intended as a temporary holding location for published drawings and BIM(s) in a DWF, DWG, IFC or PDF format. The published drawings either proceed to the printer/plotter for “hardcopy” distribution or to the Deliverables folder as part of a “digital” deliverable package to the client. In either case, the Publish folder should be cleared of all files after the project is complete.
Support Files Support files are all the files that are created and saved over the course of a project that neither get submitted to a client nor referenced to a file. This folder is also to store data as it is being assembled for use in the “Model Files”, “Sheet Files”, and “Misc” folders (the folders containing the drawings that make up the project drawing set). Use of this folder will prevent two things that often affect project BIM work from occurring:
It will keep the "production folders" (Model Files, Sheet Files, and Misc) clear of multiple versions and "junk" files, which often lead to confusion and misuse of files.
It provides a specific location to store temporary files so they are not stored on local drives or in other network folders. When folders and files in the “Support Files” folder are no longer needed, they should be deleted.
Survey The Survey folders contain Field Survey related files generated by TCCD staff and/ or outside consultants. This folder will contain documents such as field surveys for any trade, civil/ site survey information, raw point clouds generated via 3D scanner, photos, etc. Users can generate sub-folders as needed to organize different types of field information, but should use logical and easy to follow names (such as “Photos”, “Point Clouds”, “Field Notes”, etc.)

11.7 Current Projects – Consultant Projects developed by outside consultants will follow the same file storage format as the in-house projects. Any documentation received from the consultants will be placed in an appropriate folder for the project duration. Final close-out documents will be databased, incorporated into the Master Drawings and moved to the Record Drawings folder. It is the responsibility of TCCD consultants to turn over their project documentation in an appropriate format and file organization.
11.8 Completed Projects – Add To Masters This is a temporary file storage location for recently complete projects. It contains complete project close-out documentation, including final as-built drawings, generated by either TCCD in-house teams or outside consultants. Once the complete project information is incorporated into the Master Facility Drawings and the rest of the documents are databased, the entire project MUST be moved to the “4 – Record Drawings” folder. Maintenance of this folder should take place bi-annually.
11.9 Record Drawings Contains all of the existing drawings and models TCCD has for all facilities and sites in DWG, RVT, NWC, PDF, TIFF, JPG and other formats. These files have been sorted for duplicates, organized, databased and indexed to be searchable based on a number of project parameters. They should only be used as a historical reference document and are in a “Read-Only” format.

The project CAD/BIM lead is responsible for occasionally auditing the CAD/BIM folders to ensure that this standard is being followed and that good file management practice is being employed. A few things to keep in mind: •Keep folders free of “junk”, “old”, or “erase me” files.
The “Model Files” folder and the “Sheet Files” folder should only contain current files that can be reliably used on the project. There should be no confusion as to file "versioning" because multiple versions should not exist in these folders. Use the “Support Files” folder as described herein for versioning, assembly and "experimenting", and short term archiving.
All drawings/ models shall be purged of empty, unused, or non-essential drawing data.

12.0 -BIM File Transmission
12.1 Definition of BIM Files Electronic BIM Files, herein simply referred to as “BIM files” are defined as Revit, Navisworks, IFC, DWG, PDF and any other BIM application files.
12.2 Distribution of BIM Files 1.Unless electronic BIM file distribution is explicitly defined by the contract, no BIM files may be distributed to outside parties unless the policy defined herein is followed. 2.All electronic file transfers shall include a copy of the standard TCCD Terms of Electronic File Transfer (TEFT) with the transmittal. This is available on the TCCD web page (see Appendix E for a standard TEFT Form). 3.When sending the files by email or notifying the recipient of a download site by email include the TEFT at the bottom of the email or as an attachment in PDF format. 4.The electronic files should be prepared by transmittal such that all necessary data files, font files, plot settings, x-refs, links, etc. are included and appropriately structured. The transmittal should include adequate documentation to explain the contents of the electronic files. The standard policy for preparation of electronic documents for transmittal is to utilize the “win-zip” feature.

13.0 -Plotting & Plot File Management
13.1 Plot File Definitions and Categories When the term "plot file" is used herein, it refers to the file that is created from a model file (.RVT, .DWF, PDF, etc.) that will be sent to a plotter to produce a paper copy of the drawing file. The following three (3) categories of plot files are defined for the purposes of describing the standards for creating, naming, and organizing plot files: 1.Check Plots - are run for BIM operator review, informal review or for other team members. Check plots are not associated with a formal milestone review or review submittal. 2.Milestone Review Plots - are run for established project milestones or internal review prior to project milestones. Project milestones include review milestones but not the final deliverable and are typically submitted to clients, client representatives, or review agencies. Milestone review plots are often submitted to obtain permits or approvals. 3.Final Deliverable Plots - are run for submittal of final drawings to clients, client representatives, or review agencies. Final Deliverables include: a.Bid Sets b.Construction Sets c.Supplemental Drawings d.Record Drawings
Plot File Formats The most common types of plot files are Design Web Format (DWF) and Portable Document Format (PDF) files. The TCCD standard is to produce plot files in PDF format whenever possible. While the requirements for naming and storing the two categories of plot files described above differ, all should be produced in the same plot file format as the final deliverable will be plotted in (preferably PDF) to ensure that drawings plotted for review are consistent with final deliverables.
13.2 Plot File Naming and Management All plot files, whether used for checking a drawing/set or a deliverable drawing/set, shall be kept in the "Publish" folder. The individual plot files shall match the name of the plotted drawing. For deliverable sets, a merged single-page PDF version of the sets shall be created and moved under the
D98

Rev. 01 – April 1, 2016
Printed Copies Uncontrolled 97
"Deliverables" folder. This way the project team has access to the package, as delivered, and no duplicate plot files exist under the “Publish” folder. The relationship between the “Publish” folder and the “Deliverables” folder is illustrated in the preceding image.
13.3 Plotting In order to produce consistent plots, the selections shown below should be made when plotting sheet files.
Print Dialog Setting • Printer – use any (i.e. Bluebeam, Acrobat) PDF generator as a default. • File – select the option of
“Combine multiple selected
views/sheets into a single file” as default. Unless specifically requested to generate individual PDF files for each sheet. • Print Range – Will vary based on the user needs.
Print Setup dialog Settings • Name – Name Print setup options based on the sheet size and other distinctive identifiers (i.e. color).
Paper – Varies based on the project/ sheet needs.
Hidden Line Views – choose vector processing by default, unless rendering and color images are being printed, then use Rater processing.
Colors – Choose Black Lines by default, unless rendering and color images are being printed, then use Rater processing.
Other settings – match settings as shown in the image on the right.

14.0 -Archiving & Recovery Management
14.1 General For any archiving or archive retrieval needs contact Al Clark - Assistant Director Records Management/Construction AEC Repository at TCCD. For any lost file recovery and backup file retrieval needs for stand-alone Revit Models contact the Network Administrator at TCCD. Perform the following steps to recover a Central (work shared) Revit Model: For workshared projects, Revit automatically creates a backup folder. This folder should NOT be moved, renamed, or deleted UNDER ANY CIRCUMSTANCES while the project is active and functioning properly.
If Central model recovery is needed, do the following: 1.Copy the backup folder to a location without the central file (this step is critical to prevent the corruption in the project from stopping the recovery). 2.Start Revit 3.Open the software, from the ribbon go to the COLLABORATE tab then to Restore Backup. 4.Revit will ask you whether to recover the .rvt file from the backups. Click “Yes”. 5.Navigate to where the central file is stored. You will see a folder with the central files name_backup. 6.Click once on the backup folder then click the Open button. 7.You will now get a list of times when the backup was saved periodically throughout the day. 8.Click “Save As” and navigate to a location to save the recovered file, and verify you are able to open it successfully. If you are not, you may need to go through steps 1-7 to find an older saved backup file. If you cannot find a backup copy that will open you will need to gather this information and send it into your Support:
A copy of the project file and any linked file(s).
Journal files from each of the machines accessing the project. If possible, send three days worth of data prior to the issue. See the following link for information on how to obtain journal files:

15.2 TCCD Master Facility Drawing/ Model Update Process TCCD will hold the latest Master Facility Drawings and Models (will be referred to as Master Documents in this section) based on the Electronic File Management procedures outlined in the preceding sections. No design work will be done on the Master Drawings directly. For new work, copies of the Master Drawings will be acquired by the project manager to use as a reference.
Following is the folder structure for managing files for new work;
On TCCD Server
0 - Master Facility Drawings: This is where all Facility Master Plans and Models are stored.
1 - Current Projects – In House: The TCCD Project Manager obtains a copy of the relative Master Documents for use by the in-house design staff. Progress drawings and models are stored in this folder.
2 - Current Projects – Consultants: The TCCD Project Manager obtains a copy of the relative Master Documents and for use by the outside Consultants. Progress drawings and models are stored in this folder.
3 - Completed Projects – Add to Masters: When the project is complete, the TCCD Project Manager moves the final project files to this folder. A copy of these files as well as a copy of the relevant Master Documents is also placed on Buzzsaw to the same named folder. TCCD or B-CAD will use these for updating the Master Plans and Models.
On BUZZSAW – Under Folder “1 – From TCCD”
a – Master Plans – To Be Updated: When the project is complete, the TCCD Project Manager places a copy of the relevant Master Plans and Models in this folder.
b – Master Database – To Be Updated: When the project is complete, the TCCD Project Manager places a copy of the Master Drawing Database in this folder.
c – Completed Project – Add to Masters: When the project is complete, the TCCD Project Manager places a copy of the final project files to this folder.

16.0 -Revit Best Practices (Recommended)
16.1 Best Practices The following sections describe application-specific best practices as well as procedures used on all TCCD Revit projects. The following characteristics of a Revit Model can affect performance:
Complex Geometry
Multiple Parametric Relations
Multiple Constraints
Linked Files
Restarting Revit The Revit-based applications maintain model data in memory and hard disk caches to increase performance against repeated data access. Revit platform performance may benefit from a workstation restart once or twice a day, and especially before triggering the following memory-intensive tasks:
Printing
Rendering
Exporting
Compacting Central and Local Files Compacting the Central and Local files reduces file sizes when saving Workset-enabled files. During a normal save, Revit-based applications only write new and changed elements to the existing files. This can cause files to become large, but it increases the speed of the Save operation. The compacting process rewrites the entire file and removes obsolete parts to save space. Because it takes more time than a normal save, use the compact option when the workflow can be interrupted.
Design Options Preserve Design Options only as long as they are useful to the project. Even though options may not be active and visible when changes are made within the main model, all Design Options will update to maintain the model’s consistency. Consider whether options should be preserved long-term in separate models that can be linked as needed.
AutoCAD Files
Minimize the number of linked DWG files.
Make sure linked DWG files are “Clean” of any unnecessary graphics, model space debris, are fully purged and audited.
Do NOT import DWG files into Revit. Any Typical details that exist in AutoCAD should be re-created using Revit native drafting elements.
TECHNICAL DESIGN GUIDELINES D10511/15/2024[Appendix D]
Tarrant County College District BIM Standards Manual
Rev. 01 – April 1, 2016
Printed Copies Uncontrolled 104
Avoid importing AutoCAD Drawings, especially unnecessary data like hatching or line-work such as construction lines. Delete unnecessary parts and layers of the DWG file within AutoCAD and link if possible (rather than import) only the cleaned, smaller DWG.
Avoid exploding the geometry imported from DWG files. The exploding operation within a Revit-based application can change a DWG from a single-managed element to hundreds or thousands of additional elements depending on the number of entities in the imported DWG. This significantly affects the size and functionality of Revit Model.
Only link essential DWG files into necessary views.
DWG files shall be saved using the World Coordinates System (WCS) before they are linked into Revit in order to be correctly aligned.
Linked files should not contain External References.
Elements within the DWG cannot be more than 2 miles apart from each other.
In order to control the AutoCAD Lineweight from Revit, the Lineweight column within the Layer Properties Manager Dialog Box should be set to Default.
Importing and Linking Files
Unload links of all types if not used.
Temporarily unload worksets for links that are not needed in the view and reload them as required to limit memory resources necessary to open a project file.
Views
Use “Wireframe” or “Shading” display modes when working in linked file environment. “Wireframe” and “Shading” modes can be three times faster than “Hidden Line” or “Shading with Edges” modes.
Zoom in to speed up drawing and snapping.
Clear the “Snap to Remote Objects” setting in the snap dialog if you have a very dense view and snap lines appear to be shooting off in all directions.
Close unnecessary windows.
Turn off shadows in views where they are unnecessary.
Modeling
Until component types are determined, use the generic version of elements such as walls, doors, windows, slabs and roofs, which incorporate less geometry.
Break up large models into 150MB-200MB each.
Regularly review and fix warnings by going to the MODIFY Ribbon Tab and clicking on the Warnings option located under the INQUIRY Panel.
When saving before closing a file, keep only a simple Drafting View open to accelerate saving and subsequent opening of the file (such as “Starting View”).
It is recommended that 3D views should be closed when saving to Central, since the Revit-based applications will regenerate this complex view as part of the save process.
Save to Central several times a day.
D106
Tarrant County College District BIM Standards Manual
Rev. 01 – April 1, 2016
Printed Copies Uncontrolled 105
Reload Latest several times a day.
Relinquish your Workset(s) & borrowed elements at the end of the day.
Third-Party Applications TCCD recognizes that there are multiple third-party applications currently available on the market that are able to run simulations and/or analysis within the Revit-based applications. However, regardless of the software used to run simulations and/or analysis within the Revit-based applications, the results must be brought back into the Revit 3D Model. This will ensure that the Revit 3D Model has the latest and most current information.
Worksets When working with Worksets, users must follow these steps to ensure changes are saved to both the Local and the Central versions of the Revit 3D Model file, as well as relinquishing previously owned Worksets.
Synchronize with Central
Save to Local
Relinquish All Mine
Project Templates Project Templates provide initial conditions and predefined settings for a project, such as generic project information, unit settings, predefined views, and plotting settings.
Using the TCCD Templates All Revit projects should be created using one of the templates provided in the TCCD Revit Support Files, which are:
2016 TCCD Architectural Template.rte
2016 TCCD General Template.rte
2016 TCCD Electrical Template.rte
2016 TCCD Mechanical and Plumbing Template.rte
2016 TCCD Structural Template.rte
16.2 View Templates View Templates are a collection of View Properties, such as the Discipline, the Sub-Discipline, the View Scale, the Detail Level, and Overrides of Model and Annotation Objects that are common for a View Type, such, a Plan View, an Elevation View a 3D View, etc. Some View Templates are provided within the MEP Templates to address the issued described within the

16.3 Levels and Plan Views The Revit-based applications create a relationship between the Level and the First Floor Plan and Ceiling Plan, so when the Level Name is changed, the associated name for the Floor Plan and the Ceiling Plan updates automatically. Users will be given the option to rename the corresponding Level Views (Floor Plan and Ceiling Plan) if the Level Name is changed. If so, the relationship between both will be broken. It is crucial to maintain this name relationship between the Level and the Floor Plans. Plan Views should be created by making a copy of any of the existing Floor Plans and/or Reflected Ceiling Plans Views Category by using the tools on the VIEW Ribbon. Under the CREATE Panel, expand the Duplicate View Pull Down Menu to select the Duplicate View Option as shown in the image to the right.

By default, the new Floor Plan and/or Ceiling Plan will be placed under a Category named “???”. To associate the new View to the right Category, either change the Properties as previously discussed (Project Browser Organization section) of the View or apply a View Template.
Views Views, such as elevations, sections, callouts, 3D, etc. will be created within the Revit Models as the project evolves. By default, all these types of Views will be placed under a Category named “???”, as shown in the image to the right.
16.4 Copy/Monitor The Copy/Monitor tool helps to monitor and coordinate changes between teams from different disciplines, which reduce mistakes and expensive rework. The copy functionality copies grids, levels, columns, walls, and floors from a linked project into a host project. You can modify these copied elements, which are automatically related to the original elements. The monitoring functionality sets and maintains relationships for those elements in the host or linked project. To start the Copy/Monitor Tool, go to the
COLLABORATE Ribbon Tab and click on the
Copy/Monitor located under the Coordinate Panel and then select the Select Link option. The first step when using the Copy/Monitor Tool is to select Options as shown in the image to the right. This will open the COPY/MONITOR OPTIONS Dialog Box. Make “Categories and Types to copy” setting adjustments as necessary.
16.5 Creating Sheets Creating Contract Documents in “Revit” is accomplished through sheets, in which Views have been added. Sheets have been preconfigured to work in conjunction with the discipline templates file and with the shared parameters file. It is strongly recommended to use TCCD Templates to make sure that ALL of the shared parameters are defined appropriately.

NOTE: Once the Cover Sheet and Title Sheets are loaded, they will get populated with the Project Information provided in project properties described above.
16.8 Drawing Information Drawing Information is data relating to an individual sheet of the Border Sheets in a project. All the available Cover Sheet Information fields are listed under the Identity Data and Title Text Parameter columns. To update the Drawing Information of a sheet, use either one of the following methods:
Enter the information directly on a sheet by clicking on the text placeholder within the sheet and update the text as desired.
Click in an empty space in a sheet view and this will open the Sheet INSTANCE PROPERTIES Dialog Box. Change the values as needed. It is strongly recommended to use TCCD Templates to make sure that ALL of the shared parameters are defined appropriately.
16.9 Purge Unused The Purge Unused command unloads any unused Families and Family Types along with Groups and Styles, reducing the file size of the Revit Model file. To purge the Revit Model, go to the MANAGE Ribbon Tab and click on the Purge Unused Tool located under the PROJECT SETTINGS Panel. This will open the PURGE UNUSED Dialog Box as shown in the image on the right. Expand the desired category and click on the “OK” button.

The mission of the Facilities Department at TCCD is to successfully integrate district facilities. In delivering the mission, the Facilities Department’s number one goal is to provide for safe, healthy and comfortable building environment for TCCD employees and the many thousands of students and visitors in TCCD buildings daily. By adhering to the below outlined AutoCAD Standards it allows TCCD to develop and maintain graphic and related information which users can manage, operate, maintain and improve the facilities, grounds, and related infrastructure systems of the TCCD.
The purpose of this document is to serve as a specification for producing and delivering AutoCAD drawings for TCCD Facilities Department. These requirements must be followed and met by in-house staff and outside consulting firms and their sub consulting firms. The drawings shall be re-submitted after all requirements have been met and before a project can be closed out and final payment is received from TCCD. All specified materials must be submitted electronically to the TCCD Facilities Department for approval in accordance with production standards and special instructions described throughout this document. A copy of the AutoCAD Standard Checklist found in this document (Section 2.0 and Appendix D) must be signed and submitted with the AutoCAD drawings being delivered during any phase (Predesign Phase, Schematic Design Phase, Design & Development Phase, Bid Set, Construction Document Phase, Addenda and As-builts, and Record Document Phase) of the project. By signing and submitting the AutoCAD Standard Checklist the vendor (architect, engineer, contractor, etc.) is assuring all materials submitted meet the required standards and guidelines set forth in this document. These standards are issued to promote the development of AutoCAD drawings suitable for use in the TCCD AutoCAD environment. Consistency and compatibility with existing TCCD AutoCAD documents can only be achieved when these standards are strictly adhered to. Electronic drawings produced and submitted in accordance with these standards have significantly greater value to the college, Architects, Engineers and Contractors delivering AutoCAD documentation to TCCD.
TCCD consultant contracts and design guidelines may reference this document. Each of the following sections contains the most essential criteria for developing AutoCAD drawings for use in the TCCD AutoCAD environment. Refer to “Consultant Deliverables” section for specific requirements. Refer questions to the Facilities Department at TCCD.

These standards are to be followed by TCCD AutoCAD users as well as all outside consultants providing AutoCAD drawings to TCCD. The AutoCAD standards will be reviewed annually. Recommendations will be considered during the review. Drawing standard deviations will only be accepted in project drawings with prior approval of TCCD. TCCD AutoCAD Standards are based on the U.S. National CAD Standards (NCS), Version 6. Modifications and refinements have been made to align these AutoCAD standards with TCCD’s facility documentation needs. In instances where there are differences between the TCCD AutoCAD Standard and the NCS standard, the TCCD AutoCAD Standard shall control. For items not covered in the TCCD AutoCAD Standard, refer to the NCS standard for general guidance and consult with your AutoCAD manager. TCCD encourages employees and consultants to refer to the NCS as an additional resource. The NCS consists of:
AutoCAD Layer Guidelines, published by the American Institute of Architects (AIA)
Uniform Drawing Systems (UDS) Modules 1-8, published by the Construction Specifications Institute (CSI)
Plotting Guidelines, published by the Tri-Services and U.S. Coast Guard TCCD is a subscribing member of NCS and has an enterprise license for use of the National AutoCAD Standards document.
TCCD AutoCAD Standards generally follow NCS terminology, some of which may not be familiar to all AutoCAD users. This will be especially true of the terms used to describe different categories of electronic files used in creating AutoCAD drawings. Please refer to NCS, your CAD manager, or the Autodesk Help page for any definitions as needed.
No, but since AutoCAD is the primary Computer Aided Drawing (CAD) platform of TCCD, the AutoCAD Standards Manual is written in this context. In that sense, the manual will refer to settings in AutoCAD and uses the “language” of AutoCAD. However, this does not mean that these standards do not apply to users of MicroStation, TerraModel, or other “non-Autodesk” drafting packages. It is assumed that in most cases users of other platforms are also familiar with AutoCAD and can therefore make the appropriate adjustments to apply the intent of the standard within other AutoCAD platforms. For those users that may not be familiar with AutoCAD, please coordinate with your AutoCAD-knowledgeable associates to understand portions of the standard that may elude you.
The term “Vertical Applications” refers to applications such as Land Desktop (LDT), Civil 3D (C3D), Architectural Desktop (ADT) now known as AutoCAD Architecture, and

AutoCAD MEP (MEP) that run “on top” of AutoCAD. It is not practical to produce and maintain an AutoCAD standard that addresses all of the nuances and requirements of vertical applications. However, it does consider some of the predominant vertical applications that are central to efficient drawing production such as AutoCAD Architecture and AutoCAD MEP. It is important to understand that the standard does not discourage you from taking advantage of features of vertical applications that are not addressed here. The use of product features that support the mission of the TCCD AutoCAD Standards is encouraged.
The AutoCAD standard will be reviewed, and updated where deemed necessary, as a planned annual effort. Updates to individual modules, or new sections, may be issued at any time when significant changes are needed. The AutoCAD Standards Manual will clearly reflect the revision number and date within the footer of each section.
Printed Copies of this manual and sections are “uncontrolled” as noted in the footer of each page of the AutoCAD Standards Manual, meaning there is no attempt made to systematically update printed version of the standard. The online AutoCAD Standards Manual found on the TCCD Website is considered the “official” version and should be used to avoid potential reference to out-of-date printed copies.
BCAD will provide staff training and on-going support regarding the development, maintenance and implementation of TCCD AutoCAD standards as needed. Should you or any of your team members require such training and support, contact your project manager for further direction.

TCCD’s goal with these Standards is to create Facility Drawings that are consistent in appearance and which integrate the required flexibility to meet the fluid and expanding needs of TCCD. We believe these Standards are comprehensive and practical … and we invite our Consultants to utilize them in their entirety. It is however, not TCCD’s intention to add undue burden on the Consultants with these Standards. TCCD understands their Consultants may have spent considerable effort and expense in developing their own in-house standards and production methods. In defining the “Consultant Deliverables”, TCCD has attempted a compromise … one that provides TCCD with the structure and flexibility needed with the drawings, yet still allows the Consultant to maintain most of their production methods.
Below is a Checklist for Consultant Final Deliverables:
1. Introduction to TCCD AutoCAD Standards a. All AutoCAD drawings shall be developed in accordance with the most current version of TCCD BIM Standards.
2. Consultant Deliverables a. TCCD Consultants will be required to follow ALL of the items outlined in this section.
b. TCCD Consultants are encouraged, but NOT required to follow the best practices described in this document or the requirements NOT outlined in section 2.0 – Consultant Deliverables.
3. Units & Precision
a. Units & precision requirements of all drawings will be adhered to as described in section 3.2 Units & Precision.
4. Coordinates & Orientation a. Consultants CAN use campus wide project base point established by the civil engineer for the duration of the project. At the final project closeout stage, however, consultants are required to relocate project insertion point of model drawings to the base point as described in the section 4.1 Drawing
Origin.

For the purposes of establishing unit and precision settings, drawings are broken into three categories as follows:
Category Types of Work Included Survey Land Surveys, Plats, Property Deeds Site Work Civil, Landscape, and Site Utilities drawings for wholly site related documentation Building Architectural, Structural, and MEP&F drawings Within TCCD Facility Drawings all three types may be employed. For example, TCCD South Campus might have grounds topographical drawings, site utilities drawings, and building plans. The building plans may include architectural, structural, mechanical, plumbing, and fire protection as-built conditions drawings.
Imperial units are the standard system of measurement for TCCD drawings unless S.I. (International System of Units) units are specified by the reviewing agency, or an industry standard for the type of work being performed.

Drawing “Length Precision” settings are not intended to establish or imply a required degree of field or construction precision. For example, four decimals of precision (0.0000) for a site utilities drawing does not indicate that four decimals of utilities placement as-built information accuracy is expected or required. Dimensioning precision is completely independent of drawing precision. Dimensioning precision, unlike drawing precision, is generally related to the expected degree of construction precision, which will be discussed in Annotation module.
If you insert an architectural drawing (where the insertion units are inches) into a civil drawing (where insertion units are feet), the inserted architectural drawing will be automatically scaled down by a factor of 12 so that it is in the appropriate scale relative to the current (civil in this case) drawing. This should be addressed by the following: 1. Set the "Default settings when units are set to unitless" to "Unspecified-unitless" as shown below. This way, no auto-scaling will occur if either the inserted or current drawing has INSUNITS set to "unitless.”

Buildings in Model Space Draw or insert building drawings in model space so that the lower left intersection of the outermost column/building lines that remain constant on most floors are placed at 0,0,0. In order to ensure the proper insertion of external references (Xrefs) and the stacking of floor plans, the origin point for an entire building or site must be consistent between model layers. Once the origin is established, it should not be changed.
Site Drawings in Model Space Draw or insert site drawings in model space on the coordinate system used for the project. This may be an arbitrary coordinate system assigned by the surveyor or a formal coordinate system, such as State Plane Coordinates. All site related drawings should exactly overlay this coordinate system. Once the origin is established, do not change it unless a global correction to a new coordinate system is required. All survey drawings should be tied to existing survey monuments and bench marks.
Paper Space ONLY title block, sheet numbers, drawing titles, stamps, general notes, and tables should be placed in the paper space. Any drawn objects along with drawing related annotation should go in the Model space.

When placing the TCCD standard title block in a sheet file, place the lower left corner of the blue “no plot” boundary of the title block at 0,0,0. The title block should default to this origin when inserted. This will allow the sheet to have the correct margins when plotted to “extents” and centered on the page.
Model Space Do not set the drawing limits any larger than necessary to accommodate the drawing in model space. In other words, clean-up drawings and do not leave drawing debris floating in the model space that is not part of the drawing.
Paper Space No entities shall be located outside the blue “no plot” boundary for the title block in paper space. This is critical since title blocks are plotted “by extents.”
Buildings In model space, buildings are typically oriented orthogonally with the longest edge of a building running horizontally.
Site Drawings In model space, the site should be oriented such that true north is the top of the drawing area. In paper space, the preferred orientation of viewports is true north generally toward the top or left edge of the sheet. When the view of a model space region, as established through a viewport in paper space, needs to be rotated, it is absolutely critical that only the view is affected and not the actual orientation of the model space drawing. DVIEW/ TWIST and MVSETUP are two of the acceptable methods to orient a view of a model space drawing in the viewport. All drawings should be saved with the User Coordinate System (UCS) oriented to the World Coordinate System (WCS). The UCS icon should be displayed at all times to let you know if you inadvertently rotated the UCS.
Because building drawings are often referenced into site drawings and vice versa, the process for inserting, rotating and scaling one drawing type into another should be clearly established, documented and understood by AutoCAD professionals on multi-discipline projects. When inserting a “building” drawing into a site drawing (or vice versa), the procedure described here is what TCCD expects to minimize the work required in updating the drawing. The explanation below assumes that a building drawing is being referenced to a site drawing, but the procedure is similar for the reverse case.

The “tie point” is the most critical piece of information to know when inserting one drawing into another. This is an arbitrary point on the building that is determined by the design professional and should not change. The location and alignment of the building as it relates to this point should be communicated to those working on the site drawings to ensure the building is inserted at the correct location. In this case, the tie point is the middle of the building.
1. Xref (attach) the building drawing in a new model file (Arch Model). This file should be named according to the “Model File Naming Convention” (see Electronic File Management module). Within the Arch Model: a. Turn off all layers in Arch Model except the ones you wish to appear in the target drawing (Site Model). b. Temporarily Xref (overlay or attach) the site drawing (Site Model) into Arch Model to aid in proper alignment of architectural drawing. c. Move building in Arch Model to place the tie points between the Arch Model and Site Model exactly on top of each other.

d. Using the tie point as the point of rotation, rotate the building in Arch Model so it aligns with the established bearing of the building. In this case, that means the line from the tie point to Point A. e. Scale architectural building envelope down (by a factor of 12 typically). In newer versions of AutoCAD scaling may happen automatically if the units are properly set in both drawings. 2. Document this process for all AutoCAD professionals on project. 3. Detach Site Model from Arch Model because the building drawing is properly set. 4. Xref (overlay) Arch Model into Site Model for use in site design. 5. If the building envelope is revised in the future, the following steps should be followed to swap out the architectural drawing without rescaling, aligning or rotating it: a. Replace the old building drawing with the new one. They should have the same name. b. You may move the old building drawing to an archive folder or simply delete it. c. Open the Arch Model drawing and the Xref will automatically be updated and the changes will be apparent (no scaling, aligning or rotation needed).

Virtually all vector-based AutoCAD systems support the concept of layers. This function allows building design information to be organized in a systematic fashion, facilitates the visual display of the information on a computer screen, and allows the information to be efficiently converted to the conventional print media of drawings. Efficient use of layers can reduce document preparation time and improve document coordination. Organizing data by layers allows a single AutoCAD file to contain a wealth of information about a building or facility. By turning selected layers on or off, data can be created, reviewed and edited according to a hierarchy that simulates the physical organization of building systems, the relative position of building elements, or the sequence of construction.
The layering standard is based on the NCS standard, which breaks up layer names into four data field types 1. Discipline Designator 2. Major Group 3. Up to 2 Minor Groups 4. An optional Status field. The format for standard TCCD layer names is shown below:
An example of Architectural Interior Full Height Wall Dimension for New Construction shown below:
The Discipline Designator for layers is the same as the Discipline Designator used for sheet numbering and electronic file naming. The following table defines the designators to be

Above is a typical layer name showing the required & optional data fields. The mandatory Discipline Designator field is highlighted. The Discipline Designator is always one (1) character, and follows the NCS except for the addition of “K” for Space Tracking and “U” for Site Utilities and substituting “L” for Life Safety instead of Landscaping.

Note that the NCS provides an option for Level 1 and Level 2 Discipline Designators. A Level 2 designator would append to the Level 1 designator to add a level of detail, such as AI for Architectural Interiors or SD for Structural Demolition. The TCCD layer standard DOES NOT use the Level 2 Designator and therefore drops the level designation and simply refers to the Discipline Designator.

The Major Group is used to define the “building system,” where “building" does not literally mean building, but a major project system or component. The prescribed Major Group field codes (four-character abbreviations) shown in the Appendix A are logically grouped with specific discipline designators. However, any Major Group may be combined with any prescribed Discipline Designator, provided that the definition of the Major Group remains unchanged. Therefore, any reasonable combination of the prescribed Discipline Designators and Major Groups is permitted. Some examples of Major Groups include WALL, SSWR (sanitary sewer), and COLS (columns). The Major Group is always four (4) characters in length. User modification to the Major Group field is not permitted. Major Group options are limited to those used within the NCS and layer tables for this standard. Above is a typical layer name showing the required & optional data fields. The mandatory Major Group field is highlighted.
The Minor Groups are optional, four-character fields and are used to subdivide Major Groups by material, type, orientation, or other differentiating characteristics. For example, A-WALL-FULL denotes Architectural, Wall, Full-height. A second minor group may be used for still further delineation of the data contained on a layer. For example, A-WALL-FULL TEXT indicates Architectural, Wall, Full-height, Text. The prescribed Minor Group field codes (four-character abbreviations) shown in the Appendix B are to be logically grouped with specific Major Groups. However, any Minor Group may be used to modify any Major Group, provided that the definition of the Minor Group remains unchanged. Therefore, any reasonable combination of the prescribed Major and Minor Groups is permitted. The standard allows for up to two Minor Groups, and they are always 4 characters in length. A typical layer name showing one optional Minor Group field: A typical layer name showing two optional Minor Group fields:
NOTE: User-defined Minor Group field codes are permitted. They must contain four alphabetic and/or numeric characters and/or "~".

The single-character Status field can be used to designate the status of the work or a construction phase as shown in the table below. A typical layer name showing the location of the optional Status field:
Note the following when using Status Field Codes • Apply the Status Field Codes consistently throughout the project. • Do not use multiple status designations simultaneously. For example, do not use “E” in combination with “A”, such as V-SSWR-MHOL-E-A to indicate an existing sanitary manhole that is abandoned. When dealing with TCCD facility master drawings, inherently all drawings show existing conditions, therefor “E” designator is not needed. A majority of the drawings generated and managed by TCCD will be facility and site master drawings indicating existing conditions for all disciplines. However, some departments will be creating their own drawings of renovations, proposed conditions, what-if studies, etc. While these files might only exist with-in their local drives, they should still follow AutoCAD standards outlined in this document. Once the new information needs to be incorporated into the masters as as-built information, the process will be streamlined. TCCD’s layering standard limits the use of the Status field to very specific cases. Understanding the rules of using the Status field requires one to understand the standards for how existing information is separated from new work in model files. The TCCD standard is to have separate model files for existing information (master files) and new information (local files generated by TCCD design and maintenance staff). It is still beneficial to use the “N” designation in new model files. The “E” designation should be used when it is necessary to combine existing and new work in the same file. Those combined files should NEVER override the master drawings of existing conditions.

Note that the use of the Status field as allowed by the TCCD standard is still optional, but should be applied consistently on any project on which it is used. There is no requirement to use the Status field – this is a project decision – use the field if it helps to control layers associated with work status or construction phasing that need to be isolated, turned off, or frozen.
Using the Status Field for Model Files of Existing Data Use of the Status field in model files that contain existing project data shall be limited to the following:
D – for existing items that are designated for demolition M – for existing items that are designated to be moved Using the “D” and “M” status designations will allow for items on those layers to be frozen or turned off so that model files with existing data, when x-referenced into model files of new work, will accurately reflect the project in “final design” view.
Using the Status Field for Model Files of New Work Use of the status field suffix for layers within model files of new work shall be limited to the following:
N – to designate new work within existing facility/ site F – to designate future work, not part of the current contract T – to designate temporary work 1-9 – to designate construction phasing
TCCD standard layers are shown in layer tables in Appendix C. The layers should be deployed into AutoCAD drawings using appropriate AutoCAD templates and Layer Library Manager (LLM) Add-in. AutoCAD Templates and standard layers are organized by discipline.
Note the following when using standard layers:

Insert blocks on the layer that the block is most closely associated with. For example, a sanitary manhole symbol might be inserted on C-SSWR-MHOL layer.
Do not reproduce the General Layers to other disciplines and change the Discipline Designator, such as creating an E-ANNO-SYMB layer in lieu of the G-ANNO-SYMB. The General Layers are intended for use in all disciplines and should retain the “G” Discipline Designator when used.
o Note that some disciplines do include specific ANNO layers such as C-SSWR-ANNO when it is common to need to isolate certain discipline specific text.
Do not put anything on layer zero or on the Defpoints layer. Defpoints is not recognized by NCS and receives data that is generated by AutoCAD. For these reasons, notes intended for users to see but not plot should be put on other “no plot”

If there are multiple options for layers, pick the most general. Only use more specific layers if you know that greater granularity is needed in the layer assignments.
layers. Note that NO information should exist outside the title block in paper space because it will be included in the “extents” when plotting the sheet.
Do not change the line thickness or line type of a standard layer. It is acceptable to force a line type on individual entities in certain cases, but do not change the line type associated with the layer.
o Refer to the “Layer Properties / Line Types” sections below for instances when line types can be forced.
Making Decisions about Layer Selection TCCD’s layering standard follows the NCS layering standard (AIA layering system). This standard provides discipline-based layers that draw from the NCS standard where needed and add layers within the discipline where needed. Layers that are added strictly follow the NCS layering syntax and format. Generally, the NCS provides more than enough layers to distinguish aspects of an AutoCAD drawing. An effort has been made in developing the TCCD standard layers to narrow down the NCS layers to those commonly needed and to minimize the number of decisions AutoCAD users have to make when assigning layers. For example, the NCS standard provides 10 structural layers for structural bracing, allowing bracing to be defined by material and orientation. However, the TCCD standard only includes 1 of the 10 layers (S-BRCG) of the standard database of layers that is automatically deployed using TCCD’s AutoCAD template. This should suffice for most projects but the standard does allow for the user to add suffixes when more detail is needed. In many cases, there are multiple choices for a layer. Unless the more detailed distinction is necessary, always select the simplest (most general) layer. Example - Layer Choices for Columns* S-COLS S-COLS-PRIM S-COLS-RCON S-COLS-WOOD S-COLS-ALUM * These are not actual TCCD layers – this is an example The following approach is taken in creating and maintaining the list of standard TCCD layers: • Number of layers are limited to the greatest extent possible to avoid drafters having to make decisions about which layer to use, while still providing enough detail to adequately manage the layers on drawings for appearance and plotting • The general layers should not be re-created within every discipline. The general layer groups can be added to any drawing but the “G” prefix should remain.

• Major Groups that are in the NCS standard, but provide more granularity than needed, are limited to one group. For example, the TCCD standard only uses the PVMT (Pavement) Major Group, eliminating similar Major Groups of ROAD, HGWY. • Minor Group 1 choices of different types of material are generally eliminated from the TCCD standard such that the layer for columns is simply S-COLS, eliminating the layer choices of S-COLS-ALUM, S-COLS-RCON, S-COLSSTEL, and S-COLS-WOOD.
Each standard layer, in addition to a layer name, includes definitions for the layer properties of color, line type, line thickness, plot style, and whether or not the layer is plotted. The following should be noted in reference to the standard TCCD layers: • The TCCD plotting standard is to plot by color representing a specified line weight, NOT by the line thickness assigned to the layer. The TCCD plotting standard is color-based (CTB) rather than style-based (STB).
• For black & white plotted lines, the colors are limited to the 1-9 primary colors in the AutoCAD Color Index (ACI). For Grey Lines (referred to as halftones) a transparency value is assigned to the layer property rather than screening assigned in the plot style table (CTB) file. For lines plotted in color a specific set of colors will be identified.

• Because of the above, only one CTB file will be required for ALL TCCD drawings for all disciplines. Each of the layer properties is described below (Sections 5.9 and 5.10).
Each standard layer is assigned color based on a number of considerations including the following: • Colors are selected logically based on what line weight the layer will need to print. For example, a wall layer is green, as it needs to print darker, and layers used to define hatch patterns will typically be light gray, with transparency assigned as needed, so that the hatch "does the talking" but does not dominate the drawing. • Colors are selected to clearly show up on black backgrounds, with consideration given to other common background colors that some users select. Because plotting is based on color assignments, changing the color of layers will impact plotting. Therefore, it is not acceptable for users to modify the color assignments, unless approved by a Senior AutoCAD Manager.

Some additional rules should be observed for projects with black and white plotting:
Only change colors if necessary - for example, if you are color blind and have trouble seeing certain colors on screen. Do not change just because you like red better than yellow. • Prior to saving the drawing, colors should be reset to the assigned layer color with Layer States Manager in AutoCAD.
Each TCCD standard layer is assigned a line type from one of five approved line type sets, described in the table below.

The General group includes line types that are part of AutoCAD, and are used on layers in all disciplines. The Site related, Building related, and mechanical/electrical/plumbing line type sets are self-explanatory. In a few cases there may be line types duplicated between these sets. The Sized Utility set includes line types such as ------16”G--- for 16” Natural Gas line. These are for situations when the size of the utility as part of the line type is appropriate. Examples of this include: • Agency, client requirements • Planning drawings where utility size needs to be identified without cluttering up the drawing • Utilities where safety is a concern, such as high pressure gas lines When this line type is necessary, simply override the line type of the layer to assign a “sized” version – such as changing the standard assignment of -------G------- for the C-NGAS-UNDR layer to ------16”G---------. Do not create separate layers for each size of utility. Do not change the line type assigned to the layer.
TCCD_acad.lin File AutoCAD references a default acad.lin file for the line type definitions. TCCD Standards defined and created some custom line types (NFPA compliant fire walls, utility line types, mechanical line types, etc.). All TCCD AutoCAD users as well as outside consultants MUST use TCCD provided TCCD_acad.lin. Refer to Appendix E for standard line types.

The TCCD plotting standard is color-based (CTB) rather than style-based (STB). This allows tremendous flexibility in the manner in which shading and color are treated.
TCCD_Standard.ctb is the Plot Style Table to be used with ALL TCCD Facility Master drawings. This plot style table allows for both Black & White as well as Color plotting. All paper space layout tabs should have the following setting:
All standard layers have their own color and line type assigned (listed in the Appendix C). If necessary, users may modify the color of a layer for the drawing presentation, such as showing certain layers in color. For example, all layers, by default, are assigned to plot as black. However, by modifying the color property of one or more, items on those layers will plot in an assigned color.
Screening Screening may be accomplished by setting the Transparency Property for a layer to the appropriate value (such as 50%).

Setting Existing Conditions as "Background" A common use of screening is when it is desired to include existing condition floor plan information in the background of a Mechanical or Life Safety drawing showing discipline specific features, with the intent of having the floor plan show up while not overwhelm the drawing. To accomplish this, simply select the layers associated with the existing conditions and set the Transparency to 75%-50% (depending on your printer) for those layers. It is critical that screened areas of plotted, scanned, and copied sheets be checked for appropriate appearance since screening tends to fade or darken when copied (especially after successive copying) or when scanned. Ideally, original plotted sheets should always be issued, but if copies are necessary, they should only be made from original sheets.
Introduction When considering all disciplines in a project, number of layers needed is overwhelming to manage. Using a drawing template with all of the layers present is helpful, but sometimes gets cumbersome if you only need a handful of layers to work with. To make drawing process and layer management process, TCCD is implementing a Layer Library Manager. LLM is a third party developed Add-in which appears in the AutoCAD ribbon after it is installed.
LLM is used to quickly import layers for any discipline into your drawings with already pre-defined layer properties (layer, color, linetype, lineweight, transparency, etc.) Implementation Use the following steps to acquire and install LLM on your workstation:
Add-in can be found at Autodesk App web page: apps.autodesk.com

When annotating AutoCAD drawings, a few guidelines should be followed:
Annotation of drawing items should always be on layers with “ANNO” or “TEXT” as a major or minor group. The General layer group includes a set of G-ANNO layers that should be used in all disciplines. The Discipline Designator for these layers should always be G; it should not be changed to A or C or any other Discipline Designator.
When annotation will repeatedly occur in a drawing type, such as sanitary sewer piping, which needs to be controlled separately from the rest of the annotation in the drawing, it is acceptable to create layers such as C-SSWR-PIPE-TEXT.
Annotation will typically be in the model space view of a model file. And it should be placed on the annotation layers as needed.
The use of Arial family fonts for the TCCD standard has been selected. Follow these rules when using these fonts:
Use a width factor of 0.8 (except for Arial Narrow) on all text styles, but most importantly in general notes, tags, and dimensions.
To get italics, apply italics option in the text editor as needed, NOT in the Font Style.
To accentuate items of critical importance, use bold option in the text editor, NOT in the Font Style. Underline in the text editor can also be used.
ALL of the text, dimensions, multi-leaders, tags, and symbol blocks should be set to “Annotative” and only contain appropriate annotation scales assigned. A few text styles were defined as non-annotative to be used with in block attributes and line type definitions only.

Text Style Names Text styles are named based on the use:
The “Standard” font style will remain in all drawings as it is a default AutoCAD style and it cannot be deleted. Because most AutoCAD users modify this style to match their own drafting standards, this is not a recommended style definition to use. If drawings are acquired from outside consultants with a different definition of this style, it may adversely affect your own drawing. In TCCD Standards, “Standard” font style is defined as follows:
Some additional text styles were defined to be used with TCCD standard block attributes and Line Types. If you have any questions regarding the use of these text styles, contact your CAD manager.

Text and dimension text should always read left to right and bottom to top. When text is oriented at an angle between horizontal and vertical the following guide should be used in determining text orientation. Notice as text approaches vertical orientation, as in the top left and bottom right quadrants below; it is read top to bottom.
Use associative dimensioning whenever possible.
Never force or override dimensions (do not manually enter 10’-6” as a dimension if the drafted distance is actually 10’-6 ½”).
o The exception to this might be a detail that was not drawn to scale. In this case the dimension would read NTS.
Never explode dimensions.
Model space entities shall be dimensioned in model space and paper space entities shall be dimensioned in paper space.
o While cross-space dimensioning is possible, this should be avoided unless necessary for practical reasons.
Dimension precision is independent of drawing precision, which is covered in the Units and Precision module.
The overall objective with dimensioning is for all dimensions of a similar type to have a uniform appearance in terms of arrowheads or ticks, offsets, text height, and other dimension settings. To accomplish this objective, TCCD has developed common dimension

styles to achieve dimensioning consistency throughout all drawings. TCCD dimension styles should be used for all dimensioning. Annotative dimension styles are provided for decimal and architectural formats. Decimal format dimension styles use arrows only and are used for Feet units. Architectural format dimension styles use ticks and are used for Inch units (displayed as: 10’-6 ½”)
Annotative dimension styles are the only method of dimensioning permitted by the TCCD AutoCAD Standards, because they control the scale automatically. Modifying placed dimensions are subject to the following rules:
Do not modify TCCD Dimension Style definitions
If a placed dimension requires modifying a property (i.e., text position, flip arrow, extension line turned off, etc.) you can do so via the properties palette or right-click context menu.
Only applicable scales should be assigned to ALL annotative objects. Avoid using “Add scales to annotative objects when the annotation scale changes”
Dimension Style Use by Drawing Category As described in the Units and Precision module, drawings are broken into three categories; Building, Site Work, and Survey. For Building work, which encompasses Architectural, Structural, and MEP drawings, dimension styles with “Inch” units and “Tick” terminators should be used. For Survey and Site work drawings, dimension styles with “Feet” units and
“Arrow” terminators should be used.

Civil Example
All callout type annotation shall be made using the TCCD Multi-leader styles described below. Rules of good drafting, such as having the same length for all lines of Mtext whenever possible and not crossing leader lines, should be followed on all drawings.
Callouts with leaders should always be created using Multileaders. The “leader” and “Qleader” methods should not be used.
Leader style and all Multileaders used in the TCCD drawing must be annotative. Both right and left justified text can be used in drawings, with left justified being preferred. Regardless, the left justification or right justification should be consistent on the entire drawing set. Key settings are listed below:
Text – multi-line text, ALL CAPS, Arial, at 3/32” text height (Use TCCD_Standard text style).
Justification – Right/top justify if leader on right and left/top justify if leader on left (see example below).
Leader – There should be ½ text height (3/64”) between text and landing line of leader, and the landing line length should equal the text height (3/32”). The leader line should always be straight, not splines (area callout is the exception).
Terminator – Size shall be 3/32”. The default terminator type is a closed, filled arrow. However, other terminator types are discussed in the subsection titled “Leader Terminator Types” on the next page.

Leader Terminator Types It is important for the drawings to convey information in a clear, consistent, and effective manner. To accomplish that TCCD standard requires the use of different leader terminations when calling out objects on the drawings. The standard terminator types are described and pictured here:
Closed filled – This is the most common type of arrowhead and should be used for pointing to a general location of an object, such as top of wall. End of arrowhead should touch the object.
Dot blank – Use this type for identifying a small object such as rebar in section view (in fact, this will almost exclusively apply to rebar).
Dot – Use this type for adding notes to the dimension string.
None – Use this type for pointing to a particular location on an object such as a box highlighting a section that is detailed elsewhere or calling attention to a revision cloud with a note.
Integral – Use this type for pointing to an object or region but not a specific location on the object or region.
Loop – Use this type for identifying conduits, pipes, horizontal rebar, etc.

If a placed Multi-leader requires modifying a property (i.e., text size, different terminator symbol, etc.) you can do so via the properties palette or right-click context menu.
Only applicable scales should be assigned to ALL annotative objects. Avoid using “Add scales to annotative objects when the annotation scale changes”.
Do not explode multi-leaders.

In general, all tables should be created using the “Insert Table” method. It is not acceptable to create tables by simply drawing lines and text. It is understood that Civil 3D, AutoCAD Architecture, AutoCAD MEP and similar systems that run on top of AutoCAD create tables that are linked to the drawing data such as door schedules. These are certainly acceptable – see Properties and Layout below for differences in how these tables are treated in terms of paper space versus model space. Table editing is much simpler and more efficient when using a Table Object in AutoCAD. A TCCD table style called “TCCD_Standard” has been created for general table creation and is available via the TCCD drawing template. All tables should be placed on the G-ANNO-TABL layer unless a more discipline-specific layer assignment is needed. All tables that are created using the Insert Table method in AutoCAD should be created in paper space. See Appendix F for the standard schedule format based on the NCS v6.0.

The ability to link tables from Microsoft Excel to AutoCAD can be extremely beneficial in terms of accuracy and efficiency.
Do not use OLE links for this as there are significant formatting issues and other limitations. It is strongly encouraged to use this functionality as it leverages the ability to use calculations in Excel, which is ideal for tables such as space square footage tracking and different occupancy type calculations. A Data Link can be created prior to, or during the Insert Table process. The following rules should be followed: 1. Format your Excel Table the way you want it to appear in AutoCAD. 2. Select the range that encompasses your table in Excel and name the range – use a logical name like "Occupancy_Table". Note that you can have as many named ranges as you like in the Excel Workbook – simply name each range that you want to link to AutoCAD. 3. Create a Data Link to the Excel file and the named range in the file. 4. Import the “TCCD_Standard” table style and set it current. 5. Create a table using Insert Table and select the option to create the table from the Data Link created above. 6. Modify the table by setting the “Cell style” and “Row style” to “Title”, “Header”, and “Data” as necessary to use the table style properties.

File Management of Linked Tables It is important that any Excel files that are linked to tables in AutoCAD reside under the CAD directory in the project folder, specifically in the “3 – Misc” folder, as described in “Electronic File Management” section. These files should be clearly under control of the CAD designers and drafters such that other project team members do not have "ready access" outside of the CAD folder where they may alter the Excel file without realizing the information is linked to a CAD drawing. If necessary, the Excel file should be protected, however password protection should not be used. Alternatively (or in addition) the file properties should be set to “Read-Only”. The naming convention for Excel files linked to AutoCAD tables is the same as the model files naming convention found in the Electronic File Management module.

In order to employ the best drawing practices, productivity, and efficient file size management, follow best drawing management practices including:
Ensure that all lines that should meet at intersections do meet at intersections (always use OSNAP’s).
Avoid crossing leader or dimension lines.
Draw objects accurately – For example, use 0.0833 to represent 1" in decimal feet instead of 0.08.
Blocks should not be inserted on top of each other even if on different layers.
No drawing objects should remain on Layer 0.
Purge all drawings of empty, unused, or non-essential drawing data. This includes all unused layers, line types, blocks, fonts and entities. At the end of the project use “super purge” command: -purge
Audit all drawings and fix all errors.
Make sure the following variables are set correctly:
o LTSCALE = 1/3 o MSLTSCALE = 1
o PSLTSCALE= 1
All drawing objects except those schematic in nature shall be created or inserted at 1:1 in model space and on the correct coordinate system. Alternatively, technical schematic drawings may be drawn “not to scale.” Examples of technical schematics include:
Schedules
Riser diagrams
Schematic diagrams
Single line diagrams o This does not refer to drawings created during the schematic phase of a project.
Creating Details, Sections, Elevations, and Schematics When drafting details, sections, elevations, and schematics, the G-DETL, G-SECT, and G-ELEV layers should be used (See Appendix C, Drawing View Layer List section). These include a variety of line types and line weights. This convention greatly reduces the number of layers needed for these types of files.
Creating Blocks When creating blocks, the following guidelines should be followed:
Make sure the block does not already exist in a standards library.

Follow block naming convention described below.
Nested blocks are permitted but should be avoided whenever possible.
Create blocks on layer 0 (zero) with all properties BY LAYER so that the block inherits the properties of the layer on which it is inserted. If a block is complex enough to require multiple line weights or line styles, standard layers should be used, but use as few as possible.
Use logical insertion points such as the center of a circle or the lower-left corner of a square.
Blocks that contain a text variable should use an attribute. Attributes must use TCCD standard text properties.
Dynamic Blocks are preferred where a single block can replace numerous blocks of similar types or size variables.
Do not use the “TCCD” prefix when naming blocks as this is reserved for Tarrant County College District standard blocks and symbols.
Anny annotation and symbols blocks should be “Annotative”.
Use TCCD standard blocks whenever applicable.
TCCD Standard Block Naming TCCD standard block naming is similar to the NCS layer naming standard, which breaks up layer names into four or more field types. The TCCD block names are prefixed with “TCCD” and are named in accordance with the following convention:
TCCD BlockName = TCCD-Discipline-Major group-Minor group-Description_Identifier (The Minor group and the Identifier are optional) Examples:
TCCD-C-FIRE-HYDR – TCCD-Civil-Fire-Hydrant TCCD-E-CIRC-JBOX – TCCD-Electrical-Circuit-Junction Box Do not modify or redefine TCCD standard blocks and symbols! User created and project specific blocks will follow the same naming convention as above, except TCCD- prefix will be dropped (avoid anonymous blocks, such as *U29 or UNL468$54):
C-FIRE-HYDR –Civil-Fire-Hydrant
E-CIRC-JBOX –Electrical-Circuit-Junction Box
TCCD provides standard Title Blocks for all common sheet sizes. 24x36 vertical Title block is the TCCD preferred standard and should be used on all projects unless another size or orientation title block is required due to the nature of the project. Title blocks should be inserted as a block in paper space on layer G-ANNO-REFR.

The base point of the standard title block is the lower left corner of the invisible sheet boundary and the insertion point in paper space is 0, 0. The title block should default to this insertion point when inserted. Attributes may be edited upon insertion or with AutoCAD Sheet Set Manager. The advantage of using Sheet Set Manager is that attributes within the sheet can be labeled on all title blocks (as well as elsewhere in the sheet) simultaneously. The use of Sheet Set Manager is considered a TCCD best practice as it improves efficiency and reduces the possibility of errors associated with callout information. All applicable fields in the title block MUST be filled out. Project Number, Name, Sheet Title, and Sheet Number are defined in the Sheet Set Manager. Refer to Appendix K for detailed explanation of Title Block attribute data.
Cover Sheets for Consultants Block named TCCD-G-ANNO-TTBK-CVER_CONSULT.dwg is to be use by all the consultants generating drawing for TCCD projects. Project specific attributes must be populated. Space below the horizontal line is reserved for the use of consultants. It can be used for project renderings, images, or maps.

Every space in TCCD facility will have a room identifying tag on the drawings. TCCD-G-ANNO-ROOM-TAG block has been designed in such way as to capture critical information that TCCD staff will manage. All applicable fields of both visible and invisible attributes must be filled in for every space.
Space type definition is controlled and selected via a drop down view menu. For space usage definitions and typical room name abbreviations please refer to the Appendix H.
To establish TCCD brand and unified look of drawing set produced by the different consultants, TCCD requires that all consultants as well as in-house design teams use TCCD issued drawing titles. Drawing titles are set up in such way that allows for a total of (3) line titles. This option is controlled via attributes.

There are a number of additional typical blocks developed for use in TCCD drawings for all trades. This library will be continually evolved so please request the updated library before starting a new project. Refer to Appendix I for the additional block definitions.
When hatching, the following guidelines should be followed:
Hatching shall be drawn on layers with “PATT” as a minor or minor2 category.
Do not use polylines with increased width for hatching.
Do not use hatch patterns that are not AutoCAD standard or included in the hatch patterns set for the TCCD standard.
To reduce drawing size, it may make sense to only hatch certain portions of an area, such as hatching representative areas of a paving hatch for parking lot or a brick hatch for a wall elevation.
It is preferred for all hatching to be "associative" or "annotative" – both of these describe methods of producing hatch patterns in AutoCAD. Refer to the sections below for more information on these.
The hatch border should be placed on a "No Plot" layer.
Associative Hatch Patterns Use associative hatching if you want the hatch updated when you change the boundary.
Hatched areas created with the HATCH command are associative by default.
Set your variable HPASSOC to one (1). Hatch patterns and gradient fills are associated to the boundaries and update when the boundaries are changed.
Set your system variable HPGAPTOL to zero (0). Specifies the maximum gap (or opening) that is to be bridged when trying to form a closed hatch boundary.
After a hatch pattern is edited, it may need to be re-associated.

Annotative Hatch Patterns Use annotative hatching if you want the hatch scale to match the drawing scale and want the hatch to be associative. Instead of creating multiple annotations at different sizes and on separate layers, you can turn on the annotative property by object or by style, and set the annotation scale for layout or model viewports. The annotation scale controls the size of the annotative objects relative to the model geometry in the drawing.

External References (Xrefs) When working with Xrefs, the following guidelines should be observed:
All Xrefs should be set as "overlays" – do not “attach” or “bind”. Occasionally there are exceptions to this guideline in that it might be necessary to “attach” an Xref for a specific purpose.
Xrefs should never be exploded, redefined or modified, even with Refedit.
Xrefs should always be on the same coordinate system and at the same scale as the drawing they are referenced into.
Xrefs should always be on a TCCD standard layer for Xrefs. In most cases, all Xrefs can be placed on the standard “G-ANNO-REFR” layer. However, if Xrefs need to be on separate layers, additional layers may be created with a Minor 2 Category such as “G-ANNO-REFR-UTIL” for a utility drawing.
Always use relative file paths for Xrefs to ensure that character limits for the Xref path are not exceeded.
Do not exceed 15 Xrefs per file, unless approved by TCCD.
External Reference map must be provided for every project in a Microsoft Excel format for all drawings containing Xrefs. This file should follow appropriate naming conventions and is stored on a “3 – Misc” folder and described further in the Standards Manual.
Image Files Image files shall be treated similarly to Xrefs, except for the assigned layer, “G-ANNO-REFR-IMAG.

Following the cover sheet, sheets should be organized into subsets as per below image:
TCCD Sheet numbering Syntax follows NCS recommendations with some modification for the Facility Master Drawings and includes the following components:
The discipline designator, consisting of one alphabetical character and a hyphen or two alphabetical characters and a hyphen.
The sheet type designator, consisting of one numerical character.
The sheet sequence number, consisting of two numerical characters. Sheet numbering refers to the sheet designation labeled in a specified spot within the title block that uniquely identifies the sheet. Sheets are drawings that are part of the contract document set and the sheet number is therefore quite important for organizing the

drawing set and for referencing between drawings. An example of sheet numbering is shown below.
The syntax for assigning sheet numbers is shown below: Examples:
A-102 – Architectural Plan, Second Floor A-105 – Fifth Floor Architectural Master Plan S-220 – Structural Framing elevations P-602 – Plumbing Riser Diagrams Note the cover sheet does not have a Discipline Designator, or Sheet Type Designator. The sheet number is simply “Cover” or no designation at all. Each section of the Sheet Numbering Syntax, specifically Discipline Designator and Sheet Sequence Designator are explained in the sub-sections below.
Discipline Designator The Discipline Designator creates the primary “sort order” of the drawing set. Sheets are grouped by discipline and disciplines are ordered in a logical fashion, according to NCS.

Discipline Designator Table in order of drawing set, rather than alphabetical: The primary organizer of drawing sets is disciplines. The order that the disciplines appear in the drawing set generally follows the order in which a project is built, starting with site related disciplines (geotechnical, civil, landscape, hazardous materials, etc.), then to overall building/facility related disciplines (architectural, structural, interiors), then to building/facility systems (mechanical, electrical, plumbing, etc.), and finally to construction and maintenance with shop drawings and operations.
Sheet Type Designator The Sheet Type Designator is a single digit that indicates the “type” of information presented on the sheet such as plan, elevation, schedule, etc. If multiple types of information are presented on a sheet, select the dominant one from this table. The practice of putting multiple information types on a sheet is encouraged to avoid creating a separate sheet for a minimal amount of information.

Mixed Sheet Types It is common for elements of sheets to be of mixed “Sheet Types.” For example, details or elevations are often included as part of plan sheets. This is perfectly acceptable as long as:
The primary element of the sheet controls the Sheet Type Designator
The sheet title in the title block is descriptive enough to indicate the nature of the drawing, such as “Storm Drainage Plan and Details” for a storm drainage plans that includes details.
Sheet Sequence Designator Because of the wide variety of projects within TCCD, the practice of using the Sheet Sequence Designator is thoroughly controlled by the standard. Sheet Number Blocking – For large facility drawing sets such as at TCCD, it is useful to do Sheet Number Blocking, which may be defined as using the Sheet Sequence Designator to block out ranges for different types of drawings within a Sheet Type. A master floor plan example is grouping Plans (Sheet Type 1) by designating that sheet numbers in the range A-100 to A-109 are reserved for existing condition plans, A-110 to A-119 are reserved for
A-102 (uses a “Plan” sheet type designator)

reflected ceiling plans, sheet numbers in the range A-120 to A-129 are reserved for finish plans, etc. Gaps in Sheet Sequence Number – Using the above approach to group types of sheets will create gaps between sheet sequence numbers. However, if TCCD standard is properly followed, there should be very few sheets that need renumbering when sheets are added or deleted. This is critical because most revision comments are based on sheet number. It is not necessary to designate sheet numbers as “Not Used” on the cover sheet. As long as all sheets are listed on the cover sheet, the order of the plan set should be obvious. 00 vs. 01 – The use of Sheet Sequence Designator ending in zero (0), such as A-100, A-110, A-120 etc. should be reserved for cases where a general or overall sheet, like a key plan or notes, precedes a series of other sheets. A master plan example is an Overall Campus Plan (A-110) preceding 5 sheets that are separate building plans on that campus (A-111 to A-115). Otherwise, 01 should be the first Sheet Sequence Designator.
Sheet Set Sequencing Sheet sets are ordered first by the Discipline Designator (see the Discipline Designator table for order) and then by the three digit number that is composed of the Sheet Type Designator and Sheet Sequence Designator. When sheets are placed in numerical order, this numbering system will group sheets by Sheet Type such as Cover Sheet, General, Plans, Elevations, Sections, etc. The Discipline Designator Table is taken directly from NCS (with the exception of "U" for Site Utilities and “K” for Space Tracking) and lays out the order that discipline specific drawings should fall within a plan set.
Sheet Index Lists CAD designers and technicians must recognize that projects have team members without access to CAD, but who routinely review, utilize, and/or provide design input to sheets in the project sheet set. It is considered a “best practice” to maintain a sheet list outside of the CAD environment that reflects the sheets for all disciplines (existing and planned) in the CAD environment. This is the function of the Master Sheet Index (MSI). All facility drawings as well as new projects with contract drawings are advised to maintain a Master Sheet Index (MSI) that is stored under the “3 – Misc” folder of the project folder. The filename should be G-SH-MSHT_INDEX.xlsx. In the case of multiple or distinct final packages, the description field of the filename can be modified to reflect the respective package. The MSI should be maintained by the project team member responsible of the CAD drawings on the project (project CAD coordinator).
Minimum Required Master Sheet Index Info All master sheet indexes must at minimum, include the following information:
Header information:
o Project Number, Name, and Manager
o Campus
o Building Name and ID
o File Name

o Sheet Index
Sheet Numbers
Sheet Titles o Completion date (must be included once issued for construction, if applicable) o Comment column for coordination notes and to indicate ‘placeholder’ drawings (i.e. drawings that are planned but not yet assembled)
Using the MSI in the Plan Sets The other function of the MSI is to be used / shown as the sheet index in the plans. This can be accomplished by Data Linking the MSI into the plan set. Sheet Index will also maintain a dynamic link between the plans and the MSI. When using the Sheet Set Manager (SSM) to manage your drawings within the plan set, replicate the MSI as closely as possible. This also facilitates the use of just one MSI and the ability to have it displayed in multiple places.

An AutoCAD file is an electronic file that represents one or more sheets in the project drawing set (sheet files), “component" drawings, or data files (model files, schedule files,
details files) that are referenced into the sheet files. TCCD file structure is organized to facilitate proper management of the Master Facility Drawings and keep them separated from the on-going projects. Later described workflow allows for efficient updates to facility master drawings based on any completed projects. Folder structure screen shots shown throughout this section indicate the standard file management practices, but do not show an entire folder structure.
0 – Master Facility Drawings This is where the Master Facility drawings will be stored. Drawings will be in a read only format (write-protected) and used as a reference and for information reporting purposes.
1 – Current Projects – In-House Contains active project drawings generated at TCCD by TCCD design team.
2 – Current Projects – Consultants Contains active project drawings generated by the outside consultant teams.
3 – Completed Projects – Add To Masters Contains complete project close-out documentation, including final as-built drawings, generated by either TCCD in-house teams or outside consultants; that are to be incorporated into the Master Facility Drawings and databased for archival information.
4 – Record Drawings Contains all of the existing drawings TCCD has for all facilities and sites in DWG, PDF, TIFF, JPG and other formats. These files are databased and searchable. They should only be used as historical reference documents.

XXXX -BUILDING ID MASTER_SETDESCRIPTION
Sheet File is NCS term for the electronic files that represent the sheets that will be printed as part of your project drawing set, or contract drawings. Sheet files generally include a sheet border in paper space, various paper space symbols and annotations, and typically include viewports to drawing information in model space where drawing objects and one or more model files may reside. This folder should contain only sheet files that make up the sheet set; however Sheet Set Manager (SSM) .DST files, should reside here as well.
Creating Subfolders under Sheet Files As a general rule, subfolders should only be created to segregate drawings by discipline as is shown above. For Current Projects, the discipline subfolders can be omitted if project size and scope does not warrant discipline subfolders.
Using Multiple Sheet Tabs within Sheet Files AutoCAD allows multiple sheets in the sheet set to be represented by a single sheet file containing multiple sheet tabs. The TCCD standard requires having one sheet tab per sheet file.
Sheet Set Manager File Names Due to the probability of having multiple sheet sets open from different projects at the same time, the following naming convention must be used. Facility Master Drawings:
Examples: TRWF-MASTER_SET.dst SACT-MASTER_SET.dst All Other Projects:
Examples: 20028-TRTR_MATH_EMPORIUM.dst 20154-TR_FIRE_PANEL_UPGRADES.dst

Sheet File Naming Convention Sheet file naming convention differs from the actual Sheet Numbering convention and includes Building ID prefix for all sheet files (and an “M” designator for Facility Master Drawings only). Different projects can have the same sheet number (such as Architectural 2nd floor plan: A-102), but it is critical that there is minimal file name duplication to avoid accidental file overrides when moving or copying files between projects. Sheet files shall be named in accordance with the following conventions. Facility Master Drawings:
Examples: TRWF_AM-001.dwg SACT_MM-104.dwg Sheet files naming convention differs from the actual Sheet Numbering convention and includes Building ID prefix All Other Projects:
Examples: TRWF_A-001.dwg SACT_M-104.dwg
The “2 – Model Files” folder includes all file types used to assemble the sheet files that make up the project drawing set. This includes model files, detail files, image files, and schedule / table files. All files in the “2 – Model Files” folder should be current files that are referenced or linked into sheet files. Do not "clutter" the “2 – Model Files” folder with different versions of files as this ultimately leads to confusion and errors.
Model Files Naming Convention Model files are drawings that form the "base" drawings of the project – both existing and proposed representations of the project (above ground and underground site, building layouts, etc.). Detail files, image files, and schedule / table files are another type of model file. Image files are typically TIF, JPG, etc. that are referenced into the drawings. Detail files in this context include details, sections, small plans and elevations and anything else that would fall in the DT model file type. Schedules and tables are essentially the same thing – tabular representations of detailed information, typically created in Excel and linked into the drawing.

Publish When drawings are published, such as to a printer/plotter “hardcopy” or DWF/PDF/PLT “digital” format, they represent the status of the drawing at the time they are published, essentially creating a picture or snapshot in time of a drawing. The published drawing loses continuity with the active drawing immediately after it is published as it has no ability to keep pace with the changes in the drawings, until the next time it is published. To the design team, the value has a short time span, but to the client or a reviewing agency, it is valuable because it is a snapshot at a particular milestone on a project. To that end, the Publish folder is intended as a temporary holding location for published drawings in a DWF, or PDF format. The published drawings either proceed to the printer/plotter for “hardcopy” distribution or to the Deliverables folder as part of a “digital” deliverable package to the client. In either case, the Publish folder should be cleared of all files after the project is complete.
Support Files Support files are all the files that are created and saved over the course of a project that neither get submitted to a client nor referenced to a file. This folder is also to store data as it is being assembled for use in the “Model Files”, “Sheet Files”, and Misc” folders (the folders containing the drawings that make up the project drawing set). Use of this folder will prevent two things that often affect project AutoCAD work from occurring:
It will keep the "production folders" (Model Files, Sheet Files, and Misc) clear of multiple versions and "junk" files, which often lead to confusion and misuse of files.
It provides a specific location to store temporary files so they are not stored on local drives or in other network folders. When folders and files in the “Support Files” folder are no longer needed, they should be deleted.
Survey The Survey folders contain Field Survey related files generated by TCCD staff and/ or outside consultants. This folder will contain documents such as field surveys for any trade, civil/ site survey information, raw point clouds generated via 3D scanner, photos, etc. Users can generate sub-folders as needed to organize different types of field information, but should use logical and easy to follow names (such as “Photos”, “Point Clouds”, “Field Notes”, etc.)

Projects developed by outside consultants will follow the same file storage format as the in-house projects. Any documentation received from the consultants will be placed in an appropriate folder for the project duration. Final close-out documents will be databased, incorporated into the Master Drawings and moved to the Record Drawings folder. It is the responsibility of TCCD consultants to turn over their project documentation in an appropriate format and file organization.
This is a temporary file storage location for recently complete projects. It contains complete project close-out documentation, including final as-built drawings, generated by either TCCD in-house teams or outside consultants. Once the complete project information is incorporated into the Master Facility Drawings and the rest of the documents are databased, the entire project MUST be moved to “4 – Record Drawings” folder. Maintenance of this folder should take place bi-annually.
Contains all of the existing drawings TCCD has for all facilities and sites in DWG, PDF, TIFF, JPG and other formats. These files have been sorted for duplicates, organized, databased and indexed to be searchable based on a number of project parameters. They should only be used as a historical reference document and are in a “Read-Only” format.

All employees working on TCCD projects are expected to take measures to keep project folders "clean." The project CAD lead is responsible for occasionally auditing the CAD folder to ensure that this standard is being followed and that good file management practice is being employed. A few things to keep in mind: • Keep folders free of “junk”, “old”, or “erase me” files.
The “Model Files” folder and the “Sheet Files” folder should only contain current files that can be reliably used on the project. There should be no confusion as to file "versioning" because multiple versions should not exist in these folders. Use the “Support Files” folder as described herein for versioning, assembly and "experimenting", and short term archiving.
All drawings shall be purged of empty, unused, or non-essential drawing data. This includes layers, linetypes, blocks, fonts, and entities.
The following diagram is shown to depict the relationships between different file types, the standard TCCD AutoCAD folder structure, and the project drawing set.

Electronic AutoCAD Files, herein simply referred to as “AutoCAD files” are defined as AutoCAD drawings and include any other files referenced by the AutoCAD drawings or included for reference.
1. Unless electronic AutoCAD file distribution is explicitly defined by the contract, no AutoCAD files may be distributed to outside parties unless the policy defined herein is followed. 2. All electronic file transfers shall include a copy of the standard TCCD Terms of Electronic File Transfer (TOFT) with the transmittal. This is available on the TCCD web page (see Appendix J for a standard TOFT Form). 3. When sending the files by email or notifying the recipient of a download site by email include the TOFT at the bottom of the email or as an attachment in PDF format. 4. The electronic files should be prepared by transmittal such that all necessary data files, font files, plot settings, x-refs, etc. are included and appropriately structured. The transmittal should include adequate documentation to explain the contents of the electronic files. The standard policy for preparation of electronic documents for transmittal is to utilize the built-in “e-transmit” feature.

When the term "plot file" is used herein, it refers to the file that is created from a drawing file (.DWG, .DGN, PDF, etc.) that will be sent to a plotter to produce a paper copy of the drawing file. Plot File in this standard does not refer to a .PLT file, which is a specific type of plot file but is often called a "plot file" The following three (3) categories of plot files are defined for the purposes of describing the standards for creating, naming, and organizing plot files: 1. Check Plots - are run for AutoCAD operator review, informal review or for other team members. Check plots are not associated with a formal milestone review or review submittal. 2. Milestone Review Plots - are run for established project milestones or internal review prior to project milestones. Project milestones include review milestones but not the final deliverable and are typically submitted to clients, client representatives, or review agencies. Milestone review plots are often submitted to obtain permits or approvals. 3. Final Deliverable Plots - are run for submittal of final drawings to clients, client representatives, or review agencies. Final Deliverables include: a. Bid Sets b. Construction Sets c. Supplemental Drawings d. Record Drawings
Plot File Formats The most common types of plot files are Design Web Format (DWF) and Portable Document Format (PDF) files. The TCCD standard is to produce plot files in PDF format whenever possible. While the requirements for naming and storing the two categories of plot files described above differ, all should be produced in the same plot file format as the final deliverable will be plotted in (preferably PDF) to ensure that drawings plotted for review are consistent with final deliverables.
All plot files, whether used for checking a drawing/set or a deliverable drawing/set, shall be kept in the "Publish" folder. The individual plot files
64
Tarrant County College District AutoCAD Standards Manual
Rev. 01 – April 21, 2016
Printed Copies Uncontrolled 63
shall match the name of the plotted drawing. For deliverable sets, a merged single-page PDF version of the sets shall be created and moved under the "Deliverables" folder. This way the project team has access to the package, as delivered, and no duplicate plot files exist under the “Publish” folder. The relationship between the “Publish” folder and the “Deliverables” folder is illustrated in the preceding image.
In order to produce consistent plots, the selections shown below should be made when plotting sheet files. Areas circled in blue will vary by project. • Page setup – varies by project depending on the sheet size. • Printer/plotter – use AutoCAD built–in PDF generator “DWG to PDF” • Paper size – varies by project depending on the sheet size. • Plot area – Plot to extents when using the standard title blocks. There should be nothing outside the “no plot” border of the title block. • Plot offset – Center the plot when using the standard title blocks. Plot offset should indicate small positive values. • Plot Scale – Always plot 1:1 when using the standard title blocks. Select “Scale lineweights” option when producing reduced size prints. • Plot Style Table – Should always be set to TCCD_Standard.ctb

TCCD will hold the latest Master Facility Drawings based on the Electronic File Management procedures outlined in the preceding sections. No design work will be done on the Master Drawings directly. For new work, copies of the Master Drawings will be acquired by the project manager to use as a reference.
Following is the folder structure for managing files for new work;
On TCCD Server
0 - Master Facility Drawings: This is where all Facility Master Plans are stored.
1 - Current Projects – In House: The TCCD Project Manager obtains a copy of the relative Master Drawings for use by the in-house design staff. Progress drawings are stored in this folder.
2 - Current Projects – Consultants: The TCCD Project Manager obtains a copy of the relative Master Drawings for use by the outside Consultants. Progress drawings are stored in this folder.
3 - Completed Projects – Add to Masters: When the project is complete, the TCCD Project Manager moves the final project files to this folder. A copy of these files as well as a copy of the relevant Master Drawings is also placed on Buzzsaw to the same named folder. B-CAD will use these for updating the Master Plans.

The Drawing View field code DETL is specialized code for layers that are organized primarily by drawing type (Detail in this case), rather than by major building system.
Number designators 1 to 9 indicate color (and thus lineweight) assignments to the layers: Color 1 (the darkest lineweight to Color 9 (the lightest lineweight). See Section "4.9 Color" in the TCCD AutoCAD Standards Manual for additional Lineweight information. Use linetype override in properties as needed for hidden, center and other line types needed.
The Drawing View field codes are specialized codes for layers that are organized primarily by drawing type, rather than by major building system. The field codes DETL, ELEV, and SECT may also be used as Minor Group field codes to modify a major building system.⍁ Symbol in the layer name can be substituted for any discipline (A - for Architectural, U - for Utilities, etc.).

ANNOTATION LAYER LIST
Annotation consists of text, dimensions, notes, sheet borders, detail references and other elements on CAD drawings that do not represent physical aspects of a building. Use of the Major Group ANNO allows all annotation to be placed in a defined group of layers.Discipline G designates "General" indicating that theses layers are the same to all disciplines. Some discipline specific annotation layers are defined under those disciplines.
