1 Telecommunications Distribution Design Guide [ Version 8 ]

Document Intent

Please be advised that this document is intended to serve only the purposes of GSA. It does not apply to non-GSA tenants.

The requirements described in this document apply only to spaces and systems for which the GSA IT has stewardship. Some departments within GSA may have their own telecommunications standards. The Designer shall communicate with each GSA department that will occupy space in the building to obtain their potentially unique requirements for telecommunications infrastructure for spaces and systems under their stewardship.

Other non-GSA tenants may also occupy space in a building. The Designer shall inquire whether a facility will serve non-GSA tenants, and if so will work with the GSA PBS PM to obtain tenant-specific telecommunications infrastructure requirements for non-GSA tenants.

Other building tenants (both within GSA and non-GSA) may choose to adopt these standards for their purposes on a given project. However, this document does not require that they do so.

This document describes contractually binding requirements with which technology infrastructure designers, architects, engineers, and design-build contractors/installers must comply.

9 Telecommunications Distribution Design Guide [ Version 8 ]

Preface

A. The Telecommunications Distribution Design Guide (TDDG) is written to communicate the requirements of U.S. General Services Administration (GSA) for the design and installation of telecommunications distribution systems at GSA facilities.

• The TDDG is written for the following audiences:

+ Architects, Engineers, and Designers who are responsible for the design of new or remodeled facilities for GSA, where telecommunications infrastructure currently exists or will be installed.

+ Telecommunications contractors (and other low voltage contractors) installing telecommunications infrastructure at GSA facilities.

+ GSA personnel who are involved in the construction of projects with technology infrastructure, regardless of the size or scope. This may include personnel from GSA IT, GSA FAS, and GSA PBS, or their representatives.

B. Telecommunications distribution systems designed for GSA are expected to support and integrate telecommunications of voice, data, video, and other low voltage systems with common media; for example, fiber optic and unshielded twisted pair (UTP) copper cable.

C. Telecommunications distribution designers shall be responsible to apply the guidelines, instructions, and requirements in this document while designing telecommunications distribution infrastructure at GSA facilities.

1Preface

10 Telecommunications Distribution Design Guide [ Version 8 ]

D. It is the responsibility of telecommunications distribution designers to coordinate with the other designers on a project (architectural, electrical, mechanical, etc.) to determine whether other systems are both compatible with and complementary to the telecommunications cabling system. It is critical to coordinate between disciplines during the design phase of a project, rather than making adjustments in the field during construction.

E. Contractors and cabling installers involved in projects without a formal engineering and design process shall be fluent with and adhere to the requirements of this document in the course of their work at GSA facilities.

F. This document was prepared by GSA IT. It is updated periodically by GSA IT to reflect changes in technology and policy. The revision history is as follows:

August 9, 2010 Originally published

September 30, 2010 Updated

July 27, 2011 Updated

April 16, 2014 Updated, Version 7 published

August 6, 2016 Updated, Version 8 published

G. For inquiries about this document, please email infrastructure@gsa.gov.

1.1 Low Voltage Systems

A. Wherever practical, telecommunications pathway and cabling systems designed for GSA facilities are expected to support and integrate with the complete set of building automation systems and other low voltage systems that convey information and operate facilities. Telecommunications infrastructure shall be designed in accordance with the requirements in ANSI/TIA/EIA 862-A – Building Automation Systems Cabling Standard, and the requirements in this document, to support the Ethernet telecommunications channels on low voltage devices.

Throughout this document, references to “low voltage systems” shall include those referenced in ANSI/TIA/EIA 862-A, and shall be subject to specific requirements in that standard and as discussed below.

B. Wherever possible, cabling supporting building automation systems and other low voltage systems shall be either 24 AWG UTP copper cable (Category 5e-rated or better) or 50/125 micron multimode fiber optic cable. Backbone cabling is permitted to be shared among systems; however, horizontal cabling serving these systems shall be dedicated to each system.

C. The common inside plant (ISP) telecommunications pathway is intended for shared use by these systems.

1 Preface

11 Telecommunications Distribution Design Guide [ Version 8 ]

D. The following is a non-exclusive list of building automation systems and other low voltage systems that use telecommunications infrastructure. Other similar systems may also require the support of telecommunications infrastructure.

• Voice-Over-IP (VOIP) Telephone Systems • Video Systems (Digital)

• Data Networks (wired and wireless) • Fire Alarm Systems

• Building Automation Systems • Security Systems

• Video Surveillance Systems (IP-based) o Access Control Systems

• Energy Management Systems o Alarm Systems

• Environmental Control Systems • PLC Control Systems

E. Inside plant telecommunications infrastructure intended to support Ethernet telecommunications (or other similar protocols for security and fire alarm systems) shall be designed in accordance with the inside plant telecommunications infrastructure requirements in this document. However, due to the critical nature of these systems, inside plant pathway and cabling serving these systems shall typically homerun to a Mechanical Room or other Low Voltage Electronics Room rather than to a common shared telecommunications room.

F. Where low voltage systems require different media (other than fiber optic cabling and 24 AWG UTP), the systems shall be designed to comply with the pathway and space requirements of this document wherever practical.

G. The Designer shall design pathways and cabling to serve these systems, in cooperation with the other design disciplines on a project.

1.2 Outside Plant Infrastructure

A. The majority of GSA facilities are stand-alone buildings that are not networked directly with other buildings in a campus-like environment. Interconnections between buildings are typically accomplished using third-party service providers.

B. The installation of GSA-owned outside plant telecommunications infrastructure is rare. In such cases the Designer shall design outside plant spaces, pathways and cabling to meet the requirements of the project, under the direction of GSA IT IT-Specialists.

C. Where outside plant telecommunications infrastructure is required for a project, the services of an engineering firm specializing in OSP will be necessary to design standards-compliant underground ductbanks, maintenance holes, aerial pathways, and outdoor-rated cabling.

12 Telecommunications Distribution Design Guide [ Version 8 ]

1.3 Document Context

A. GSA has standardized on the ANSI/TIA/EIA – Commercial Building

Telecommunications Standards series and has adopted the following BICSI1 design guide documents as the basis for telecommunications distribution design in GSA facilities:

• Telecommunications Distribution Methods Manual (TDMM), 13th Edition

• Information Transport Systems Installation Methods Manual (ITSIMM) The GSA TDDG is the guide to the application of the ANSI/TIA/EIA Standards, the BICSI TDMM, the BICSI OSP Design Reference Manual (OSPDRM), and the BICSI ITSIMM to the unique circumstances present in GSA facilities and projects. See Figure 1 below for further information.

B. The TDDG is intended to be used in conjunction with the TDMM to reinforce selected TDMM content. It is also used to highlight any restrictions and/or limitations on TDMM content to meet the specific requirements of GSA facilities.

The TDDG is not intended to detract from or replace the TDMM.

C. The TDDG is not intended to serve as a master specification nor for stand-alone use on design-build projects. This document is a guide for making standards-compliant design decisions that will in due course be reflected in a project specification.

D. In addition to the telecommunications specifications for a project, plan drawings, schematic diagrams, and details shall also be produced by the Designer, in conformity with the guidelines contained in the TDDG.

E. The following diagram (Figure 1) depicts the relationships between the ANSI/TIA/EIA Standards, the BICSI Design Guidelines, the GSA TDDG, and the project-specific Construction Documents. Telecommunications distribution infrastructure at GSA facilities shall be designed based on the BICSI design guidelines (the TDMM, the OSPDRM, and the ITSIMM) and compliant with the ANSI/TIA/EIA Standards as applied by and illustrated in the GSA TDDG.

1The BICSI TDMM is widely considered to be the industry reference text for the design of standards-compliant telecommunications distribution systems (see http://www.bicsi.org/manuals.htm ). BICSI, 8610 Hidden River Pkwy, Tampa, FL 33637-1000 USA; 1-800-242-7405; http://www.bicsi.org

13 Telecommunications Distribution Design Guide [ Version 8 ]

FIGURE 1: THE DESIGN PROCESS

F. The TDDG provides guidelines for telecommunications distribution system design for use within a building for all telecommunications, low voltage, and signal systems as related to:

• Telecommunications Spaces – Entrance facilities, equipment rooms, and telecommunications rooms

• Intra-building Backbone Distribution – Pathway and raceway requirements, telecommunications media requirements

• Horizontal Distribution – Pathway and raceway requirements, telecommunications and low voltage media requirements, requirements for special work areas

G. This document provides directions for making standards-compliant design decisions that will ultimately be reflected in Construction Documents. The Construction Documents for a project will be comprised of drawings and a specification that properly incorporates telecommunications infrastructure within

14 Telecommunications Distribution Design Guide [ Version 8 ] a project. The TDDG shall be used to guide the development of content in project-specific Drawings Specifications.

H. Adherence to and compliance with the latest versions and addenda of the codes, standards, and industry practices listed below, along with the GSA requirements contained in this document, is mandatory. Please note that when new versions of industry standards are released (independent of GSA’s actions), conflicts between the TDDG and the new standards version may result. It will require some time for GSA IT to review the new standards and update the TDDG.

Therefore, when conflicts are discovered, please seek guidance from the GSA IT

ITS.

Edition) J. Requests to deviate from the GSA requirements may be submitted on a case-by-case basis. No deviation from the requirements of the National Electrical Code

15 Telecommunications Distribution Design Guide [ Version 8 ] will be allowed. For further information regarding codes and standards, please refer to Appendix A in the BICSI TDMM as well as the BICSI OSPDRM Bibliography.

K. Where conflicts may arise between industry standards, Codes, GSA’s standards, and the requirements of the local Authority Having Jurisdiction, the most stringent requirements shall apply.

L. The requirements contained in the TDDG are considered to be in addition to the requirements in the Facilities Standards for the Public Buildings Service (PBS P100-2016). Where a specific requirement differs, the conflict shall be brought to the attention of the GSA PBS Project Manager for resolution.

• While the entire P100-2016 document has important content, Sections 6.5.8 through 6.5.11 contain content specifically related to telecommunications.

1.4 Document Structure

The TDDG is organized in six sections:

1. Preface

2. GSA Telecommunications Policies

3. Project Procedures

4. Design Criteria

5. Construction Document Content

6. Appendices

A. The Preface (this section) describes this document, its intent, and its relationship to industry standards, practices and the various audiences affected by the document. It also describes how to use this document.

B. The GSA Telecommunications Policies section applies specifically to GSA personnel. It describes internal GSA telecommunications policies, requirements, standard practices, and processes for designing, installing, and operating telecommunications infrastructure. GSA personnel should also be aware of the instructions, requirements, and guidelines for Designers contained in the other sections of this document, with respect to their application on both large-scale telecommunications distribution projects and small-scale “moves/adds/changes” (MAC) projects. In addition, these requirements apply to in-house operations and maintenance of existing telecommunications distribution systems.

C. The Project Procedures section describes the required qualifications for telecommunications Designers, as well as the procedures that Designers must follow when working on telecommunications infrastructure projects at GSA facilities. It includes activities that are required throughout the project as well as phase-specific requirements.

16 Telecommunications Distribution Design Guide [ Version 8 ]

D. The Design Criteria section serves two purposes. The first is to describe the general requirements for GSA telecommunications infrastructure, along with the typical features required for different categories of building spaces and construction types. The second purpose is to place limitations on the materials and methods described in the BICSI TDMM. While the TDMM describes many materials and methods that are generally accepted in the industry for providing telecommunications infrastructure, GSA facilities have some unique characteristics that impose limitations on some of the materials and methods that otherwise might be acceptable. Some of the practices discussed in the TDMM are expressly prohibited in GSA facilities.

Generally speaking, if the BICSI TDMM does not describe a particular material or method for use with telecommunications distribution infrastructure, it will not be allowed for GSA facilities unless specifically requested and pre-approved. In addition, the GSA TDDG places further restrictions on the use of some materials and methods that the BICSI design guidelines support.

E. The Construction Document Content section defines the minimum level of detail that GSA requires to be present in the telecommunications portion of the Construction Documents for a project. In this section, the required types of details, as well as the content in the details, are both described. This section also briefly describes the specifications that are required for a project.

F. The Appendices section provides example forms and diagrams that are required for GSA telecommunications infrastructure designs.

1.5 Construction Type

For the purposes of this document, construction projects are categorized by the extent of the construction work, as follows:

Construction Type Definition New Construction A new building Modernization An existing building undergoing extensive remodeling, frequently including reallocation of internal spaces Minor Remodel (workspace remodel)

An existing building undergoing adjustments to office/work spaces. The project typically does not include changes to building systems (HVAC, electrical, etc.).

Telecommunications-only Projects involving minor remodeling to create telecommunications spaces and the installation of telecommunications infrastructure

Moves, Adds, and Changes

Projects involving very limited adjustments to the telecommunications infrastructure

Historical Building Remodel

Changes made to buildings that are designated as historical properties.

17 Telecommunications Distribution Design Guide [ Version 8 ]

Unless otherwise stated, the guidelines defined in the TDDG apply to all five types of construction and to areas that GSA occupies within GSA-owned and leased facilities.

Historical Building Remodel projects will qualify as multiple construction types, for example:

• Historical Building Remodel + Modernization

• Historical Building Remodel + Minor Remodel

• Historical Building Remodel + Telecommunications-only The Designer shall assume that adherence is required to BICSI guidelines, referenced industry standards, and the TDDG (unless specifically indicated otherwise) for all facility types and for all extents-of-construction. Where exceptions are permitted, this document will specifically highlight the construction type where GSA’s requirements may differ from generally applicable practices and standards.

Adherence to applicable code is always required.

1.6 Building Types

The requirements described in this document apply to all building types. Where specifically noted for Warehousing/Stores facilities, some of the requirements may be relaxed.

1.7 Tenant Specific Requirements

The requirements described in this document apply only to spaces and systems for which the GSA IT has stewardship. Some departments within GSA may have their own telecommunications standards. The Designer shall communicate with each GSA department that will occupy space in the building to request and receive the requirements for telecommunications infrastructure in spaces and for systems under their stewardship.

Other non-GSA tenants may also occupy space in a building. The Designer shall inquire whether a facility will serve non-GSA tenants, and if so, shall work with the GSA PBS PM to obtain tenant-specific telecommunications infrastructure requirements for non- GSA tenants.

18 Telecommunications Distribution Design Guide [ Version 8 ]

1.8 GSA Departments

The following is a partial list of the departments within the General Services Administration (GSA) with which the Designer may be required to communicate and for whom telecommunications infrastructure may need to be designed:

• Office of the Chief Information Officer (GSA IT)

• Federal Acquisition Services (FAS)

• Public Building Services (PBS)

• Inspector General (IG)

• Office of General Counsel (OGC)

1.9 GSA Personnel

The following is a list of the GSA personnel who have authority over or responsibility for the telecommunications infrastructure in GSA facilities:

A. GSA PBS PM: Public Building Services Project Manager

• Responsible for the overall project, as it relates to the structure and serviceability of the building as a whole.

• Authorized to make final decisions for project-related issues related to the structure and serviceability of the building as a whole.

B. GSA PBS Building Manager:

• Responsible for the operation and maintenance of an existing building.

• The Designer may need to obtain as-built information from this individual regarding an existing building that will be remodeled or will receive new telecommunications infrastructure.

C. GSA IT ITS: GSA IT Information Technology Specialist

• Assigned on a project-by-project basis.

• Serves as the local IT specialist, having familiarity with the building, its resources, history, and operations.

D. GSA IT Tech PM: GSA IT Technology Project Manager

• Serves as the Designer’s main point of contact within GSA for telecommunications infrastructure guidance.

• Responsible for the telecommunications aspects of a project.

• Authorized to interpret the TDDG and to make decisions affecting the telecommunications infrastructure on a project.

• Coordinates with the GSA IT ITS infrastructure-related communication on capital projects.

19 Telecommunications Distribution Design Guide [ Version 8 ]

• Ensures that relevant GSA management and specialized technical staff are kept informed and involved in all telecommunications-related aspects of a project (design, construction, support, and maintenance).

• Ensures that the installed telecommunications infrastructure meets GSA standards and that the requirements of the TDDG are enforced.

E. GSA IT TD: GSA IT Telecommunications Designer

• Designs smaller telecommunications projects without the involvement of a consultant.

F. GSA Network Operations Branch Manager:

• Responsible to participate in the specification process (types, quantities, styles, makes-and-models) for network electronics and wireless networking required for internal GSA operations. This in turn will guide the decisions affecting the telecommunications infrastructure that will be required for specific application objectives. Quantity, type (pizza box, chassis switch), WAPs, style, make/model, etc. Aids in the design process to help create a cooperative infrastructure.

G. GSA Circuits Management Branch:

• Responsible to participate in the specification process (types, quantities, bandwidths, protocols) for wide area network (WAN) circuits required for internal GSA operations. This in turn will influence the network electronics specifications and will guide the decisions affecting the telecommunications infrastructure that will be required for specific application objectives.

1.10 Key Terms and Abbreviations

The TDDG uses many terms and abbreviations that are common in the telecommunications industry. While a glossary is included in Appendix 6.8 at the end of this document, please refer also to the Glossary in the BICSI TDMM for further information.

GSA Telecommunications Policies

This section describes internal GSA telecommunications policies, requirements, standard practices, and processes associated with designing, installing, maintaining, and operating telecommunications infrastructure. It is directed toward an audience of GSA personnel, including GSA IT personnel, PBS personnel, building maintenance personnel, and any others that may be involved in these activities at a GSA facility.

A. GSA personnel designing telecommunications infrastructure for GSA facilities shall follow the requirements in this document.

B. Input from the GSA IT Tech PM must be incorporated when developing the initial and ongoing construction schedules. This input is especially important when an early or phased turn-up of buildings is required, but is also vital for the initial startup of a new facility. The telecommunications rooms, Regional Information Centers, backbone pathways and cabling are all critical path items required for bringing buildings online within schedule.

C. Management of GSA’s Enterprise Network is the responsibility of the GSA IT Network Operations (NetOps) personnel, who cooperate in the specification process (types, quantities, styles, makes-and-models) for network electronics and wireless networking required for internal GSA operations at all GSA facilities.

NetOps works in conjunction with the Circuits Management Branch.

• At some GSA facilities, network documentation does not exist, is incomplete, or has not yet been updated to reflect recent changes. While GSA IT is currently working to improve the library of network documentation at each

2GSA Telecommunications Policies

22 Telecommunications Distribution Design Guide [ Version 8 ] facility, anyone relying upon this documentation for a project shall be responsible to verify that it is sufficiently accurate for their purposes.

• When using GSA IT’s existing network documentation for a new project, there is no guarantee that the documentation will (in its current condition) be suitable for that project. Users of GSA IT network documentation shall be responsible to investigate and update the documentation to meet their needs.

Project Managers shall include scope in their projects to prepare or update the documentation to meet the needs of their projects.

D. GSA’s GSA IT Information Technology Specialists are responsible for the installation and support of LAN hardware, data telecommunications, and VOIP network systems, as well as certain enterprise network hardware and software.

E. The responsibility for provision and procurement of IT services, hardware, software, and related products is project-dependent. The responsible Department or Division will be accountable for ensuring that the procurements meet GSA technology standards and that the procurement process is conducted in compliance with federal procurement guidelines, GSA policy, delegated authority, and statutory requirements. The Designer shall inquire on each project to determine who has this responsibility.

2.1 GSA Personnel

2.1.1 GSA Personnel Installations

A. GSA personnel (or representatives) who install telecommunications pathway and cabling infrastructure at GSA facilities must be familiar with the requirements of this document. They should also have a current copy of, be familiar with, and adhere to the guidelines in the BICSI TDMM and this document.

B. Telecommunications pathway work shall be done in accordance with the requirements of the NEC. Prior to constructing telecommunications pathways, a Registered Communications Distribution Designer (RCDD) shall be contracted to prepare drawings and specifications for the project. The RCDD shall also be contracted to periodically observe the work while in progress and upon completion, providing written observation reports following each visit. The RCDD shall also be contracted to produce as-built drawings bearing the RCDD’s stamp and signature. (For more information, see Section 2.7.7 – Telecommunications Administration, below.) GSA’s objective is that telecommunications infrastructure be:

+ Properly installed + Properly tested + Properly documented

C. Cabling system manufacturers may provide training for GSA personnel who will install or modify telecommunications infrastructure. In addition, GSA strongly encourages GSA personnel to obtain training in telecommunications

2 GSA Telecommunications Policies

23 Telecommunications Distribution Design Guide [ Version 8 ] fundamentals from BICSI prior to installing or modifying telecommunications infrastructure. GSA personnel should inquire whether a given manufacturer offers this training.

D. Any penetration created by a telecommunication pathway through fire walls, fire barriers, fire partitions, smoke barriers, and smoke partitions shall meet the requirements in the International Building Code (IBC) and any applicable requirements in the PBS-100, which may exceed the IBC requirements.

E. At the commencement of each project, it is suggested as a good practice that project managers coordinate with the PBS Building Manager responsible for that building. The PBS Building Manager may be aware of other projects that are underway, and might offer helpful logistical insights or identify other building conditions that can affect choices and decisions.

2.2 Initiating New Projects – General

The following information is provided as guidance to any GSA department desiring telecommunications or low voltage additions to facilities, or who will be involved in projects requiring such infrastructure.

2.2.1 New Construction

New construction projects shall include telecommunications infrastructure designed and installed in accordance with the requirements of this document.

2.2.2 Modernization of Existing Structures

GSA facilities undergoing modernization projects shall incorporate telecommunications infrastructure in the project, designed and installed in accordance with the requirements of this document. A GSA IT ITS shall be included in the initial development of the project scope to determine the extent of any required telecommunications infrastructure upgrades.

2.2.3 Minor Remodel (workspace remodel)

GSA facilities undergoing minor remodel projects (typically to make adjustments to accommodate workspace/office arrangements) shall incorporate telecommunications infrastructure in the project, designed and installed in accordance with the requirements of this document. A GSA IT ITS shall be included in the initial development of the project scope to determine the extent of any required telecommunications infrastructure upgrades.

2.2.4 Upgrading Telecommunications Infrastructure to

Support New Technology

GSA will occasionally install new systems (voice, data, video, etc.) at a facility where the existing telecommunications infrastructure may be inadequate for the new application.

24 Telecommunications Distribution Design Guide [ Version 8 ]

GSA IT will verify whether the existing infrastructure is adequate to support the new system(s) and will make recommendations for upgrading the infrastructure where necessary. Any upgrades made to the telecommunications infrastructure shall meet the requirements of the TDDG.

2.2.5 Upgrading Telecommunications Infrastructure to Meet

New Standards

There is not a requirement to upgrade existing telecommunications infrastructure at any GSA facility simply to meet industry standards or the requirements of this document.

However, infrastructure upgrades may be required to correct code violations or to meet system performance requirements.

2.2.6 Infrastructure to Support Other Tenants at GSA

Facilities

Most GSA facilities host tenants that are not GSA operations. The GSA TDDG does not address telecommunications cabling infrastructure to support other tenants. It is possible that other tenants may wish to adopt GSA’s TDDG (this document). Otherwise, the tenants will need to provide guidance regarding the telecommunications infrastructure required to meet their needs.

2.2.7 Damage to Existing Telecommunications

Infrastructure

A. Construction, maintenance, and other activities may result in damage to existing telecommunications infrastructure, including cabling.

B. In the event of damage to telecommunications infrastructure, regardless of the cause or party responsible, GSA personnel shall immediately contact GSA IT, who will determine the repair or replacement strategy for the damaged infrastructure.

C. The GSA IT ITS shall:

• Work with GSA staff to identify any potential methods of temporary/interim repairs.

• Identify the steps necessary to assess whether the damaged infrastructure can be repaired or whether it must be replaced.

D. The party responsible for the damage to the telecommunications infrastructure shall be responsible for the total cost of all temporary/interim repairs and all replacement costs.

All damaged infrastructure shall be restored so as to be within the scope of the original design/installation parameters. This shall include (but not be limited to) all repair or replacement work performed by certified contractors of GSA’s choosing, and all testing and recertification of the infrastructure for full compliance with GSA’s Telecommunications Standards and applicable SCS warranty.

25 Telecommunications Distribution Design Guide [ Version 8 ]

2.3 Initiating New Projects – Specific

All telecommunications infrastructure activity, regardless of the size or scope of the project or quantity of cable involved, must have either prior written approval from, or include prior notification to, the GSA IT ITS to proceed with the design and/or installation. The requirement to contact the GSA IT ITS applies even to small projects, so that the documentation can be updated to reflect the work being done. This includes the following types of projects:

• New construction.

• Renovation of existing structures.

• Upgrading telecommunications infrastructure to support new technology.

• Upgrading telecommunications infrastructure to meet new standards.

• Infrastructure to support other agencies or tenants at GSA facilities.

• All moves, adds, and changes (MACs) at GSA facilities, including MAC work performed by GSA personnel.

• Low voltage cabling to support proprietary systems that will use the telecommunications infrastructure (pathways and spaces) as identified in Building Automation Systems Cabling Standard (ANSI/TIA/EIA-862-A).

It is required that the GSA IT ITS be consulted prior to any planned infrastructure moves, adds, or changes to determine if existing infrastructure may be adequate, or if efforts can be coordinated with other planned or proposed work. Please initiate contact by emailing infrastructure@gsa.gov. The following specific requirements apply:

2.3.1 Telecommunications Room Work

Any GSA department that is planning the installation of cabling or equipment in any Telecommunications Room must coordinate the installation with the GSA IT ITS prior to commencing work, regardless of the type of cabling or equipment to be installed. This coordination is intended to assure efficient use of existing space, and to ensure that resources/spaces planned for future projects are not inadvertently lost due to other uncoordinated equipment.

2.3.1.1 Telecommunications Room Design Parameters

When considering the budgeting requirements for a new project, the following items shall be included for each telecommunications room (TR):

• TRs should be located centrically within the areas they serve.

• Each rack in a TR will support a maximum of 384 cables. Typically, modular furniture offices (cubicles) require an average of 1.25 cables each, and hardwall offices require 4 cables (2 outlets with 2 cables each). TRs shall be sized to hold the required rack space and provide appropriate accessibility.

See TDDG Section 4.5 – Horizontal Distribution Systems for further information.

26 Telecommunications Distribution Design Guide [ Version 8 ]

• TR doors shall swing out of the room.

• For some new construction projects, a TR often requires its own technical power panel inside the telecommunications room. The technical power panel should be fed from a centralized uninterruptible power supply.

• For remodel projects where work on the electrical power distribution system may be limited, it may be sufficient to supply power to the TRs from dedicated circuits out of panels that do not serve loads that are electrically noisy. The electrical engineer shall evaluate the appropriate solution for this situation.

• TRs should be designed such that the environmental conditions are kept within a temperature range of 64 to 81 degrees, in compliance with ANSI/TIA- 569-C. Achieving this requirement commonly requires air conditioning systems, although in some cases an exhaust fan might be adequate. In cooler climates, cooling with outside air is encouraged. Since this is a year-round requirement, it may not be sufficient to rely upon building cooling systems that operate only during the summer. Wherever heat loads are relatively small, it is often sufficient to ventilate the room without providing mechanical refrigeration.

+ RICs require humidity control. Humidity is not typically controlled in a TR.

+ The desirable range is between 45% and 55% relative humidity.

• Environmental monitoring and real-time reporting shall be incorporated in all telecommunications rooms, in accordance with the Environmental Monitoring for IT Spaces (EMITS).

• All telecommunication rooms and technical spaces defined in this document shall be protected by a wet-pipe sprinkler system that is designed and installed in accordance with the requirements in PBS P100-2016 Section 7.8, including the use of sprinkler guards.

• Backbone cabling shall be 50-micron multimode fiber optic cabling and copper backbone cabling.

For more detailed examples of telecommunications room arrangements, please see Appendix 6.2.

2.3.2 Horizontal Cabling

Any GSA department requiring changes or additions to horizontal infrastructure shall contact the GSA IT ITS. No horizontal infrastructure shall be installed in any GSA facility without the GSA IT ITS approval. This includes the installation of any other low voltage infrastructure using the telecommunications pathway/media.

2.3.3 Regional Information Center (RIC)

Regional office buildings shall be designed to include a “Regional Information Center” (RIC) to support local operations and field offices in that region. A RIC is essentially an upsized main telecommunications room (MDF) with support functions that wouldn’t exist in a regular MDF. Power and cooling requirements are more demanding in RICs.

See Section 4.18 – Regional Information Centers and Data Centers for further information.

28 Telecommunications Distribution Design Guide [ Version 8 ]

2.4 Procurement and Installation Policy

A. The primary responsibility for the management and use of information systems, telecommunications, and information technology equipment, software, and services rests with each Department head. Equipment is defined as machines, devices, and transmission facilities used in information processing, such as computers, VOIP telephones, and cables. This section highlights certain procurement policies applicable to the telecommunications infrastructure.

Readers shall consult the FAR for further information.

B. There are two general methods used for the procurement and installation of the telecommunications infrastructure. In larger construction projects, the telecommunications infrastructure installation might either be part of the general construction contract or it could be a separate contract.

C. Use of a GSA IT Blanket Purchase Agreement (BPA) may apply to a given project. Contact GSA IT for further information.

The following policies and procedures apply to the planning and management of telecommunications infrastructure installation as a separate project (apart from other remodeling or new construction work):

2.4.1 Procurement Policy for Information Technology

Infrastructure

2.4.1.1 GSA Information Technology Services Approval

GSA procurement and installation of telecommunications infrastructure must have the prior approval of GSA IT to achieve consistent and competent technical design in compliance with the TDDG and with federal procurement requirements. Requests for approval shall be submitted to the GSA IT Department and will be forwarded to the appropriate internal division for action. Requests for approval must include a description of the procurement and installation procedures and must also identify the following:

• Source of funding.

• RCDD Designer for design services (if appropriate).

• RCDD for construction observation services (optional).

• Structured Cabling System (SCS) cable installer (typically known after bid selection).

The procurement process itself is governed by the FAR.

2.4.1.2 Cabling Infrastructure Materials

Standardization on a cabling infrastructure product line permits GSA personnel to be familiar with the installed infrastructure components at all facilities, and helps them to be prepared to handle moves, adds, and changes to the infrastructure in an efficient manner. Standardization also ensures that there will be performance compatibility with

29 Telecommunications Distribution Design Guide [ Version 8 ] the installed base when additions are made to the infrastructure, and that spare parts and components from one facility can be used at other facilities as needed. Finally, product standardization allows GSA to manage and benefit from consistent warranty coverage at all GSA facilities.

2.4.1.2.1 Structured Cabling System

A. Where additions are made to existing facilities, the design shall specify the use of cabling materials from the same manufacturer whose cabling exists in the building, as long as the existing cabling was produced by an approvable manufacturer.

B. The telecommunications infrastructure design for new facilities shall be based upon the SCS products from an approvable manufacturer.

2.4.1.2.2 Approvable SCS Manufacturers

GSA only accepts cabling materials from manufacturers that are approved through the GSA contracting process. The following criteria are key factors in designating approvable manufacturers and materials:

A. The materials shall be UL Listed.

B. The materials shall comply with Industry Standards.

C. The materials shall be compliant with the Federal Acquisition Regulation (FAR).

D. The company shall manufacture its own products (cabling and connecting hardware). Using cabling from one manufacturer and connectors or patch panels from a different manufacturer is not approvable, unless the manufacturers have established a publicly recognized cooperative alliance and offer a joint warranty.

2.4.1.2.3 Approvable SCS Materials

GSA only accepts cabling materials that meet the following criteria:

A. The materials shall be manufactured by an Approvable Manufacturer (see above).

B. The materials shall be in new, original-manufacturer packaging.

C. The materials shall not be remanufactured, refurbished, recertified, or reused in any way.

D. The…
