DOCUMENT INTENT

Please be advised that this document is intended to serve only the purposes of GSA IT. It may not apply to other departments within 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 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 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.

LOW VOLTAGE SYSTEMS

TEAM STRUCTURE

1 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:

o 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.

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

• This document also applies to projects where a formal design is not developed, but where instead the infrastructure is designed and installed by GSA personnel.

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.

D. It is the responsibility of telecommunications distribution designers to coordinate with the other designers on a project (architectural, electrical, mechanical, etc.) to determine that 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

LOW VOLTAGE SYSTEMS

1.1 LOW VOLTAGE SYSTEMS

A. Wherever practical, telecommunications pathway and cabling systems designed for GSA facilities are expected to support and integrate 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.

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.

OUTSIDE PLANT INFRASTRUCTURE

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.

1.3 DOCUMENT INTENT

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), 12th 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

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 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.

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, in due course 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 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.

For further information regarding codes and standards, please refer to Appendix A in the BICSI TDMM as well as the BICSI OSPDRM Bibliography.

K. 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 P100-2013). 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 document has important content, Sections 6.11 through 6.14 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.

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

BUILDING TYPES

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 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.

1.6 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

• Historical Building Remodel

Changes made to buildings that are designated as historical properties.

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

TENANT-SPECIFIC REQUIREMENTS

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

o Historical Building Remodel + Modernization o Historical Building Remodel + Minor Remodel o 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.

1.7 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.

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/or design supporting telecommunications infrastructure:

o Office of the Chief Information Officer (GSA IT) o Federal Acquisition Services (FAS) o Public Building Services (PBS) o Inspector General (IG) o 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 o Responsible for the overall project, as it relates to the structure and serviceability of the building as a whole.

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

KEY TERMS AND ABBREVIATIONS

B. GSA PBS Building Manager:

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

GSA TELECOMMUNICATIONS POLICIES

2 GSA TELECOMMUNICATIONS POLICIES

This section describes internal GSA telecommunications policies, requirements, standard practices and processes associated with designing, installing, and 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 ITS must be incorporated in 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

Internetworking and Security (InterSec) personnel. This includes network design, operations, performance monitoring, optimization, troubleshooting, and disaster recovery. The InterSec staff is also responsible for the planning and development of operational and design standards for local area networks (LANs) and wide area networks (WANs) at all GSA facilities.

o 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 facility, anyone relying upon this documentation for a project shall be responsible to verify that it is sufficiently accurate for their purposes.

o 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 Agency 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.

GSA PERSONNEL

2.1 GSA PERSONNEL

2.1.1 TEAM STRUCTURE

GSA requires the following personnel to work closely as a team with the architects, engineers and designers throughout the entire project lifecycle, starting at the preliminary design phase:

o GSA IT Telecommunications Project Manager (assigned per project) o GSA IT Information Technology Specialist o GSA IT Telecommunications Designer o GSA PBS Project Manager o GSA PBS Building Manager

2.1.2 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.

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 logo stamp and signature. (For more information, see Section 2.7.7 Telecommunications Administration below.) GSA’s objective is that telecommunications infrastructure be:

o Properly installed o Properly tested o 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 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.

INITIATING NEW PROJECTS – GENERAL

NEW CONSTRUCTION

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 is inadequate for the new application.

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).

DAMAGE TO EXISTING TELECOMMUNICATIONS INFRASTRUCTURE

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:

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

2. 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.

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:

o New construction o Renovation of existing structures o Upgrading telecommunications infrastructure to support new technology o Upgrading telecommunications infrastructure to meet new standards o Infrastructure to support other agencies or tenants at GSA facilities o All moves, adds and changes (MACs) at GSA facilities, including MAC work performed by GSA personnel o 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 recommended that the GSA IT ITS be consulted prior to any planned infrastructure moves, adds, or changes to determine if existing infrastructure may be

TELECOMMUNICATIONS ROOM WORK

adequate, or if efforts can be coordinated with other planned or proposed work. 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 should be included for each telecommunications room (TR):

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

o 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.

o TR doors shall swing out of the room.

o For new construction, the TRs should be designed to have their own technical power panel inside the telecommunications room. The technical power panel should be fed from a centralized uninterruptible power supply.

o For remodel projects, the TRs should be fed power from dedicated circuits out of panels that do not serve loads that are electrically noisy.

o TRs should be designed such that the environmental conditions are kept within a temperature range of 68 to 77 degrees and 40 to 55 percent relative humidity. 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.

o 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 GSA PBS P100 Section 7.8, including the use of sprinkler guards.

o 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 to or additional 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. RICs are essentially an upsized main telecommunications room (“MDF”), and support functions that wouldn’t exist in a regular MDF. Power and cooling requirements are more demanding in RICs.

See Section 4.21 – Regional Information Centers and Data Centers for further information.

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

PROCUREMENT POLICY FOR INFORMATION TECHNOLOGY INFRASTRUCTURE

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:

o Source of funding o RCDD Designer for design services (if appropriate) o RCDD for construction observation services (optional) o 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 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 benefit from and manage 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.

TELECOMMUNICATIONS PROJECTS

PROCUREMENT POLICY FOR INFORMATION TECHNOLOGY INFRASTRUCTURE

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 materials shall not be “gray-market,” meaning that they shall be procured via the manufacturer-intended distribution channels.

2.4.1.2.4 Manufacturer 20-Year Warranty

A. The structured cabling system manufacturer must provide a 20-year (minimum) warranty and must require contractor certification under stringent requirements that will ensure a high quality installation. The manufacturer must honor the warranty regardless of the longevity of the installation contractor. In the event that warranted cabling or terminations fail to perform as warranted, the manufacturer must replace underperforming portions of the cabling system at no charge to the Owner for either materials or labor.

B. Where multiple manufacturers have established a publicly recognized cooperative alliance for the purpose of using cabling from one manufacturer and termination materials from another manufacturer, the manufacturers shall demonstrate that their materials cooperatively comply with Industry Standards. The entire system shall be warranted by the manufacturers under a joint warranty (as if the materials were provided by a single entity) subject to the requirements discussed above.

2.4.1.2.5 Installation Contractor 1-Year Warranty

A. In addition to the manufacturer(s) 20-year (minimum) warranty, the installation contractor shall be required to provide a 1-year warranty covering workmanship and craftsmanship, ensuring that the system is installed in compliance with Industry Standards, manufacturer requirements and the requirements of the construction contract.

TELECOMMUNICATIONS PROJECTS

EXTERNALLY DESIGNED

2.5 TELECOMMUNICATIONS PROJECTS

Depending on the size and scope of a project, the GSA IT Telecom Project Manager, working with GSA PBS, will determine whether an engineering firm or contractor is required to develop a telecommunications distribution design.

2.5.1 EXTERNALLY DESIGNED

Externally designed telecommunications infrastructure installation may be handled as stand-alone projects to prepare for the installation of new technology, or as separate projects, running concurrently with another capital project.

2.5.1.1 Design Philosophy

A. An engineered telecommunications design is required for all new construction, modernization or minor remodeling, including technical specifications and drawings to be used as the basis for competitive bidding for the construction contract.

B. GSA requires the use of Registered Communications Distribution Designers

(RCDD) to design the telecommunications distribution infrastructure for all new construction, modernization or minor remodeling, and major telecommunications upgrades at GSA facilities. The RCDD designation is recognized worldwide as a design professional that has met specific professional design experience requirements and has successfully completed an extensive examination…
