2 June 2008

This standard supersedes Langley AFB Premise Wiring Distribution Systems Standard dated prior to 2 June 2008. This standard also supersedes Contract Specifications Section 16710 and Section 27 10 00 dated prior to 2 June 2008.

FOREWORD The Langley Air Force Base (LAFB) Telecommunications Building Cabling System (TBCS) Standard applies to the Military Construction Projects, Civil Engineering Renovation Building Projects, in accordance with Engineering Technical Letter (ETL) 02-12, Unified Facilities Criteria (UFC) 3-580-01, and technical references provided in this standard. The LAFB TBCS Standard will be used for Military Construction and renovation projects and work for other customers where appropriate. Recommended changes with supporting rationale should be sent to 1 CS/SCX for consideration.

The intent of this standard is to:

(1). Ensure the system is complete and ready for customer occupancy.

(2). Prevent facility defacement that would occur if communications infrastructure were not integrated into the facility design and acquisition process.

(3). Comply with technical architectures and basic standards to ensure compatibility, flexibility, and long-term customer support.

(4). Provide standardization thereby reducing the need and cost of future modifications that would result from changes in facility occupancy or user reorganization.

(5). Eliminate funding disconnects that result from fragmenting appropriations sources for communications infrastructure acquisition.

(6). Realize beneficial effects of enhanced maintenance effort and training qualification by providing standardized communications throughout Langley AFB.
