Each 4” ducts requiring inner duct shall contain fabric mesh tapes consisting of a minimum of three – 3-inch, 3-cell per tape, maximum of three tapes/nine cells per duct.

c) All newly installed duct runs require a minimum of 36-inches cover from top of duct.

d) If any existing communication ducts are identified within the proposed construction area, a comprehensive site survey shall be required to include Potholing to determine if the duct banks meet the current encasement requirement for bidding purposes. If existing ducts are exposed and do NOT meet the current encasement requirement, then ducts shall be encased to meet the current I3A encasement requirement.

The contractor's RCDD shall provide complete design of the NEC Main Telecommunications Room and Telecommunications Rooms on each floor above, including conduit sleeves, grounding system, fire rated backboards on all walls, air conditioning, etc. and the interior cable distribution system to comply with UFC 3-580-01. Confirm with the User and provide Army convenience telephones on each floor if required. After Construction begins, the Contractor, the RCDD, and the Telecommunications Contractor shall continue to coordinate with the NEC Plans Branch (See JBLM NEC Telecommunications Check Sheet). Telecommunication drawings shall be IAW the UFC 3-580-01 (Chapter 2 and Chapter 4) and the I3A TC (3.0), TIA 606, BICSI TDMM, and the JBLM NEC Plans Branch Telecommunications Drawing Template (T-0, T-1, T-2, T-3, T-4, AND T-5). Also see As-Builts Section.

b) Provide a cable pull-through in the main NEC telecommunications room to a dedicated room with space on the telephone back board for commercial telephone and cable TV service providers. CenturyLink and Xfinity (Comcast) will furnish and install their entrance cables and make connections to their equipment under separate contract with the Government.  Coordinate with these providers and allow them access to perform their work. CATV cables may pass through the NEC telecommunications room only. No terminations in the NEC telecommunications room are allowed. The contractor shall coordinate all requirements for CATV with the commercial provider and shall provide a complete and usable distribution system in each building that complies with service provider standards.

c) The Contractor shall furnish and install interior cables from cable television outlets and from commercial telephone outlets that may be required for the facilities in this project back to the appropriate demarcation point.

d) Comcast and CenturyLink will make the connections to their equipment under separate contract with the Government.

e) Do not use J-hooks. Provide cable runways in telecommunications rooms and wire basket cable tray for horizontal distribution with minimum 1” conduit from tray to each cable TV, voice and data outlet.

f) Coaxial cable and Category 6 cable shall not be installed in the same conduit.

2.2. Provide a standard I3A/TIA information outlet on the telephone backboard for connection to the Base EMCS and coordinate the outlet location with JBLM PW.

2.3 Coordinate the following with NEC:

Provide TIA/EIA fire-rated A/C (interior-grade) backboards (unpainted) on all walls in the telecommunication rooms per TIA/EIA 569.

b) Confirm standard administrative outlet configuration and labeling requirements (three CAT 6 cables to provide two data and one voice). JBLM DPW/NEC requires Contractor to follow the NEC JBLM and TIA 606 Labeling Scheme and the JBLM NEC labeling scheme for labeling telecommunications cables/terminations.

c) Cable Tray Installation -- Wire basket cable trays – ensure 12-inches of clearance above the cable tray and ensure at least one side (@ 10-inches) of the cable tray has clearance (i.e., extend the horizontal supports of the cable tray and located associated vertical supports in a manner that provide a minimum of 10 inches of clearance along cable trays) for adds, moves, and changes.

2.4 Cable test reports.  Include the model/serial number of the test equipment, calibration certificate, and name of technician. Hand generated reports are not acceptable. The JBLM DPW/NEC will require insertion loss tests for all telecommunications cable.

2.5 Provide CAT 6 cables that are UL-listed for wet environments where cables are routed in conduits installed inside or below slab-on-grade concrete floors.

2.6 Where protective distribution systems are required, provide systems by Holocom, Inc., or approved equal. Cable colors shall be blue for data, white for voice, red for SIPRNET, and yellow for JWICS.

2.7 Seismic Bracing: Brace or anchor equipment to resist horizontal forces acting in any direction per the site class and seismic use group as defined in the IBC and the I3A TC.

2.8 Field Radio Antenna:  Coordinate with contracting officer to determine if a field radio antenna is required by the building occupant.  If required, provide a 2-inch raceway from the Duty Office (or location designated by the User) to the exterior of the building with a grounding bushing at the interior and a weather head at the exterior and coax cable for a field radio antenna connection.  Coordinate installation requirements with the User.

2.9 Elevator Control System: Data outlets for Elevator Control System network connections shall be installed outside the elevator equipment enclosure.  The data outlet shall consist of a fully terminated connection in a customer face plate.  The customer faceplate shall be protected from tampering through the installation of a cover/enclosure.  The cover/enclosure shall be labeled the same as the customer face plate. Coordinate with the JBLM NEC Plans Branch for design/configuration and the NEC JBLM TIA-606 Labeling Scheme.
