Statement of Work

1. Section 1.5, Key Elements. Add element T as follows: Install communications distribution to include copper telephone for telephone service and Single Mode Fiber (SMF) cables for Data Network services.

2. Section 2.2, Standards. Add item I. as follows: Technical Criteria for the Installation Information Infrastructure, February 2010.

3. Section 3.5.1.1.1, Telephone and LAN. Rewrite as follows: “A 25 pair copper telephone cable and a 12 strand SMF cable will be installed a lockable cabinet within the Radome along with any equipment necessary to provide at least 8 data and 3 telephone positions. Distribution for additional external positions will be provided if required.

4. Section 3.5.12, Cable Channel troughs, item C, I, Rewrite as follows: Two (2) within the channel trough 2 IN conduit shall be employed to provide fiber optic and telephone connectivity. All five (5) STT testing positions shall have fiber optic connectivity with each other and have connectivity to the nearest communications manhole in the area.

The 2 each, 2 IN conduit shall connect to a handhole at the outer circumference of the RADOME drive ring at a QUAZITE underground enclosure (or equivalent underground enclosure meeting or exceeding ANSI/SCTE 77-2007 & Revisions) 37 IN x 26 IN x 24 IN underground enclosure and then continue to the nearest manhole. The Contractor is responsible for determining the number and placement of manholes to accommodate the communications conduit connectivity. The electrical and communications underground conduits shall be placed in the same ductbank were possible. Contractor shall confer with Government COR/COTR for specific guidance on ductbank conduit size and type.

Separate manholes shall be used to separate the electrical and communications conduit runs. All designs and installations of underground ductbanks and manhole access points shall comply with TYAD electrical and communications standards and codes.

5. Section 3.5.12, Cable Channel Troughs, item G, sub item a. Rewrite as follows: The Contractor shall install a series of communication manholes(s) between the existing communications manhole 45 and the proposed Equipment Shelter Site. The COR/COTR will provide the Contractor with information on the physical location of the manhole at a later time.

6. Section 3.5.14, Communications Duct Banks, items A and B. Delete A and rewrite B as follows: The Contractor shall install communications ducts providing pathway(s) for the routing of fiber cable and copper wire communications lines to the Equipment Shelter Site. The Contractor shall extend the existing communications duct-bank to the Equipment Shelter Site from existing communications manhole 45 connecting outside circumference of the existing RADOME drive ring. Electric and communications duct-bank routing pathway shall be shared and concrete encased were possible. Government

COR/COTR approval is required prior excavation and installation of electrical and communication duct-banks. The following apply:

A. Delete A.

B. The Contractor shall install two (2) PVC, 4 IN, SH 40 conduits from 45 and have termination at the last newly installed communication manhole outside the Equipment Shelter Site drive ring at the same depth. The Contractor is required to rod and mandrel a duct bank path to manhole 43, where the copper is located (CA-2, 1026- 1050) and into building 72 (SATCOM) and into the communications closet on the 1st floor, where the fiber optic cable (12 strand SMF) will run from to ensure a good path is available for this projects cables. The COR/COTR shall provide the Contractor with duct bank run and communications manhole sizing and installation requirements and practices as per TYAD Electrical Design and Construction Standards.
