7. SOW summary ASP to install 2” conduit (hand trenched) with mule tape from the “Meet Me Point” to the proposed Ciena location. Total run of the new conduit is 18’ and will be installed at the depth of 3’. Photos showing the trench depth are required. ASP to install 380’ of mule tape in existing conduit from 13 Mile Road to the site for AT&T to pull fiber to site. AT&T to mount proposed NID (Ciena 3911) to new PPC H-frame east of existing Sprint platform. ASP to install (2) 2” conduits (hand trenched) from proposed Ciena location to existing steel equipment platform each for power and telco. ASP to install (2) new 1¼” flexible conduits attached to perimeter beam of existing steel platform for power and telco connection to the proposed NID. – Power conduit will be installed between battery cabinet and the proposed Ciena with a junction box and whip capable of connecting temporarily to the existing +24VDC Power Plant during the interim phase and then connecting to the proposed -48VDC Power Plant upon completion of the equipment upgrade. Approximate length of the power conduit is 17ft. – Telco conduit will run from proposed MMBS to proposed Ciena. Approximate length of telco conduit is 10 ft. ASP to run 17 ft of 12 AWG power cables from the power plant to the proposed location of the Ciena (installed by AT&T). ASP to run #6 ground wire from the proposed MMBS and proposed power plant to the existing equipment platform and from the proposed Ciena to the new H-frame to tie new equipment into the site grounding system. Approximate ground wire length is 12 ft. ASP to restore all work areas to the pre-construction condition.
