99 -- COAST GUARD SITE SURVEY SOL 9T8G401A DUE 103098 POC Chris Matthews (501)637-3892 E-MAIL: chris.matthews@gsa.gov, chris.matthews@gsa.gov. The General Services Administration intends to issue an order for a site survey of 18 microwave sites throughout the bay in support of the U.S. Coast Guard, Maintenance & Logistics Command Pacific, Telecommunications Branch, Network Management Section (te-4), Coast Guard Island, Alameda, CA. MLC -- Pacific's mission is to provide Telecommunications Project support including engineering, design, implementation, and integration of telecommunications products and services. This project will replace the existing Bay Area Communications System (BACS) analog microwave (2Ghz) with a new Joint Optical Network (JONET) digital (8Ghz) microwave system. The BACS microwave system supports a variety of Coast Guard missions including Search and Rescue (SAR), Law Enforcement, Aids to Navigation, Coast Guard Data Network, Vessel Traffic Service, Marine Safety, Pollution Control and Response, Protection of our waterway and enforcement of local, state, and federal laws and treaties. The Coast Guard must move out of the (2Ghz) frequency spectrum by January 1999. The new digital Microwave Communications System (JONET) shall take advantage of state of the art technology to reduce maintenance efforts, operational cost, and fit within the FCC mask for spectrum efficiency. 1.2 BACKGROUND AND OBJECTIVE: The Contractor shall perform, site surveys, tower inspections, tower analysis, foundation assessment, soils investigations, and path analysis at the sites listed below in paragraph 1.2.1. The Contractor shall provide a written report of findings along with recommendations for hot cut over to the new digital (8Ghz) microwave System. The Contractor shall provide all transportation, test equipment, personnel, consumables, and equipment required under this Statement of Work. The Coast Guard expects to reuse most of the existing towers, foundations, buildings, and shelters for the migration from (2Ghz) analog microwave to (8Ghz) digital microwave. The Contractor shall determine if it's economically feasible to reuse the existing towers, foundations, buildings, and shelters for the transition to the new digital microwave system. The Contractor shall determine if the existing shelters, building, towers, and foundations can support the new digital microwave and the existing analog microwave system during the transition from analog to digital in support of a hot cut over. The Contractor shall provide a project plan and schedule in Microsoft Project or equivalent project management software describing how he plans to complete the work required in this Statement of Work. The project plan shall include three copies of a PERT Chart (using critical path method) and Gantt Chart (depicting task breakdown structure) that shall be provided for Coast Guard review and approval prior to the start of the work outlined in this statement of work. The Contractor shall provide periodic progress reports to the Coast Guard on a monthly basis until all project milestones and tasks have been completed and approved by the Coast Guard. The Contractor shall provide a list of client references with phone numbers that the Coast Guard can contact to verify that the Contractor has done similar work of this nature. The Contractor shall ensure the digital microwave radio product model used for the path analysis has a high power feature. The digital microwave radio high power feature shall be for both the Narrow Band spurs and Wide Band ring microwave links where applicable for long microwave path. The Contractor shall use the high power feature to reduce the size of the antennas and achieve the desired system reliability of (99.999). The digital microwave radio product for the Narrow Band spurs shall fit within the FCC Mask for spectrum efficiency of 7.5Mhz (16 DS1s). The digital microwave radio product model for the Wide Band ring shall fit within the FCC Mask for spectrum efficiency of 30Mhz (3 DS3s). The Contractor shall use a digital camera to photograph towers, foundation, building, equipment, shelters, cables, and support equipment. The Contractor shall provide three hard copies of all photographs and one copy on a floppy disk that can be viewed by the Coast Guard on a PC using Microsoft Office 97. The existing analog (2Ghz) microwave system here in after referred to as BACS is depicted in Appendix A. The new digital (8Ghz) microwave system here in after referred to as JONET is depicted in Appendix B. The new digital microwave system JONET shall consist of 4 Major Nodes in a Synchronous Optical Network (SONET) Radio Ring Architecture. The microwave link between Group San Francisco and Vessel Traffic Center shall be comprised of a SONET Radio and Terrestrial Fiber Optic Ring. The new digital microwave system JONET shall consist of 5 new digital microwave Wide Band SONET radio sites located at Vessel Traffic Service, Group San Francisco, Coast Guard Island, Mount Tamalpais, and Mount Diablo. The new digital microwave system JONET shall consist of 13 Narrow Band Asynchronous microwave sites located at CAMSPAC Transmitter Site, CAMSPAC Receiver Site, Point Reyes Lighthouse,Station Bodega Bay, Mount Jenner, Point Bonita, Mare Island (Busch Bluff), Station Rio Vista, Marine Safety Detachment Concord, Bay Point, Mount Umunhum, Air Station San Francisco, and Station Monterey. The new digital microwave network system shall be comprised on 18 microwave sites shown in paragraph 1.2.1 below throughout the Greater San Francisco Bay Area. EXISTING BACS (2GHZ) MICROWAVE SITES: The existing BACS microwave radio system is composed of 18 microwave sites located throughout the Greater San Francisco Bay Area.
