SEPA MDNS South Terminal Moderniz tion,Phase 2 Pag 3 of_.5,) The new duct bank between Building T-6 and the crane substation is approximately 500 feet in length, with a 48- inch minimum depth and a 36-inch minimum width. The distance between the crane substation and the vault adjacent to the wharf is approximately 400 feet in length and 48 inches minimum width/depth. Construction of all the new duct banks will include approximately 550 cubic yards of excavation,250 cubic yards of new buried concrete duct bank, 200 cubic yards of back fill,60 cubic yards of gravel ballast,and 5,000 square feet of asphalt concrete pavement. The quantities for the portion within the 200-foot shoreline area are as follows and are included in the previous numbers given: Construction of the new duct banks within the 200-foot shoreline area comprises 400 cubic yards of excavation, 200 cubic yards of new buried concrete duct bank, 150 cubic yards of backfill, 50 cubic yards of gravel ballast, and 3,700 square feet of asphalt pavement. The total disturbed area within the 200-foot shoreline area is 3,700 square feet. There will be 7 new equipment pads of various sizes for the electrical equipment, all within the 200-foot shoreline area. The total excavation volume is approximately 70 cubic yards. The total concrete volume is approximately 50 cubic yards. The total crushed rock volume is approximately 20 cubic yards. The total area of disturbance is 1,500 square feet. Also within the 200-foot Shoreline area,there will be two buried concrete vaults (located landward of the wharf s bulkhead) with a volume of 350 cubic feet each,for a total of 700 cubic feet. The total volume of excavation for these vaults will be approximately 100 cubic yards and the area of disturbance will be approximately 350 square feet. Utilities will be installed using traditional land based construction equipment. Conduits from transformer and switchgear to the wharf will run in buried duct banks. Conduit on the wharf will be buried in the gravel ballast under the asphalt concrete pavement.If needed,improvements may be made to the existing stormwater system. No new impervious surfaces would be added, and any improvements would connect to the existing stormwater system. Work is expected to begin in August 2017 and will adhere to the work window that allows in-water construction work (typically July 15th—February 15th).The project is expected to end in June 2019.
