Description

DESC: The U.S. Army Corps of Engineers, Portland District (CENWP) intends to award a contract for repair of the remainder of the north breakwater, at approximately 1400 lineal feet of 2350 foot breakwater, in the East Astoria Boat Basin, Astoria, Oregon. The mandatory work in the contract is for approximately 200 lineal feet of breakwater, demolition and replacement of 75 feet of causeway, and relocation of floating docks. Options are included in the contract to complete the repair of the entire breakwater. Including options, the contract will likely span over three work seasons, 2001/2002, 2002/2003, and 2003/2004. The Astoria East Boat Basin is located along the southern shore of the Columbia River between river mile 15 and 16 and the East Boat Basin lies between 33rd and 39th streets in Astoria. The East Boat Basin contains a water area of about 45 acres. The existing structures protecting the basin include two rubble mound breakwaters at the west entrance (west breakwaters), one rubble mound breakwater at the east entrance(east breakwater) and a sand-filled, double-walled sheet pile structure which fronts the river as the north breakwater. This construction project entails repair of the breakwater, which consists of dredging approximately 5922 cubic yards at the base of the existing structure to remove the existing toe rock and overlying sediment. Options are included in the contract for dredging at the base of the existing structure to remove an additional 56409 cubic yards of existing toe rock and overlying sediment. New government-furnished sheet piles will be driven approximately 5 feet outside of the structure, completely surrounding the entire 200 lineal feet of breakwater. Sand/gravel fill will be placed between the new and old sheet piles, new tie-rods spaced at 7 foot centers and walers will be installed at elevation 4.0' MLLW or above, and new toe rock will be replaced at the toe. The dredged toe rock will then be replaced up against the new toe rock. The dredged sediments will be disposed of in the flow lane. The tops of the existing sheet piles will be cut off to allow for the eventual placement of a new road surface between the new sheet piles. The new sheet pile will be terminated at elevation 17.5 feet. This procurement is set aside for small businesses only, the size standard for which is a small business concern with annual gross receipts not in excess of $27.5 Million. The estimated magnitude of construction for this project is between $5,000,000.00 and $10,000,000.00.
