Y -- ASTORIA EAST BOAT BASIN BREAKWATER REPAIR SOL DACW57-98-B-0016 DUE 102298 POC Contract Specialist MARTINA HARWOOD (503) 808-4614 (Site Code DACW57) The U.S. Army Corps of Engineers, Portland District (CENWP) is purchasing steel sheetpile to install in the East Astoria Boat Basin, Astoria, Oregon, for a partial repair of the north breakwater, approximately 400 feet of a 2350 foot wall. This contract will be for the construction/installation of the sheetpile. 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 sheetpile structure which fronts the river as the north breakwater. This construction project entails repair of the breakwater, which consists of dredging 12,000 yd3 to 15,000 yd3 at the base of the existing structure to remove the existing toe rock and overlying sediment. The dredged toe rock will be placed temporarily on a barge or to one side of the structure. New sheetpiles will be driven approximately 5 feet outside of the structure, completely surrounding the entire 400 feet of breakwater. Sand/gravel fill will be placed between the new and old sheetpiles, 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 offsite. The tops of the existing sheetpiles will be cut off to allow for the eventual placement of a new road surface between the new sheetpiles. The new sheetpile will be terminated at elevation 17.5'. The sheetpile is expected to consist of the market equivalent of PZ 40 sheets. This procurement is open to both large and small businesses, the size standard for which is a concern with annual gross receipts not in excess of$17 million dollars. The estimated cost range for this construction project is between $1 to $5 million. The Invitation for Bid may be available on CD ROM on or about 22 September 1998. Tentative Bid Opening will be 22 October 1998. For technical questions please contact Jeff Sedey at 503-808-4937.
