- Description
- THIS NOTICE IS PROVIDED FOR INFORMATION PURPOSES ONLY. THIS OPPORTUNITY IS AVAILABLE ONLY TO CONTRACTORS UNDER W912DQ08D0036. RECOVERY Task Order Information: Bonneville Stilling Basin Erosion Repair: Repair of erosion and undercutting in the north apron of bays 2-3. A series of large erosion holes exists on the downstream edge of the concrete apron on the north end of the spillway. In 2008, divers measured the undercutting with a 25 probe; however the probe was not long enough in some areas to measure the undercutting. The extent of the undercutting is unknown but estimates show as much as 25% of the basin rock that supports the apron is gone. A soft green clay layer transverses this area. Repair of erosion holes in bays 9, 12 & 14. There is approximately 4 to 5 feet of concrete missing from the ogee floor at Bay 9. Bays 12 and 14 showed similar amounts of removed concrete. Bay 14 appears to have more concrete removed (as much as 6 feet) at higher elevations on the ogee. There is about 5 feet of concrete missing in Bay 9 directly above the downstream drainage gallery of the spillway. The as-built drawings indicate 10 to 12 feet of unreinforced concrete coverage above the drainage gallery. John Day Downstream Lock Gate Replacement: The John Day Lock downstream lift gate is a single leaf gate that has no redundancy. The John Day Lift Gate is a welded steel structure with 24 arch frames and a top plate girder spanning horizontally between the concrete lock towers. The upstream side of the gate has an integral 1-1/8 inch thick steel plate which contains the upstream pool. John Day Flow Deflectors: The work to be performed under this project consists of providing the labor, equipment, and materials to construct a flow deflector in the tailrace of the John Day Project as shown on the contract documents. To perform this work, the area will need to be dewatered to a depth of about 55 feet using existing stoplogs and fabricated guides. This includes removal and reinstallation of Avian Deterrent Array cables that will be required for tailrace access to the new deflector location. The work also includes relocation of Top Spillway Weirs (TSW) at the spillway at the John Day Project. Relocation of the TSW's and the spillway stoplogs must be performed by a barge crane. The work consists of fabrication, concrete demolition, anchor installation, mass concrete placement, work over water, dewatering, avian array removal and reinstallation, barge crane work, diving, and other miscellaneous tasks to complete the work as defined in the contract documents.
