Y -- SRS SPILLWAY FLOOD DAMAGE REPAIR SOL DACW57-97-B-0015 DUE 051597 POC Contract Specialist MARTINA HARWOOD (503) 326-5816 (Site Code DACW57) Significant erosion in the SRS spillway was caused by water flows over the spillway during the winter and spring of 1996. The SRS is located in Cowlitz County, approximately 30 miles east of Castle Rock, Washington near river mile 13 on the North Fork of the Toutle River. Contractor is required to restore portions of the spillway to pre-erosion condition. The work includes care and diversion of water to provide a dry work area; excavation of rock, roller compacted concrete (RCC), and their disposal; and placement of 5000 cubic yards of roller compacted concrete. Excavation will be mostly in an area of the spillway where an existing creek was partially filled with rock fill and capped with RCC during original construction. Required excavation will breach the RCC cap/rock fill and form entrance and exit channels to and from the breached area. Upon award, work must be completed within 60 days, before additional water flows over the spillway and increases the amount of erosion and potentially jeopardizes the spillway design function. Technical questions should be addressed to Chris Budai at (503) 326-5146. IFB will be available on or about April 15, 1997 at a charge of $30.00 per set. Tentative bid opening date is May 15, 1997. Estimated cost range is between $500,000 and $1,000,000 and should be bid per line item. This procurement is open to both large and small businesses. The size standard for small business concerns, including its affiliates, having an average annual gross sales or receipts for the preceding three years not to exceed $17.0 million.
