The Corps of Engineers’ Nashville District seeks bids to construct a concrete seepage barrier at 270-MW Wolf Creek Dam, near Jamestown, Ky. Proposals are due March 11, 2008.
The Corps estimates the cutoff wall will cost from $100 million to $250 million. (HNN 11/12/07) The contractor is to begin work within 15 days of notice to proceed, and will have four years to complete the work.
The Corps previously identified Wolf Creek as one of several dams critically near failure or having extremely high life or economic risk. (HNN 12/5/07) An independent review panel subsequently agreed the 5,736-foot-long, 258-foot-tall, earthfill and concrete gravity dam has a significant potential for failure.
The contractor is to complete a partially constructed, 4,500-foot-long grout curtain and install a 4,200-foot-long, two-foot-thick concrete seepage barrier with a total surface area of about 980,000 square feet. The cutoff wall is to be built between two grout curtains as part of the government’s $309 million seepage repair plan.
