UPDATE – U.S. seeks bids for spillway work at 198.72-MW Folsom

The Bureau of Reclamation seeks bids for additional work to construct an auxiliary spillway for 198.72-MW Folsom Dam, on California’s American River. Bids are due Aug. 4.

In a solicitation issued July 5, BuRec estimates the work to be worth more than $10 million. A pre-solicitation notice estimated the value of tasks to be performed under contract to be $25 million to $100 million. (HNN 7/3/08)

Work described in the solicitation, Folsom Dam Phase II Safety of Dams Modifications, is part of a multi-year program of safety modifications at the dam and reservoir.

Construction began in January as a Joint Federal Project by BuRec, the Corps of Engineers, California Department of Water Resources, and Sacramento Area Flood Control Agency.

The second phase of the auxiliary spillway project includes excavation of 1.9 million cubic yards of common and rock materials in the auxiliary spillway chute and stilling basin. The contractor also is to haul materials, build a cofferdam, and relocate a water supply pipeline serving the city of Folsom.

The auxiliary spillway is being built to address the hydrologic risk to Folsom Dam identified through BuRec’s Safety of Dams program. The structure also is expected to achieve the Corps’ objective to double the flood protection for the city of Sacramento, to cope with a 200-year flood.

In May, BuRec awarded a $3.2 million construction contract to DD-M Crane and Rigging, Alameda, Calif., to perform dam safety modifications to Dike 5, an earthen embankment, as part of the larger dam safety program.

The solicitation, No. 08SP200172, may be obtained from the Department of Interior’s electronic acquisition system site, http://ideasec.nbc.gov. Proposals are due Aug. 4 to the Bureau of Reclamation, Attention: Don Neal, MP-3824, 2800 Cottage Way, Room E-1815, Sacramento, CA 95825-1898.
