The Bureau of Reclamation plans to seek bids for additional work to construct an auxiliary spillway for 198.72-MW Folsom Dam, on California’s American River.
A new solicitation was expected about July 4 for the work, part of a multi-year program of safety modifications at Folsom Dam and Reservoir. BuRec estimates the value of the tasks called for in the upcoming solicitation to be $25 million to $100 million.
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.
Bids for the second phase of the auxiliary spillway project are to include excavation of 1.9 million cubic yards of common and rock materials within 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. (HNN 5/12/08)

BuRec said the solicitation, No. 08SP200172, is to be posted on the Department of Interior’s electronic acquisition system site, http://ideasec.nbc.gov, about July 4. Proposals are expected to be due about 30 days later.
