The Bureau of Reclamation’s Mid-Pacific Region is conducting a market survey seeking interested companies for the second phase of an auxiliary spillway being built at 198.72-MW Folsom Dam on California’s American River. Responses are due Feb. 21.
The intended procurement, estimated at more than $10 million, includes excavation of 1.9 million cubic yards of rock and other material from an area within the auxiliary spillway chute and stilling basin. Work also would include construction of access roads and a cofferdam, and relocation of a water supply pipeline serving the city of Folsom.
The auxiliary spillway is being built as a Joint Federal Project by BuRec, the Corps of Engineers, the California Department of Water Resources, and the Sacramento Area Flood Control Agency. It will include an approach channel, control structure with submerged tainter gates, a concrete-lined spillway chute, and a stilling basin to dissipate energy before water is discharged into the American River.
The spillway is to address the hydrologic risk to Folsom Dam identified through BuRec’s Safety of Dams program. It also is to achieve the Corps’ objective to double flood protection for the city of Sacramento, to withstand a 200-year flood.
Kiewit Pacific Co. of Concord, Calif., construction contractor for Phase I, is responsible for initial spillway excavation, construction of a roadway, and modifications to two wing dams. Federal, state, and local officials marked the start of construction in January. (HNN 1/21/08)
