NW Construction has been given a possible $255 million contract by the Bureau of Reclamation of the Department of the Interior to assist with a construction project at the B.F. Sisk Dam in California.
The contract will support Phase II of the B.F. Sisk Safety of Dams, or SOD, Modifications project, according to an award notification released Tuesday.
The project includes constructing shear keys, berms, and internal drainage zones; installing toe drains, inspection wells, and weir boxes; installing new instrumentation and safeguarding existing instrumentation; creating a new drainage ditch and backfill; and building a new equipment laydown yard, per a November solicitation.
The vendor will also build and oversee environmental mitigation measures, provide and transport supplies, lay gravel surfacing for new roads, and maintain government field offices and laboratory facilities as part of the Phase II B.F. Sisk Dam SOD Modifications contract.
B.F. Sisk, a 380-foot-tall embankment owned by the Bureau of Reclamation and administered by the California Department of Water Resources, is sometimes referred to as San Luis Dam.
San Luis Reservoir is impounded by the 3-mile dam. It was created between 1963 and 1967 to supply additional agricultural water storage for the California State Water Project as well as industrial and municipal water for the federal Central Valley Project.
