Folsom Main, Left Wing and Right Wing Dams

The U.S. Army Corps of Engineers Engineering District Sacramento is seeking to raise the elevations of the Folsom Main Dam, Left Wing Dam, and Right Wing Dam through solicitation W91238-22-R-0055. The construction project aims to increase flood protection for communities along the American River in California. Interested parties will need to submit technical and pricing proposals by a date to be specified in the formal solicitation, and the agency will evaluate submissions based on unspecified criteria. The draft solicitation does not provide response deadlines or other scheduling details.

There is no set-aside designated for this pre-solicitation, and estimated values range from $100-250 million to be completed over three years. The work includes raising portions of the three dams and installing reinforced concrete floodwalls, with specifications referencing required construction sequencing, environmental protocols, and coordination with the U.S. Bureau of Reclamation. Technical drawings depict design details for the dam elevations and modifications to Tainter gates and anchorage at the main dam.
