USACE SPK DBB Construction - LAR C3B North - Sacramento, CA

The United States Army Corps of Engineers (USACE) Sacramento District (SPK) anticipates a potential requirement for design-bid-build (DBB) construction services to conduct erosion control and levee strengthening protections along the North bank of the Lower American River (LAR) in Sacramento, California (CA). The anticipated project is required to continue American River Common Features (ARCF) erosion reduction efforts along the LAR. Prior efforts were awarded under USACE contract W9123824C0014, LAR Contract 3 (C3) A. The anticipated forthcoming requirement is referred to as “LAR C3B” (Contract 3B). The Government anticipates work will be required along the Sites 3-1 and 4-2, spanning approximately 1.8 miles along the North (right) bank of the Lower American River from Howe Avenue upstream to near Harrington Way. The Government anticipates work under fully designed Government specifications that entails excavation, material placement, and embankment regrading; installation of soil-filled rock slope protection along the waterside levee face; construction of buried launchable rock toes and launchable overbank trenches; development of planting benches integrated with instream woody material; import and placement of riprap; structural tie-ins with existing rock revetment features; and complete temporary site stabilization across disturbed soil areas. The Government estimates the anticipated requirement can be constructed within four-hundred and eighty (480) calendar days from Contractor receipt of Notice to Proceed. The Government estimates work may be completed in late Spring through Fall 2027 and in 2028. The project is anticipated to require working in the active channel of the American River; in-water work is anticipated to be limited to performance from July through October. If market conditions indicate this estimate or timeline may be unrealistic, Respondents are encouraged to provide specific information (such as known equipment lead times or other timeline conc
