DRAFT Plans - LAR C3B South - May 2025.pdf

This is a draft plans document for the LAR C3B South construction project being procured by the United States Army Corps of Engineers (USACE) Sacramento District. The project involves erosion control and levee strengthening protections along approximately 1.5 miles of the South bank of the Lower American River in Sacramento, California, specifically along Site 4-1 extending from Watt Avenue upstream to near Mayhew Drain. The work is a continuation of the American River Common Features (ARCF) erosion reduction efforts and represents a separate acquisition from the concurrent LAR C3B North project. Construction activities include installation of launchable rock toe, launchable trench, and bank protection systems; tie backs along the riverbank; and excavation, placement, and regrading of material on the riverbank slope and levee embankment.

This project will be procured using a design-bid-build (DBB) acquisition strategy and is being market-researched through a Sources Sought Notice (W9123826S0015) to assess availability and capability of small business firms prior to formal solicitation. The effort builds upon prior work completed under USACE contract W9123824C0014 (LAR Contract 3A). While this particular document appears to be technical plans supporting the procurement, the actual solicitation has not yet been released, and no award date or pricing information is available at this sources sought stage. The contracting officer should reference the formal solicitation when it is issued for complete requirements, specifications, and submission deadlines.
