This is a market research notice for potential design-bid-build construction services for erosion control and levee strengthening along the North bank of the Lower American River in Sacramento, California. The Government estimates a target price range of $45 million to $60 million and anticipates construction could be completed within 760 calendar days from a Notice to Proceed, with in-water work limited to July through October. The work is specifically for the North bank sites, separate from a related South bank project. This notice seeks capability statements from interested contractors to inform potential acquisition strategies, and a draft of the plans and specifications is provided for review.
