About this file
This document provides details on a federal contract solicitation for repairs to the Keystone Stilling Basin. The U.S. Army Corps of Engineers Tulsa District seeks to repair damages and fill scour holes at the Keystone Lake Stilling Basin through a construction project. Bidders are not required to handle riprap, coarse aggregate, silt, debris, or other foreign material deposited in the stilling basin except at repair locations. Dewatering of the stilling basins or lowering of the downstream tailwater will not occur during contract performance. All work within the stilling basins must be accomplished under water, and bidders must propose their means and method to do so. Interested parties can find additional details by visiting the opportunity management link provided. The solicitation number for this opportunity is W912BV22R0020.
