Angostura Dam Spillway Repair

This pre-solicitation notice seeks capability statements from small businesses for a spillway concrete repair project at Angostura Dam in South Dakota. The Department of the Interior Bureau of Reclamation will remove and replace approximately 4,500 square feet of damaged concrete on the downstream face of the spillway to a depth of six inches. Construction must occur between August 15 and November 30 to avoid flood releases, and care must be taken to not dewater the stilling basin or allow material to fall into it. Capability statements are due by November 14, 2023 and will be evaluated based on experience with similar specialized projects subject to the identified constraints.

The opportunity is set aside for 8(a), small, small disadvantaged, woman-owned small, and service-disabled veteran-owned small businesses. The project value is estimated between $5 million and $10 million. Respondents must demonstrate experience with spillway concrete repair projects requiring removal and replacement of large concrete areas to a specified depth while adhering to a limited in-water work window and restrictions around dewatering adjacent structures. Capability statements should be submitted to Contract Specialist Mitchell Frost by the specified deadline.
