The Bradbury Dam Outlet Valve Replacement project, solicitation 140R2026R0018, is a total small business set-aside managed by the Bureau of Reclamation under the Department of the Interior. The primary objective is to replace existing 30-inch valves with fixed-cone valves to improve the operation and efficiency of water releases within the outlet works. Located in Santa Barbara County, California, the project has an estimated cost between 1 million and 5 million dollars. The scope of work includes mobilization, the implementation of a temporary bypass pump system, general electrical system work, and the removal and installation of valves. Performance must begin within 7 calendar days of the award and be completed within 365 calendar days, with a critical mandate that the facility must be able to control and release water through the new valves by December 15, 2027.
Award will be granted to the responsible offeror submitting the lowest evaluated price, provided they meet acceptability standards for non-cost factors, including a coordinated construction schedule and relevant experience. Technical proposals are evaluated on an acceptable or unacceptable basis without ranking or trade-offs. The contract is subject to the Davis-Bacon Act and requires performance and payment bonds. Quality standards are governed by various reference standards, including USBR Reclamation Safety and Health Standards, ASME, ASTM, and NFPA 70. Final inspection and acceptance of materials will occur exclusively at the jobsite following installation and testing. Proposals must be submitted in three separate volumes covering business representations, technical capabilities and past performance, and pricing.

The contract for the Stampede Penstock and Butterfly Valve Rehab involves the rehabilitation of critical water infrastructure under the Bureau of Reclamation’s Mid-Pacific Region, with performance occurring at a project site under its jurisdiction. The scope encompasses multiple construction divisions including earthwork, marine construction, electrical systems, finishes, and hazardous material abatement, with specific requirements for abrasive blast cleaning and coating application on carbon steel, ductile iron, and steel components, as well as demolition, repair, and replacement of damaged infrastructure. Work must begin within seven days of notice to proceed and be fully completed within 600 calendar days, including final site cleanup. All materials must be sourced from the original manufacturer’s production lot, preserved against environmental degradation, and packaged according to strict standards requiring complete product identification, heat-shrink labeling with specified font and length, and non-conductive, heat-resistant cable tags. No bar-coding or military packaging standards are mandated, but industry standards such as ASME BPVC-V-21, ASME BPVC-IX-21, ASTM A802-19, and SSPC-SP standards govern inspection, testing, surface preparation, and welding qualifications. Acceptance of all materials occurs only at the jobsite after installation and testing, with the contractor fully responsible for damage or loss post-inspection.
The solicitation is structured under a Lowest Price Technically Acceptable (LPTA) evaluation methodology, with no weighting assigned to factors, and award contingent upon proposals being deemed acceptable across all criteria—Technical Capability (including construction schedule and experience) and Past Performance—with price serving as the sole differentiator among technically acceptable offers. Proposals must be submitted electronically in three distinct volumes—Business, Technical, and Pricing—each with specific formatting requirements including a table of contents, cross-references, and cover page, and must be emailed to the contracting officer, Charlesetta Seibure, by the June 9, 2026 deadline. All offerors must provide a Unique Entity Identifier and CAGE code if using covered telecommunications equipment, and must represent their small business status under NAICS 237110, with a $45 million size standard.
