This is a special notice prepared in accordance with Defense Federal Acquisition Regulation Supplement (DFARS) PGI 206.302-1(d) “Only one responsible source and no other supplies or services will satisfy agency requirements.” The U.S. Army Corps of Engineers, Walla Walla District, is executing a firm-fixed-price contract for the Little Goose Turbine Discharge Ring Upgrade and Blade Cavitation Repair. A cr...
View moreThe statutory authority for this brand-name restriction, to be made as a part of the larger construction effort, is 10 U.S.C. 3204(a)(1) as implemented by RFO FAR 6.103-1(b) Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements, application for brand name descriptions.
The Government intends to solicit the Construction action in November 2026. The NAICS code is 237990 Other Heavy and Civil Engineering Construction. The associated Small Business Size Standard as defined by the U.S. Small Business Administration is $45 million.
THIS NOTICE IS NOT A REQUEST FOR COMPETITIVE PROPOSALS OR BIDS. This is a notice of intent to procure brand-name materials within a larger construction contract. The Government is seeking information from responsible sources who can provide alternative blade seals that meet the rigorous dimensional tolerances, material compositions, and exact fit requirements strictly necessary to prevent oil leakage.
Interested parties must provide a statement of capability with clear and convincing evidence (including independent laboratory testing and historical performance data on USACE Kaplan turbines) demonstrating that their proposed alternative seals can match the precise strength, rigidity, and exact shape dimensions required to properly compress the inner chevrons, without causing improper seating, premature seal failure, or oil leaks, and without requiring additional Government-funded teardowns or out-of-cycle replacements.
If no affirmative written responses demonstrating such capability are received by 10:00 AM Local Time on the notice end date, a solicitation will be issued that includes the brand-name material requirements. A determination by the Government not to compete this specific material requirement is solely within the discretion of the Government. Electronic responses shall be submitted via email to [email protected]. Oral communications are not acceptable. The U.S. Army Corps of Engineers is not responsible for any costs incurred by responding to this notice.
The U.S. Army Corps of Engineers, Walla Walla District, issued this special notice regarding the Little Goose Turbine Discharge Ring Upgrade and Blade Cavitation Repair project in Starbuck, Washington. The project requires the replacement of turbine blade runner packing seals across six main units to prevent lubricating oil leakage from Kaplan turbine hubs into the river. Under the authority of 10 U.S.C. 3204(a)(1), the government intends to specify James Walker brand Turbine Blade Runner Back-to-Back Packing as a brand-name requirement within a larger construction contract. This restriction is based on the need for proprietary dimensions and specific material compositions, including Type 3 and NM59-74/80 Acrylonitrile/butadiene based synthetic rubber, to avoid historical failure and environmental issues associated with alternative vendors.
The procurement is classified under NAICS 237990 Other Heavy and Civil Engineering Construction and PSC Z2KA REPAIR OR ALTERATION OF DAMS. There is no set-aside assigned to this action. While the government intends to solicit the primary construction action in November 2026, this notice seeks information from sources capable of providing alternative blade seals that meet exact fit, material, and dimensional requirements. Interested parties must submit a statement of capability with supporting laboratory testing and performance data to the designated point of contact, Chandra D. Crow, by May 14, 2026.
This notice of intent is identified by solicitation number W912EF26RSN17. The requirement consists of 36 seal stacks featuring proprietary shape dimensions and a nominal durometer of 80 IRHD. Responses must demonstrate that any proposed alternatives can match the precise strength and rigidity necessary to prevent improper seating or oil leaks without requiring additional government-funded repairs. If no capable sources are identified by the response deadline, the subsequent solicitation will proceed with the brand-name material specifications.
