• Description:
• 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 critical component of this project is the replacement of the turbine blade runner packing seals across all six main units. These seals are essential to maintain a tight boundary and mitigate lubricating oil leakage from the Kaplan turbine hubs into the river. Due to historical quality control and dimensional tolerance issues with alternative vendors—which have led to premature failures, environmental hazards, and extended unit outages—the Government intends to specify the use of highly specific, proprietary materials: James Walker brand Turbine Blade Runner Back-to-Back Packing. The requirement consists of 36 seal stacks utilizing proprietary shape dimensions, Type 3 Acrylonitrile/butadiene based synthetic rubber headers, and NM59-74/80 Acrylonitrile/butadiene based synthetic rubber intermediate rings and glands with a nominal Durometer of 80 IRHD.
  The 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 construct...
