John Day Fish Pump Rehabilitation

The U.S. Army Corps of Engineers Portland District is soliciting a firm-fixed-price contract for the rehabilitation of Fish Pump Units 1, 2, and 3 at the John Day Dam in Rufus, Oregon. This project involves the removal, off-site refurbishment, and reinstallation of major pump components, including shafts, bearings, bearing brackets, and right-angle drive gearboxes. Specific objectives include the replacement of damaged shafts, the repair-by-replacement of 1000 horsepower class power transmission and reduction gearboxes, and the installation of greaseless bearing liners and stainless-steel bearing journals. Work also requires precision machining of housings and diffuser components, on-site reassembly, shaft alignment, and performance testing to verify functional integrity.

This solicitation, identified by number W9127N26BA001, is a total Small Business Set-Aside (SBA). It is classified under NAICS 237990, Other Heavy and Civil Engineering Construction, and PSC Z2KA, Repair or Alteration of Dams. The response deadline for this opportunity was May 20, 2026, with an abstract of offers and final documentation published on May 21, 2026. Kristel Flores is the designated point of contact for this requirement.

The project documentation includes 19 total attachments, featuring amendments, a site visit roster, an abstract of offers, and technical diagrams such as fish pump room one-lines and hand drawings. The scope builds upon previous rehabilitation work performed on pump unit No. 3, which involved building up propeller blade tips with weld and machining center bores for proper fit. Final deliverables for the current contract include updated operation and maintenance manuals, as-built drawings, and spare parts.
