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 pumps at the John Day Dam in Rufus, Oregon. Identified as solicitation number W9127N26BA001, this procurement is a total SBA (SBA) small business set-aside. The project is classified under NAICS 237990 Other Heavy and Civil Engineering Construction and PSC Z2KA REPAIR OR ALTERATION OF DAMS. Responses are due by May 20, 2026, to the attention of Kristel Flores.

The project scope involves the removal, refurbishment, and replacement of major components for Fish Pump Units 1, 2, and 3, including shafts, bearings, bearing brackets, and right-angle drive gearboxes. Work requires the field disassembly of existing equipment, transport of components for off-site shop repair, precision machining, and the fabrication of replacement parts. Specific technical objectives include the repair-by-replacement of 1000 horsepower class power transmission and reduction gearboxes, the installation of greaseless bearing liners, and the replacement of stainless-steel bearing journals. This effort replicates previous work performed on fish pump No. 3, which involved true-up machining of mounting flanges and spigot bores to achieve specified radial clearances.

Following refurbishment, the contractor will perform on-site reassembly, shaft alignment, and system balancing. The contract includes testing the completed pump units to verify functional performance and the delivery of updated operation and maintenance manuals, drawings, and spare parts. This solicitation was originally published on April 8, 2026, and includes 19 attachments, such as site visit rosters, technical drawings, and an abstract of offers.
