John Day Fish Pump Rehabilitation W9127N26BA001

The U.S. Army Corps of Engineers Portland District intends to issue an Invitation for Bids (IFB) NO. W9127N26BA001 for John Day Fish Pump Rehabilitation Project. The rehabilitation project includes major mechanical rehabilitation work on large vertical turbine pumps associated with fish passage facilities at John Day Dam, located on the Columbia River near Rufus, Oregon. This requirement will address urgent reliability issues with the John Day South Fish Ladder turbine pumps. The project will include the removal, refurbishment, and replacement of major components of Fish Pump Units 1 and 2, including but not limited to shafts, bearings, brackets, and right-angle drive gearboxes. Work will require disassembly of existing equipment, transport of components for off-site shop repair, precision machining, fabrication of replacement parts, and final reinstallation and alignment to manufacturer specifications. The overall period of performance will be from June 2026 to December 2028 for physical completion of all work to include all options. The forthcoming solicitation is subject to the availability of funds. The solicitation will be available for download on or about 25 February 2026 with bids due 30 days after advertisement. This procurement is anticipated to be solicited as a Small Business Set Aside. The NAICS code for this procurement is 237990. The small business size standard is $45 million.

The U.S. Army Corps of Engineers (USACE) Portland District is soliciting a Contract for the John Day Fish Pump Rehabilitation at John Day Dam, Oregon. The proposed project will be a Total Small Business Set-Aside, firm-fixed price (FFP) contract. Background: Prior work on fish pump No.3 included replacement of the lower pump shaft, true-up machining of the upper pump shaft, true-up machining of the upper and lower bearing mounting flanges and spigot bores on the cover plate and diffuser, and true-up machining of the diffuser extension cone. The propeller itself had its blade tips built up with weld and re-machined a proper clearance (nominally 1/8" radial clearance) to the pit liner. In addition, the propeller center bores were true-up machined for proper fit (0.004-0.006" clearance) to the new lower shaft. The upper and lower bearings were fitted with greaseless bearing liners and the shafts existing stainless bearing journals were replaced with spares originally manufactured by Worthington Pump. work will be replicated for pump No.2 and possible pump No.1 and No. 3. Purpose: The project will include the removal, refurbishment, and replacement of major components of Fish Pump Units 1, 2 and 3, including but not limited to shafts, bearings, bearing brackets, and right-angle drive gearboxes. Work will require field disassembly of existing equipment, transport of components for off-site shop repair, precision machining, fabrication of replacement parts, and final reinstallation and alignment to manufacturer specifications. The following information represents the project objectives: Removal and replacement of damaged pump shafts and bearings. Repair-by-replacement of approximately 1000 horsepower class power transmission and reduction gearbox. Precision machining (true-up) of shafts, bearing housings, and diffuser components. Installation of greaseless bearing liners and replacement of stainless-steel bearing journals. On-site reassembly, shaft alignment, gearbox installation, and system balancing. Testing of the completed pump unit(s) to verify functional performance. Delivery of updated operation and maintenance manuals, drawings, and spare parts.
