Solicitation
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.
