About this file
This solicitation package includes plans and specifications for a construction project to upgrade the upstream unwatering sump system at McNary Lock and Dam. The project entails replacing one 50 HP unwatering pump, three 7.5 HP drainage pumps, and rerouting approximately 300 feet of 10-inch diameter discharge piping. An elevated fiberglass floor grating will also be installed. Work must be done in accordance with Corps of Engineers' safety requirements, and the contractor must develop submittals for quality control, safety, and closeout documentation. Bids are due as specified in solicitation W912EF20B0017, which was issued for this $1-5 million small business set-aside project located at McNary Dam in Umatilla, Oregon. The contractor will utilize the Corps' Resident Management System software and must have a Site Safety and Health Officer and CQC System Manager on staff meeting the qualifications outlined.
