The City of Spokane is soliciting qualifications from experienced engineering firms to provide on-call structural and mechanical design services for projects at the Upriver Dam, a Federal Energy Regulatory Commission-licensed hydroelectric facility. The selected firm will support a range of engineering activities including structural analysis, mechanical system upgrades, civil design, and construction phase services. Work may involve evaluation and rehabilitation of aging infrastructure such as spillways, gates, turbines, and concrete or steel structures, many of which date back to the original 1936 construction. Additional responsibilities include coordination with federal regulatory agencies, preparation of technical reports and compliance documentation, and support during bidding and construction phases. The contract is intended to provide flexible, as-needed expertise for multiple small to mid-sized projects over the contract term, ensuring compliance with regulatory standards and maintaining the safety and performance of the dam facility.
