About this opportunity
The US Army Corps of Engineers Engineering District Walla Walla is soliciting proposals for the Lower Granite Dam Turbine Intake Gate Hydraulic System Upgrades, a comprehensive project to replace and upgrade the existing hydraulic systems across six main units at the Lower Granite Dam facility. The project involves providing 19 new hydraulic cylinder assemblies (18 for installation and one spare), new hydraulic power units, control stations, distribution headers, flexible hoses, electrical controls, and associated components, along with removal and disposal of existing equipment. The work will be executed in three phases: pre-main unit outage, main unit outage, and post-main unit outage, with strict operational constraints to minimize disruption to dam operations. Proposals will be evaluated using a best value tradeoff approach with three criteria: Technical Approach (40%), Past Performance (40%), and Price (20%). The current proposal deadline is August 6, 2025, following multiple amendments that have extended the original submission date and updated technical specifications.
This procurement is designated as a Total Small Business set-aside under NAICS code 237990 (Other Heavy and Civil Engineering Construction). The contract will be a firm-fixed price construction contract with an estimated value between $10 million and $25 million, with performance spanning from August 2025 to April 2028. Key technical specifications include a system rated pressure of 3000 psi, normal operating pressure of 2000 psi, and gate closing speeds of 12 feet per minute, requiring 9,150 gallons of environmentally acceptable hydraulic fluid. The work will be performed at the Lower Granite Lock & Dam located at 885 Almota Ferry Road in Pomeroy, Washington, with a mandatory site visit having been conducted on April 24, 2025, which attracted sixteen representatives from various companies including Pacific Marine Equipment, Northbank Civil and Marine, Atomic Electric Inc, and Bosch Rexroth. The project includes extensive cybersecurity requirements for control systems and mandates comprehensive testing protocols, training for government personnel, and detailed documentation.
