Bonneville spillway gantry crane rehabilitation

The U.S. Army Corps of Engineers Portland District is soliciting a firm fixed-price design-build contract for the rehabilitation of two 350-ton spillway gantry cranes at the Bonneville Dam. The project involves comprehensive rehabilitation of nearly 90-year-old Cranes 5 and 6, including structural, mechanical, and electrical upgrades to improve reliability and safety while maintaining gate splitting and lifting capabilities. This two-phase procurement will use a best value trade-off source selection process, with evaluation criteria including past performance (examining project relevance, recency, and quality), management approach focusing on technical skills and subcontractor management, technical approach for design-build, small business commitment, and price. The technical approach serves as the most important evaluation factor, while small business commitment is weighted as the least important. The original Phase I proposal deadline was extended from July 10, 2025 to July 28, 2025, with up to five of the most highly qualified offerors selected to proceed to Phase II and final contract award anticipated in September 2025.

This procurement is conducted as an unrestricted, full and open competition with no set-aside designations, though it includes a 10% HUBZone price evaluation preference in accordance with FAR 19.1307. No incumbent contractors are identified in the solicitation documents. The total contract value is estimated between $10 million and $25 million, falling under NAICS code 237990 (Other Heavy and Civil Engineering Construction) with a small business size standard of $45 million. The project requires maintaining one crane operational during fish passage periods and includes optional work such as inspecting and refurbishing components like hoist drums, lifting beams, roofing panels, and repainting. The work will be performed at the Bonneville Dam located in Skamania County, Washington and Multnomah County, Oregon, with the contractor responsible for design, execution, testing, and warranty of the crane rehabilitation. The solicitation mandates a minimum 10% small business commitment of the total contract value across various socioeconomic categories including Small Disadvantaged Business, Veteran-Owned Small Business, and HUBZone businesses.
