About this opportunity
The U.S. Army Corps of Engineers Rock Island District is soliciting bids for the fabrication and delivery of Tainter gates for Lock and Dam 21, located near Quincy, Illinois on the Mississippi River. The procurement involves the manufacturing, testing, painting, and delivery of ten Tainter gates, with an option to procure up to six additional gates pending fiscal year 2026 funding. Each gate is a highly engineered submergible tainter gate measuring approximately 60 feet in overall length with complex curved geometry and weighing approximately 189,000 pounds, constructed primarily of ASTM A709 Grade 50 steel. Bidders must meet stringent qualification requirements including AISC certification, welding qualifications, and specific material certifications for these hydraulic steel structures. The solicitation was originally posted on July 30, 2025, with Amendment 0001 extending the bid due date from September 2, 2025, to September 9, 2025, with bid opening scheduled for 11:00 AM Central Time on the final due date via Microsoft Teams teleconference.
This procurement is designated as a Total Small Business set-aside under NAICS code 332312 (Fabricated Structural Metal Manufacturing). The bid opening on September 9, 2025, received two proposals: Reagent World of Irvine, California submitted a bid of $12,494,750.50, while Sealevel Construction of Thibodaux, Louisiana bid $17,263,000.00, compared to the government's independent estimate of $14,461,588.76. The contract structure includes a firm-fixed-price arrangement with multiple line items covering gate fabrication, delivery, and barge demurrage, with delivery required within 1,200 calendar days after notice to proceed. Delivery restrictions apply between January 1 and March 30, and all work will be performed for the Lock and Dam 21 facility in Quincy, Illinois. The procurement involves fracture-critical structural components requiring precise fabrication tolerances and specialized manufacturing processes for controlling water flow at this critical Mississippi River navigation facility.
