USACE Rock Island requires off-site fabrication and delivery of new bolted Tainter gates for Lock and Dam 21. The gates are approximately 20 feet high by 64 feet long and consist of cold-rolled shapes and welded assemblies. Welded assemblies must comply with AWS D1.1 and are designed without fracture-critical members to enhance structural reliability. Bidders should complete the Schedule of Prices, disregarding the omitted CLIN in Section B. USACE will post the Bid Abstract on 9/21/2026, and CADD model information is available by contacting joseph.e.porter@usace.army.mil.

USACE Rock Island requires fabrication and delivery of new bolted Tainter gates for Lock and Dam 21. The work includes off-site fabrication of gates measuring approximately 20 feet high by 64 feet long, made from cold-rolled shapes and welded assemblies. Welded assemblies must comply with AWS D1.1 and are designed without fracture-critical members for enhanced structural reliability. Bidders should complete the Schedule of Prices, which USACE will use, and disregard the omitted CLIN in Section B; no amendment will be issued, but CADD model information is available.

The project requires the off-site fabrication and delivery of new bolted Tainter gates for Lock and Dam 21. Each gate will measure approximately 20 feet high by 64 feet long, using cold-rolled shapes and welded assemblies. Welds must comply with AWS D1.1 standards, and the design has no fracture-critical members to improve reliability. Performance location is not specified, but the work is managed by USACE Rock Island. Contact joseph.e.porter@usace.army.mil to obtain the CADD model.
