AI Contract Overview
The U.S. Army Corps of Engineers is seeking industry input through a Request for Information to inform the fabrication approach for roller gates at the Winfield Lock and Dam in Red House, West Virginia, under solicitation number W91237-26-Q1C5L. Interested contractors are invited to respond to eleven detailed technical and economic questions covering welding methods, including submerged arc welding for skin plate splices, the impact of fabricating one versus multiple gates on economies of scale, labor savings from eliminating grinding of welds, and the implications of not staggering splice locations. Additional inquiries explore the feasibility of using bolted versus welded connections for skin plate splices, end shields, and aprons, the cost and logistical impact of 100% radiographic testing, production rates, and the potential benefits of modular design with multiple sub-assemblies requiring full shop fit prior to shipment. The RFI also examines the preference for supply-only fabrication contracts versus construction contractor roles and the cost differences between bearing type and slip-critical bolted connections. Responses are being solicited to help the agency reduce uncertainty and risk in future bidding and contract award, with specific questions addressing whether field final assembly would improve fabrication efficiency and what measures the U.S. Army Corps of Engineers could take to make bidding more predictable and less contingent on assumptions. The solicitation is open to all eligible contractors without set-aside restrictions under NAICS code 332312, with responses due by August 3, 2026, and technical drawings provided to guide submissions. Contracting personnel at the Huntington District office are available for direct inquiry, and all input will be used purely to refine procurement strategy—not as a binding solicitation or competitive bid process.

Full Description
This Request For Information Notice is intended to garner industry input for questions regarding Roller Gate Fabrication for the Winfiled Lock and Dam Located in Red House, West Virgina.
Interested Contractors are encouraged to reply to the following questions after reviewing the Attached Technical Drawings:
1. Can the skin plate splices be performed using submerged arc welding?
2. Economies of scale: Are there significant efficiencies related to fabrication of 1 gate v 2 gates v 3 gates, etc.
3. Not grinding skin plate welds—What is the time and labor savings? Would not staggering skin plate splices increase efficiency/benefit fabrication? Note that splice welds would still be required to be ground flush at the intersections of longitudinal and transverse splice welds a minimum of 4” in all directions.
4. What factors do you consider when doing 100% RT on this quantity of welds? Shutting down shop? How is this cost factored in? What is the production rate? Cost per test?
5. Would a design featuring multiple pieces (2-4) with transverse gate splice(s) benefit fabrication? Would you prefer this splice be welded or bolted using slip critical bolted connection. Note that full assembly would be required at the shop prior to shipment for a full shop fit assembly.
6. Would a design featuring bolted on end shields and/or apron benefit fabrication/increase efficiency?
7. Would you be more or less likely to bid if this was a Construction Contractor (i.e. working with a prime contractor to install) vs a supply fabrication contract.
8. What can USACE do to reduce risk/contingency in bidding a project like this?
9. Are there connections that would be more cost efficient bolted instead of welded? Would it be more cost efficient to weld, or use slip critical bolts to connect splices on the skin plate(longitudinal and transverse)?
10. Are there a fabrication cost difference between bearing type and slip-critical bolted connections.
11. If final assembly of the gates is allowed in the field during installation, is this something that would be a benefit for fabrication/increase efficiency?
