3D-PRINTING AND FABRICATION OF A PHYSICAL MODEL FOR LOCK AND DAM 25 NAVIGATION ECOSYSTEM SUSTAINABILITY PROGRAM (NESP)

The U.S. Army Corps of Engineers, St. Louis District, is soliciting qualified small businesses to fabricate a detailed 3D-printed physical model of the Lock and Dam 25 New 1200-ft Lock Project as part of the Navigation Ecosystem Sustainability Program. This model is intended to serve as a critical visual aid for communicating project scope, design, and benefits to a wide range of stakeholders including engineers, community members, policymakers, and the general public. The effort is structured as a total small business set-aside under NAICS code 339999, ensuring opportunities are reserved exclusively for small business concerns as defined by the SBA. All proposals must be submitted by August 24, 2026, through the SAM.gov portal with the solicitation number W912P926RA010. The work is to be performed at the agency’s location in Saint Louis, Missouri, with no specific place of performance outside this location indicated. Primary point of contact for inquiries is Catherine Hansen, reachable via phone or email, with Whitney Dee supporting as secondary contact. The model must accurately represent project components and be durable, scalable, and visually informative to meet outreach objectives. The contract is classified as combined, suggesting that both solicitation and award processes may occur under a single streamlined framework designed to facilitate efficient procurement. Applicants must demonstrate technical capability in precision 3D printing, model fabrication, and experience with large-scale engineering visualizations to meet the project’s rigorous standards.
