About this opportunity
The U.S. Army Corps of Engineers, St. Louis District, seeks fabrication and delivery of a 3D-printed physical scale model of the Lock and Dam 25 New 1,200-Foot Lock Project, with proposals due August 24, 2026. The procurement is a Total Small Business set-aside under NAICS 339999 (All Other Miscellaneous Manufacturing) with a 550-employee size standard.
Place of performance is St. Louis, Missouri. The contractor must deliver a single complete model constructed at 1:200 scale with approximate footprint of 2.5 feet wide by 8 feet long, including existing lock structures, new lock chamber, gates, and a to-scale 15-barge tow configuration. The model must be segmented for transportability in a standard consumer SUV with each segment weighing no more than 50 pounds, feature functional miter gates, and meet demanding five-year indoor performance standards including dimensional stability, UV resistance, and non-brittle properties. The Government will furnish NavisWorks (NWD) and STEP format digital design files; the contractor must pre-process and convert these for fabrication. The performance period is 90 calendar days from award. All materials incorporated into the deliverable must be new and unused.
Evaluation is comparative and narrative-based across three equally-weighted factors: Technical Approach (pre-processing and file conversion capability, fabrication methodology, segmentation and transportability strategy, production schedule, and quality control); Past Performance (three to five references within five years, evaluated on recency, relevancy to large-format additive manufacturing with assemblies exceeding four feet and custom one-of-a-kind fabrication, and quality); and Price (reasonableness against Independent Government Estimate and realism assessment). Only verified small businesses will be considered. Proposals are submitted electronically via PIEE by 10:00 AM CST on August 24. Amendment 0001, posted July 31, added government responses to questions and updated Scope of Work, Quote Schedule, and Evaluation Factors documents. Questions regarding NavisWorks and Rivet files are due by 10:00 AM CST on August 12 to catherine.a.hansen@usace.army.mil.
