The FAA is conducting a market survey to identify capable sources for manufacturing and delivering modular, transportable building units or shipping containers to Key West, Florida, to inform acquisition strategy and procurement planning. The baseline requirement is about 10 fully relocatable structural units with an approximate 30 ft × 48 ft assembled footprint, at least 8 ft interior clear height, R-28 insulated walls/roof, engineered for highway transit, crane rigging, rapid assembly, and compliant with the Buy American Act; FAA encourages alternative modularization and standard ISO container options. Delivery is targeted for February 1, 2027, with mandatory completion by February 28, 2027, subject to negotiation. Interested vendors are asked to provide preliminary capability statements covering technical capability, BAA compliance, manufacturing lead times and capacity, rough order of magnitude pricing, and company/vendor information. This is market research only, not an SIR/RFP, and findings may support future procurement under the Brand-New Air Traffic Control Initiative.
