The FAA seeks contractors to design, fabricate, and deliver outdoor metal equipment shelters for ALSF and Glide Slope systems at Portland International Airport (KPDX) in Portland, Oregon. Work includes indoor fabrication and equipment integration at the contractor’s own facility, with FAA access for inspections, followed by transport to the airport. To receive the full specification package, applicants must pass a screening evaluation by demonstrating relevant past performance and financial capability. Qualified offerors must have an active SAM.gov registration with NAICS code 332312 and provide documentation of aviation-related shelter projects completed within the last five years. No budget or performance timeline is specified; interested vendors should assess their ability to meet the mandatory go/no-go criteria.
