NIGP 15586: Structures, Rooms, Panels, Enclosures, etc. (Radio Frequency Shielded)

NIGP 15586 Structures, Rooms, Panels, Enclosures, Etc. (Radio Frequency Shielded), an Item code, covers prefabricated and purpose-built enclosed structures, including radio frequency shielded rooms, emergency responder radio coverage systems with distributed antenna systems, shipping container enclosures, testing booths, and turnkey RF enhancement installations. State and local governments procure these structures for specialized facilities—emergency services infrastructure, corrections operations, public health testing, and critical communications—where RF shielding, environmental control, or containment is operationally essential. Issuing bodies include city capital delivery and finance departments, county fire services, state corrections and health agencies, and public health commissions. The mix skews toward municipal infrastructure projects funded through bond programs and state-level operational needs, with some competitive procurement and some brand-name or specification-limited solicitations.

Recent activity spans Florida, Texas, Arizona, and Illinois. The City of Phoenix Finance Central Procurement solicited in-building radio frequency coverage enhancement services (IFB-26-0355, responses due July 10, 2026) for a five-year contract across three airports with DBE-N compliance and NFPA 1225/UL 2524 standards. The City of San Antonio Capital Delivery Department posted Fire Station #33 Facility Replacement (RFCSP-26-071, proposals due July 30, 2026) and Hays Street Bridge Connections & Eastside Area Streets (RFCSP-26-025, proposals due August 25, 2026), both funded through the 2022 Bond and evaluated by city and departmental committees. The Texas Department of Criminal Justice requested bids for a shipping container roof kit and enclosure (IW-265496, bids due October 7, 2026). The Illinois Deaf and Hard of Hearing Commission pursued a brand-name Whisper Room testing booth for Chicago (proposals due May 27, 2026) with prevailing wage and insurance requirements. The City of DeBary procured construction services for Fire Station #3 (responses due March 30, 2016, closed/completed).
