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

NIGP 15586 Structures, Rooms, Panels, Enclosures, Etc. (Radio Frequency Shielded), an Item code, covers RF-shielded chambers and specialized electromagnetic containment structures that state and local governments procure for emergency response radio systems, engineering research, and security infrastructure. The code sees procurement activity across municipal, county, and state higher-education buyers acquiring turnkey RF shielding solutions for public safety operations and technical facilities. Recent solicitations show city fire and emergency services departments installing distributed antenna systems (DAS) and bi-directional amplifiers (BDAs) to enhance 700 MHz public safety radio coverage in municipal buildings, and universities acquiring RF-shielded chambers for engineering testing and research. The City of Phoenix has issued two five-year in-building radio frequency coverage contracts (IFB-26-0148 in April 2026 and a revised IFB-260355 posted July 17, 2026, with response due July 10, 2026) requiring turnkey Emergency Responder Radio Coverage Systems design, installation, and optimization across city buildings including three airports, with contractors demonstrating a minimum of three years of ERRCS/DAS/BDA experience and holding NICET certifications plus Arizona-licensed professional engineer credentials.

Recent activity concentrates in Arizona and Wisconsin, with secondary solicitations in Florida and Georgia for security and fire station construction incorporating RF elements. The City of Phoenix represents a repeat buyer, issuing two separate RF coverage contracts within four months. The University of Wisconsin-Madison posted two separate RF-shielded chamber RFBs in January and February 2026 (Event Numbers 2026-UWMSN-01215-RFB and 2026-UWMSN-01254-RFB, both posted within weeks of each other), suggesting either a rebid cycle or multiple chambers. Phoenix's contracts specify firm fixed pricing on a per-unit hourly basis for four labor categories (System Designer, Lead Installer/Project Management Lead/Testing Personnel, Installation Technician, Arizona-Licensed Professional Engineer), DBE compliance under 49 CFR Part 26, 12- to 24-month manufacturer's warranties, and emergency response performance obligations (four-hour response for routine service requests, 24-hour on-site support for critical failures). The Illinois Deaf and Hard of Hearing Commission procured a brand-name Whisper Room testing booth (solicitation 26444DHSBUSSEB52622, due May 27, 2026) for sign language interpreter certification at its Chicago location, completed by June 30, 2026, under prevailing wage requirements where applicable.
