NIGP 03126: Control Systems: Complete (for Automatic Temperature Control)

NIGP 03126 Control Systems: Complete (For Automatic Temperature Control), an Item code, encompasses replacement and upgrade of direct digital control (DDC) and pneumatic-to-electronic conversion systems for HVAC terminal units, boiler and chiller equipment, and building automation integration in state and local facilities. State and local governments are soliciting for dual-duct terminal unit replacements with control conversion, boiler and chiller preventative maintenance and repair contracts requiring certified technicians, complete DDC system replacements using BACnet protocol to modernize legacy control infrastructure, and Building Management System (BMS) updates including sequence of operations, schematics, and equipment integration. Issuing bodies include state agencies (Georgia State University, Oregon Department of Transportation, State of Idaho), city transit and water authorities (Charlotte transit system, Phoenix Water Services), county school districts (Stephens County Board of Education), and county facilities management (Milwaukee County). The code draws activity from universities managing campus HVAC upgrades, transit authorities maintaining district heating and cooling systems, water utilities installing instrumentation and sensor controls, and K-12 districts bundling HVAC improvements with districtwide renovations.

Recent opportunities span Georgia, Oregon, Idaho, North Carolina, Arizona, and Wisconsin. Georgia State University posted an RFQ in October 2026 for replacement of dual-duct terminal units, temperature sensors, and electronic control conversion at the Clarkston Building, with quotes due November 12, 2026 and 95-day completion required between semesters. The City of Charlotte issued an RFP in September 2026 for preventative maintenance and repair services on Trane, Pulse, Aalon, Carrier, and Lochinvar chillers at CATS facilities, proposals due October 15, 2026. The Oregon Department of Transportation posted an ITB in August 2026 for HVAC controls replacement at Building A in Salem, replacing a 1997-era system with a BACnet DDC system controlling five controllers and 36 VAV units across two floors, estimated project cost $100,000 to $250,000, bids due September 17, 2026. The City of Phoenix Water Services Department issued a five-year IFB in August 2026 for pressure and temperature instrumentation equipment for municipal water and wastewater facilities, sealed offers due August 18, 2026, requiring vendors to function as local stocking distributors with same-day or next-business-day fulfillment capability.
