NIGP 91136: C.i.p., HVAC Balancing Services

NIGP 91136 CIP, HVAC Balancing Services, Item, encompasses commissioning, testing, adjusting, and balancing (TAB) work on heating, ventilation, and air-conditioning systems to verify operational performance, airflow distribution, temperature control compliance, and system efficiency across state and local facilities. State and local governments soliciting under this code range across county facilities (Gwinnett County, Marion County, DeKalb County in Georgia; Orange County, Florida), municipal governments (City of Detroit, City of Tucson, City of Atlanta, City of Port Wentworth), school districts (Fulton County Schools, DeKalb County School District, Atlanta Public Schools), transit or special-purpose authorities (Madison Metropolitan Sewerage District, Texas Tech University, Sam Houston State University, Valencia College), and fire and emergency services (Tualatin Valley Fire & Rescue in Oregon). The code sees substantial recent activity across the Southeast, Southwest, and Upper Midwest, with Georgia, Florida, Michigan, Arizona, and Texas showing multiple concurrent solicitations.

Recent opportunities cluster around three work patterns: standalone TAB contracts for existing systems (San Mateo County's on-call HVAC testing and balancing RFP due May 27, 2026, at $150,000 aggregate; River Authority's TAB services for New Sheridan Campus due July 16, 2026), HVAC replacement and upgrade projects that include TAB as a component (City of Detroit's design-build rooftop unit replacement and Hart Plaza HVAC replacement, both RFPs due in October 2026; Atlanta Public Schools' Center for Learning and Leadership systems upgrade design-build, RFP due September 15, 2026), and integrated maintenance contracts that bundle preventive maintenance, repairs, and system balancing (Tualatin Valley Fire & Rescue's multi-award price agreement for 34 fire stations and 3 corporate buildings, quotes due November 2, 2026; DeKalb County School District's HVAC water treatment and balancing across 98 facilities, RFP due October 22, 2026). The code attracts both standalone TAB specialists and full-service mechanical contractors offering balancing as part of broader HVAC service. Most recent work requires EPA refrigerant certifications, state HVAC contractor licensing, and insurance minimums of $1 million commercial general liability; many jurisdictions impose prevailing wage and union labor compliance in states such as Oregon, California, and Georgia where applicable by statute.
