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

NIGP 91136 C.I.P., HVAC Balancing Services is an Item code covering testing, adjusting, and balancing (TAB) work for heating, ventilation, and air-conditioning systems at state and local facilities. State and local governments procure this work to optimize HVAC performance, verify design-intent operation, balance airflow and hydronic systems, and ensure occupant comfort and energy efficiency across diverse facility portfolios including municipal buildings, schools, universities, transit authorities, water and sewer districts, and specialized facilities. Recent solicitations reflect a mix of on-call and project-specific TAB services, from standalone balancing engagements to integrated commissioning and facility upgrades where TAB is a component deliverable.
