NIGP 90644: Heating; Ventilating; Air Conditioning - Architectural Services

NIGP 90644 Heating, Ventilating, Air Conditioning - Architectural Services, Item code, encompasses architectural and engineering design services for HVAC system planning, replacement, retrofit, and facility-wide mechanical system upgrades at state and local government buildings. Recent solicitations show state and local buyers procuring comprehensive A/E services spanning preliminary design through construction administration for heating and cooling system replacements, facility assessments, and integrated mechanical system modernization—not standalone HVAC procurement but rather the full design and engineering support required to scope, specify, and oversee HVAC improvements as part of larger facility or building renovation initiatives.

The buying mix spans state agencies (Texas Facilities Commission, Texas A&M University System, University System of Georgia), county governments (Bleckley County, Montgomery County, Pinellas County), cities (Cocoa, Madison, Santa Fe, Atlanta, Dallas, Gallup, Nicholls), special-purpose districts (West Basin Municipal Water District), and higher education institutions. Recent opportunities cluster in Georgia, Texas, Florida, and California, with additional activity in New Mexico, Pennsylvania, and Wisconsin.
