UNSPSC 81101600: Mechanical engineering

UNSPSC 81101600 Mechanical engineering is a Class code covering design, consulting, and engineering support services that state and local governments procure for mechanical systems in buildings, infrastructure, and facilities. Recent solicitations show state and local agencies buying preliminary design, full design development, construction administration, equipment specification, system optimization, and feasibility analysis across HVAC, plumbing, mechanical equipment, and renewable energy systems — work that often runs alongside architectural and civil engineering disciplines on multi-disciplinary task orders.

Issuing bodies span counties (Orange County, California and Florida; DeKalb County, Georgia; Pinellas County, Florida), cities (Orlando, Stamford, Berlin, Social Circle), school districts (Harlandale ISD, Somers Public Schools, Pinellas County Schools), special districts (West Basin Municipal Water District, Central Florida Tourism Oversight District, Solid Waste Authority of Palm Beach County), state agencies (Texas A&M University System, Georgia Department of Transportation, Missouri Office of Administration, Texas Facilities Commission), and higher-education institutions (Lamar University, Florida State College at Jacksonville). County public works departments and water utilities appear repeatedly as repeat buyers of on-call and task-order engineering services. Geographic activity spans California, Texas, Florida, Georgia, Connecticut, Oregon, and the upper Midwest. Representative recent opportunities include the State of Utah Division of Purchasing's RFP SB26-6 for construction project management services (response deadline August 20, 2026); West Basin Municipal Water District's RFP RFPTH0128 for on-call professional engineering services spanning water, wastewater, and recycled water systems (due July 14, 2026); Orange County, California's RFQ for A-E flood control engineering services (due August 13, 2026); and Palm Beach County Water Utilities Department's multiple RFPs for wastewater continuing engineering services, general utility and architectural services, and emergency/disaster mitigation engineering (proposals due July 7–9, 2026). Compensation structures are predominantly time-and-materials with hourly labor rates by classification or fixed-fee task orders; most contracts run three to four years with no guaranteed minimum work volume. SBE, MBE, and HUB participation goals apply across most recent solicitations.
