UNSPSC 81102700: Instrumented control systems design and engineering services

Includes a wide range of specialized control system design and engineering services

UNSPSC 81102700 Instrumented control systems design and engineering services is a Class code describing the professional engineering design and technical consulting work that state and local governments procure to plan, specify, and integrate automated control systems for water treatment and distribution infrastructure, electrical systems, SCADA platforms, and facility operations. Recent state and local solicitations under this code emphasize hydraulic modeling, treatment facility design, PLC and HMI system architecture, telemetry integration, and construction-phase engineering support across water districts, transportation authorities, counties, and municipalities. Municipal water districts and county utilities dominate recent activity, with West Basin Municipal Water District (California), the City of Tucson Water Department (Arizona), Orange County Utilities (Florida), and Tampa Bay Water (Florida regional authority) posting multiple active procurements. The geographic spread centers on Arizona, California, Florida, and Georgia, with activity across water and wastewater infrastructure modernization, emergency resilience projects, and asset management initiatives.

Recent representative opportunities include West Basin Municipal Water District's RFP for On-Call Professional Engineering Services (RFPTH0128), posted July 13, 2026, with proposals due July 14, 2026, seeking up to five firms for hydraulic modeling, treatment facility planning and design, SCADA and telemetry system design, and construction support services across a $3 million estimated value with time-and-material compensation and prevailing wage requirements; the City of Tucson's on-call RFQ for Electrical, SCADA Design, and Startup Services (250062) for water production facilities, targeting three firms for SCADA system design and electrical integration across a $7.5 million estimated annual budget with individual projects typically under $500,000; and Tampa Bay Water's as-needed engineering services RFP (2026046055), awarding a minimum of ten contracts at $1.25 million each for multistate consulting across instrumentation, controls, hydraulic modeling, and condition assessment across a five-year period. Orange County, Florida (Y26-900) and the City of Orlando (RQS250121) are actively soliciting continuing and on-call services for utility system controls and facility automation. Small business enterprise and local business enterprise set-asides and preference points appear in multiple recent solicitations, particularly in California and Florida procurements. The code sees steady activity across both design-phase and construction-administration work, with compensation structured through hourly labor rates, fixed fees negotiated per project, and lump-sum task orders.
