NIGP 92522: Control Systems Engineering

NIGP 92522 Control Systems Engineering, an Item code, encompasses the design, integration, and operational support of automated control systems for critical infrastructure, water and wastewater operations, traffic management, and facility automation. Recent state and local solicitations show government buyers procuring SCADA system integration and optimization, PLC and HMI upgrades for treatment plants, traffic signal operations programming, electrical control system design for lift stations and tunnels, and on-call control systems engineering across multiple disciplines. The issuing bodies span water utilities (Harris County Toll Road Authority, West Basin Municipal Water District, Eastern Municipal Water District, City of Waco, City of Tucson, Sarasota County), transportation authorities (Harris County Toll Road Authority, Georgia Department of Transportation, Sacramento County Department of Airports), municipalities (City of Dallas, City of Phoenix, City of Orlando), and special districts (Pinellas County School District, Walworth County). Water treatment and wastewater lift station hardening and control system replacement dominate the current pipeline, alongside traffic signal optimization programs and airport taxiway lighting and control upgrades. Harris County Toll Road Authority appears as a repeat buyer, soliciting both system-wide inspection services and segment design consulting for roadway and structural work under separate RFSQs posted in June and July 2026.
