UNSPSC 32152000: Process control or packaged automation systems

Complete packaged systems that automate control of a process and typically deal with analog signals from sensors and meters that are transmitted to specialized computers which cause the temperature, pressure and flow to be continually adjusted. Process control makes extensive use of analog to digital and digital to analog conversion.

UNSPSC 32152000 Process control or packaged automation systems, Class, encompasses Programmable Logic Controller (PLC) replacements, SCADA system modernizations, building automation system upgrades, and digital valve positioners—work that state and local water utilities, municipal water districts, school districts, and energy facilities are actively procuring to modernize aging process control infrastructure. Recent solicitations show water treatment plants replacing legacy PLCs (Modicon 984s, General Electric iFix systems) with current platforms (Modicon M580, Schneider Electric AVEVA), integrating new HMI systems, upgrading network architecture from ControlNet to Ethernet/IP, and commissioning Factory and Site Acceptance Testing alongside operator training and comprehensive documentation. School districts are replacing building automation systems at secondary facilities, while municipal utilities are upgrading SCADA systems for process monitoring and automation across filtration, chemical treatment, and pump station operations. The issuing bodies include municipal water districts, city water departments, county school districts, independent school districts, municipal purchasing offices, and state agencies—with West Basin Municipal Water District, City of Atlanta Department of Watershed Management, Cherokee County School District, and the City of Austin Purchasing Office appearing as repeat recent buyers.

Geographic activity concentrates in Georgia (City of Atlanta's two concurrent SCADA improvement procurements at Hemphill and Chattahoochee Water Treatment Plants, both due October 14, 2026), Texas (West Basin Municipal Water District RFP for Torrance Refinery Water Recycling Plant PLC replacements due November 5, 2026; City of Austin IFQ for digital valve positioner due October 20, 2026; Northside Independent School District IFB for athletic equipment consolidating prior contracts, due October 19, 2026; City of Santa Fe RFP for BDD PLC and SCADA modifications with proposal deadline December 18, 2025), California, and Florida, with secondary activity in New Mexico and South Carolina. Representative current opportunities include West Basin's RFP (RFPDS0149) requesting proposals for replacement of three Modicon controllers with M580 processors, HMI screen development, and PLC programming following Schneider Electric EcoStruxure Control Expert standards at the Torrance Regional Water Recycling Plant facility with proposals due November 5, 2026; Cherokee County School District's RFP (BAU2027RFP) for building automation system replacements at two secondary schools due October 29, 2026; and the City of Atlanta's dual SCADA improvement opportunities (both IFBs due October 14, 2026) encompassing General Electric to Schneider Electric HMI migration, ControlLogix PLC installation, and network conversion across water treatment plants requiring demonstrated experience with comparable end-to-end integration projects and at least five years of relevant PLC and SCADA upgrade work.
