UNSPSC 81101802: Chemical process engineering service

A service providing the design, operation, control, and optimization of chemical, physical, and biological processes through the aid of systematic computer-based methods.

UNSPSC 81101802 Chemical process engineering service is a Commodity code that state and local governments use to solicit design, permitting, and engineering oversight services for water and wastewater infrastructure projects—including wellfield expansion, treatment plant rehabilitation, and utility system assessments. Recent opportunities show municipalities and special districts contracting for preliminary engineering reports, final design, construction administration, and third-party technical review of complex water resource recovery facilities, with work spanning site investigation, process optimization, regulatory compliance coordination, and phased project delivery oversight.

The issuing bodies are predominantly municipal utilities departments, county water authorities, and special-purpose water districts across Florida, Georgia, Arizona, and Michigan. The City of Fort Myers, City of Tucson, Clayton County Water Authority, Pinellas County, and the Great Lakes Water Authority represent recent repeat activity. Representative opportunities include the City of Fort Myers RSQ 26-041 for design-build services on a potable water wellfield expansion (due July 8, 2026), Madison County, Georgia's RFQ for wastewater treatment plant upgrades and sewer line extension design (due June 24, 2026), the Great Lakes Water Authority's RFP for third-party design review of the Screened Final Effluent Rehabilitation project in Wayne County, Michigan (due February 13, 2026), and the City of Tucson's on-call RFQ for electrical, SCADA design, and startup services for water production facilities. Geographic activity concentrates in Florida and Georgia, with secondary opportunities in Michigan and Arizona. Most procurements are RFQs or RFPs weighted toward qualifications and past performance on similar infrastructure projects; compensation typically is negotiated on hourly rates, cost-plus-fixed-fee, or guaranteed maximum price structures, with individual project assignments authorized through task orders or work letters rather than fixed annual budgets.
