UNSPSC 81101531: Sanitation engineering service

A service that includes planning advisory and consulting, design, management, analysis and development of options and solution technologies in problems such as poor hygiene and environmental pollution, preparation of studies or related proposals, etc.

UNSPSC 81101531 Sanitation engineering service is a Commodity code that names independent cost estimating, design consulting, construction engineering and inspection, and facility assessment services across infrastructure modernization and development projects in state and local procurement. Recent solicitations show state and local governments buying engineering design and pre-construction support for water treatment and wastewater systems, stormwater and drainage improvements, pedestrian and transit infrastructure, roadway rehabilitation, and municipal facility expansion — work that blends architecture, civil engineering, environmental compliance, and construction administration into single integrated engagements. The issuing bodies soliciting under this code include Georgia Department of Transportation, Cobb County Department of Transportation, El Paso County Hospital District, City of Atlanta Department of Parks and Recreation, City of West Linn, Texas State University, City of Winder, Orlando Utilities Commission, University of Texas at El Paso, City of Fort Myers, City of Phoenix, and other counties, cities, school districts, and special districts across the Southeast, Southwest, and Pacific Northwest. Repeat buyers in the sample include Georgia DOT (two independent cost estimator RFQs for P3 and alternative delivery projects in 10 days), Cobb County and City of Atlanta (pedestrian bridge and trail design), and City of Fort Myers (stormwater and drainage, MEP design services).

Georgia DOT posted an RFQ on October 16, 2026 (due November 16) for Independent Cost Estimator services supporting the I-285 East Express Lanes Project using Design-Build-Finance-Operate-Maintain delivery; Cobb County posted an RFQ on October 16 (due November 12) for engineering design of the Factory Shoals Pedestrian Bridge Phase 1 requiring GDOT prequalification in six area classes; City of Atlanta posted a design RFP on October 5 (due November 6) for the Chastain Park Parking Garage with 25% MBE and 10% FBE joint venture requirements and a $500 million lump-sum cost allowance; and City of Fort Myers posted RSQ 26-031 on October 9 (due October 28) for closed drainage system design on Carrell Canal with 5% local vendor preference and 13% MBE scoring. Geographic spread centers on Georgia (GDOT, Cobb County, City of Atlanta, City of Winder, multiple CDBG projects in small counties), Florida (Fort Myers, Pompano Beach, Daytona Beach, Monroe County, multiple water and wastewater utilities), and scattered activity in Texas, Oregon, Utah, New Mexico, and the broader Southeast. The recent-opportunity mix reflects strong design-build and alternative delivery demand in public infrastructure (water, wastewater, stormwater, roads, transit) with mandatory prequalification filters, federal compliance overlays (Davis-Bacon, DBE, FEMA grant requirements), and persistent emphasis on local-vendor and minority-business scoring.
