UNSPSC 41113817: Soil liquid limit tester

A tester that is used to measure the liquid limit of soil.

UNSPSC 41113817 Soil liquid limit tester is a Commodity code that encompasses soil testing equipment and associated laboratory and field analysis services. State and local governments procure soil compaction and analysis equipment, cone penetrometer test systems, and comprehensive geotechnical testing services including concrete and asphalt compressive strength testing, in-place soil density assessment, soil classification, and engineering consultation. Soliciting bodies include state transportation departments, municipal utilities, city public works departments, county purchasing offices, and special-purpose districts. The Texas Department of Transportation, Michigan Department of Transportation, and Henry County, Georgia appear as repeat buyers across recent opportunities. Work spans both equipment procurement (truck-mounted CPT systems, Proctor soil compactors with integrated analyzers) and ongoing on-call testing services structured as task orders or annual contracts with fee schedules.

Recent activity concentrates in Texas, Georgia, Florida, and Michigan. Representative opportunities include the Texas Department of Transportation's October 2026 solicitation (601340000067218) for a Proctor Soil Compactor with Soil Analyzer and accessories, responses due October 27, 2026; the City of Augusta, Georgia's RFP 26-176 for on-call geotechnical testing services for construction projects, due September 11, 2026, covering laboratory testing, field testing, and engineering support over a five-year contract term with estimated quantities including 65 Modified Proctor tests and 650 in-place soil density tests; Henry County, Georgia's RFQ 27-08 for on-call materials and field testing services, due September 9, 2026, requiring GDOT prequalification and covering compressive strength testing, asphalt analysis, and soil cement mix designs; and the Michigan Department of Transportation's RFP 260000002268 for a truck-mounted Cone Penetrometer Test sounding unit, awarded to Applied Research Associates, Inc. at $1,011,529.00 in July 2026. Keys Energy Services (City of Key West, Florida) issued two related RFPs for electrical insulating oil testing services in September 2026, though those opportunities fall outside the soil liquid limit tester code's primary scope.
