UNSPSC 41113815: Soil shrinkage limit tester

A tester that measures the contraction limit of soil. The shrinkage limit of soil has its volume not reduced even if the water content of soil is reduced to certain volume or below, and if the water content is increased this device indicates the increase of volume which is shown in function ratio of limit.

UNSPSC 41113815 Soil shrinkage limit tester (Commodity) encompasses laboratory and field soil testing equipment and services that state and local governments procure for transportation, utilities, and infrastructure construction projects. Recent opportunities show state and local buyers acquiring both standalone soil testing instruments—such as Proctor compactors with soil analyzers—and comprehensive on-call materials testing services that include soil classification, compaction verification, and in-place density testing. The issuing bodies include state transportation departments, county utilities and public works divisions, municipalities, and regional utility authorities. Texas Department of Transportation, Michigan Department of Transportation, Henry County Georgia, the City of Augusta Georgia, and Keys Energy Services (City of Key West, Florida) appear as active buyers over the past two months, with Georgia counties showing repeat solicitation activity for multi-year on-call materials testing frameworks.

Recent activity concentrates in the Southeast and Midwest. The Texas Department of Transportation solicited a Proctor soil compactor with soil analyzer and accessories (solicitation 601340000067218, IFB due October 27, 2026). Henry County, Georgia issued two parallel RFQs for on-call materials and field testing services including compressive strength testing, asphalt analysis, and compaction testing (RFQ #27-08, qualifications due September 9, 2026), requiring GDOT prequalification as a mandatory eligibility gate. The City of Augusta, Georgia requested on-call geotechnical testing services covering soil analysis, concrete testing, and in-place density testing (RFP 26-176, proposals due September 11, 2026). Michigan Department of Transportation awarded a truck-mounted Cone Penetrometer Test sounding unit to Applied Research Associates, Inc. at $1,011,529.00 following an RFP (notice of intent to award July 22, 2026). Keys Energy Services in Key West, Florida issued two RFPs for electrical insulating oil testing services (solicitations 0426 and 1026, proposals due February 20, 2026 and April 17, 2026 respectively), a tangential service involving laboratory analysis but outside the core soil-testing scope of this commodity code.
