UNSPSC 41113824: Soil head permeability tester

A tester that is needed for designing and constructing for dam body and drainage hole by knowing the uplift pressure on the structure installed underneath water, inundation area of base ground or dam body of earth dam, river bank, reclaimed dike.

UNSPSC 41113824 Soil head permeability tester is a Commodity code that encompasses soil and geotechnical field testing equipment and related laboratory instruments for construction quality assurance. State and local governments use this code to procure proctor compactors, cone penetrometer testing (CPT) systems, and related soil analysis and permeability assessment equipment for transportation departments, utilities, and municipal construction programs. Issuing bodies include state transportation departments (notably the Michigan Department of Transportation and Texas Department of Transportation), county governments (Henry County, Georgia), and municipal utilities and public works departments (City of Key West, City of Augusta). Recent solicitations reflect demand for specialized field testing apparatus — both single-item purchases of major equipment and on-call materials testing services contracts that include soil testing as one service line among several.

Recent activity concentrates in the Southeast and Midwest. The Michigan Department of Transportation posted an RFP for a truck-mounted Cone Penetrometer Test sounding unit (RFP 260000002268), with proposals due July 16, 2026, and awarded to Applied Research Associates, Inc. at $1,011,529.00 pending State Administrative Board approval. Texas Department of Transportation is soliciting a Proctor Soil Compactor with Soil Analyzer and accessories (Solicitation 601340000067218) with responses due October 27, 2026 through the Bonfire Hub procurement platform. Henry County, Georgia issued an RFQ for on-call materials and field testing services (RFQ #27-08) due September 9, 2026, requiring GDOT prequalification and including soil compaction and soil cement testing among the scope. The City of Augusta, Georgia posted an RFP for geotechnical testing services (RFP 26-176) due September 11, 2026, specifying an estimated 65 Modified Proctor tests and 650 in-place soil density tests over five years. These contracts typically carry one-year base terms with renewal options and emphasize ASTM compliance, specialized certifications (Nuclear Density Gauge, ACI credentials, GDOT prequalification), and professional liability insurance requirements ranging from $1 million to $2 million.
