UNSPSC 41113822: California bearing ratio tester

A soil tester that is used to determine the California bearing ratio of the subgrade soil by the penetration method in order to determine the bearing capacity of subgrade or roadbed.

UNSPSC 41113822 California bearing ratio tester is a Commodity code. State and local governments procure geotechnical and materials testing equipment under this code, including soil compactors, cone penetrometer systems, and related lab apparatus for construction and utilities inspection. Recent solicitations show demand for Proctor soil compactors with integrated soil analyzers, truck-mounted cone penetrometer test (CPT) sounding units with push/pull systems and data acquisition capability, and comprehensive field and laboratory testing services bundled with equipment procurement. The issuing bodies span state transportation departments (Michigan Department of Transportation, Texas Department of Transportation), county governments (Henry County, Georgia), municipalities (City of Augusta, Georgia; City of Key West, Florida), and utility authorities. State departments and counties appear as repeat buyers; TxDOT and Henry County each issued solicitations for materials testing services, while MDOT issued an RFP for a specialized CPT truck with manufacturer-grade specifications.

Recent activity concentrates in Texas, Georgia, Michigan, and Florida. The Michigan Department of Transportation issued an RFP for a truck-mounted CPT sounding unit (RFP 260000002268) due July 16, 2026, with award at $1,011,529.00 to Applied Research Associates, Inc. for a Vertek system on a Mack 6x4 chassis. The Texas Department of Transportation posted solicitation 601340000067218 (due October 27, 2026) for a Proctor Soil Compactor with Soil Analyzer and accessories, requiring CMBL registration and submissions via the Bonfire Hub platform. Henry County, Georgia issued RFQ #27-08 (due September 9, 2026) for on-call materials and field testing services including compressive strength testing, asphalt extraction and gradation analysis, and soil cement mix designs, with mandatory GDOT prequalification. The City of Augusta, Georgia issued RFP 26-176 (due September 11, 2026) for on-call geotechnical testing including Modified Proctor tests, in-place soil density testing, and engineering consultation over a five-year term.
