UNSPSC 41113816: Consolidation tester

A tester that is used for the consolidation test that seeks the compression volume and compression speed when piling load, permitting the drainage toward the axis direction and restricting the soil surface.

UNSPSC 41113816 Consolidation tester is a Commodity code describing specialized soil and materials testing equipment that state and local governments procure for geotechnical and infrastructure assessment work. Recent solicitations under this code show demand for Proctor soil compactors with integrated analyzers, cone penetrometer test systems mounted on truck chassis, and related laboratory and field testing apparatus used to validate soil compaction, material properties, and structural integrity during highway, utility, and construction projects. State departments of transportation and county utilities departments are the primary issuing bodies, with support services procured by municipal utilities authorities and county engineering departments. The work involves both equipment acquisition and the operational testing services tied to that equipment—contractors often supply the apparatus alongside the labor and expertise to deploy it according to ASTM standards and state transportation guidelines.

Recent activity concentrates in the Southeast and Midwest, with the Texas Department of Transportation (TxDOT) posting a solicitation for a Proctor Soil Compactor with Soil Analyzer (due October 27, 2026), the Michigan Department of Transportation (MDOT) awarding a Cone Penetrometer Test truck-mounted sounding unit to Applied Research Associates, Inc. at $1,011,529.00 (notice issued July 22, 2026), and Henry County, Georgia issuing an RFQ for on-call materials and field testing services with a September 9, 2026 deadline. The City of Augusta, Georgia also solicited geotechnical testing services under RFP 26-176 (due September 11, 2026) covering Modified Proctor tests and in-place soil density work. Equipment purchases trend toward single-unit, high-value acquisitions (the Michigan CPT truck bid competitively), while jurisdictions increasingly structure testing services as on-call contracts with task-order pricing and GDOT or state agency prequalification gates. Bidders must hold current certifications—GDOT prequalification, AASHTO-certified laboratories, or authorized distributor status—and carry professional liability and equipment-specific insurance.
