UNSPSC 41113827: Soil unconfined compression apparatus

A type of device that is used to determine the compression strength and sensitivity of soil.

UNSPSC 41113827 Soil unconfined compression apparatus, a Commodity code, encompasses soil testing and analysis equipment that state and local transportation, utility, and municipal engineering departments procure for geotechnical investigation, materials verification, and construction quality assurance. Recent solicitations show state and local buyers acquiring both compaction and compression testing apparatus—including Proctor soil compactors with integrated soil analyzers—alongside associated field and laboratory testing services for transportation projects, utility infrastructure, and site characterization work. Issuing bodies include state transportation departments (Texas Department of Transportation, Michigan Department of Transportation), county purchasing offices (Henry County, Georgia), cities and their utility authorities (City of Augusta, Georgia; City of Key West, Florida operating as Keys Energy Services), and municipal utilities. The code spans both equipment procurement and testing-service contracts that often bundle apparatus operation with reporting and consulting deliverables.

Recent activity concentrates in the South and Southeast. The Texas Department of Transportation posted solicitation 601340000067218 for a Proctor Soil Compactor with Soil Analyzer on October 6, 2026, with responses due October 27, 2026, requiring vendors to register on the Centralized Master Bidders List and submit through the Bonfire Hub platform. Henry County, Georgia issued RFQ #27-08 on August 12, 2026 (due September 9, 2026) for on-call materials and field testing services encompassing compressive strength testing, asphalt analysis, and soil compaction testing, contingent on GDOT prequalification. The City of Augusta, Georgia solicited geotechnical testing services under RFP 26-176 (due September 11, 2026) with estimated quantities including 65 Modified Proctor tests and 650 in-place soil density tests over five years. In Michigan, MDOT issued RFP 260000002268 for a truck-mounted Cone Penetrometer Test sounding unit (due July 16, 2026), with Applied Research Associates, Inc. receiving notice of intent to award at $1,011,529.00 on July 22, 2026. Keys Energy Services in Florida posted two electrical insulating oil testing solicitations (1026 and 0426) that diverge from soil compression scope, indicating some misclassification under this code in the recent dataset.
