UNSPSC 41113823: Specimen expansion tester

A tester that is designed to measure the expansion height following the time lapse for 96 hours as it is dipped in water with the defined load on the earth specimen produced with the pounding on mold.

UNSPSC 41113823 Specimen expansion tester (Commodity) describes equipment and related apparatus for laboratory and field soil and materials analysis, though recent state and local opportunities under this code solicited soil compaction and geotechnical testing instruments rather than specimen expansion testers narrowly construed. The work being bought includes Proctor soil compactors with integrated soil analyzers, cone penetrometer test (CPT) sounding units mounted on truck chassis, and comprehensive materials and field testing services encompassing concrete and soil compressive strength testing, asphalt extraction and density analysis, embankment and subgrade compaction testing, and soil classification. Issuing bodies span state transportation departments (Texas Department of Transportation, Michigan Department of Transportation), city utilities (Keys Energy Services in Key West, Florida), county governments (Henry County, Georgia; City of Augusta, Georgia), and municipal utilities departments. Repeat solicitation activity appears in Henry County and the City of Key West, with the latter posting two electrical insulating oil testing RFPs within two weeks in September 2026.

Recent activity concentrates in Georgia, Texas, Michigan, and Florida. TxDOT solicited a Proctor Soil Compactor with Soil Analyzer (IFB 601340000067218, due October 27, 2026); MDOT posted and awarded a truck-mounted CPT sounding unit (RFP 260000002268, awarded to Applied Research Associates, Inc. at $1,011,529.00 as of July 22, 2026, with an anticipated contract begin date of August 20, 2026); Henry County, Georgia issued RFQ #27-08 for on-call materials and field testing services (due September 9, 2026, requiring mandatory GDOT prequalification); and the City of Augusta, Georgia requested geotechnical testing proposals including Modified Proctor tests and in-place soil density testing (RFP 26-176, due September 11, 2026). The Keys Energy Services solicitations for electrical insulating oil testing (RFP 1026 due April 17, 2026, and RFP 0426 with an anomalously dated due date of February 23, 2026) represent activity outside the nominal scope of specimen expansion equipment but were tagged to this code in the source data.
