UNSPSC 41113906: Permeability or porosity estimation apparatus

UNSPSC 41113906 Permeability or porosity estimation apparatus, a Commodity code, covers soil compaction and testing equipment—particularly Proctor compactors with integrated soil analyzers and cone penetrometer test (CPT) sounding units—that state and local transportation, utility, and public works departments use to assess soil density, compaction, and subsurface conditions for construction and infrastructure projects. The code also captures electrical insulating oil testing apparatus and related laboratory services for utility power equipment. Issuing bodies span state transportation departments (Texas, Michigan), county public works and utilities (Henry County, Georgia), municipal utilities (City of Key West), and city public infrastructure departments (Augusta, Georgia). The work being solicited ranges from equipment procurement (truck-mounted CPT systems, soil compactors with analyzers) to comprehensive on-call testing services (geotechnical field and laboratory testing, electrical insulating oil sampling and analysis).

Recent activity concentrates in Georgia and the Southeast, with notable solicitations in Texas, Michigan, and Florida. The Texas Department of Transportation posted an IFB on October 6, 2026 (due October 27) for a Proctor Soil Compactor with Soil Analyzer, requiring vendors to register on the Centralized Master Bidders List and submit through the Bonfire Hub platform. The Michigan Department of Transportation awarded an RFP on July 22, 2026 to Applied Research Associates, Inc. for a truck-mounted CPT sounding unit at $1,011,529.00 after the original RFP posted June 26 with a July 16 due date. Henry County, Georgia issued an RFQ on August 12 (due September 9) for on-call materials and field testing services requiring GDOT prequalification, with scope including compressive strength testing, asphalt analysis, and embankment compaction work. The City of Augusta, Georgia solicited geotechnical testing services through an RFP on August 16 (due September 11) covering laboratory and field testing with estimated quantities of 65 Modified Proctor tests and 650 in-place soil density tests over five years. Keys Energy Services (City of Key West, Florida) issued duplicate RFPs in September 2026 for multiyear electrical insulating oil testing services for power transformers and voltage regulators, with sealed proposals due February 20 and April 17, 2026 respectively, requiring comprehensive laboratory analysis per ASTM specifications, IATA-compliant sampling, and 10-year data portal maintenance.
