UNSPSC 41113817: Soil liquid limit tester

A tester that is used to measure the liquid limit of soil.

UNSPSC 41113817 Soil liquid limit tester is a Commodity code with divergent application in recent state and local procurement activity. The code nominally describes laboratory apparatus for measuring soil plasticity, but the recent solicitations in the block show state and local governments actually procuring broader construction materials testing and geotechnical field services — including cone penetrometer testing rigs, comprehensive fire station construction materials inspection, electrical insulating oil laboratory testing, and on-call materials engineering and testing support for infrastructure projects. The issuing-body mix spans transportation departments, municipal building programs, utility authorities, and regional flood control districts. Michigan Department of Transportation, the Town of Waterford Connecticut, Keys Energy Services (City of Key West utility authority), the City of Orlando, and Harris County Flood Control District all posted opportunities within the past six months.

Recent activity concentrates in Florida (Key West and Orlando), Michigan, Connecticut, and Texas. The Michigan Department of Transportation issued RFP 5912600000022681 on June 26, 2026 (due July 16, 2026) seeking a truck-mounted Cone Penetrometer Test sounding unit with push, pull, and clamping capacity, data acquisition systems, soil samplers, and dilatometer and piezocone components for delivery to Lansing by August 20, 2026. The Town of Waterford Connecticut released RFP RFP26009 on April 21, 2026 (due May 5, 2026) for Special Inspector and materials testing services covering soil compaction, concrete strength testing, reinforcing steel and structural steel inspections, masonry testing, and fire protection system inspection for the Oswegatchie Fire Station project. Keys Energy Services in Key West issued RFP 1026 on April 6, 2026 (due April 17, 2026) and RFP 0426 on April 13, 2026 for annual electrical insulating oil testing across 28 transformer main tank units, 13 load tap changer units, and 10 voltage regulator units under a three-year base contract with two optional one-year renewals. Harris County Flood Control District posted an RFSQ for on-call Construction Materials Testing services on January 30, 2026 (due March 2, 2026) with enrollment in a five-year registry expected to begin April 2026, covering soil, concrete, steel, and channel construction testing across stormwater and flood control projects.
