UNSPSC 41113815: Soil shrinkage limit tester

A tester that measures the contraction limit of soil. The shrinkage limit of soil has its volume not reduced even if the water content of soil is reduced to certain volume or below, and if the water content is increased this device indicates the increase of volume which is shown in function ratio of limit.

UNSPSC 41113815 Soil shrinkage limit tester (Commodity) does not align with the state and local opportunities actually being procured under this code. The recent solicitations tagged to this code involve construction materials testing and inspection services—concrete compressive strength testing, soil compaction verification, reinforcing steel inspections, welded steel field inspections, and electrical insulating oil analysis—rather than shrinkage limit testing equipment. The code shows little relevant recent activity for its nominal scope; the mismatch between the code assignment and the work being bought suggests the tagging may reflect a data classification error rather than genuine shrinkage limit tester procurement.

The opportunities themselves span geographically dispersed state and local buyers. The Michigan Department of Transportation issued RFP 5912600000022681 (due July 16, 2026) for a truck-mounted Cone Penetrometer Test sounding unit; the Town of Waterford, Connecticut released RFP 26009 (due May 5, 2026) for materials testing and special inspection services for the Oswegatchie Fire Station; Keys Energy Services in Key West, Florida posted two electrical insulating oil testing RFPs (1026, due April 17, 2026, and 0426, due February 23, 2026); the City of Orlando sought qualifications for material testing services for Camping World Stadium Phase 3 (due October 29, 2025); and the Harris County Flood Control District in Texas issued RFSQ 260032 (due March 2, 2026) for on-call construction materials engineering and testing services. The issuing bodies include state departments of transportation, municipal utilities, city public works, counties, and special-purpose districts, with procurement ranging from RFP and RFSQ formats to firm pre-qualification processes.
