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 is a Commodity code that captures construction materials testing and inspection services state and local governments procure—including cone penetrometer testing equipment, electrical insulating oil sampling and laboratory analysis, and comprehensive materials testing for building construction projects involving concrete, steel, masonry, and soil testing. The work ranges from specialized geotechnical sounding units mounted on trucks to routine compliance inspections during fire station and stadium construction, and from electrical utility infrastructure testing to on-call quality assurance services supporting flood control and drainage projects. Issuing bodies include state transportation departments (Michigan Department of Transportation), municipal utilities (Keys Energy Services in Key West, Florida), municipal public works and building departments (Town of Waterford, Connecticut; City of Orlando, Florida), and special-purpose districts (Harris County Flood Control District, Texas). The code reflects a mix of one-time capital equipment purchases and recurring or project-based professional services.

Recent activity concentrates in Texas, Florida, Connecticut, and Michigan. Representative opportunities include the Michigan Department of Transportation's RFP for a truck-mounted Cone Penetrometer Test sounding unit with a response deadline of July 16, 2026, requiring a newly manufactured 20-ton system with specified hydraulic and data acquisition components; the Town of Waterford's RFP for Special Inspector and materials testing services for the Oswegatchie Fire Station (due May 5, 2026), requiring ACI, AWS, ICC, or ASNT-certified personnel and fixed unit pricing with no escalation permitted over the project period; Keys Energy Services' dual solicitations for electrical insulating oil testing on transformer and voltage regulator units (response dates February 20, 2026 and April 17, 2026), each with three-year base terms and optional renewals; the City of Orlando's qualification-based procurement for material testing services supporting the $270 million Camping World Stadium Phase 3 renovation (due October 29, 2025), restricted to Florida-registered engineering firms; and the Harris County Flood Control District's RFSQ for on-call construction materials engineering and testing services (due March 2, 2026), governed by Texas qualification-based selection rules and requiring A2LA certification with a five-year registry enrollment period beginning April 2026.
