UNSPSC 41113812: Ground friction tester

A test that handles the friction, abrasion and lubrication of two sides that make contact and move around relatively.

UNSPSC 41113812 Ground friction tester is a Commodity code that encompasses soil and construction materials testing equipment and services, though recent state and local solicitations reveal the code captures a broader range of geotechnical and structural inspection work than the abstract name suggests. State and local governments use this code to procure truck-mounted cone penetrometer test systems, electrical insulating oil laboratory testing, construction materials inspection and testing services, and on-call materials engineering support for infrastructure projects. The issuing bodies span state departments of transportation, municipal utilities, city public works and capital projects offices, counties, and special-purpose districts managing flood control and infrastructure. Solicitations reflect procurement demand from transportation agencies, utilities, municipalities undertaking major construction, and regional districts managing multi-project engineering programs.

Recent activity appears concentrated in Florida, Michigan, and Texas, with secondary activity in Connecticut. The Michigan Department of Transportation (MDOT) posted RFP 5912600000022681 on June 26, 2026, seeking a truck-mounted Cone Penetrometer Test sounding unit with proposals due July 16, 2026; MDOT specifies Vertek CPT equipment on a Mack or Peterbilt chassis with 40,000 lb. push and 50,000 lb. pull capacity, assembled in the United States, and supplied by a single vendor with prior USDOT deliveries. Keys Energy Services, operating as the Utility Board of the City of Key West, Florida, posted two separate RFQs for electrical insulating oil testing in April 2026 (RFP 1026 due April 17, 2026, and RFP 0426 due February 23, 2026), each seeking three-year contracts with optional renewals covering annual and biannual testing of power transformers and voltage regulators. The Town of Waterford, Connecticut, issued RFP 26009 on April 21, 2026, due May 5, 2026, requesting materials testing firms to provide comprehensive inspection and testing services for construction of a 10,000-square-foot fire station, including concrete compressive strength testing, welded steel inspections using ultrasonic and magnetic particle methods, and masonry unit testing. The Harris County Flood Control District, Texas, posted RFSQ 260032 on January 30, 2026, due March 2, 2026, seeking on-call construction materials engineering and testing services using a qualification-based selection under Texas Government Code 2254.004, with evaluation on firm experience, capacity, and project methodology; the City of Orlando issued RQS 25-0611 on February 20, 2026, seeking qualification statements from Florida-registered engineering firms for material testing services on Camping World Stadium Phase 3, a $270 million renovation project.
