UNSPSC 41113827: Soil unconfined compression apparatus

A type of device that is used to determine the compression strength and sensitivity of soil.

UNSPSC 41113827 Soil unconfined compression apparatus is a Commodity code, but the recent state and local opportunities tagged under it center on construction materials testing and inspection services far broader than the apparatus itself — including concrete compressive strength testing, soil placement and compaction testing, reinforcing steel and structural steel inspections, masonry unit and mortar testing, and electrical insulating oil sampling and laboratory analysis. State and local governments procure these services through municipal public works departments, regional utilities, county flood control districts, and city capital improvement programs. The issuing bodies include county transportation departments, municipal engineering divisions, utility boards, and special-purpose districts responsible for stormwater and renewable energy infrastructure. The work is performance-based, with vendors engaged on both project-specific and on-call rosters, and success typically requires ASTM certification, state professional engineering licensure, ASNT non-destructive testing credentials, and ACI concrete certification for field personnel.

Recent activity clusters in Michigan, Florida, Texas, and Connecticut. The Michigan Department of Transportation issued RFP 5912600000022681 in June 2026 for a truck-mounted cone penetrometer test sounding unit with a July 16, 2026 response deadline, seeking a newly manufactured CPT system with 40,000-pound push capacity and integrated data acquisition on a specified chassis, awarded to the responsive and responsible lowest-price bidder meeting Pass/Fail criteria. The Town of Waterford, Connecticut, released RFP 26009 on April 21, 2026 for construction materials testing and Special Inspector services on the Oswegatchie Fire Station, closing May 5, 2026, with unit-price fixed-rate proposals covering soil compaction, concrete strength testing, steel and masonry inspections, and fire protection system testing. Keys Energy Services (City of Key West, Florida) issued separate RFPs in April 2026 for three-year electrical insulating oil testing contracts on multiple power transformers and voltage regulators, due April 17 and February 20, 2026, with annual January sampling and liquidated damages of $100 per day for missed February 1 completion deadlines. The Harris County Flood Control District issued an RFSQ in January 2026 for on-call construction materials engineering and testing services on stormwater and channel projects, closing March 2, 2026, governed by Texas Government Code 2254.004 qualification-based selection with enrollment in a five-year performance registry beginning April 2026 and M/WBE participation goals to be determined per project scope.
