UNSPSC 41113824: Soil head permeability tester

A tester that is needed for designing and constructing for dam body and drainage hole by knowing the uplift pressure on the structure installed underneath water, inundation area of base ground or dam body of earth dam, river bank, reclaimed dike.

UNSPSC 41113824 Soil head permeability tester is a Commodity code covering geotechnical testing equipment and construction materials testing and inspection services that state and local governments procure to assess soil properties, foundation conditions, and concrete/structural integrity during infrastructure and building projects. The recent solicitations show that actual buying under this code spans truck-mounted cone penetrometer testing units (CPT systems capable of soil sampling and subsurface characterization), electrical insulating oil testing services for utility equipment, and comprehensive materials testing and special inspection services for construction projects—from concrete compressive strength testing and soil compaction verification to reinforcing steel and welded structural inspections using ultrasonic and magnetic particle methods. Issuing bodies include state departments of transportation, municipal utility boards, city procurement offices, flood control districts, and town governments. The Michigan Department of Transportation, City of Key West (operating as Keys Energy Services), Town of Waterford Connecticut, City of Orlando, and Harris County Flood Control District appear among recent solicitors, indicating that materials testing and geotechnical characterization work is distributed across state transportation agencies, municipal utilities, local building departments, and regional water management authorities.

Recent activity concentrates in Florida, Michigan, Texas, and Connecticut. The Michigan Department of Transportation issued RFP 260000002268 on June 26, 2026 (due July 16, 2026) for a truck-mounted cone penetrometer test sounding unit, specifying a 20-ton system with integrated CPT push and pull capacity, dual data acquisition systems, and soil sampling equipment for geotechnical site characterization. The Town of Waterford, Connecticut released RFP 26009 on April 21, 2026 (due May 5, 2026) seeking materials testing firms to provide soil placement and compaction testing, concrete strength testing, reinforcing steel and structural steel inspections for a 10,000-square-foot fire station, with unit-price-based fees and no budget ceiling disclosed. Keys Energy Services (Utility Board of the City of Key West, Florida) issued dual solicitations for electrical insulating oil testing services—RFP 1026 posted April 6, 2026 (due April 17, 2026) and RFP 0426 (due February 23, 2026)—each requiring laboratory testing of power transformer and voltage regulator oil samples under ASTM specifications with three-year base contracts and optional renewals. The Harris County Flood Control District released RFSQ 260032 on January 30, 2026 (due March 2, 2026) seeking on-call construction materials engineering and testing services for stormwater detention, channel repair, and concrete-lined construction projects using a 100-point qualification-based evaluation rather than price-based award.
