UNSPSC 41113820: Aggregate specific gravity tester

A tester that measures the specific gravity and absorption rate of thick aggregates. It is used for the analysis test of un-solidified concrete washing and it is structured of prevision specific gravity scale, steel wire for specific gravity measurement and water tank.

UNSPSC 41113820 Aggregate specific gravity tester is a Commodity code that covers materials testing equipment and services—particularly soil compaction assessment, concrete strength verification, asphalt and aggregate testing, and specialized geotechnical field instrumentation. Recent solicitations reveal state and local governments are buying both lab-grade testing apparatus and truck-mounted field equipment, often bundled with inspection and quality assurance labor during construction projects. The issuing bodies span state departments of transportation, municipal public works and utilities, county flood control districts, and city capital programs. Michigan Department of Transportation, Utah Department of Transportation, City of Orlando, Harris County Flood Control District, Town of Waterford Connecticut, and City of Key West Florida appear in the recent opportunity set, with particular concentration among state DOT procurement and municipal infrastructure construction support.

Recent opportunities tracked under this code include the Michigan Department of Transportation's June 2026 RFP for a truck-mounted Cone Penetrometer Test sounding unit with a July 16, 2026 deadline (RFP 260000002268); the Town of Waterford Connecticut's April 2026 RFP for materials testing and special inspector services for the Oswegatchie Fire Station with a May 5, 2026 due date; the Utah Department of Transportation's March and April 2026 IFBs for cover material (Type II chips) delivery across Region 1 and Region 3; the City of Key West's April 2026 RFP for electrical insulating oil testing services; the City of Orlando's February 2026 qualification statement request for material testing services supporting the Camping World Stadium Phase 3 project; and the Harris County Flood Control District's January 2026 RFSQ for on-call construction materials engineering and testing services with a March 2, 2026 deadline. Geographic spread includes Michigan, Utah, Connecticut, Florida, and Texas, with activity concentrated in state DOT procurement and municipal capital-project construction support. Competitive profile varies by opportunity type—some are low-bid IFBs, others are qualification-based RFSQs or best-value RFPs with multi-year on-call frameworks.
