UNSPSC 41113830: Aggregate unit weight measuring instrument

An instrument that is desired to measure the weight per 1 for the dried aggregates.

UNSPSC 41113830 Aggregate unit weight measuring instrument is a Commodity code whose recent state and local activity encompasses construction materials testing and inspection services across a wide range of civil and building infrastructure projects — soil sampling and compaction, concrete strength testing, structural steel and welded joint inspections, masonry unit and mortar evaluation, electrical equipment fluid analysis, and specialized subsurface soil characterization. State and local issuing bodies include county transportation departments, municipal governments, utility authorities, and special-purpose districts. The Michigan Department of Transportation's June 2026 RFP for a truck-mounted Cone Penetrometer Test sounding unit illustrates the deep subsurface testing end of the spectrum; the Town of Waterford, Connecticut's April 2026 RFP for Special Inspector and materials testing services on a new fire station exemplifies building-construction-focused testing; and the Harris County Flood Control District's January 2026 on-call construction materials engineering and testing RFSQ shows the procurement pattern for district-level infrastructure projects. A second thread of recent activity centers on specialized utility testing — Keys Energy Services in Key West, Florida posted two parallel RFPs in April 2026 for electrical insulating oil testing services covering transformer and voltage regulator equipment.

Geographic activity spans Michigan, Connecticut, Florida, and Texas in the most recent records, with utilities and special-purpose districts representing a meaningful share of recent buyers alongside traditional city and county procurement offices. The Michigan CPT sounding unit RFP (due July 16, 2026) targets a single specialized platform with stringent manufacturing and vendor qualification requirements; the Waterford fire station testing RFP (closed May 5, 2026) called for personnel certified by ACI, AWS, ICC, or ASNT with unit pricing locked for the project term; the Harris County on-call RFSQ (due March 2, 2026) used a 100-point qualification-based scoring system and enrolled selected firms in a five-year registry with compensation following the Harris County Fee Schedule; and the City of Orlando's stadium renovation testing services qualification statement (due October 29, 2025) targeted Florida-registered engineering firms with a $270 million construction budget. The Keys Energy Services oil testing solicitations (April 2026) were three-year base contracts with two optional one-year renewals, firm pricing except for annual CPI-capped adjustments, and liquidated damages of $100 per day for missed completion dates.
