UNSPSC 41113813: Standard aggregate

An aggregate sample that is defined for several properties to compare and test the capability and properties of aggregates.

UNSPSC 41113813 Standard aggregate (Commodity) covers materials testing and inspection services for construction and infrastructure projects, grounded in what state and local governments are actually procuring: soil compaction and sampling verification, concrete strength testing, reinforcing steel and structural welding inspections using nondestructive methods, masonry unit and mortar analysis, electrical insulating oil laboratory testing per ASTM specifications, and specialized geotechnical equipment such as truck-mounted Cone Penetrometer Test systems. The issuing-body mix includes state transportation departments, municipal public works and utilities, county flood-control districts, town building departments, and special-purpose authorities. State departments of transportation and county infrastructure agencies appear most active; the Harris County Flood Control District and Michigan Department of Transportation both have posted solicitations in the first half of 2026, and the City of Key West (operating Keys Energy Services) has issued multiple RFPs for electrical insulating oil testing services within the same window.

Recent opportunities span Michigan, Connecticut, Florida, and Texas. The Michigan Department of Transportation issued RFP 5912600000022681 (posted June 26, 2026, due July 16, 2026) for a truck-mounted Cone Penetrometer Test sounding unit with detailed equipment and chassis specifications, F.O.B. Destination pricing, and single-vendor delivery to Lansing. The Town of Waterford, Connecticut, solicited proposals via RFP 26009 (posted April 21, 2026, due May 5, 2026) for Special Inspector and materials testing services on the Oswegatchie Fire Station construction, requiring ACI, AWS, ICC, or ASNT certifications and unit-price billing with fixed rates for the project duration. The Harris County Flood Control District issued RFSQ 260032 (posted January 30, 2026, due March 2, 2026) for on-call construction materials engineering and testing across stormwater and channel projects, with evaluation based on firm qualifications and methodology under Texas Government Code 2254.004, a five-year registry enrollment upon selection, and projects awarded competitively from the qualified roster. Keys Energy Services (City of Key West) posted two electrical insulating oil testing RFPs in April 2026, one due February 23 and one due April 17, both for three-year base terms with optional one-year renewals covering annual testing of transformer main tanks, load tap compartments, and voltage regulators.
