NIGP 99236: Core Sample (Not Concrete) Testing Services

NIGP 99236 Core Sample (Not Concrete) Testing Services is an Item code under which state and local governments procure geotechnical investigation, materials testing, and quality-assurance services for capital projects—field sampling, laboratory analysis, inspection, and compliance documentation performed by licensed professionals to verify construction materials and subsurface conditions meet design and regulatory standards. The work spans auger borings, cone penetrometer testing, concrete and asphalt testing, aggregate inspections, soil compaction verification, and materials quality assurance across highway, utility, and facility construction programs. Issuing bodies include cities (Fort Myers, Tucson, Bradenton, Madison), counties (Washington County Oregon, Volusia County Florida, Bartow County Georgia, Orange County Florida), and special-purpose districts (Kissimmee Utility Authority); cities and counties dominate recent solicitation volume, with multiple repeat buyers (Fort Myers, Volusia County, Kissimmee Utility Authority) appearing across several concurrent procurements. Geographic activity concentrates in Florida (Fort Myers, Volusia County, Kissimmee, Orange County), the Pacific Northwest (Washington County Oregon), Arizona (Tucson), Georgia (Bartow County), Texas (Dallas), and Wisconsin (Madison), reflecting infrastructure investment across diverse regions.
