NIGP 99234: Concrete Testing Services

NIGP 99234 Concrete Testing Services is an Item code encompassing independent materials testing, field inspection, and laboratory analysis of concrete, asphalt, soil, and related construction materials that state and local governments procure to verify compliance with design specifications and regulatory standards on infrastructure and building projects. State and local agencies — counties, cities, transit authorities, universities, and special-purpose districts — solicit these services both as standalone on-call testing contracts and as embedded quality assurance components of larger construction projects, frequently on an indefinite-delivery or as-needed basis where the scope and volume of work are not guaranteed upfront. Representative recent solicitations include Gwinnett County Board of Commissioners' BL089-26 (IFB, sealed bids due August 3, 2026) for comprehensive materials and field testing services including concrete, asphalt, soil, and non-destructive structural evaluation across the county on a one-year term with four renewal options; the City of Temple, Texas RFQ390127 (RFQ, SOQs due July 8, 2026) for independent third-party construction materials testing on an on-call basis for roadway, water utility, and vertical construction projects; and Harris County Flood Control District's RFSQ 260032 (RFSQ, qualifications due March 2, 2026) for on-call construction materials engineering and testing services supporting stormwater detention, channel repair, and bridge construction work, with selected firms enrolled in a five-year registry and compensation on a project-by-project basis.

Activity under the code spans the South, Southwest, and Southeast. Gwinnett County (Georgia), Harris County Flood Control District (Texas), the Cities of Temple and Dallas (Texas), Orange County (Florida), the City of Orlando (Florida), the City of San Antonio (Texas), the Texas State University System, and the Solid Waste Authority of Palm Beach County have all posted opportunities in the past six months. The Texas State University System RFQ for geotechnical, construction material testing, and environmental assessment services (RFQ 7582600096, qualifications due July 21, 2026) reflects a shift toward broader environmental assessment and geotechnical scope bundled with traditional concrete and materials testing. Work is predominantly delivered on-call or as-needed with no guaranteed minimum, though some jurisdictions award multiple vendors under a single solicitation to ensure adequate capacity and scheduling flexibility. Prevailing wage and Small Business Enterprise participation goals apply selectively — Gwinnett County's BL089-26 carries no set-aside, while San Antonio's River Walk staircase and sidewalk project includes 10-point SBE scoring bonuses. Insurance requirements typically demand $1–2 million general liability minimum, and selected vendors must hold current certifications such as AASHTO, A2LA accreditation, or state-specific prequalification (FDOT, TXDOT).
