NIGP 84571: Strength of Materials Testing Apparatus (for Metals, Plastics, Wood, etc.): Fatigue Resistance, Hardness, Internal Flaws, etc.

NIGP 84571 Strength Of Materials Testing Apparatus (For Metals, Plastics, Wood, Etc.): Fatigue Resistance, Hardness, Internal Flaws, Etc. is an Item code under which state and local governments procure laboratory and field materials testing services, specialized testing equipment, and calibration and quality assurance work for construction materials, transportation infrastructure, utility systems, and facilities projects. Recent opportunities show a mix of direct equipment purchases—a precision high-voltage measurement module for utility testing, large-bed and small-bed compression machines for plastic pipe and concrete specimen testing, pan concrete mixers, and calibration services for load cells—alongside consulting contracts for geotechnical investigation, construction materials testing oversight, construction engineering and inspection work that includes materials sampling and testing responsibilities, and materials laboratory analysis supporting water infrastructure, roadway, bridge, and building projects. Issuing bodies span state departments of transportation (Georgia, Illinois), municipal utilities (Kissimmee, Fort Myers), county water and wastewater authorities (Wayne County, Michigan), city public works and utilities departments (Fort Myers, Rio Rancho), school districts (Dallas ISD), toll road authorities (Harris County), and special-purpose districts (Brazos River Authority, Indian River County). Georgia Department of Transportation and Illinois Department of Transportation appear repeatedly as active buyers across multiple solicitation types and project categories.

Geographic activity concentrates in the Southeast (Georgia, Florida) and Midwest (Illinois, Michigan), with secondary activity in Texas and scattered western jurisdictions. Representative recent opportunities include the Georgia Department of Transportation's RFQ for Independent Cost Estimator services for the I-285 East Express Lanes Project (PE48401RFQ2027000000632, due November 16, 2026), which embeds materials testing and quality control responsibilities within a broader alternative-delivery consulting contract; the City of Fort Myers' RSQ for Material Testing Services on a continuing basis (25054RSQ, due May 23, 2025), specifying field investigations, auger borings, laboratory testing, and construction quality control with 15% MBE participation goals and local-vendor preference points; the Kissimmee Utility Authority's IFB for a precision high-voltage capacitance and power/dissipation factor measurement module (IFB26046JG, due September 22, 2026); and the Illinois Department of Transportation's rebid for a large-bed compression machine for plastic pipe testing to AASHTO and ASTM standards (27494DOTFINADB53631, due September 9, 2026, open to all vendors in BidBuy). IDOT has also rebid calibration services for load cell equipment to ASTM E74 and AASHTO R18 standards with mandatory ISO/IEC 17025 accreditation (27494DOTFINADB53622, due September 15, 2026).
