UNSPSC 71171506: Laboratory testing service

Laboratory testing service means an independent entity engaged to perform specific inspections or tests, either at the project site or elsewhere, and to report and interpret the results of those inspections or tests.

UNSPSC 71171506 Laboratory testing service is a Commodity code that encompasses on-site and off-site materials testing, chemical and physical analysis of products, and inspection documentation for construction and infrastructure projects. State and local governments procure laboratory testing services primarily through special-inspection and materials-testing contracts tied to capital construction projects, deicer and product-quality verification programs, and environmental monitoring initiatives. Issuing bodies include state departments of transportation and facilities management, regional water authorities, solid waste authorities, and municipal governments. The scope spans concrete and soil compaction testing, asphalt verification, chemical analysis (active ingredients, heavy metals, corrosion inhibitors, pH levels), ISO 17025–certified deicer testing with twenty-three distinct test procedures, digester gas composition analysis, and specialized inspections for compliance with building codes and industry standards including ASTM, AASHTO, and AWWA. Work is performed both on-site during construction and in accredited laboratories off-site, with turnaround times typically ten days or less.

Recent activity shows a concentration of opportunities in Utah and California. The State of Utah Division of Facilities Construction and Management (DFCM) is the most active repeat buyer, posting two recent solicitations: a Request for Statement of Qualifications for code inspection firms (Solicitation DA26039, due June 3, 2026, with prequalification effective July 1, 2026–December 31, 2027) and an RFP for special inspections and testing services on the Loa Fish Hatchery project (Solicitation DA26023, due February 26, 2026, with an estimated budget of $280,000). The Utah Department of Transportation issued two Invitations for Bid for deicer testing services (UDOT IFB #DOT260177MP, originally due February 27, 2026, and subsequently reissued as UDOT260177MP1, due March 20, 2026), both structured as five-year requirements contracts with no guaranteed minimum volume and evaluation on weighted cost. The Eastern Municipal Water District in Riverside County, California, issued a Request for Proposal for long-term digester gas utilization project oversight including gas composition and quality testing (RFP 3900, due April 14, 2026). The Dalton-Whitfield Solid Waste Authority in Georgia issued an Invitation to Bid for landfill gas collection system construction and testing (ITB PE75552NONST2026000000061, due May 21, 2026). No set-aside designations are disclosed across these solicitations, though DFCM requires all special inspectors and testing labs to be pre-qualified and listed on its approved vendors list prior to award.
