UNSPSC 41114616: Proofstress indicators

UNSPSC 41114616 Proofstress indicators is a Commodity code that covers specialized testing equipment and materials inspection services for construction and infrastructure projects, based on recent state and local solicitations. State and local governments procure this code primarily through construction engineering and inspection (CEI) services for transportation, water, and building projects, where materials testing and quality assurance are essential to verify compliance with design specifications and applicable standards. The issuing bodies span state departments of transportation (Georgia, Illinois, Florida), county and municipal engineering departments (Wayne County Michigan, Jackson County Georgia, Harris County Texas), cities (Orlando, Fort Myers, Dallas, Arlington, Austin, Rio Rancho), school districts (Dallas ISD, Alvin College), transit authorities (Harris County Toll Road Authority), and special-purpose water and flood-control districts (Great Lakes Water Authority, Harris County Flood Control District). A standout repeat buyer is the Georgia Department of Transportation, which posted multiple CEI and construction materials testing solicitations under related codes during the recent window.

Representative recent opportunities reflect the code's application across infrastructure segments. The City of Fort Myers issued RFQ RSQ26053 on July 2, 2026 (due July 2, 2026) for geotechnical engineering and construction materials testing services for the Fort Myers Police Department Headquarters project, including subsurface characterization, materials laboratory testing, field inspection, and compliance documentation. The Harris County Flood Control District issued RFSQ 260032 on January 30, 2026 (due March 2, 2026) for on-call construction materials engineering and testing services supporting the District's construction program, including stormwater detention, channel repairs, and concrete-lined channel construction. The Town of Waterford, Connecticut posted RFP 26009 on April 21, 2026 (due May 5, 2026) for special inspector services and materials testing for the Oswegatchie Fire Station construction, encompassing soil compaction tests, concrete strength testing, steel inspections, and masonry inspections. Georgia's Georgia Department of Transportation issued multiple CEI solicitations (RFQ PE48401RFQ2026000000599 and others) for construction engineering and inspection across state routes, requiring field testing of roadway materials and erosion control inspections. Recent activity concentrates in Georgia, Texas, Michigan, Florida, Connecticut, and Illinois, with ongoing demand for materials testing and quality assurance across highway, transit, water, building, and municipal infrastructure sectors.
