UNSPSC 41111635: Gage block comparator

A measurement device that compares and inspects gauge block with the gauge block for master-level.

UNSPSC 41111635 Gage block comparator is a Commodity code that in recent state and local solicitations encompasses high-precision metrology and surveying equipment used for pavement analysis, geodetic surveys, and precision inspection applications. The Illinois Department of Transportation dominates recent activity under this code, with two rebids for handheld 3D laser scanning systems designed for pavement profiler certification at the Illinois Certification and Research Track; these systems must meet metrology-grade specifications including 0.025 mm minimum accuracy, blue laser technology with 30+ laser lines, ISO 10360 and VDI/VDE 2634 Part 3 certification from ISO 17025 accredited laboratories, and software compatibility with Autodesk, Siemens, and PTC platforms. Beyond IDOT, the code captures solicitations by universities (University of Texas at Austin for Leica TS-60 total stations and precision surveying equipment), county governments (Marion County, Florida for radar systems), and municipalities (City of Pennsylvania for laser distance meters, City of Philadelphia for inspection supplies). The scope diverges from the nominal "gage block comparator" title—recent solicitations actually involve handheld 3D laser scanners, total stations, distance meters, and related precision instruments rather than benchtop gage blocks.

Recent activity concentrates in Illinois and Texas, with additional solicitations in Florida and Pennsylvania. The Illinois Department of Transportation posted a rebid (Solicitation 27494DOTFINADB53879, RFQ, due September 25, 2026) and an earlier FY27 procurement (Solicitation 26494DOTFINADB53475, due August 18, 2026) for high-precision handheld 3D laser scanning systems; both require established manufacturers or authorized dealers with proof of dealer status, newly manufactured equipment only, general liability insurance of $1,000,000 per occurrence and $2,000,000 aggregate, and compliance with 34 Illinois state certifications. The University of Texas at Austin issued an ITB (Solicitation 721-26091, due June 30, 2026) for a Leica TS-60 total station with precision retroreflectors and geodetic tripods for McDonald Observatory surveys, awarded on best value criteria under Texas Education Code Section 51.9335 with delivery desired by July 15, 2026. Marion County, Florida (Solicitation 26108, July 13, 2026) and the City of Philadelphia (Solicitation B2627187, May 27, 2026) posted micro purchases for specialized equipment and inspection supplies, respectively. The code shows modest but focused recent activity centered on transportation and higher-education precision-measurement needs.
