CO Skid Trailer Calibration

The Illinois Department of Transportation (IDOT) Central Office is soliciting a sole-source vendor for skid trailer calibration services, with proposals due July 21, 2026. This is a small purchase with sole-source conditions, which restricts competition to a single qualified provider.

The scope requires calibration services for IDOT's skid trailers, though the source does not detail the technical specifications, number of units, calibration frequency, or performance standards.
