Construction Audit Tracking System

Find instructions on using our construction and inspection audit system that will be used by WSDOT for all design build projects and other construction, testing and inspection processes.

The Construction Audit Tracking System (CATS) provides a communications process that allows WSDOT and contractors to resolve non-compliance issues found during construction inspections. This system is a new need to WSDOT and does not replace any existing computer systems at the agency.
