The Authorized Facility Audit List is intended to be part of the Department’s Quality Assurance program. When an entity other than the Department is performing quality verification acceptance activities, and per Deputy Directive 23 Revision 1(DD-23-R1), this entity is responsible for its own quality assurance program to ensure project components comply with Caltrans policies, standards, procedures, and best practices.
