Shop Fabrication Inspection

For acceptance to ODOT material specifications, certain products must have a specific approval marking on them prior to shipment. The required marking is the result of an authorized pre-delivery inspection (commonly referred to as shop inspection) process. Inspections are for quality assurance purposes. Prior to production, contact Authorized Agents directly for details and instructions.
