This is part of the Oregon Department of Transportation's effort to ensure quality control and quality assurance for the construction of transportation facilities.
We provide training and resources for construction inspectors to ensure consistent administration of highway construction projects. Certified instructors safeguard compliance with contract documents and workmanship on ODOT construction projects.
The Inspection Certification Program document outlines the certification program elements and intent.
Full time inspectors are required to pass the General Inspector Certification exam and required discipline certifications, as needed. The program is tailored for convenience. For instance, you do not have to have a Bridge Inspection Certification until you are expected to inspect bridge construction.
Training is available for each of the certifications. However, you may choose to challenge an exam.

Options for inspector certifications are being researched and developed. Our primary goal is to craft a training plan and implement it by January 1, 2021. This will include a process for new and currently certified inspectors to obtain a 1-year certification. An additional goal is to create challenge exam events to extend certifications for the fully allotted time designated for each specific discipline. We will update the challenge events calendar after January 1, 2021.
