Quality Assurance

The purpose of the Oregon Department of Transportation’s Quality Assurance program is to insure quality materials and workmanship are used in the construction of all transportation projects administered by ODOT or its consultants. 
ODOT’s QA Program consists of three separate and distinct sub-programs as illustrated below. 
Quality assurance program has three sub groups: quality control, verification, and independent assurance  


All personnel who perform and report on tests required on ODOT projects must be certified. For information about what the certifications are, how to get certified, and who is currently certified, please visit our Technician Certification Program page.

Regional Support

The regional Quality Assurance staff is responsible for verification testing and Independent Assurance Testing on all ODOT projects. They are also the primary resource for questions about materials testing and administration of ODOT’s QA Program on construction projects.
