28Quality Assurance Laboratories perform Independent Assurance (IA) and/or Verification tests
during production of materials. These laboratories perform a portion of the tests that the Quality
Control Laboratories perform.
The quality control and quality assurance test results are
compared to each other to determine the reliability of the quality control testing program.
The ODOT Central Laboratory will certify all Quality Assurance Laboratories for those test
methods necessary to perform quality assurance tests of construction materials for ODOT
construction projects. This certification will be valid for one year. If a laboratory’s certification
expires and the laboratory has a continued need to test materials for ODOT construction projects,
the laboratory shall apply for re-certification. An outline of the on-site inspection process and
laboratory certification criteria is found in Appendix A.
This laboratory certification process is designed to provide not only a “snapshot” of the quality
of a laboratory, but also an evaluation of the laboratory’s performance in maintaining quality and
consistency.
ODOT Central Laboratory inspectors will examine the laboratory’s testing
equipment for accuracy and conformance to specification. In addition, the quality assurance
laboratory is required to participate in the ODOT Central Materials Laboratory Proficiency
Sample Program (see Appendix B). If the laboratory’s equipment is properly calibrated and
within specifications, and if the laboratory meets all other conditions specified in Appendix A,
then ODOT will certify the laboratory as competent and able to perform independent assurance
and/or verification tests of materials for ODOT construction projects.

Dispute Resolution Laboratories
When Quality Control and Quality Assurance test results conflict and the conflict cannot be
resolved; a neutral Dispute Resolution Laboratory will test the material in question. The test
results of the Dispute Resolution Laboratory will decide the dispute.
The ODOT Central Laboratory will perform all third party and dispute resolutions unless
a potential for conflict of interest exists.
In the event that the ODOT Central Laboratory acts as the Quality Assurance laboratory, and that
the dispute is therefore between the Quality Control Laboratory and ODOT Central Laboratory,
the ODOT Central Laboratory will defer its dispute resolution duties to a certified laboratory
agreed upon between ODOT and the Contractor.
The ODOT Central Laboratory shall certify dispute Resolution Laboratories., other than the
ODOT Central Laboratory.
Any Laboratory which has run Independent Assurance, Verification or Quality Control testing
on the material under dispute is considered to have a conflict of interest and shall not perform
Dispute Resolution on its own tests.
