Materials Lab - Qualified Products List (QPL)

Do not submit application and money prior to contacting the QPL Engineer.

The proprietary Wall Design Review process is temporarily closed to new applications.

The Qualified Products List is compiled by Washington State Department of Transportation's (WSDOT) Materials Laboratory.

Search the QPL by selecting a manufacturer or a standard specification

The QPL is a database of over 1,400 construction materials that have been pre-approved for use in WSDOT highway construction. Where there is a conflict between the QPL and the contract provisions, the contract provisions shall take precedence over the QPL. WSDOT is not responsible for errors or omissions in the QPL.

In accordance with WSDOT Standard Specifications for Road, Bridge and Municipal Construction Section 1-06.1(1), this website is considered to be the current QPL.

Products that do not perform or found to be noncompliant with WSDOT specifications may be removed at any time from the QPL. These products will not be re-entered into the QPL or approved for use in the State of Washington until such time that adherence to the specifications can be verified and the products have undergone satisfactory performance evaluation.
 
QPL Submittals - Materials  

As of July 1, 2021, QPL applicants will be required to enter into a Reimbursable Agreement with WSDOT for evaluation services with the Materials Laboratory. See the QPL flow chart (pdf 185 kb) for details on the agreement and the evaluation process following the signed agreement being received from the source representative.

Charges will be billed after the work has been performed, and the source will be invoiced monthly for services performed. Monthly invoices can be paid electronically through the Materials Evaluation Program (MEP).

QPL applicants (Referred to as Vendors in the Flow Chart referenced above) will be required to register with the Washington State Office of Financial Management with a Vendor/Payee Registration Form. Vendors are free to fill out the form at any time, before or during the QPL process. Send the completed PDF form to PayeeRegistration@ofm.wa.gov. and CC Kristy Vargas at the WSDOT Lab Business office at Kristy.Vargas@wsdot.wa.gov .

The form can be found at Statewide Vendor/Payee Services | Office of Financial Management (wa.gov).

Once this process is initiated, an initial evaluation package will be sent to the applicant. This package will include a budget sheet that shows the estimated costs  necessary to cover the evaluation. Payment can be made either by check or electronically through the Materials Evaluation Program (MEP) when the monthly invoices are received.
