QUALIFIED PRODUCT POLICY 24

A request to qualify a manufacturer along with samples and certifications should be submitted to:

Caleb Gunter, PE

Structural Steel Engineer SCDOT Office of Materials and Research

1406 Shop Road Columbia, SC 29201

(803) 737-6694 Fax: (803) 737-6649

Email: guntercb@scdot.org

When the Office of Materials and Research is satisfied with the manufacturer's performance in fabrication and testing, the manufacturer will be added to QPL 24 and will be authorized to conduct the tests and certify the results.

3.0 After Initial Qualification:

After initial qualification of a manufacturer, further samples will not be necessary for additional projects awarded at a later date. However, the Department reserves the right to sample and test bearings at any time or to require repeat prequalification.

A certification is required with each shipment of elastomeric bearings. This certification must demonstrate (with test results from a bearing produced with this shipment) that the bearings meet the Durometer Hardness requirements shown on the Plans and the requirements of Section 2.2 of this specification.

The Department reserves the right to perform inspections or to send consultant agencies to perform inspections at the producer’s facility during production of bearings for SCDOT projects.

After qualification, the Structural Steel Engineer must be notified immediately of any elastomer formula changes and the requirements outlined in Section 2.2 and 2.3 of this specification must be submitted for the new formulation.
