MDOT is Updating Prequalified Aggregate Supplier List – Industry Action Required!!!


MDOT is currently in the process of digitizing their prequalified aggregate files and creating a more streamlined approval process.   During this update, they have noticed several discrepancies between various files (i.e. region office, Lansing office, etc).  Due to these differences, MDOT will be performing a comprehensive information/document review.

Therefore, suppliers that are currently listed as a MDOT Prequalified Aggregate Supplier List should be receiving a form to fill out for each of their sources.

This form will be sent via email from the MDOT Region contact stating the following:
