Quality Reviews

AEI has provided quality assurance reviews of the stage construction and maintaining traffic plans prepared by others to ensure completeness and accuracy, and to check for conformity with MDOT/industry standards and practices. During our reviews, we draw from our experience on similar past projects to identify potential issues and recommend remedial measures.

  • I-75 Modernization Project (Segments 1, 2 & 3) in Oakland County, Michigan
