The Detroit, Michigan Office
Leading the IEI Team in Detroit
“IEI’s Detroit oﬃce opened less than two years ago. In that short time, the ﬁrm has demonstrated its capacity for solving engineering challenges and its commitment to supporting the growth of Michigan’s vital infrastructure. IEI has been steadily growing its presence in Detroit and the surrounding communities by delivering infrastructure projects that align with the ﬁrm’s values and support local vibrancy. I am conﬁdent with this team that in a couple of years, we will look back and see that much has been done. We aim to be one of the leading ﬁrms in Michigan.” – Paul Ajegba
Paul leads IEI’s business development and operations for the Detroit, Michigan oﬃce, which is supported by 150+ engineers and administrative staff throughout IEI’s six oﬃces in the ﬁve states of Illinois, Indiana, New York, and New Jersey. He is a former Director of Michigan Department of Transportation (MDOT) with more than 32 years of experience in public infrastructure.
