From one small office in Chicago to 10 offices across the country, IEI has grown through the dedication of our people and the relationships we’ve built along the way.
Today, we celebrate delivering infrastructure
projects that support everyday life, improve mobility, and spur economic development. These solutions are shaped by professionals who understand the communities they serve and the connections people and businesses rely on. As we have grown, connecting communities has remained at the heart of our work.
At the heart of IEI’s success are our employees, whose talent, dedication, and commitment to excellence have been instrumental in our growth and the reputation we have built over the past 28 years. We are also grateful to our clients and partners, whose trust, collaboration, and shared commitment to delivering meaningful infrastructure solutions have been essential to our success.
Together, we’re building on nearly three decades of progress to deliver what communities need next.
