Get to know the offices driving impact in major cities.
For over four decades, our Chicagoland team – Terracon Chicago, Glendale Heights, and Lombard – has explored alongside clients to help bring big ideas to reality across a wide range of sectors, including power generation and transmission, healthcare, industrial and logistics, commercial, digital infrastructure, transportation, federal, and oil and natural gas markets. With more than 100 professionals across our three Chicago-area offices, we offer trusted local expertise supported by historical data, deep regional knowledge, and practical insights.
We’re dedicated to helping you see opportunities clearly and avoid problems before they start. From early site selection through construction and long-term asset management, our team partners with you at every step of the project lifecycle. We stand apart in our industry through the depth of our expertise in complex Brownfields redevelopments, advanced deep foundation testing capabilities – including pile driving analysis and drilled shaft instrumentation – and our commitment to natural and cultural monitoring during construction. Our team is a trusted leader in the IEPA Voluntary Cleanup Program, guiding sites from assessment through closure. These specialized strengths help our Chicagoland team deliver unique value to our clients.
With a strong focus on responsiveness and collaboration, we leverage both local strengths and nationwide resources – including access to subject matter experts – to streamline decision-making for our clients.
We’re proud to have helped bring safety, quality, and resiliency to projects throughout Illinois like the Jane Byrne interchange, the Green Era Anaerobic Digester Campus — a 2026 Environmental Business Journal Project Merit Award winner, multiple data centers, and numerous solar farms.
Terracon’s Chicagoland offices have built strong local relationships and a well-established market presence. Our culture is rooted in community and connection – both inside and outside the office.
We host an annual Client Field Day, recurring client appreciation events, and actively engage with colleges and universities, speaking with engineering students to support academic programs and the next generation of engineers.
Our team stays active at regional conferences, professional organizations, and industry events. That same commitment to building strong relationships extends beyond our business and into the communities we serve, giving back through programs such as our annual Toys for Tots drive and support for local universities, including a foundation grant for the University of Illinois.
