What Infrastructure Engineering, Inc. does
Infrastructure Engineering, Inc. (IEI) is a privately held, majority African American-owned civil engineering firm founded in Chicago in 1997 by Michael Sutton, PE. The firm delivers three integrated core services: Design Engineering (transportation, bridges/structural, site/civil, and water management design), Construction Engineering and Inspection (resident engineering, value engineering, schedule and budget controls, and quality assurance), and Program Management (multi-stakeholder program coordination, commissioning, cost estimating, and document control). IEI executes these services under its proprietary INGENUITY engineering process, working as both prime consultant and sub-consultant across multi-phase (Phase I/II/III) engagements.
The firm serves primarily federal, state, and local public-sector clients, with a customer base spanning departments of transportation, tollway and transit authorities, airport authorities, water management agencies, school systems, and economic development corporations across Illinois, Indiana, Michigan, New York, New Jersey, Texas, Georgia, and California. Notable engagements include the George Washington Bridge Priority Repairs (PANYNJ), the LIRR Expansion Project (MTA, part of a $5B program), Reagan Memorial Tollway I-88 (Illinois Tollway, $43M construction budget), C*NECT Citywide Program Management (CDOT), and the Hannah Street and Throgs Neck pumping stations (NYCDEP). The firm also serves private owners of all sizes on complex site/civil development projects.
IEI operates on a professional-services revenue model with project-specific, quote-based pricing and no publicly disclosed rates. The go-to-market is sales-led direct engagement with public agencies and private clients, augmented by strategic teaming partnerships and joint ventures, and supported by relationship-based marketing, industry-event participation, an internship pipeline, and the affiliated Infrastructure Engineering Foundation. As of 2026, the firm employs 200+ professionals across 10 offices in 8 states, reported roughly $300M in cumulative construction-cost oversight for the Indianapolis market since 2006, and was ranked #17 on Crain's 2025 List of Largest Engineering Firms and named an ENR 2026 Top Midwest Design Firm.
