CHICAGO — Zach Baughman, a lawyer serving with the Chicago Department of Aviation, is overseeing the multi-billion-dollar infrastructure overhaul at O’Hare International Airport. The $8.8 billion modernization program represents one of the largest public aviation construction initiatives currently underway in the United States.

Despite lacking a traditional background in civil engineering or construction management, Baughman was selected to direct the massive capital improvement project. Program officials report that his legal background plays a central role in managing the complex procurement contracts, regulatory requirements, and inter-agency agreements essential to the development.

To navigate the technical demands of airport construction, Baughman utilizes an inquiry-focused oversight approach. Department representatives state that Baughman maintains direct engagement with engineering firms and lead contractors, systematically questioning operational details and technical specifications to monitor progress across all building phases.

The $8.8 billion capital plan includes significant enhancements to O'Hare's passenger terminals, the addition of new global gates, and extensive infrastructure upgrades across the airfield. The multi-year project is designed to expand operational capacity and modernize facilities at one of the nation's busiest transit hubs.

Construction activities remain ongoing as airport authorities work with airline partners and contracted build teams to maintain project milestones and uphold fiscal oversight throughout the multi-phase program.
