City of Chicago Facilities

For the Department of General Services, Paul supervised renovation and maintenance across City facilities, including public safety buildings and offices, and was responsible for adherence to safety, accessibility and construction codes. Public work in Chicago is closely documented, permitted and inspected, which gives him practical familiarity with the records and procedures that govern it.

O'Hare International Airport

At O'Hare, Paul oversees large-scale renovation, maintenance and construction across terminals, concourses and public facilities. He directs more than 25 skilled trades responsible for carpentry, flooring, plumbing, electrical and finish work; manages the installation of furniture and fixtures in public areas including restaurants, food courts and waiting areas; and coordinates work so that airport operations continue without interruption. Renovating one of the busiest airports in the country while it stays open requires constant attention to sequencing, protection and quality.
