Chicago O’Hare International Airport (ORD) Airport Transit System (ATS) Expansion and Modernization


Part of a Chicago Department of Aviation (CDA) initiative to consolidate all rental car companies serving ORD into a single Joint Use Facility (JUF) and offer new public garage parking for airport passengers, this design-build project called for the expansion and modernization of the existing Airport Transit System (ATS) at O’Hare International Airport. Scopes included a 2,000-ft track extension bringing service to the new Consolidated Car Rental and Parking Structure (CONRAC), expansion of the ATS maintenance and storage facility, and replacement of the existing 15-car fleet with 12-sets of triplet automated control vehicles. The current track was replaced, and the ATS system was re-designed entirely, including extensive train control, traction power, & signal improvements. As part of the design-build team, JWI oversaw and participated in developing design elements, performed constructability reviews, managed QA/QC processes & procedures, monitored electrical & system testing, and provided safety oversight, CADD, and scheduling services.
