O'Hare International Airport Transit System Expansion and Modernization

The City of Chicago awarded a contract to Parsons Construction Group, Inc. to modernize and expand the existing Airport Transit System (ATS) at O’Hare International Airport (ORD). As part of the Parsons Team, JWI is providing quality management, safety coordination, and CADD services.


The $310 million contract calls for Parsons to construct a 2,000-ft track extension (superstructure designed/constructed by others) to reach the new Joint Use Facility (JUF) and for the design and replacement of the existing ATS system that currently operates between the existing terminals and remote parking lot E. This contract is part of the Chicago Department of Aviation (CDA) initiative to consolidate all of the rental car companies into one JUF, as well as offer new public garage parking for airport passengers.  Under the contract, the ATS maintenance and storage facility will also be expanded, and the existing 15-car ATS fleet will be replaced with 12 sets of triplet vehicles totaling 36 new cars that feature automated vehicle control, traction power and communications improvements. The primary objective of the ORD Airport Transit System Expansion and Modernization project is to improve ground transportation and air quality at the airport.
