The City of Chicago has selected Studio ORD to lead a team of architects selected to design the $2.2bn global terminal of O’Hare International Airport, which is part of an $8.7bn expansion project.

After a competitive process, the City of Chicago shortlisted five qualified architect teams, with Studio ORD emerging as the winning team.

Studio ORD is a joint venture (JV) formed by Corgan Associates, Milhouse Engineering and Construction, STL Architects, Solomon Cordwell Buenz & Associates, and Studio Gang Architects.

Chicago will now enter into contract negotiations with Studio ORD. Once the contract is finalised, Studio ORD will collaborate with the City of Chicago and the airlines to design the new Global Terminal and Concourse.

“During this historic competition, the world’s best architecture firms submitted their incredible visions for the world to see.”

A second team will also be chosen from the remaining four finalists to design two new satellite concourses which will be constructed west of Terminal 1.

Chicago Mayor Rahm Emanuel said: “The City of Chicago called upon teams from across the city and around the world to lead O’Hare’s historic expansion, and Studio ORD answered that call.

“During this historic competition, the world’s best architecture firms submitted their incredible visions for the world to see, with each of these five world-class designs strengthening our plans to bring O’Hare into the 21st century.”

O’Hare’s new international terminal is expected to span across 2,250,000ft² and will be among the largest terminals in the US. It will cater to the needs of 83 million passengers annually.

Once commissioned, the new facility is expected to more than double the space at exisiting Terminal 2, replacing it with an expanded arrivals hall.

The new terminal will feature additional gates, more space for concessions, lounges and public amenities, new baggage systems, and advanced new technologies to improve security screening.

The O’Hare Global Terminal will entail an investment of $2.2bn and its construction is scheduled to commence in 2023.
