Foundation and initial crane permits have been issued for O’Hare International Airport’s new Concourse D. Years in the making, the permit marks a major milestone for the structure, which began construction earlier this year. The effort is being led by the airport under the ORDNext project, which will eventually deliver a new Global Terminal and additional concourse.

Concourse D will be a remote concourse, meaning it will not be directly attached to the terminal building. However, it will sit just southwest of and connect to the existing Concourse C. The new 580,000-square-foot structure is being designed by a team composed of SOM, Ross Barney Architects, Arup, and JGMA.

Anchoring the concourse will be a central rotunda hall with a large oculus at the top. This space will connect down to a tunnel that will eventually link the concourse to the Global Terminal and a second remote concourse further west. The hall will also include 30,000 square feet of lounge space and ample concession areas surrounding a garden-like seating area.

The remainder of the concourse will be supported by tree-like columns representing the airport’s Orchard Field past. It will accommodate 19 new gates, 18 of which can be combined to serve nine wide-body aircraft. This flexibility will enable the creation of the nation’s first domestic–international codeshare concourse, according to official documents.

With these initial permits in hand, the airport can now advance from site preparation to full-scale construction, with vertical work expected to begin early next year. The $1.3 billion project is being built by a joint venture of multiple contractors, including AECOM, Hunt, Clayco, and Bowa Construction. The opening is currently scheduled for the end of 2028.

    Can we get some construction pics.

  2. State/Chicago politics will ruin this construction just like the state did on the cheap construction glass at the Thompson Center. The glass was always meant to be high quality though state says we no more money lets go with cheap glass. DA

    • For extreme weather conditions and soundproofing alone, this project is guaranteed to have some serious attention to detail. Tf are you going on about in this rant? Plus an addition of 40 years in glazing technology… Weird way to start the morning.

    • Another day, another delusional rant from westlooper!

  3. I see a people mover but I don’t see a monorail

    What is a “codeshare concourse”?

    • What Ai spat out. Not sure if this is describing a part of the whole or that’s the definition of itself.

      An airport concourse, or terminal, that handles flights with airline codeshares, which are flights where one airline sells a seat on a flight operated by another airline

    • Per AA Website:

      What’s a codeshare?

      Travel to more destinations
      Codeshares allow us to sell seats on flights operated by other airlines. This means you can easily combine American and flights with other partner airlines to create a single itinerary to multiple destinations.

      Our codeshare agreements make booking, checking in, checking your bags and traveling more convenient. Plus, the coordinated schedules make sure you’ll have enough time for all your connections.

      Tips for traveling on codeshare flights
      -Check in with the airline operating your first flight
      -Baggage policies differ between airlines and other charges may apply; check with the airline operating your flight for baggage information

    • Here’s the example I use:
      Lufthansa and United are codeshare partners. As the airport is now, if I’m flying Lufthansa from Frankfurt to LAX through Chicago, I’d land at ORD, go thru customs at Terminal 5, then take the train to Terminal 1 to catch my United flight to LAX.

      With a domestic-international codeshare concourse, I don’t have to change terminals. I land at the codeshare concourse, go through customs, then go right to my gate for the LAX flight because I’m flying on codeshare partners.
      At least I *think* that’s the gist of it.

      • I’m sure that’s right. Schiphol Airport in Amsterdam has this setup. You may have to clear customs/immigration between flights depending on the direction of travel but you don’t have to change terminals.

  5. I like the foliage!
