This 775,000 sf mixed-use tower sits on a trapezoidal site between Halsted and Green Streets, featuring landscaped steps to manage a 16-foot grade change, electric heat, and 19 elevators to support dense occupancy. Amenities include a sky deck, lounge, bar, dry cleaning, secure bike room, and shuttle service to Ogilvie and Union Stations.
Early Collaboration Allows Seamless Installation
The kinetic wall, including 98,000 individual metal "flappers,” surrounds the parking levels and allows air to flow naturally through the space. The flappers move with the wind, creating a pulsating design while also providing an interesting enclosure to mask the parking levels. It is the second such system to be installed in Illinois. Our quality support and project teams worked with the subcontractor and designer to understand the various components of the system and ensure that all elements would be installed correctly.
Freight Tunnel & Rail Coordination
A Chicago freight tunnel runs through the north side of the site. The team cantilevered caissons and constructed foundations directly over the existing tunnel without disruption. Metra tracks sit adjacent to the site, requiring close coordination with Metra officials to protect the project schedule and maintain uninterrupted rail operations.
