a number of architectural organizations still practice there, including the Goettsch Partners, VOA Associates, Harding Partners, and the Chicago offices of Skidmore, Owings & Merrill and landscape architecture and planning firm, Design Workshop. The building was purchased by the University of Notre Dame in 2006. The university's Mendoza College of Business began holding classes there in 2008. From 2009 to 2018, visitors enjoyed the 320-square-foot Chicago Architecture Foundation scale model of central Chicago in the building's atrium. [An expanded model — with accompanying light show and interpretation — is now at 111 East Wacker Drive, where the CAF moved in 2018; CAF simultaneously changed its name to the Chicago Architecture Center or CAC. CAC continues to update the expanded city model to reflect architectural changes in the downtown area.] In 2011, Anacostia Rail Holdings moved its corporate headquarters to the Railway Exchange Building.
