This project consisted of adding a 12,000 square foot third story to an existing, fully occupied two story structural steel framed, brick and glass veneered Student Union building on the University of Oklahoma Health Sciences Center Campus. Once dried in, many lavish finishes were added including vaulted ceil ings, mahogany wainscoting and crown molding, built -in library shelving, and an open terrazzo stair with glass side rails.  The finished area houses the Bursar’s Office, a conference room, six executive offices, and several open lounge areas. The project was completed with students and faculty entering and exiting the building hourly through numerous entrances without any incidents.
