Mackey Mitchell staff members are planning a visit to Gateway Steel Fabricators to see the progress of the incredible atrium steel being fabricated for the new Olin School of Business at Washington University in St. Louis.  The university launched a major expansion project that will nearly double the business school’s footprint on the Danforth Campus.The project includes two innovative buildings united by a soaring glass atrium. The business school complex was designed by Moore Ruble Yudell (Santa Monica, CA) with Mackey Mitchell as the local architect.
