On 3 October 2008, the university celebrated the grand opening of the Experimental Media and Performing Arts Center (EMPAC) situated on the west edge of campus. The building was constructed on the precipice of the hill, with the main entrance on top. Upon entering, elevated walkways lead into a 1,200 seat concert hall. Most of the building is encased in a glass exoskeleton, with an atrium-like space between it and the "inner building". Adjacent to and underneath the main auditorium there is a 400-seat theater, offices, and two black-box studios with to ceilings. Originally budgeted for $50 million, the EMPAC construction costs ballooned to over $200 million due to difficulty of anchoring the foundation in the soft clay of the hill.
