The nation’s oldest teaching hospital unveiled plans for a building that aims to keep pace with “the next hundred years of advances in patient care,” as University of Pennsylvania Health System CEO Ralph Muller put it in a May announcement. The Pavilion, a 17-story facility on the former site of Penn Tower, will house inpatient care for the Abramson Cancer Center, heart and vascular medicine and surgery, neurology and neurosurgery, and a new emergency department. The design is by healthcare design firm HDR, architect Foster+Partners, and engineering firm BR+A. The $1.5 billion Pavilion, the largest capital project in Penn’s history, is expected to be completed in 2021.
