University Hospital, a 608 bed facility with a Level 1 Trauma Center, was completed in 1989. Due to the age of the existing roof, a replacement roof was required. The replacement roof consists of a thermoplastic polyolefin (TPO) roof that was installed on all the upper roofs. All of the lower roofs with the exception of the area in front of the North Tower received the same roof system.

The design of the green roof, which consisted of vegetation and a growing medium planted over a waterproofing membrane, was installed on the lower roof above the hospital lobby.

The work began in late 2011 and was completed August 2012.
