CHOP's recent really big expansion. Construction not yet completed on all floors, but what does exist is state of the art and impressive. Constructed by Turner construction. Apparently a $450 million construction job. They have received so far ~$100 million in donations, including $50 million from the Buerger Family (hence the name).
A fantastic building and given CHOP a great medical center. Definitely worth stopping by just to see the walkway in the lobby - a one of a kind spiraling lobby ramp - known as the Leonard B. Kahn Walkway ($2 million).
Also of interest - they dug 70 ft down to make way for a 1,500-car parking garage (one of the largest excavations of its kind in the city). Also found this additional information from another website - "During the nine-month excavation, crews hauled out roughly 300,000 cubic yards of rock. Most of the rock went to the Philadelphia International Airport and was crushed for use on a runway project."
and finally, here's some additional information from the website:
The facility consists of a 700,000-square-foot building and five stories of parking below, with the ability to add an additional 175,000 square feet in the future. The building was designed with input from hundreds of families and clinicians.
