Wills Eye Hospital

Location: Philadelphia, PA
Architect: Heery

O'Donnell & Naccarato provided structural engineering services for Wills Eye Hospital's Walnut Tower Vertical Expansion in Philadelphia, PA. The new 8-story, 130,000 SF steel-frame medical office building and ambulatory surgical center was constructed atop an existing seven-level, cast-in-place concrete parking structure. The elevator core was hung at the exterior for the full height of the new and existing structure from a cantilevered steel plate girder. The design also included a 60-foot tall spire featured at the top of the tower.
