Built to house research and administration staff, the Roberts Center for Pediatric Research was the first of four towers for the Children Hospital of Philadelphia (CHOP) built on an 8-acre site along the Schuylkill River. The 21-story, curved glass facility posed a unique challenge due to the steep grade change which necessitated a three-story elevated plinth structure which also includes parking.
- We evaluated multiple structural systems for both the tower and plinth during the early design stages. A structural concrete core with steel-framed floors was selected as the primary structural system.
- Close communication with the steel fabricator during the submittal process resulted in expedited turnarounds with minimal resubmissions. This enabled steel erection to proceed quickly right behind the concrete core construction.
- The plinth’s design used galvanized steel framing with a reinforced-concrete slab on non-composite steel deck to better withstand the exposure to vehicular traffic in the parking garage.
