The original structure of 360 State Street consisted of a cast-in-place structural system throughout the entire residential tower. Due to local trades being unable to provide a competitive cost and schedule, the design was later changed to staggered steel trusses. It was assumed that the engineers were not able to fully investigate alternative design solutions in order to meet the deadline for complete construction documents. The intent of this report therefore; is to verify the existing design by comparing it to an alternative.

The structural depth study investigates a more traditional steel frame thatpotentially could provide a more competitive cost and schedule.The breadth topics of the report include a building envelop study which proposes an all-glass façade and a cost & schedule comparison of the existing and proposed systems.
