Over the course of the current semester, the structural depth explored changes to both the gravity and lateral system. The gravity system was changed from composite steel framing to voided flat plate concrete slab supported by reinforced concrete columns, while the lateral system was reduced to a simpler version that contains only reinforced concrete shear walls. The original design strived for world class acoustics, including double-walled construction to block sound from a nearby train. Due to budget constraints, double-walled construction could not be used on the auditorium hall’s roof as intended and a 6.5” concrete topping on 3VLI deck was used instead. The goal of the acoustic breadth was to determine if the changes made to the structure of the auditorium roof are more effective at blocking external sound than the current roof system and what additional changes, if any, can be made to further sound-proof the roof to a level expected by the owner. Rough costs analyses done through the construction management breadth aimed to determine whether the changes made to the structural system could justify the use more effective, and possibly costlier, means of sound-proofing the main auditorium’s roof.
