This 20-story, 195 key hotel is comprised of a post-tensioned two-way slab system and concrete core walls. The exterior envelope is comprised glass curtain wall and precast concrete.
Due to the tight site logistics, FSE developed a cantilevered mat slab solution supported by deep caissons. The mat thickness varies from 36 inches to 60 inches in order to accommodate perimeter conditions without impinging on the existing adjacent construction and property line constraints
During construction, FSE worked carefully with the general contractor and concrete subcontractor to achieve a 3-day floor-to-floor cycle.
