The 925-foot building has a slenderness ratio of 1:10.5. There are several floor set-backs at different locations up the height of the building. The structure is a reinforced cast-in-place concrete construction. The building is supported on columns and shear walls formed around the elevator shafts, staircases and along a few divider partitions between the hotel and residential units. At the upper floors the shear walls are formed around the elevator shafts and staircases only.

Column transfers were required to accommodate the architectural layouts and building set-backs. Some transfers were achieved by using a thicker slab and some were achieved by using “walking columns”, which means introducing one-to-three-story “walls” that transfer the load from one location above to a different location below. The “walking column” system is less intrusive and less expensive than the conventional pick-up girder system.

At the mechanical floor on the 24th story, a belt wall was created, engaging all the perimeter columns to the central core via outrigger walls (two in each direction, for a total of eight outrigger walls) to stabilize and stiffen up the building. The hotel floor slabs are flat plate eight inches thick supported by columns (interior and exterior) and core walls. The typical residential floor slabs are nine inches thick supported by exterior columns and core walls, giving architectural freedom to change the layouts without any structure interruptions.
