^Not sure the exact floor - but seems to be a very complex design:
"“It has been a bit like making a 51-story Swiss watch,” explained Partner and Design Principal in Charge, David Ertz, AIA, LEED AP. “Our familiarity with the site, how various elements can be vertically arranged, and the different hotel flag requirements are complemented by our continued emphasis on maintaining a high level of architectural design throughout the process.”
Due to the complex program requirements of two hotels, nearly every floor in the tower is customized, with the structural grid changing to accommodate interior plans. Through extensive teamwork and collaboration with the client and hotel operator, the design team identified solutions that will create a unique guest experience.'"
