Tallest Hotel in Western Hemisphere Tops Out

NEW YORK, NY—The 70-story, 371,000-sq.-ft. Marriott, located at 1717 Broadway at 54th Street, has topped out. The announcement was made by Ken Colao, president of CNY Builders, the project’s construction manager. The superstructure was topped out in 231 days, which entailed roughly pouring five floors every 10 days.

The $200-million project, developed by Granite Broadway Development LLC, is the tallest stand-alone hotel in the Western hemisphere. It is over 750 ft. in height and has a floor-to-area ratio of 30:1.

Two Marriott “select service” hotels will be housed within the structure and will become flagships for their brands: a 378-key Courtyard by Marriott on the lower floors and a 261-key extended-stay Residence Inn on the upper floors. Areas shared by the two hotels include public space and lobbies, a fitness club, lounges, a bar area and restaurants, a retail store, a business center, a conference center and outdoor terraces.

“This project is especially complex because it required some unusual approaches to construction,” Colao said in a statement. “Most significant of all has been the site’s extraordinary logistical challenges, with three major buildings being constructed simultaneously on one block. Our 70-story concrete building is sandwiched between and directly abuts a concrete high-rise hotel being built on our western property line, and a subway and Broadway on our eastern property line.”

The second complication, pointed out by Colao, is the building’s slender structure—more than 750 ft. on a footprint that is 10,000 sq. ft., and that then sets back to 6,500 sq. ft. on the sixth floor and to 4,800 sq. ft. on the 36th floor. Further complications resulted from the high-end glass curtainwall system on the slender high-rise concrete superstructure.

Project partners include Nobutaka Ashihara Associates (architects), Cantor Seinuk (structural engineer), Edwards & Zuck (engineer), Bill Rooney Studio Inc. (interior designer) and IBA Israel Berger Associates (facade consultants).
