The Waldorf Astoria Hotel is a luxury hotel on Park Avenue in Manhattan. The 47-story, 625 foot tall Art Deco landmark, designed by architects Schultze and Weaver, dates from 1931. Bowman utilized GPS survey methods to establish geodetic control on the main rooftop and at ground level. With control established, Bowman performed 3D laser scanning operations to capture the existing conditions and improvements on the main rooftops and two existing towers. At ground level, Bowman scanned the restaurant, flagpole bracing, and surrounding area. In 2011, Bowman was contracted to complete 3D laser scanning operations on the full exterior of the Waldorf Astoria. In order to accomplish the exterior scan, crews occupied six adjacent building rooftops, and performed 3D scanning at street level. Collaborating with our client, we provided detailed deformation studies on over twenty areas of interest on the exterior façade. In 2016 plans were announced to covert 1,100 rooms into luxury condos. Bowman performed 3D laser scanning on four floors to observe the visible existing conditions over approximately 150,000 square feet of the building’s interior and exterior. Bowman also conducted post-demolition surveys and floor level analysis of the interior floors 12, 24, 43 and 44, as well as the building stairwells from floor 1 through 42. Additionally, Bowman provided a sidewalk survey prepared in accordance with the New York City Department of Transportation.
