Latham PlaceIn 2013, The Setai Fifth Avenue Hotel and Residences was re-branded as “Langham Place, Fifth Avenue,” as part of Langham Hotels International Limited, based in Hong Kong. The project site is at 400 Fifth Avenue between 36th and 37th Streets, just steps away from the Empire State Building. This development involved the construction of a new, 567,000sf, 57-story (two levels below grade plus mechanical penthouse) mixed-use building with 372,000sf of residential space, and 195,000sf for the Setai Hotel. The hotel space includes restaurants, bars, a spa and a fitness and movement studio.

The sleek façade of the 700ft tower is a combination of precast concrete and limestone with stainless steel elements and a stainless steel crown at the top of the structure, which splays expansively outward at the 58th-60th floors. The tower, set back from the street, respects its neighboring buildings with the use of horizontally faceted window profiles established within the podium. Viewing the structure from a distance, the building appears to be a glass-enclosed tower, while approaching at street-level; the Setai is an amazing pre-cast concrete structure with windows separating the pre-cast exterior columns along the façade. The Setai’s window system features a particularly unique design aspect. The windows are faceted—or angulated—and the outside corners at the condominium levels are all glass, giving residents a stunning view of Midtown Manhattan, as well as the Hudson and East Rivers.

Two large stainless steel canopies flank the building’s hotel and residential entrances, forming terraces for some of the hotel rooms on the fifth floor. The 11th floor, allotted for amenities, includes spacious terraces, as well as cozy outdoor fireplaces.The Setai’s interior features very high-end finishes for both the hotel and condominium apartments. Every room has extensive millwork, glass and ornamental metals.

Maintaining a labor intensive project such as the Setai without compromising on the sumptuous materials all the while keeping the project under budget was a challenge. One particular challenge concerned the overseas manufacturer of stone and millwork finishes, which presented unique issues with coordination and materials. In order to maintain the desired design and interior spaces in the hotel and condominiums, the project team worked closely with the building’s ownership and design consultants, to expedite alternate solutions. Ultimately, we provided first-class materials within the project scheduling parameters.

Site safety is of utmost importance for any Structure Tone project. Because of the size and scale of the Setai, we implemented a unique cocooning system that completely enclosed the perimeter of the floors under active construction, this provided perimeter protection of workers, and allowed for stripping operations to proceed safely. This also served as a “catch-all” system for construction debris, thereby protecting the public and surrounding areas from falling construction material. The cocoon system was independent of the formwork system for the structural concrete construction operation, and “slid” up with the active floors as construction progressed vertically. The system had no negative impact to the project schedule.

The aggressive schedule for the Setai’s concrete pour cycle was two and a half floors per week. DOKA supplied the formwork protection and safety system used during this superstructure phase to ensure safety while maintaining the lofty schedule requirements. The project used 22 Xclimb 60 protection screens and five loading platforms. The room high enclosures provided complete protection around the perimeter edges of the floor slabs where edge falsework and column-forming operations were performed. The protective screen sheeting was available in a perforated sheet for warm weather conditions and as a solid sheet for colder climates. The five Xclimb 60 loading platforms were used at the site to transport materials from one level to the next. These loading platforms, which climb on the building’s exterior, allowed for easy cycling of slab formwork, and safe climbing, even in bad weather.

For a project of this size and scale we also set up a medical trailer on-site to use as a safety orientation space for tradesmen. This also allowed for minor medical treatment in a timely manner if the need arose.

The building’s footprint is 16,700sf, and juts out over the property line of both 36th Street and Fifth Avenue, and to the north of the project site is an eight-story landmark building, with other adjacent properties to the west. During the preconstruction phase, we devised a plan that involved routing pedestrians off Fifth Avenue and then through the building in a safe manner and back out. This enabled us to close the sidewalk on Fifth Avenue to use that area as lay down space. We also used the 11th floor setback and terrace for staging, as well.
