Excavation At 740 Eighth Avenue Progresses Further Below Street Level In Midtown, Manhattan
Quote:
Excavation is progressing at 740 Eighth Avenue, the site of a 52-story supertall hotel and observation tower in Midtown, Manhattan. Designed by ODA with SLCE Architects as the architect of record and developed by Extell, the 1,067-foot-tall skyscraper will yield 776,000 square feet with 825 hotel rooms in its lower half and a public observatory with a drop ride attraction above. The unconventionally-shaped structure will also contain retail space, two upper restaurant floors, and a pool deck for guests. Lendlease is the general contractor, WSP is the structural engineer, and Ancora Engineering is handling excavation and foundations for the property, which is located on an expansive lot along Eighth Avenue between West 45th and 46th Streets on the border of Times Square and Hell’s Kitchen.
A significant amount of dirt has been unearthed from the eastern half of the site since our last update in December, with excavators working well below street level. Crews have exposed large stretches of the foundation walls of the adjacent structures, as well as bedrock that is being secured with reinforced tie-back anchors in a staggered pattern across the southern perimeter. A framework of wooden boards and columns temporarily braces the northern and southern edges of the site until the foundation walls are formed. Additional excavation remains to be completed on the western end and at the corner of West 45th Street, where three low-rise structures will be preserved within the new building’s footprint. Based on the pace of progress, excavation should wrap up near the end of spring followed by the formation of foundations throughout the summer.
An official rendering has yet to be released apart from the axiomatic diagram posted on site. This drawing depicts a radically unconventional design featuring a stem-like protrusion capped with a slanted crown. The tower rises uniformly up to its midpoint, where a setback then gives way to a slender column that gradually widens as it approaches the pinnacle. The lower half appears to feature a more typical curtain wall while the upper half is shown clad in a distinctive corrugated façade.
The hotel and retail components will be housed in the lower floors, with the restaurant, observatory, and drop ride occupying the upper section. The top level of the observatory is planned to include an exclusive VIP space. The Intamin-designed drop ride will consist of three enclosed 260-foot tracks within the northern, southern, and western sides of the building’s stem. Each ride vehicle will carry up to four passengers on multiple lifts and free fall drops over a 90-second experience. The eastern face will likely house the elevators, egress staircases, and infrastructure for the observatory, dining, and VIP space above.
An anticipated completion date for 740 Eighth Avenue is posted on site for the second quarter of 2027.
