1 Manhattan West is a 67-story office building in the Manhattan West development. It is scheduled for completion in 2019 and will serve as the second tower completed in the development after 3 Manhattan West.
The structural system of the tower is composed of a central reinforced concrete core and a perimeter steel moment frame. Part of the tower overhangs the below ground train tracks leading into Penn Station. In order to avoid the tracks, the perimeter columns on the south, north, and east sides do not come down to ground level, but are transferred to the core above the building's lobby.
