The revised One World Trade Center builds upon the original’s extraordinary level of life safety features and will include further features that will make it unprecedented in terms of life safety and security. In addition, the tower will provide a world-class model of energy efficiency and environmental sustainability.
The tower’s footprint at 200 feet by 200 feet, will be the same size as those of the original Twin Towers. As the tower rises from its cubic base, its square edges are chamfered back, transforming the square into eight tall isosceles triangles in elevation. At its middle, the tower forms a perfect octagon in plan and then culminates in an observation deck with a metal and glass parapet which reach a height of 1,362 feet and 1,368 feet respectively – the same heights of the original Twin Towers. The plan of the observation deck is a square, rotated 45 degrees from the base. A communications platform ring rises above the parapet and a 404-foot cable-stayed antenna for the Metropolitan Television Alliance (MTVA) rises to a final height of 1776'.
Rising from the plaza level, a 50-foot-high public lobby is topped by a series of mechanical floors; together these form the 186-foot-high building base, which will be reinforced for security reasons and draped with more than 2,000 sheets of prismatic glass. Sixty-nine office floors containing 2.6 million-square feet of office space rise above the base. There will also be world-class restaurants, below-grade shopping and access to the PATH and subway trains, as well as the World Financial Center.
The structure consists of a robust, high-strength concrete core paired with a highly redundant perimeter steel moment frame which together provide column-free interior spans for maximum flexibility of tenant use.
One World Trade Center will be seeking to achieve the gold standard under the Leadership in Energy and Environmental Design (LEED) by the US Green Building Council.
