The Council on Tall Buildings and Urban Habitat convened its Height Committee on November 8th in Chicago to evaluate its criteria for determining the official height of buildings, and to rule on the official height of One World Trade Center in New York.
The Height Committee has reached a consensus that One World Trade Center’s height to its architectural top is 1,776 feet (541.3 meters).
Note, because One World Trade Center is still unfinished and has not received its certificate of occupancy, it cannot yet enter CTBUH rankings as a “completed building,” but its height is no longer in dispute.
There were two central issues for discussion in the ratification of this building’s height against CTBUH criteria.
The nature of the mast structure on top of the tower.
The datum line (bottom point) from which the height to architectural top was determined.
This determination was made through examination of design and construction drawings, and continued through dialogue among the Height Committee’s 25 members. The committee received a 15-minute presentation by the One World Trade Center owner/design team, including the project’s chief architect, David Childs of Skidmore, Owings & Merrill LLC (SOM) and Ken Lewis, project director at SOM.
“We were very satisfied with the detailed information presented by the team, in particular, that which affirmed that the structure on top of the building is meant as a permanent architectural feature, not a piece of functional-technical equipment,” said Timothy Johnson, Chairman of CTBUH and Design Partner at NBBJ.
“The design of One World Trade Center, as explained to us, reinforces its role as a symbol of resurgence on this important site,” said CTBUH Executive Director Antony Wood. “In particular, the spire which holds the beacon light, shining out at the symbolic height of 1,776 feet, is especially poignant – echoing the similarly symbolic beacon atop the Statue of Liberty across the water.”
