One World Trade Center will not be the tallest building in the Western Hemisphere – at least not today.
The scheduled Monday morning delivery of the final two sections of the building’s 408-foot, 800-ton spire was cancelled due to heavy winds.
The two stainless steel sections, comprising the 17th and 18th pieces of the spire, will bring the building to 1,776 feet, at which point it will supercede Chicago’s Willis Tower as the tallest building in the Western Hemisphere.
The first piece of the spire, installed in January, weighed more than 67 tons, and the additional two pieces will add another six tons.
The spire is a joint venture between Canadian engineering firm ADF Group Inc. and New York-based steel contractor DCM Erectors Inc.
The world’s tallest building, topping 2,700 feet, is the Burj Khalifa in Dubai.
The Port Authority of New York and New Jersey did not immediately return calls seeking comment on rescheduling efforts.
