One World Trade Center Becomes the Tallest Building in New York [Video]

In honor of One World Trade Center becoming the tallest building in New York, EarthCam has released an exciting time-lapse movie showcasing the construction progress from 2004-2012. Watch years of construction in just two minutes!

Today One World Trade Center surpassed the Empire State Building to become the tallest building in New York City. This amazing two- minute time-lapse video shows construction from the foundation to where it is today at 1250 feet tall.

City officials and iron workers applauded as the first 12-tonne column was hoisted onto the tower’s top deck. “This project is much more than steel and concrete. It is a symbol of success for the nation,” said David Samson, chairman of the Port Authority, the agency that owns the World Trade Center.

Clear skies afforded an immaculate 360-degree view from the top, although it wasn’t easy getting up there. After riding an elevator to the 90th floor, a small group of officials and journalists had to climb three steep ladders to reach the top platform, which was encircled by blue netting along the perimeter.

However, the skyscraper, which was built to replace the twin towers destroyed in the September 11 attacks, is still unfinished with another few floors expected to be added over the next year.

Once completed, officials hope the high-rise will be the tallest building in America and the third tallest in the world.

Crowning the world’s tallest buildings is a little like picking the heavyweight champion in boxing. There is often disagreement about who deserves the belt.

In this case, the issue involves the 124-metre-tall needle that will sit on the tower’s roof.  The building, unofficially called the Freedom Tower, is considered by some a poignant symbol of America rising up against its enemies after the terror attacks on the site in 2001.

Count it, and the World Trade Center is back on top. Otherwise, it will have to settle for number two, after the Willis Tower in Chicago.

“Height is complicated,” said Nathaniel Hollister, a spokesman for The Council on Tall Buildings and Urban Habitats, a Chicago-based organisation considered an authority on such records.

Experts and architects have long disagreed about where to stop measuring super-tall buildings outfitted with masts, spires and antennas that extend far above the roof.

Consider the case of the Empire State Building: Measured from the sidewalk to the tip of its needle-like antenna, the granddaddy of all skyscrapers actually stands 443m high, well above the mark reached by One World Trade Center.

Purists, though, say antennas shouldn’t count when determining building height. An antenna, they say, is more like furniture than a piece of architecture. Like a chair sitting on a rooftop, an antenna can be attached or removed.

The Empire State Building didn’t even get its distinctive antenna until 1952. The record books, as the argument goes, shouldn’t change every time someone installs a new satellite dish.

Excluding the antenna brings the Empire State Building’s total height to 381m. That was still high enough to make the skyscraper the world’s tallest from 1931 until 1972.

From that height, the Empire State seems to tower over the second tallest completed building in New York, the Bank of America Tower.

Neither the Willis Tower nor One World Trade are as high as the CN Tower, in Toronto, which stands at 553 feet.

That structure, however, isn’t considered a building at all by most record-keepers, because it is predominantly a television broadcast antenna and observation platform with very little interior space.

The tallest manmade structure in the Western Hemisphere will continue to be the 629m-tall KVLY-TV antenna in Blanchard, N.D.

As for the world’s tallest building, the undisputed champion is the Burj Khalifa, in Dubai, which opened in 2010 and reaches 828m.

Not counting about 1.5m of aircraft lights and other equipment perched on top, of course.
