Construction update: One World Trade Center topped out!


On May 10th, 2013 (that’s few days ago), the One World Trade Center officially topped out to its final height of 541 metres or 1776 feet. The figure (1776) is in reference to the year of American independence, hence making the height of the this iconic tower very symbolic to the nation. Construction started in 2006 after all the clearing works had been completed on the site where the 911 tragedy struck that brought down the twin towers of the World Trade Center in 2001.

One World Trade Center, or famously known as Freedom Tower, is designed by David Childs from Skidmore, Owings and Merrill. It is to contain 104 floors of office space with a three-storey observation deck occupying the top portion of the tower alongside with mechanical levels which will goes up to 110th floor,  in another symbolic reference to the 110 stories of the original Twin Towers. Its roof stood at a height of 417 metres, which resembles the roof height of the former Twin Towers too.

The building has a square foot base, nearly identical to the footprint of the original Twin Towers, and from the 20th floor upwards, the square edges of the tower’s cubic base are chamfered back, transforming the building’s shape into eight tall isosceles triangles, or an elongated square antiprism. Near its middle, the tower forms a perfect octagon in-plan, and then culminates in a glass parapet whose shape is a square oriented 45 degrees from the base. A 408-foot (124 m) sculpted mast containing the broadcasting antenna – designed in a collaboration with lighting designers and engineers – is secured by a system of cables, and rises from a circular support ring. At night, an intense beam of light will be projected above the spire into the sky above.

Like I said before, on 10th May 2013, the final component of the spire was installed atop the skyscraper, making 1WTC the tallest building in the Western Hemisphere and the third tallest building in the world by pinnacle height. Now, let’s take a look at the current progress of the building’s construction from these very recently taken images from the others. The building is now at its final stage of construction, and is expected to be completed before end of this year.

The elevation of the tower looks very similar to Shanghai World Financial Center as you can see from the last image above. Previously, there was a change in the design of the tower at its base and on its spire even when it is already under construction at the time of the revision. But the part that affects my impression to the tower is its spire’s design now. Previously, there should be a glass radome below the spire which gently acts as a beautiful transition from the massive building block to the thin and slim pinnacle above. Now, that is omitted, and it leaves the building in quite an awkward feeling. The fully glass-clad building that ends ‘suddenly’ with a long spire. Ehh…Luckily, the circular ring at the roof is still there. I’m looking forward to the lighting design to the tower. Hmm…this building looks massive to me, but not that impressive. Anyway, it’s a very clean, bold and symbolic tower to United States. Now, it towers above all of its neighbouring buildings in Lower Manhattan, New York City.

  1. Hey! Quick question that’s entirely off topic. Do you know how to make your site mobile friendly? My weblog looks weird when browsing from my apple iphone. I’m trying to find a template or
