World’s Tallest Tower – BURJ KHALIFA
Burj Khalifa formerly known as Burj Dubai prior to its inauguration, is a skyscraper in Dubai, United Arab Emirates, and the tallest man-made structure ever built, at 828 m (2,717 ft). Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010. A closely guarded secret, the official height of Burj Khalifa was flashed onto a giant screen before an estimated crowd of more than 400,000, as lasers and fireworks lit up the night sky. Fireworks cascaded from the tower’s spire to the base and lasers blazed out from all levels leaving the crowds awestruck. The height was disclosed in arithmetic progression, with the numbers being flashed onto the screen, one after another. The tower’s height breaks all existing world records for tall buildings. The building is part of the 2 km2 (490-acre) flagship development called Downtown Burj Khalifa at the “First Interchange” along Sheikh Zayed Road, near Dubai’s main business district.
With a total built-up area of about 6 million sq ft, Burj Khalifa features nearly 2 million sq ft of residential space and over 300,000 sq ft of prime office space, in addition to the area occupied by the keenly awaited Armani Hotel Dubai and the Armani Residences. The tower also features modern lifestyle amenities including clubs, health and fitness facilities, gourmet restaurants and the 124th floor observation deck, ‘At the Top.’
With the final height of Burj Khalifa unveiled, the world now had a new reference point for high-rise developments. Burj Khalifa is an example of collaboration on a global scale, and the tremendous positive energy that can be generated where people from all over the world came together to work towards a common goal. Thousands of professionals and skilled workers from around the world worked on this once-in-a-lifetime project. More than 60 of the world’s leading consultants including South Korea’s Samsung Corporation and New York-based Turner Construction Company, Skidmore, Owings and Merrill (SOM), Hyder Consulting were involved in the project . The total cost for the Burj Khalifa project was about US$1.5 billion; and developed by Emaar Properties.
