| Emaar's iconic Burj Dubai scales level 50 Global real estate major Emaar Properties marked a milestone in its historic quest to build the world's tallest tower as the AED 3.673 billion (US$1 billion) Burj Dubai scaled 50 levels. This remarkable feat in the construction of Emaar's iconic super tower at the Burj Dubai Downtown development was accomplished in less than 900 days since excavation work started in January, 2004. Work is on course for a 2008 completion with one new level added every four days. Designed by Chicago-based Skidmore, Owings & Merrill (SOM), Burj Dubai is being constructed by high-rise construction experts South Korea's Samsung Corporation, and Turner Construction International is the project and construction manager. Over 3,000 workers are currently working on the Burj Dubai. More than 160,000 m³ of high-quality concrete and 25,000 metric tons of steel rebar have so far been used in the construction. Specially developed concrete pumps are employed to generate 350 bars of pressure and pump to a height of 600 metres. Eleven cranes and the world’s fastest high-capacity construction hoists – with a speed of up to 2 m/sec (120 m/min) - are used to move men and material to the lofty heights. The fast-track construction employs modern building techniques including the use of self-climbing formwork for walls and prefabricated rebar cages. The tower has a base floor plate of 33,000 sq. ft., which tapers as the structure rises skywards. write your comments about the article :: © 2006 Construction News :: home page |
