Burj Khalifa, Dubai, United Arab Emirates

Burj Khalifa, Dubai, United Arab Emirates

At Burj Khalifa in Dubai, currently the world’s highest building, the HOCHTIEF subsidiary Turner took over the construction management. On 162 floors under one roof there are hotels, apartments, offices and retail. At peak times, 12,000 people from more than a hundred countries have simultaneously worked on its construction. Since the concrete is not allowed to heat up too much during concreting, this work was only performed at night. A continuous pump system and a newly developed liquefier enabled the concrete to be pumped 601 meters upwards without interruption.
