Described as both a ‘Vertical City’ and ‘A Living Wonder,’ Burj Khalifa, developed by Dubai-based Emaar Properties PJSC, is the world’s tallest building. Rising gracefully from the desert, Burj Khalifa honours the city with its extraordinary union of art, engineering and meticulous craftsmanship. At 828 metres (2,716.5 ft), the 200 plus storey Burj Khalifa has 160 habitable levels, the most of any building in the world. The tower was inaugurated on January 4, 2010, and is responsible for a number of world-firsts. The tower became the world’s tallest man-made structure just 1,325 days after excavation work started in January 2004. Burj Khalifa utilised a record-breaking 330,000 cubic metres of concrete; 39,000 tonnes of steel reinforcement; 103,000 square metres of glass; and 15,500 square metres of embossed stainless steel. The tower took 22 million man hours to build.
