It's official: Skidmore Owings & Merrill's Burj Dubai is the tallest building in the world

July 21, 2007: At 512.1 metres (1,680 feet) and 141 storeys, Burj Dubai is the tallest building in the world. Burj Dubai is now taller than Taipei 101 in Taiwan, which at 508 metres (1,667 ft) has held the tallest-building-in-the-world title since it opened in 2004. Burj Dubai has now reached 141 storeys - more storeys than any other building in the world.On schedule for completion in 2008, Burj Dubai will be the tallest structure in the world in all four of the criteria listed by the Council on Tall Buildings and Urban Habitat (CTBUH). The council measures height to the structural top, the highest occupied floor, to the top of the roof, and to the tip of the spire, pinnacle, antenna, mast or flag pole. The final height and number of storeys, a topic of enthusiastic debate among media and experts alike, has not yet been revealed. But from now on, the tower will set new records for its technical and architectural ingenuity.More than 313,700 cubic metres of reinforced concrete and 62,200 tonnes of reinforcing steel have been used in the tower’s construction so far. Burj Dubai has already set a new world record for vertical concrete pumping for a building by pumping to over 460 metres (1,509 ft). The previous record of 448 metres (1,470 ft) was held by Taipei 101. Reflecting a no-compromise approach to safety, Burj Dubai has been designed to manage the effect of wind and seismic movements. High-strength concrete makes up the tower’s super-structure, which is supported by large reinforced concrete mats and piles. The 80,000 sq ft foundation slab and 50-metre deep piling are waterproofed and feature cathodic protection. Burj Dubai became the tallest building in the world in just 1,276 days; excavation work started in January, 2004. More than 5,000 consultants and skilled construction workers are employed on site, and the world’s fastest high-capacity construction hoists, with a speed of up to 2 m/sec (120 metres/min), move men and materials. Burj Dubai will be at the centre of Downtown Burj Dubai, a US$20 billion, 500-acre downtown development billed as the most prestigious square kilometre on earth.Burj Dubai will feature residential, commercial and retail components including the world’s first Armani Hotel & Residences, exclusive corporate suites, a business centre, four luxurious pools and spas, an observation platform on Level 124 and 150,000 sq ft of fitness facilities.
