The developer claims the tower became the world's tallest after surpassing North Dakota, USA's KVLY-TV mast (628.8 metres) in April 2008. At over 160 storeys, the tower also has the largest number of floors in any building. When completed, Burj Dubai will meet all four criteria listed by the Council on Tall Buildings and Urban Habitat (CTBUH), which classifies the world's tallest structures.   CTBUH measures the height of buildings to the structural top, the highest occupied floor, the top of the roof and the tip of the spire, pinnacle, antenna, mast or flag pole. Designed by Chicago-based Skidmore, Owings & Merrill (SOM), Burj Dubai is constructed by high-rise experts South Korea's Samsung Corporation. Turner Construction International is the project and construction manager.
