Burj Dubai, the iconic tower being developed by Emaar Properties PJSC, has reached a new record height of 688 meters (2,257.2 ft). The tower became the world's tallest after surpassing North Dakota, USA's KVLY-TV mast (628.8 meters; 2,063 ft) in April 2008. Currently at over 160-story, 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 rooftop and the tip of the spire, pinnacle, antenna, mast or flagpole. 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.
