KOREA's Samsung Group is due to complete construction of the world's tallest building next September. The 92-storey KLCC Petronas Tower will stand 446 metres above the heart of Kuala Lumpur in Malaysia. Designed by the world-famous architect, Caesar Pelli, on the site of a former racetrack, the super-skyscraper will be three metres higher than Sears Tower in Chicago - currently the tallest building in the world. Petronas Tower, with 560,000 square metres of office space, will be capable of accommodating 60,000 people. It will also house a convention centre, hotel, a shopping mall and underground parking for 7,000 cars. Connecting the two cylindrical towers on the 41st floor will be the world's highest 'sky bridge' - to make access between the towers easier and provide alternative exits in the event of an emergency. Alongside the main tower will be another, soaring 60 storeys. Samsung is constructing the giant with a consortium led by Hajama of Japan.
