THE construction of Asia's tallest building and the new business district where it is located have a symbolic importance for Malaysia, according to a Kuala Lumpur industry source. The 545.31-metre-high 88-storey Petronas Twin Towers complex is expected to be completed in 1997. It will also be the largest twin tower construction in the world. Built at a cost of US$784 million, the towers will be connected by a bridge on the 41st and 42nd floors. The building's owner, state oil company Petronas, will occupy most of the 2.5 million square feet of office space. Each tower has been designed in the shape of eight-pointed Islamic stars. The towers are seen as a symbol of Malaysia's rapid economic development. Malaysia's GDP has expanded by more than eight per cent a year for the past seven years. The towers are part of a government-backed development of 22 high-rise buildings set on 40 hectares in central Kuala Lumpur. The development is called the Kuala Lumpur City Centre (KLCC) project.
