Petronas Twin Towers,Kuala Lupmur _Designed by MakeGyver ( http://www.thingiverse.com/thing:396418/#files ) _The Petronas Towers, also known as the Petronas Twin Towers are twin skyscrapers in Kuala Lumpur, Malaysia. According to the Council on Tall Buildings and Urban Habitat (CTBUH)'s official definition and ranking, they were the tallest buildings in the world from 1998 to 2004 and remain the tallest twin towers in the world replacing the World Trade Center in New York. The buildings are a landmark of Kuala Lumpur, along with nearby Kuala Lumpur Tower. _The towers were designed by Argentine American architect César Pelli. They chose a distinctive postmodern style to create a 21st-century icon for Kuala Lumpur. Planning on the Petronas Towers started on 1 January 1992 and included rigorous tests and simulations of wind and structural loads on the design. Seven years of construction followed, beginning on 1 March 1993 with the excavation, which involved moving 500 truckloads of earth every night to dig down 30 metres (98 ft) below the surface.
