Designed to be a city within a city, the 100-acre site hosts the tallest twin buildings in the world, shopping mall, hotels, office buildings and several hotels. A public park and a mosque is also built on the area and open to everyone. The whole project is cooled via district cooling located on the property.
History
Kuala Lumpur City Centre was officially completed on 1 January 1996 based in Petronas Towers.
Kuala Lumpur City Centre was officially renovated on 1 January 1997 based in Petronas Towers.
Kuala Lumpur City Centre was officially opened to public on 1 January 1998 based in Petronas Towers.
Kuala Lumpur City Centre was officially inaugurated by the 4th Prime Minister of Malaysia's Tun Doktor Mahathir Bin Mohamad on National Day of Malaysia (31 August) in 1999 at 8:30 pm based in Petronas Towers.
The Petronas Towers, also known as the Petronas Twin Towers (Malay: Menara Petronas, or Menara Berkembar Petronas) are twin skyscrapers in Kuala Lumpur, Malaysia. According to the CTBUH's official definition and ranking, they were the tallest buildings in the world from 1998 to 2004 until surpassed by Taipei 101, but they remain the tallest twin building in the world.[2] The buildings are the landmark of Kuala Lumpur
Skybridge
The towers feature a double decker skybridge connecting the two towers on the 41st and 42nd floors, which is the highest 2-story bridge in the world.[25] It is not attached to the main structure, but is instead designed to slide in and out of the towers to prevent it from breaking,[26] as the towers sway several feet[specify] in towards and away from each other during high winds. It also provides some structural support to the towers in these occasions. The bridge is 170 m (558 ft) above the ground and 58 m (190 ft) long, weighing 750 tons.[27] The same floor is also known as the podium, since visitors going to higher levels have to change elevators here. The skybridge is open to all visitors, but tickets are limited to about 1000 people per day, and must be obtained on a first-come, first-served basis. Initially, the visit was free but in 2010, the tickets started being sold by Petronas. Visitors can choose to opt for package one which is just a visit to the skybridge or go for package two to go to the skybridge and all the way to level 86.[28] Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.[29]The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower.[30] The total evacuation triggered by a bomb hoax on 12 September 2001 (the day after the September 11 attacks destroyed the twin towers of the World Trade Center in New York City) showed that the bridge would not be useful if both towers need to be emptied simultaneously, as the capacity of the staircases was insufficient for such an event.[31] Plans thus call for the lifts to be used if both towers need to be evacuated, and a successful drill following the revised plan was conducted in 2005.
There is a three-hinged arch that supports the skybridge with arch legs, each 51 metres (167 ft) long, that are bolted to level 29 of each of the towers.[22] After being constructed on the ground, the skybridge was lifted into place on the towers over a period of three days[EBSCO 1] in July 1995[22] but instead of being directly connected to the towers, the skybridge can shift or slide in and out of them in order to counterbalance any effect from the wind. In addition to being a cornerstone in the structural stability of the towers, the skybridge is also a device that can be employed during an emergency fire evacuation, providing an escape to the people in the upper floors of the affected tower to the other.[EBSCO 3] Residing on the 41st and 42nd floors, the skybridge connects a conference room, an executive dining room and a prayer room.[EBSCO 1]
