The Petronas Twin Towers (also known as the Petronas Towers or Twin Towers), in Kuala Lumpur, Malaysia were the world's tallest buildings, before being surpassed by the Taipei 101. However, the towers are still the tallest twin buildings and office building in the world. Tower 1 was built by Hazama Corporation and Tower 2 by Samsung Engineering & Construction and Kukdong Engineering & Construction (both of South Korea). They were the world's tallest buildings from 1998 to 2004 if measured from the level of the main entrance to the structural top, the original height reference used by the US-based Council on Tall Buildings and Urban Habitat from 1969 (three additional height categories were introduced as the tower neared completion in 1996).
Constructed : 1992-1998
Antenna/Spire Height : 451.9 m (1,482.6 ft)
Roof Height : 378.6 m (1,242.1 ft)
Top floor : 375.0 m (1,230.3 ft)
Floor count : 88
Floor area : 395,000 m2 (4,252,000 sq ft) (1 & 2)
Elevator count : 78 (1 & 2)
Designed by Argentine-American architect César Pelli, the Petronas Towers were completed in 1998 and became the tallest buildings in the world on the date of completion. They were built on the site of Kuala Lumpur's race track. Because of the depth of the bedrock, the buildings were built on the world's deepest foundations. The 120-meter foundations were built by Bachy Soletanche, and required massive amounts of concrete
Spanning 17 acres below the building is the KLCC park with jogging and walking paths, a fountain with incorporated light show, wading pools, and a children's playground.
Suria KLCC is one of the largest shopping malls in Malaysia.
The towers feature a skybridge (constructed by Kukdong Engineering & Construction of South Korea) between the two towers on 41st and 42nd floors, which is the highest 2-story bridge in the world. The bridge is 170m above the ground and 58 m long, weighing 750 tons. The same floor is also known as the podium, since visitors desiring to go to higher levels have to change elevators here. The skybridge is open to all visitors, but free passes (limited to 1700 people per day) must be obtained on a first-come, first-served basis. The Skyway is closed on Mondays. Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.
