Petronas Tower 1 - Kuala Lumpur
Designers and Builders :
Vital Statistics :Due to a lack of steel and the huge cost of importing steel, the towers were constructed on a cheaper radical design of super high strength reinforced concrete together with a steel and glass facade.
Buildings were built on the world's deepest foundations. The 120-meter foundations were built by Bachy Soletanche, and required massive amounts of concrete. Supported by 23-by-23-metre concrete cores and an outer ring of widely-spaced super columns, the towers use a sophisticated structural system that accommodates its slender profile and provides from 1300 to 2000 square metres of column-free office space per floor.
The towers feature a skybridge (constructed by Kukdong Engineering & Construction) between the two towers on 41st and 42nd floors. The bridge is 170 m high and 58 m long. The advanced elevator system of the towers have a total of 78 elevators and all main elevators are double-decker with the lower deck of the elevator taking you to odd numbered floors and upper deck taking you to the even numbered floors. Below the twin towers is Suria KLCC, a popular shopping mall, and Dewan Filharmonik Petronas, the home of the Malaysian Philharmonic Orchestra. Outside the building is a park with jogging and walking paths, a fountain with incorporated light show, wading pools, and a children's playground.
Earthquyake Safety : Special Design Features : Building is designed to resemble motifs found in Islamic art, a reflection of Malaysia's Muslim religion.
