Petronas Twin Towers

Kuala Lumpur


Rising side by side in parallel glory, the Petronas Twin Towers honor Malaysia's past while celebrating its emergence as a global commercial centre. To achieve his client's vision, the renowned architect César Pelli used the shapes of traditional Islamic architecture and gave them a postmodernist flair.

Built to house the headquarters of Petronas, the national petroleum company of Malaysia, the towers are extraordinarily slender by engineering standards - a fact that created special challenges for Otis.

Without enough space for the conventional configuration of side-by-side lift hoistways, Otis devised a system of double-deck lifts to reduce the number of hoistways needed. The towers are equipped with 58 double-deck lifts and 18 single lifts.

The towers are clad in panels of glass and stainless steel, creating an effect that Pelli called "multifaceted diamonds sparkling in the sun."

The floor-plate of each tower is formed by two interlocking squares with small circular infills. These geometric figures are said to symbolise unity, harmony, stability and rationality - all important principles of Islam. The towers feature a series of setbacks as they taper skyward to a height of 452 metres.

Cursă contra timp

Guvernul malaezian a dorit ca această clădire să fie finalizată în șase ani. Pentru a respecta termenul impus, au fost angajați două firme de construcție - una sud-coreeană şi una japoneză - fiecare fiind responsabilă pentru unul din turnuri.Urmând ca frma care termină prima să câştige dreptul de a construi Skybridge. Echipajul sud-coreean a câştigat această cursă prin completarea turnului 2 (turnul de est).

Skybridge

Skybridge-ul, de 58,4 metri lungime, este susținut de arcuri înșurubate la nivelul 29 al fiecărui turn.

Nivelul inferior este deschis publicului, dar biletele sunt limitate la aproximativ 1.000 de persoane pe zi. Nivelul superior este rezervat chiriasilor turnurilor. Skybridge găzduieşte şi o sală de conferințe, o sală de mese și o sală de rugăciune.

Quick facts about the Petronas Twin Towers

At 452 metres, the towers were the first buildings outside the United States to claim the title of the world's tallest, succeeding the 442-metre-high Willis Tower in Chicago. They remain the world's tallest twin towers.

When Tower 2 reached the 72nd floor, engineers discovered it was leaning about 25 millimetres off vertical - or nearly an inch. To correct the lean, the next 16 floors were slanted back 20 millimetres. Surveyors checked verticality twice a day until the building's completion.

Built over a former racetrack, the Petronas Towers also include shopping and entertainment facilities, a petroleum museum and a concert hall that is home to the Malaysian Philharmonic Orchestra.
