Petronas Twin Towers
Petronas towers are located in Jalan Ampang, Kuala
The Twin Towers were built on the site of Kuala
Lumpur's race track.
Designed by Argentine-American architect César
Pelli and built by Bachy Soletanche at a cost of US $1.2 billion, the
Twin Towers were the tallest buildings in the world until 2004, when
Taipei 101 took over the title. However, Petronas Towers are still
the tallest twin buildings.
Planning on the Petronas Towers started on 1
January 1992 and included rigorous tests and simulations of wind
and structural loads on the design.
The concrete raft foundation, comprising 13,200
cubic metres (470,000 cu ft) of concrete was continuously poured
through a period of 54 hours for each tower. The raft is 4.6 metres
(15 ft) thick, weighs 32,500 tonnes (35,800 tons) and held the world
record for the largest concrete pour until 2007.
Tower 1 ran into problems when they discovered the
structure was leaning 25 millimetres (0.98 in) off from vertical. To
correct the lean, the next 16 floors were slanted back 20 millimetres
(0.79 in) with specialist surveyors hired to check verticality twice a
day until the building's completion

The Towers measure 378m (1240ft) high, without the
pinnacle and spread over an area of around 341,760 sq. m. (3.7
million sq. ft.).
On the top of each tower is a pinnacle standing 73.5
metres (241 ft) tall.
The sky-bridge of Petronas Twin Towers is at the
41st and 42nd levels, 58.4m (192ft) long and weighs 750 tons.
There are 10 escalators in each building.
The foundations go down as much as 120 m deep.
Interiors were completed on 1 January 1996, the
spires of Tower 1 and Tower 2 were completed on 1 March 1996,
and the first batch of 'PETRONAS’ personnel moved into the
building on 1 January 1997.
The building was officially opened by the Prime
Minister of Malaysia Tun Dr. Mahathir bin Mohamad on 1 August
