Cesar Pelli, an Argentine-born American architect, created the Twin Towers to house the headquarters of Petronas, Malaysia's national petroleum firm; they were completed in 1998. The office buildings are 838 and 491 feet high, with a total area of 1 million square feet (93,000 m²). The shape of the building is that of two interlocking pyramids, with the upper structure forming a cap over the lower one.
The Petronas Towers have been called the world's tallest oil company towers because of their role as the corporate headquarters for Petronas, the state-owned oil and gas corporation of Malaysia. They are also the highest occupied free-standing structures in the world. At 98 stories and 980 feet (30 meters) tall, the Petronas Towers are almost twice as high as the Sears Tower in Chicago, which is 33 floors tall. They are also taller than the former World Trade Center towers in New York, which were both 91 stories tall.
The Petronas Towers were designed by César Pelli & Associates and built by Haribon Konsortium. The main contractor was TA Global Construction. The cost of construction was estimated at $150 million at the time of completion. However, recent estimates place the cost at $300-$400 million.
Cesar Pelli's PETRONAS Twin Towers are the tallest skyscrapers in Kuala Lumpur, Malaysia. The towers contain 102 floors above ground and have a height of 468 feet (140 m) and 481 feet (145 m), respectively.
The Twin Towers were designed by César Pelli and opened for business in 1998. They are located at the heart of Petronas' financial district and is also regarded as one of the most expensive buildings in Malaysia. The complex cost over $1 billion to build and occupy a plot of land that covers an area of about.
Petronas is a state-owned oil company that is the largest employer in Malaysia. The company created the need for this landmark building by bidding for and winning an international competition held by the World Trade Organization to locate its main office on the Malaysian continent. The project was awarded to PETRONAS and César Pelli in 1996. Construction began that same year and was completed in 1998. The main sponsor of the project was supposed to be the government of Malaysia but due to political reasons they could not come up with the full amount needed so the company stepped in to cover the rest.
The Petronas Twin Towers were formerly the world's highest structures. Cesar Pelli & Associates designed the 88-story twin constructions, which are connected at the 41st and 42nd floors (175m above street level) by a 58-metre-long, double-decker Sky Bridge. The towers were built from 1998 to 2004 as part of a new city center for Kuala Lumpur, Malaysia. They are among the most expensive buildings in the world and have become an icon of Malaysia and Singapore.
The Petronas Twin Towers were also the first skyscrapers to be equipped with air conditioning systems. This was done to prevent any damage to the elevators caused by extreme temperatures. The system uses two million litres of refrigerant per year to provide cooling for the offices on the upper floors.
Also, the Petronas Twin Towers are the only skyscrapers to have a public observatory on top of them. The viewing platform is open daily from 09:00 until 17:00 except on public holidays when it is closed. There is a charge of RM10 for adults, but children under 12 years old go free of charge.
In addition, the Petronas Twin Towers are the largest single-element self-supporting structures in the world. Each tower weighs nearly 20,000 tons and is made up of almost 6 million individual pieces of glass. They are also the tallest reinforced concrete structures in the world.
To symbolize Malaysia's growing riches and the country's wish to be more visible on the international scene, it was decided to construct a pair of iconic 88-story skyscrapers to house the offices of Petronas, the national oil and gas firm. The buildings were designed by Gaudi and Lee (the same team that designed Barcelona's Sagrada Familia Church) and constructed by Skidmore, Owings & Merrill.
The Petronas Twin Towers were meant to be a showpiece not only for Malaysia but for the entire Asia Pacific region. They were the tallest buildings in Southeast Asia when they were completed in 1998. However, since then, many other tall buildings have been built in Bangkok, Manila, and Jakarta so they no longer rank as the highest structures in their countries.
Tall buildings are useful for showing off economic power and influence, and both towers fit this role perfectly. They were meant to be eye-catching advertisements for Malaysia's booming economy, with plans to build more high-rise offices, hotels, and shopping malls around the city. The towers also served as landmarks, helping people find their way around newish town. They were popular with tourists who wanted to get a good view of the city.
The Petronas Twin Towers were technically not twins because they had different heights: 2 World Trade Center is taller by 20 floors.
