Interesting facts Burj Khalifa

According to ancient legend, a long time ago, builders, to make a name for himself We decided to erect a tower to heaven, but to finish building the tower of Babel did not manage to... Especially interesting modern approach to the construction of skyscrapers.

As you know the United Arab Emirates are renowned worldwide for its extensive oil reserves and high standard of living. But in 2010 - this state has become famous for another attraction - the tallest building in the world, built in the city of Dubai.

But apart from a height of 828 meters skyscraper Burj Khalifa broke two more records: becoming the most expensive building in the world - total construction budget exceeded 1.5 billion dollars, as well as breaking the world record for the number of floors - they are in the building 160.

But to understand the full extent of the construction is necessary to go back a few years ago, and look back at the beginning of the massive construction begun on the orders of the Emir of Dubai Mohammed bin Rashid.

It is known that the palm in the construction of skyscrapers deservedly belongs to Americans accustomed to build high-rise buildings on the rocky grounds, but the engineers and architects of Chicago firm SOMWhose services were used by customers in the UAE, it was possible the seemingly impossible - to erect in the wilderness is the tallest building in the world.

As strange as it may sound, but in such a huge building is no foundation in the usual sense.

The secret is simple - the building stands on stilts. According to one of the architects of the project, in this case it was the only way out, so in the desert to find the rocky soil, in contrast to New York can support the weight of this structures.

The builders have gone their own way, screwing over 200 piles with a diameter of 1.5 meters and 45 meters long. Thus,via screw-drivingWe managed to solve two problems at once - compacted soil and provide a reliable basis skyscraper.

According to rumors, leaked to the press, the plans were to construct a building height of 1 kilometer, but after laying the foundation and the erection of the first floor customers wisely decided to limit the height of a little more than 800 meters.

An interesting fact is that the skyscraperBurj Khalifa, his name is obliged broke out in 2008 the global financial crisis. Customers from Dubai had to ask for additional financial support to the neighboringEmirates - Abu Dhabi. Therefore, in gratitude for the received billions, the tower was renamed toBurj Dubai inBurj Khalifain honor of the Sheikh of Abu Dhabi.

Construction was carried out 24 hours 7 days a week. Number of invited architects and engineers was about 100 people, while the number of workers who worked on the construction of the century has passed for 12,000 people.

New Tower of Babel was growing at a rate of one floor for three days. Using concrete structures and principles of monolithic construction workers and architects managed do the impossible - to build the seismic stability of the building could withstand strong earthquakes. But, as told to the designers, one of the main problems in the construction of steel strong winds blowing from the Arabian Gulf.

It winds tower owes its futuristic shape. She seemed to consist of several columns, terraces flowing one into the other. And to minimize the force of the wind terraces were built on the principle of the spiral.

In addition, the designers of the building had to deal with a lot of unexpected problems - from the precise positioning of the center of the building of concrete required to fill - to this end, GPSnavigatorov signals used to select glass panels made of highly durable glass which simultaneously efficiently reflects heat and transmits sunny shine.

Also skyscraper building is completely non-volatile. For this purpose, a complex of solar panels and a special pride of engineersvetrovayaturbinaheight of 61 meters! And the skyscraper is clearly visible even from a distance of 90 kilometers.

As used convection ventilation system which drives off air flow from the bottom to the top of the building.

The air is cooled with seawater and underground blocks filled with refrigerant. A Lightning protection applies the most advanced lightning protection system.

The project Burj Khalifa became the embodiment of the concept of the future of these structures, namely, the "city within a city." When the building combines commercial and educational centers, residential apartments, becoming a fully autonomous and energy-efficient urban complex.
