From the housing stock, the first place in the world before the construction of the legendary Dubai skyscraper belonged to the Taipei 101 skyscraper located in Taiwan. The height of the Burj Khalifa skyscraper is 828 m.

Record building time

Despite the crisis and difficulties with finances, construction was carried out at a record pace. On average, they drove out two floors in seven days.

Burj Khalifa (Burj Dubai) - as of 2015 is the most tall building on the ground. After its construction, all height records were broken:

• the tallest ground structure;
• tallest residential building;
• the largest number of storeys;
• tallest free-standing structure.

More than $1 billion was spent on its construction and up to 12,000 workers were involved at a time. This building has become the centerpiece of a $20 billion project developed by the UAE government that includes an entire complex of multi-storey buildings in Dubai.

The shape and structure of the Burj Khalifa

The entire core of the skyscraper is built around the shape of a three-pointed star that spirals upwards. Who

Up to 12,000 people were involved in the construction at a time

Husband, when designing the building, traditional Islamic outlines were taken into account in order to harmoniously fit into the surrounding landscape and architecture of the region of construction. Thus, the plan of the first floors is the outline of the letter "Y", the petals of which are reduced to the monolithic core of the building, which allows you to combine a strong core for the stability of the entire building and maximum beautiful view from the window for visitors to the hotels that are located here.

About 30 floors of the building are technical and reserved for the needs of various staff and equipment. These technical floors are evenly distributed throughout the building.

At the heart of the tower is a stiffening core in the form of a six-pointed core, from which three spans of the building diverge in the form of petals. The central core of the building ensures its horizontal stability and plays the main axial role. Monolithic diaphragms extend from the core to the end of each span-lobe, which form central corridors. These concrete walls play the role of a connecting web, which makes the entire structure resistant to wind and dynamic loads. Along the perimeter of the building there are columns that complement the monolithic ensemble.

The supporting structures of almost all modern skyscrapers are built of reinforced concrete and end with metal structures, Bursh Khalifa is no exception. The last block of concreting reaches a height of 584 meters, the rest of the building is made of a structural greasy spire with a diagonal system of brackets. The height of the spire was over 180 m.

Foundations of the Burj Khalifa

The foundation of the core of the skyscraper consists of a solid slab 3.7 meters thick. During its production, 12,500 m3 of C50 self-compacting concrete was poured. Monolithic grillages extend from the foundation of the core towards each petal span of the building. Each such grillage has four concreting grips.

In total, the skyscraper supports 194 piles. Specifications piles:

• diameter 1.5m.;
• average length 43m.;

In terms of diameter and length, these piles have become a record that have ever been used in construction at the AOE. During their production

self-compacting concrete C60 was used.

Technological aspects in the construction of the Burj Khalifa tower

During the construction of such a phenomenal structure, the most advanced technologies were applied, many of which were involved

first. The building's load-bearing diaphragms were cast using Doka's SKE 100 automatic self-advancing formwork systems, while the floor slabs were produced using MevaDec formwork systems. The average construction cycle of one block (floor) was 2.5 days. The total weight of the reinforcement used in the construction of the Halfa tower was more than 60 thousand tons. All the reinforcement of the load-bearing diaphragms was pre-prepared in the workshops, which made it possible to carry out quick installation at the top.
Three Favelle Favco self-retracting cranes were mounted inside the core on different height each doing their own amount of work. These taps were specially

Completion of construction

designed for this object, their technical characteristics:

• load capacity 27.5 tons;
• lifting speed up to 120 m/min;
• hook reach on a horizontal boom more than 50 m.

Throughout the entire period of erection of the supporting structures, the verticality of the structure was monitored using a GPS system using satellites.
During the construction of the Khalifa Tower, a record was set for pumping concrete to a height of more than 600 m.,

The final height of the Burj Khalifa was kept secret until the last moment and was announced only at the ceremonial commissioning of the building and amounted to 828 m.

On January 4, 2010, the ruler of the emirate, Mohammed bin Rashed Al Maktoum, opened the tower Burj Khalifa In Dubai. At first it was called Burj Dubai, but then it was renamed in honor of the President of the United Arab Emirates - Sheikh Khalifa bin Zayed Al Nahyan.

Tower construction history

Construction plans highest structure in the world were announced back in 2002. It was planned that the tower will become a key element of the area under construction and will attract tourists from all over. the globe. The South Korean company Samsung Engineering became the general contractor of the building, and the Dubai-based Emaar became the developer.

The construction of the tower lasted six years and required about one and a half billion dollars. By the way, they paid off in record time - 1 year.

While still under construction, the area of ​​the building was sold at $40,000 per square meter. The observation deck has also gained immense popularity, which can now be accessed by purchasing a ticket. The construction of the tower began in 2004. The building was erected quite quickly: one, two floors every week.

A special brand of concrete, designed specifically for the Burj Khalifa, can withstand very high temperatures - up to plus 50 degrees Celsius. It was poured only at night, adding ice to the solution. Having reached the one hundred and sixtieth floor, the concrete work was completed. Further, according to the plan, a spire was assembled from metal structures, the height of which was one hundred and eighty meters.

Much attention was paid to the fire safety system, which allows the evacuation of all those in the building in no more than thirty-two minutes.

In the spring of 2006, the cruelty of the guards provoked a pogrom at the construction site of the future Burj Khalifa tower in Dubai. Two and a half thousand workers, unable to endure the chicanery of the guards, beat them, and then, in a fit of anger, they began to smash the construction headquarters, burn branded cars, smash equipment, break into safes. The next day, they demanded that Al Naboodah Laing O'Rourke's employer raise wages and improve working conditions, otherwise they threatened to go on a long-term strike. Numerous builders of the new airport terminal also joined the workers.

It turned out that the height of the tower could be higher. Surprisingly, the endless upward growth was stopped not by technical, but by economic reason: in order to find funds to continue construction, it was necessary to sell a large number of residential areas. Perhaps that is why this building has such a slender silhouette.

The tower was scheduled to open on September 9, 2009 along with the Dubai Metro. However, the financial problems of the developer prevented this. The solemn event took place in early January of the following year.

Features of the skyscraper project

The Burj Khalifa tower (its height, by the way, is 828 meters), was built according to the “city within a city” project, authored by Adrian Smith, an American architect with experience in designing similar structures.

Being in fact the core element of the new business center in Dubai, the building was created on the principle of a vertical city. The floors in it are arranged in blocks and have different functions. Thirty-five of them were given to offices, thirty-seven - to rooms and suites of the hotel, the design of which was developed by Giorgio Armani himself.

There are shopping centers and about nine hundred apartments. The hundredth floor with three apartments of 500 square meters was bought at his disposal by the Indian billionaire B. R. Shetty.

The artificial tower rising above the main building, in addition to the decorative function, also has a communication function, because it is equipped with modern telecommunications equipment. Three floors underground are occupied by a parking lot that can accommodate three thousand cars. A 61 meter long turbine is installed, rotated by the wind, and solar panels an area of ​​approximately 15 thousand meters. All this was done so that the tower could independently produce electrical energy for itself.

The building was equipped with special sun protection and reflective glass panels that reduce indoor heating. And this, in turn, reduced the need for air conditioning. The air conditioning system of the building itself is quite unique. Air flow is carried out throughout the tower from the bottom up. At the same time, underground modules and sea water are used for cooling.

The building has about sixty elevators with a speed of up to 65 km/h. In less than a minute you will be on top of the tallest building in the world.

The tourist part of the tower has magnificent interiors. On the one hundred and twenty-second floor is the restaurant "Atmosfera" for eighty seats.

On one hundred and twenty-third and one hundred and twenty-fourth there is a lobby and a beautiful observation deck. The latter is located at a height of five hundred and five meters from the base. Most of its glazed. Visitors have the opportunity to view the surrounding space through electronic telescopes.

In addition to the real picture through computers with cameras installed on the floor, a record of the historical, day and night panorama of Dubai is viewed.

You can stay on the observation deck as much as you like, but getting there is not so easy. Tickets should be purchased in advance as they sell out very quickly. From the observation deck, accessible to tourists, opens great view cities. You can see the old part of it, the port, Dubai Creek, airport, Sharjah.

Before famous tower there is a huge (12 hectares) artificial lake in which there is a beautiful musical fountain, which is illuminated by 6600 light sources and 50 spotlights. The length of this majestic source is two hundred and seventy meters, the height of the jets is one hundred and fifty. The sounding music is made up of Arabic and world works.

The Burj Khalifa in the video is a magnificent sight. But it is even more amazing to see all this beauty with your own eyes by visiting the world's tallest skyscraper in Dubai.

Faktrum tells Interesting Facts about the Burj Khalifa.

1. The tallest building in the world

2. Inside the building

Those who think that the Burj Khalifa is very impressive from the outside, simply have not been inside a skyscraper. The highest observation deck is located at an altitude of 452 meters. In total, the building has 164 floors, 1 of which is underground, and as many as 58 elevators that travel at a speed of 10 meters per second (these are one of the fastest elevators in the world). Also Burj Khalifa has 2957 parking spaces, 304 hotels and 904 apartments.

3. The skyscraper was designed by the Americans and built by a South Korean company.

While the Burj Khalifa is located in Dubai (the original name of the skyscraper is Burj Dubai), the building was designed by the American firm Skidmore, Owings and Merrill. Engineers from Chicago have created a special support structure that resembles a three-pointed star. The construction of the building was entrusted to the South Korean company Samsung Engineering and Construction.

4. Multiple records

This is the highest free standing building, the building with the highest residential floor, the building with the most floors, the building with the highest elevators and the second highest observation deck (the highest observation deck is located in the Canton TV Tower).

5. What was needed for the construction

In order to build such a titanic building, it took a lot of time and effort (namely, 6 years and 22 million man-hours). On especially busy days, more than 12,000 workers were at the construction site at a time.

6. Huge weight

It took to build the building incredible amount materials. One aluminum went so much that it would be enough to create 5 A380 Airbuses. 55,000 tons of reinforcing steel and 110,000 tons of concrete were also spent. This is approximately equal to the weight of 100,000 elephants. And if you take and fold the reinforcement from the building in a row, then it would stretch for a quarter of the Earth.

7. Heat resistance

It's very hot in Dubai in summer average temperature here is 41 degrees. Naturally, a building built in this country must withstand extreme temperature fluctuations. That is why over 300 Chinese experts were hired to develop a cladding system that can protect against local temperatures.

8. Power consumption

Naturally, living in such a huge building requires a monstrous amount of resources. For example, the Burj Khalifa uses about 950,000 liters of water every day. The building also consumes a huge amount of electricity (about as much as 360,000 hundred-watt light bulbs “eat up”).

9. Washing a skyscraper

How do you clean and wash 26,000 glass panels that always look perfect? Responsible for this are 12 machines, which weigh about 13 tons each, moving along special rails on the outside of the building. The cars are serviced by 36 people.

10. Floral design

The design of the Burj Khalifa was inspired by the hymenocallis, a flower that has long petals radiating from the center. The three wings of the Burj Khalifa diverge to the sides like these petals.
