Dubai’s Burj Khalifa: specifications and height
The Burj Khalifa, located in Dubai, is a massive structure that climbs into the sky. The building is enormous, intimidating, and a show-stopper to be appreciated from below, yet it is also light and refined in a way that few other buildings in the world can match. The result is an architectural masterpiece that is unsurpassed in its scope and quality. And this, it should be stressed, is not simply in reference to the height of the Burj Khalifa, which was unthinkable only a short time ago. Given the size of the building, it’s not surprising that many people refer to it as a “vertical city,” as it contains hundreds of private apartments, hotels (including the world-famous Hotel Armani, which is located on the thirty-seventh floor), a massive gym, a swimming pool, numerous restaurants, and even a mosque on the top floor (which, not by chance, holds the record as the highest mosque in the world).
Dubai’s Burj Khalifa skyscraper, the highest in the world
What is the total number of floors in the Burj Khalifa? What is the height of the building? What was the total cost of construction? These are the standard questions that people have when they hear about the spectacular tower that towers over Dubai’s business sector. Not only is the Burj Khalifa the tallest skyscraper in the world, with a total of 160 floors, it is also the tallest building ever constructed by man, standing at 2,722 feet tall and consisting of 160 stories. The cost of its construction is proportional to the size of the structure.
Aside from the Burj Khalifa, the Taipei 101 was the world’s tallest structure prior to its construction.
Due to the fact that it is over 656 feet taller than the second-tallest skyscraper in the world, the record set by Dubai’s Burj Khalifa appears to be unassailably secure.
The previous record holder was the iconic Warsaw Radio antenna, also known as the Konstantynów Radio Tower, which was completed in 1974 to a height of 2,120 feet and was the tallest structure in the world.
Burj Khalifa: construction and architect
After a few setbacks, construction on Dubai’s Burj Khalifa began on the 21 September 2004 and was finished on the 1 October 2009, with the formal inauguration ceremony and public opening taking place a few months later, on the 4 January 2010, respectively. In charge of the project was the Chicago-based architectural firm Skidmore, Owings and Merril, which was formed in 1936 and is widely regarded as one of the most prestigious in the world. SOM specialized in the design of high-rise structures from the beginning, and it quickly rose to become the world’s leading firm in the field of skyscrapers.
- Adrian Smith was in charge of coordinating the group of engineers and architects.
- It is owned by Emaar Properties, and its construction was sponsored by Sheikh Mohammed bin Rashid al Maktoum, Vice President and Prime Minister of the United Arab Emirates from 11 February 2006 to the present, as well as the Emir of Dubai and the majority shareholder in Emaar Properties.
- Interestingly, the exact height of the skyscraper was not immediately revealed: in order to deceive potential competitors, rumors were published that the building’s peak would be 2,683,73 feet, which was more than 32,80 feet lower than the building’s true elevation.
- The world record for height, on the other hand, was broken in 2008, when the Taipei 101 tower, which was previously the highest building on the planet, was surpassed.
- It was only via the significant economic involvement of the Emir of Abu Dhabi and President of the United Arab Emirates, Khalifa bin Zayed Al Nahyan, that the construction project could be completed on time.
As a matter of fact, it was in honor of the Emir that the tower was given the name Burj Khalifa rather than its original name, Burj Dubai (which translates as “Tower of Dubai”).
Some facts about the Burj Khalifa Tower
Almost all of the statistics surrounding the Burj Khalifa building are mind-boggling to consider. Not just in terms of its size and expense, but also in terms of its height. It took around 12,000 employees to complete the construction of the structure, which has a total surface area of 3,702,785 square feet. In order to go from one level to another, there are 58 lifts and 8 escalators; the lifts travel at 24,85 mph, which is a slower pace than the high-speed lifts of Taipei 101, which whizz up and down at 37,28 miles per hour.
The Burj Khalifa in Dubai can be viewed from a distance of 60 miles away, in all of its splendor.
Specifications of the skyscraper
The “Y” layout of the Burj Khalifa, which is made up of three parts organized around a central core, was inspired by the shapes of the “hymenocallis” flower, which grows in the desert and is visible from space. The towering central core, which culminates in the cathedral’s soaring spire, emerges from within it. The interiors of the Burj Khalifa were designed by Nada Andric, and the most prominent components include glass, black, polished stone, stainless steel, and Venetian plaster walls. Glass is the dominant material throughout the building.

It is estimated that the Dubai Creek Skyscraper will cost AED3.67 billion (US$1 billion) to construct and is projected to be finished by 2022 at the earliest, although the exact completion date is uncertain at this time because to the COVID-19 epidemic. The tower is now on hold due to the pandemic. The skyscraper was formerly called as The Tower in Dubai Creek Harbour, which was a misnomer. Although the exact height has not been revealed, project developer Emaar has said that a minimum height of at least 828 metres (2,717 feet) is required, which corresponds to the height of the Burj Khalifa, Dubai’s tallest skyscraper, as a minimum requirement.
The engineering firm Aurecon, which is working on the project, has indicated that Dubai’s new tallest skyscraper would generate a ‘beacon of light’ from its summit at night, according to the company. According to a statement from engineering firmAurecon, which is collaborating with Spanish architectSantiago Calatrava on the project, the top of the building will have an oval-shaped bulb hosting 10 observation decks, including The Pinnacle Room, which will provide 360-degree views of the city. According to Adrian Jones, project director for The Tower at Aurecon, “The Tower will test the artistry of Aurecon as we play our part in leaving an imprint on the constructed fabric of mankind.” The opportunity to collaborate on this project with Santiago Calatrava and Emaar Properties has been an amazing honor, and we have put together a fantastic team to bring this vision to fruition,” says the team.
An eye-catching net of steel cable stays will connect to a central reinforced concrete core that will extend into the sky, creating a striking visual effect.
Earlier this month, on January 15, 2017, a redesigned replica of the original design was unveiled inside the complex’s Customer Service Center.
In February 2017, a drawing of the Tower surfaced on the internet, depicting it as a structure supported by cable systems. It was also reported in one piece that the skyscraper will be known as Creek Tower, which is a fitting name.
Construction on the skyscraper began in October 2016, with an expected completion date of 2025. Mohammed bin Rashid Al Maktoum was present for the groundbreaking ceremony, which marked the beginning of the tower’s construction. In August 2017, a film showcasing the progress of the building was published. BESIX subsidiary Six Construct finished laying the foundations for the Tower in May of this year. It was not until after the foundations had been completed that the main body of the tower began to be constructed.
Emaar Properties, the developer of the Tower and surrounding region, said on April 4, 2020 that development will be temporarily paused because to the COVID-19 epidemic.
On or around July or August 2020, the project’s website was updated to delete all references to the skyscraper, including renderings of the structure.

Dynamic Tower Hotel
YouTube reveals that this 80-story hotel is a completely rotating tower, making it every bit as dynamic as its name would indicate. It takes 90 minutes to revolve each level completely around its axis of rotation. Residents of the Dynamic Tower Hotel, who are fortunate enough to call it their home, have the ability to significantly alter their surroundings with the touch of a button. Each individual residential unit has the capacity to rotate independently, and the speed and direction of rotation may be regulated from within each individual space.
It will cost you anything from $4 million to $40 million to live here, depending on the level and height that you choose to live on.
Burj Al Arab
There is absolutely no other hotel in the world that is as extravagant and magnificent as the Burj Al Arab, and it is impossible to compare it. This icon of luxury, which has been dubbed “the world’s first 7-star hotel,” is located on a man-made island and, according to Money Control, cost a whopping $1.7 billion to build. The most basic of the 202 rooms offered may be hired for $2,000 per night, making it the most affordable option. The Royal Suite, on the other hand, offers a really unforgettable experience and costs around $24,000 for a one-night stay.

The World’s Tallest Tower Is Estimated to Cost $1 Billion
Following months of speculation about the possibility of developing the world’s tallest building in Dubai, Sheikh Mohammed bin Rashid Al Maktoum, the country’s prime minister, recently officiated the groundbreaking ceremony for the Tower at Dubai Creek Harbor, which will be the world’s tallest structure. The waterfront construction, which being built in partnership by Emaar Properties and Dubai Holding, is planned to exceed previous world’s highest structures such as theTokyo Skytree (2,080 feet) and the Burj Khalifa (2,722 feet) to become the world’s tallest skyscraper (3,045 feet).
It will be similar in design to the Burj Khalifa in that it will contain a mix of luxury residences (such as Dubai Creek Harbour, which will include Dubai Canal Residences, Creekside 18, Harbour Views and Creek Horizon in The Island District) as well as commercial spaces geared toward travelers and business executives.
A press release states that Dubai Creek Harbour will be “the smart hub of the next generation,” with some of the most exciting features including the latest design and engineering innovations as well as artificial intelligence and environmental sustainability elements that will contribute to a “advanced digital lifestyle.” Because there are no other constructions like this in the world, one of the most difficult issues for Emaar Properties will be ensuring the structural integrity of the building.
As a result, the team conducted groundbreaking wind-engineering testing and seismic assessments to ensure that the structure would remain stable under a variety of scenarios.
Tarik Rakha, Assistant Professor in the School of Architecture at Syracuse University, warns that when evaluating projects that make so many lofty claims, it is important to exercise care.
In contrast to the building of Ground Zero, which was explicitly characterized by Daniel Libeskind to Arch Daily as the ” ‘healing of New York,’ a “place of recollection,’ and “a location to witness the resiliency of America,'” the motivation for the construction of The Tower in Dubai is less evident.
“Is there anything greater for Dubai than keeping its distinction as the world’s highest tower?” the expert inquired.
While the economic repercussions of these developments should be a source of worry, there are certain advantages to the tower, as well as some disadvantages.
“It is likely that the use of materiality, structural patterns, and attention to scale will spark intriguing discussions—whether favorable or critical—about a building that will be known as the world’s tallest,” Rakha stated.

The Burj Khalifa and the Khalifa It is also called Khalifah, and it is a mixed-use skyscraper in Dubai, United Arab Emirates, that is the world’s highest building, according to all three of the primary criteria by which such structures are assessed (seeResearcher’s Note: Heights of Buildings). The Burj Khalifa (also known as the “Khalifa Tower”), also known as the “Burj Dubai” during construction, was formally named in honor of Sheikh Khalifa ibn Zayed Al Nahyan, the ruler of the neighboring emirate of Abu Dhabi.
- The tower, whose planned height was kept a tightly guarded secret during its construction, was completed at 162 floors and a height of 2,717 feet.
- A Chicago architectural company, Skidmore, Owings, and Merrill, was tasked with designing the building.
- Baker as a structural engineer.
- Engineers tackle real-life challenges across the world, such as how to build aircraft, buildings, and suspension bridges, by using their knowledge and skills.
- Built on a three-lobed footprint that is an abstract depiction of the native Hymenocallisflower, the structure is modular in design and constructed of prefabricated components.
- It is supported by a sequence of wings, each having its own concrete core and perimeter columns, which surround the hexagonal center core.
- The central core emerges at the summit of the tower and is completed with an extension that extends more than 700 feet into the sky (200 metres).
- During construction, the tower was supported by a reinforced concrete mat almost 13 feet (4 metres) thick, which was in turn supported by concrete piles measuring 5 feet (1.5 metres) in diameter at the fundamental level.
- The outer cladding of the skyscraper is made up of aluminum and stainless-steel panels, vertical stainless-steel tube fins, and more than 28,000 hand-cut glass panels, among other materials.
- In January 2010, the Burj Khalifa easily overtook the Taipei 101 building in Taipei, Taiwan, which stood at 1,667 feet (508 metres) tall and was the world’s tallest structure at the time of its opening.

Confusing The Wind: The Burj Khalifa, Mother Nature, and the Modern Skyscraper
The Grand Hyatt San Francisco will greet you at the front desk with a pleasant sign informing you that the 35-story tower may creak slightly as it glides softly back and forth in the breeze. The hotel has assured guests that this anomaly is not indicative of a structural concern, but tourists have still voiced their dissatisfaction with the situation. According to one angry and restless client who left a review of the hotel, “the building CREAKS!” 1 “It sounds like you’re aboard a ship that’s been around for a while,” comments another.
Since the completion of the 10-story steel-framed Home Insurance Building in Chicago in 1885, which was the world’s first skyscraper, architects have had to consider wind stress, sometimes known as “wind loading,” as they’ve raised the height of their structures.
When completed, the Burj Khalifa, originally known as the Burj Dubai, will soar into the sky as if it were a bolt of lightning, dwarfing the neighboring towers in its path.
(In comparison, the Burj is roughly equal in height to the Taipei 101, with the Chrysler building placed on top.) The tower, which stretches more than half a mile from its base to the tip of its spire, redefines the word “supertall,” which is often assigned to skyscrapers that rise more than 1,000 feet above the ground.
- Building’s spire is composed of multiple different stalks, each of which rises unevenly from the ground surrounding the center spire.
- Even with this strategic design, the 206-story Burj Khalifa will continue to swing slightly back and forth by around 2 meters at the very top of the structure.
- 4 The Taipei 101 skyscraper, which rises 1,667 feet tall and is located almost four thousand miles away near the coast of Taiwan, is now a distant second.
- The sphere, which is gold in hue and weighs 730 tons, softly swings back and forth, balancing the tower against the forces of the wind and insuring the comfort of those who inhabit it.
- Because of the height and mass of each individual tower, the size and shape of each damper must be “adjusted” to compensate.
- It works in the same way as shock absorbers on a car reduce road bumps by swinging or sliding back and forth in the opposite direction.
- 6 According to Carol Willis, director and curator of the Skyscraper Museum in New York, while designing a skyscraper, care for the wind must be taken into account.
- Designers fight a never-ending war against the relentless wind by employing both structural and mechanical solutions, such as the Burj Khalifa’s strategy of “confusing the wind,” and mechanical solutions, such as the tuned mass damper.
- Gravitational forces can only pull a skyscraper in one direction, and it’s a predictable one at that: down.
- When a structure is designed properly, it may be thought of as a “big sail” that has a large surface area against which the wind can force.
8 ‘This results in a regular, or periodic, force,’ says Garber, “that pulls the building from one side to the other across the direction of the wind flow.’ The frequency at which this occurs will vary depending on wind speed, and if those vortices can coincide with the frequency at which the building want to vibrate, then some really enormous forces can be created.” Buildings, like a guitar string, have a natural or resonance frequency at which they are prone to vibrate, similar to the frequency of a guitar string.
- Wind vortices will only have a major impact on a structure if the frequency of the vortices is precisely aligned with the frequency of the building, much as an opera singer must reach the proper pitch in order to break a wine glass.
- As a result of this phenomenon, one of the most important goals in skyscraper design is to disrupt the ordered flow of wind around the structure.
- Due to the fact that all of those things can’t take place at the same time, you’re left with a very little amount of vortex shedding.” If the wind stress caused by vortex shedding is not appropriately controlled, it has the potential to cause significant structural damage or even collapse.
- When skyscrapers are designed, engineers take into consideration a 50- or 100-year return rule.
- Designers then boost the strength of the structure by an additional 60 percent or so, just to be safe, to allow for the possibility of measurement errors.
- 9 Still, wind stress may cause a variety of issues in high-rise structures of different shapes and sizes.
- Additionally, it might provide a swaying sensation that is disconcerting, if not nauseous.
“If the building is moving too much, you can hear it creaking.” “Excessive movements, on the other hand, are the most often expressed worries.” People may report that they can feel the building shifting, or they may even become ill as a result of the movement.” At least such was the situation at the previous GulfWestern headquarters in New York City.
- Additional complaints came from office workers on the top levels who were experiencing motion sickness when the wind picked up speed.
- 11 Indeed, steps to counteract the wind are done as much for the sake of comfort as they are for the sake of safety.
- “People are more sensitive to wind than structures are,” says the author.
- Not only do wind speeds rise with altitude, but the force of the wind also increases with the square of its velocity, as can be seen in the graph below.
- “The amount of motion you’d anticipate in a structure,” adds Garber, “is on the order of 1/200 to 1/500 times its height.” This translates into approximately two to four meters in height for the Burj Khalifa.
- Therefore, one of the primary concerns of architects and engineers is acceleration, which has the potential to produce perceptible forces on the human body.” Forces are frequently expressed in terms of “g’s” in the context of carnival rides, automobiles, and airplanes.
- We’re talking about milli-of g’s force when it comes to looking at buildings, explains Garber.
Humans are capable of sensing accelerations as small as 5 to 25 milligs, which is far less than the maximum force that the structure can withstand.
During the initial design phase of a skyscraper, it is subjected to extensive wind tunnel testing.
(RWDI), a world-renowned wind engineering consulting business, has been in charge of the testing.
Wind engineering specialists are provided with detailed architectural blueprints of the project prior to construction, and a team at RWDI goes to work developing a complicated, stiff scale model for testing.
For example, the 1:500 scale replica of the Burj Khalifa features 1,140 individual pressure taps for gathering data on the wind speed and direction.
Instead of testing airplane wings, sporting equipment, and other minor projects in wind tunnels, these boundary layer wind tunnels are designed to model variations in wind speed with height and may recreate the changing wind situations in which the structures will eventually be built.
Afterwards, all of this information is loaded into computer models, which are used to do more analysis.
In the end, this procedure of wind testing gives structural engineers with a more sophisticated understanding of wind loads than they would otherwise have. Continued on the following page »

Vanity height: how much space in skyscrapers is unoccupiable?
With space becoming increasingly scarce, skyscrapers provide an effective method to build residences and workplaces without leaving a significant environmental legacy. It is intriguing, then, that there are so many buildings that are filled with warm air. In the drive to create the tallest structures possible, architects have resorted to antennas and pointed spires, resulting in skyscrapers that are not so much effective uses of space as they are overdone vanity projects. Take, for example, the Burj Khalifa in Dubai, which is the world’s tallest structure.
The Burj al Arab, which is also located in Dubai, is far worse in this regard, with 39 percent of the total structure being useless.
Approximately 31% of the overall space is entirely unused throughout these five buildings.
When measured in genuine height, the Burj Khalifa stands at 584 metres, making it much less than the Makkah Royal Clock Tower in Saudi Arabia, which stands at 559 metres.
The Shard in London is just 20 percent occupied at this time.
The Empire State Building, which was completed in 1931, stood as the world’s tallest structure for more than four decades.
Timer for the construction of skyscrapers Since then, the pace of change has been swift.
The completion of the 452m-tall Petronas Towers in Kuala Lumpur in 1998 cemented the city’s position as the world’s tallest city — a position held until Taiwan’s Taipei 101 tower surpassed it in 2004.
With four towering structures in the Middle East and four in the United States (one of which is the new One World Trade Center), and 12 in Asia (including the twisting Shanghai Tower), the top 20 tallest structures are now distributed throughout the globe.
Worldwide, there will be over 16,000 of them by 2020, with a large number of additional ones on the way.
It is estimated that 329 construction projects are now underway in New York, which nevertheless boasts more skyscrapers than any other city (1,302!).
Hong Kong, on the other hand, appears to have run out of excitement – or available space: the city has just 50 additional skyscrapers under construction to add to the 806 already in place.
The projected H7 Shenzhen Tower would reach a height of 739 metres, whereas the Signature Tower Jakarta is expected to reach a height of 638 metres in Indonesia.
Planned developments in Dubai include the construction of what developers think would be the world’s highest twinned buildings as part of the Dubai Creek Harbour development.
The Jeddah Tower, a proposed skyscraper in Saudi Arabia, is by far the largest and most ambitious skyscraper project in the world.
By the time it is finished in 2020, it will be a full 1km in height. Follow Guardian Cities on Twitter and Facebook to participate in the conversation, and check out our collection of articles here.
