The Tallest Buildings in the World

Dubbed The Worst Building in the History of Mankind by Esquire Magazine in January, 2008, the unfinished and never occupied 105-storey Ryugyong Hotel is reportedly back under construction after a 16-year lull.

The Ryugyong Hotel is an unfinished concrete skyscraper. It was intended for use as a hotel in Sojang-dong, in the Potong-gang District of Pyongyang, North Korea. Its 105 stories rise to a height of 330 m (1,083 ft), and it contains 360,000 m² (3.9 million square feet) of floor space, making it the most prominent feature of the city’s skyline and by far the largest structure in the country. At one time, it would have been the world’s tallest hotel.

The new tower proposed to be built in the City of Silk in Kuwait is planned to be 1001 meters high.

The Al Hamra tower upon completion will cover 22,000 square metres and reach 412 metres in height, making it the tallest building in Kuwait. It will overtake the nearby Liberation Tower, the current tallest building which stands at an altitude of 372 metres.

Moreover, Suhail added that the size of the tower would equal the combined size of the five biggest office towers in Kuwait.

Al Hamra Tower will also be the tallest ’sculptured’ tower in the world as well as the tallest stone-clad skyscraper.

Regarding the tower’s design, whereas almost all skyscrapers are symmetrical over their main axis. Al-Hamra Tower has two tilting walls, one on each side, moving up in the air more than 50 metres away from their original location to almost 350 metres in height.

About 195,000 cubic metres of concrete, 6,000 tons of metal structures and 38,000 tons of iron will be used in building the tower, which will be installed with 40 elevators, some of which will run at speeds of up to 10 metres per second with a payload of up to 40 people.

Furthermore, there will two service elevators with a payload of up to seven tons. The complex will contain a 77-storey tower; each floor will contain only three offices. Each floor covers an area of approximately 2,400 square metres.

As many as 290 piles with a capacity of 1,200 tons each were put in the foundation. Concrete mix design was developed by the contractor specifically for the job as it is the first time that concrete strength above 600kg/m2 has been used.

The special mix took a lengthy research in the company’s laboratories, as the constituents available in Kuwait were not adequate for this high performance, and they succeeded in reaching on site strength of 1000kg/m2.

Seoul and other major cities across the nation will see a new skyline as the construction of 12 skyscrapers with over 100 stories is underway.

These buildings will stand at least 400 meters high, according to the Ministry of Land, Transport and Maritime Affairs.

Seoul alone will have six skyscrapers, including Dream Tower, with 152 stories at a height of 620 meters in Yongsan, and the second Lotte World building in Jamsil. In the nation’s largest port city, Busan, four skyscrapers will be constructed, including Busan Lotte World, 120 and 510 meters high.

Korea is expected to outrun other nations in terms of number of skyscrapers with over 100 stories if all these towers are completed. Currently, the United Arab Emirates has six skyscrapers of a similar scale, followed by the United States with four and China with one.

Such constructions are expected to become a landmark and serve as a new source of tourism and regional economic growth. The existence of such high buildings also helps its neighborhood become better developed.

Some are concerned they may be hazardous in the face of natural or human disasters such as earthquakes and fire.

“We have basic guidelines for the construction of skyscrapers, which consider the city’s overall appearance and safety,'’ an official from the Seoul City Government said.

Another problem might be financing the construction.

The construction of buildings with more than 50 stories requires approximately twice the budget as those with fewer than 50. They also require high-tech methods of construction with the combination of various industries.

Consequently, projects for the construction of skyscrapers face difficulties in finding business partners or forming consortiums.

Some of the projects are pending due to finance issues, such as the construction of a skyscraper in Junggu, downtown Seoul, and a tour resort complex in Haeundae, Busan.

The race to build the world’s tallest building has reached a new level with plans for a mile-high tower to be built near the Red Sea port of Jeddah in Saudi Arabia.

The multi-billionaire owner of the Savoy Hotel in London has unveiled plans for the ambitious £5 billion tower, which will overtake skyscrapers planned or under construction in Kuwait and Dubai.

The Mile High Tower will be double the height of its nearest rival and visitors will be able to see Africa from the top of the tower.

Riyadh-based Kingdom Holding, which is controlled by billionaire Prince al-Walid bin Talal, will invite bids before July for contracts to build the tower in Saudi Arabia’s commercial capital. It is estimated the project will cost approximately 5 billion pounds. The project will push architecture and engineering to new limits, as the tower must be robust enough to withstand the extremes of temperature and strong desert winds in the region. Masterminded by British-based engineers, the building will be onstructed in a “mini-city” near the Red Sea port of Jeddah and ould be twice the height of the world’s tallest building.

The 51-year-old’s Kingdom Holdings has appointed a joint venture et up by Hyder Consulting and Arup, the London enginerring irms, to build the 5 billion pounds tower.

The building will be fitted with a giant computer-operated damper tretching down several floors - to counter the nausea-inducing way caused by the wind.

The structure will also be stabilized by two mini-towers, lanking the building’s base and attached to the main structure y arched sky-bridges.

The world’s tallest skyscraper under construction in the Persian Gulf city-state of Dubai will take longer than planned to finish, its builders said, putting off the opening planned for the end of this year.

The Burj Dubai tower currently stands over 1,700 feet tall. The state-owned developer Emaar Properties said completion would be postponed until sometime in 2009. It did not give specifics, but the newspaper Gulf News and the online news site ArabianBusiness.com said the delay would be four months.

“The company would rather opt for a nominal delay in total quality execution of the Burj Dubai … than compromise on any aspect of quality,” Emaar, one of the main builders in this Gulf boomtown, said in a press release without elaborating.

Emaar did not give the reason for the delay.

The final height of Burj Dubai is a closely guarded secret. Emaar’s representatives previously said the tower will stop somewhere above 2,275 feet.

Last summer, the company said the skyscraper had reached 1,680 feet, surpassing Taiwan’s Taipei 101 which has dominated the global skyline at 1,667 feet since 2004.

When completed, the Burj Dubai will have more than 160 floors, 56 elevators, luxury apartments, boutiques, swimming pools, spas, exclusive corporate suites, Italian fashion designer Giorgio Armani’s first hotel, and a 124th floor observation platform.

Two days ago, the all-authoritative Xinhua produly proclaimed that the new building, which is to be named Shanghai Center (we are unsure if this has any relation to the existing Shanghai Center) will be the tallest building east of Dubai at 580 meters and 118 stories. According to them, that’s 72 meters higher than the Taipei 101 Tower, currently the tallest building in Asia at 508 meters.

Bangalore is all set to have the world’s tallest sky tower at Tippasandra near BDA’s Anjanapura Layout. The proposed tower will scale 560 metres, beating the Canadian National Tower (553 metres) in Toronto.

The sky tower was earlier planned in Freedom Park on the old Central Jail premises, but was scrapped because it would have attracted a lot of tourists, leading to traffic problems.

The proposed tower will be built to boost communications, tourism and commercial activities. It will be a major landmark in the southern part of the city.

A special feature of the tower is that it will be a major revenue earner for the BBMP. With a microwave dish platform at an altitude of 410 metres, the tower will enhance overseas and inter-departmental communications of government organizations like the Railways, All India Radio (AIR), police and Doordarshan.

Four floors will be earmarked for these organizations.

This apart, four floors will be set aside for private telecom giants, who will set up their infrastructure.

The floor diameter at 350 metres serves as a microwave disc platform to facilitate live telecast of major events within a radius of 100 km. Visitors can get a bird’s eye view of Bangalore from here.

Created by Skidmore Owings & Merrill (the same group behind New York City’s Freedom Tower), it will be a zero-energy building — and thanks to its massive array of solar panels up top actually feed back to the grid. Everything from air-conditioning to heating to lighting will be covered by clean, green energy — enough to cover the needs of the 5,000 people expected to work there.

“It’s unique cooling system will take cold water from the river Seine and pump it around the building - eliminating the need for a traditional air conditioner. The building will also utilize cutting edge insulation, reducing amount of electricity consumption per square meter of office space per year to 16 kilowatts, the lowest in the world for a building of its size.”

Cost are expected to be about 25%-30% above that of a comparable old school office structure.
