Burj Khalifa – the tallest building in the world
Burj Khalifa tower is the tallest building in the world, according to Guiness Book of Records. The building is located in Dubai, United Arab Emirates. It is 828 m (2,716 ft 6 in) tall. The Burj is more than twice the height of the Empire State Building, and almost three times the size of the Eiffel Tower.
In the course of confirming the Burj as the World’s tallest building, Guinness World Records also ratified a number of other lofty achievements for the ground-breaking structure.
To name a few, it has the Tallest elevator in a building (504 m; 1,654 ft), can boast the Most floors in a building (163) and the Highest restaurant from ground level (441.3 m; 1,447 ft 10 in).
Road to becoming the tallest building
In March 1996 the Petronas Towers in Kuala Lumpur, Malaysia, overtook the Sears Tower’s record as the world’s Tallest office building. Stainless steel pinnacles 73.5 metres (241 ft) long placed atop the 88-storey towers brought their height to 451.9 metres (1,482 ft 8 in).
Then, in 2003, Taiwan’s Taipei 101 (also known as the Taipei Financial Centre) took the title at a huge 508 metres (1,666 ft). Just one year later, construction on the Burj Khalifa began.
It was to form part of a new 2 km2 (490-acre) flagship development called Downtown Dubai at the ‘First Interchange’, near Dubai’s main business district in the UAE.
The towering property was developed by Emaar Properties and the architects Skidmore, Owings & Merrill LLP, headed up by renowned American architect, Adrian Smith.
Reaching a breath-taking 828 m (2,716 ft 6 in) into the sky, this new skyscraper would soon be described as a ‘vertical city’ and become an icon of the modern world.
All over the globe, people were asking whether it was even possible to construct a building that high – and that was when the Burj was designed to be ‘just’ 518 metres tall, 10 metres taller than the Taipei.
It actually grew by a whopping 310 metres during the design process – aproximately the height of the Eiffel Tower in France.
Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009.
The taller a building is the greater the effects of weather, but the neo-Futurist-style Burj Khalifa was designed with a complex Y-shaped cross section to reduce the effect of wind.
Everything about the Burj is superlative and involves huge numbers: there were more than 12,000 people from all over the world who worked on the construction of the Burj Khalifa.
Almost 26,000 hand-cut glass panels were used in the exterior cladding of the building, which has residential, office and hotel use. It takes about three months to clean the structre from the top to the bottom!
The individual stalks that rise out around the central spire deflect most wind around the building. Chief structural engineer Bill Baker calls it ‘confusing the wind’.
The monumental edifice officially opened on 4 January 2010 and was certified as the Tallest building on the planet.
“It’s a very impressive building with a very unique design,” said Talal Omar, Country Manager of UAE, Guinness World Records, on announcing the record.
