Burj khalifa, Did You Know

Burj Khalifa, do you know what it took to build the worlds tallest free standing building?

Burj Khalifa

Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation, which features 192 piles buried more than 50 m (164 ft) deep. Burj Khalifa’s construction will have used 330,000 m3 (431,600 cu yd) of concrete and 39,000 tonnes (43,000 ST; 38,000 LT) of steel rebar, and construction will have taken 22 million man-hours.

Exterior cladding of Burj Khalifa began in May 2007 and was completed in September 2009. The vast project involved more than 380 skilled engineers and on-site technicians. At the initial stage of installation, the team progressed at the rate of about 20 to 30 panels per day and eventually achieved as many as 175 panels per day.

The tower accomplished a world record for the highest installation of an aluminium and glass façade, at a height of 512 metres. The total weight of aluminium used on Burj Khalifa is equivalent to that of five A380 aircraft and the total length of stainless steel bull nose fins is 293 times the height of Eiffel Tower in Paris.

In November, 2007, the highest reinforced concrete corewalls were pumped using 80 MPa concrete from ground level; a vertical height of 601 metres. Smashing the previous pumping record on a building of 470m on the Taipei 101; the world’s second tallest tower and the previous world record for vertical pumping of 532 metres for an extension to the Riva del Garda Hydroelectric Power Plant in 1994. The concrete pressure during pumping to this level was nearly 200 bars.

The amount of rebar used for the tower is 31,400 metric tons – laid end to end this would extend over a quarter of the way around the world.

Ferrari World Abu Dhabi, Did You Know?

Ferrari-world-abu-dhabi

Ferrari World Abu Dhabi Facts:

  • The 86,000 m2, enclosed area of Ferrari World, can fit 7 football fields in ‘head to toe’.
  • The total roof area of 200,000 m2 uses enough aluminum to cover 16,750 Ferrari’s, or if you laid the roof flat you could place 20,100 Ferrari’s side by side and end to end.
  • If Ferrari World was turned upright, it would be the tallest man made structure in the world at over 300 floors!
  • The Ferrari logo on the roof, the largest ever created, measures an incredible 65m in length and covers an area of 3,000 m2 which could fit at least 7 basketball courts.
  • The volume of concrete in Hoover Dam could fit inside Ferrari World.
  • 100,000 m3 of concrete was used to pour the slabs of Ferrari World, which is 10,000 m3 more than what was used for Wembley Stadium in London.
  • Ferrari World has the largest space frame structure ever built with a total of approximately 172,000 members and 43,100 nodes.
  • Ferrari World needed 12,370 tons of steel to create its structure; the Eiffel Tower only needed 7,000 tons.
  • The gross footprint area of the plaza level is equivalent to approximately 15 American Football fields.
  • The Empire State Building could be rebuilt in the same time it took to clad the 200,000 m2 of roof for Ferrari World Abu Dhabi; approximately 14 months.
  • Formula Rossa, the world’s fastest roller coaster, has the same G force one would feel driving in an F1 car and braking at maximum speed.
  • Ferrari World includes 1,200 dining seats – enough to feed the entire park at full capacity in 3 hours.
  • Ferrari World Abu Dhabi is the world’s only venue to house Four Michelin-star experienced Italian chefs under one roof.
  • A football field needs 8,400 m2 of grass coverage; to cover the area around the roller coasters at Ferrari World, 4.5 times that amount was used – approximately 39,000 m2 of ground cover.

Eiffel Tower, Did You Know?

Eiffel Tower

It’s 126 years since the famous Iron Lady was inaugurated in time for the 1889 World Fair in Paris.

It is now one of  the most visited monuments in the world and around seven million people climb its stairs or take the lift to one of its three levels each year.

But it’s worth remembering that it was not always this popular. When construction began in July 1887, a group of around 300 artists, sculptors and architects sent a petition to the commissioner of the Paris exhibition demanding that he halt construction of the “ridiculous tower”.

Here are 12 facts about the Eiffel Tower:

1. Two years, two months and five days – That’s how long it took to build the Eiffel Tower, with construction beginning in 1887.

2. 7,799,401.31 – That’s what it cost in French gold Francs to build the monument.

3. 324 metres – That’s the height of the Eiffel Tower, including the antenna at the top. That works out at 1,063 feet. Without the antenna it is 300 metres tall (984 feet).

4. Six inches – That’s how much the tower grows in the sun. Yes the Eiffel Tower grows when it gets hot and shrinks in the cold. Although this is fairly hard to see with the naked eye.

5. 10,000 tonnes – That’s how much the Iron Lady weighs.

6. 20 years – That’s how long the Eiffel Tower was originally designed to last. It was built by Gustave Eiffel to commemorate the French Revolution and show off France’s industrial might. The removal men were meant to pull it down after 20 years, but Eiffel appears to have persuaded them to have a change of heart. The fact that the tower could be used as a wireless telegraph transmitter, made it fairly useful and saved it from the wrecking ball.

7. 103,000 kilometres – That’s the distance one lift travels each year, according the site livescience.com, which, to put into perspective is two and a half times the circumference of the earth. There are steps up to the top – 1,710 of them – but visitors can only walk up to the first floor.

8. 18 – That’s the number of times the iron lady has been repainted over the years. It takes a mammoth 60 tonnes of paint to give it a first coat. 

9.  41 years – That’s how long the Eiffel Tower was the world’s tallest building for, before the Chrysler Building in New York came along and stole its mantle.

10. 250 million – That’s the number of people who have paid a visit to the Eiffel Tower over the years. 

11. 1944 – The year when the Eiffel Tower could have been pulled down. Hitler ordered the German military governor of France to tear it down but he refused.

12. Six to seven metres – This is the amount the Eiffel Tower sways in the wind.
