Explorers:
Golden Gate Bridge, San Francisco.



Each of the bridge's two main cables is made of 27,572 strands of wire.

Often referred to as "the bridge that couldn't be built,".

The Golden Gate Bridge crosses the stretch of water nicknamed "the Golden Gate" by gold prospectors heading to the Californian hills.

Prior to 1937, San Francisco was America's largest city but its growth rate was slow compared to others, due to the lack of a link with other communities around the bay.

The size of the strait (2,042 meters wide) combined with strong winds and regular earthquakes led many construction experts to say a bridge couldn't be built.

The solution?

Huge amounts of concrete, 128,747 kilometers (80,000 miles) of wire housed inside two cables, 600,000 rivets and a whole lot of hard work.

Completion date: May27, 1937.

Explorers:
Kansai International Airport, Osaka, Japan.



Kansai International Airport was the first airport to be built on an artificial island.

Osaka is one of Japan's most crowded cities, so when a new airport was called for, engineers came up with a novel solution , a man-made island.

Construction of the island, which measures four kilometers (2.5 miles) by 2.5 kilometers (1.6 miles) took three years.

Some 10,000 workers and 80 ships were used to excavate 21 million cubic meters of landfill and the island's construction became the world's most expensive civil engineering project, with a total cost of$20 billion.

Completion date: 1994.

This remains one of the mysteries of the Ancient world. Billyonaire came up with a theory that it was contracted by gods or something

Tobitrueman:


A beg help me with that Billyonaire's thread about the pyramid

Explorers:
Colosseum, Rome.



The Colosseum could accommodate 50,000 spectators.

It's the largest amphitheater built by the Roman empire.

It's estimated that the outerwall, which is 189 meters long and 156 meters wide, was originally built using 100,000 cubic meters of travertine stone.

Some of this stone was later used in the construction of St Peter's Basilica and other nearby monuments.

Completion date: 80 AD.

Nice post but can you explain more on the quoted. Thanks.

Explorers:
Eiffel Tower, Paris.



Temperature alters the height of the Eiffel Tower by up to 6 inches (15 centimeters) over the year.

The Eiffel Tower weighs 13, 200 tons and was the first building to surpass the height of the Great Pyramid of Giza at 324 m (1,063 ft).

It remained the world's tallest building until 1929, when New York's Chrysler Building took the top spot.

Gustave Eiffel's initial building plans and calculations were so precise that no revisions had to be made during the construction process.

Completion date:March 31, 1889.

Explorers:
Burj Khalifa, Dubai, UAE.

The Burj Khalifa has a height of 828 meters and is both the tallest building in the world and the tallest free-standing structure in the world.

Engineers faced multiple challenges, including the strong winds that batter the tower.

Because of this, over 40 wind tunnel tests were conducted, not just to determine how the wind would affect the building but also to test the cranes used to construct it.

Completion date: January 4, 2010.

Explorers:
From the Great Pyramid built almost 3000 years ago with over 2million stones weighing 2.5 tons each to the Palm Islands in Dubai, built of islands that had to be constructed from rock and sandstone, to stepping out onto an oval glass ring above the Grand Canyon.

These are just a couple of amazing constructions found around the world and here are some of the greatest feats of engineering that we think are worth a mention.

Dyt come and carry me go Dubai

Dyt:

Why not if not All we need for a week is just $5k

Funjosh:



You know I dont spend $ again, we roll in #

Temitoppe:
this San Francisco why is it being choose to depicts devasted place in Hollywood movies??

talk of Robot(will smith), pixels, San andreas, dawn of planet of apes etc.

Twizzy30:
Explorers. I also hrd of a hotel somewhere in asia which has pool in every floor. Have u seen it bfor?

Explorers:
International Space Station.



The International Space Station cost $100 billion to build and involved 100,000 people in 15 nations.

It also ranks as one of the more unusual construction sites, located 354 kilometers (220miles) above Earth.

The hazards faced by those carrying out maintenance go far beyond a falling hammer or nail gun injury one tiny rip in a protective spacesuit means instant death.

Completion date: Ongoing.
