What is the tellest man-made structure in the world?

Answer 1

The tallest man-made structure in the world is The Burj Dubai in the Dubai, United Arab Emirates. It is still under contruction, but when finished, it will be 2,684 ft. tall. But the tallest man-made strucute that is completely finished is the Taipei 101. It is 1,671 feet in height.

Answer 2

Burj Dubai (Arabic: برج دبي‎ "Dubai Tower") is a supertall skyscraper under construction in Dubai, United Arab Emirates, and is the tallest man-made structure ever built, at 818 m (2,684 ft). Construction began on 21 September 2004, and the tower is expected to be completed and ready for occupancy on 4 January 2010.[1][2]

The building is part of the 2 km2 (0.8 sq mi) flagship development called "Downtown Burj Dubai" at the "First Interchange" along Sheikh Zayed Road, near Dubai's main business district. The tower's architect is Adrian Smith, who worked with Skidmore, Owings and Merrill (SOM) until 2006.[6][7] The Chicago-based architecture and engineering firm SOM is in charge of the project.[6] The primary builders are Samsung Engineering & Construction and Besix along with Arabtec.[8] Turner Construction Company was chosen as the construction manager.[9]

The total budget for the Burj Dubai project is about US$4.1 billion, and for the entire new "Downtown Dubai", US$20 billion.[10] Mohamed Ali Alabbar, the CEO of Emaar Properties, speaking at the Council on Tall Buildings and Urban Habitat 8th World Congress, said that the price of office space at Burj Dubai had reached US$4,000 per sq ft (over US$43,000 per m2) and that the Armani Residences, also in Burj Dubai, were selling for US$3,500 per sq ft (over US$37,500 per m2).[11]

Answer 3

The Banaue Rice Terraces is the largest man made structure since if you put it from end to end it would stretch out half the world's orbit (ten times longer than the Great Wall of China) and if put on top of the other would be the highest including the tallest building ever made.

Answer 4

The Great Wall of China was said to be the only man-made structure on earth visible from space. However astronauts have tried to see it and failed. If you go on Google Earth or similar you can try to find it from an altitude of 100km (the official "edge of space"). The problem is not the length, but the width of the wall. Its narrowness makes it invisible.

At night, lights from major cities may be visible. Cities would count as a man-made structure. During the day, cities and airports are visible from low Earth orbit.

At a distance of several thousand miles, only clouds, continents, ice caps, and major bodies of water are visible (weather permitting). Nothing man-made except the lights of cities can be seen from the Moon.

A recent addition to the "visible from space" collection of Earthly objects are the Athabasca Oil Sands projects in Alberta Canada. These are vast open pit mines which allow the removal of sands saturated with heavy bitumen for oil recovery.

Answer 5

The great wall of China is the largest artificial structure on earth that can be seen from space.

Ah, I'm afraid its visibility from space is a modern myth, unless you count Google photographs. Many astronauts have looked hard at China and say it is not visible. After all, although it's very long, it's only a few metres wide.

Answer 6

The Great Wall of China is the largest man-made structure in the world; it is visible from space, and has been photographed from space.

Answer 7

the china wall.
