Tallest Man made structure on the Earth…

KVLY-TV mast, USA : Tallest Man made structure on the Earth
The KVLY-TV mast (formerly the KTHI-TV mast) is a television transmitting mast in Trail County, North Dakota, USA, used by Fargo station KVLY channel 11. At 2,063 ft (628.8 m), it is currently the world’s tallest supported structure on land.

The tower is located three miles west of Blanchard, North Dakota, which is roughly halfway between Fargo and Grand Forks. It became the tallest artificial structure upon the completion of its construction on August 13, 1963. The mast was surpassed in height by 18 m (57 ft) in 1974 by the Warszawa radio mast near Konstantynów, Poland, but the latter collapsed on August 8, 1991, making the KVLY mast again the tallest structure on land. If completed as planned, the UAE’s Burj Dubai, presently slated for completion in 2008, will surpass the mast as the tallest land structure.
The tower was built by Hamilton Directors and Kline Iron and Steel, and took thirty days to complete, at a cost of US$500,000 ($3.3 million in 2007 dollars).
Owned by the Meyer Broadcasting Company (now North Dakota Television, LLC) of Bismarck, the tower broadcasts at 316 kW for television station KVLY (channel 11, an NBC affiliate) which is based in Fargo. The tower provides a broadcast area of roughly 30,000 square miles (78,000 km²).
Its overall height above mean sea level is 926 m (3,038 ft). Some time after its completion, the Federal Aviation Administration imposed a limit of 2,063 ft, based on this tower’s height, on future construction; consequently, no taller structures may legally be built in the U.S. at present.
The call letters of the television station for which it was built were originally KTHI, the “HI” referring to the height of the mast. The top is reachable by service elevator or ladder.

RIPPED FROM WIDIPEDIA!!!!

Burj Dubai (Arabicبرج دبي‎ “Dubai Tower”) is a supertall skyscraper under construction in DubaiUnited 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 builder is South KoreanSamsung Engineering & Construction, who also built the Taipei 101 and Petronas Twin Towers.[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]
