World's Tallest Building

Skyscrapers are the buildings built with a super tall height. There seems to be much prestige in being home to the worlds tallest. So much in fact that this is a major issue on the political agenda of many countries. Many towers claim the title, and many cities quarrel about who is the winner. And the tallest building in the world were claimed by Burj Dubai (Dubai Tower).

Burj Dubai, Dubai, United Arab Emirates is the present tallest man-made building, which is under construction. The construction of this building began on 21st September 2004 and the construction is expected to be completed by the end of the year 2009. The height of the building is 818m, which is equal to 2,684 ft. The total budget of the Burj Dubai is about US $4.1 billion. This tower is composed of three elements arranged around a central core and it contains 26 terraces.

As the tower is residing in a flat desert base, setbacks occur at each element in an upward spiraling pattern to decrease the cross section of the tower as it reaches towards the sky.This dazzling building contains totally 162 floors. Notably the exterior cladding of this massive tower is of reflective glazing. The cladding is designed in such a manner that it can withstand even Dubai’s extreme summer temperatures. The 56 elevators with double-deck elevators will be installed. The speed of the elevators would be 700m/min.

The developers want the Burj Dubai to be world’s tallest building according to all four accepted criteria: structural top, highest occupied floor, top of the roof, tip of the spire/flagpole.

Burj Dubai will be opened on January 4th 2009 to coincide with the fourth anniversary of the accession to power by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai.

Oasis of the Seas : The world's biggest Cruise Ship

With length overall of 360m Oasis of the Seas is the largest cruise ship in the world, it almost 5 times longer than the largest airplane, Airbus A380, or 21m longer than once largest, The freedom of The seas.

With weight of 220,000 tons, the Oasis of the Seas is the world’s largest passenger vessel. It’s able to accommodate 6,300 passengers and 2,000 crew members on 16 decks. The floating giant was commissioned by Royal Caribbean International in 2006 and was finalized on October 29, 2009, in a Finnish shipyard.

The Oasis of the Seas left its birthplace and is now on route to Florida, in the USA, where it will receive thousands of exotic plants, before its commercial debut. The plants will decorate one of the ship’s seven neighborhoods, called Central Park. It will feature trees, lawns and flower beds.

Other attractions of the Oasis of the Seas include an ice rink, a water theme-park, a fairground carousel and a giant shopping area. Until next year, when her sister, the Allure of the Seas, will be completed, the Oasis of the Seas is the only ships in its class.

The Longest suspension bridge in the world: Su tong

The Sutong bridge over the Yang tze kiang (also known as Yangtze) has so many superlatives, here only some key data that is called because of its space is considered to be the longest cable in the world. Provides a passage of 62 m and is flanked by giant pylons. Together with the up and down during the more than 140 pillars of support and feed armors created to bridge the 8206 m Yang tze kiang here, depending on the season in some places up to 14 km wide may swell. And in order to anticipate it: the demand for concrete pumps concrete built here until its limit!

Before delivery of the high pressure pump concrete BSA 14000 HP-D Putzmeister had promised that the machine at 310 m by a pump head of 125 mm from other 30 m³ / h promotes. BSA were specific for pressures up to 260 bar. As in the 150 meters in the concrete pumping a disproportionate increase in hydraulic pressure was observed, switched parties in the Putzmeister AG, customer service and technical management in the project. After a slight change in the formulation of concrete, reinforcement of some very aggressive pumping of concrete and the use of components of carbide wear parts of the younger generation was able to promote high concrete continue.
The total cost of the Sutong bridge project is estimated at about 6.45 million yuan (about 726 million U.S. dollars), respectively. Work began in June 2003, completion is scheduled for 2009.
