About the Taipei 101 Tower
The design of Taipei 101 borrows heavily from Chinese culture. Both the building's interior and exterior incorporate the Chinese pagoda form and the shape of bamboo flowers. The lucky number eight, which means blooming or success, is represented by the eight clearly delineated exterior sections of the building.

About the Shanghai World Financial Centre
The Shanghai World Financial Centre, or Center, is a soaring glass skyscraper with a distinctive opening at the top. The original plans called for a 46 meter (151 foot) circular opening that would reduce wind pressure and also suggest Chinese symbolism for the moon. Many people protested that the design resembled the rising sun on the Japanese flag. Eventually the opening was changed from circular to a trapezoid shape.
The ground floor of Shanghai World Financial Centre is a shopping mall and an elevator lobby with gyrating kaleidoscopes on the ceiling. On the upper floors are offices, conference rooms, hotel rooms, and observation decks.

About the Petronas Towers
Traditional Islamic design inspired the floor plans for two Petronas towers in Kuala Lumur, Malaysia. Each floor of the 88-story towers is shaped like an 8-pointed star. The two towers have been called cosmic pillars that spiral heavenward. At the 42nd floor, a flexible bridge connects the two Petronas Towers.

About the Sears Tower
To provide stability against high winds, architect Bruce Graham used a new form of tubular construction for Sears Tower. Two hundred sets of bundled tubes were laid into the bedrock. Then, 76,000 tons of prefabricated steel in 15-foot by 25-foot sections were put into place. Four derrick cranes moved higher with each floor to lift these steel "Christmas Trees" into position.
Facts about the Sears Tower:
* The Sears Tower covers two city blocks and has 101 acres (4.4 million square feet) of office and commercial space.
* The roof rises a quarter of a mile -- 1, 454 feet (442 meters).
* Its highest occupied floor is 1,431 feet above the ground.
* The foundation and the floor slabs have some 2 million cubic feet of concrete -- enough to build an eight-lane highway five miles long.
* The Tower has more than 16,000 bronze-tinted windows and 28 acres of black duranodic aluminum skin.
* The 222,500-ton building is supported by 114 rock caissons. Each is securely socketed into the bedrock.
* A 106-cab elevator system (including 16 double decker elevators) divides the Tower into three separate zones, with skylobbies in between.
