Taipei 101, the world's tallest building, will be officially inaugurated in Taipei, Taiwan, on Dec. 31. The 1,666-foot skyscraper tops the previous record holder, the Petronas Towers in Kuala Lumpur, by 183 feet.

Designing the 101-story building in the earthquake- and typhoon-prone region presented quite a challenge. Engineers had to account for the fact that the tower stands about 650 feet from a major fault line, and that it will face winds of 100 mph.

Still, Taipei 101 won't hold the title of world's tallest skyscraper for long. Buildings in Shanghai and Dubai are expected to surpass it, as will the Freedom Tower in New York — on the World Trade Center site — which is scheduled for completion in 2009.

NPR's Melissa Block discusses the engineering know-how behind Taipei 101 with structural engineering consultant Dennis Poon of the Thornton-Tomasetti Group.
