Skyscrapers: Engineering the Future

Skyscrapers have dominated city landscapes for more than 100 years. Since debuting as 10-story buildings in the late 19th century, these tall towers have constantly evolved as architects and structural engineers pushed the boundaries of what's possible. This series unlocks the inner workings of these goliaths, spotlighting what cities such as Chicago, London, Melbourne and Tokyo are doing to transform their skylines with designs that seem to defy gravity. Each episode gives viewers exclusive looks at high-rises, among them Chicago's 82-story Aqua; the 1,500-feet-tall Petronas Twin Towers in Kuala Lumpur; the landmark Jin Mao Tower in Shanghai; and the Burj Khalifa in Dubai, the world's tallest skyscraper.
