Burj Khalifa – Skyscraper Supremacy – Big Bigger Biggest (Part 1)

Video Description

This super-skyscraper reaches nearly half a mile high into the clouds. Twice as tall as the Empire State Building, it is the tallest man-made structure standing on the Earth. The 160-story tower boasts 53 elevators, some capable of travelling over 20mph, a super-reflective glass skin that could cover 17 football fields, and a luxurious hotel designed by Giorgio Armani. Building this $1.5 billion superstructure consumed over half a million tons of concrete, twenty acres of glass and enough steel to stretch a quarter of the way around the globe. But the Burj Khalifa wasn’t built in a day. It stands on the shoulders of seven historic engineering achievements. We chart the stories of seven key inventions, embodied by seven landmark buildings that allow the Burj Khalifa to be so tall. 00:00 Introduction 02:28 Mobility – Equitable Life Building 10:01 Materials – Fuller / Flatiron Building 17:42 Heat – United Nations Headquarters 22:52 Speed – World Trade Center 31:43 Wind – Sears / Willis Tower 36:22 Earthquake – Taipei 101 43:43 Evacuation – Burj Dubai / Khalifa Episode from the “Big Bigger Biggest” documentary series exploring the engineering breakthroughs that have enabled us to develop some of the largest structures in existence.
