Super Skyscrapers

This four-part series follows the process of building four extraordinary skyscrapers that were built with the environment and safety in mind.  The architects provide behind-the-scenes information on such things as how their building was constructed to withstand a terrorist attack, what makes a skyscraper environmentally-friendly, what is involved in erecting a fast elevator, and how you clean 100th floor windows.
