Building on Sand—Structural Design of Dubai's Burj Khalifa

One curiosity about the Burj Khalifa is that 35,000 tonnes of structural steel used in its construction came from the Palast der Republik in Berlin, the former home of the East German “parliament”. After German reunification, the building was condemned and demolished for health reasons, as it contained more then 5000 tonnes of asbestos. The steel was salvaged and eventually shipped to Dubai for use in the skyscraper.
