Photo taken by me in 2006, whilst living in Dubai. The building of the tallest man-made construction in the world, nowadays standing at over 800 meters as a 163 storey skyscraper, was on its way and the typical shape was already noticeable. The building, originally called Burj Dubai, was at completion in 2009 renamed Burj Khalifa (Burj meaning tower). As a global icon, designed by Chicago based architecture firm and built by over 30 on-site contracting companies and 12,000 workers from over 100 countries (mainly from South- & East Asia), this building project was truly global in nature. In the end, Burj Khalifa's construction had used 330,000 m3 of concrete and 39,000 tonnes (43,000 ST; 38,000 LT) of steel rebar, and construction had taken 22 million man-hours. In addition to concrete and steel, other major materials used are glass, silicone, and aluminum, which make up the outside façade of the tower. No doubt with the volumes needed that raw materials were sourced abroad, most likely glass from Asia and steel a.o. from India. However, i can't find any information on this topic. I assume there has been on-site production of concrete, with raw materials expectedly sourced inland and from neighbouring countries.
