This is another proof that the engineering thought in the Arab world is developing with giant leaps. Essentially the building is a 160-meter tall skyscraper with 18-degree incline to the west - more than four times that of the world famous Leaning Tower of Pisa. It has therefore been certified as the world's furthest leaning manmade tower by Guinness World Records.
Standard skyscrapers are being built by rising concrete core in the center, around which the floors are built. In this case, to compensate for the slope of the building to the west, the core is tilted in the opposite direction and this provides structural stability of the building. The concrete core is built level after level, each concrete level is pierced by overlapping and highly tensioned steel ropes, which provides some flexibility to the building.
