The foundation used in this hotel is Pile Foundation and a total of 230 – 40 meter long concrete piles were drived into the sand. The foundation is held in place not by bedrock, but by the friction of the sand and silt along the length of the piles. Engineers created a surface layer of large rocks, which is circled with a concrete honey-comb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, but less than three years to construct the building itself. The building contains over 70,000 cubic meters of concrete and 9,000 tons of steel.
