Before opening its 230,000 m² of shops, restaurants, cinemas and leisure centres, its spacious covered avenues and its parking lots and driveways, the Yas Mall was a 1.4 million m² building site. To produce its gigantic, multi-level concrete structure (378,000 m³), temporary openings had to be left in the floor decks for the huge tower cranes. On completion of work, these were extracted using 250 tonne mobile cranes.
