The development includes a vast five storey podium, five hotel towers, an underground theatre and an energy centre. Aurecon was involved in structural design services for the entire project, except for one of the hotels.
With a floor area of 188 000 square metres of three main levels that feature intermediate mezzanines, the hotels have a combined floor area of 230 000 square metres and provide 1 661 room in towers up to 36 floors high. The main structural grid is 8.4 square metres, although transfer beams or trusses are provided in areas such as ballrooms to give large, column-free spaces. Lateral stability is provided by reinforced concrete stair and lift core walls.
