At 228 meters, the 54-storey Grand Lisboa is one of the tallest buildings in Macau. Inspired by the shape of a lotus flower, the upper part of the structure cantilevers to over 20 meters on each side. The podium entertainment area is covered by a large elliptical sphere that has a thin shell structure braced by a skeletal design, allowing unrestricted views. Using our structural expertise, we developed a solution that fulfilled the designers’ vision and also satisfied the seismic design requirements of Macau’s building code.
