In construction of the 3 layers welded spherical grid structure of the large roof of Shenzhen Citizen Center, engineers assembled as many steel balls and pipes as possible to form open quadrangular pyramids and close quadrangular pyramids. The welded spherical grid structures from area 1 to area 5 were assembled at low level, and then lifted entirely two times to the design height. Engineers adopted two lifting methods, apart and block by block, to lift the welded spherical grid structures of area 6 and area 7.
