The highlight of this project is that the extremely difficult technology,and uses GRG(GlassFiber Reinforced Gypsum)materials for design,as well as uses the pre-cast processing technology to customize the hyperboloid shape.Each surface needs to be modeled on the computer first,customized production in the factory,and assembly on site.During installation,because the three-axis coordinates of each point of the modeling surface are changing,the position of each plate must be very accurate,which is also the technical difficulty of the project.
