In this project, the curved surface of heavy bamboo ceiling is parallel to that of metal roof panel, both of which are in hyperbolic shapes with various curvature changes. The traditional 2D deepening design method fails to complete the analysis of double curved bamboo ceiling, let alone to achieve the need of preparing reasonable construction scheme and precise material cutting and processing. The project adopts 3D spatial BIM modeling to implement the layout and vector height analysis of each plate of the whole surface. According to the deformation performance of materials, the BIM model contributes to the selection of best installation method and composite collision detection, which problems such as error accumulation, collision, demolition or installation failure in subsequent construction. The design effect is well guaranteed, and the project cost is saved.
