Abstract: Wudongde Hydropower Station BIM design model is based on the 3D collaborative design platform of CATIA, which integrates with design-check-review (DCR) process management and BIM standard system.The BIM design model involves multi-major, such as digital survey and geology, hydraulic engineering, bridge and tunnel, building, electromechanical, metal structure, construction and so on.During different phases of engineering survey and design, scheme comparison and demonstration, parametric design modeling, finite element analysis, collision detection, engineering automatic statistics, 3D rebar design, 2D drawing, construction simulation and visual performance are carried out based on the BIM design model.The 2D drawing problems from 3D geological model, hydraulic structure model and complex shaped structure 3D rebar design model have been focused and resolved.
