BIM lightweight computer data processing and information sharing platform application

In order to solve the problem of lightweight processing of BIM model, the role of BIM technology in collaborative management and information interaction is studied and explored. Based on the self-developed BIM collaborative construction management platform, the lightweight processing technology of the super-mass BIM model is analyzed and studied, including the optimization of the geometric structure with parametric description, the rendering processing methods such as multiple LOD, batch drawing and occlusion and culling, etc., to optimize the loading of the platform model. Combined with the practical application of the case project, the EPC management methods such as progress, quality, safety and cost based on the BIM platform are provided. The experience summarized can provide reference for the lightweight processing of large-scale BIM models and the construction project management based on BIM.
