With the upgrading of building industry, intelligent construction and intelligent operation and maintenance, it has been a trend to deepen the application of BIM technology in construction projects. Taking the large-scale industrial park project as the research object, this paper gets rid of the difficulty of positioning and integrating the group project model by using the method of shared coordinates in BIM software. In the aspect of deepening mechanical and electrical pipelines, the visual programming software Dynamo plug-in is used to realize the color filling of different beam heights with one-key operation according to the complex characteristics of basement elevation changes. What's more, the clearance under the beam is intelligently analyzed, so as to provide a basis for the comprehensive layout of electromechanical pipelines. The research results can provide reference for similar projects.
