Abstract: Aiming at the problem that the information content of process equipment component library cannot meet the design and use requirements in the forward design process of Building Information Modeling (BIM) of metro depot, this paper proposed the basic flow and information flow optimization method of process design of metro depot by using BIM forward design technology, studied the method of multi-channel 3D modeling of process equipment and automatic input of information based on Revit platform in the field of process design. The results of this study can improve the efficiency of process design cooperation and provide reference for the process forward design basis of metro depot and other industrial plant construction projects.
