Abstract: In order to improve the design level and respond to national policy requirements,taking the forward construction drawing design process of a sewage treatment plant as an example,based on Revit software,a detailed comparative analysis was conducted on the selection of collaborative platforms,collaborative method planning,software and hardware requirements,view templates,equipment production,data security,and other preliminary preparations. Practice was conducted on how to proofread,provide information,synchronize structural data,and adjust the collision of management and integration during the design process. A forward design process suitable for underground sewage plants is summarized. It is proposed that problem-solving should be the core,and various conditions such as technology,manpower,resources,design cycle,and design fees should be fully considered. On the basis of current technological feasibility,it should be steadily promoted step by step without increasing too much resource investment and changing too many design management processes.

Key words: Building Information Model （BIM）, semi-underground sewage treatment plant, construction drawings, professional collaboration
