Abstract: Currently subway project are rapidly developing in China. Many cities have subway construction demand. Large cost and tight schedule are the characteristics of subway engineering. Cost and schedule combined optimization is very necessary. In addition BIM technology has been widely researched and applied in engineering. But in the subway project, BIM is mainly used in modeling, collision checking, construction simulation etc. and the application in other areas is less. The application of aspects is often independent. In this paper, 3D + schedule + cost of construction management application is made based on BIM technology and earned value management method. For the subway station project, schedule and cost tracking are carried out. This paper has extended the application of BIM technology in the subway project.

Key words: building information modeling technology, subway engineering, earned value method; construction management
