As an important part of building industry transformation upgrade, BIM technology was used widely in large complicated project.The subway station project is characterized by huge quantity, complex pipeline systems, and difficult equipment installation.This paper introduces the concrete application in three phases like design phase, construction phase and maintenance phase.BIM technology was introduced into the project all-around, which help build the subway station all professional model to realize the professional 3D visualization and make organic connection of each professional flat vertical profile control drawing information is established.Collisions inspection among different professions, the virtual simulation and 4D virtual construction technologies will improve the working efficiency and save the project cost.BIM technology in the application of subway station project can help promote BIM technology to widely use in complicated engineering project and play a reference.
