BIM’s information model of Railway made from existing 2D based drawings. Also, 3D model objects were linked with processes linkage.
The review of the potential problems in advance by constructing a 3d virtual evaluation system by the method of BIM, construction of the main step-by-step and safety considerations. Review of a 3d simulation which is reflected on the process by stage construction of high-speed line, Honam line and temporary line:

Review of 3D model objects and processes linkages. Proper Estimation of Equipment

Capacity for installation. Review of Safety Measure. 3D Equipment Library System.

3D BIM was used to check the safety measure considering the processes linkages and make the detailed construction time schedule. Also, proper equipment capacity was estimated from 3D BIM equipment simulation.
