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 Because of needing in-depth study for safety and workability in the construction section of the high degree of difficulties to cross the road and the existing railway, the construction site, the potential to build a 3d virtual evaluation system by the method of BIM the study problem in advance, construction of the main step-by-step and safety considerations:

Completion of detailed Construction Time Schedule. Review of 3D model objects and processes linkages. Review of Safety Measure. /Proper Estimation of Equipment 
Capacity for installation. Comparing 3D BIM with 2D based design.

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.
