BIM’s information model of Railway made from existing 2D based drawings. Also, 3D model objects were linked with processes linkage. Adjacent to the construction site and construction of the line in the service of the managed BIM techniques with emphasis on three-dimensional virtual review system was constructed. Possible problems in advance of the main step-by-step review and constructability, and safety were examined.

By using the technique of BIM and observation data, We have developed a simulation system capable of real-time water management and hydrological analysis.

The study in advance about the potential risk that occurs torrential rain is able to create evacuation scenario in real time. Comparing 3D BIM with 2D based design:

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

Capacity for installation. Review of Safety Measure. Hydrological mathematical  analysis, the water level rise prediction system. Flood arrival provision system.
