aesung S&I made a BIM based design from existing 2D based design about the railway station and associated tunnel. The purposes of this project are as follows.

3D Station Modeling on the structures and steelworks:

Review of Construction Sequence b/w structural works and earthworks. Estimation of

Construction Materials. Comparing BIM with 2D based drawings. Crash Detective between Structures.

3D BIM’s information model was used to check the construction sequence of tunnel and railway station considering the processes linkages. And exact amount of materials was derived from 3D BIM.
