Base system is developed in CIM guidelines. Drilling mountain tunnel construction and placing lining concrete is collected in CIM data. At drilling stage, visualization was achieved by importing data, and by converting "A measurement data" into 4D. After construction of shotcrete and placing of lining concrete, we perform 3D measurement by MMS. By using CIM, we can do the following 1.Securing cross-section design 2.Calculating volume of concrete lining, 3.Checking support and bolts, 4. Checking lining concrete thickness. Finally, we realize efficiency and sophistication of construction.
