1 THE CHALLENGE FOR USING CIM IN CONSTRUCTION Hiroshi Furuya Obayashi Corporation

2 BENEFITS OF CIM The benefits of Construction Information Modelling (3D product model)

3 Benefits of CIM (Construction Information Management) Compared the two-dimensional CAD and 3D product model Two-dimensional drawings : If civil engineer look the data(drawings), he recognize and imagine the object. However, two-dimensional CAD is, mere "line", "curves and circle", a collection of "character", "pattern data". It s difficult to recognize the members to the computer. For 3D product model, based on object-oriented technology to represent a member shape and attribute data in a text file that is compatible. As a result, the data of 3D product model, the computer can understand. 3

5 SAMPLE USAGE OF THE ACTUAL CONSTRUCTION

6 Water resources utilization facility The structure information such as to be buried using the aggregation maintains the 3D model. In conjunction with local sensors (such as an IC tag), the behavior can be easy to understand. Inspection and maintenance history helps to update plan.

7 Tunnel construction Soil information Product model manage the observation information, the measurement information, and feedback in the 3D model. The model have implemented the centralized management of construction information. Since lining quality information such as concrete also saved and can be used as a maintenance model after completion.
