Abstract
As for the use of the 3D product model about the civil engineering field, popularization was begun by the CIM(Construction Information Modeling) that the Ministry of Land, Infrastructure and Transport was begun. At the CIM, it aims to use for each field of the investigation, the plan, the design, the estimate, the construction and the maintenance, crossing, but the procedures was just now begun and a related research is hardly done. It is expected that it leads to the improvement of the increase in efficiency and the quality such as mistake's reduction and the productivity improvement by using a 3D product model about the CIM, cooperating with the design, the estimate and the construction. In the this research, it reviewed the technique when utilizing the 3D product model of the CIM which was created with the detailed design for the substructure of the highway bridge for the estimate in the side of the employer and it reviewed what thing was necessary for a construction productivity to be improved by the CIM.
