The Proposition of System for Total Design using 3D-CAD

Recently, Technical innovation utilizing ICT was realized in every field. Also in construction field, operational efficiency improvement was hoped between each process of life cycle of construction by managing ICT seamlessly. In this paper, focused on design process, informatization and quality enhancement of design phase were tried by using 3D data of construction information management in the life cycle of construction. The 3D-CAD was set on the base of design data, the whole of space of project area which contained designed objects, existed objects and the geography was considered totally from various aspects. Apply the method to a railway station vicinities improvement project and diversion aqueducts design, the proposed method was verified its effectiveness. Then the results of effectiveness and potentiality from case examples were considered.
