The application of 3D CAD has been gradually expanded in Japan. However, the use of 3D CAD is limited. There is no methodology which makes full use of Building Information Modeling (BIM) especially for the compliance of the Building Standard Law of Japan. This research aims to make clear the structure of the Building Standard Law of Japan, and to establish the methodology of compliance of the Law with BIM. First, this paper analyzes the provisions of the law with a questionnaire for architects and inspectors from the standpoint of the application of BIM. Secondly, this paper extracts the necessary items to check the compliance of the law. They are numeral 3D shape data, text data and object position data. Thirdly, this paper shows two kinds of methodologies for the compliance of the law with BIM, and examines the maximum height of building, the height of eaves and the fire-resistance as case studies. Finally, this paper points out the effectiveness and problems of methodologies for the compliance of the Building Standard Law of Japan with BIM.
