2013 CIB Tokyo IDDS&BIM Oneday Seminar (11/1) Study on application BIM technologies for building certification on technical standards conformity -Introduction of research of the BIM technology in the Building Research Institute Masaki MUTO, Dr. Eng. Senior Research Engineer Dept. of Production Engineering, BRI 1 Summary • To introduce electronic submission for building certificate procedure including BIM technology are expected for streamlining on confirmation of building technical standards. And some countries already started electronic submission with BIM technology now, e.g. Singapore. • Building Research Institute executes the R&D project which is aimed to clarify bottlenecks in conventional building certificate procedure, subjects of introduction electronic submission and application possibilities of BIM on the procedure from FY2012 to FY2014. This topic gives a progress report of our R&D. 2 BRI ‘s R&D Activities The Building Research Institute (BRI) has been conducting various research and development from the fair and neutral perspective of a public-sector research institute. 4 Targets of R&D shown by the MLIT Realization of Sustainable Housing, 1) Buildings and Urban Communities by Green Innovations Realization of Secure and Safe 2) Housing, Buildings and Urban Communities Maintenance and Revitalization of Existing Housing, Buildings and Urban 3) Communities Coping with the Declining and Aging Population International Contributions by Building 4) and City Planning Technology and Response to Informatization 3 Typical Procedure of building certification Applicant Confirmation Application drawings and its contents body 配置図 高さ、道路幅員・・・ 各階平面図 各室の用途、床面積・・・ CAD 断面図 居室の天井高さ・・・ 仕上表 Architect 令129条規定部分・・・ ○○××㊞ (Substitution) Architect’s seal is needed.

Since the application is made on the basis of paper medium, confirmation body is regarding as problems the preservation place and its cost, or documents lost. Since CAD is generally used, is submitting digitized application documents and confirming possible? 5 Backgrounds 2/2 After the incident which camouflaged earthquake resistance (called “Aneha” incident), the procedure of the building confirmation tightened and change of the contents in the procedure became difficult. Therefore, the preliminary consultation before a “formal reception” is prolonging the confirmation period so that there may be no inconsistency in the contents of application documents. Is the BIM technology which can unify building properties inapplicable? 6 The aim of this research To develop the technology of the electronic application of the building confirmation for achieving the following aims; (1) Digitize the document for application preserved by the confirmation body. (2) Improve the compatibility of the descriptive content of documents for mitigating a labor required for confirming work. 7 Perspective of development Confirmation Applicant Application documents and its contents C body 配置図 高さ、道路幅員・・・ on v e 各階平面図 各室の用途、床面積・・・ n t i o 断面図 居室の天井高さ・・・ n a l 仕上表 令129条規定部分・・・ confirmation by paper based CAD ○○××㊞ documents S PDF t CAD e d p Photo scanned image o confirmation by 1 c method of compatibility reservation u Scanned image m e PDF n DXF etc XML etc. t f St o e electronic r p e-documents contents data m 2 signature a confirmation by t 3D Building model replaced s e-documents w/ / contents data with sealing w S BIM o Viewer t e r k p fl 3 o w BIM model data definition of Property (unified) IFC XML etc. confirmation by 8 sets and model view BIM model data Perspective of development Confirmation Applicant Application documents and its contents C body 配置図 高さ、道路幅員・・・ on v e Development of the data str各u階ctu平r面e 図of a b各u室ilのdi用n途g 、床面積・D・e・ velopment of the information usne t i o design 断面図 居室の天井高さ・・・ process in building confirmation n a l Product Model = IFC, IFD Process Model = IDM, MVD 仕上表 令129条規定部分・・・ confirmation by paper based CAD ○○××㊞ documents S PDF t CAD e d p Photo Scanned image o confirmation by 1 c method of compatibility reservation u Scanned image m e PDF n DXF etc XML etc. t f St o e electronic r p e-documents contents data m 2 signature a confirmation by t 3D Building model replaced s e-documents w/ / contents data with sealing w S BIM o Viewer t e r k p fl 3 o w BIM model data definition of Property (unified) IFC XML etc. confirmation by 9 sets and model view BIM model data Detail of development steps contribution to problem solving (2) S (1) Target of Improve the t Digitize the development Core technology needed compatibility e document step of the p for descriptive application content of documents confirmation by •electronic signature (= long term signature and multiple Scanned image signature) corresponding to image file format 1 Good n/a •workflow diagrams or document formats corresponding to electronic submission confirmation by (Add to Step 1.) e-documents w/ •electronic signature (= long term signature and multiple 2 contents data signature) corresponding to data file format Excellent Good •method of compatibility reservation between e- document and contents data confirmation by (Add to Step 1.)
