A Study on Automated Code Checking for Design Suitability of External Elements of Architectural Design Based on open BIM

Architectural design needs to go through design reviews such as laws and certifications, but errors and omissions can occur due to the large number of design books. As a solution to this, a BIM-based "design suitability automatic review study" is being conducted. In this process, the IFC object must be extracted independently, but unlike the internal elements of the building, the external elements of the building do not have individual IFC entities. In this study, we propose a method for distinguishing external elements of buildings for automatic review of design suitability based on BIM. External architectural elements that need to be reviewed were derived, and an object classification method was proposed using IFC Entity and a classification system. In addition, an automatic review flow chart was created to verify whether the object was classified. If the BIM-based architectural external elements proposed in this study are distinguished, it will be helpful for the development of design suitability research.
