Development of an Open BIM-based Legality System for Building Administration Permission Services

In Korea, the government has developed SEUMTER, an administration system for building-related public services, to facilitate and promote electronic submission and permission activities. SEUMTER is a progressive legality system based on 2D drawings for building administration permission services. However, there are a lot of problems related to the development of a legality system due to the complexity of Korean regulations, relationships and structures, the inefficiency of designing a legality system based on 2D drawings, the duplication examinations of documents (soliciting forms for civil affairs), and the drawings themselves. Therefore, the purpose of this study is to develop a legality system for building administration permission services based on open Building Information Modeling (BIM) in Korea. To achieve this purpose, the authors investigate the permission procedures and regulation structures used in current building administration permissions, then formulate an ideal permission procedure and regulation structure for the legality system in Korea. In addition, the authors investigate element technologies (for example, methods of structuring regulation, BIM model checker, BIM model viewer) for a legality system based on BIM and develop a prototypical legality checking software. Finally, the authors suggest strategies and future applications for a legality system based on BIM.
