Abstract: “Using Building Information Modeling (BIM)-based design technology for various building design processes has been global and widely adopted in building construction projects. Many projects, however, are still conducted thru traditional 2D-based work methodologies, and there are some concerns when making submissions for building approvals derived from BIM-based design information. For example, when an applicant manually inputs information into a specific application form, subjectivity can become an issue. Human mistakes can be made during the input data process when there is some miscommunication between participants related a project. To address this problem, this paper proposed an improved BIM-based building approval system with a BIM-based information collection approach. To that end, we surveyed several countries where the building permit process use a web-based system. Then based on the information input method we classified the required information into two types: BIM-external and”
