Abstract
This research focuses on documenting modern architectural heritage with the aim of enhancing the efficiency of this process using Building Information Modeling (BIM) in construction. The study involves an examination of the concepts and workflows of Modern architectural BIM and Documented BIM, highlighting their differences. Through a case study of Choheungsanghoe in Incheon, this research identifies the types of information and information input features required in the Documented BIM process. In conclusion, the Documented BIM for modern architectural heritage can significantly improve efficiency by refining workflows and enhancing data granularity. For modern architectural heritage like Choheungsanghoe in Incheon, which lacks mandatory regulations and official support, the aging process can easily lead to damage, alteration, or loss. However, Documented BIM, as a preservation record, serves as an effective tool to address these challenges and needs.
