This paper proposes improved architectural drawing representations and drafting methods for efficiently deploying building information modeling (BIM) in practice. The first BIM-mandated public project in Korea was announced in 2009. Over the course of several projects, the architectural firms learned that traditional drawing representations and drafting methods were ineffective and time-consuming and that drawings could be represented more efficiently and clearly when BIM tools were used. However BIM-mandated public projects still require traditional drawing representations and file formats. This study analyzed the limitations of current drawing practices in Korea by comparing them with drawing representations and drafting methods used in the US and discussed how the drawing representations and drafting methods could be improved when BIM tools are used. It was found that the readability of drawings could be improved by eliminating redundant information between drawings, effectively using cross-referencing functions between drawing files, and actively deploying perspective views that could easily be achieved from BIM model.
