Recently, as there has been high interests in Building Information Modeling (BIM), there are studies and movements to adapt this new paradigm in both academic field and industrial field. While, Reinforced concrete structure is a mainly used structural system in Korea. However, it is limited the development of reinforced concrete system in BIM comparing to that of steel structures. The primary reason is that it is not interoperable the information on reinforcement in RC structures and the progress of modeling reinforcement has a low productivity for a reinforcement object being created manually by user in the BIM platform. For the requirements, ARPM(Automatic Reinforcement Placing Module) has been developed to connect structural analysis and design database to BIM platform, to perform the design of reinforcement placing and to draw reinforcement in BIM platform, in this study. By developing the ARPM, it is expected to raise the productivity of the construction for RC structures and increase the effectiveness in the current modeling process in BIM platform.
