Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.
