Study on BIM Utilization for Design Improvement of Infrastructure Project

Virtual construction could be done by using Building Information Modelling technology. But, to do that, information and knowledge on construction phase or fabrication phase should be available in design stage. In Japan, MLIT had been taking the leadership in the CALS/EC project which was just partially successful. We have to learn from “the experiences of CALS/EC” to get the fruit from BIM introduction to infrastructure projects. In the case of design-bid-build contract, since data sharing should be restricted based on the contract, consultants or engineers for designing are to become more capable of utilizing information relevant to construction of fabrication. The mobility of personnel is to be promoted in construction industry. In the case of design-bid-build contract, since data sharing should be restricted based on the contract, public sectors have to be more positive overcome contract related issues with their own leadership. If public sectors in Japan would not notice the similarity of issues of CALS/EC and BIM, Japanese construction industry may experience the same kind of frustration as one they had while executing CALS/EC projects.
