Building Information Modeling (BIM) is a process by which a digital representation of the physical and functional characteristics of a facility are built, analyzed, documented and assessed virtually, then revised iteratively until the optimal model is documented. The virtual BIM model is not only graphical design but also a virtual database which includes the management data. So the construction manager (CM) can use BIM as a real simulation of the actual project. However, there is ambiguity about the compatibility of the traditional CM duties and responsibilities and BIM.This study looked into the construction management body of knowledge under twelve main subjects relative to the functions of BIM. It was determined that BIM is effective in the most critical phases of a project’s lifecycle. The duties and responsibilities of the CM must be updated to improve CMs’ efficiency in BIM-based projects.
