BIM technically is based on the object-oriented computer aided design (CAD) tools, which mean BIM objects can represent building elements, embed key information of those building elements into it (Ibrahim and Krawczik, 2003; Lee et al. 2006; Eastman et al. 2003, 2004). BIM has been applied throughout the project life cycle such as design collaboration, IPD, facilities management. There are a number of papers investigating BIM and its effect on project risks, costs, performance.
