Building Information Modeling (BIM) and the Construction Management Body of Knowledge
IFIP Advances in Information and Communication Technology
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
... t 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. processes more effectively. Developments in IT have affected the CM's duties and responsibilities and therefore, are expected to change the practice of construction management too. IT systems used today in construction encompass all disciplines and are used to describe and document the contributions of each member of a project team  . The most current IT product is Building Information Modeling (BIM) which 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  . BIM is not only a 3D virtual representation of building, but also a giant database which includes significant information packages for the basic construction management practices such as estimating, scheduling, change orders, etc. So, the designer can use BIM as a real simulation of the actual project before real construction starts. However, there is ambiguity about the compatibility of the construction management body of knowledge and BIM. Computerization has improved speed and accuracy in most construction management services. Web-based systems have improved access to information, communication between parties and overall efficiency. The basic practices of construction management involve the use of sophisticated computer tools. Budget, schedule, risks, constructability, etc. are modeled and analyzed before the execution of the actual project and tracked during the construction process on the computer screen. These computer tools allow CMs to perform their duties with great speed and accuracy. Most CMs are familiar with traditional practices that involve basic computer tools, but should they also need to get acquainted with BIM and should they explore ways to integrate BIM applications into their duties? The objective of this study is to investigate whether there is a need for updating the current construction management body of knowledge with respect to the emerging BIM technology, hence updating the CM's duties and responsibilities in response to developments in BIM. Methodology This study investigates whether the construction management body of knowledge is up to date relative to developments in BIM. The twelve subjects in the body of knowledge were extracted from the Construction Extension to A Guide to the Project Management Body of Knowledge  . A comprehensive literature review was performed to understand how BIM affects the basic functions of construction management.
