Building Information Modeling (BIM): Benefits, Risks and Challenges

Building Information Modeling (BIM) has recently attained widespread attention in the Architectural, Engineering and Construction (AEC) industry. BIM represents the development and use of computer-generated n-dimensional (n-D) models to simulate the planning, design, construction and operation of a facility. It helps architects, engineers and constructors to visualize what is to be built in simulated environment and to identify potential design, construction or operational problems. In this paper, the benefits and possible risks of BIM and future challenges for the construction industry are discussed. First presented is the main concept of BIM with its advantages and possible applications in construction. Then the role of BIM in the construction industry and academia is discussed based on the results of three recent questionnaire surveys. After that, a case study of Hilton Aquarium project in Atlanta is presented to quantitatively illustrate the cost and time savings realized by developing and using a building information model. It is followed by data from 10 construction projects to determine the net BIM savings and BIM return on investment. At the end, BIM risks and future challenges for the construction industry are discussed.
