Building Information Modelling (BIM): A new paradigm for visual interactive modeling and simulation for construction project

The Architecture, Engineering and Construction (AEC) industries have long sought techniques to decrease project cost, increase productivity and quality, and reduce project delivery time. Building Information Modeling (BIM) offers the potential to achieve these objectives. 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 issues. BIM represents a new paradigm within AEC, one that encourages integration of the roles of all stakeholders on a project. It has the potential to bring about great efficiency as well as harmony among players who all too often in the past saw themselves as adversaries. In this paper, the benefits of Building Information Modeling (BIM) for the AEC industries are discussed with the help of two case studies. These case studies illustrate the various tangible and intangible benefits achieved by all stakeholders by implementing BIM in their projects. At the end, light is thrown on various BIM related risks and future challenges for the AEC industries.
