BIM represents a new paradigm within AEC, one that encourages integration of the roles of all stakeholders on a project. BIM means not only using three-dimensional intelligent models but also making significant changes in the workflow and project delivery processes ( Hardin 2009).

It is important to note that BIM is not just software it is a process and software. As the model is being created, team members are constantly refining and adjusting their portions according to project specifications and design changes to ensure the model is as accurate as possible before the project physically breaks ground ( Carmona and Irwin 2007). 2006).īIM can be viewed as a virtual process that encompasses all aspects, disciplines, and systems of a facility within a single, virtual model, allowing all design team members (owners, architects, engineers, contractors, subcontractors, and suppliers) to collaborate more accurately and efficiently than using traditional processes. Construction documents such as drawings, procurement details, submittal processes, and other specifications can be easily interrelated ( Khemlani et al. Systems, assemblies, and sequences can be shown in a relative scale within the entire facility or group of facilities. Scopes of work can be easily isolated and defined. As a result, quantities and shared properties of materials can be readily extracted. The model can be used to demonstrate the entire building life cycle ( Bazjanac 2006). Different components of a building information model: MEP = mechanical, electrical, and plumbing (Courtesy of Holder Construction Company, Atlanta, GA).Ī building information model characterizes the geometry, spatial relationships, geographic information, quantities and properties of building elements, cost estimates, material inventories, and project schedule.

When completed, the building information model contains precise geometry and relevant data needed to support the design, procurement, fabrication, and construction activities required to realize the building ( Eastman et al. With BIM technology, an accurate virtual model of a building, known as a building information model, is digitally constructed. BIM simulates the construction project in a virtual environment. Building information modeling (BIM) offers the potential to achieve these objectives ( Azhar, Nadeem et al. The architecture, engineering, and construction (AEC) industry has long sought techniques to decrease project cost, increase productivity and quality, and reduce project delivery time. The findings of this study provide useful information for AEC industry practitioners considering implementing BIM technology in their projects. In this paper, current trends, benefits, possible risks, and future challenges of BIM for the AEC industry are discussed. It helps architects, engineers, and constructors visualize what is to be built in a simulated environment to identify any potential design, construction, or operational issues. This model, known as a building information model, can be used for planning, design, construction, and operation of the facility.
With BIM technology, an accurate virtual model of a building is digitally constructed. Building information modeling (BIM) is one of the most promising recent developments in the architecture, engineering, and construction (AEC) industry.
