An Explanation of Building Information Modeling or BIM

BIM, or Building Information Modeling, is a digital planning, construction, and operation method that is more advanced than traditional 2D or 3D approaches. While 2D CAD is merely an electronic version of drawing on a board, and 3D models add volume and surfaces to plans, BIM allows for the use of individual building elements that are presented in 3D with accompanying information. Each object can be tagged with specific data such as its location, material specification, and cost. Plans, sections, and schedules can be produced directly from the model data, and changes in the view are immediately updated in all other representations. BIM models can also be analyzed and simulated for energy, light, and shadow studies. BIM eliminates the need for repetitive work and enables designers to focus on the more important decision-making tasks.
