Building Information Modeling (BIM) is an intelligent, model-based process that starts in the early stages of planning and design. It is used through construction, and can also be used throughout the operational management stages. BIM projects can display the proper graphics at different scales, represent accurate geometry, and can be rich with manufacturer product data.
