What is BIM 3D?

BIM 3D, or 3D Building Information Modeling, is a digital representation of physical and functional characteristics of a facility. BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its lifecycle; defined as existing from earliest conception to demolition. BIM 3D models can be used for visualization, clash detection, and coordination of various building systems before construction begins. This helps to reduce errors, improve efficiency, and lower costs. It is commonly used by architects, engineers, and construction professionals for design, documentation, fabrication, construction, logistics, and operation purposes.
