The proposed definition of the National BIM Standards Committee (NBIMS) defines Building Information Modeling as “a complete digital representation of physical and functional characteristics of an infrastructure. A BIM model is a source of information for a building – infrastructure, thus creating a reliable basis for decision making throughout the building life cycle, which is available from the early design stages up to the demolition”.
However, the BIM methodology is not limited to the design and / or study. Its use and its benefits extend to all phases of the project life cycle, supporting services such as cost and project management, constructability and operations management. The end product of such an all-inclusive process is not just a better building or a simple 3D model on the computer. It is a multitude of information in harmony with the – virtual and physical – result which can be used for any future use (e.g. maintenance).
