BIM is an acronym for Building Information Management. It describes the means by which everyone can understand a building through the use of a digital model.
It brings together all of the information about every component of a building, in one place. It makes it possible for anyone to access that information for any purpose, e.g. to integrate different aspects of the design more effectively. In this way, the risk of mistakes or discrepancies is reduced and abortive costs minimised.
Modelling an asset in digital form enables those who interact with the building to optimise their actions, resulting in a greater whole-life value for the asset.
BIM is a way of working; it is information modelling and information management in a team environment.
All team members should be working to the same standards as one another. BIM creates value from the combined efforts of people, process and technology.
BIM data can be used to illustrate the entire building life-cycle, from inception and architectural design to demolition and materials reuse.
Spaces, systems, products and sequences can be shown in relative scale to each other and, in turn, relative to the entire project.
