What is BIM?

The following Construction guidance note provides comprehensive and up to date legal information covering:

  • What is BIM?
  • Definition of BIM
  • How does BIM work?
  • Levels of BIM

Building Information Modelling, commonly known as BIM, is much talked about in the UK construction industry and is increasingly being used to improve efficiencies in the design and build process and increase collaboration amongst the project team. This Practice Note considers what BIM is and broadly how it works.

Definition of BIM

There is no universally accepted definition of BIM, however, one of the most commonly cited definitions is that of the Construction Project Information Committee, referred to in the BIM Overlay to the RIBA Outline Plan of Work, which defines it as 'a digital representation of physical and functional characteristics of a facility creating a shared knowledge resource for information about it forming a reliable basis for decisions during its life cycle, from earliest conception to demolition.'

As this definition describes, BIM is a way of working, it is not a mechanism, procedure or piece of software. It is essentially a method of project delivery which uses particular methods of information modelling and information management.
