BIM is not actually a new term, but it is a term which not all planners are familiar with, so it is worth covering as part of this series, especially as next we will look at the related term Digital Twin.
BIM stands for Building Information Modelling. It is an information system to support the design, construction and operation of a building project (the ‘B’ stands for building as a verb not building as a noun, so it can be used for any construction project). All the information about the project sits in a structured way so that experts can access, use and add to this data as the project is developed from a design concept to an operating asset.
BIM sometimes refers to the digital 3D model which sits within the information and from which architectural drawings can be generated, however BIM is really the whole process of a building project. With BIM in place, other modern technologies can support the development of the building and increase efficiencies. For example, project managers can now don VR headsets and virtually explore the modelled building.
Governments in the UK, the US and Scandinavia have made BIM compulsory on publicly funded projects due to the benefits of BIM across the lifecycle of a building. NZ government policy requires BIM on larger government projects, and encourages it for most other publicly funded projects except those simple projects under $1million.
