In 2011, the UK Cabinet Office published the Government Construction Strategy. In
this report, the government stated its intention that, by 2016, it would require
“collaborative 3D BIM [building information modelling] (with all project and asset information, documentation and data being electronic) on all government projects”.
This statement was part of the government’s plans to modernise the construction industry, with the ultimate aim of achieving a 20% reduction in costs in the construction and operation of new buildings. Central to achieving this goal is the employment of building information modelling (BIM)to create a more efficient construction sector.
Information processing and collaboration, with data embedded within the model. Each discipline or organisation creates its own model, and these are subsequently amalgamated to provide a combined view of the entire project. Data is added directly to the model, dictating materials, functions, size and associated information. As documentation remains part of the information set, data can be linked to the elements of the model that it pertains to.
For many years, it seemed that every institution had its own definition of BIM. However, the UK BIM Task Group defines BIM as
“value-creating collaboration through the entire life-cycle of an asset, underpinned by the creation, collation and exchange of shared 3D models and intelligent, structured data attached to them”.
Essentially, BIM places information management and data exchange at the heart of the design process.
Previously, the design process in the construction industry relied on the systematic multi-stage issuing of drawings and specifications to contractors, from concept design to final construction and beyond. With BIM, it is about bringing together the data and different components to form a coherent set of information.
