| BIM Level 0 | In its simplest form, level 0 effectively means no collaboration. 2D BIM drafting only is utilised, mainly for Production Information (RIBA Plan of Work 2013 stage 4). Output and distribution is via paper or electronic prints, or a mixture of both. The majority of the industry is already well ahead of this now (Source: https://www.thenbs.com/knowledge/bim-levels-explained) | Yes | ||
| BIM Level 1 | This is the level at which many organisations are currently operating. This typically comprises a mixture of 3D BIM for concept work, and 2D for drafting of statutory approval documentation and Production Information. BIM standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE), often managed by the contractor. Models are not shared between project team members. (Source: https://www.thenbs.com/knowledge/bim-levels-explained) | Yes | ||
| BIM Level 2 | This is distinguished by collaborative working – all parties use their own 3D BIM models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level. Design information is shared through a common file format, which enables any organisation to be able to combine that data with their own in order to make a federated BIM model, and to carry out interrogative checks on it. Hence any BIM software that each party used must be capable of exporting to one of the common file formats such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange). This is the method of working that has been set as a minimum target by the UK government for all work on public-sector work, by 2016.
