Building Information Modeling (BIM) is a digital representation of a physical and functional form of a facility underpinned by the creation, collation and exchange of shared 3D models, structured data and asset attached to them. In May 2011 the Cabinet Office published the Government Construction Strategy, announcing its requirements for level 2 collaborative 3D BIM on its projects by 2016. To successfully implement BIM for Key Output 2 (KO2) of the Thameslink Programme it was important that a common set of processes and procedures were used.
The processes which were adopted outlined the co-ordination of the project model files (2D and 3D) and the production of 2D drawings from 2D and 3D models (these processes are outlined in Thameslink Programme’s Processes and Procedures). Throughout all Thameslink Programme procedures for Utilities, Survey and CAD there is consistent requirement for level of detail to meet the Government-set BIM requirements.
