BIM Level 2 has been the aim for RVW and many of our peers since 2011.

For a project to be classified as BIM Level 2 it has to be fully compliant with PAS 1192-2:2013, there is no halfway house.

In the first instance you would have the (EIR) which is produced by or on behalf of the employer and forms part of the appointment and tender documents on a BIM Project. The EIR define the information that needs to be produced at each project stage – together with the required level of detail and definition.

A BIM Execution Plan (BEP) will then need to be created by the project team to address the issues raised in the EIR and to explain the supplier’s methodology for delivering the project using BIM. The BEP is document that is fed into by all design team members informing how the project will be managed (including by whom), how it will be authored to ensure compatibility, how it will be managed in terms of what standards are used and how information will be shared / approved then ultimately how the information will be handed over at the end of the design and construction phase.

All parties produce and share their own 3D models in a common file format that is combined into a federated model. This federated model is then interference checked (clash detection) for compliance and potential risk items.

All drawings and documents are produced and managed to BS1192:2007

A Common Data Environment (CDE) is set up (often by the contractor) to share information which has a built in approval system and document containers that comply with PAS 1192-2:2013

COBie (Construction Operations Building Information Exchange) data is embedded into the model that is capable of being exported to compatible Facilities Management software and .ifc format.

What can you get out of 3D models and the BIM process?

As well as the collaboration and co-ordination advantages of designing and detailing in 3D there is so much more you can get out of the BIM process..........
