CIC BIM Protocol

The Construction Industry Council (CIC) Building Information Modelling Protocol: Standard protocol for use in projects using Building Information Models (the CIC BIM Protocol) was first published in February 2013. It was commissioned by CIC as part of its response to the UK Government Construction Strategy which stated that '...Government will require fully collaborative 3D BIM (with all project and asset information, documentation and data being electronic) as a minimum by 2016'.

This represents a requirement for Level 2 BIM on centrally-procured public projects. Level 2 is a managed 3D environment with data attached, but created in separate discipline models.

The CIC BIM Protocol claims to be suitable for use on all Level 2 BIM projects. It can be downloaded from the website of the BIM Task Group, along with two appendices, guidance notes and model contract amendments. It is a 7 page supplementary legal agreement that can be incorporated into professional services appointments, construction contracts, sub contracts and novation agreements by addition of a model enabling amendment. It establishes specific obligations, liabilities and limitations on the use of building information models and can be used by clients to mandate particular working practices.

It is one of a number of standards, protocols and tools available to support the adoption of level 2 BIM in the construction industry:

The protocol is a contractual document that takes precedence over existing agreements. Clause 2.1 states '…In the event of a conflict or inconsistency between the terms of this Protocol and any other documents contained in and/or forming part of the Agreement, except where the Protocol states otherwise, the terms of this Protocol shall prevail.' Parties to the protocol may wish to consult their insurers to seek confirmation that they are not accepting un-insured contractual duties by adopting the protocol.

It is important therefore that the protocol and its appendices are made available pre-appointment and that changes to it or its appendices are treated as variations to the contract, following suitable change control procedures.

The protocol provides the definition of responsibilities, liabilities and limitations for project team members and defines deliverables to a specific level of detail (LOD) for 'data drops' at key stages during the development of the project. This is set out on a project-specific basis in a Model Production and Delivery Table (MPDT) in Appendix 1 to the protocol. Appendix 2 sets out the information management standards that will be adopted.

The protocol requires that the client appoints an information manager. This appointment may change through the course of the project (for example the lead designer or lead consultant may be the information manager during the early stages but then the contractor during construction). The information manager is not a BIM co-ordinator and has no responsibility for clash detection or model coordination. They are essentially a procedural gate-keeper, policing the model to ensure it follows the protocol and that the data is secure.

As with copyright on conventionally designed buildings, the protocol grants a licence to the client to use the information contained in the model(s) produced for the 'permitted purpose' (ie for the purpose for which that level of detail of information was intended). A sub-license from the client enables project team members to use models prepared by other project team members, but if the client wishes third parties to use the model, a new license may be required.

The protocol guidance advocates the use of collaborative practices and the adoption of PAS 1192-2 (Publicly Available Specification for information management for the capital/delivery phase of construction projects using building information modelling), but there are no references to such practices or specifications in the protocol itself.

The CIC's warns that any future move to Level 3 BIM (the creation of a single, online project model with construction sequencing, cost and lifecycle management information) may raise very different issues of responsibility, copyright and liability that will require the development of new protocols.
