AEC (UK) Layer Protocols v4 underway

28 March 2013

Following hot on the heels of the publication of the AEC (UK) BIM Protocol For GRAPHISOFT ArchiCAD v1.0, the AEC (UK) committee is now beginning work on an update to the Layer Standards. Now known as the AEC (UK) Layer Protocols, it brings the classifications up-to-date for the recently released Uniclass v2.


AEC (UK) BIM Protocols for GRAPHISOFT ArchiCAD published

28 March 2013

Today sees the release of version 1 of the AEC (UK) BIM Protocols for GRAPHISOFT ArchiCAD. The document and its supplementary checklists can be downloaded free of charge from

AEC (UK) chair, Nigel Davies, commented, “The ArchiCAD committee has done a great job with this first release, and we thank Rob Jackson and the rest of the team for their hard work compiling the protocols. It’s an important step in the profile of the AEC (UK) work, demonstrating that BIM is not based on one piece of software alone; it’s important people are able to choose the right tool for the right job, yet be assured that there is a consistent approach to sharing models and data between the tools of their trade. The AEC (UK) Protocols go a long way to providing that consistent, best practice working.”




AEC (UK) BIM Protocols v2.0 now available

7 September 2012

The latest version of the AEC (UK) BIM Protocols is now available for download from the Documents page.

Version 2.0 of the AEC (UK) BIM Protocol is a unification of the guidance provided by the previous documents, bringing workflows together in a single generic document which can be applied to any BIM-enabled project. The set of documents builds on the guidelines and frameworks defined by the UK standards documents, including BS1192:2007 and the forthcoming PAS1192-2:2012 alongside proven best practice procedures, providing a clear, concise path to implementation for BIM authoring software, such as Autodesk Revit and Bentley’s AECOsim Building Designer.

The AEC (UK) BIM Protocol v2.0 forms the “hub” of a complete software-based solution. Supplementary documents provide additional detail and enhancements required to implement these protocols using specific BIM authoring software:

Nigel Davies, chair of the AEC (UK) initiative, comments, “The UK construction industry is moving through an exciting period of rapid change. The Government’s BIM strategy is affecting all of us, the private sector as well as public. We see this release of the AEC (UK) BIM Protocol as critical in helping cut through the often very technical wording of the Government’s BIM Task Group documents and British Standard procedures, allowing companies of any size to work in a coordinated and consistent manner with BIM.”


19 June 2012

Work is now under way on version 2.0 of the AEC (UK) BIM Protocols. An exact timeline will be published soon, but the committee is now reviewing change requests we have received. As an insight, the new version will:

  • Amalgamate and rationalise the protocols from the Revit and Bentley Building versions
  • Redevelop the generic document to apply to all BIM authoring tools
  • Provide product-specific appendices to implement the protocols for specific software
  • Include closer alignment with BS1192:2007 and other British Standards (BS8541-1 and PAS1192-2)
  • Integrate the protocols with the project process through a Project Execution Plan

Please let us have any comments or questions you may have by posting a response to this post. We may not publish all of them, but we will read, and take on board, all comments you send.


30 September 2011

Today sees the launch of the latest document in the AEC (UK) portfolio: the AEC (UK) BIM Standard for Bentley Building products. The standard is released to compliment the previous Autodesk Revit document, ensuring that consistent methods and approaches are available for the most common BIM authoring platforms. This Standard focuses primarily on adaptation of those standards for practical and efficient application of Bentley Architecture, Bentley Structural Modeller and Bentley Electrical and Mechanical Systems, drawing on best practice and proven workflows.

The AEC (UK) BIM Standards draw on guidelines from BS1192:2007 and other world-wide sources of BIM production methods. They do not replace, but instead to provide a practical implementation to any company seeking to adopt a working solution. Nigel Davies, chair of the AEC (UK) committee explains, “The importance of these standards cannot be underestimated. In the bigger picture of BIM development and standardisation in the UK, the AEC documents provide a working implementation of those codes. Our aim is to provide continual updates to align with the major initiatives taking place. Where guidance doesn’t yet exist, we help to bridge the gap between non-standardisation and a unified framework.”

Of particular note in this release:

  • Definition of BIM modelling workflows and co-ordination of collaborative working
  • Advice on separation of modelling data, reference use and procedures
  • Workspace organisation
  • Object naming recommendations

If your company uses, or is considering the adoption of Bentley’s BIM authoring tools, this document will assist you in their configuration, installation and use.
