New international standards on building information modelling (BIM)

BSI, the business standards company, has published two new international standards BS EN ISO 19650-1 & BS EN ISO 19650-2, which provide recommendations for the organization of information about construction works using Building Information Modelling (BIM). These two international standards, the first of the 19650 series, will supersede BS 1192 (principles) and PAS 1192-2 (capital/delivery phase).

Part 1, deals with the concepts and principles applicable to the whole life-cycle of a built asset from strategic planning and design, through maintenance and repair to end-of-life. The concepts and principles explained in this document should be adapted to the scale and complexity of the asset or project, to address the cost of implementing this standard.  This includes a National Foreword explaining terminology to assist the UK built environment sector.

Part 2, specifies requirements for information management, in the form of a management process, within the context of the delivery phase of the assets and the exchanges of information within it, when using BIM. The standard can be applied to all types of assets and by all types and sizes of organizations regardless of their chosen procurement strategy.  It contains a National Annex to align the ISO standard’s requirements with our national approach to BIM Level 2.

The audience for these standards covers those involved in the procurement, design, construction and/or commissioning of built assets; and those involved in delivering asset management activities, including operations and maintenance.

Ant Burd, Head of Built Environment at BSI, said: “The UK has led the way in developing information management process standards in support of Building Information Modelling (BIM) and these new international standards form part of our approach to share our experience and knowledge globally. 

“If we are to assist with the digital transformation of the global built environment sector then we need to develop internationally agreed best practice approaches. The BS EN ISO 19650 series is in effect the start of this journey and will assist the sector in improving its information management and collaboration on projects – both national and international – ultimately culminating in better quality assets that are delivered more cost effectively.”

Anne Kemp, Chair, UK BIM Alliance, Technical Director, ATKINS part of SNC Lavalin Group said: “It has been a major achievement to reach consensus in publishing the first two parts of ISO 19650, and I would like to thank all those involved who have made this possible. We have had to take into account thousands of comments (possibly unprecedented) over the past four years so it is a huge relief to have reached this milestone.  But this is only the start of the journey. Developing and publishing the standard would be a pretty pointless exercise if it wasn’t then adopted and implemented comprehensively across the industry. So in reality, this is where our work begins – and where the UK BIM Alliance comes in.  

“The Alliance has been set up to help the whole of the industry embrace BIM Level 2 as the first fundamental step on the journey to wider digital transformation. BSI, the UK BIM Alliance and CDBB are working together to develop a single guidance framework to assist the industry in doing this – ensuring common understanding and a clear way forward. The Alliance is open to all – if you would like to be involved, you will be welcomed with open arms.  And if you need help, just let us know.”

For organisations that have already implemented BS 1192 and PAS 1192-2, BSI has also published PD 19650-0: 2019 Transition Guidance to BS EN ISO 19650, which will help them understand any changes between the UK’s existing standards and the ISO standards replacing them. This will be available free with the purchase of either BS EN ISO 19650 part 1 and 2.

Two further standards in the BS EN ISO 19650 series are expected to publish in early 2020: Part 3 on managing the operational assess and Part 5 covering the security of BIM, digital built environments and smart asset management. These will replace PAS 1192-3 and PAS 1192-5 respectively.
