This guidance has been written to help individuals and organisations in the UK to understand the fundamental principles of building information modelling (BIM) according to BS EN ISO 19650 Parts 1 and 2. These are referred to in the rest of this guidance as the ISO 19650 series, ISO 19650 Part 1 or ISO 19650 Part 2. [1] Both parts were published in 2018. The ISO 19650 series has been written with the new user in mind, in other words someone who is not familiar with the 1192 standards.

This guidance is deliberately brief and high level – it describes some generic situations in implementing ISO 19650 but cannot give organisation-specific or project-specific details or application. The guidance is structured in a series of sections that start with broad, general topics and become progressively more specific. This is not the same as the ISO 19650-1 structure, but cross references to specific clauses in both ISO 19650-1 and ISO 19650-2 are given where relevant.

Detailed guidance is being prepared for the processes set out in ISO 19650-2 and this will contain more specific and practical examples. At the time of writing, this is expected to be published in its first edition in summer 2019. This two-pronged approach to publishing guidance was seen as the best solution for providing guidance quickly, whilst allowing time to consider those sections requiring more detail.

Together, these documents comprise the UK’s Guidance Framework to ISO 19650, and they are being jointly published by UK BIM Alliance, Centre for Digital Built Britain and BSI. They are intended to be read alongside ISO 19650 and must not be seen as a substitute for the standards themselves.

Readers should also be aware that a transitional guidance document for BS EN ISO 19650 was published by BSI in January 2019, aimed specifically at those who have previously been using BS 1192:2007+A2:2016 and PAS 1192-2:2013. The BSI document reference for this transitional guidance is PD 19650-0:2019. Refer to Transition guidance.

[1] BS EN ISO 19650-1 and BS EN ISO 19650-2 are the official designations of the standards published by BSI in the UK. Both contain national forewords and BS EN ISO 19650-2 contains a UK national annex. The shortened form of the designation is used in this guidance only to make the text more readable.
