ISO 19650 – new BIM standard

06 February 2019 #Construction

In January 2019, a new international standard for Building Information Modelling (BIM), BS EN ISO 19650 1&2:2018 “Organization of information about construction works – Information management using building information modelling”, was published.

This new international standard for BIM was developed on the basis of BS 1192:2007+A2:2016 and PAS 1192-2:2013, which it supersedes.  ISO 19650 defines the collaborative processes for effective management of information throughout the delivery and operation phases of built assets when using BIM.  Although it replaces the old standards, the processes it defines are practically identical.  There are however some “cosmetic” changes e.g. changes to terminology.

There is a UK National Annex to ISO 19650, which assists compliance with the new standard in the UK.  Paul Shillcock, one of the lead authors of ISO 19650, explains that “the idea is that ISO 19650-2 defines the requirements, and the National Annexes define the standards which must be used to meet the requirements in a particular region.”

For example, ISO 195650 at para 5.2.1 states that “The appointing party shall establish their exchange information requirement to be met by the prospective lead appointed party during the appointment.”  The UK National Annex clarifies that unless specified otherwise in the Project Information Standard, information models exchanged with the Appointing Party should include (a) geometrical information in proprietary formats or open data formats, (b) non-geometrical information in open data formats, structured in accordance with BS1192-4 (COBie) and contained within a single information container, and (c) documentation in open data formats.

The BSI also commissioned transitional guidance, including the mapping of terminology (which changed in ISO 19650 from the old UK BS 1192 and PAS 1192 standards to work in the international context) and key amendments, which is published as PD 19650-0.

Impact on ongoing projects

Any projects currently using BIM with reference to the old PAS and BS 1192 standards will continue to run with reference those standards.  However, if contracts contain a general clause warranting compliance with e.g. all applicable national and international legislation, regulation, and standards, then ISO 19650 may apply even though it is not specifically referred to.
