BIM | INTERNATIONAL STANDARDS GLOBAL REACH New BIM standards are being published, which are based on existing UK standards and documents. CIBSEs Carl Collins considers the key changes I n my article back in February last year, I spoke about the new international standards that were being developed for BIM, based on our existing standards and PAS documents under the 1192 series. The first of these standards has now been published and the corresponding 1192 ones withdrawn; what does this mean for construction professionals? This is the initial release of international standards that will be replacing our national ones over the next few years, and there are three documents you should be aware of. They are BS EN ISO 19650 Part 1, BS EN ISO 19650 Part 2 and PD 19650-0. The first two are the actual standards, complete with European and national forewords and annex; this is what makes them applicable to the UK market. However, it is the main body of the text that makes them widely applicable. The published document (PD) is guidance on the transition from our tried and trusted 1192 documents and the new 19650 standards. In short, there is actually not a huge amount of change, but some terminology has altered and it is worth talking a bit about that here. Also, the flow of the standards is different from that which we had before. The withdrawn BS 1192:2007 and PAS 1192-2 built on one another, while the ISO standards have a different delineation between them. The first part is about concepts and principles, while the second is about the actual delivery of BIM on projects. There will also be a more general guide to the 19650 series of BS 1192 BS EN ISO 19650-1 + National Foreword Probably the most noticeable change is that we no longer refer to BIM Level 2, but now BIM according to ISO 19650 standards produced by the British Standards Institution, which should be available in the next month or so. This will be an ongoing guide to the use of the standards, unlike PD 19650-0, which is purely about how you transition to the new standards. Some of the terms we have become accustomed to over the past few years have been changed to allow them to be translated into other languages more easily and accurately. It is worth looking at a few of them here. The changes PD 19650-0 Guide to BS EN ISO 19650 PAS 1192-2 BS EN ISO 19650-2 Changes to the flow of BIM standards: BS 1192 and PAS1192-2 have been superseded Probably the most noticeable change is that we no longer refer to BIM Level 2, but now BIM according to ISO 19650. This is a good change; we dropped the BIM Level 3 concept in favour of Digital Built Britain some time ago, so the Level 2 part was always a bit misleading. Another change is that from employers information requirements to exchange information requirements. The abbreviation EIR remains the same and the purpose also stays to specify what information an employer requires from a project team. The reason for the change is that the term employer does not retain the intended meaning when translated into some languages. As a result, the term employer has been removed from the rest of the standard and has been replaced 18 February 2019 www.cibsejournal.com CIBSE Feb19 pp18-19 BIM JR.indd 18 25/01/2019 18:23
