The Alliance is producing new guidance for the UK National Annex to the ISO 19650 series – the international standards that specify how practitioners manage, organise and digitise information about buildings and civil engineering works

The UK BIM Alliance is asking for landscape practitioners in the UK to contribute to the latest revision of the UK BIM Framework.

The BIM Framework is how built environment industries in the UK implement information management according to the ISO 19650 series, Information management using building information modelling (BIM). The National Annex to BS EN ISO 19650-2 is part of this Framework, and contains the UK-specific recommendations for information management on projects.

N.B. A National Annex (NA) provides guidance on the application and applicability of a European or international standard. It is usually published within the UK implementation of the standard.

This National Annex was initially prepared at the time ISO 19650-2 was being published in late 2018. Now, the National Annex has been revised based on feedback that it did not perform as efficiently as expected. Published in February 2021, the new update is officially titled BS EN ISO 19650-2:2018 & Revised NA.

In line with the revision to the National Annex, the UK BIM Alliance – which the Landscape Institute recently joined – is developing new and revised National Annex Guidance. The next release will explain how all project parties, including landscape architects, can apply the 2021 National Annex throughout the delivery phase.

Several members of the the LI’s Digital Practice Group have made useful contributions into both the Annex and the guidance documents. Martyn Horne, contributing author to the guidance, is asking LI members to get involved:

We’d like to invite members to propose situations or scenarios that you would like us to address in the next edition. You can send these to or alternatively, directly to me at
