How to better define information requirements for our clients and projects? In the digital construction community the concept of “LOD (Level of Definition/Detail/Development etc)” has been created and used. However to allow more automation, more granular requirements are needed. In this session you will learn more on the history of this topic and how it evolved to the new concept of “Level of Information Need” included in the latest series of international standards related to Building Information Modelling (BIM): the ISO 19650 series. You will have the opportunity to meet the lead author of the standard EN 17412-1 on Level of Information Need and discover how this can be linked to LOD.
