Building Information Models (BIM) and Virtual Design and Construction (VDC) have become standard tools in the project delivery process. The parties to a construction project create models for their internal use, but also increasingly rely on components provided by other project participants. Conversely, many practitioners are required to create BIM deliverables.

If we are not able to articulate requirements, plan execution, and measure and assess deliverables, we will over-produce or under-produce deliverables and create an inherently inefficient process. The concepts and standards around Level of Development (LOD) and Level of Information Needs (LOIN) are important for making the project delivery process effective and efficient and create positive outcomes for our projects.  


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.
