Information Delivery Manual (IDM)

The built asset industry is characterized by bringing many different stakeholders together in a project-specific organization. In order to work efficiently, it is necessary for all participants to know which and when different kinds of information have to be communicated. The ISO 29481-1:2010 “Building Information Modelling - Information Delivery Manual - Part 1: Methodology and Format” standard has been developed by buildingSMART in order to have a methodology to capture and specify processes and information flow during the lifecycle of a facility.  More information is found here.

"Experienced practitioners who have since introduced BIM in their daily practice are aware of the importance of a coordinated understanding of the BIM objectives and BIM use cases in their projects. This results in process-oriented information exchange requirements, which then have to be transported in the form of data for a specific purpose. The IDM standard (Information Delivery Manual) helps to document these necessities with a uniform method, so that a common understanding is created and the information need can be coordinated purposefully."
