6D BIM, an acronym for 6D Building Information Modeling and a term widely used in the Construction industry, refers to the intelligent linking of individual 3D CAD components or assemblies with all aspects of project life-cycle management information. The term is less commonly used in the UK and has been replaced with reference to the Asset Information Requirements (AIR) and an Asset Information Model (AIM) as specified in PAS1192-3:2014.
