open BIM is a format that allows each and every project member to access the information model. It is a universal approach to collaborate with design, realise, and operate buildings based on open standards like IFC, BCF, and others.
BIM is often referred to as software or technology. It is much more than that. It is actually a sequence of processes or workflows used throughout the design, construction, and use of a building. BIM defines who does what, how and when.
