A Level of Development Specification for BIM ProcessesAECbytes Archived Article (May 16, 2013)

In 2008, Jim Bedrick published an article in AECbytes entitled “Organizing the Development of a Building Information Model” in which he introduced the concept of LOD. At that time, the acronym stood for “Level of Detail.” Since then, a lot of work has gone into the LOD framework by organizations including the the AIA California Council IPD committee, the AIA Contract Documents Committee, and the AGC’s BIMForum. The concept has evolved into “Level of Development” and it is discussed in depth by Jim Bedrick in this follow-up article.
