While Building Information Modeling (BIM) has become the industry standard, there are still challenges in management/communications about BIMs and this is impacting how teams rely on BIMs produced by others.

AIACC members have been integral in influencing the discussion and developing standards for Building Information Modeling. In early 2011, a working group was formed under the auspices of the BIMForum and began developing the Level of Detail (LOD) framework into a consensus-based standard that would be useful for defining, at the assembly and component level, the reliability of information contained in a BIM. This group divided the major building systems into four areas, and formed subgroups to address each area.

The intent of this effort is to help explain the LOD framework and standardize its use so that it becomes more useful as a communication tool. It does not prescribe what Levels of Development are to be reached at what point in a project but leaves the specification of the model development to the user of this document. To accomplish the document’s intent, its primary objectives are:

  • To help teams, including owners, specify BIM deliverables and to get a clear picture of what will be included in a BIM deliverable.
  • To help design managers explain to their teams the information and detail that needs to be provided at various points in the design process.
  • To provide a standard that can be referenced by contracts and BIM execution plans.

Between now and June 7, 2013
, the BIMForum LOD Working Group is seeking public comment on the first draft of the Specification. This can be downloaded at, where you will also find instructions for submitting comments.
