AGC BIMForum Level of Development Specification that has been released for review and comment

Level of Development or Lots of Lines (Alix and Cindy, feel free to use that "line").
Maybe, BIM Level of Difficulty?

Ladies and gentlemen, this is one of the most important and "this will kick you in the ass if you don't pay attention" aspects of BIM. Even if you don't fill out the survey, you'd better study this, especially if you're a subcontractor.  


AGC BIMForum Level of Development Specification that has been released for review and comment

The AGC is looking for input on the draft version of the AGC BIMForum Level of Development Specification that has been released for review and comment on April 24th, 2013.
This is to be a supplement to help with use of the AIA E-202 contract document.
The AGC is looking for comment and criticism of the document before June 7th 2013.

The Level of Development (LOD) Specification is a reference that enables practitioners in the AEC Industry to specify and articulate with a high level of clarity the content and reliability of Building Information Models (BIMs) at various stages in the design and construction process. The LOD Specification utilizes the basic LOD definitions developed by the AIA for the AIA G202-2013 Building Information Modeling Protocol Form and is organized by CSI Uniformat 2010.  It defines and illustrates characteristics of model elements of different building systems at different Levels of Development. This clear articulation allows model authors to define what their models can be relied on for, and allows downstream users to clearly understand the usability and the limitations of models they are receiving.

The intent of the Specification 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 progression to the user of this document. To accomplish the document’s intent, its primary objectives are:

·         To help teams, including owners, to 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.
