Explaining LOD Simply and Graphically

How do you easily explain LOD in a way that will stick with the PM’s in your firm?  I have struggled with this question for some time.  The “Level of Development Specification” is a great reference but I think it’s missing the Architectural LOD Graphical representation.

So after trying several ways to explain the differences in Level of Development and that Level of Detail is different I had an idea.  I came up with a set of plans that would show a building at different levels – simply.  I took definitions out of the BIMForun document that coincide with AIA Document E202-2008.

I only modeled to LOD 300, which is our Construction Document Deliverable.

100: Overall building massing indicative of area, height, volume, location, and orientation may be modeled in three dimensions or represented by other data.

200: Model elements are modeled as generalized systems or assemblies with approximate quantities, size, shape, location, and orientation.

300: Model elements are modeled as specific assemblies accurate in terms of quantity, size, shape, location, and orientation.

400: Model elements are modeled as specific assemblies that are accurate in terms of size, shape, location, quantity and orientation with complete fabrication, assembly, and detailing information.

500: Model elements are modeled as constructed assemblies actual and accurate in terms of size, shape, location, quantity, and orientation.
