A large percentage of the AEC industry use the phrase BIM Model, I myself have used it causing me to blush when it comes out of my mouth. It’s time to listen to James Vandezande and save a Fluffy Kitten!
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.
