BIM Gets Specific about model elements

More acronyms are headed your way. LOD (Level Of Development), is a measure of the completeness of an element in a BIM. Not to be confused with "level of detail", level of development refers to more than just the geometric size of elements. Quite a few people in an industry working group called The BIM Forum, have developed the specification that defines what a measure of LOD means for building elements. They decided to organize the elements by CSI Uniformat, and then proceeded to describe five levels of development for each category (100, 200, 300, 350, and 400). 

This specification contains over a hundred pages of definitions. It should help to clarify the quality of BIM deliverables. However, standards only provide value if they are used. How this standard is adopted and applied through specifying, measuring, and managing elements, will be the true measure of it's success.

Tying LOD tightly into the BIM Execution Plan (BIMXP or BEP), has driven this effort to clarify the LOD definition. How far we can tip the balance away from the overhead of managing these elements and toward the value they provide, is the final and most important measure of effectiveness. Stay tuned.
