In a BIM workflow, to support developing a conceptual electrical model, what is the mechanical design's minimum LOD that must show equipment size, shape, spacing, and location but not connections?

• A. 400 LOD
• B. 100 LOD
• C. 300 LOD
• D. 200 LOD

Answer: (C)

In BIM, you pick the level of development that gives you just enough detail to plan and coordinate without getting into fabrication specifics. For a conceptual electrical model, you need geometry that shows how big the equipment is, its shape, where it sits, and how far apart things are. This lets you plan routing, ensure there’s enough room for installation, and coordinate with other systems. At this stage, you don’t include how components connect to each other—that detail belongs to higher levels of development. So the minimum level you’d use is the one that provides accurate geometry and placement but stops short of showing connections.
