Have you ever wondered what people mean when they say “LOD 300” or “LOD 500” in BIM projects?

LOD (Level of Detail / Development) defines how much information and accuracy a model element holds.

Here’s a quick breakdown 👇

🔹 LOD 100: Conceptual — massing, shape, and overall volume.
🔹 LOD 200: Approximate geometry — basic model with estimated locations.
🔹 LOD 300: Accurate geometry — ready for coordination and documentation.
🔹 LOD 400: Fabrication level — includes manufacturing details.
🔹 LOD 500: As-built — the final, field-verified model.

Each stage of LOD ensures better collaboration, cost estimation, and construction planning.

What I love most is how LOD helps align the entire project team — from architects and engineers to contractors — ensuring everyone is working on the same level of precision.

BIM isn’t just modeling; it’s building smarter with data.
