What is LOD? Define different LODs

Question

Accepted Answer

LOD stands for Level of Development. It defines the level of detail and reliability of BIM elements at different stages of a project.

LOD is a measure of the completeness and accuracy of BIM elements.
There are different LODs ranging from LOD 100 to LOD 500.
LOD 100 represents conceptual design with minimal detail, while LOD 500 represents as-built elements with precise geometry and information.
Each LOD has specific requirements and expectations for the level of detail and information.
LOD 200 is commonly used for early design stages, LOD 300 for detailed design, and LOD 400 for construction and fabrication.
LOD 350 is often used for coordination and clash detection, while LOD 500 is useful for facility management and maintenance.
