LOD

Level of Development (LOD) specifies the degree of detail and reliability of BIM model elements at different stages of a project. It defines both the geometric detail and the information richness of model components, ensuring clarity about what can be expected from a model at each project phase.

• Defines degree of detail and reliability at different project stages

• Specifies both geometric detail and information richness

• Ensures clarity about model expectations at each phase

• Maps to specific project phases from concept to operations
