BIM & Standards
BIM Level of Detail (LOD 100 to LOD 500)
Standardized Definition
BIM Level of Detail (LOD) defines the progression of geometric richness and non-graphical asset information attached to elements within a 3D model. Ranging from LOD 100 (conceptual massing) through LOD 200 (generic geometry), LOD 300 (precise architectural/MEP sizing), LOD 350 (structural connections), up to LOD 500 (field-verified As-Built FM asset data).
Applicable Standards
- BIM Forum LOD Specification 2023
- ISO 19650
Industry Applications & Use Cases
- Specifying Exact Model Requirements for Scan-to-BIM Proposals
- Clash Resolution & Fabrication Detailing
- COBie Data Handover for Facility Management
