When drafting a contract or building execution plan, specifying the required Level of Development (LOD) is crucial.
The LOD Scale Explained
- LOD 100 - Conceptual Design
- Elements are represented as basic symbols or conceptual volume outlines.
- LOD 200 - Schematic Design
- Elements are modeled with general quantities, shapes, and location paths.
- LOD 300 - Detailed Design
- Elements are represented as specific systems with precise dimensions and geometries.
- LOD 350 - Spatial Coordination
- Includes specific connections, brackets, anchors, and interfaces.
- LOD 400 - Fabrication Ready
- Detailed models featuring weld specifications and joint splits ready for offsite fabrication.
- LOD 500 - As-Built Record
- Field-verified models matching exact built locations with maintenance manuals.
