LOD 100 - Concept Design 

The building 3D model is developed to represent the information on a basic level. Only conceptual model creation is possible at this stage. Parameters like area, height, volume, location, and orientation are defined.

LOD 200 - Schematic Design 

This is a general model where elements are modeled with approximate quantities, size, shape, location, and orientation. Non-geometric information can also be attached to the model elements.

LOD 300 - Detailed Design 

The model element is graphically represented within the model as a specific system, object, or assembly in terms of quantity, size, shape, location, and orientation. Non-graphic information may also be attached to the model element.

LOD 350 - Construction Documentation 

This includes model detail and elements that represent how building elements interface with various systems and other building elements with graphics and written definitions.

LOD 400 - Fabrication & Assembly

Model elements are modeled as specific assemblies, with complete fabrication, assembly, and detailing information in addition to precise quantity, size, shape, location, and orientation. Non-geometric information can also be attached to the model elements.

LOD 500 - As-Built

Elements are modeled as constructed assemblies for maintenance and operations. In addition to actual and accurate size, shape, location, quantity, and orientation, non-geometric information is attached to modeled elements.
