Table 1
Definition of levels of development (LOD) in a building design process [12, 13].
Level
Brief description
Definition
LOD 100
Conceptual design
Vague information consisting of nongeometric data or line work, areas, volumes, zones, and so forth
LOD 200
Schematic design
Generic elements shown in three dimensions
LOD 300
Detailed design
Specific elements with object geometry (dimensions, capacities, and connections)
LOD 400
Construction
Shop drawing/fabrication
LOD 500
As-built (actual)
The project as it has been constructed. The model and associated data is suitable for maintenance and operations of the facility
