Level of development (LOD) means a supposition with different definitions and executions. The level of development characterizes the content and reliability of BIM components at various phases or milestones. The “content” signifies geometric information, structured data and linked documentation.
The reliability signifies what has been utilized and to what extent the downstream users of the information can rely on the precision and quality of that content.
LOD is categorized as follow :-
LOD 100 – Concept Design
3D model of the building is formed to demonstrate the information on basic level. As a result only conceptual model can be produced in this phase. Several parameters ranging from area, height, volume, location and orientation are characterized.
LOD 200 – Schematic Design
General model where components are modeled with guess quantities, size, shape, location and orientation. Non-geometric information can also be added to the components of the model.
LOD 300 –…
