LOD 100-500
About this calculator
Level of Development (LOD) is a scale defining the accuracy and information quantity in BIM models, ranging from LOD 100 (basic concept) to LOD 500 (executable with construction-ready data). Each level corresponds to a project phase: LOD 100 for concept, LOD 200 for planning, LOD 300 for design, LOD 400 for execution, and LOD 500 for final as-built. Choosing the right LOD affects costs, time, and project clarity.
This tool maps the required LOD for each construction lifecycle stage. For example, LOD 300 suffices for budgeting, while LOD 500 is critical for on-site coordination. Users should consider the project phase and stakeholder requirements before defining LOD. Excessively high levels may add unnecessary complexity, while low levels can hinder critical decisions.
Use LOD to align expectations among architects, engineers, and contractors. Document elements requiring higher precision in early stages to prevent rework, and ensure specifications match on-site reality in advanced phases.
Frequently asked questions
What is the difference between LOD 300 and 400?
LOD 300 defines geometry and attributes for budgeting, while LOD 400 includes technical details for on-site execution, such as component exact placement.
How to choose the right LOD for a project?
Assess the project phase and stakeholder requirements. LOD 100 is for concept, LOD 500 for finalization.
Can different LOD levels be mixed in a model?
Yes, but clear documentation is essential to avoid confusion between elements with varying detail levels.
Does LOD affect project costs?
Yes. Higher levels require more time and resources but ensure accuracy. Avoid exceeding necessary levels.
