LOD (Level of Development) helps parties discuss the development and usability of model elements. It should be agreed in the BIM execution plan, alongside information requirements and each party's responsibilities.
Choose for the intended use
Mishima's service brochure outlines LOD 100–200 for concept and basic design, LOD 300–350 for technical coordination and clash checks, LOD 400 for fabrication and shop drawings, and LOD 500 for field-verified models supporting as-built records and operation.
These are service-scope guidelines. Specific requirements must be set for each element, discipline and purpose; a single LOD value should not be assumed to describe an entire building in full.
Questions to clarify
- Will the model support design review, construction coordination or operation?
- Which elements need detailed information, and which only need indicative geometry?
- Who is responsible for updating, checking and validating the data?
- What are the acceptance criteria for the model and handover documents?
Avoid detail that adds no value
Adding detail before it is needed can increase workload and make models harder to manage. Conversely, a model without essential information cannot support decisions. Balancing the two helps focus resources on what adds value to the project.
