BIM and LOD rules
What we ask of any designer or builder who works on an HFL campus, and how to learn it.
levels
Levels of development
A level of development says how much a model element can be trusted for a decision. Use the least detail that supports the decision.
| Level | Name | What the element carries | Campus use |
|---|---|---|---|
| LOD 100 | Concept | A symbol or a simple mass. Area and rough height only. | Site study: where do the modules fit, how many learners can we host. |
| LOD 200 | Generic | Approximate size, shape, position and a generic type. Uses our element code. | Layout and space programme. Check seat counts and routes. |
| LOD 300 | Precise | Exact size, shape and position, with the main material and fire rating. | Design approval and quantities for a first budget. |
| LOD 350 | Coordinated | Adds connections and fixings, so other trades can check clashes. | Coordination between structure, services and interior. |
| LOD 400 | Fabrication | Enough detail for the factory to make it and the site to assemble it. | Module shop drawings, stair and glass-wall fabrication. |
| LOD 500 | As built | What was really built, checked on site. | Handover to the facility team and the digital twin. |
information
Information every element carries
- Element code and name from our library (for example CS-IN-01).
- Fire rating, acoustic rating and finish.
- Supplier-neutral specification text: describe the performance, never a brand.
- Maintenance interval and expected life.
- Certificates held, and where the file is stored.
rules
Seven model rules
- Every model uses open file formats so any team can open it. Native files stay inside the team that made them.
- Names follow one pattern: campus, building, level, discipline, element code. Example: C01-B1-L2-ARC-CS-IN-01.
- One shared model environment holds the current, approved and archived versions. Nobody sends models by chat or mail.
- Each element lists a responsible author and the level of development it reached.
- Supplier and maker names never go into the model, the drawings, the schedules or the file names. A neutral description and our code are used instead.
- Quantities come from the model. A quantity that cannot be traced to the model is not accepted.
- Handover includes the as-built model, the element list, the certificate list and a maintenance plan.
