one plan for every campus
LOD stage plan
Seven stages take a campus from a brief to a building in use. Each stage names the level of development the model must reach, and the decision that level supports.
seven stages
From brief to hand-over
| Stage | Level | Decision it supports | What the team delivers | Who signs |
|---|---|---|---|---|
| 1 Brief | none | Which campus type, for how many learners, on which site? | Campus type, learner number, site check against the site rules. | Campus owner |
| 2 Concept | LOD 100 | Do the modules fit the site, with routes and services? | Massing model of modules on the site, fire-service route and assembly area. | Design lead |
| 3 Layout | LOD 200 | Does every space meet its size and seat rule? | Model with coded generic elements, seat counts, exit routes and a first element list. | Design lead |
| 4 Design | LOD 300 | Can we approve the design and a first budget? | Exact sizes, materials, fire and acoustic ratings, and quantities from the model. | Design lead and licensed engineer |
| 5 Coordination | LOD 350 | Do structure, services and interiors fit together? | Linked discipline models, a closed clash list and fixing details. | BIM coordinator |
| 6 Fabrication | LOD 400 | Can the factory make it and the site assemble it? | Part marks, tolerances, transport sizes, the lift plan and the build programme. | Fabrication lead |
| 7 Hand-over | LOD 500 | Can the facility team run and maintain it? | As-built model checked on site, element list, certificate list and maintenance plan. | BIM manager and facility lead |
who models what, when
Level by element group
| Element group | Concept | Layout | Design | Coordination | Fabrication | Hand-over |
|---|---|---|---|---|---|---|
| Shell (CS-SH) | 100 | 200 | 300 | 350 | 400 | 500 |
| Interior (CS-IN) | not modelled | 200 | 300 | 350 | 350 | 500 |
| Furniture (CS-FU) | not modelled | 200 | 200 | 200 | 300 | 500 |
| Services (CS-SV) | 100 | 200 | 300 | 350 | 400 | 500 |
| Site and ground | 100 | 200 | 300 | 300 | 300 | 500 |
- Use the least detail that supports the decision of the stage. Furniture stays generic for most of the project because nothing is decided by its screws.
- An element never states a higher level than the facts it carries. A wall with no fire rating is not LOD 300, however well it is drawn.
- Each stage ends with a short check sheet. The model moves on only when the sheet has no open item.
ten checks
The check sheet
Use this sheet at the end of every stage. It is the same for a mobile unit and a flagship.
- Every element has a code from our library and a level of development.
- File names follow the pattern: campus, building, level, discipline, element code.
- Seat counts in the model match the space programme of the campus type.
- Two exit routes from every floor, each at least 0.9 m clear.
- Step-free route from the entrance to every public room and to an accessible washroom.
- Guard rails at least 1.1 m on every terrace and stair.
- Wet rooms show waterproofing turned up the wall to 1.5 m.
- No supplier, maker or person names anywhere in the model, the lists or the file names.
- Quantities in the element list come from the model, and one has been checked by hand.
- The climate annex for the site is named, and its three checks are answered.
Learning material, not a design or safety instruction. Real buildings are designed and signed off by licensed professionals under local rules.
