The brief
Organize the process of repainting all walls in a large lecture hall at a university. The walls are in good condition, so a single coat of pain suffices. The process therefore can be reduced to the following tasks:
- Make a model of the lecture hall in BIM using direct measurements and photographs
- Classify wall surfaces and their parts with respect to:
- Labour (e.g. painting parts narrower than 30 cm are more time consuming)
- Equipment (e.g. parts higher than 220 cm require scaffolding)
- Accessibility (e.g. parts behind radiators or other fixed obstacles are hard to reach and therefore also time consuming)
- Measure the wall surfaces
- Make cost estimates
- Make a time schedule in 4D BIM
Deliverables
- Process and information diagrams, accompanied by short explanatory comments
- Basic model of the lecture hall in a BIM editor
- Schedules for classification, measurement, estimates and scheduling in BIM
Evaluation criteria
- The process diagrams should:
- Make all actors, stakeholders and tasks explicit
- Include feedback loops in decision making
- Have no unnecessary bridges
- The information diagrams should:
- Indicate how symbols relate to the necessary measurements and estimates
- Allow to detect how information is derived from primary data
- The model in BIM should contain:
- All relevant symbols
- All necessary equipment
- The necessary subdivisions of surfaces with respect to labour (tip: these are often determined by relations between symbols, e.g. wall to scaffold height)
Roles
If the exercise is a group assignment, consider roles for the following aspects:
- Process management
- Information management
- BIM modelling (two or more people)
- Analyses in BIM (using schedules – two or more people)
