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

1. Process and information diagrams, accompanied by short explanatory comments
2. Basic model of the lecture hall in a BIM editor
3. Schedules for classification, measurement, estimates and scheduling in BIM

Evaluation criteria

1. The process diagrams should:
   1. Make all actors, stakeholders and tasks explicit
   2. Include feedback loops in decision making
   3. Have no unnecessary bridges
2. The information diagrams should:
   1. Indicate how symbols relate to the necessary measurements and estimates
   2. Allow to detect how information is derived from primary data
3. The model in BIM should contain:
   1. All relevant symbols
   2. All necessary equipment
   3. 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)
