    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)
