Exercise II: change management

Organize how changes to a design in the development and realization stages can be registered and processed in BIM. These changes may refer to:

  • Change to a property of a symbol (e.g. lengthening of a wall)
  • Change of the type of a symbol (e.g. change of family for a door)
  • Change in a relation between symbols (e.g. relocation of a door in a wall)
  • Change in a time property of a symbol (e.g. as a result of a scheduling change)

Organize the process of change management in both stages as a series of tasks that reflect the above types of changes and take into account possible causes of change, such as:

  • Changes in the brief (e.g. new activities added)
  • Changes in the budget (e.g. increase of façade cost necessitating reduction of cost elsewhere)
  • Changes in an aspect of the design (e.g. change in the heating solution or the fire rating of internal doors and ensuing interfacing issues – not just clash detection)
  • Changes in the construction schedules (e.g. due to delays in the delivery of components or to bad weather)
  • Errors in construction (e.g. wrong dimensioning or specifications of an element)


  1. Process and information diagrams, accompanied by short explanatory comments
  2. Basic model in a BIM editor demonstrating the way changes can be implemented
  3. Short overview of findings (two A4 sheets)


If the exercise is a group assignment, consider roles for the following aspects:

  • Process management
  • Information management
  • BIM modelling
  • Case analyses (for finding realistic examples)
