Many infrastructure projects cope with a cost overrun and time delay due to the lack of effective design change management in case of design changes. To implement these design changes, an effective change process is necessary. This process guides the project team in identifying, documenting, evaluating and managing design change. With this technical tools are needed for implementation of change, namely BIM(Building Information Modelling). By using BIM, assessment is made on whether design changes are feasible and what consequences it may have on planning, costs, re-work, and clashes. However, current knowledge is lacking on how to use BIM when implementing a design change in a project. This research aims to set up a procedure that can be used by the project team for implementing design changes during the execution phase of infrastructural projects. To achieve this objective, the main research question is answered by analysing case studies. Hereby, both qualitative and quantitative analyses are carried out in three cases in the infrastructural field. Both analyses are subdivided into the organisational dimension(for the change process) and technical dimension(use of BIM). For the qualitative part, semi-structured interviews are held with contract managers and BIM managers. For the quantitative part, samples are taken to analyse each project. These samples consisted of all contractual changes in the project that led to a change in the design and which have been implemented after the execution phase has commenced. The results of the literature study and the case studies are used to develop a procedure to be used by the project team in case of design changes during the execution phase of infrastructural projects. By using this procedure, the project team gains a full understanding of how the design change process should proceed and which steps they have to take for effective implementation of design change with using BIM.
