In infrastructure construction projects, stakeholder alignment is an important factor that contributes to project success and prevents excessive delays. Literature shows that it is known how to align stakeholders and what to do, however, when to carry out those actions, it not yet clear. This research contributes to that knowledge gap by analysing the Landside Infrastructure project of Schiphol as a single case study. Interviews with project stakeholders, project documents and field observations were used to collect data in order to develop a model.
