This master thesis examined the role and impact of indi-viual and organizational culture differences as the cause of crises in construction projects. In a globalized world, it is very likely to be confronted with people and orga-nizations with a differing culture, which can lead to missunderstandings, conflicts and in the worst case to crises. Literature on culture, project management and crisis management was examined, and five interviews with project managers from the construction business were conducted. The study found that culture differnces can have a major impact on construction projects and on projects in general that led to crises in the surveyed pro-jects. It is therefore necessary to prepare for culture dif-ferences before entering a project. Especially an intercul-tural training and the selection of a culture sensitive pro-ject manager is recommended.
