The Bouwteam is in both the building and infrastructure sector increasingly mentioned as a possibility to improve client-contractor collaboration. Currently, compared to the building sector, the infrastructure sector lags behind in applying this collaboration format. This research aims to investigate to what level building and infrastructure projects differ and match and whether differences in perspectives on collaboration are caused by the nature of sectors or influenced by other factors. The results of this research show that the nature of sectors is of little influence on the collaboration perspectives, while the relation between the client and contractor seems to have a major influence on the collaboration perspectives.
