Globalization is the process of integration among people, companies, and governments worldwide. It leads to increasing connectivity and interdependence of different parts of the modern world. Moreover, the process of globalization influences the construction industry and its expansion. However, with these new processes, the complexity of construction projects is growing. Along with globalization, multiculturalism emerges, which manifests itself as a mixture of socially, culturally, ethically, and religiously diverse communities. The aim of this thesis is to analyze and explain multiculturalism, as well as how to manage a multicultural workforce in construction projects. This thesis therefore analyzes examples of multicultural workforce management across the world. Furthermore, it analyses the multicultural environment on construction sites in Croatia, based on eminent scientific research. The results of the analysis of multicultural teams indicate a lack of understanding of the problem, the presence of discrimination and a lack of guidelines for resolving conflicts. According to experiences from other countries, measures to manage a multicultural workforce have finally been proposed in order to increase the efficiency of construction teams.
