Conflicts are an inevitable and very common occurrence in all types of human relationships, both private and business. As project teams are centered around the mutual work of project team members on a project, the relationships between team members also come into focus. Conflicts can have a positive but also a very negative impact on project teams. That is why it is very important to recognize conflict on time, know how to manage it and apply the appropriate tools to mitigate it so it does not have a negative impact on the success of the project. In the construction industry, projects are managed in a traditional way, the projects themselves are very expensive, long-term and extensive, so the expertise and mutual functioning of project team members are the key. The purpose of this paper is to investigate what are the main causes that lead to conflicts in the construction industry, what is their frequency and what are the consequences of conflicts, as well as which techniques are used to resolve those conflicts. In accordance with the presented theory on project management, conflicts in project teams and ways to resolve conflicts in project teams, an empirical study was conducted. Empirical research was conducted through an online questionnaire filled out by project managers and members of project teams in construction companies in the Republic of Croatia. The survey questionnaire was sent to 100 construction companies in the Republic of Croatia. The results of the research showed that in project teams in the construction industry, in most cases, conflicts are recognized at an early stages, they are resolved by the project manager and members of the project teams together, and that the techniques they use are successful.
