Communication is dynamic, social, challenging, and a key quality factor for construction projects. This is especially the case in multinational and inter-organizational infrastructure projects where factors like culture and language differ among the involved actors. As infrastructure projects usually extend over longer periods of time, collaborative relationships need to be established in which the actors can develop, for example, mutual understanding, learning, and efficient working routines. By building on empirical data from contemporary infrastructure projects, we explore how international contractors and a large public client communicate in multinational infrastructure projects (i.e., what the challenges are and what competences are needed). The analysis is based on the linguistic framework of communicative competence, and we contribute to the development of collaborative models in construction project management by suggesting the concept of contextual communicative competence.
