Knowledge sharing is indispensable for business organisations. The construction industry is one of the sectors in which intensive knowledge is spread across project-based teams. This study sheds light on which method is better for knowledge sharing within construction organisations: technology-based or face-to-face meetings. This research aims to understand organisational knowledge sharing by identifying and exploring the motivations and consequences of using face-to-face interaction vs. technology-based communication in project-based teams. This was undertaken through a qualitative case study with 15 employees of a large construction organisation. A qualitative analysis revealed four main factors related to worth adding a technology-based to face-to-face communication: the use of multiple communication strategies for knowledge sharing, whether sharing of all information via technology is allowed, legal restrictions, and limits on face-to-face communication due to work pressures. These findings contribute to the existing literature by identifying barriers and preferences regarding tools for sharing knowledge in a construction firm.
