The adoption of new technologies requires people to work differently and adopt new ways of thinking. This, however, is complicated because social conventions in professional disciplines are deeply rooted and have a long history. An extreme case as an exemplar was studied to investigate social change in a maintenance network. With concepts from stewardship theory and entrepreneurship literature, the case study is used to develop a preliminary model for managing social change in maintenance networks. The model presented is a first attempt to link stewardship theory to the practice of maintenance management. It will be refined and validated in future research and can complement other theories, such as agency theory and transaction cost economics, in explaining socio-technical phenomena in construction management. The practical contribution of this research to the construction management field is that it deepens our understanding of the clients’ leadership role.
