The UK construction industry is widely viewed as fragmented and diverse due to its project-based nature. According to Wild (2002), 80% of construction projects involve one-off clients and are non-recurrent. There is mounting pressure for construction to collaborate. The discourse of change towards collaboration espouse improved contracts, communications and management (Egan, 1998). The recommended change, however, remains aspirations of the policy makers (Wild, 2002). The inception, design, construction and operation of any construction project require the participation of various agents according to their professional knowledge, experience and their required input into the specific project. By nature of the diverse number of participants in construction, the delivery of projects requires collaboration by these participants. However, each constituency of participant or participants has its own agenda and interests. Each constituency of participants will mobilise its resources, knowledge and practices, as part of the project, to meet its interests. These interests are mainly financial to achieve a competitive edge over their competitors (Elmualim et al., 2006). Hence, there is a stringent need for collaboration between various organisations from architectural practices, consulting engineers, general contactors, specialised sub-contractors, to manufacturers and material suppliers as well as management firms in the delivery of construction projects. This intra-organisation collaboration is mirrored by an inter-organisational practice. It is argued that individual and organisational behaviour is highly influenced by national culture (Hofstede, 2001(Hofstede, , 2003. The conflict arises when an individual, an organisation or a group of individuals or organisations meet their own interest and ignore the interests of others. The dichotomy is that many firms and individuals while engaging in collaborative practices are seeking competition to advance their interests through competitive practices (Elmualim et al., 2006). Such practices of collaboration and competition at both levels of intra-or inter-organisations have caused the emergence of a culture of adversarial attitudes (Egan, 1998) that are pertinent within construction and decried by all (Green and May, 2003). The most compelling and pressing question is why organisations and individuals develop such paradoxical practices of competition and collaboration? And what are the implications of such behavioural traits on stakeholder management in construction? No doubt the role of culture and leadership to further advance mutually collaborative projects through stakeholder management needs no elaboration. To attempt to address these paramount questions requires adopting a multidisciplinary approach, particularly a psycho-socio structural approach that seek to understand culture and leadership and advance mutual relationships in construction through stakeholder management.
