Construction contracting is typically subjected to monitoring and control mechanisms. This policing contracting environment reflects the inherent distrust among the contracting parties. Paradoxically, construction project teams work best in a trusting environment because the members are mutually dependent on each other. Furthermore, where flexibility in performance is needed as in case of long-term or complex projects, trust is the necessary condition to suppress opportunism and avoid dispute.
