摘要
Key project stakeholders such as clients, consultant teams, contractors and workers have different sources of power to implement projects. How these powers influence health and safety risk management is not well documented. This article therefore assesses the perception and uses of stakeholders' power on health and safety in risk management in construction projects in Tanzania, specifically focuses on sources and types of power, how stakeholders perceive their power, how they use power on health and safety risk management, and what factors hinders their use of power. A case study strategy was adopted and four large on-going construction projects in Dar es Salaam Tanzania were involved. Data was collected through in-depth interviews with clients, consultants, contractors and construction workers. Findings indicate that stakeholders have different sources of power such as technical expertise, legitimate, political position, resources information to influence health and safety risk management. Nonetheless, the use of these powers was generally limited due to low level of knowledge on health and safety risk management among stakeholders, wrong perception on their roles, insufficient health and safety regulations and weak procurement system. The research recommends that, in order to realize health and safety performance through using stakeholder's power, there is a need of clear definition of stakeholders' role and responsibilities on health and safety, wide knowledge and experiences on health and safety risk management, strong regulatory system and procurement system.
