Understanding key determinants of health climate in building construction projects

Health climate is critical for achieving a better health performance in building construction projects. However, the topic is rarely investigated by extant literature. The aim of this study is to identify key determinants of health climate in building construction projects. To achieve this goal, a hypothesis was established between practitioners' perceptions of health climate and their health status, based on a comprehensive literature review and structured interviews conducted with experienced experts. Then, a questionnaire was developed and administered for data collection. Partial least-squares structural equation modeling was used for data processing and hypothesis test. Results showed that health climate in building construction projects is positively correlated with the health status of the practitioners, and that employment involvement was the most important determinant of health climate in building construction projects, followed by management commitment, and supportive environment. Moreover, significant factors under each determinant of health climate were also disclosed. As limited research has been conducted to examine health climate in building construction projects, this study bridges the knowledge gap and is a contributory work to the current body of knowledge of construction health. Additionally, the findings of this study can provide authorities and practitioners with a deeper understanding of construction health and thereby helping them bring forward more feasible measures to improve health in building construction projects. Thus, this study is useful to the practice as well.
