Construction Health & Safety Management And Maturity Evaluation For Working In Hot Weather

Heat stress, having caused preventable and lamentable deaths, is hazardous to construction workers in the hot and humid summers of Chongqing. Recently, a set of basic guidelines has been promulgated on site safety measures in hot weather as well as occupational health and safety management system being actively promoted. However, due to many practical problems, the present status of construction in hot weather is still very grim. Based on the theory of capacity maturity model, health and safety management maturity model (HSMMM) for working in hot weather is established with the aim to point the health and safety management capacity level, find the barriers and weak link so as to guide enterprises to improve their direction and goals, while raising the level of its management to provide the scientific method and means.According to the theoretical principles and modeling ideas of Capability Maturity Model (CMM), the evaluation indicator framework of Health and Safety Management Maturity Model for construction in hot weather is established. Based on relevant national laws, regulations and local policies, as well as research on health and safety management for working in hot weather from home and abroad, HSMMM evaluation system is built through expert scoring, membership grade analysis and correlation analysis.5 maturity levels and its meanings of HSMMM are defined, and 34 HSMMM evaluation factors are explicated. The proposed method of weighting the evaluation factors and the expression of evaluation performance provides a benchmark model and basis of evaluation for construction health and safety management for working in hot weather, moreover, it is pointed out the way and order management optimization. Guangsha Chongqing Construction Co., Ltd. is investigated as an empirical objective, through AHP evaluation method for quantitative assessment, various indicators maturity index and comprehensive maturity index is derived to assess the maturity of the enterprise level, and make recommendations for improvement.Questionnaire survey is conducted to construction managers from construction enterprises in Chongqing, and the current situation of health and safety management construction in hot weather is analyzed at a macro point of view. Hence, we can find the existing inadequacies that need to be strengthen and improved for construction enterprises in Chongqing. Capacity Maturity Model, a new concept for construction management, broadens the idea of construction health and safety management assessment in academic as well as enriches the application of evaluation tools, which provides platform for evaluation and improvement for health and safety management. HSMMM is bound to be as a targeted, efficient management capacity evaluation method and widely applied in construction industry.
