Survey And Comprehensive Evaluation On The Health Of Construction Workers In Nanjing

Since the reform and opening up,with the rapid development of the construction industry,the national economy has made great achievements.However,over the years,the traditional construction production is too extensive,site management is often chaotic,resulting in a lot of environmental problems and waste problems.With the increasing shortage of environmental capacity,the country also attaches great importance to the industrial benefits of the construction industry,and the development of new building industrialization has been gradually put on the agenda.Serious health and safety problems in the construction industry not only reduce the economic benefits of enterprises,but also create a variety of social problems.Once a health and safety accident occurs on a project,it will cause delay and cost increase.The occurrence of health and safety accidents will also cause panic among other workers,which will reduce production efficiency and increase additional economic losses.Therefore,it is of great practical significance to study the occupational health of construction workers in order to guarantee the quality of construction projects and optimize project quality management and promote the effective and stable development of the construction industry.In this paper,the health-related factors of construction workers are systematically described,and the health-related indicators of construction workers are screened through literature review,and the relevant differences between the health of assembly construction workers and that of traditional construction workers are analyzed through case comparison.Health factors in determining the construction workers,after the establishment of index system for construction workers health effects,by studying the nanjing area prefabricated construction sites and traditional construction workers on the construction site occupational health status,and horizontal contrast to traditional construction and prefabricated construction site workers’ occupational health condition and impact factor of similarities and differences.Descriptive statistics and variance analysis were used to analyze the survey data,to explore the data differences among samples of traditional,prefabricated construction sites and component manufacturers,and the differences among samples of different types of work.Based on the data from the questionnaire survey,the structural equation model was established to explore the internal relationship between the factors influencing the occupational health of construction workers and their effects on work efficiency,taking the primary factors influencing the occupational health of construction workers and work efficiency as potential variables.Finally,the comprehensive evaluation model of construction workers’ occupational health was constructed by ANP method,which was mainly used to construct the index system weight,determine the weight value of each index,determine the evaluation criteria,and finally determine the comprehensive evaluation index and weight of construction workers’ occupational health.An example is given to verify the feasibility of comprehensive evaluation.
