Analysis and Identification of Building Construction Accident Risk in China basing Exclusively Database

In order to reduce the number of building construction accidents (BCA) and ensure construction activities safety, investigators analyzed BCA in China with recent representative 10 year data. Firstly, the investigators collected BCA information in the research period, determined accident trend and pattern in various dimensions. The development of safety management strategies for tower crane accidents (TCA) and collapse accidents (CA) was essential for construction safety control. Secondly, the investigators collected major construction accident (MCA) information in China in the research period, established AHP models for TCA and CA respectively. The second-level accident causes of the AHP model can provide targeted evaluation feedforward factors for quantitative checklist. Finally, the investigators formulated an audit method for TCA management measures and CA prevention management measures. It was found that there were specific trend and pattern in the occurrence of BCA, such as hourly trend, monthly trend, annual trend, regional pattern, type pattern, and cross pattern. Two MCA, TCA and CA, were screened out in this study. The corresponding feedforwards were obtained by analyzing the MCA.
