Optimization path for construction safety resilience in megaprojects from the perspective of configuration

Construction safety has always been the key and focus of construction and management in megaprojects. Based on resilience theory and system theory, this study constructed an integrated analysis framework of construction safety resilience in megaprojects from the perspective of configuration. Qualitative comparative analysis (QCA) was used to analyse the configuration effect of multiple influencing factors on construction safety resilience in megaprojects of plateau and plain regions in China, and to explore the optimization path of construction safety resilience. The findings indicate that core drivers and optimization conditions for construction safety resilience in megaprojects are differentiated in the optimization paths for the two types of region. Moreover, megaprojects in the plateau regions are more focused on human capacity and require more technological tools to support safe construction than in the plain regions. The findings provide a theoretical basis and practical foundation for targeted optimization of construction safety resilience in plain and plateau megaprojects.
