Social Risk Assessment and Management for Major Construction Projects in China Based on Fuzzy Integrated Analysis

With the vigorous development of major engineering projects in China, the social risks associated with major construction projects not only challenge the success of projects but also threaten social harmony and stability. Therefore, it is of great practical significance to assess and manage social risks. This paper aims to identify and evaluate the social risk factors by conducting a survey and assess the overall risk level of major construction projects (MCPs) with fuzzy integrated approach. First, 35 social risk factors and related stakeholders were identified based on literature analysis and case study. Then, 18 critical social risk factors (CSRFs) were selected and classified into six groups (CSRGs) based on a questionnaire survey. Next, using fuzzy integrated method, the probability of occurrence (PO), magnitude of impact (MI), the integrated risk level (IRL) of each CSRF and CSRG, and the overall risk of MCPs were calculated. As a result, "unfair compensation for housing demolition and land requisition" was the most critical social risk factor, and "policy/legal risk" was the most critical social risk group. The overall risk of MCPs was between moderate and high. At last, a social risk synthetic management framework was established, which can provide reference for policymakers and project decision makers to effectively manage the social risks.
