Abstract：The construction industry is the most important pillar industry of China\'s national economy, and the quality of construction projects is the most important component of the construction industry. However, there are many uncertain factors in construction projects, and how to identify the key factors for quality control in construction projects and effectively manage them has always been a hot issue. This article conducts case analysis based on the specific characteristics of actual construction projects, identifies and summarizes the factors that affect the construction quality of the project through a combination of questionnaire surveys and expert interviews, and constructs a hierarchical model of project quality influencing factors. Among the comprehensive impact weights calculated using the AHP-DEMATEL model, the comprehensive impact weights of human quality (B2), construction organization design (E3), quality awareness (B3), and technical plan (E1) are relatively large, which are the key factors that have the greatest impact on the quality control process of the construction project. Furthermore, corresponding optimization measures were proposed for the quality control of the project in response to these key factors.
