“…Literature review 2.1 PCs' quality issues Various quality issues have been reported in PCs' design, production, transportation and assembly processes; for example, the size of components could be inaccurate and lead to deviations in the position of a reserved hole (Li, 2020). In the construction of prefabricated joints, quality problems such as insufficient grouting and misalignment of the sleeves often occur (Duan and Li, 2019). Furthermore, the quality of PC involves more stakeholders than the conventional construction because of the dual production environments (the factory and site), more design work and prefabrication lead time, a longer error correction cycle and stricter requirements on dimensional accuracy (Luo et al, 2020a;Zhang and Yu, 2020).…”

PurposeThe quality liability of prefabricated components (PCs) is a major issue among key stakeholders. The blockchain-based quality tracking systems are supposed to support a more transparent and trusting quality control process. However, many factors affect the stakeholders' willingness toward the adoption of such quality tracking systems. The purpose of this research is to investigate the key factors that influence the stakeholders' adoption decisions toward the application of the quality tracking system in PCs and develop coping strategies.Design/methodology/approachAn evolutionary game model is established that includes the manufacturer, constructor and developer. Four scenarios of equilibriums and the game's evolutionary stable strategies are analyzed, and the corresponding stability conditions are then obtained. Based on the tripartite game model, two representative projects are used as case studies to simulate how different factors affect the stakeholders' decisions.FindingsFirst, trade-offs between cost and benefits were the most prominent factor in the adoption decision-making. Second, the advancement of technologies would compensate for their immaturity. Third, subsidy and penalty provision of the developer and high-level trust both incentivize the stakeholders to adopt the quality tracking systems.Originality/valueThis research investigates the influence of technology, environment and participant related factors on the adoption decisions of the quality tracking system for PCs and discovered that technology maturity and advancement played an essential role. It is expected that the research findings would be of value to policy makers and project management personnel for better quality control of prefabricated construction.
