The study's findings, which take a comprehensive look at risks during girder operation initiation in high-speed rail projects, are particularly relevant for structural integrity, project schedule, project safety, and the project's economics. The study is a mixed methods research that includes qualitative, descriptive statements from experts and cases and quantitative assessment of frequency, severity scales, and impact indicators. Structural & Engineering risks, Operational & logistical, Safety & Environmental and Financial & Project Management risks were systematically identified and categorized. The results indicate that structural risks, including loading estimates and misalignment, have the greatest severity because they can directly affect the integrity of the infrastructure. Safety measures were also born as critical, having to rely on strict adherence with the safety standards, as well as precautions against risks coming from the workers' accident and equipment failure. Operational risks identified included delays, mainly due to equipment unavailability and logistical issues affecting project timelines, which were more frequent. Commissioning risks, including cost overspending and budget mismanagement, were strongly associated with gaps in other risk areas. A comparison and contrast was also conducted, and it was shown that structural and safety risks are paramount in terms of mitigation strategies. The paper highlights the importance of developing an integrated risk management approach that integrates advanced engineering practices, resource planning efficiency, and proactive decision making.
