Construction projects involving large-scale educational buildings are highly prone to occupational accidents due to the hazardous nature of the work and inconsistent implementation of safety protocols. This study aims to identify and rank the most critical risk factors contributing to work accidents in the construction of the CWI-02 Package Building at ITS Surabaya. Using a mixed-method approach, primary data were collected through questionnaires, interviews, and field surveys involving 30 respondents, including contractor staff, supervisors, and supervisory personnel. The Risk Breakdown Structure (RBS) method was applied to quantify the probability and impact of each risk factor, enabling a structured risk prioritization. The analysis revealed three major high-risk contributors: labor indiscipline (risk value 0.690), refusal to use personal protective equipment (0.627), and the lack of clear standardization in Occupational Health and Safety (K3) implementation (0.577). These findings emphasize the urgent need for improved workforce discipline, enforcement of safety gear usage, and standardized safety management systems. The study provides actionable insights for project managers and policymakers to enhance construction site safety and mitigate accident risks in critical educational infrastructure projects.
