Abstract : Operational risks in road construction projects remain a major challenge affecting project performance, especially in developing regions with complex geographical conditions. This study aims to analyze operational risks related to labor and equipment, as well as formulate mitigation strategies based on ISO 31000:2018 for provincial road construction projects in Central Sulawesi, Indonesia. A mixed-method approach was used by combining qualitative and quantitative techniques. Primary data were collected through questionnaires, field observations, and semi-structured interviews with 40 respondents, including project managers, supervisors, safety officers, heavy equipment operators, and field workers. Secondary data were obtained from project reports, incident records, maintenance logs, and contract documents. Risk analysis was conducted using a risk matrix based on likelihood and consequence criteria from ISO 31000:2018. Research results indicate that labor-related risks—such as workplace accidents, physical fatigue, and non-compliance with personal protective equipment (PPE) use—remain significant operational issues affecting safety performance. Equipment-related risks, including equipment damage, downtime, non-compliance with preventive maintenance, and specification mismatches, also contribute to delays and reduced productivity. Validity and reliability tests confirmed that all research instruments are statistically acceptable, with Cronbach's Alpha values ranging from 0.785 to 0.876. The study further shows that preventive maintenance systems, competency-based safety training, stricter monitoring of PPE usage, and the integration of risk management into daily operational planning are effective mitigation strategies to reduce operational risks. This research contributes to the practical implementation of ISO 31000:2018 in road construction management and provides recommendations to improve work safety, operational efficiency, as well as the overall sustainability of project performance.
