Constructions have considerable revenue and stakeholder accountability implications. It is the aim of this research to identify and assess risks so as to apply the appropriate controls for an Indonesian construction project. Observation, interviewing, and staff meetings were employed in this research. Risk analysis was conducted by a safety practitioner and validated with 12 construction workers. Methods like Fuzzy Logic (FMEA and AHP), PLS-SEM, Kruskal-Wallis, and cluster analysis were used to provide precise scoring and classification. Fuzzy Logic accommodated the uncertainty of risks, and Fuzzy-AHP ranked the risks with criteria of injury, asset loss, reputation, and environment. It defines two medium-risk and four high-risk activities, with the highest risk being Activity 2 (wall painting) due to being at height. Job Safety Analysis provides particular mitigation in detail. The RPN score for wall painting was 526, with a Mean Squared Error of 507 and an overall coefficient of variation of 6%, showing high consensus. This integrated methodology reduces bias, maintains uncertainty, and provides tailored safety recommendations, a new approach not implemented in past research.
