The issue of risk management in geodetic works for bridge construction projects is examined, which is relevant due to the high sensitivity of structural assembly accuracy to measurement errors and their impact on personnel safety. The study is based on the hypothesis that including the safety indicator S in the integrated risk index improves risk prioritization accuracy and ensures a preventive approach to management. The methodology is based on a modification of the MORAG method, supplemented with the safety criterion and an algorithm for calculating weighting coefficients using the Analytic Hierarchy Process (AHP). A quantitative risk analysis was conducted using data from five similar bridge construction projects. The results showed that the highest integrated risk (R = 0.342) is associated with the deviation in the position of structural supports, while the lowest (R = 0.087) is related to geodetic network inaccuracy. The proposed approach aligns with international standards ISO 31000 and ISO/IEC 31010 and can be applied for planning and monitoring geodetic works in complex engineering projects.
