¿ä¾à2 The recent bridge construction projects is demanded more sophisticated risk management measures and lossforecasts to brace for risk losses from an increase in the trend of bridge construction. This study aims to analyze therisk factors that caused the loss of material in actual bridge construction and to develop a quantified predictive lossmodel, based on the past record of insurance payment by major domestic insurance companies for bridge constructionprojects. For the development of quantitative bridge construction loss model, the dependent variable was selected as theloss ratio, i.e., the ratio of insurance payout divided by the total project cost, while the independent variable adopted 1)Technical factors: superstructure type, foundation type, construction method, and bridge length 2) Natural hazards:typhoon and flood 3) Project information: construction period and total project cost. Among the selected independentvariables, superstructure type, construction method, and project period were shown to affect the ratio of bridgeconstruction losses. The results of this study can provide government agencies, bridge construction design andconstruction and insurance companies with the quantitative damage prediction and risk assessment services, using riskindicators and loss prediction functions derived from the findings of this study and can be used as a guideline forfuture basic bridge risk assessment development research.
