The recent bridge construction projects demand thorough and systematic safety and risk management, due to theincrease of risk factors following the introduction of new and complex construction methods and technologies. Amongmany types of damages that can occur in bridge construction projects, the damages to third parties who are notdirectly related to the existing property of the contractor construction project can also bring about critical loss in theproject in order to compensate the damages. Therefore, risks that could be caused by the loss occurred to indemnifythe third party damages should be clearly analyzed, although there are not subsequent amount of studies focusing onthe issue. Based on the past record of insurance payment from domestic insurance companies for bridge constructionprojects, this study aimed to analyze the risk factors of bridge construction for loss caused to compensate thethird-party damages happened in actual bridge construction projects and to develop a quantified and numericalpredictive loss model. In order to develop the model, the loss ratio was selected as the dependent variable; and amongmany analyzed independent variables, the superstructure, foundation, flood, and ranking of contractors were the foursignificant risk factor variables that affect the loss ratio. The results produced can be used as an essential guidancefor balanced risk assessment, supplementing the existing analysis on material losses in bridge construction projects bytaking into account the third-party damage and losses. |
