An Examination on the Effectiveness and Practicality of New Reassessment Methods for Bridge Measures in Local Governments

Abstract

 Due to the lack of the budget and and other resources, it has become difficult and inefficient for local governments to repair all bridges classified under Health Condition Category III. Therefore, it is necessary to establish a new and efficient maintenance management method that can reduce repair costs and shorten project timelines. In this study, we introduced a new evaluation metric called the "Priority Action Value: K value" to conduct performance evaluations on bridges deemed to require detailed inspections. We proposed a new reevaluation method that reclassifies these bridges into categories such as repair, monitoring, obser vation, or reconsideration of health classification. The method is also preventing new bridges from transi tioning into this category. To establish this method, it is essential to determine the factors influencing the priority of measures (Kvalue), set detailed examination areas, define the detailed investigation methods and evaluation criteria for assessing loadbearing capacity and durability. One local government was tar geted to evaluate the effectiveness and practicality of the new method. As a result, the potential for visual izing the Kvalue and selecting bridges that require the detailed investigation was indicted. On the other hand, the need to reconsider the scoring ratio of Kvalues, the elements influencing their determination and the lines to determine the detaieled exmamination area was clarified.
