Abstract
Bridge is an indispensable facility as a social overhead capital. This study suggests and examines the ways of Economic valuation on maintenance alternatives for Bridge. In order to evaluate each alterative on the basis of the same time, the concepts of the basic year and the valuation year are introduced and applied. Interest rates and discount rates are also applied according to the time when each cost is incurred. This study also suggests the ways that the objects of the valuation on maintenance alternatives are not limited to construction cost, but the valuation period is fixed and so maintenance cost and remaining value incurred by maintenance alternatives are valuated. Furthermore, this study shows the way to estimate and evaluate maintenance cost through direct construction cost and annuity present value coefficient and the way to estimate remaining value based on the basic year. In addition, this study suggests economic valuation system, cost methods and analyses of the result through verification. The proposed system is considered to be applied to practical business.
