This paper proposes a process to predict the maintenance cost for the aging urban infrastructure and to manage the facilities reasonably by establishing the budget execution plan based on prediction. It is anticipated that preemptive maintenance will be possible through this, and it will be expected that the average performance grade of the facility will be improved and the management cost will be reduced through longevity improvement.
