Recently, formulations to support decisions on the design and maintenance of bridges are based on the life-cycle cost assessment of alternative programs. In this paper, an approach to determine the optimal schedule for maintenance works for a typical bridge is described in a conceptual manner. The formulation considers the balance between safety and cost and both aspects are treated as random variables. The results may be used to target optimal scheduling for the tasks of preventive maintenance of a typical bridge.
