A steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $22,000 and would make the overpass adequate for an additional five years of service. If the overpass is torn down now, the scrap value of the steel would exceed the removal cost by $14,000. If it is reinforced, it is estimated that its net salvage (market) value would be $16,000 at the time it is retired from service. A new prestressed concrete overpass would cost $140,000 and would meet the foreseeable requirements of the next 40 years. Such a design would have no net scrap or MV. It is estimated that the annual expenses of the reinforced overpass would exceed those of the concrete overpass by $3,200. Assume that money costs the state 10% per year and that the state pays no taxes. What would you recommend?
