9-11. A steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $25,000 and would make the overpass adequate for an additional 6 years of service. If the overpass is torn down now, the scrap value of the steel would exceed the removal cost by $15,000. If it is reinforced, it is estimated that its net salvage (market) value would be $18,000 at the time it is retired from service. A new pre-stressed 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 8% per year and that the state pays no taxes. What would you recommend? (9.4, 9.7)
