This paper analyzes the actual costs of the repair work and the improvement work of which constitute the main portions of life-cycle cost. A complete enumerative study was made of the repair and improvement work costs of the 1,255 delivery post offices throughout Japan in 2000. This paper reports that the accumulative total of the repair and improvement work costs of some buildings tends to become higher than the total of the costs of each year of many buildings in a specific fiscal year, because it reflects the improvement work costs required by the change of demands in the years buildings were used.
