Whole life cost of post offices in Japan, based on a survey of actual conditions and consideration of investment correction

A complete enumerative study was made of the operating and maintenance costs of the 1,255 delivery post offices throughout Japan in 2000, in order to grasp the characteristics of the whole life costs of post office buildings. The operating and maintenance cost of five standard post offices were also monitored for 20 years. This paper demonstrates how the acquired knowledge of the whole life costs is used for the decision making of the facility investment. After analysing the relationship between the rebuilding cycle, and rebuilding, repair and improvement costs, by changing the present rebuilding at age 40 to building additions at age 40 and rebuilding at age 60, it became apparent that a significant reduction in facilities investment costs could be expected.
