In recent years, not only the aging of human but also that of buildings has attracted attention as a social issue. For conducting daily checks and repairs to realize longer life of buildings, interest in method to carry out more properly and continuously updating of planned parts and equipment etc. than ever is increasing. For the purpose, it is generally required formulation and review of a long-term maintenance and cost plan. However, even if the plan is formulated, it is difficult to secure additional construction costs when the maintenance cost of repair, management etc. is higher than planned. In particular, ordinary repair costs required for small-scale breakdowns or daily repair are not taken into consideration in the long-term maintenance plan in many cases. As a result, the cost of carrying out large-scale conservation and renovation will be insufficient, and the possibility of postponement of repair and maintenance modification for longer life will increase.
Therefore, in this research, focusing on the management data of Ordinary repair cost, it aims to analyze the occurrence timing and the actual situation of the construction amount costs, further grasp the long-term trend.
At first, it constructs the organization method to analyze the management data of the Ordinary repairs collected and accumulated by a building maintenance company. Next, the management data is organized from the viewpoint of building use, facility size, etc., to calculate the Ordinary repair cost per unit area, and to grasp the transition of the Ordinary repair cost per years from construction to the repair time. Finally, at the Maebashi Institute of Technology, the influence of Ordinary repair costs on the planning conservation plan with the maintenance planning cost software used in many municipalities.
Analysis of Ordinary repair in this research revealed that its cost accounts for about 10% of the planned construction, so it has a non-negligible effect on the formulation of the conservation plan. In addition, there are differences in recurring repair expenses depending on the scale and use. The larger the scale is, the tendency is that Ordinary repair costs tend to be lower. On the other hand, compared to offices and commercial facilities, Ordinary repair costs tend to be lower than that of apartment and public facilities.
