FIG. 1 is a diagram showing a configuration of a building maintenance management system according to an embodiment of the present invention. The building maintenance management system 1 according to the embodiment of the present invention includes a storage unit 11 and a control unit 14. The storage means 11 stores a three-dimensional architectural information model 12 and a building management ledger 13. Conventionally, visualization of a completed building drawing using a three-dimensional architectural information model 12 is known. The three-dimensional building information model 12 is composed of a three-dimensional shape of a building material model and an equipment model (hereinafter referred to as “building material / equipment model”) constituting the building, and a position and name in the building. It is a database, and the control means 14 can visualize the completed drawing of the building on the display means 3 based on the building material / equipment model.

  The display means 3 in FIG. 1 shows a completed drawing in which a building is visualized based on the three-dimensional architectural information model 12. The installer can check the exterior or interior of the building based on this completed drawing. In addition, because the tertiary picture architecture information model 12 is formed of a building material / equipment model composed of a three-dimensional shape, the inside and outside of the building are changed to different sizes and angles, or the inside of the building is It is possible to confirm by walking through.

  The building maintenance management system 1 according to the embodiment of the present invention uses a three-dimensional architectural information model 12 that has been used in the past to create a completed drawing, so that the user can easily understand the maintenance management of the building. It is to become. Therefore, the building management ledger 13 is stored in the storage unit 11. Based on the various information stored in the building management ledger 13, the control means 14 displays the building material / equipment model that requires maintenance management in the designated period on the display means 3 in a display form different from other building material / equipment models. One feature is to display.

  In particular, in this embodiment, the building management ledger 13 is not newly formed, but is formed on the basis of the three-dimensional building information model 12, thereby reducing the trouble for the user and accurately maintaining and managing the building. It is possible. Therefore, in the building maintenance management system 1 of the present embodiment, it is assumed that the capturing process for forming a part of the building management ledger 13 from the three-dimensional building information model 12 is executed.

  FIG. 2 shows an example of data immediately after the import processing from the three-dimensional building information model 12 to the building management ledger 13 is performed. The building management ledger immediately after the fetching process has a building material / equipment index, name, number of units, and installation location. The three-dimensional building information model 12 defines the three-dimensional shape, the position in the building, etc. of each building material model and equipment model. In this embodiment, when performing the capturing process, Integrated processing that handles all building material models and equipment models together. This is due to the fact that maintenance management is actually performed for each predetermined space. By performing this integration process, it is possible to simplify input of maintenance management, which will be described later. Note that the predetermined space used in the integration process is defined in correspondence with the space formed by the three-dimensional architectural information model by a program for executing the integration process or a separate table.

  For example, in the example of the air conditioner shown in FIG. 2, the integration process is performed for each room in a building. The air conditioner installed in the first floor A room (building material / equipment index: air conditioning-01) and the air conditioner installed in the first floor B room (building material / equipment index: air condition-02) are both 3 on the building management ledger. It can be seen that it is integrated into the table. The building material / equipment index on the building management ledger is identification information attached so that the building material model and the equipment model of the three-dimensional building information model 12 can be referred to. Due to the relationship between the two, when a building material and equipment are specified on the building management ledger, it is possible to specify the building material model and equipment model in the three-dimensional building information model 12 corresponding thereto.

The building maintenance management system of this embodiment forms a building management ledger by adding information necessary for maintenance management based on the information taken in from the three-dimensional building information model 12 as described above. FIG. 3 is a flowchart showing a building management ledger formation process according to the embodiment of the present invention. In the building management ledger formation process, further information is added to the various information fetched from the three-dimensional information model 12 described above. In this embodiment, the installation year, the service life (expiration date) input (S12), the consumable name input (S13), the management cost input (S13), and the management importance level input (S15) are executed. A building management ledger is formed.

  The installation year and the service life (S12) are information that defines the timing (lifetime) for performing management and maintenance on the actual building material and equipment corresponding to the building material / equipment model. For example, in the case of building materials and equipment having an installation year of 2013 and a useful life of two years, 2015 is the timing for management and maintenance of the building materials and equipment. In this embodiment, the information for specifying the timing of performing management and maintenance is specified separately for the installation year and the useful life, but in the building management ledger, the year when the useful life expires (the useful life) should be used. Is also possible.

  The consumable name (S13) is a name of a member that needs to be replaced or replenished particularly in equipment. For example, in an air conditioner, maintenance management is performed to replace the filter due to contamination of the filter. Here, the names of consumables are input in a form that associates the equipment and building materials that require replacement and replenishment with the equipment.

The management cost (S14) is an item that defines the cost required for maintenance management of building materials and equipment. In the present embodiment, the management cost of the consumable item name input in S13 is also input. The management cost refers to all the costs that are estimated to be necessary when performing maintenance management of each building material and equipment, and is calculated by the following calculation formula.
Management costs = (material costs + labor costs (existence of surcharge) + incidental construction costs + temporary costs) x number of units

  Here, the material cost is a material cost required for maintenance management of building materials and equipment. Labor costs are labor costs necessary for management and maintenance work. When night work and holiday work are necessary, labor costs are calculated in consideration of the extra work. Auxiliary construction costs are costs associated with management and maintenance work, such as opening and restoring ceilings and walls, and increasing security when exchanging, inspecting, and cleaning building materials and equipment. Temporary expenses are expenses incurred for various temporary facilities and places when performing maintenance work such as scaffolds, power supplies, electric lights, offices, and rest areas. By calculating the material cost, labor cost, incidental construction cost, and temporary cost for each unit, the management cost is calculated for each building / equipment index on the building management ledger.

The importance level classification (S15) is information indicating the importance of maintenance management for each building material and equipment. In the present embodiment, the degree of importance is expressed using a numerical value of 0 to 10. The importance classification can be determined for each building material and facility according to the criteria shown in (1) to (4).
(1) Great impact on human safety (2) Great impact on business continuity using buildings (3) Great impact in emergencies (earthquake, tsunami, flood, lightning strike, power outage, intrusion of suspicious individuals) (4) Important for building materials and equipment to be judged by adding and adding numerical values according to the degree of influence for each of these standards, which have a large impact on abnormal weather (abnormally high temperature, abnormally low temperature, strong wind, heavy rain, etc.) A degree classification is calculated.

FIG. 4 shows an example of the building management ledger 13 in which various information in S12 to S15 is input to the various information (FIG. 2) captured from the three-dimensional building information model 12 using the input means 2. Has been. In the figure, the portion surrounded by a broken line frame is information additionally inputted to the building management ledger 13 of FIG. For the air conditioner A and the air conditioner B, a pre-filter and a charcoal filter are added. These consumables are assigned the same building material / equipment index as the corresponding air conditioner A and air conditioner B, and can be handled in the same manner as the air conditioner A and air conditioner B. For each building material, equipment, and consumables, the installation year, useful life, management cost, and importance classification are additionally entered.

  Then, the building management process performed based on the building management ledger formed based on the three-dimensional building information model 12 in this way will be described. FIG. 5 is a flowchart showing building management processing according to the embodiment of the present invention. The building management process of the present embodiment is executed by the control unit 14 based on the three-dimensional building information model 12 and the building management ledger 13 stored in the storage unit 11 in the configuration of the building maintenance management system described in FIG. Process. Although the control means 14 can be configured by various computers, a program for executing building management processing by the control means 14 also belongs to the category of the present invention.

  As shown in FIG. 4, the building management ledger 13 is a database that prescribes the expiration date according to the installation year and the service life for each building material and equipment, and also specifies the management costs necessary for the service life. Based on the building management ledger 13, the building maintenance management system according to the present embodiment can make detailed the building materials and equipment that reach the end of their useful life in a specified period such as a specified year. It is important for the owner and manager of a building to understand the cost of the building. In this embodiment, by executing the building management process based on this building management ledger, it is possible to easily calculate and visualize the management costs required for building materials and equipment that will reach the end of their useful life in a specified period. It is said.

  In the building management process of this embodiment, the year from the start of management is adopted as the designated period, and in the management cost calculation process (S21), the management cost is calculated every year. The management costs for each year can be calculated by extracting the building materials and equipment that will reach the end of their useful lives in the designated year on the building management ledger shown in FIG. 4 and summing the management costs. In the building management process of this embodiment, the annual management cost calculated in the management cost calculation process is displayed on the display means 3 as a graph, so that the user can easily understand the transition of the management cost.

  FIG. 6 shows a graph showing the transition of the management cost according to the embodiment of the present invention. In the graph, the horizontal axis indicates the number of years elapsed from the management start year (0 years). The bar graph shows the management cost for each year, and one bar graph is displayed by being color-coded by work type. “Architecture”, “Electricity”, “Air conditioning”, “Hygiene”, “Elevator” are assigned as the work types. In this embodiment, each type of work is determined based on the type attached to the building material / equipment index in the building management ledger. In the example of FIG. 4, when the “outer wall” is attached to the building material / equipment index, the work type is determined as “building”, and when “air conditioning” is attached, the work type is determined as “air conditioning”. .

  Among the construction types, “architecture” is a management cost generated for a part related to the building structure of the building, such as a foundation, a structure, and an outer wall. “Electricity” is a management cost generated for the electrical system of the building. “Air conditioning” is a management cost incurred for a temperature and humidity adjustment system of a building such as an air conditioner. “Hygiene” is a management cost incurred for water receiving tanks, pumps and piping related to water supply and drainage. In addition, “elevator” is a management cost generated for facilities having an elevating structure such as an elevator, an escalator, a baggage elevator, and a mechanical parking lot. Further, in the graph of the present embodiment, the cumulative amount of management costs (right vertical axis display) is shown in a form in which black squares are connected.

As described above, in the present embodiment, when the management costs described in the building management ledger are classified by the designated period, it is possible to discriminate by the type of work, and the breakdown of the type of management cost by the user is easy to understand. It is possible to grasp. In this embodiment, graphs are displayed for each type of work, but the breakdown of management costs is not limited to the type of work classified here, but may be classified by another viewpoint or by a more detailed type. Good. In particular, by displaying the breakdown in the “importance level classification” described in the building management ledger, it is possible to allow the user to grasp the management costs that are essential in each designated year. Moreover, it is preferable that the breakdown type of these management costs can be switched by a user operation from the input means 2.

  During the building management process, in S23, a three-dimensional display of the building by the building material / equipment model is executed (S23). The three-dimensional display of this building is visualization of a completed drawing by a building material / equipment model that defines a conventionally known three-dimensional shape, as described in FIG. FIG. 7 shows an example of an output screen of the building maintenance management system according to the embodiment of the present invention.
