[0009] According to the above-described building quality analysis system, the quality of the work content of the construction process can be analyzed based on items from a variety of perspectives.

[0010] A building quality analysis method according to a third aspect of the present invention is a building quality analysis system according to the first or second aspect, in which the inspection result analysis unit outputs analysis results based on the predefined items as at least one of a graph and a table.

[0011] According to the above-described building quality analysis system, the analysis results can be easily understood.

[0012] A building quality analysis system according to a fourth aspect of the present invention is a building quality analysis system according to any one of the first to third aspects, wherein the standards include standards based on laws and regulations and standards not based on laws and regulations.

[0013] According to the above-described building quality analysis system, the quality of the work content of the construction process can be analyzed based on various standards.

[0014] A method for analyzing the quality of a building according to a fifth aspect of the present invention includes an analysis step in which a computer analyzes inspection results to determine whether the work content of construction processes at multiple construction sites conforms to standards based on pre-defined items.

[0015] According to the above-described building analysis method, the same effects as those of the building quality analysis system according to the first aspect can be obtained.

[0016] A building quality analysis program according to a sixth aspect of the present invention causes a computer to execute an analysis step of analyzing inspection results to determine whether the work content of construction processes at multiple construction sites complies with standards based on pre-defined items.

[0017] According to the building analysis program, the same effects as those of the building quality analysis system according to the first aspect can be obtained. [Effects of the Invention]

[0020] Hereinafter, a building quality analysis system according to one embodiment of the present invention will be described with reference to the drawings.

[0021] <1. Building quality analysis system> <1-1. Overall structure of the building quality analysis system> FIG. 1 is a schematic diagram of a building quality analysis system 10 (hereinafter referred to as "system 10") according to this embodiment. System 10 is configured to appropriately perform quality control of buildings by analyzing inspection results of work performed during the construction process by a contractor (hereinafter referred to as "builder") who undertakes the construction of the building. The entity that checks the analysis results is, for example, a general contractor (general controller), a construction company, a home builder, or a housing franchise headquarters. Examples of buildings include individual homes, multi-family homes, apartment complexes, buildings, commercial facilities, and public facilities. Examples of builders are general contractors, construction companies, or home builders that carry out construction work in-house. In the following, the entity that manages system 10 may be referred to as a system management company.

[0022] System 10 includes an operator terminal 20, an inspection terminal 30, an analytical terminal 40, an inspection server 50, and an analytical server 60. The operator terminal 20, the inspection terminal 30, the analytical terminal 40, the inspection server 50, and the analytical server 60 are communicatively connected via a network 100.

Communication between the operator terminal 20, the inspection terminal 30, the analytical terminal 40, the inspection server 50, and the analytical server 60 is via wireless or wired communication.

[0023] <1-2. Hardware configuration of worker terminals> The worker terminal 20 is operated, for example, at a construction site by the building owner of the building. The construction owner is, for example, a site supervisor. The worker terminal 20 is, for example, a tablet terminal, a smartphone, or a personal computer. If the worker terminal 20 is, for example, a personal computer, the worker terminal 20 may be installed in the office of the construction company. In this embodiment, the worker terminal 20 is a tablet terminal.

[0024] The worker terminal 20 has a storage unit 21 and a control unit 22. The storage unit 21 and the control unit 22 are connected to each other so as to be able to communicate with each other via a bus 23. The storage unit 21 is, for example, a flash memory, a hard disk, or a solid state drive. The control unit 22 includes, for example, a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc.

[0025] <1-3. Hardware configuration of the testing terminal> The inspection terminal 30 is operated by, for example, a quality control officer of the construction company, a designer, an inspector belonging to a third-party inspection company contracted by the construction company to inspect the work content of the construction process, or an inspector belonging to a system management company. In this embodiment, the inspection terminal 30 is operated by the quality control officer of the construction company. The inspection terminal 30 is, for example, a tablet terminal, a smartphone, or a personal computer. If the inspection terminal 30 is, for example, a personal computer, it is installed in the office where the quality control officer works. In this embodiment, the inspection terminal 30 is a smartphone. The inspection terminal 30 has a memory unit 31, a control unit 32, and a bus 33. The memory unit 31 and the control unit 32 are connected so as to be able to communicate with each other via the bus 33. The specific configurations and functions of the memory unit 31 and the control unit 32 are similar to those of the memory unit 21 and the control unit 22 of the worker terminal 20.

[0026] <1-4. Hardware configuration of the analysis terminal> The analytical terminal 40 is operated, for example, by a quality control officer of a construction company, a designer, an inspector belonging to a third-party inspection company, or an inspector belonging to a system management company. In this embodiment, the analytical terminal 40 is operated by a quality control officer of a construction company. The analytical terminal 40 is, for example, a tablet terminal, a smartphone, or a personal computer. If the analytical terminal 40 is, for example, a personal computer, the analytical terminal 40 is installed in the office where the quality control officer works. In this embodiment, the analytical terminal 40 is a personal computer. The analytical terminal 40 has a main body 41, an input device 42, and an output device 43.

[0027] The main body 41 has a storage unit 41A and a control unit 41B. The storage unit 41A and the control unit 41B are connected to each other so as to be able to communicate with each other via a bus 41C. The storage unit 41A is, for example, a hard disk or a solid state drive. The control unit 41B includes a CPU, RAM, ROM, etc.

[0028] The input device 42 is, for example, a keyboard, and is connected to the main body 41. The output device 43 is, for example, a liquid crystal display, and is connected to the main body 41 so as to receive signals output from the main body 41. Note that the main body 41, the input device 42, and the output device 43 may be integrated into one unit, like a notebook personal computer.

[0029] <1-5. Test Server Configuration> The inspection server 50 is, for example, a virtual server constructed on the cloud. For example, inspection results can be input to the inspection server 50 using inspection terminals 30 at construction sites across the country, allowing many inspection results to be managed collectively by the inspection server 50. The inspection server 50 includes a memory unit 51 and a control unit 52. The memory unit 51 stores one or more programs related to creating inspection standards (hereinafter referred to as "inspection standard program 51X"). The control unit 52 executes the inspection standard program 51X stored in the memory unit 51 in response to a request from the inspection terminal 30. When the control unit 52 executes the inspection standard program 51X, one or more function blocks are constructed in the inspection server 50.

[0030] The functional blocks configured by the control unit 52 of the inspection server 50 executing the inspection standard program 51X stored in the memory unit 51 include, for example, an inspection standard creation unit 52X. The inspection standard creation unit 52X creates standards for the work content of the construction process. In this embodiment, the standards include a first standard, a second standard, a third standard, and a fourth standard. The first standard is a standard based on laws and regulations. Examples of laws and regulations include the Building Standards Act and the Housing Defect Liability Act. The second standard, the third standard, and the fourth standard are standards not based on laws and regulations. The second standard is, for example, a standard established by a home builder to ensure the quality of the building. The third standard is, for example, a standard established by a builder's quality control officer to ensure the quality of the building. The fourth standard is, for example, a standard established by the Japan Housing Finance Agency to meet the standards required for the Flat 35 loan. Each of the first to fourth standards is one or more specific standards established depending on the work content of the construction process.

[0031] Whether the work content of the construction process complies with the first to fourth standards is inspected by a quality control manager of the construction company, etc. The inspection results of whether the work content of the construction process at multiple construction sites complies with the standards are stored in the memory unit 51 of the inspection server 50.

[0032] <1-6. Test Results> 2 shows an example of inspection results 200 stored in the storage unit 51. In this embodiment, the inspection results 200 are stored in a hierarchical structure of steps 210, major items 220, medium items 230, minor items 240, and details 250.

[0033] Step 210 is an item for selecting the construction process for the inspection results that you want to check. Major item 220 is an item for selecting the work location in the construction process selected in step 210. Medium item 230 is an item for selecting the inspection perspective for the work location selected in major item 220. Minor item 240 includes a heading and content. The heading is an item for selecting a specific standard set forth in the first, second, third, or fourth standard. The content is an item for checking the detailed content of the specific standard selected in the heading. Details 250 is an item for selecting materials related to the specific standard selected in minor item 240. Details 250 includes CAD drawing data related to the specific standard, case photos of passed examples, case photos of failed examples, conflicting standards, countermeasures, and avoidance methods, etc.

[0034] <1-7. Construction process implementation and inspection> FIG. 3 is a flowchart showing an example of the timing of construction process implementation and inspection implementation. In this embodiment, the construction process for which inspections are conducted includes the first process to the tenth process. The construction owner uses the worker terminal 20 to transmit a reservation for inspection of the work content of the construction process to the inspection server 50. Note that in this embodiment, the construction process for which inspections are conducted is the first process to the tenth process, but the number of construction process for which inspections are conducted can be selected as desired.

[0035] In step S11, before the start of the construction process, the construction owner uses the worker terminal 20 to send a reservation for the inspection of the first process to the inspection server 50. In step S12, the construction owner carries out the first process. In step S13, the construction company's quality control manager carries out the inspection of the first process.

[0036] In step S14, the builder's quality control officer uses the inspection terminal 30 to input the inspection results of the first process into the inspection server 50. If the work content of the first process does not conform to the standards, the work content of the first process is corrected after step S14 so that it conforms to the standards.

[0037] From step S15 onwards, the same operations as steps S11 to S14 are repeatedly carried out for each of the second to tenth steps.

[0038] <1-8. Analysis Server Configuration> The analytical server 60 shown in FIG. 1 is, for example, a virtual server constructed on the cloud. This allows the analytical terminal 40 to easily obtain the analysis results of the test results. The analytical server 60 includes a memory unit 61 and a control unit 62. The memory unit 61 stores one or more programs related to the analysis of the test results (hereinafter referred to as "analysis programs 61X"). The control unit 62 executes the analysis program 61X stored in the memory unit 61 in response to a request from the analytical terminal 40. When the control unit 62 executes the analysis program 61X, one or more functional blocks are constructed in the analytical server 60.

[0039] The functional blocks configured by the control unit 62 of the analytical server 60 executing the analysis program 61X stored in the memory unit 61 include, for example, an inspection result analysis unit 62X. The inspection result analysis unit 62X performs an inspection result analysis process that analyzes inspection results based on predefined items. For example, a construction company may have branches in each area, such as Kansai and Kanto. Therefore, even if the quality of the construction work performed by a branch responsible for one area meets the standard, the quality of the construction work performed by a branch responsible for another area may not meet the standard. Furthermore, even within the same branch, the quality of the construction work performed by the same client may or may not meet the standard. In the inspection result analysis process, the inspection result analysis unit 62X analyzes the inspection results based on predefined items from various perspectives.

[0040] In this embodiment, the predefined items include, for example, a first item, a second item, and a third item.

[0041] The first item is an item related to the entity that will check the analysis results of the inspection results. The entities that will check the analysis results of the inspection results include, for example, the construction company's manager, the construction company's on-site person in charge, the construction company's design person, the construction company's quality control person, the construction company's inspection person, the construction company's subcontractor, the third-party inspection manager, the third-party inspector, and the inspector of the system management company. The inspection result analysis unit 62X analyzes the inspection results according to the entity selected in the first item.

[0042] The second item is an item related to the day, month, or period when the construction work will be carried out. The inspection result analysis unit 62X analyzes the inspection results by the day, month, or period when the construction work selected in the second item will be carried out.

[0043] The third item is an item related to the target of the analysis results. The third item includes, for example, the site manager, designer, quality control manager, inspection manager, inspector from a third-party inspection company, inspector from a system management company, job type, performance evaluation, area, property, construction process, inspection item, and product version. The inspection result analysis unit 62X analyzes the inspection results for each target of the analysis selected in the third item. The areas in the third item include, for example, Northern Kanto, Kanto, Tohoku, Shinetsu-Hokuriku, Chubu, Kinki, Chugoku-Shikoku, and Kyushu.

[0044] By executing the inspection result analysis process, the inspection result analysis unit 62X can grasp, based on the contents selected in each of the first to third items, indicators such as the number of properties inspected, the number and trends of cases in which the work content of the construction process did not meet the standards (non-conforming cases), construction processes in which non-conforming cases are likely to occur, performance evaluation scores, and the number of unregistered design documents.

[0045] In the test result analysis process, test result analysis unit 62X outputs the analysis results based on predetermined items as at least one of a graph and a table. The graph and table output by test result analysis unit 62X are displayed, for example, on output device 43 (see FIG. 1) of analytical terminal 40.

[0046] Figure 4 is an example of a graph of inspection results. For example, Figure 4 shows a graph in which the construction company manager is selected in the first item, the month is selected in the second item, and the area is selected in the third item. In the example shown in Figure 4, the number of non-conformance cases for a given month is displayed by area in a bar graph.

[0047] Figure 5 is an example of an inspection result table. Figure 5 shows a table where, for example, a construction company manager is selected in the first field, a desired time period is selected in the second field, and an area is selected in the third field. The example shown in Figure 5 displays whether the building plan registration deadline was met by area. Negative integers in Figure 5 indicate the average number of days that a building plan was registered before the registration deadline in a given period. In the example shown in Figure 5, it can be seen that in the Northern Kanto region, floor plans were registered on average five days before the registration deadline in a given period. Positive integers in Figure 5 indicate the average number of days that a building plan was registered after the registration deadline in a given period. In the example shown in Figure 5, it can be seen that in the Kinki region, floor plans were registered on average five days after the registration deadline in a given period. Note that a "0" in Figure 5 indicates that a building plan was registered on the day of the registration deadline in a given period.

[0048] <1-9. Test result analysis processing> An example of a processing procedure for the test result analysis processing will be described with reference to FIG. Test result analysis unit 62X starts the test result analysis process based on a request input from analytical terminal 40, for example.

[0049] In step S21, analytical server 60 obtains the test results from testing server 50. In step S22, test result analysis unit 62X determines whether all of the first to third items have been selected. If the determination in step S22 is negative, test result analysis unit 62X repeatedly executes the determination in step S22. If the determination in step S22 is positive, test result analysis unit 62X executes step S23. In step S23 (analysis step), test result analysis unit 62X analyzes the test results based on the contents selected in the first to third items. In step S24, test result analysis unit 62X outputs the analysis results as at least one of a graph and a table.

[0050] <2. System Effects> According to the system 10 of this embodiment, the following effects can be obtained.

[0051] <2-1> Based on the inspection results at multiple construction sites, it is possible to analyze the quality of the work carried out in the construction process by a specific construction company, for example, thereby enabling appropriate quality control of buildings.

[0052] <2-2> The predefined items include the first to third items, so that the quality of the work content of the construction process can be analyzed based on items from various perspectives.

[0053] <2-3> The test result analysis unit 62X outputs the analysis results based on predefined items in the form of at least one of a graph and a table, so that the analysis results can be easily understood.

[0054] <2-4> The standards for inspecting the work content of the construction process include standards based on laws and regulations and standards that are not based on laws and regulations, so it is possible to analyze the quality of the work content of the construction process based on a variety of standards.

[0055] <3. Modifications> The above-described embodiments are examples of forms that the building quality analysis system, building quality analysis method, and building quality analysis program of the present invention may take, and are not intended to limit the forms. The building quality analysis system, building quality analysis method, and building quality analysis program of the present invention may take forms different from those exemplified in the embodiments. Examples include forms in which part of the configuration of the embodiments is replaced, modified, or omitted, or forms in which new configurations are added to the embodiments. Some examples of modified embodiments are shown below.

[0056] <3-1> In the above embodiment, the test result analysis unit 62X is constructed in a server different from the testing server 50, but the test result analysis unit 62X may be constructed in the testing server 50. In other words, the functions of the testing server 50 and the analytical server 60 may be realized by a single server.

[0057] <3-2> In the above embodiment, the inspection server 50 and the analytical server 60 are virtual servers constructed on the cloud, but the inspection server 50 and the analytical server 60 may also be physical servers. In this modification, the inspection server 50 and the analytical server 60 may or may not be connected to each other so that they can communicate with each other. If the inspection server 50 and the analytical server 60 are not connected to each other so that they can communicate with each other, the inspection results stored in the inspection server 50 are saved in an auxiliary storage device such as a USB flash memory or an SD memory card. The analytical server 60 executes the inspection result analysis process by obtaining the inspection results from the auxiliary storage device. [Explanation of symbols]
