Description

Program, quality control system and business support method

[0001] The present invention relates to a program, a quality control system, and a business support method.

[0002] In recent years, CAD (Computer Aided Design), which realizes BIM (Building Information Modeling), has come to be used in the design of buildings. By utilizing BIM for buildings, work throughout the life cycle of a building, such as the design stage, construction stage, and operation and management stage, becomes more efficient.

[0003] For example, Patent Document 1 discloses a design support device that creates CAD drawings based on a BIM model of a building. The design support device disclosed in Patent Document 1 takes into consideration the operating range of the seismic isolation device and interference with other objects when creating CAD drawings of a building equipped with a seismic isolation device.

[0005] However, the prior art has a problem in that it does not fully utilize BIM throughout the life cycle of a building. For example, the prior art does not describe the use of BIM models to support quality control work related to construction.

[0006] An object of one aspect of the present invention is to provide a program that further supports quality control work related to construction.

[0007] One aspect of the present invention is a program that causes a computer that supports quality control work related to construction to execute a screen display procedure that displays a quality control screen to support the quality control work based on a BIM model that shows construction drawings, an input procedure that accepts input of quality control information from a user that operates the quality control screen, and an update procedure that updates the BIM model in accordance with the quality control information, wherein the quality control screen displays the construction status of inspection points set on the construction drawings based on the BIM model, progress management information registered in the BIM model, and the quality control information.

[0008] According to one aspect of the present invention, a program that further supports quality control work related to construction can be provided.

[0010] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In this specification and drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant description will be omitted.

[0011] [Embodiment] One embodiment of the present invention is a collaborative work support system that supports the design of a building. The collaborative work support system in this embodiment includes multiple work support systems that support each work performed in the life cycle of a building. The collaborative work support system in this embodiment also includes an information sharing system that provides shared information commonly used in each work to the multiple work support systems.

[0012] Each business support system can be used independently by inputting the necessary information, but it can also perform processing to support specific business operations based on a BIM model that holds information generated in a previous process, or information generated based on a BIM model.

[0013] A BIM model is a model having multiple objects including attribute information. The BIM model in this embodiment is a three-dimensional (solid) model, but by not including height information, a substantially two-dimensional (planar) model may be generated or used.

[0014] A BIM model of a building includes, for example, building structural objects such as beams, columns, walls, floors, and ceilings, as well as equipment objects such as air conditioning equipment, electrical equipment, sanitary equipment, piping, and wiring. Attribute information of a BIM model of a building is, for example, information about the shape, material, dimensions, or installation position of each object. In addition to these, the attribute information in this embodiment includes information used in the design stage, such as product information and price information, and information used in the construction stage, such as process management information, progress management information, and quality control information.

[0015] Each business support system receives a BIM model in which information generated in a previous process is registered in the attribute information of each object, or information generated based on the BIM model, from a business support system that supports a previous process. Each business support system performs a predetermined task based on the received BIM model or information generated based on the BIM model. Furthermore, each business support system generates a BIM model to be used by a business support system that supports a subsequent process by registering information generated in a predetermined task in the attribute information of each object.

[0016] Traditionally, BIM models of buildings were created in the design stage and utilized in the operation and management stage for use in each task in the building's life cycle. However, the life cycle of a building can be considered to begin not only from the design stage to the operation and management stage, but also from the estimation stage. In particular, when rebuilding or renovating a building that is currently in operation, utilizing a BIM model from the operation and management stage makes it possible to efficiently perform tasks in the estimation stage. Conventional technology does not allow the use of BIM models in the estimation stage, nor does it allow the use of BIM models from the estimation stage in the design stage.

[0017] The collaborative work support system in this embodiment aims to expand the scope of use of BIM models in the life cycle of a building and to make each work in the life cycle of a building more efficient.

[0018] <Overall Configuration of Collaborative Work Support System> The overall configuration of the collaborative work support system in this embodiment will be described below. Fig. 1 is a block diagram showing an example of the overall configuration of the collaborative work support system in this embodiment.

[0022] The automated design system 1 supports design work. The automated design system 1 is, for example, an information processing device such as a personal computer, a workstation, or a server. The design work is the work of designing a building based on the building's specification information. The design work includes creating design documents, creating materials to be submitted to the client or general contractor, and checking the deliverables of partner companies.

[0023] The automated design system 1 of this embodiment has a function of generating a BIM model showing a design drawing based on a BIM model of a building that has been constructed in the past. The automated design system 1 also has a function of automatically creating a design calculation document based on the BIM model. The automated design system 1 also has a function of automatically calculating greenhouse gas (CO2) emissions based on the BIM model. Furthermore, the automated design system 1 has a function of automatically selecting and arranging equipment to be installed in the building based on the BIM model. Equipment to be installed in the building includes, for example, air conditioning equipment, electrical equipment, sanitary equipment, etc.

[0024] The estimate support system 2 supports the estimate work. The estimate support system 2 is an information processing device such as a personal computer, a workstation, or a server. The estimate work is a work of creating an initial estimate of construction costs based on design information for a building. The initial estimate includes the types of materials and equipment to be used in the construction of the building, and approximate prices for material costs, labor costs, management costs, etc., involved in the construction of the building.

[0025] The estimate support system 2 of this embodiment generates a BIM model showing the structure and equipment of a building based on the building's design information and special specifications. The estimate support system 2 also has a function to create cost estimation information showing an initial estimate based on the BIM model. Furthermore, the estimate support system 2 has a function to create a 3D BIM model without height information based on 2D CAD drawings. The estimate support system 2 also has a function to recognize the specification information written in the paper special specifications using optical character recognition (OCR) or the like and reflect it in the BIM model.

[0026] The inquiry system 3 supports inquiry operations. The inquiry system 3 is an information processing device such as a personal computer, a workstation, or a server. The inquiry operation involves collecting proposal information for equipment to be installed in a building from equipment vendors and the like, and determining product information and price information for the equipment. The inquiry operation includes contacting equipment vendors and the like, receiving proposal information for the equipment, and comparing and evaluating the proposal information.

[0027] The inquiry system 3 of this embodiment has a function of acquiring vendor information from the core system 30 and transmitting a proposal request including cost estimation information to equipment vendors, etc. The proposal request is written in a standardized format. The proposal information input by the inquiry system 3 is also generated in a standardized format. The inquiry system 3 also has a function of evaluating the validity of the proposal information by comparing the proposal information received from equipment vendors, etc. with product information and price information from past construction projects.

[0028] The cost review system 4 supports cost review work. The cost review system 4 is an information processing device such as a personal computer, a workstation, or a server. The cost review work is a work of managing costs for estimating the construction costs of a building. The cost review work includes calculating a uniform cost based on costs from past construction projects. The uniform cost includes costs related to material costs such as materials or equipment, and costs related to labor costs such as work or management.

[0029] The cost analysis system 4 of this embodiment has a function of calculating a unified cost from the product information and price information determined by the inquiry system 3 by linking with the estimate system 20. The cost analysis system 4 also has a function of creating cost estimation information indicating a detailed estimate based on the BIM model.

[0030] The working drawing creation system 5 supports the working drawing creation work. The working drawing creation system 5 is an information processing device such as a personal computer, a workstation, or a server. The working drawing creation work is the work of creating working drawings from design drawings.

[0031] The working drawing creation system 5 of this embodiment has a function of generating a BIM model showing a working drawing based on the BIM model generated by the automatic design system 1 and the BIM model generated by the cost analysis system 4. Note that the BIM model generated by the cost analysis system 4 does not have information regarding height.

[0032] In other words, the BIM model generated by the cost analysis system 4 is a BIM model with no defined height (no information about height is obtained, and the height is set to 0, for example). The BIM model showing the construction drawing is a BIM model with information about height. The construction drawing creation system 5 also has an automatic routing function that optimizes the routes of various pipes. Furthermore, the construction drawing creation system 5 has a unit function that optimizes the location where each piece of equipment is installed within the building.

[0033] The process control system 6 supports the process control work. The process control system 6 is an information processing device such as a personal computer, a workstation, or a server. The process control work is a work to manage each process of building a building based on schedule information that indicates the ordering status of materials or equipment used in the construction, delivery date information, etc.

[0034] The process management system 6 of this embodiment has a function to generate a BIM model in which process information is registered in the attribute information of each object, based on the BIM model generated by the working drawing production system 5. The process management system 6 also has a function to generate a BIM model based on schedule information acquired from the centralized production system 40. Furthermore, the process management system 6 has a function to generate a process chart based on the BIM model and display it on a mobile information terminal such as a smartphone or tablet terminal.

[0035] The progress management system 7 supports progress management operations. The progress management system 7 is an information processing device such as a personal computer, a workstation, or a server. The progress management operations are operations for managing the progress status of each process in a construction project to build a building.

[0036] The progress management system 7 of this embodiment has a function of reflecting progress management information in the BIM model generated by the working drawing creation system 5. The progress management information includes information for identifying panoramic photographs (360-degree images) taken inside the building and any issues that need to be addressed. The progress management system 7 also generates a virtual space for the building based on the BIM model. The progress management system 7 has a function of displaying the virtual space for the building and the panoramic photograph in a comparable manner, allowing the progress of each process to be checked from a remote location.

[0037] The information for identifying the panoramic photograph is, for example, a uniform resource locator (URL) that indicates the electronic location of electronic data recording the panoramic photograph. The electronic data recording the panoramic photograph may be stored in a storage device such as the HDD 504 of the progress management system 7, or in a storage device such as the HDD 504 of the information sharing system 10.

[0038] The quality control system 8 supports quality control work related to construction. The quality control system 8 is an information processing device such as a personal computer, a workstation, or a server. The quality control work is a work to track the response status of tasks (items of concern) that occur in each process and manage the quality of the building.

[0039] The quality control system 8 of this embodiment has a function of reflecting quality control information in the BIM model generated by the working drawing creation system 5. The quality control information includes construction photos taken at the construction site, blackboard information indicating the completion of construction, an inspection list indicating inspection items, etc. The quality control system 8 also has a function of setting inspection points in the BIM model and registering quality control information for each inspection point.

[0040] Furthermore, the quality control system 8 has the function of displaying progress management information (e.g., panoramic photos and issues) and quality control information (e.g., construction photos and blackboard information) registered at each inspection point in a comparable manner based on the BIM model, allowing the quality of the building to be confirmed from a remote location.

[0041] The operation management system 9 supports operation management tasks. The operation management system 9 is an information processing device such as a personal computer, a workstation, or a server. The operation management tasks are tasks for maintaining and managing buildings that are in operation. The operation management tasks include monitoring, repair, and replacement of the structure and equipment of the building.

[0042] The operation management system 9 of this embodiment has a function of reflecting operation management information in the BIM model generated by the working drawing creation system 5. The operation management information includes identification information that identifies operation data, inspection data, maintenance data, etc. of equipment installed in a building. Operation data is data indicating the operating status that is constantly output by equipment. Inspection data is data indicating the results of inspections of the building's structure, equipment, etc. that are conducted periodically. Maintenance data is data indicating the history of repairs, replacements, etc. of the building's structure, equipment, etc.

[0043] The information for identifying the operation data, inspection data, or maintenance data is, for example, a URL indicating the electronic location of the electronic data recording each piece of data. The electronic data recording the operation data, inspection data, or maintenance data may be stored in a storage device such as the HDD 504 of the operation management system 9, or in a storage device such as the HDD 504 of the information sharing system 10.

[0044] The information sharing system 10 provides each business support system with shared information shared among the business support systems included in the collaborative business support system 100. The information sharing system 10 is an information processing device such as a personal computer, a workstation, or a server. The shared information includes a BIM model generated by the operation management system 9 and external information acquired from an external data source.

[0045] The external information includes past and current price information (material prices, labor costs, etc.), past and current weather information, etc. In response to a request from the business support system, the information sharing system 10 transmits the requested shared information to the business support system.

[0046] The user terminal 50 is an information processing terminal such as a personal computer, smartphone, or tablet terminal operated by a user who uses the collaborative work support system 100. In response to user operation, the user terminal 50 connects to a work support system included in the collaborative work support system 100 and requests processing related to a specified work via a screen provided by the work support system. The user terminal 50 also receives the results of processing related to the specified work from the work support system and outputs them to the user.

[0047] The user terminal 50 may be a single information processing terminal connected to all the business support systems, or may be a plurality of information processing terminals connected to each business support system.

[0048] When the collaborative work support system 100 includes multiple user terminals 50, the user terminals 50 may be located in the same facility or in different facilities. When different companies are responsible for each task, a user terminal 50 may be located in each company corresponding to each task.

[0055] The computer 500 in this embodiment has a CPU (Central Processing Unit) 501, a ROM (Read Only Memory) 502, a RAM (Random Access Memory) 503, a HDD (Hard Disk Drive) 504, an input device 505, a display device 506, a communication I / F (Interface) 507, and an external I / F 508.

[0056] The hardware components of the computer 500 are connected to one another via a bus line 509. The input device 505 and the display device 506 may be connected to an external I / F 508 for use.

[0057] The CPU 501 is a computing device that reads programs and data from a storage device such as the ROM 502 or the HDD 504 onto the RAM 503 and executes processing to realize overall control and functions of the computer 500. The computer 500 may have a GPU (Graphics Processing Unit) in addition to or instead of the CPU 501.

[0058] The ROM 502 is an example of a non-volatile semiconductor memory (storage device) that can retain programs and data even when the power is turned off. The ROM 502 functions as a main storage device that stores various programs, data, etc. required for the CPU 501 to execute various programs installed in storage devices such as the HDD 504. For example, the ROM 502 stores boot programs such as a Basic Input / Output System (BIOS) and an Extensible Firmware Interface (EFI) that are executed when the computer 500 starts up, as well as data such as OS (Operating System) settings and network settings.

[0059] The RAM 503 is an example of a volatile semiconductor memory (storage device) in which programs and data are erased when the power is turned off. The RAM 503 is, for example, a dynamic random access memory (DRAM) or a static random access memory (SRAM).

[0060] The HDD 504 is an example of a non-volatile storage device that stores programs and data. The programs and data stored in the HDD 504 include an OS, which is basic software that controls the entire computer 500, and applications that provide various functions on the OS. The computer 500 may also use a storage device that uses flash memory as a storage medium (for example, an SSD (Solid State Drive)).

[0061] The input device 505 is, for example, a touch panel, operation keys, buttons, a keyboard, a mouse, or a microphone for inputting sound data such as voice, which are used by the user to input various signals. The display device 506 is configured with a display such as a liquid crystal or organic EL (Electro-Luminescence) display for displaying a screen, or a speaker for outputting sound data such as voice, etc.

[0062] The communication I / F 507 is an interface that connects to the communication network N1 and allows the computer 500 to perform data communication. The external I / F 508 is an interface that interfaces with external devices such as a drive device 510.

[0063] The drive device 510 is a device for loading a recording medium 511. The recording medium 511 includes media that record information optically, electrically, or magnetically, such as a CD-ROM, a flexible disk, or a magneto-optical disk. The recording medium 511 may also be a semiconductor memory that records information electrically, such as a ROM or a flash memory. The computer 500 can read data from and / or write data to the recording medium 511 via the external I / F 508.

[0064] The various programs to be installed in the HDD 504 are installed, for example, by setting the distributed recording medium 511 in a drive device 510 connected to the external I / F 508 and reading the various programs recorded on the recording medium 511 by the drive device 510. The various programs to be installed in the HDD 504 may also be installed by being downloaded via the communication I / F 507 from a network different from the communication network N1.

[0065] <Data Flow of Collaborative Work Support System> A data flow of the collaborative work support system 100 in this embodiment will be described below. Fig. 3 is a block diagram showing an example of a data flow of the collaborative work support system in this embodiment.

[0066] The automated design system 1 receives building specification information from a user terminal 50. The automated design system 1 generates a BIM model (design BIM) that shows a design drawing of a building based on a BIM model (operational BIM) of a building constructed in the past and the building specification information. The operational BIM is generated by an operation management system 9 and stored in an information sharing system 10. The design BIM generated by the automated design system 1 is sent to a cost analysis system 4 and a working drawing creation system 5.

[0067] The estimate support system 2 receives design information and special specifications for a building from the user terminal 50. The estimate support system 2 generates a BIM model (initial estimate BIM) that shows the structure and equipment of the building based on operational BIMs for buildings constructed in the past and the design information and special specifications for the building. The initial estimate BIM generated by the estimate support system 2 is sent to the cost analysis system 4 and the working drawing creation system 5.

[0068] The inquiry system 3 receives vendor information and project information from the core system 30. The inquiry system 3 receives cost estimation information from the cost analysis system 4 and transmits a proposal request including the cost estimation information to equipment vendors, etc. The inquiry system 3 generates product information and price information based on the proposal information received from equipment vendors, etc. and sends it to the cost analysis system 4.

[0069] The cost analysis system 4 generates cost estimation information based on the initial estimate BIM generated by the estimate support system 2 and sends it to the quotation system 3. The cost analysis system 4 works in conjunction with the quotation system 20 to calculate a unified cost from the product information and price information determined by the quotation system 3.

[0070] The working drawing creation system 5 creates a BIM model (construction BIM) showing working drawings based on the design BIM created by the automatic design system 1 and the initial estimate BIM created by the estimate support system 2. The construction BIM created by the working drawing creation system 5 is sent to a process management system 6, a progress management system 7, a quality management system 8, and an operation management system 9.

[0071] The process management system 6 receives schedule information from the centralized production system 40. The process management system 6 registers the process information in the construction BIM created by the working drawing creation system 5. The construction BIM updated by the process management system 6 is sent to the progress management system 7.

[0072] Furthermore, the process management system 6 receives construction completion information from the quality management system 8. The construction completion information indicates the construction location where construction has been completed and the date and time when construction was completed. Upon receiving the construction completion information, the process management system 6 registers the construction completion information in the construction BIM.

[0073] The progress management system 7 receives the progress management information from the user terminal 50. The progress management system 7 registers the progress management information in the construction BIM generated by the working drawing creation system 5.

[0074] Furthermore, the progress management system 7 receives construction completion information indicating construction locations where construction has been completed from the quality management system 8. Upon receiving the construction completion information, the progress management system 7 registers the construction completion information in the construction BIM.

[0075] The quality control system 8 receives quality control information from the user terminal 50. The quality control system 8 registers the quality control information in the construction BIM generated by the working drawing creation system 5. If there is a construction location where construction has been completed, the quality control system 8 sends the construction completion information to the process control system 6 and the progress management system 7. When construction has been completed at all construction locations (i.e., when the building is completed), the construction BIM in which the quality control information has been registered by the quality control system 8 is sent to the operation management system 9.

[0076] The operation management system 9 receives operation management information (operation data, inspection data, or maintenance data) from the user terminal 50. The operation management system 9 registers the operation management information in a construction BIM related to a building in operation. The BIM model (operation BIM) in which the operation management information has been registered by the operation management system 9 is accumulated in the information sharing system 10.

[0077] <Functional Configuration of Collaborative Work Support System> The functional configuration of the collaborative work support system in this embodiment will be described.

[0078] <Functional Configuration of Automated Design System> Fig. 4 is a block diagram showing an example of the functional configuration of an automated design system according to this embodiment. As shown in Fig. 4, the automated design system 1 according to this embodiment includes an input unit 11, an information acquisition unit 12, a business processing unit 13, a model generation unit 14, and an output unit 15.

[0079] The input unit 11, information acquisition unit 12, business processing unit 13, model generation unit 14, and output unit 15 are realized, for example, by processing that is executed by the CPU 501 of a program expanded from the HDD 504 shown in Figure 2 onto the RAM 503.

[0080] The input unit 11 accepts input of building specification information. The building specification information is data describing specifications that the building must meet, as required by the client. The input unit 11 accepts input of specification information by receiving the specification information from the user terminal 50.

[0081] The information acquisition unit 12 acquires an operational BIM from the information sharing system 10. The operational BIM is a BIM model related to a building that was constructed in the past. The operational BIM is generated by the operation management system 9 and stored in the information sharing system 10.

[0082] The business processing unit 13 displays a design screen for supporting design work on the user terminal 50. The business processing unit 13 executes processing related to the design work in response to a request from the user terminal 50. After executing processing related to the design work, the business processing unit 13 requests the model generation unit 14 to generate a design BIM.

At this time, the screen display unit 86 may further associate and display a panoramic photograph of the pre-construction state taken at the inspection point. That is, on the quality control screen displayed on the user terminal 50, the screen display unit 86 may extract the panoramic photograph from the progress management information registered in the attribute information of the object corresponding to the inspection point and display the construction photo and blackboard information and the panoramic photograph in a manner that allows comparison.

[0155] Furthermore, the screen display unit 86 displays the issues set on the construction drawings on a quality control screen displayed on the user terminal 50, as shown in Fig. 13, for example. Fig. 13 is a diagram showing an example of a quality control screen displaying issues. The quality control screen 171 shown in Fig. 13 displays an icon 172, such as a pin, near an object for which an issue has been registered.

[0156] Furthermore, the screen display unit 86 accepts a user operation to create a pointed out item from, for example, a quality control screen 171 shown in Fig. 13. When a user operation to specify a pointed out part is accepted, the business processing unit 83 displays a quality control screen 181 shown in Fig. 14 on the user terminal 50.

[0157] Fig. 14 is a diagram showing an example of a quality control screen for creating a pointed out item.

The icons 192a and 192b indicate the areas where the user has inputted suggestions. The icon 192b is a representative display to which information such as "x2" is added to indicate the number of overlapping icons.

[0162] The quality control screen 191 shown in Fig. 15 changes from a simplified display to a detailed display by zooming in. The quality control screen 191 shown in Fig. 15 also changes from a detailed display to a simplified display by zooming out. In the simplified display, when icons overlap in a certain area, a representative display is displayed, such as icon 192b, with information such as "x2" indicating the number of overlapping icons. In this way, the display of icons 192a and 192b on the quality control screen 191 changes in response to the zoom-in or zoom-out operation.

[0163] 15 may be able to switch between displaying a construction drawing as a 3D image or a 2D image. Also, the quality control screen 191 shown in Fig. 15 may be able to accept a user operation to rotate the 3D construction drawing and rotate and display the 3D construction drawing.

[0164] 15 includes a display / input field 193 for displaying and inputting information about the pointed-out portion for which the icon 192a is selected by a user operation. The screen display unit 86 may display information about the pointed-out portion for an icon selected from the icons 192a and 192b on the quality control screen 191 based on predetermined search criteria.

[0165] Furthermore, the screen display unit 86 can display a correction instruction sheet based on a user operation (e.g., one click) on the icon 182 displayed in Fig. 14, etc. The screen display unit 86 may display a correction instruction sheet creation button, and display or output (e.g., print) the correction instruction sheet based on a user operation on the correction instruction sheet creation button.

The correction instruction sheet shown in Figures 16 and 17 includes a list 201 of pointed out items, a floor plan 202 with icons indicating the pointed out locations, and details of each location 203 showing details of the pointed out locations.

[0167] The correction instruction forms shown in Figures 16 and 17 may be printable. A two-dimensional code indicating an input link may be printed on the printed correction instruction form in case the form is returned by hand from the contractor. Access to the correction instruction forms shown in Figures 16 and 17 may be controlled so that only the contractor's personnel can view the findings. The icons 182 displayed in Figure 14, for example, may be color-coded according to the importance of the findings (e.g., high, medium, low, etc.) and whether or not a consultation is required.

[0168] The business processing unit 83 may output various forms, reports, etc. to the quality control screen in response to user operations. The forms and reports are, for example, inspection forms, trial run reports, measurement reports, as-built drawings, etc. On the quality control screen, forms and reports are output in a format corresponding to each object included in the construction BIM. Since the construction BIM includes panoramic photos and construction photos, for example, it is possible to output forms and reports that include photos before and after construction for each inspection point.

[0169] Furthermore, the screen display unit 86 may print out a memo describing important points or points to be noted at the construction site. The memo describing important points or points to be noted at the construction site can be used to communicate with construction site workers who cannot use the user terminal 50, or as educational materials for personnel with little experience at construction sites.

[0170] The screen display unit 86 may output an inspection list in a format appropriate for each object included in the construction BIM. The inspection list is information that lists points that should be inspected for an object. A construction site manager or the like can efficiently perform inspections using a blank inspection list. The user performs quality control work by operating the quality control screens shown in FIGS. 13 to 17.

[0171] The model update unit 84 updates the construction BIM in response to a request from the business processing unit 83. The model update unit 84 updates the construction BIM by registering quality control information in the attribute information of each object included in the construction BIM. In addition, if there is a construction location where construction has been completed, the model update unit 84 registers construction completion information in the attribute information of each object included in the construction BIM.

[0172] The output unit 85 outputs construction completion information when construction is completed at any construction location. The construction completion information is sent to the process management system 6 and the progress management system 7. The output unit 85 outputs forms, reports, etc. based on the construction BIM updated by the model update unit 84.

[0173] Fig. 18 is a diagram showing an example of a report output. The report in Fig. 18 shows an example of an output of an inspection report 210. Data items that can be automatically input have already been entered in the inspection report 210. By using the inspection report 210, a user operating the user terminal 50 can easily create the inspection report 210.

[0174] <Functional Configuration of the Operation Management System> Fig. 19 is a block diagram showing an example of the functional configuration of the operation management system in this embodiment. As shown in Fig. 19, the operation management system 9 in this embodiment includes a model storage unit 91, an input unit 92, a business processing unit 93, a model update unit 94, and an output unit 95.

[0175] The model storage unit 91 is realized, for example, by the HDD 504 shown in Fig. 2. The input unit 92, the business processing unit 93, the model update unit 94, and the output unit 95 are realized, for example, by the CPU 501 executing a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503.

[0176] The model storage unit 91 stores an operational BIM. The operational BIM is a BIM model in which the operation management system 9 registers operation management information for the construction BIM updated by the quality management system 8.

[0177] The input unit 92 accepts input of operation management information. The operation management information includes operation data, inspection data, maintenance data, etc. The input unit 92 accepts input of operation management information by receiving the operation management information from the user terminal 50.

[0178] The business processing unit 93 displays an operation management screen for supporting operation management work on the user terminal 50. The business processing unit 93 executes processing related to the operation management work in response to a request from the user terminal 50. After executing processing related to the operation management work, the business processing unit 93 requests the model update unit 94 to update the operation BIM.

[0179] The model update unit 94 updates the operation BIM in response to a request from the business processing unit 93. The model update unit 94 updates the operation BIM by registering operation management information in the attribute information of each object included in the operation BIM. Therefore, the operation BIM stores history data such as operation data, inspection data, and maintenance data related to buildings currently in operation.

[0180] The output unit 95 outputs the operational BIM generated by the model update unit 94. The operational BIM is sent to the information sharing system 10.

[0181] <Functional Configuration of Information Sharing System> Fig. 20 is a block diagram showing an example of the functional configuration of the information sharing system 10 according to this embodiment. As shown in Fig. 20, the information sharing system 10 according to this embodiment includes a shared information storage unit 101 and an information providing unit 102.

[0182] The shared information storage unit 101 is realized, for example, by using the HDD 504 shown in Fig. 2. The information providing unit 102 is realized, for example, by a process that the CPU 501 executes by a program loaded from the HDD 504 to the RAM 503 shown in Fig. 2.

[0183] The shared information storage unit 101 stores in advance shared information shared among the business support systems included in the collaborative business support system 100. The shared information includes an operational BIM and external information. The external information includes past and current price information (material prices, labor costs, etc.), past and current weather information, etc.

[0184] The information providing unit 102 receives a request to acquire shared information from the business support system. The information providing unit 102 reads the shared information specified in the acquisition request from the shared information storage unit 101. The information providing unit 102 transmits the read shared information to the business support system that sent the acquisition request.

[0185] <Processing Procedure of Collaborative Work Support Method> A collaborative work support method executed by the collaborative work support system 100 in this embodiment will be described below. Fig. 21 is a flowchart showing an example of the collaborative work support method in this embodiment.

[0186] In step S1, the estimate support system 2 executes the process of the estimate support work in response to a request from the user terminal 50. Specifically, the estimate support system 2 receives the design information and special specifications of the building from the user terminal 50. Next, the estimate support system 2 generates an initial estimate BIM based on the operational BIM and the design information and special specifications of the building. The estimate support system 2 then sends the initial estimate BIM to the cost analysis system 4 and the working drawing creation system 5.

[0187] In step S2, the automatic design system 1 executes design work processing in response to a request from the user terminal 50. Specifically, the automatic design system 1 receives building specification information from the user terminal 50. Next, the automatic design system 1 generates a design BIM based on the operational BIM and the building specification information. The automatic design system 1 then sends the design BIM to the cost analysis system 4 and the working drawing creation system 5.

[0188] In step S3, the inquiry system 3 executes inquiry processing in response to a request from the user terminal 50. Specifically, the cost analysis system 4 receives the initial estimate BIM from the estimate support system 2. Next, the cost analysis system 4 generates cost estimation information based on the initial estimate BIM and sends it to the inquiry system 3.

[0189] The inquiry system 3 receives cost estimation information from the cost analysis system 4. Next, the inquiry system 3 receives vendor information and project information from the core system 30. Next, the inquiry system 3 transmits a proposal request including cost estimation information to equipment vendors, etc. Next, the inquiry system 3 receives proposal information from the equipment vendors, etc. Next, the inquiry system 3 generates product information and price information based on the proposal information. Then, the inquiry system 3 sends the product information and price information to the cost analysis system 4.

[0190] In step S4, the cost analysis system 4 executes processing of the cost analysis work in response to a request from the user terminal 50. Specifically, the cost analysis system 4 receives product information and price information from the inquiry system 3. Next, the cost analysis system 4 works in conjunction with the estimate system 20 to calculate a unified cost from the product information and price information.

[0191] In step S5, the collaborative work support system 100 determines whether or not an order has been received for the detailed estimate created up to step S4. If an order has been received (YES), the collaborative work support system 100 proceeds to step S6. If an order has not been received (NO), the collaborative work support system 100 ends the process.

[0192] In step S6, the working drawing production system 5 executes the processing of the working drawing production work in response to a request from the user terminal 50. Specifically, the working drawing production system 5 receives a design BIM from the automatic design system 1. The working drawing production system 5 also receives an initial estimate BIM from the estimate support system 2. Next, the working drawing production system 5 generates a construction BIM based on the design BIM and the initial estimate BIM. Next, the working drawing production system 5 sends the construction BIM to the process control system 6.

[0193] In step S7, the process management system 6 executes the process management work processing in response to a request from the user terminal 50. Specifically, the process management system 6 receives the construction BIM from the working drawing production system 5. The process management system 6 also receives schedule information from the centralized production system 40. Next, the process management system 6 updates and generates the construction BIM based on the construction BIM and the schedule information. Subsequently, the process management system 6 sends the construction BIM to the progress management system 7.

[0194] In step S8, the progress management system 7 executes the progress management work in response to a request from the user terminal 50. Specifically, the progress management system 7 receives the construction BIM from the process management system 6. Next, the progress management system 7 receives progress management information from the user terminal 50. Next, the progress management system 7 registers the progress management information in the construction BIM. Next, the progress management system 7 sends the construction BIM to the quality management system 8.

[0195] In step S9, the quality control system 8 executes quality control work processing in response to a request from the user terminal 50. Specifically, the quality control system 8 receives the construction BIM from the progress management system 7. The quality control system 8 also receives quality control information from the user terminal 50. Next, the quality control system 8 registers the quality control information in the construction BIM. Subsequently, if there is a construction area where construction has been completed, the quality control system 8 sends the construction completion information to the process management system 6 and the progress management system 7.

[0196] When the process control system 6 receives construction completion information from the quality control system 8, it registers the construction completion information in the construction BIM. When the progress control system 7 receives construction completion information from the quality control system 8, it registers the construction completion information in the construction BIM.

[0197] In step S10, the quality control system 8 determines whether the building is completed. If the building is completed (YES), the quality control system 8 sends the construction BIM to the operation management system 9 and proceeds to step S11. If the building is not completed (NO), the quality control system 8 returns the process to step S8.

[0198] In step S11, the operation management system 9 executes the processing of operation management tasks in response to a request from the user terminal 50. Specifically, the operation management system 9 receives the construction BIM from the quality management system 8. The operation management system 9 also receives operation management information from the user terminal 50. Next, the operation management system 9 registers the operation management information in the construction BIM. Then, the operation management system 9 sends the operation BIM to the information sharing system 10. The information sharing system 10 stores the operation BIM in the shared information storage unit 101.

[0199] In step S12, the collaboration work support system 100 determines whether or not to update (rebuild or renew) the building in operation. If the building is to be updated (YES), the collaboration work support system 100 returns the process to step S1 and starts the estimation work for the building update. If the building is not to be updated (NO), the collaboration work support system 100 ends the process.

[0200] The quality control work process shown in step S9 of Fig. 21 is performed, for example, according to the processing procedure shown in the flowchart of Fig. 22. Fig. 22 is a flowchart showing an example of the quality control work process.

[0201] In step S20, the quality control system 8 receives the construction BIM from the progress management system 7. Based on the construction BIM, the quality control system 8 displays, for example, a quality control screen for supporting quality control work shown in Figures 13 to 15.

[0202] The quality control screen displays the construction status (e.g., issues noted, confirmed, etc.) of inspection points set on the construction drawing based on the construction BIM, progress management information registered in the construction BIM, and quality control information registered in the construction BIM.

[0203] In step S22, the quality control system 8 accepts input of quality control information from the user terminal 50 that displays the quality control screen.

[0204] In step S24, the quality control system 8 updates the construction BIM with the quality control information received in step S22. In addition, if there is a construction location where construction has been completed, the quality control system 8 sends construction completion information to the process control system 6 and the progress control system 7.
