Description

Process Control System

[0001] The present invention relates to a process control system.

[0002] CAD (Computer Aided Design) is used to realize BIM (Building Information Modeling) in the design of buildings. By utilizing BIM for buildings, it becomes possible to carry out work efficiently at each stage of the building's life cycle, such as the design stage, construction stage, and operation and management stage.

[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.

[0004] Japanese Patent Application Laid-Open No. 2020-201790

[0005] However, conventional technology has not fully utilized BIM throughout the life cycle of a building. For example, conventional technology generates a BIM model of a building during the design phase, but the BIM model is not utilized during the quotation phase. In particular, design companies, construction companies, construction management companies, construction companies, and operation management companies involved in construction have begun to utilize BIM, but software with functions tailored to each business is required.

[0006] In view of the above technical problems, one aspect of the present invention aims to provide a process management system that improves the efficiency of work carried out during the life cycle of a building.

[0007] A process management system according to one aspect of the present invention comprises an information acquisition unit that acquires a BIM model showing construction drawings of a building, and an operation processing unit that displays a process management screen for managing a process schedule created based on the BIM model.

[0008] According to one aspect of the present invention, a process management system can be provided that improves the efficiency of work carried out during the life cycle of a building.

[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 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 can also execute processes 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. A BIM model is a model that has multiple objects including attribute information. The BIM model in this embodiment is a three-dimensional model, but by not including height information, a substantially two-dimensional model may be generated or used.

[0013] In a BIM model of a building, objects include, for example, building structures such as beams, columns, walls, floors, and ceilings, as well as facilities such as air conditioning equipment, electrical equipment, sanitary equipment, piping, and wiring. In a BIM model of a building, attribute information is, for example, information about the shape, material, dimensions, and location of each object. In this embodiment, the attribute information also includes information used in the design phase, such as product information and price information, and information used in the construction phase, such as process management information, progress management information, and quality control information. Furthermore, a BIM model is assigned a project ID and a version ID that indicate the project as property information. Each object is assigned a unique external ID. The external ID is used, for example, to determine whether objects are identical when multiple collaborative work support systems are linked. Furthermore, the version ID is used to determine whether the update levels of each system are consistent.

[0014] 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 supporting a previous process, and performs a predetermined task based on the BIM model or information. Each business support system also generates a BIM model to be used by a business support system supporting a subsequent process by registering information generated in a predetermined task in the attribute information of each object. Each business support system can also access a cloud server on which a BIM model is stored to acquire the predetermined BIM model. In other words, each business collaboration support system can also operate independently. In this embodiment, the function of one business support system receiving a BIM model from another business support system can be interpreted as a function of accessing a cloud server on which a BIM model is stored to acquire the predetermined BIM model.

[0015] The process management system in this embodiment aims to make process management operations more efficient by creating a schedule based on a BIM model that is utilized throughout the life cycle of a building.

[0016] <Overall Configuration of Collaborative Work Support System> The overall configuration of the collaborative work support system in this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the overall configuration of the collaborative work support system.

[0017] As shown in FIG. 1 , the collaborative work support system 100 includes an automatic design system 1, an estimate support system 2, a quotation system 3, a cost review system 4, a construction drawing creation system 5, a process management system 6, a progress management system 7, a quality management system 8, an operation management system 9, and an information sharing system 10.

[0018] The collaborative business support system 100 in this embodiment is configured to be able to communicate data with the quotation system 20, the core system 30, the centralized production system 40, and the user terminal 50 via a communication network N1 such as a LAN (Local Area Network) or the Internet.

[0019] The automatic design system 1, estimate support system 2, inquiry system 3, cost analysis system 4, working drawing creation system 5, process management system 6, progress management system 7, quality control system 8, and operation management system 9 are examples of business support systems. In particular, the estimate support system 2 and the automatic design system 1 are examples of a first business support system. Furthermore, the inquiry system 3, cost analysis system 4, working drawing creation system 5, process management system 6, progress management system 7, quality control system 8, and operation management system 9 are examples of a second business support system.

[0020] The automated design system 1 is an information processing device such as a personal computer, workstation, or server that supports design work. The design work is the work of designing a building based on the building's specification information. The design work includes the creation of design documents, the creation of materials to be submitted to the client or general contractor, and the confirmation of deliverables from partner companies.

[0021] In this embodiment, the automated design system 1 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 a building based on the BIM model. Equipment includes, for example, air conditioning equipment, electrical equipment, sanitary equipment, etc.

[0022] The estimate support system 2 is an information processing device such as a personal computer, workstation, or server that supports estimate work. The estimate work is a work of creating an initial estimate of construction costs based on building design information. The initial estimate includes the types of materials, equipment, etc. used in the construction of the building, and approximate prices of material costs, labor costs, management costs, etc. involved in the construction of the building.

[0023] In this embodiment, the estimate support system 2 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 three-dimensional BIM model without height information based on two-dimensional 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.

[0024] The inquiry system 3 is an information processing device such as a personal computer, workstation, or server that supports inquiry operations. The inquiry operation involves collecting proposal information for equipment to be installed in a building from equipment vendors and determining product information and price information for the equipment. The inquiry operation includes contacting equipment vendors, receiving proposal information for the equipment, and comparing and evaluating the proposal information.

[0025] In this embodiment, the inquiry system 3 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, and 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.

[0026] The cost review system 4 is an information processing device such as a personal computer, workstation, or server that supports cost review work. 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 the costs of 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.

[0027] In this embodiment, the cost analysis system 4 has a function of calculating a unified cost from the product information and price information determined by the inquiry system 3 by cooperating 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.

[0028] The working drawing production system 5 is an information processing device such as a personal computer, a workstation, a server, etc. that supports the working drawing production work. The working drawing production work is the work of producing working drawings from design drawings.

[0029] In this embodiment, the working drawing creation system 5 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 about height. In other words, it is a BIM model with no specified height (no information about height is obtained, and for example, the height is set to 0), while the BIM model showing a working drawing is a BIM model with information about height. In addition, the working drawing creation system 5 has an automatic routing function that optimizes the routes of various piping. Furthermore, the working drawing creation system 5 has a unit function that optimizes the location where each facility or equipment is installed within a building.

[0030] The process control system 6 is an information processing device such as a personal computer, a workstation, or a server that supports process control work. The process control work is a work that manages each process of building a building based on schedule information that indicates the order status and delivery date information of materials or equipment used in the construction.

[0031] In this embodiment, the process management system 6 has a function of generating 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 of generating a BIM model based on schedule information acquired from the centralized production system 40. Furthermore, the process management system 6 has a function of generating a process chart based on the BIM model and displaying it on a mobile information terminal such as a smartphone or a tablet terminal.

[0032] The progress management system 7 is an information processing device such as a personal computer, a workstation, a server, etc. that supports progress management work. The progress management work is work that manages the progress status of each process in a construction project to build a building.

[0033] In this embodiment, the progress management system 7 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 has a function of generating a virtual space of the building based on the BIM model, displaying the virtual space and the panoramic photograph so that they can be compared, and enabling the progress of each process to be checked from a remote location.

[0034] 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.

[0035] The quality control system 8 is an information processing device such as a personal computer, a workstation, or a server that supports quality control operations. The quality control operations are operations that track the status of responses to tasks (indications) that arise in each process and manage the quality of the building.

[0036] In this embodiment, the quality control system 8 has a function of reflecting quality control information in the BIM model generated by the construction 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 at each inspection point. Furthermore, the quality control system 8 has a function of displaying progress management information (e.g., panoramic photos and findings) 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 remotely. Inspection points can be object-based or coordinate-based. Object-based inspection points inspect items specific to an object, such as equipment operation data or air volume at an air outlet. Coordinate-based inspection points can be set arbitrarily, such as to indicate a portion of a long object (e.g., the middle of a duct) or a portion of a floor or space, and can be set based on absolute coordinates in the BIM model.

[0037] The operation management system 9 is an information processing device such as a personal computer, workstation, or server that supports operation management work. The operation management work is the work of maintaining and managing a building in operation. The operation management work includes monitoring, repair, and replacement of the structure and equipment of the building.

[0038] In this embodiment, the operation management system 9 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. Operation data is data that indicates the operating status that is constantly output by equipment. Inspection data is data that indicates the results of inspections of the structure, equipment, etc. of a building that are conducted periodically. Maintenance data is data that indicates the history of repairs, replacements, etc. of the structure, equipment, etc. of a building.

[0039] 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.

[0040] The information sharing system 10 is an information processing device such as a personal computer, workstation, or server that provides shared information shared among the business support systems included in the collaborative business support system 100 to each business support system. The shared information includes a BIM model generated by the operation management system 9 and external information acquired from external data sources. 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 a business support system, the information sharing system 10 transmits the requested shared information to the business support system.

[0041] 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.

[0042] The user terminal 50 may be a single information processing terminal connected to all business support systems. The user terminal 50 may be multiple information processing terminals connected to each business support system. When the collaborative business support system 100 includes multiple user terminals 50, each user terminal 50 may be located within a single facility or in different facilities. For example, when different companies are responsible for each business, a user terminal 50 may be located within each company corresponding to each business.

[0043] 1 is an example, and various system configuration examples are possible depending on the application and purpose. For example, the collaborative work support system 100 may include multiple units of one or more of the automatic design system 1, estimate support system 2, inquiry system 3, cost analysis system 4, working drawing creation system 5, process control system 6, progress control system 7, quality control system 8, operation control system 9, and information sharing system 10.

[0044] For example, the automatic design system 1, the estimate support system 2, the quotation system 3, the cost analysis system 4, the construction drawing creation system 5, the process management system 6, the progress management system 7, the quality management system 8, the operation management system 9 or the information sharing system 10 may be realized by multiple computers or may be realized as a cloud computing service.

[0045] For example, the collaborative work support system 100 may include a standalone work support system that combines the functions of the automatic design system 1 and the working drawing preparation system 5, or the process control system 6, the progress control system 7, and the quality control system 8. The classification of devices such as the automatic design system 1, the estimate support system 2, the inquiry system 3, the cost analysis system 4, the working drawing preparation system 5, the process control system 6, the progress control system 7, the quality control system 8, the operation control system 9, and the information sharing system 10 shown in FIG. 1 is one example.

[0046] <Hardware Configuration of Collaborative Work Support System> The hardware configuration of each device included in the collaborative work support system 100 in this embodiment will be described with reference to FIG.

[0047] <<Hardware Configuration of Computer>> In this embodiment, the automatic design system 1, estimate support system 2, inquiry system 3, cost analysis system 4, working drawing creation system 5, process control system 6, progress control system 7, quality control system 8, operation control system 9, and information sharing system 10 are realized by, for example, a computer. Figure 2 is a block diagram showing an example of the hardware configuration of a computer.

[0048] 2, the computer 500 includes 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. The CPU 501, the ROM 502, and the RAM 503 form a so-called computer. The hardware components of the computer 500 are connected to each other via a bus line 509. The input device 505 and the display device 506 may be connected to the external I / F 508 for use.

[0049] 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.

[0050] 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 the HDD 504. Specifically, 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.

[0051] 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). The RAM 503 provides a working area in which various programs installed in the HDD 504 are expanded when executed by the CPU 501.

[0052] 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. Note that the computer 500 may use a storage device that uses flash memory as a storage medium (e.g., an SSD (Solid State Drive)) instead of the HDD 504.

[0053] The input device 505 includes a touch panel, operation keys and buttons, a keyboard and mouse, a microphone for inputting sound data such as voice, and the like, which are used by the user to input various signals.

[0054] The display device 506 is composed of a display such as a liquid crystal display or organic electroluminescence (EL) display for displaying a screen, a speaker for outputting sound data such as voice, and the like.

[0055] The communication I / F 507 is an interface that connects to a communication network and enables the computer 500 to perform data communication.

[0056] The external I / F 508 is an interface with external devices, such as a drive device 510.

[0057] The drive device 510 is a device for loading a recording medium 511. The recording medium 511 here includes media that record information optically, electrically, or magnetically, such as CD-ROMs, flexible disks, and magneto-optical disks. The recording medium 511 may also include semiconductor memories that record information electrically, such as ROMs and flash memories. This allows the computer 500 to read from and / or write to the recording medium 511 via the external I / F 508.

[0058] 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. Alternatively, the various programs to be installed in the HDD 504 may be installed by being downloaded via the communication I / F 507 from a network different from the communication network.

[0059] <Data Flow of Collaborative Work Support System> The data flow of the collaborative work support system 100 in this embodiment will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an example of the data flow of the collaborative work support system.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] <Functional Configuration of Collaborative Work Support System> The functional configuration of the collaborative work support system in this embodiment will be described with reference to FIGS. 4 to 34. FIG.

[0072] <Functional Configuration of Automated Design System> Fig. 4 is a block diagram showing an example of the functional configuration of the automated design system 1 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] The design screen presents the building specification information to the user. The design screen also creates a design calculation sheet based on the building specification information and presents it to the user. Furthermore, the design screen generates a two-dimensional CAD drawing based on the building specification information and automatically selects and arranges the equipment to be installed within the building.

[0078] The design screen also automatically calculates greenhouse gas (CO2) emissions based on the building's specifications and displays them to the user. Furthermore, the design screen also calculates the building's running costs based on the operational BIM and displays them to the user. This allows the user to efficiently proceed with the design while referring to the building's greenhouse gas emissions and running costs.

[0079] 5 to 7 show examples of design screens, in which a user operates the design screens shown in FIGS.

[0080] Various sources of building information are entered on the design screen shown in Figure 5. On the design screen, first, property settings are made. In property settings, outdoor air conditions, heat source system (chilled water temperature, hot water temperature, steam pressure), salt damage countermeasures, structural load (which side the exterior wall is on), humidification method, ventilation method, smoke exhaust method, etc. are set. Next, system settings are made. In system settings, the air conditioning system, air conditioning method (PAC, FCU), type (concealed, cassette, floor-mounted, built-in, ceiling-mounted), etc. are set. Next, room usage settings are made. In usage settings, settings such as office cubicles, offices, conference rooms, auditoriums, cafeterias, lobbies, and toilets are set.

[0081] As shown in Figure 6, when you select a range on the design screen, the settings are automatically made. The outdoor air conditions are based on a nationwide standard for cities called the Chahon, and the conditions are set by entering the city. The Chahon is the Building Equipment Design Standards: Ministry of Land, Infrastructure, Transport and Tourism, Minister's Secretariat, Government Buildings Department, Facilities.

[0082] The model generation unit 14 generates a design BIM in response to a request from the business processing unit 13. The model generation unit 14 generates the design BIM based on the specification information of the building and the operational BIM.

[0083] The model generation unit 14 includes BIM software. The model generation unit 14 creates a BIM model of a building based on a calculation model for which structural calculations have been performed in advance. The structural calculations are performed using structural calculation software. The calculation model (non-BIM model) used in the structural calculations is converted into a BIM model, thereby creating a BIM model after structural calculations.

[0084] The output unit 15 outputs the design BIM generated by the model generation unit 14. The design BIM is sent to the cost analysis system 4 and the working drawing creation system 5.

The operational BIM is generated by the operation management system 9 and stored in the information sharing system 10.

[0089] The business processing unit 23 displays an estimate screen for supporting the estimate work on the user terminal 50. The business processing unit 23 executes processing related to the estimate work in response to a request from the user terminal 50. After executing the processing related to the estimate work, the business processing unit 23 requests the model generation unit 24 to generate an initial estimate BIM.

[0090] The estimate screen presents a two-dimensional CAD drawing to the user. The estimate screen also edits the CAD drawing in response to user operations. The estimate screen then presents the CAD drawing in a manner that allows comparison with designs of buildings previously constructed based on the operational BIM. Furthermore, the estimate screen, in response to user operations, converts the edited two-dimensional CAD drawing into a BIM model without height information and presents it to the user. Converted members and components are displayed in 3D, while unconverted members and components are displayed as line drawings, which can be rotated and displayed in a single drawing for perspective viewing.

[0091] 9 to 12 are examples of quotation screens. A user performs a quotation job by operating the quotation screens as shown in FIGS.

[0092] The quotation screen recognizes and lists the lines on the floor plan and the symbols connected to them. It also models the parts on the list. It is also possible to switch between multiple special specifications (standard specifications, specifications for government agencies, etc.) to change all the components on the model at once and estimate the required materials for each specification.

[0093] The quotation screen allows you to model tees, crosses, straight pipes, 90° elbows, dampers, CAVs, and VAVs. Tees include those made up of short, perpendicular line segments, those at the intersection of a long and perpendicular line segment, and those with a block of tees made up of perpendicular line segments. Crosses include those made up of short, intersecting line segments, and those at the intersection of two long, intersecting line segments. 90° elbows include those made up of perpendicular line segments, those with a 90° elbow made up of line segments, and those with a block of 90° elbows.

[0094] The model generation unit 24 generates an initial estimate BIM in response to a request from the business processing unit 23. The model generation unit 24 generates the initial estimate BIM based on the design information, special specifications, and operational BIM of the building.

[0095] The output unit 25 outputs the initial estimate BIM generated by the model generation unit 24. The initial estimate BIM is sent to the cost analysis system 4 and the working drawing creation system 5.

[0096] <Functional Configuration of Inquiry System> Fig. 13 is a block diagram showing an example of the functional configuration of the inquiry system 3 in this embodiment. As shown in Fig. 13, the inquiry system 3 in this embodiment includes an input unit 31, an information acquisition unit 32, a business processing unit 33, and an output unit 35.

[0097] The input unit 31, information acquisition unit 32, business processing unit 33, and output unit 35 are realized by, for example, processing that is executed by the CPU 501 according to a program loaded from the HDD 504 shown in FIG. 2 onto the RAM 503.

[0098] The input unit 31 accepts input of cost estimation information indicating an initial estimate. The input unit 31 accepts input of cost estimation information by receiving the cost estimation information from the cost analysis system 4.

[0099] The information acquisition unit 32 acquires vendor information and project information. Vendor information is information about equipment vendors with which transactions can be made. Vendor information includes, for example, information indicating the contact information of the equipment vendor. Project information is information that records the results of past construction projects. Project information is, for example, information about the specifications and prices of equipment installed in a building. The information acquisition unit 32 acquires vendor information and project information by requesting the vendor information and project information from the core system 30.

[0100] The business processing unit 33 displays an inquiry screen for supporting the inquiry business on the user terminal 50. In response to a request from the user terminal 50, the business processing unit 33 executes processing related to the inquiry business.

[0101] The inquiry screen presents vendor information to the user. In addition, the inquiry screen sends a proposal request to an equipment vendor selected from the vendor information in response to a user operation. At this time, the inquiry screen describes the proposal request in a standardized format. As a result, the proposal information received from the equipment vendor is also written in a standardized format.

[0102] The inquiry screen also presents the user with proposal information received from equipment vendors, etc. At this time, the inquiry screen presents the proposal information in a manner that allows comparison with product information and price information from past construction projects. Furthermore, the inquiry screen selects the proposal information to be adopted in response to user operations. This generates product information and price information for the facility equipment.

[0103] 14 shows an example of an inquiry screen. A user operates the inquiry screen as shown in FIG. 14 to perform an inquiry operation.

[0104] The output unit 35 outputs the product information and price information generated by the business processing unit 33. The product information and price information are sent to the cost review system 4.

As shown in Fig. 15, the cost analysis system 4 in this embodiment includes a model storage unit 41, an input unit 42, a business processing unit 43, a model update unit 44, and an output unit 45.

[0106] The model storage unit 41 is realized, for example, by the HDD 504 shown in Fig. 2. The input unit 42, the business processing unit 43, the model update unit 44, and the output unit 45 are realized, for example, by a program loaded from the HDD 504 to the RAM 503 shown in Fig. 2 and executed by the CPU 501.

[0107] A design BIM and an initial estimate BIM are stored in the model storage unit 41. The design BIM is generated by the automatic design system 1 and sent to the cost analysis system 4. The initial estimate BIM is generated by the estimate support system 2 and sent to the cost analysis system 4.

[0108] The input unit 42 accepts input of product information and price information. The input unit 42 generates cost estimation information indicating an initial estimate based on the initial estimate BIM and transmits it to the inquiry system 3. The input unit 42 receives the product information and price information from the inquiry system 3, thereby acquiring the product information and price information.

[0109] Furthermore, the input unit 42 acquires price information and project information from the information sharing system 10. The input unit 42 acquires price information by requesting price information from the information sharing system 10. The input unit 42 acquires project information by requesting project information from the core system 30.

[0110] The business processing unit 43 displays a cost management screen for supporting the cost review work on the user terminal 50. In response to a request from the user terminal 50, the business processing unit 43 executes processing related to the cost review work.

[0111] The cost management screen presents product information and price information to the user. The cost management screen also presents proposal information in a manner that allows comparison with product information and price information from past construction projects. The cost management screen also calculates a unified cost based on current price information and presents it to the user. The cost management screen also determines the unified cost in response to user operations.

[0112] An example of a cost management screen is shown in Fig. 16. A user operates the cost management screen as shown in Fig. 16 to carry out a cost review operation.

[0113] The model update unit 44 updates the initial estimate BIM in response to a request from the business processing unit 43. The model update unit 44 updates the initial estimate BIM by registering product information and price information in the attribute information of each object included in the initial estimate BIM.

[0114] The model update unit 44 includes BIM software. The model update unit 44 creates an updated BIM model by editing attribute information of each object included in the BIM model before the update using the BIM software.

[0115] The output unit 45 outputs the unified cost based on the initial estimate BIM updated by the model update unit 44.

[0116] <Functional Configuration of Working Drawing Production System> Fig. 17 is a block diagram showing an example of the functional configuration of the working drawing production system 5 in this embodiment. As shown in Fig. 17, the working drawing production system 5 in this embodiment includes a model storage unit 51, a business processing unit 53, a model update unit 54, and an output unit 55.

[0117] The model storage unit 51 is realized, for example, by the HDD 504 shown in Fig. 2. The business processing unit 53, the model update unit 54, and the output unit 55 are realized, for example, by a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503, which is executed by the CPU 501.

[0118] The model storage unit 51 stores a design BIM and an initial estimate BIM. The design BIM is generated by the automatic design system 1 and sent to the working drawing production system 5. The initial estimate BIM is generated by the estimate support system 2 and sent to the working drawing production system 5.

[0119] The business processing unit 53 displays a working drawing creation screen for supporting the working drawing creation work on the user terminal 50. The business processing unit 53 executes processing related to the working drawing creation work in response to a request from the user terminal 50. When the business processing unit 53 executes processing related to the working drawing creation work, it requests the model update unit 54 to generate a construction BIM.

[0120] The working drawing creation screen generates two-dimensional CAD drawings based on the design BIM and presents them to the user. The working drawing creation screen also arranges equipment on the two-dimensional CAD drawings in response to user operations. The working drawing creation screen also arranges piping and other components connecting each piece of equipment on the two-dimensional CAD drawings in response to user operations. At this time, the working drawing creation screen automatically optimizes the layout of the equipment and the piping routes.

[0121] 18 to 22 are examples of working drawing creation screens. A user performs a working drawing creation task by operating the working drawing creation screens as exemplified in Fig. 18 to Fig. 22.

[0122] Figures 18 and 19 show the working drawing creation screens when performing automatic duct design. In automatic duct design, by clicking on the equipment's air outlet and the air outlet SA to the room, a connecting duct is automatically generated. Figures 20 to 22 show the working drawing creation screens when performing sleeve design. In sleeve design, by specifying the steel frame (beam) of the structural frame, the positions to drill holes in the steel frame are automatically designed.

[0123] The model update unit 54 generates a new design BIM and an initial estimate BIM from the two-dimensional CAD drawings edited on the construction drawing creation screen in response to a request from the business processing unit 53, and integrates them. As a result, a construction BIM is generated.

[0124] The output unit 55 outputs the construction BIM generated by the model update unit 54. The construction BIM is sent to the process management system 6 and the centralized production system 40. The centralized production system 40 manages the order status and delivery date information of materials, equipment, etc. used in the construction of the building based on the construction BIM, and generates schedule information.

[0125] <Functional Configuration of Process Control System> Fig. 23 is a block diagram showing an example of the functional configuration of the process control system 6 in this embodiment. As shown in Fig. 23, the process control system 6 in this embodiment includes a model storage unit 61, an information acquisition unit 62, a business processing unit 63, a model update unit 64, and an output unit 65.

[0126] The model storage unit 61 is realized, for example, by the HDD 504 shown in Fig. 2. The information acquisition unit 62, the business processing unit 63, the model update unit 64, and the output unit 65 are realized, for example, by a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503, which is executed by the CPU 501.

[0127] The model storage unit 61 stores a construction BIM. The construction BIM is generated by the construction drawing creation system 5 and sent to the process management system 6. The construction BIM may be a BIM model showing construction drawings for multiple construction sections. A construction section is an area separated by construction units. A construction section may be, for example, a building, floor, room, etc.

[0128] The information acquisition unit 62 acquires various information used in the process management work. Specifically, the information acquisition unit 62 acquires the construction BIM from the working drawing production system 5. The information acquisition unit 62 may acquire the construction BIM from a work support system other than the working drawing production system 5, an external server, or the like.

[0129] The information acquisition unit 62 acquires schedule information from the centralized production system 40. The schedule information is information that indicates the order status and delivery date information of materials or equipment used in construction. The schedule information may include schedules, labor rates, human resources, preliminary construction drawings, etc. created by each of multiple affiliated companies participating in the construction project.

[0130] The information acquisition unit 62 accepts input of progress management information. The progress management information is information indicating the progress status of each task. The information acquisition unit 62 may acquire the progress management information by receiving the progress management information transmitted by the progress management system 7. The progress management information is transmitted from the progress management system 7 when the progress status of each task changes.

[0131] The information acquisition unit 62 accepts input of construction completion information. The construction completion information is information indicating the construction location where construction has been completed and the date and time when construction was completed. The information acquisition unit 62 may acquire the construction completion information by receiving the construction completion information transmitted by the quality control system 8. The construction completion information is transmitted from the quality control system 8 when there is a construction location where construction has been completed.

[0132] The information acquisition unit 62 acquires various setting information designated by the user. The information acquisition unit 62 may acquire the setting information by receiving, from the user terminal 50, the setting information input by the user to the user terminal 50.

[0133] The setting information includes milestones. Milestones are intermediate goals that must be achieved in order to complete a construction project. Examples of milestones include the start date of power supply, the delivery date of large equipment, and safety inspections. Displaying milestones on the schedule makes it easier to determine the validity of the schedule.

[0134] The setting information includes holiday patterns. Holiday patterns are information that indicates the relationship between calendar information and non-working days. Holiday patterns can differ from site to site at a construction site. For example, some sites are closed on weekends and holidays, while others are closed only on Sundays. Setting holiday patterns for each site makes it possible to manage the process according to the specific circumstances of each site.

[0135] The setting information includes a correction coefficient. The correction coefficient is used to correct the length of a task. The line segment from the start point to the end point of a task is called a process line. The correction coefficient may be set according to the type of task or the attributes of the location where the task is performed. The standard correction coefficient is set to 1.0, and a larger value is set to make the task longer than the standard, and a smaller value is set to make the task shorter. For example, for a small, narrow room, the correction coefficient should be set smaller than the standard. On the other hand, for a large room, the correction coefficient should be set larger than the standard. Furthermore, for a high-rise floor, the correction coefficient should be set larger than the standard.

[0136] The correction coefficient may be set automatically based on information from the construction BIM. In that case, a message indicating that it has been automatically set is displayed. For example, the correction coefficient can be set based on the size, height, and convenience. For example, if the building is narrow, small, has many floors, or has few elevators, the correction coefficient may be set to a large value. For example, in the case of a property where the same pattern of work is repeated frequently, such as an apartment building, the correction coefficient may be set to a small value depending on the number of repetitions. The correction coefficient may also be set based on data other than the construction BIM. Examples of data other than the construction BIM include the number of workers available, busy periods, and material production status. Furthermore, since work efficiency decreases when a vacation spans the same task, even for the same task, the correction coefficient may be set differently depending on whether or not a vacation spans the task.

[0137] The business processing unit 63 generates a schedule showing each task of the building project based on the construction BIM and schedule information read from the model storage unit 61. When the construction BIM includes multiple work sections, the business processing unit 63 creates a schedule for each of the multiple work sections. Specifically, a schedule for the project name is created based on the project ID included in the BIM model information. The schedule is created hierarchically by assigning work sections based on information included in the attribute information, such as the building, wing, floor, and type of room on each floor. In addition, it can also be classified based on information included in the attribute information, such as the type of work (piping equipment, duct equipment, electrical equipment, etc.) and the business company in charge.

[0138] The business processing unit 63 displays a process management screen for supporting process management work on the user terminal 50. The business processing unit 63 executes processing related to the process management work in response to a request from the user terminal 50. After executing processing related to the process management work, the business processing unit 63 requests the model update unit 64 to update the construction BIM.

[0139] The process management screen displays a process schedule created based on the construction BIM and schedule information. The process management screen may display a preliminary design drawing, a construction schedule, a delivery schedule, a task list, etc. along with the process schedule. The preliminary design drawing is a diagram of advance considerations for carrying out construction safely and smoothly. The construction schedule is a diagram of the construction plan. The delivery schedule is a process schedule for delivering materials and equipment. The task list is a list of tasks related to the construction.

[0140] The process management screen may display, on the schedule, the milestones acquired by the information acquisition unit 62. The process management screen may display, on the schedule, non-working days according to the vacation pattern acquired by the information acquisition unit 62.

[0141] The process management screen may display the progress status of each task on the schedule based on the progress management information acquired by the information acquisition unit 62. The progress status may be, for example, a progress rate with construction completion being 100%. In this case, the process management screen may calculate the budget consumption rate along with the progress rate and display it on the schedule.

[0142] The process management screen may display progress using progress lines. Progress lines are broken lines that show the relationship between the progress of tasks. When progress lines are displayed on the process chart, it is easy to see whether each task is ahead or behind schedule as of the current day, allowing for efficient budget-to-actual management.

[0143] Fig. 24 shows an example of a process management screen. A user operates the process management screen as shown in Fig. 24 to perform a process management task.

[0144] FIG. 25 illustrates an example of a process management screen displaying milestones. As shown in FIG. 25, milestones and events can be entered separately from the process lines in the milestone row. They can be entered at the top to stand out with a thicker line than the process. Milestones can be created by double-clicking, entering information in the right panel, and pressing the "Save" button, just as when drawing a process line. Milestones are preferably displayed alongside each process line. Displaying them differently from the other process lines, for example, at a higher position or larger, can make them easier to see. Multiple types of milestones can be set, for example, based on user attributes or process type. This allows for easy viewing by changing the milestones displayed depending on, for example, whether the user is a manager or a worker, or which business company the user belongs to. Furthermore, by setting milestones based on the process type, only the process lines corresponding to the milestones can be displayed or the corresponding process lines can be highlighted. This makes it easy to make decisions, such as checking the progress of duct work for a duct inspection, or checking the progress of a specific work section for an inspection.

[0145] Figure 26 shows an example of the process management screen when applying a vacation pattern. As shown in Figure 26, with a vacation pattern selected in the left panel, click "Apply to Project" to apply the vacation pattern to the project. Multiple vacation patterns can be applied in combination. For example, templates are available for vacations by country or region of the project, or by business company, and these can be selected and combined as appropriate. Process lines can be set across vacations set by vacation patterns. Milestones are not based on information from the BIM model, but are set by the user.

[0146] Figure 27 is a diagram showing an example of the process management screen after applying a vacation pattern. As shown in Figure 27, the currently applied vacation pattern will have "Applied" displayed after the vacation pattern name. Press the "Cancel Project Application" button in the upper right corner. It is possible to apply multiple vacation patterns to one project.

[0147] 28 is a diagram showing an example of the process management screen in the initial state. As shown in Fig. 28, when the name of a process chart is clicked on the process chart list screen, the process chart screen is displayed. In the process management tab, it is possible to create processes in the process chart and input various additional information.

[0148] Figures 29 to 31 show examples of the process management screen when creating a schedule. As shown in Figure 29, click the "+Add" menu to add an item to the left panel (e.g., 1F, 2F, 3F). As shown in Figure 30, if subdivision is required, such as dividing work sections by floor, add a sub-level hierarchy by clicking the "Add Item to Sub-Level" menu under the "three-dot icon" on the right side of each item. As shown in Figure 31, this icon allows you to change the name, copy, paste, and delete rows. Tasks on multiple floors or work sections can be compared by sorting. This allows you to compare the progress of tasks, such as duct work, across work sections. This can be used for personnel allocation considerations and investigating the causes of delays.

[0149] Figure 32 shows an example of the process management screen when creating a process line. As shown in Figure 32, a process line can be created by clicking and dragging in the process chart area or by double-clicking in the process chart area. The process line setting items are displayed in the right panel, so enter the necessary information and press the "Save" button.

[0150] The General tab includes the project name, area, type / process, document, number of workers, number of working days, start date / end date / time, labor, BIM estimate, and link menu. The project name is the name displayed on the schedule line. The area is the item on which the schedule line is drawn. Change it only when you want to move it. The type / process is selected from the master information set in the Work Type / Family Settings tab. The number of workers is the number of workers. The number of working days is the number of days required for the work. The number of working days does not include project vacation days. The start date / end date / time are the start date / end date / time of the schedule line. Labor cost is calculated by multiplying the number of workers by the number of working days and displayed by pressing "Recalculate." The total labor cost can be automatically calculated without pressing "Recalculate." BIM estimate displays the total labor cost estimated from BIM information. The link menu allows you to set whether to link with the progress management system and quality management system. By entering the progress rate percentage, progress can be displayed in lightning line mode, as described below. Remarks allows you to enter remarks.

[0151] The business processing unit 63 determines the tasks to be included in the schedule based on each object included in the construction BIM. For objects that require multiple tasks, the business processing unit 63 determines the multiple tasks and sets their order. Requiring multiple tasks includes cases where multiple components are required to complete an object and cases where processing is required for a component. Specifically, this includes cases where accessories such as ducts are installed on equipment, or where thermal insulation is attached or applied to piping. This allows the elements and processes required to complete an object to be determined. In addition, the construction order may be determined based on the interference or positional relationship between objects. Specifically, when attaching objects to a structural frame (ceiling, floor, column), the object closest to the structural frame may be installed first, and the object farthest from the structural frame may be installed later. This prevents problems such as work being impossible. The order also includes the inspection process for the object. Specifically, ducts may be installed before inspection, or power may be connected to equipment before a trial run inspection. This prevents problems such as inspection being impossible.

[0152] The business processing unit 63 estimates the length of each task, i.e., the length of the process line, based on the number of workers indicated in the schedule information. The business processing unit 63 may correct the estimated length of each task based on a correction coefficient acquired by the information acquisition unit 62. The process management system 6 has a database that stores past process data. Specifically, the database stores information such as the type of building (e.g., condominium, hospital, factory, commercial facility), area, height, scale, construction site, number of workers, and actual required time. When making an estimate, the required time is estimated based on past data that is close to the conditions of the task being estimated (e.g., type of building, scale, number of workers). The business processing unit 63 may generate a preliminary design drawing, a construction process, a delivery process, a task list, etc., along with the process chart.

[0153] The business processing unit 63 edits the process schedule in response to a request from the user terminal 50. The business processing unit 63 may set or change the chronological order of each task included in the process schedule. The business processing unit 63 may add a new task to the process schedule. The business processing unit 63 may change the basic information of each task. The basic information of a task includes, for example, the work content, the number of workers, and the work period. For example, when the number of workers is changed, the length of the process changes, and the process schedule is updated to the extent that the chronological order set for each task is satisfied. For example, when the end point of one task is shifted, the process line of that task is extended, and the start point of another task that starts after the end of that task is also shifted at the same time.

[0154] When the model update unit 64 creates or edits a schedule, it updates the construction BIM stored in the model storage unit 61. The model update unit 64 updates the construction BIM by registering attribute information indicating a task in the attribute information of each object included in the construction BIM. Furthermore, when the model update unit 64 receives construction completion information, it registers the construction completion information in the attribute information of each object included in the construction BIM.

[0155] The output unit 65 outputs documents such as a schedule based on the construction BIM updated by the model update unit 64.

[0156] <Processing Procedure of Process Control Method> The process control method executed by the process control system 6 in this embodiment will be described with reference to Fig. 33. Fig. 33 is a flowchart showing an example of the process control method.

[0157] In step S101, the information acquisition unit 62 of the process management system 6 receives the construction BIM transmitted by the working drawing production system 5 or the construction BIM transmitted from an external server or the like in which a BIM model is stored. Next, the information acquisition unit 62 accepts input of the received construction BIM. Subsequently, the information acquisition unit 62 acquires schedule information from the centralized production system 40. Then, the information acquisition unit 62 stores the construction BIM and schedule information in the model storage unit 61.

[0158] In step S102, the information acquisition unit 62 of the process control system 6 receives the setting information input by the user to the user terminal 50. Next, the information acquisition unit 62 accepts the received setting information. The setting information includes milestones, vacation patterns, or correction coefficients. The information acquisition unit 62 does not need to acquire the setting information. In this case, a preset standard vacation pattern or correction coefficient is used. Note that the milestones may be included in the schedule information acquired in step S101, or may be determined based on the schedule information. The information acquisition unit 62 sends the acquired setting information to the business processing unit 63.

[0159] In step S103, the business processing unit 63 of the process management system 6 reads out the construction BIM and schedule information from the model storage unit 61. Next, the business processing unit 63 receives setting information from the information acquisition unit 62. Subsequently, the business processing unit 63 creates a schedule based on the construction BIM, schedule information, and setting information. If the construction BIM includes construction drawings for multiple work sections, the business processing unit 63 creates a schedule for each work section for each of the multiple work sections based on the construction drawings for each work section. The business processing unit 63 registers attribute information indicating tasks included in the created schedule in the construction BIM stored in the model storage unit 61.

[0160] In step S104, the business processing unit 63 of the process management system 6 reads out the construction BIM from the model storage unit 61. Next, the business processing unit 63 generates screen data for displaying a process management screen based on the construction BIM. The process schedule shown in the construction BIM is embedded in the screen data. The business processing unit 63 transmits the generated screen data to the user terminal 50. The user terminal 50 displays the process management screen based on the screen data received from the process management system 6.

[0161] In step S105, the business processing unit 63 of the process management system 6 edits the schedule in response to operations performed by the user on the user terminal 50. Operations for editing the schedule may include operations for adding new tasks, changing basic information about tasks, and setting the chronological relationship between tasks. After editing the schedule, the business processing unit 63 updates the attribute information of the construction BIM stored in the model storage unit 61 based on the edited tasks.

[0162] In step S106, the information acquisition unit 62 of the process management system 6 receives the progress management information transmitted by the progress management system 7. Next, the information acquisition unit 62 accepts input of the received progress management information. Subsequently, the information acquisition unit 62 registers the progress status of the construction BIM stored in the model storage unit 61 based on the accepted progress management information.

[0163] In step S107, the business processing unit 63 of the process management system 6 reads out the construction BIM in which the progress status is registered from the model storage unit 61. Next, the business processing unit 63 displays the progress status of each task on the schedule displayed on the process management screen based on the read-out construction BIM.

[0164] In step S108, the process control system 6 determines whether the construction is complete. Whether the construction is complete is determined based on the construction completion information received from the quality control system 8. If construction completion information has been received for all tasks included in the process schedule, the process control system 6 determines that the construction is complete. On the other hand, if construction completion information has not been received for any task included in the process schedule, the process control system 6 determines that the construction is not complete.

[0165] If the construction is complete (YES), the process control system 6 returns the process to step S106. On the other hand, if the construction is not complete (NO), the process control system 6 ends the process control method.

[0166] After returning to step S106, the process control system 6 repeatedly executes steps S106 to S108. Note that the process control system 6 may execute steps S102 and S105 at any timing in response to a user operation. In this way, the process control system 6 continues to manage the schedule and display the progress status until it is determined in step S108 that the construction is complete.

[0167] <Process Management Screen> The process management screen in this embodiment will be described with reference to FIGS.

[0168] Figure 34 is a diagram showing an example of a process management screen that displays a list of projects. As shown in Figure 34, when a user signs in, a list of projects is displayed. Click on the name of the project you want to display to move to the process schedule list screen. The process management system 6 can manage processes over a wide range across multiple projects (projects).

[0169] Figure 35 shows an example of a process control screen for configuring project settings. As shown in Figure 35, the "Work Type / Family" tab is clicked to display the settings screen. The left panel includes a group list and an add button. The group list displays applicable work type / family groups. The default group is a work type / family group that can be used for all projects. The add button creates a new work type / family group for the site. The main screen allows you to view the contents of the work type / family group selected in the left panel. The apply project button allows you to apply the work type / family group selected in the left panel to the project. Note that only one group may be applied per project. The duplicate and edit button allows you to duplicate the selected work type / family group for the project. The three-dot icon allows you to edit or delete the selected work type / family group. Note that editing and deletion may be disabled for template vacation patterns.

[0170] Figure 36 shows an example of the process management screen when linking a schedule to a construction section. As shown in Figure 36, after adding rows to the left panel, move to the "Area Linking" tab, select the space object to link to the row, and link it by dragging and dropping. Areas can be selected using the checkboxes in the list in the Linking Areas panel or by clicking in the BIM View panel. However, to select multiple areas in the BIM View, hold down the shift key while clicking. Once an area is selected, you can link it by dragging and dropping it from the Linking Areas panel to the target row in the left panel of the schedule. Area linking enables centralized management of primary information required for improving the accuracy of schedules and process management, such as automatic schedule calculation and external collaboration on construction progress and quality control status. When area linking is performed, an icon indicating linking is displayed on the right end of each row.

[0171] 37 is a diagram showing an example of a process management screen. As shown in FIG. 37, the process management screen 600 has a process chart area 601 and a work area area 602. The process chart area 601 includes a schedule display section 611, a process display section 612, and a milestone display section 613. The process management screen 600 further has an add button 621 and a progress display button 622.

[0172] The construction area area 602 displays a list of construction areas. The list of construction areas corresponds to multiple construction areas included in the construction BIM. When the user selects a construction area in the construction area area 602, a schedule created for that construction area is displayed in the schedule display section 612.

[0173] The schedule display section 611 displays calendar information. The calendar information is information indicating the dates of the period covered by the schedule. The dates may include the year, month, day, and day of the week. The schedule display section 611 may arrange the dates along a time axis along a predetermined axis. FIG. 37 shows the schedule display section 611 arranged from past dates to future dates from left to right.

[0174] The schedule display section 611 displays non-working days according to the holiday pattern. Figure 37 shows the schedule display section 611 with non-working days color-coded. Figure 37 shows an example where a holiday pattern has been set in which Saturdays, Sundays, and holidays are non-working days.

[0175] The process display section 612 displays each task 630 included in the process schedule. The tasks 630 are displayed as line segments indicating the work period of the task. The beginning of the task 630 indicates a planned start date 631 of the task 630. The end of the task 630 indicates a planned end date 632 of the task 630. The tasks 630 may be color-coded according to the type of task 630. Note that in FIG. 6, only representative tasks are labeled.

[0176] The process display unit 612 displays a context 633 of each task 630. The context 633 is displayed using a line type different from that of the task 630. For example, the task 630 may be displayed using a solid line, and the context 633 may be displayed using a dotted line. When the tasks 630 are connected using different line types, the user can easily understand the context between the tasks.

[0177] The process display unit 612 accepts an operation to set a chronological relationship between tasks 630. The operation to set a chronological relationship is an operation to select a preceding task and a succeeding task. In response to the operation to set a chronological relationship, the process management screen 600 adds a chronological relationship 633 connecting the preceding task and the succeeding task to the process display unit 612.

[0178] 38 to 40 are diagrams showing an example of a process management screen when creating a process line. As shown in Figures 38 to 40, by connecting process lines, the chronological relationship can be clearly expressed. Process lines can be connected by clicking and holding the red circle that appears when you place the mouse cursor on a process line and dragging it to the process line you want to connect.

[0179] The milestone display section 613 displays milestones by date. The milestone display section 613 may highlight milestones in bold or with a thick line. The milestone display section 613 is fixed near the schedule display section 611. In other words, the milestone display section 613 is displayed in a fixed position even when the process display section 612 is scrolled. Because the milestone display section 613 displays milestones together near the schedule display section 611, the user can check the process chart while comparing them with the milestones.

[0180] The add button 621 is a button for adding a new task to the process schedule. When the user presses the add button 621, the process display section 612 accepts an operation to add a task. The process management screen 600 adds the new task to the process display section 612 in response to the operation to add a task.

[0181] When a new task is added, the process management screen 600 displays an input area for inputting basic information about the task. When the user inputs the basic information about the task in the input area, the input content is reflected in the process chart.

[0182] The progress display button 622 is a button for switching whether or not to display the progress status in the process chart. When the user clicks the progress display button 622 while the progress status is displayed in the process chart, the process management screen 600 displays the progress rate of each task in the process display section 612. The process management screen 600 also displays a progress line in the process display section 612 based on the progress rate of each task.

[0183] <<Operation to Add a Task>> Fig. 41 is a diagram illustrating an example of the operation to add a task. As shown in Fig. 41 , the operation to add a task is, for example, an operation to click while positioning the mouse pointer P on a planned start date 631 in the process display section 612, and then drag the mouse pointer P to a planned end date 632. This adds a new task 630 whose work period is from the planned start date 631 to the planned end date 632.

[0184] <<Operation to Set a Preceding or Following Relationship>> FIG. 42 is a diagram illustrating an example of the operation for setting a preceding or following relationship. As shown in FIG. 42 , the operation for setting a preceding or following relationship is, for example, an operation for connecting the end of a preceding task 630A to the beginning of a following task 630B in the process display unit 612. Specifically, the operation involves clicking the mouse pointer P while it is positioned on the scheduled end date 632A of task 630A and dragging the mouse pointer P to the scheduled start date 631B of task 630B. Alternatively, the operation may involve clicking the mouse pointer P while it is positioned on the scheduled start date 631B of task 630B and dragging the mouse pointer P to the scheduled end date 632A of task 630A. This adds a preceding or following relationship 633 between task 630A and task 630B. When moving one of multiple tasks linked by a preceding or following relationship, the other linked tasks can also be set to move. It is also possible to prevent them from moving by setting them to not move.

[0185] When the mouse pointer P is near the task 630A, the process display unit 612 may notify the user that a context can be set by highlighting the scheduled end date 632A. For example, the process display unit 612 may highlight the scheduled end date 632A by changing the color and / or line type of the scheduled end date 632A.

[0186] <<Progression Lines>> Figure 43 is a diagram illustrating an example of a progress line. As shown in Figure 43, a progress line 700 indicates the relationship between the progress statuses of tasks. The progress line may be displayed by determining and storing the schedule of the task, and displaying the progress line for the amount of delay relative to the schedule. Specifically, the progress line 700 is a broken line formed by dividing the work period of each task 630A-630D in half based on the progress rate and connecting the division points 635A-635D.

[0187] The progress line 700 further includes a line segment extending vertically from the column 701 representing the current day in the schedule display section 611. Therefore, the progress line 700 allows easy visual confirmation of whether each task is ahead of or behind the progress rate planned for that day. Specifically, a task 630 whose division point 635 is further back (leftward) than the column 701 representing the current day indicates that it is behind schedule, while a task 630 whose division point 635 is further back (rightward) than the column 701 representing the current day indicates that it is ahead of schedule. In the example shown in FIG. 43 , it can be seen that task 630B is behind schedule and task 630D is ahead of schedule. The progress rate can be calculated by user input, but when linked to a progress management system, it is updated based on the progress rate % of each process received from the progress management system.

[0188] <Functional Configuration of Progress Management System> Fig. 44 is a block diagram showing an example of the functional configuration of the progress management system 7 in this embodiment. As shown in Fig. 44, the progress management system 7 in this embodiment includes a model storage unit 71, an input unit 72, a business processing unit 73, a model update unit 74, and an output unit 75.

[0189] The model storage unit 71 is realized, for example, by the HDD 504 shown in Fig. 2. The input unit 72, the business processing unit 73, the model update unit 74, and the output unit 75 are realized, for example, by a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503, which is executed by the CPU 501.

[0190] The model storage unit 71 stores a construction BIM. The construction BIM is updated by the process management system 6 and sent to the progress management system 7.

[0191] The input unit 72 accepts input of progress management information. The progress management information includes identification information for identifying panoramic photographs (360-degree images) taken within the building and indications. The input unit 72 accepts input of progress management information by receiving the progress management information from the user terminal 50.

[0192] Panoramic photographs (360-degree images) may be taken by, for example, a worker wearing an omnidirectional imaging device moving around the construction site, or by, for example, flying a small unmanned aerial vehicle (drone) equipped with an omnidirectional imaging device within the construction site.

[0193] The input unit 72 also receives input of construction completion information indicating a construction location where construction has been completed. The construction completion information is transmitted from the quality control system 8 when construction has been completed at a construction location.

[0194] The business processing unit 73 displays a progress management screen for supporting progress management work on the user terminal 50. The business processing unit 73 executes processing related to the progress management work in response to a request from the user terminal 50. When the business processing unit 73 executes processing related to the progress management work, it requests the model update unit 74 to update the construction BIM.

[0195] The progress management screen presents the progress status to the user based on the construction BIM and progress management information. For example, the progress management screen may display the progress of each object on the construction drawing in a different color. The progress management screen may also display an icon near an object for which an issue has been registered. Furthermore, the progress management screen may allow the user to register notes regarding the progress in response to a user operation.

[0196] Furthermore, the progress management screen may display a three-dimensional construction drawing showing the progress status and a panoramic photograph taken at the same location so that they can be compared. In this case, the progress management screen may be able to enlarge or reduce the three-dimensional construction drawing. Furthermore, the progress management screen may be able to move to any position on the three-dimensional construction drawing in response to a user operation. The progress management screen may automatically switch the display of the panoramic photograph when the display is switched (enlarged, reduced, moved, etc.) on the three-dimensional construction drawing in response to a user operation.

[0197] 45 to 47 are examples of progress management screens. A user operates the progress management screens as shown in Fig. 45 to 47 to perform progress management tasks.

[0198] Fig. 45 shows the progress management screen when displaying a panoramic photograph, Fig. 46 shows the progress management screen when registering the progress status on a working drawing, and Fig. 47 shows the progress management screen when displaying a working drawing and a panoramic photograph.

[0199] The model update unit 74 updates the construction BIM in response to a request from the business processing unit 73. The model update unit 74 updates the construction BIM by registering progress management information in the attribute information of each object included in the construction BIM. Furthermore, when the model update unit 74 receives construction completion information, it registers the construction completion information in the attribute information of each object included in the construction BIM.

[0200] The output unit 75 outputs findings, etc. based on the construction BIM updated by the model update unit 74.

[0201] <Functional Configuration of Quality Control System> Fig. 48 is a block diagram showing an example of the functional configuration of the quality control system 8 in this embodiment. As shown in Fig. 48, the quality control system 8 in this embodiment includes a model storage unit 81, an input unit 82, a business processing unit 83, a model update unit 84, and an output unit 85.

[0202] The model storage unit 81 is realized, for example, by the HDD 504 shown in Fig. 2. The input unit 82, the business processing unit 83, the model update unit 84, and the output unit 85 are realized, for example, by the CPU 501 executing a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503.

[0203] The model storage unit 81 stores a construction BIM. The construction BIM is updated by the progress management system 7 and sent to the quality management system 8.

[0204] The input unit 82 accepts input of quality control information. The quality control information includes construction photos taken at the construction site, blackboard information, inspection lists, etc. The input unit 82 may also accept input of panoramic photos and generate progress management information. The input unit 82 accepts input of quality control information by receiving the quality control information from the user terminal 50.

[0205] The construction photograph is, for example, an image of the construction site taken by a worker involved in the construction after the work has been completed. Alternatively, for example, the construction photograph may be a cut-out image of the construction site after the work has been completed that is captured in a panoramic photograph included in the progress management information.

[0206] It is also possible to share information other than photographic data. When sharing image data of the inside of walls or ceilings for progress management in operation management (maintenance), it is shared based on the position and direction linked to the BIM model. Similarly, quality control management information (inspection date and time) is also shared based on the position and direction linked to the BIM model.

[0207] The business processing unit 83 displays a quality control screen for supporting quality control work on the user terminal 50. The business processing unit 83 executes processing related to the quality control work in response to a request from the user terminal 50. After executing processing related to the quality control work, the business processing unit 83 requests the model update unit 84 to update the construction BIM.

[0208] The quality control screen presents the construction status to the user based on the construction BIM and quality control information. For example, the quality control screen may set inspection points on a construction drawing and display progress management information (e.g., findings) and quality control information (e.g., construction photos and blackboard information) associated with each inspection point. At this time, a panoramic photograph taken before construction at the inspection point may also be associated and displayed. That is, the quality control screen 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 in a manner that allows comparison with the panoramic photograph.

[0209] The quality control screen also outputs various reports in response to user operations. Examples of reports include trial operation reports, measurement reports, and as-built drawings. The quality control screen outputs reports in formats appropriate for each object included in the construction BIM. Because the construction BIM includes panoramic photographs and construction photos, it is possible to output, for example, a report that includes before- and after-construction photos for each inspection point.

[0210] Furthermore, the quality control screen may output memos describing important points or issues to be noted at the construction site. This information can be used to communicate with construction site workers who are unable to use the user terminal 50, or as educational materials for personnel with little experience at construction sites.

[0211] The quality control screen may output an inspection list in a format appropriate for each object included in the construction BIM. The inspection list is information that lists the points that should be inspected for the object, and construction site managers and others can use blank inspection lists to efficiently carry out inspections.

[0212] 49 to 51 are examples of quality control screens. A user operates the quality control screens as shown in Fig. 49 to 51 to perform quality control tasks.

[0213] Fig. 49 is a quality control screen when issuing a correction instruction, Fig. 50 is a quality control screen when displaying a correction instruction, and Fig. 51 is a quality control screen when displaying a construction photo ledger.

[0214] 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.

[0215] 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. In addition, the output unit 85 outputs reports and the like based on the construction BIM updated by the model update unit 84.

[0216] <Functional Configuration of the Operation Management System> Fig. 52 is a block diagram showing an example of the functional configuration of the operation management system 9 in this embodiment. As shown in Fig. 52, 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.

[0217] 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 a program loaded from the HDD 504 shown in Fig. 2 onto the RAM 503, which is executed by the CPU 501.

[0218] An operational BIM is stored in the model storage unit 91. 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.

[0219] 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.

[0220] 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.

[0221] The model update unit 94 updates the operational BIM in response to a request from the business processing unit 93. The model update unit 94 updates the operational BIM by registering operation management information in the attribute information of each object included in the operational BIM. Therefore, the operational BIM stores history data such as operation data, inspection data, and maintenance data related to buildings currently in operation.

[0222] 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.

[0223] <Functional Configuration of Information Sharing System> Fig. 53 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. 53, the information sharing system 10 according to this embodiment includes a shared information storage unit 101 and an information providing unit 102.

[0224] 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.

[0225] 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.

[0226] 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.

[0227] <Processing Procedure of Collaborative Work Support Method> The collaborative work support method executed by the collaborative work support system 100 in this embodiment will be described with reference to Fig. 54. Fig. 54 is a flowchart showing an example of the collaborative work support method in this embodiment.

[0228] 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, first, 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. Then, the estimate support system 2 sends the initial estimate BIM to the cost analysis system 4 and the working drawing creation system 5.

[0229] In step S2, the automatic design system 1 executes design work processing in response to a request from the user terminal 50. Specifically, first, 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. Then, the automatic design system 1 sends the design BIM to the cost analysis system 4 and the working drawing creation system 5.

[0230] In step S3, the inquiry system 3 executes inquiry processing in response to a request from the user terminal 50. Specifically, first, 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.

[0231] 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.

[0232] 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, first, 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.

[0233] 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.

[0234] 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, first, 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.

[0235] 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, first, the process management system 6 receives the construction BIM from the working drawing creation 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.

[0236] In step S8, the progress management system 7 executes the progress management work in response to a request from the user terminal 50. Specifically, first, the progress management system 7 receives the construction BIM from the process management system 6. Next, the progress management system 7 receives the 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.

[0237] In step S9, the quality control system 8 executes quality control work processing in response to a request from the user terminal 50. Specifically, first, 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.

[0238] 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.

[0239] 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.

[0240] In step S11, the operation management system 9 executes processing of operation management tasks in response to a request from the user terminal 50. Specifically, first, 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.

[0241] 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.

[0242] <Outline of Cooperation Between Business Systems> Cooperation between the process management system 6, the progress management system 7, and the quality management system 8 will be described with reference to FIGS. 55 to 60. FIG.

[0243] 55 is a diagram showing an example of cooperation between business support systems. As shown in FIG. 55, a process control system 6, a progress control system 7, and a quality control system 8 are configured to be able to cooperate with each other via a BIM model M.

[0244] FIG. 56 is a diagram illustrating an example of collaboration between a process management system and a progress management system. As shown in FIG. 56 , the progress management system 7 and the process management system 6 first reference each other's information. The referenced information includes, for example, information on the schedule, information on each process line, and information on the BIM model (project ID, version ID) from which the schedule was created. Based on the matching of the projects, the schedule information, information on each process line, and so on are shared with the progress management system 7, allowing the progress management system 7 to display the schedule in synchronization with the process management system 6. After synchronization, the progress management system 7 acquires a list of processes from the process management system 6 and shares the tasks. The user colors each task as a progress management task. The coloring is performed by inputting, for example, "not started," "in progress," "completed," and "approved" on an object-by-object basis. Based on this information, the progress rate for each task to which the object belongs is calculated. For example, as shown in FIG. 57 , for a task called "duct construction" in a certain construction section, if there are three objects that make up the duct construction, and the statuses of the three objects are "not started," "approved," and "not started," the progress rate is 33%. Among the multiple tasks managed by the process control system 6, there are tasks that are linked with the progress control system 7 (for example, tasks related to objects, such as installation, construction, and processing) and tasks that are not linked (for example, tasks not related to objects, such as inspection, management, and check). The progress control system 7 can also make a request to the process control system 6 and receive the progress status of the tasks. According to this information, the objects belonging to the corresponding tasks can be colored.

[0245] FIG. 57 is a diagram showing an example of data shared between the process management system and the progress management system. As shown in FIG. 57, the data shared between the process management system and the progress management system includes the process name, process type, floor, external ID, progress, etc. Note that information sharing is not performed when the project IDs are different, but information sharing is possible when the version IDs are different. That is, in cases where the progress management system 7 manages the progress of a BIM model updated from the BIM model used when the process schedule was created in the process management system 6, or vice versa, the external IDs included in the version of the process management system 6 and the external IDs included in the version of the progress management system 7 can be compared to identify newly added objects and to identify moved or changed objects based on the change history of their position and shape. In this case, a notification is issued to indicate the existence of newly added or deleted objects, or moved or changed objects. This allows the user to recognize the discrepancy. A notification may also be issued when the version IDs differ.

[0246] FIG. 58 is a diagram illustrating an example of collaboration between a process control system and a quality control system. As shown in FIG. 58, the process control system 6 and the quality control system 8 first reference each other's information. The referenced information includes, for example, information on the process schedule, information on each process line, and information on the BIM model (project ID, version ID) from which the process schedule was created. This information is used to determine whether the projects match. Inspection documents are linked to the inspection process line. Inspection documents are used to check the completion of a process, and obtaining the check status from the quality control system can reflect whether the process has been completed. Inspection documents include those set for each work area and those used for equipment performance inspections and airflow inspections of air outlets. Inspection documents set for a work area can be obtained by requesting inspection documents for a specific work area from the process control system 6. Inspection documents linked to objects such as equipment and air outlets are requested based on external IDs. Note that information collaboration is not performed when the project IDs are different, but information collaboration is possible when the version IDs are different. That is, in cases where the quality control system 8 performs quality control on a BIM model updated from the BIM model used when creating a schedule in the process control system 6, or vice versa, the external ID included in the version of the process control system 6 can be compared with the external ID included in the version of the quality control system 8 to identify newly added objects and to identify moved or changed objects based on the change history of their position and shape. In this case, a notification is issued that there is a newly added or deleted object, or an object that has been moved or changed. This allows the user to recognize the discrepancy. A notification may also be issued when the version IDs are different.

[0247] 59 is a diagram showing an example of data shared between the process control system and the quality control system. As shown in Fig. 59, the data shared between the process control system and the quality control system includes area, type of work, construction, external ID, type, quality control, etc.

[0248] Figure 60 is a flowchart showing an example of the flow of collaboration between business support systems. As shown in Figure 60, the process management system 6 imports a construction BIM, creates a process chart, and performs process progress input operations. The progress management system 7 imports a construction BIM, creates a 3D image for progress management, and colors the progress status. Furthermore, the quality management system 8 imports a construction BIM, creates 3D and 2D images for quality control, and performs quality control processing.

[0249] The progress management system 7 then receives data from the progress management system 6 and performs coloring based on the progress management system 6. The progress management system 6 receives data from the progress management system 7 and displays the progress rate based on the progress management system 7. The process management system 6 receives data from the quality management system 8 and creates inspection documents based on the quality management system 8. The progress management system 7 and the quality management system 8 can be linked. First, the progress management system 7 and the quality management system 8 reference each other's information. The referenced information includes, for example, information on the schedule, information on each process line, and BIM model information (project ID, version ID) from which the schedule was created. This determines whether the projects match. First, the quality management system 8 requests an image from the progress management system 7. The quality management system 8 specifies the location from which the image is desired. This location can be specified using absolute coordinates on the BIM model. The progress management system 7 uploads the image closest to the requested absolute coordinates to the server. Instead of specifying coordinates, the request can also be based on an external ID. In this case, the quality control system 8 can request the external ID of the object to be confirmed by specifying the object, and the progress management system 7 can upload an image containing the specified object. Note that information linkage is not performed if the project IDs are different, but information linkage is possible if the version IDs are different. That is, in cases where the quality control system 8 performs quality control on a BIM model updated from the BIM model that is the source of the progress management system 7, or vice versa, the external IDs included in the version of the progress management system 7 can be compared with the external IDs included in the version of the quality control system 8 to identify newly added objects and to identify moved or changed objects based on the change history of their position and shape. In this case, a notification is issued to indicate the existence of newly added or deleted objects, or moved or changed objects. This allows the user to recognize the discrepancy. A notification may also be issued when the version IDs differ.

[0250] <Effects of the embodiment> The collaborative work support system 100 in this embodiment includes a plurality of work support systems that support predetermined work related to construction. A first of the plurality of work support systems outputs a BIM model or information generated based on the BIM model. A second of the plurality of work support systems inputs a BIM model or information generated based on the BIM model. In other words, the first and second work support systems collaborate to input and output the BIM model or information generated based on the BIM model. Therefore, the collaborative work support system 100 in this embodiment can further improve the efficiency of work performed in the life cycle of a building.

[0251] The collaborative work support system 100 in this embodiment stores shared information shared among multiple work support systems, and each work support system acquires the shared information. The shared information is stored in an external storage device (e.g., information sharing system 10) that is different from the multiple work support systems, and each work support system acquires the shared information by connecting to the storage device via a network. Therefore, the collaborative work support system 100 in this embodiment allows each task to be executed accurately based on common information throughout the life cycle of a building.

[0252] The estimate support system 2 in this embodiment creates a BIM model without height information based on two-dimensional data. The estimate support system 2 executes the task of calculating the construction costs of a building based on the BIM model without height information. In other words, the estimate support system 2 can estimate construction costs with simple calculations without considering the height direction in situations where a precise estimate is not required. Therefore, the collaborative work support system 100 in this embodiment allows efficient estimate work based on the BIM model. In addition, converted members and parts are displayed in 3D, while unconverted members and parts are displayed as line drawings, which can be rotated and displayed in a perspective view within a single drawing, allowing workers to intuitively determine omissions.

[0253] The estimate support system 2 in this embodiment calculates construction costs by multiplying the cost estimation information based on a BIM model that does not have information about height by a coefficient corresponding to the height. In other words, the business support system can calculate construction costs according to the height even when estimating construction costs based on a BIM model that does not have information about height and without considering the height direction. Therefore, the collaborative business support system 100 in this embodiment can efficiently estimate construction costs with high accuracy based on a BIM model.

[0254] The working drawing creation system 5 in this embodiment creates a BIM model with information about height based on a BIM model without information about height. That is, the working drawing creation system 5 executes the task of creating working drawings from the BIM model generated by the estimate support system 2. Because working drawings are created based on the same BIM model used to create the cost estimation information, the risk of discrepancies occurring between the cost estimation information and the working drawings is reduced. Therefore, the collaborative work support system 100 in this embodiment can efficiently create highly accurate working drawings based on the BIM model.

[0255] The process management system 6 in this embodiment acquires a BIM model showing the construction drawings of a building, and displays a process management screen 600 for managing a process schedule created based on the BIM model. By utilizing the BIM model created in the previous process, it is not necessary to write a process schedule from scratch, and the process schedule can be created in a short period of time. In one aspect, this embodiment improves the efficiency of process management work.

[0256] The process management system 6 may reflect progress information input in the progress management system in the process management. The process management system 6 may reflect completion information input in the quality management system in the process management. According to this embodiment, the progress status managed by another business support system can be easily reflected in the process schedule.

[0257] The process control system 6 may create a process schedule for each work section based on the working drawings for each of the multiple work sections. According to this embodiment, a process schedule for each work section can be created collectively, and the process schedule can be created accurately taking into account the relationship between the work sections.

[0258] The process management screen 600 may set a chronological relationship in the process schedule according to an operation for setting a chronological relationship between multiple tasks shown in the process schedule. The operation for setting a chronological relationship may be an operation of dragging from the end of a preceding task to the beginning of a succeeding task. According to this embodiment, the chronological relationship between tasks can be set with a simple operation.

[0259] The process control system 6 may correct the length of each task shown in the process schedule based on a coefficient specified by the user. The coefficient may be determined for each attribute of the task type or the location where the task is performed. According to this embodiment, the attribute of the task type or location can be reflected in the task length, allowing for accurate creation of a process schedule.

[0260] The process management screen 600 may display non-working days in accordance with a vacation pattern designated by the user on the schedule. According to this embodiment, a schedule that reflects different vacation patterns for each site can be created.

[0261] The process management screen 600 may display milestones designated by the user on the process schedule. According to this embodiment, the user can easily determine the validity of the process schedule.

[0262] The process management screen 600 may display the progress status of each task on a schedule. The process management screen may also display progress lines on the schedule, indicating the relationship between the progress statuses of tasks. According to this embodiment, the user can easily visually check the progress status of each task, and can efficiently manage budgets and actuals.
