[0008] 1. Example Examples of this embodiment will be described below with reference to the drawings. 1-1. Overview First, an outline of this embodiment will be described. When a contract for construction work is made, the general contractor, who is the prime contractor, usually presents design information such as blueprints to the subcontractor. Then, the general contractor and the subcontractor exchange construction estimates and conclude a construction contract.

[0009] However, when a construction contract is signed, the information on construction design provided by the general contractor to the subcontractor is often significantly different from the construction drawings at the time of completion, and the information is often insufficient for the subcontractor to carry out the construction. As a result, construction contracts are signed without the actual construction costs being clear to both the general contractor and the subcontractor. Therefore, when calculating the construction cost, they are forced to submit estimates that place more emphasis on safety, which can result in an estimate that is significantly different from the estimate based on the actual construction costs.

[0010] Furthermore, if there is a large difference in the amount of information between the design information at the time of the contract and the construction information during or after the construction is completed, the general contractor and subcontractor may have to settle the difference. Therefore, when distributing the construction profits among the construction participants, it becomes difficult to calculate an appropriate distribution ratio.

[0011] On the other hand, it is possible for the subcontractor to use the BIM model created by the general contractor at the contract stage or after the contract has been signed to reduce construction costs after construction has begun. However, even if the construction profit increases, if the increased construction profit goes to the subcontractor, there will be no incentive for the general contractor to create and use BIM.

[0012] Therefore, in this embodiment, a contract is concluded to distribute the construction profits among the companies participating in the construction, such as an IPD (Integrated Project Delivery) contract, and furthermore, by using the BIM model at the contract stage or after the contract is signed, it is possible to grasp information such as the construction content and the required quantities of building materials before the construction begins.

[0013] Specifically, in this embodiment, the following can be implemented. (1) A profit-sharing agreement will be concluded between the companies participating in the construction project. (2) The share of the construction profits between the contracted construction participants (for example, the general contractor and the subcontractor) is determined. The share of the construction profits is updated by mutual approval between the construction participants. (3) Obtain construction quantity information (contract quantity information) at the time of the construction contract. The contract quantity information may be obtained based on the BIM data at the time of the construction contract. (4) Contract quantity information and unit price information are approved among the companies participating in the construction work. (5) Acquire quantity information (implemented quantity information) during or after the construction work is completed. The implemented quantity information may be acquired based on BIM data after the construction work (construction) has started or has been completed. (6) When construction work is carried out using a new construction method such as pre-cutting that improves the rate of work compared to normal construction methods, the registered contents of the changed quantity (such as information on the rate of work by type) are changed. (7) The general contractor and subcontractor approve the implementation quantity information and unit price information. (8) The profit amount is calculated by multiplying the difference in quantity between the contract quantity information and the implementation quantity information by the unit price information, and the distribution profit amount for each construction participating company is determined by multiplying this profit amount by the distribution rate.

[0014] Furthermore, this embodiment makes it possible to use the BIM model to trace changes to architectural design and construction specifications after construction work has begun, making it possible to clearly state the content and basis of changes in quantities, work rates, etc.

[0015] For example, by using BIM data, subcontractors can carry out construction work at lower costs than expected at the time of the contract, which increases their profits. Also, general contractors can increase the level of detail in BIM data as construction progresses, allowing them to obtain accurate quantity information at the time of completion.

[0016] Furthermore, with this embodiment, when a general contractor and a subcontractor enter into a contract to share the construction profits, the general contractor can be more motivated to create and manage BIM data, and the subcontractor can be more motivated to reduce construction costs during construction based on the BIM data created by the general contractor.

[0017] 1-2.Configuration FIG. 1 shows an example of the configuration of a profit share output system 10. The profit share output system 10 shown in the figure includes a management server 102, a general contractor terminal 103, and a construction company terminal 104, which are interconnected via a network 101 so as to be able to communicate with each other.

[0018] Of these components, the management server 102 is a server device that manages the construction costs of the target construction project. The management server 102 outputs the distribution amount of the construction profit amount (hereinafter referred to as "profit amount") on the construction costs to the construction participating companies. In a construction project, for example, a general contractor and a subcontractor are registered as construction participants. The general contractor terminal 103 is a terminal device installed in the general contractor, and is used by users of the general contractor. The construction shop terminal 104 is a terminal device installed in a construction shop and is used by users of the construction shop.

[0019] The following description will be given of a case where two companies, a general contractor and a contractor, are participating in a construction project, but three or more companies may participate. Also, for example, multiple general contractor terminals 103 and multiple contractor terminals 104 may be connected.

[0020] Each device constituting the gain share output system 10 may be, for example, a portable terminal (mobile terminal) such as a smartphone, tablet, mobile phone, or personal digital assistant (PDA), or a wearable terminal such as glasses, a wristwatch, or clothing. It may also be a stationary or portable computer, or a server located on the cloud or a network. In terms of functionality, it may be a VR (Virtual Reality) terminal, an AR (Augmented Reality) terminal, or an MR (Mixed Reality) terminal. Alternatively, it may be a combination of multiple of these terminals. For example, a combination of one smartphone and one wearable terminal may logically function as one terminal. Other information processing terminals may also be used.

[0021] Each device constituting the profit share output system 10 includes a processor that executes an operating system, applications, programs, etc., a main storage device such as a RAM (Random Access Memory), an auxiliary storage device such as an IC card, a hard disk drive, an SSD (Solid State Drive), or a flash memory, a communication control unit such as a network card, a wireless communication module, or a mobile communication module, an input device such as a touch panel, a keyboard, a mouse, voice input, or input based on motion detection captured by a camera unit, and an output device such as a monitor or a display. The output device may also be a device or terminal that transmits information to be output to an external monitor, display, printer, or device.

[0022] The main memory stores various programs, applications, etc. (modules), and the processor executes these programs and applications to realize the various functional elements of the overall system. These modules may be implemented in hardware, such as by integration. Each module may be an independent program or application, or may be implemented as a subprogram or function within a single integrated program or application.

[0023] In this specification, each module is described as the entity (subject) that performs the processing, but in reality, the processing is carried out by a processor that processes various programs, applications, etc. (modules). Various databases (DBs) are stored in the auxiliary storage device. A "database" is a functional element (storage unit) that stores a set of data so that it can accommodate any data manipulation (e.g., extraction, addition, deletion, overwriting, etc.) from a processor or an external computer. There are no limitations on how the database is implemented; for example, it can be a database management system, spreadsheet software, or a text file such as XML or JSON. Each component will be described in detail below.

[0024] 1-2-1. Management Server 102 FIG. 2 shows an example of the configuration of the management server 102. The management server 102 is configured, for example, by a server placed on a cloud.

[0025] The management server 102 includes a main storage device 201 , an auxiliary storage device 202 , a processor 203 , an input device 204 , an output device 205 , and a transmission / reception unit 206 .

[0026] Of these, the main memory device 201 stores programs and applications such as a distribution rate acquisition module 211, a contract amount information acquisition module 212, an executed amount information acquisition module 213, a profit amount calculation module 214, a distribution amount output module 215, and a construction cost management module 216, and the processor 203 executes these programs and applications to realize various functional elements of the management server 102. The application is, for example, a construction cost management application (hereinafter sometimes referred to as an "app").

[0027] The distribution ratio acquisition module 211, contract amount information acquisition module 212, execution amount information acquisition module 213, profit amount calculation module 214, distribution amount output module 215, etc. are realized, for example, by the processor 203 executing the construction cost management module 216 (construction cost management application).

[0028] For example, the distribution ratio acquisition module 211, the contract amount information acquisition module 212, and the execution amount information acquisition module 213 work in cooperation with each module of the general contractor terminal 103 and the construction company terminal 104 to acquire information such as the distribution ratio, contract amount information, and execution amount information sent from the general contractor terminal 103 and the construction company terminal 104, and store this information in the distribution ratio registration information 225 of the auxiliary memory device 202. Each module will be explained below.

[0029] The distribution rate acquisition module 211 acquires the distribution rate of the construction profit amount of the construction work. In addition, the distribution rate acquisition module 211 stores the subject (for example, a company) who approved the contract content of the construction work as a subject participating in the construction work. For example, the distribution rate acquisition module 211 cooperates with the general contractor terminal 103 and the construction company terminal 104 to acquire information transmitted from the general contractor terminal 103 and the construction company terminal 104 and registers the information in the auxiliary storage device 202 . The distribution rate acquisition module 211 is realized, for example, by the processor 203 executing a construction cost management application.

[0030] The contract amount information acquisition module 212 acquires contract amount information related to the construction price before the start of construction work. The contract amount information acquisition module 212 may also calculate the contract amount information based on construction work BIM (Building Information Modeling) data before the start of construction work. The contract price information is information used to determine the contract price, which is the construction price at the time of the contract for the construction work. Note that the contract price may also be the construction price before the contract is concluded. Specifically, the construction price at the time of the contract is quantity information at the time of the contract (referred to as "contract quantity information"), which includes information such as the price, size, and weight of building materials corresponding to each type of work at the time of the contract, and quantified information on units and labor, as well as unit price information for building materials, units, labor, etc. at the time of the contract. The contract price and contract quantity price are, for example, prices that are determined by approval between the construction work participating companies when a construction contract is made between the construction work participating companies.

[0031] The construction cost information acquisition module 213 acquires construction cost information related to the construction price that will be determined after construction work has started. The construction cost information acquisition module 213 may also calculate and acquire construction cost information based on BIM data of the construction work after construction has started. The construction cost information is quantity information used to determine the construction price after the start or completion of construction work. Specifically, the quantity information is quantified information such as the price, size, and weight of building materials corresponding to each type of work, as well as the rate of work and labor, etc., after the start or completion of construction work. In addition, the execution amount information is calculated based on quantity information after the start of construction work (referred to as "execution quantity information"), and unit price information for building materials, labor, etc., and is determined, for example, by approval between the companies participating in the construction work after the start or completion of construction work.

[0032] The execution cost information acquisition module 213 is realized, for example, by the processor 203 executing a construction cost management application. For example, the distribution rate acquisition module 211 cooperates with each module of the general contractor terminal 103 and the construction company terminal 104 to acquire execution cost information transmitted from the general contractor terminal 103 and the construction company terminal 104, and registers this in the auxiliary storage device 202.

[0033] The execution amount information acquisition module 213 receives changed quantity information indicating a change in the corresponding execution quantity information when construction work is carried out using a new construction method that improves the unit rate compared to the normal construction method in a construction project. Examples of cases where construction work is carried out using a new construction method include using pre-cut building materials, changing to building materials or construction methods that improve the production rate, or reducing the required quantity of building materials. For example, the execution cost information acquisition module 213 accepts changes to the information stored in the execution cost information 224. More specifically, it accepts changes to the values ​​written in the execution cost quantity column, unit price column, amount column, composite unit price column, etc. of the execution cost information 224. The execution cost information 224 will be described later.

[0034] When the spent amount information acquisition module 213 receives the changed quantity information, it changes the registered content information and updates the spent amount information based on the changed quantity information. When updating the execution amount information, for example, if the change in quantity information that increases the construction work rate is received, the profit amount will be increased. Also, if the change in quantity information that decreases the work rate is received, the profit amount may be decreased.

[0035] The profit calculation module 214 calculates the construction profit based on the difference between the total contract amount calculated based on the contract amount information and the total implementation amount calculated based on the implementation amount information, for example. The profit calculation module 214 calculates the total contract amount by adding up the contract amount information, and calculates the total implementation amount by adding up the implementation amount information. The profit calculation module 214 calculates the construction profit based on the difference between the total contract amount and the total implementation amount. For example, the profit calculation module 214 calculates the construction profit by subtracting the lower of the total contract amount and the total execution amount from the higher amount. The profit amount calculation module 214 may calculate the total contract amount and the total execution amount based on the BIM data of the construction work.

[0036] Furthermore, the profit calculation module 214 may calculate the construction profit by multiplying the difference between the contract quantity information and the execution quantity information by unit price information for building materials, work, labor, etc., for example.

[0037] The distribution amount output module 215 outputs the distribution amount to the construction project participants (construction participating companies) based on the construction profit amount and the distribution rate. For example, the distribution amount output module 215 calculates and outputs the distribution amount by multiplying the construction profit amount by the distribution rate.

[0038] The construction cost management module 216 controls each of the above modules. The construction cost management module 216 (construction cost management application) may execute the processing of each of the above modules, or the construction cost management module 216 (construction cost management application) may implement processing in cooperation with each module, which is each of its sub-modules (applications, etc.).

[0039] The construction cost management module 216 cooperates with the general contractor terminal management module 311 and the construction company terminal management module 411, and outputs various screen information shown in FIGS. 12 to 19 to each terminal.

[0040] Next, the auxiliary storage device 202 will be described. The auxiliary storage device 202 stores contract quantity information 221, implementation quantity information 222, contract unit information 223, implementation unit information 224, distribution rate registration information 225, calculation standard information 226, contract total amount information 500, implementation total amount information 600, etc. Each piece of information will be explained below.

[0041] Figure 14 shows an example of contract quantity information 221 displayed on the contract quantity display screen 1400. The information shown in the figure is made up of records by work type, including an identification ID, construction type, detail name, detail name 2, detail name 3, specification 1, specification 2, specification 3, unit, quantity at time of contract, unit price at time of contract (yen), amount (yen), etc. The contract quantity information 221 stores quantity information related to the construction work at the time of the contract before the construction work is carried out.

[0042] The information that makes up each record indicates attribute information for each type of work, which is distinguished by an identification ID. For example, a record with identification ID "A00021" and work type "metal work" indicates the type of work (e.g., metal work), the detail name is the name of the work, "lightweight steel frame base," detail names 2 and 3 are another name for the work, "lightweight steel frame for eaves ceiling," and specifications 1, 2, and 3 indicate information on the specifications of the work, respectively. In addition, "unit" indicates the unit of work for each record, the quantity at contract indicates the quantity used in the work for each record, the unit price at contract (yen) indicates the unit price of the work, and the amount (yen) indicates the amount calculated by multiplying the unit price at contract (yen) by the quantity at contract.

[0043] For example, the construction record identification ID "A00021" at the top of the contract quantity information 221 indicates that the item name is "lightweight steel frame substructure," the quantity to be used in the construction work subject to the contract is 70, the unit price at the time of contract is 4,200 yen, and the total amount is 294,000 yen (unit price 4,200 yen x quantity 70).

[0044] 15 shows an example of contract unit information 223 displayed on a contract unit display screen 1500. The information shown in the figure is made up of records consisting of an identification ID, construction type, item name, item name 2, item name 3, specification 1, specification 2, specification 3, unit, expense item, product name, unit, unit quantity, unit price, amount, composite unit price, etc. Furthermore, in the contract unit information 223, each record contains multiple different sub-records.

[0045] For example, the top record of the contract unit price information 223 includes product name sub-records for studs, runners, spacers, drive pins, steady rests, interior work, and others, with each sub-record corresponding to an expense item, unit, unit price, unit price, and amount. The expense item indicates the type of sub-record (e.g., "materials" or "labor"). The unit, unit price, unit price, and amount values ​​correspond to each sub-record. For example, the unit for the sub-record "studs" is "m," the unit price is "3.5," the unit price is "500 yen," and the amount is "1750 yen" (calculated by multiplying the unit price by the unit price). Furthermore, the value of the record "composite unit price" is the sum (4070) of the amount record values, i.e., 1750, 360, 153, 20, 126, 980, and 678.

[0046] The above units, unit quantities, composite unit prices, etc. are calculated based on the Building Quantity Estimation Standards, which are estimation standards that define the measurement and calculation methods for calculating the quantities of each type of work, and the Standard Format for Construction Work Breakdown, which defines the standard format for breakdowns that show the basis for calculating estimated prices. These estimation standards are stored in the estimation standard information 226.

[0047] Figure 16 shows an example of the implementation quantity information 222 displayed on the implementation quantity display screen 1600. The information shown in the figure is made up of records by work type, including an identification ID, construction type, detail name, detail name 2, detail name 3, specification 1, specification 2, specification 3, unit, quantity at time of contract, unit price at time of contract (yen), amount (yen), etc. The implementation quantity information 222 stores quantity information related to construction work that is acquired after construction work has started or has been completed.

[0048] The information constituting each record is similar to the contract quantity information 221 in Figure 14, and indicates attribute information for construction work by type of work, distinguished by identification ID. For example, a record with identification ID "A00021" and construction type "metal work" indicates the type of construction (e.g., metal work), the detail name is the name of the construction work "lightweight steel frame substructure," detail names 2 and 3 indicate another name for the construction work "eave ceiling lightweight steel substructure," and specifications 1, 2, and 3 indicate information on the specifications of the construction work, respectively. Furthermore, "unit" indicates the unit of construction for each record, the quantity at contract indicates the quantity used in the construction work for each record, the unit price at contract (yen) indicates the unit price of the construction work, and the amount (yen) indicates the amount calculated by multiplying the value of the unit price at contract (yen) by the value of the quantity at contract.

[0049] In the implementation quantity information 222, for example, for the top row identification ID "A00021," the value of the quantity to be used during construction (cell 1651) has decreased to 65, and the value of the amount in cell 1652 has decreased to 273,000 yen; for identification ID "A00023," the value of the quantity to be used during construction (cell 1653) has decreased to 110, and the value of the amount in cell 1654 has decreased to 539,000 yen; each of these has changed from the quantity at the time of the contract (contract quantity in Figure 14), and is highlighted in a color (for example, red) indicating an improvement in the unit rate. On the other hand, the value of the quantity of metalwork performed (cell 1655) for identification ID "A00025" has increased to 100, and the amount in cell 1656 has increased to 460,000 yen, and these are highlighted in a color (e.g., green) indicating that the unit rate has decreased compared to when the contract was signed.

[0050] As described above, in the implemented quantity information 222, cells of quantity information that have been changed from the contracted quantity information 221 are displayed in an emphasized manner.

[0051] Next, an example of the actual unit information 224 displayed on the actual unit display screen 1700 in Fig. 17 is shown. Similar to the contract unit information 223, the information shown in the figure is made up of records each consisting of the type of work, item name, item name 2, item name 3, specification 1, specification 2, specification 3, unit, expense item, product name, unit, unit quantity, unit price, amount, composite unit price, etc. Furthermore, similar to the contract unit information 223, each record in the actual unit information 224 contains multiple different sub-records.

[0052] For example, the top-level metalwork record in the work rate information 224 includes sub-records for product names such as studs, runners, spacers, drive pins, steady rests, interior work, and others, with each sub-record corresponding to an expense item, unit, unit quantity, unit price, and amount. The expense item indicates the type of sub-record (e.g., "materials" or "labor"). The unit, unit quantity, unit price, and amount values ​​correspond to each sub-record. For example, the unit for the sub-record "interior work" is "person (or labor)," the expense item is labor, the unit quantity (cell 2241) is "0.014," the unit price is "35,000 yen," and the amount in cell 2242 is "490 yen" (calculated by multiplying the unit price by the unit quantity). As a result, the value of the composite unit price in cell 2246 has changed to "3,480 yen." In other words, the unit price in cell 2142, "0.014," has been reduced by half from the contracted unit price of "0.028," and as a result, the amount and composite unit price have decreased.

[0053] The above units, unit quantities, composite unit prices, etc. are calculated based on the Construction Quantity Estimation Standards, which are estimation standards that stipulate the measurement and calculation methods for calculating the quantities of each type of work, and the Standard Format for Construction Details, which stipulates the standard format for breakdowns that show the basis for calculating estimated prices.

[0054] The distribution rate registration information 225 includes the distribution rate of the construction profit amount acquired by the distribution rate acquisition module 211. The distribution rate is, for example, information input by the distribution rate acquisition module 211 in an app that links with each module of the general contractor terminal 103 and the construction company terminal 104. The distribution rate is transmitted from the general contractor terminal 103 and the construction company terminal 104, and is stored in the distribution rate registration information 225 by the distribution rate acquisition module 211.

[0055] Next, the contract total amount information 500 will be described. FIG. 5 is an example of the contract total amount information 500.

[0056] The contract total amount information 500 includes, for example, data on construction costs (estimated amounts) estimated at the stage when participating companies in a construction project enter into a contract related to their participation in the construction, such as an IPD contract. The contract total amount information 500 is made up of records including the construction ID, construction name, construction period, material amount at the time of contract, labor amount at the time of contract, other amounts at the time of contract, and contract total amount.

[0057] The construction ID is a unique ID for each construction project. The construction name is the name of each construction project. It may also be the name or address of the building where each construction project is being carried out. The construction period indicates the date, time, and period when the construction project will be carried out or is scheduled to be carried out. The contract material amount is the total amount of construction material costs at the time of the construction contract. The contract labor amount is the total amount related to construction labor estimated at the time of the construction contract. Other amounts at the time of the contract are amounts included in the contract construction amount other than building material costs and labor. The contract total amount is the total estimated amount of construction costs at the contract stage.

[0058] The numerical data of the contract total amount information 500 may be information automatically acquired from BIM data at the time of the contract (contract BIM data). The contract BIM data is, for example, data including a BIM model created by a general contractor of a construction company participating in the construction.

[0059] Next, the transaction total amount information 600 will be described. FIG. 6 is an example of the transaction total amount information 600.

[0060] The total construction cost information 600 is, for example, construction costs calculated based on quantity information that is confirmed after construction work has started or completed. The total cost information 600 is made up of records including the construction ID, construction name, construction period, material cost after construction, labor cost after construction, other cost after construction, and total cost after construction.

[0061] The construction ID, construction name, and construction period are the same as those in the contract total amount information 500 in Figure 5. The post-completion material amount is the total value of the building material costs that is determined each time after construction begins or is completed. The contract labor amount is the total value of the amounts related to construction labor that is determined each time after construction begins or is completed. "Other post-completion amounts" are amounts included in the total construction amount excluding building material costs and labor.

[0062] The numerical data of the total construction cost information 600 may be information automatically acquired from BIM data after the start of construction (construction BIM data). The construction BIM data is, for example, data including a BIM model created by a general contractor of a construction company during or after the construction.

[0065] The general contractor terminal management module 311 displays various screens on the display and accepts operations from the general contractor terminal user. The general contractor terminal management module 311 also stores the data and estimation information input by the general contractor terminal user in the auxiliary storage device 302 as general contractor-side estimation information 321. The contract-related information management module 312 stores information related to the construction contract in the contract-related information 322 of the auxiliary storage device 302 in response to an operation by the general contractor terminal user.

[0066] 1-2-3.Construction shop terminal 104 Next, the configuration of the contractor terminal 104 will be described. FIG. 4 shows an example of the configuration of the construction shop terminal 104. The construction shop terminal 104 is, for example, a stationary or portable computer device used by an employee user of a construction shop that is a subcontractor.

[0067] The contractor terminal 104 includes a main memory device 401 , an auxiliary memory device 402 , a processor 403 , an input device 404 , an output device 405 , a camera 406 , and a communication control unit 407 . Of these, the main memory device 401 stores programs and applications such as a construction shop terminal management module 411 and a construction shop quantity management module 412, and the various functions of the construction shop terminal 104 are realized by the processor 403 executing these programs and applications.

[0068] The contractor terminal management module 411 cooperates with the application of the management server 102 to display various screens on the display and accept operations by the contractor user. The contractor quantity management module 412 registers and manages information on building materials managed by the contractor, as well as unit prices, commissions, and labor-related quantity information for each type of work.

[0069] Next, the configuration of the auxiliary storage device 402 will be described. The auxiliary storage device 402 stores contractor management information 421. The contractor management information 421 includes information on building materials managed by the contractor, unit prices for each type of work, commissions, and quantity information for each type of work related to labor. The auxiliary storage device 402 stores contractor cost estimate information 422. The contractor cost estimate information 422 is data and cost estimate information input by a terminal user of the contractor.

[0070] 1-3.Operation 1-3-1. Distribution amount output flow Next, the distribution amount output flow executed by the management server 102 will be described. FIG. 7 is an example of a distribution amount output flow 700. In the distribution amount output flow 700, the management server 102 calculates and outputs the distribution amount based on the acquired distribution rate and construction profit amount.

[0071] First, the distribution rate acquisition module 211 acquires information about the construction companies participating in the construction work and the distribution rate of the construction profit amount for each construction company (S710). For example, the distribution rate acquisition module 211 acquires the initial value of the distribution rate input from the general contractor terminal 103. The distribution rate acquisition flow will be described later (FIG. 8).

[0072] Next, the contract amount information acquisition module 212 acquires the contract amount information from the general contractor terminal 103 (S720). For example, the contract amount information is construction quantity information at the time of the construction contract.

[0073] Next, the construction cost information acquisition module 213 acquires construction cost information from the general contractor terminal 103 and the construction company terminal 104 (S730). The construction cost information is, for example, quantity information at the time of construction or after construction is completed, and the construction cost information acquisition module 213 acquires it from the general contractor terminal 103 or the construction company terminal 104, or from the general contractor terminal 103 and the construction company terminal 104, after construction work has started.

[0074] Next, the profit calculation module 214 calculates the construction profit based on the difference between the acquired contract amount information (contract quantity information) and the implementation amount information (implementation quantity information), and the distribution amount output module 215 calculates and outputs the distribution amount based on the construction profit amount and the distribution ratio (S740). For example, the contract quantity information is quantity information by type of work at the time of contract, and the implementation quantity information is quantity information by type of work after the start or completion of the work. The contract quantity information may be the total contract amount, and the implementation quantity information may be the total implementation amount.

[0075] For example, the distribution amount output module 215 calculates the distribution amount by multiplying the difference between the contract quantity information and the implementation quantity information by the distribution rate.

[0076] 1-3-2. Distribution ratio acquisition flow 800 Next, the distribution ratio acquisition flow (S710) executed by the management server 102 will be described. FIG. 8 shows an example of a distribution ratio acquisition flow 800. In a distribution rate acquisition flow 800 shown in the figure, the distribution rate acquisition module 211 of the management server 102 acquires the distribution rate determined based on information sent from the general contractor terminal 103 and the construction company terminal 104 .

[0077] First, the distribution rate acquisition module 211 acquires contract content information from the general contractor terminal 103 and the construction company terminal 104, and registers it in the auxiliary storage device 202 (S810). The contract content information includes, for example, the construction contract content of the construction project, the contract amount, information on the contracting party (prime contractor, subcontractor, construction company, etc.), the contents of the contract that has already been concluded, etc. More specifically, the contract content information includes the project ID of the construction project, the property name, the company attributes in this project (prime contractor, subcontractor), information such as the account name, documents such as the design documents that served as the basis for the contract, the contract, etc.

[0078] For example, the general contractor terminal management module 311 transmits contract content information input by a user of the general contractor terminal 103 on a contract input screen to the management server 102 .

[0079] FIG. 12 shows an example of a contract entry screen 1200. The contract entry screen 1200 includes a project information area 1210 , a contract operation button area 1220 , and a project content display area 1230 . Of these display elements, the project information area 1210 includes a search by project name button 1211, an all progress button 1212, an update order button 1213, an add new project button 1214, a project name display area 1215, and an update button 1219. Furthermore, the bottom area of ​​the project information area 1210 displays the contract details of the construction project. The contract details include, for example, a contract amount 1216, the name of the subcontractor 1217, and a construction profit amount 1218. For example, the project name display area 1215 displays the attribute information of the construction project, such as the project ID, property address, property name, and project name.

[0080] The Search by Project Name button 1211 is a button for searching for construction projects managed by the app. The All Progress button 1212 is a button for displaying a list of the progress of construction projects. The Update Order button 1213 is a button for sorting the listed construction projects in order of update. Furthermore, the Add New Project button 1214 is a button for transitioning to a registration screen for a new construction project.

[0081] For example, when the terminal user presses the update button 1219, the construction cost management module 216 updates the documents displayed in the project content display area 1230 to the latest documents. The registration button 1221 of the concluded contract in the contract operation button area 1220 is a button for starting the operation of registering an already concluded contract in this system, for example.

[0082] Operation buttons for importing new document data and the contents of the contract documents are displayed in the project content display area 1230. The operation buttons include a PDF import button 1231, a delete button 1232 for deleting imported document data, an approval button 1233 for approving the displayed documents, a contract amount registration / edit button 1234, and a contracting company registration / edit button 1235. For example, when the contract amount registration / edit button 1234 is pressed by the terminal user, the construction cost management module 216 displays a window for accepting operations such as registration processing of the displayed document 1236, editing of the registered content, etc. Also, for example, when the contract company registration / edit button 1235 is pressed, the construction cost management module 216 may superimpose an editing window (not shown). This makes it possible to accept editing such as registration and deletion of contract companies via the editing window.

[0083] 8, the distribution rate acquisition module 211 performs approval processing for the contract content information (S820). For example, the distribution rate acquisition module 211 accepts the contract content information from the general contractor terminal 103, and transmits an approval request notification to the construction company terminal 104. Furthermore, the distribution rate acquisition module 211 receives a response to the approval request.

[0084] As a result, the distribution rate acquisition module 211 can register, for example, a contractor who has approved the contract content information as a participating company contractor (construction participating company) in the IPD contract. In addition, the user of the contractor terminal 104 can approve the contract content information in response to the approval request notification, or can request the user of the general contractor terminal 103 to modify the contract content information.

[0085] When the contract content information is approved, the distribution rate acquisition module 211 displays, for example, a distribution condition information setting screen 1300 on the display of the general contractor terminal 103 and the construction company terminal 104 .

[0086] FIG. 13 shows an example of a distribution condition information setting screen 1300. Here, a screen displayed on the display of the general contractor terminal 103 is shown, but the same screen may also be displayed on the contractor terminal 104. The distribution condition information setting screen 1300 shown in the figure is a window including a project information area 1310, a display switching button group 1320, and a setting display area 1330. The project information area 1310 is the same as the project information area 1210 in FIG. 12.

[0087] For example, when the user presses the profit rate setting button 1322, the construction cost management module 216 displays an input interface for setting the profit rate in the setting display area 1330.

[0088] The setting display area 1330 displays participating company registration information 1350 and profit distribution ratio setting information 1360. In the profit distribution ratio setting information 1360, "Condition 1" for the distribution ratio setting is selected. This condition 1 indicates that if the construction profit amount is 5,000,000 yen, the distribution ratio to XY General Contractor Co., Ltd. is 70%, or 3,500,000 yen, and the distribution ratio to XXX Industrial Co., Ltd. is 30%, or 1,500,000 yen.

[0089] For example, condition 2, registered as a condition in the profit distribution ratio setting, states that "if the construction profit at the end of the construction is less than 3.5 million yen, the profit distribution ratio will be 50:50 between the general contractor and the construction company." When the terminal user selects condition 2 in the profit distribution ratio setting information 1360, the profit amount will be 3,000,000 yen.

[0090] The terminal user inputs distribution condition information and information related to the distribution rate to the profit distribution rate setting information 1360. For example, when the terminal user selects "Register condition details", the distribution amount output module 215 may superimpose a separate window for text input (not shown). This allows the terminal user to directly input the distribution ratio value or input the desired distribution amount, and also allows the terminal user to set the distribution ratio value by dragging the inverted triangular sliding object left and right.

[0091] For example, by clicking the "Approve" button 1390, an approval request for the distribution ratio based on the selected conditions is sent to the contractor terminal 104 via the management server 102. As a result, a response to the approval request is made at the contractor terminal 104, and when the contractor terminal 104 approves this approval request, the approved distribution ratio is registered.

[0092] 8, the distribution rate acquisition module 211 receives input of the distribution condition information and distribution rate mutually approved by the general contractor terminal 103 and the construction company terminal 104 (S830). Here, the distribution rate acquisition module 211 may receive updated input of the distribution rate from the general contractor terminal 103 and the construction company terminal 104.

[0093] Next, the distribution rate acquisition module 211 displays the input distribution condition information and distribution rate on the displays of the general contractor terminal 103 and the construction company terminal 104, displays an approval button, and requests approval of the distribution condition information and distribution rate (S840).

[0094] If the approval button is not pressed for a certain period of time (N: S840), the distribution rate acquisition module 211 requests approval of the distribution condition information and distribution rate again (S830). On the other hand, when approval is received from the general contractor terminal 103 and the construction company terminal 104 (Y: S840), the distribution rate acquisition module 211 confirms final approval as to whether or not to register the approved distribution condition information and distribution rate at the time of completion of construction work (S850). For example, the distribution rate acquisition module 211 displays a dialog box asking "Final registration of distribution condition information and distribution rate?" on the displays of the general contractor terminal 103 and the construction company terminal 104.

[0095] If final approval is not given for a certain period of time in S850 (N: S850), a request for approval of the distribution condition information and distribution ratio is made (S830). On the other hand, if final approval is given (Y: S850), the distribution ratio is determined, and the distribution ratio acquisition module 211 acquires this distribution ratio (S860). By the above distribution rate acquisition flow, for example, an IPD contract is concluded with the companies participating in the construction work, and the distribution rate of the construction profit to each participating company can be determined.

[0096] 1-3-3. Contract amount information acquisition flow 900 FIG. 9 shows an example of a contract amount information acquisition flow 900. Next, we will explain the contract amount information acquisition flow executed by the management server 102. In the contract amount information acquisition flow 900 shown in the figure, the management server 102 calculates contract amount information based on quantity information (contract quantity information) before construction work begins.

[0097] First, the contract amount information acquisition module 212 receives input of contract quantity information and contract unit price information from the general contractor terminal 103 (S910). The contract quantity information is quantity information at the time of the contract, i.e., before construction work begins. The contract unit price information is unit price information before construction work begins, and indicates unit prices for building materials, labor, etc., and is, for example, a composite unit price that combines these different unit prices.

[0098] The contract amount information acquisition module 212 may acquire contract quantity information, contract unit price information, and the like, for example, by using BIM data (contract BIM data) at the time of the IPD contract.

[0099] When the contract amount information acquisition module 212 receives input of the contract quantity information and the contract unit price information, it displays the contract quantity display screen 1400 on the displays of the general contractor terminal 103 and the construction company terminal 104 .

[0100] FIG. 14 is an example of a contract quantity display screen 1400. 14 shows an example of a display screen that is displayed when input of contract quantity information and contract unit price information is accepted. Here, the screen shown on the display of the general contractor terminal 103 is shown, but the same screen may also be displayed on the contractor terminal 104. The contract quantity display screen 1400 shown in the figure includes a project information area 1410, a display switching button area 1420, and a quantity information display area 1430.

[0101] Project information area 1410 is the same display as project information areas 1210 and 1310 described above. The display switching button area 1420 displays buttons for switching the information displayed in the quantity information display area 1430. For example, when the terminal user presses the contract quantity / list registration button 1421, the construction cost management module 216 displays the contract quantity information 221 in the quantity information display area 1430.

[0102] Also, for example, when the terminal user presses the work-unit-by-work-type list button 1422, the construction cost management module 216 displays contract work unit information in the quantity information display area 1430.

[0103] FIG. 15 is an example of a contract rate display screen 1500. Here, the screen displayed on the display of the general contractor terminal 103 is shown, but the same screen may also be displayed on the contractor terminal 104. The contract unit display screen 1500 shown in the figure includes a project information area 1510, a display switching button area 1520, and a quantity information display area 1530.

[0104] The project information area 1510 has the same display as the above-mentioned project information areas 1210, 1310, and 1410. Furthermore, the display switching button area 1520 displays the same buttons as the display switching button area 1420. For example, when the contract unit rate list button 1522 is selected, the construction cost management module 216 displays the contract unit rate information 223 including unit rate quantity information in the quantity information display area 1530 .

[0105] 9, the contract amount information acquisition module 212 calculates contract amount information based on the contract quantity information 221 and the contract unit rate information 223 (S920). The contract amount information is, for example, the total value by work type of the quantity information and unit rate information at the time of the contract, i.e., before the construction work is carried out (total contract amount).

[0106] Here, the contract amount information acquisition module 212 determines whether or not the quantity information has been changed or input in the contract quantity information 221 and the contract unit rate information 223. For example, the contract amount information acquisition module 212 determines whether or not the quantity information has been changed or input based on the difference from the last update of the file information of the contract quantity information 221 and the contract unit rate information 223.

[0107] Next, when information indicating a change in contract quantity information, contract unit price information, or contract price information (contract quantity change information) is received from the general contractor terminal 103 (Y: S930, S910), the contract amount information acquisition module 212 updates the contract amount information based on the contract quantity change information and calculates the contract amount information based on the updated contract quantity information and contract price information (S920).

[0108] If there are no new changes or inputs to the contract quantity information 221 and contract unit information 223 for a certain period of time (N: S930), the contract amount information acquisition module 212 performs approval processing for the contract quantity information 221 and contract unit information 223 (S940).

[0109] At this time, the contract amount information acquisition module 212 transmits an approval request to the general contractor terminal 103 and the construction company terminal 104 .

[0110] If there is no notification of approval from the general contractor terminal 103 or the construction company terminal 104 (N:S940), the contract amount information acquisition module 212 transmits an approval request to the general contractor terminal 103 and the construction company terminal 104. On the other hand, when approval is received from the general contractor terminal 103 and the construction company terminal 104 (Y: S940), the contract amount information acquisition module 212 calculates and acquires contract amount information based on the approved contract quantity information 221, contract work rate information 223, and unit price information (composite unit price) (S950).

[0111] 1-3-4. Acquisition of execution amount information flow 1000 Next, the flow of acquiring transaction amount information executed by the management server 102 will be described. FIG. 10 shows an example of a transaction amount information acquisition flow 1000. In the execution cost information acquisition flow 1000, the execution cost information acquisition module 213 of the management server 102 calculates and acquires execution cost information based on quantity information after construction work has started.

[0112] First, the construction cost information acquisition module 213 acquires quantity information and unit price information after the start or completion of construction (S1010).

[0113] The quantity information and unit price information after the start or completion of construction is, for example, quantity information and unit price information by type of work acquired from design information after the start of construction of the building work, etc. This quantity information and unit price information may be input by a terminal user of the general contractor terminal 103 or the contractor terminal 104 into an input screen of an app such as the general contractor terminal management module 311 or the contractor terminal management module 411.

[0114] The quantity information and unit price information after the start or completion of construction may be information automatically acquired from the BIM data (construction BIM data). Also, if there is a data change in the BIM data after the start (completion) of construction, the construction cost information acquisition module 213 may automatically acquire the quantity information and unit price information after the data change.

[0115] When the implementation amount information acquisition module 213 receives input of the implementation quantity information and implementation unit price information, it outputs and displays an implementation quantity display screen 1600 on the display of the general contractor terminal 103 or the construction company terminal 104 .

[0116] FIG. 16 is an example of an implementation quantity display screen 1600. Here, the screen displayed on the display of the general contractor terminal 103 is shown, but the same screen may also be displayed on the contractor terminal 104. The implementation quantity display screen 1600 shown in the figure includes a project information area 1610, a display switching button area 1620, and a quantity information display area 1630.

[0117] Project information area 1610 is the same display as the project information area in FIGS. The display switching button area 1620 displays buttons for switching the display in the quantity information display area 1630. For example, when the terminal user presses the implementation quantity / list registration button, the construction cost management module 216 displays the implementation quantity information 222 in the quantity information display area 1630.

[0118] The quantity information display area 1630 displays a BIM judgment button 1631, a display increase / decrease only button, an approval button, and the like. For example, when the terminal user presses the BIM judgment button 1631, the execution amount information acquisition module 213 reflects the quantity information (execution quantity) and construction unit price (unit price information) in the execution amount information 222 and the contract work rate information 223 based on the BIM data after the start of construction (completion of construction).

[0119] Also, for example, when the terminal user presses the button 1621 for listing units by implemented work type (actual work type), the construction cost management module 216 displays the contract unit information 223 in the quantity information display area 1430 .

[0120] FIG. 17 is an example of an execution rate display screen 1700. Here, the screen displayed on the display of the general contractor terminal 103 is shown, but the same screen may also be displayed on the contractor terminal 104. The work rate display screen 1700 includes a project information area 1710, a display switching button area 1720, and a quantity information display area 1730.

[0121] Project information area 1710 is the same display as the project information area in FIGS. The display switching button area 1720 displays the same buttons as the display switching button area 1620 (FIG. 16), and for example, an actual work type unit list button 1721 (actual work type unit list button) is selected. When the work type unit rate list button 1721 is selected, the construction cost management module 216 displays the work unit rate information 224 corresponding to the work type unit rate list button 1721 in the quantity information display area 1730 .

[0122] 10, the profit calculation module 214 calculates the implementation amount information (S1020) based on the implementation quantity information 222 and the implementation unit information 224. The implementation amount information is, for example, the total value (implementation quantity total value) by type of work of the quantity and implementation unit information at the time of construction or after construction is completed.

[0123] Here, the implementation amount information acquisition module 213 determines whether or not there is a change in the quantity information of the implementation quantity information 222 and the implementation unit information 224 (S1030). For example, the implementation amount information acquisition module 213 determines whether the implementation quantity information has been changed or input based on the difference between the implementation quantity information 222 and the implementation unit information 224 file information at the time of the last update.

[0124] Next, when the execution amount information acquisition module 213 receives information (execution amount change information) indicating a change in execution quantity information, execution unit information, or execution unit price information from the general contractor terminal 103 or the construction company terminal 104 (Y:S1030), it updates the contract amount information based on this.

[0125] In addition, the implementation amount information acquisition module 213 may acquire changes to the implementation quantity information (implementation quantity change information) that reflect the changes to the BIM data, for example, when there are changes to the BIM data (construction BIM data) after construction work has begun.

[0126] If there are no new changes or inputs to the implementation quantity information 222 and implementation unit information 224, or if there are no changes to the construction BIM data (N:S1030), the implementation amount information acquisition module 213 performs approval processing for the implementation quantity information 222 and implementation unit information 224 (S1040).

[0127] At this time, the execution amount information acquisition module 213 transmits an approval request to the general contractor terminal 103 and the construction company terminal 104 . When the execution cost information acquisition module 213 receives the notification of approval from the general contractor terminal 103 and the construction company terminal 104 (Y: S1040), it calculates and acquires the execution cost information based on the approved execution quantity information 222 and execution rate information 224, and the unit price information (composite unit price) (S1050). If approval is not granted, the execution cost information acquisition module 213 may, for example, continue to wait for the approval notification from the general contractor terminal 103 and the construction company terminal 104.

[0128] 1-3-5. Distribution output flow 1100 Next, the distribution amount output flow executed by the management server 102 will be described. FIG. 11 is an example of a distribution amount output flow 1100.

[0129] In a distribution amount output flow 1100, the management server 102 outputs the distribution amount calculated based on the construction profit amount.

[0130] First, the profit calculation module 214 acquires the total contract amount calculated by the contract amount information acquisition module 212 (S1110).

[0131] Next, the profit amount calculation module 214 acquires the total transaction amount calculated by the transaction amount information acquisition module 213 (S1120).

[0132] Next, the profit calculation module 214 calculates the construction profit (S1130). For example, the profit calculation module 214 calculates the difference between the acquired contract total amount and the implementation total amount as the construction profit of the building project.

[0133] The profit calculation module 214 may obtain the contract quantity information from the contract amount information and the implementation quantity information from the implementation amount information, and calculate the quantity difference value, which is the difference between them. In this case, the profit calculation module 214 may calculate the construction profit by multiplying the quantity difference value by the composite unit price based on the unit price information.

[0134] Next, the profit calculation module 214 acquires the distribution rate registered by the distribution rate acquisition module 211 (S1140), and calculates the profit distribution amount (distribution amount) to be distributed to each of the general contractor and the construction company by multiplying the construction profit amount by the distribution rate, and outputs it on the profit distribution amount display screen (S1150).

[0135] FIG. 18 is an example of a profit sharing amount display screen 1800. The profit distribution amount display screen 1800 is a screen that is displayed on the display of each of the general contractor terminal 103 and the construction company terminal 104. The profit distribution amount display screen 1800 includes a project information area 1810, a display switching button group 1820, and a distribution amount display area 1830. The display contents of the project information area 1810 are the same as those of the project information areas in each of FIGS.

[0136] When the user presses the "display profit amount" button 1821 of the display switching button group 1820, the distribution amount output module 215 displays the distribution amounts for the general contractor (XY General Contractor Co., Ltd.) and the construction company (XXX Industrial Co., Ltd.) in the distribution amount display area 1830.

[0137] For example, the distribution amount display area 1830 displays the calculated profit amount (4,200,000 yen), distribution amount information 1832, and distribution breakdown information 1834. The distribution amount information 1832 shows that the profit amount of 4,200,000 yen will be distributed as follows: 2,520,000 yen to the general contractor (XY General Contractor Co., Ltd.) and 1,680,000 yen to the construction company (XXX Industrial Co., Ltd.).

[0138] The distribution breakdown information 1834 shows the breakdown of the distribution amount. The distribution breakdown information 1834 shows that the profit amount of 4,200,000 yen, which is the difference between the amount at the time of contract and the amount at the time of completion of construction, will be distributed between XY General Contractor Co., Ltd. and XXX Industrial Co., Ltd. in a profit distribution ratio of 60%:40%.

[0139] In addition, depending on the relationship between the construction costs at the time of contract and the construction costs at the time of completion, there may be cases where the profit amount is negative.

[0140] FIG. 19 is an example of a profit sharing amount display screen 1900. The profit distribution amount display screen 1900 is a display screen for cases in which the profit amount is negative, and is a screen that is displayed on the displays of the general contractor terminal 103 and the construction company terminal 104. The profit distribution amount display screen 1900 includes a project information area 1910, a display switching button group 1920, and a distribution amount display area 1930, and the display contents of the project information area 1910 and the display switching button group 1920 are the same as those of the display switching button group 1820 in FIG.

[0141] The distribution amount display area 1930 displays distribution amount information 1932 and distribution breakdown information 1934. The distribution amount information 1932 indicates that the construction profit is -1,202,000 yen, and that the general contractor (XY General Contractor Co., Ltd.) will pay the full amount of 1,202,000 yen to the construction company (XXX Industrial Co., Ltd.).

[0142] According to the distribution amount output flow 1100 explained above, it is possible to output the distribution amount of the construction profit to be distributed to each of the construction participating companies (general contractors, construction companies) that have concluded an IPD contract. In addition, it is also possible to calculate and output the distribution amount in the case where the profit amount becomes negative based on the distribution conditions.
