Description

The present invention relates to an information management system, an information management method, and an information management program that support the management of the progress of construction work.

In construction work, many parts such as materials are used to create a structure. Such building parts are used at the construction site after going through a specified distribution process. Technology has been developed to record the traceability of such parts and enable workers to understand the distribution history of the parts (see, for example, Patent Document 1). In the technology disclosed in Patent Document 1, the worker provides a terminal computer with identification information for a specific part. In this case, corresponding distribution history data is sent from the host computer to the terminal computer, and the value of the distribution history data is displayed on the display device of the terminal. When the identification information of the candidate part at hand and the identification information of the specific part are entered into the terminal computer, a comparison result between the two is displayed on the display device.

JP 2019-99361 A

However, for parts used in construction, it is necessary to manage not only the distribution history but also the progress of the work, such as when the work is completed. Specifically, the contractor may be paid a contract fee (progress) corresponding to the completed portion (progress) according to the progress of the work. In this case, a progress inspection is carried out during the work, and the progress is calculated by converting the progress into a monetary value. In this progress inspection, the evaluation unit of the progress varies depending on the work content, and calculations are time-consuming.

The information management system for solving the above problem includes a BIM information storage unit that records BIM information including identification information of parts used in the construction work of a structure, and a control unit that is connected to a user terminal. The control unit executes a registration process in which it acquires identification information and performance status of parts and records them in the part information storage unit, and an output process in which it acquires search conditions related to the period, performance status, and part of the structure to be searched from the user terminal, identifies identification information of parts that correspond to the search conditions in the BIM information storage unit and have performance statuses that correspond to the search conditions in the part information storage unit, and totals quantities for calculating the progress of the construction work using quantities related to the configuration of the structure included in the BIM information of the parts.

The present invention makes it possible to efficiently manage the progress of construction work.

Below, an embodiment of an information management system, an information management method, and an information management program will be described with reference to Figures 1 to 19. In this embodiment, the information management system will be described as managing the progress status (degree of progress) of construction work. This degree of progress is an index showing the state of construction in the configuration of a structure. In this embodiment, the construction work is assumed to be the construction work of a building (structure).

For example, as shown in FIG. 18, part m1 used in the construction of structure a1 is manufactured in factory f1 (step S1) and stored in a storage area of factory f1. The part is then shipped by loading it onto a freight vehicle v1 (step S2) and transported from factory f1 to the construction site f2.

Part m1 is brought into the construction site f2 (step S3) and temporarily stored in a stockyard at the construction site f2. From this stockyard, it is transported to a work yard where construction is carried out using part m1. In the work yard, assembly work is carried out to assemble multiple parts as necessary.

Then, using a tower crane or the like, the part m1 is lifted from the work yard and the installation (construction) work of the part m1 is carried out (step S4). Furthermore, the part m1 used in the construction of the structure a1 is inspected (step S5).

To ensure traceability of part m1, each part is assigned unique identification information. Examples of unique identification information include a name, a serial number, or a manufacturing number.

In this embodiment, as shown in FIG. 19, a code image C1 is attached to the surface of part m1. The code image C1 is a one-dimensional code or a two-dimensional code, and for example, a QR code (registered trademark) can be used.

The code image C1 is an encoded version of unique identification information (unique code) assigned to the part m1. The code image C1 is attached to the part m1 during or after the manufacture of the part m1 in the factory f1. The part m1 to which the code image C1 is attached can be identified by the value of the code image C1, i.e., the unique code.
In this embodiment, as shown in FIG. 1, a user terminal 10 and a management server 20 are used which are connected via a network.

(Hardware configuration description)
2, the hardware configuration of the information processing device H10 constituting the user terminal 10 and the management server 20 will be described. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it is also possible to realize it using other hardware.

(System Configuration)
Next, each function of the information management system will be described with reference to FIG.
The user terminal 10 is a computer terminal used by a person in charge of managing the construction work. The user terminal 10 is equipped with a code reader. This code reader is a device that reads the code image C1 attached to the part m1. The user terminal 10 decodes and acquires the identification information (unique code) encoded in the code image C1 attached to the part m1.

The management server 20 is a computer system that supports the management of parts used at construction sites. This management server 20 includes a control unit 21, a BIM information storage unit 22, a part information storage unit 23, and a related information storage unit 24.

The control unit 21 assists in the management of parts used at the construction site. To this end, the control unit 21 functions as a design processing unit 211 by executing a design program. Furthermore, the control unit 21 functions as a parts management unit 212 by executing a parts management program.

The design processing unit 211 executes processing for creating Building Information Modeling (BIM) information using a BIM application.
The parts management unit 212 executes a process of registering information (group, planned date, file) of parts used in each process, and a process of confirming information about parts used at the construction site.

As shown in FIG. 3, the BIM information storage unit 22 records BIM information 220 created by a BIM application. This BIM information 220 is recorded when a building is designed using 3D CAD. The BIM information 220 includes a project code, a unique code, a product name, an element model, an arrangement, and attributes. A process code is associated with the BIM information 220.

The project code is an identifier for identifying each project (construction site).
The unique code is an identifier for identifying the elements (parts) used in this project.

The product name is the name of this element (part).
The element model is a three-dimensional model (object) of this element (part).
The location is information regarding the coordinates at which each element model is located.

The attributes are attribute information of this element (such as specifications, dimensions, weight, and materials). The attributes include a quantity 220a for evaluating the degree of progress for calculating the amount of work completed by the contractor. For example , the quantity 220a may be any of dimensions, weight, and volume or area calculated from the dimensions. The attributes also include information on the work area and the names of structural materials (for example, "2nd floor, work area A, floor", "3rd floor, work area B, wall", "3rd floor, work area C, column", etc.).
The process code is an identifier that identifies the current status of this element part in the distribution stage after it has been manufactured. It is blank in the initial state, and when this part is used in each process and begins to be distributed, an identifier indicating the current process ("Shipping", "Delivery", "Erection", "Inspection") is recorded.

As shown in FIG. 4, part information storage unit 23 records part management data 230. This part management data 230 is recorded when a process using a part is registered. Information related to the project code and unique code is recorded in part management data 230. Furthermore, information related to the process code, group code, planned date, and actual date is recorded for each distribution stage of the part.

The project code is an identifier for identifying each project (construction site).
The unique code is an identifier for identifying the elements (parts) used in this project.

The process code is an identifier for identifying the process in the distribution stage where the part is handled.
The group code is an identifier for identifying the group to which the part belongs. In this group, parts that are commonly handled, such as parts handled as a single unit as a part of a material or parts used in the same work area (floor, area), are grouped together.

The planned date is the date on which this part is scheduled to be used in the process at the distribution stage.
The performance date is the date on which this part was actually used in a process in the distribution stage. Here, the date on which the performance was registered using a two-dimensional code or the like is used. The performance status of this part can be specified by the process code (actual process) and the performance date.

As shown in FIG. 5, the related information storage unit 24 records related documents 240 related to parts. In this embodiment, the related documents 240 may be documents (electronic data) related to the construction work, and include files such as remarks information, images, drawings, quality control documents, labor-hour management information, and contract (unit price) information. The remarks information is a file in which comments about the parts entered by the person in charge (for example, the location of scratches) are recorded. The images are files of photos of the parts taken by the person in charge. The drawings are files of drawings of the parts (order drawings, completed drawings, etc.). The quality control documents are files in which the inspection results of the parts are recorded. The labor-hour management information records data on the evaluation unit for calculating the progress of the construction work according to the parts used in each process. For example, in the case of the interior of the wall, the evaluation unit is "square meters" because the evaluation is based on the area. In the case of concrete, the evaluation unit is "cubic meters" because the evaluation is based on the volume. The contract (unit price) information records data on unit prices for calculating the payment amount (output) according to the completed form. Management data 241 is associated with this related document 240. This management data 241 is used to classify the related document 240, and includes data on the project code, unique code, process code, and file type.

The project code is an identifier for identifying each project (construction site).
The unique code is an identifier for identifying the elements (parts) used in this project.

The process code is an identifier for identifying the process in which the related document 240 is registered. It is also possible to register the related document 240 without regard to the process. In this case, the process code is not recorded in the management data 241.
The file type is an identifier for identifying the type of the related document 240 related to this part.

(Initial registration process)
Next, the initial registration process S100 will be described with reference to FIG.

Here, first, the control unit 21 of the management server 20 executes the design process (step S101). Specifically, when designing a structure, the designer starts the design processing unit 211 of the control unit 21 by executing a BIM application. In this case, the design processing unit 211 outputs a CAD screen to the display device H13 of the user terminal 10. Then, the designer sets a project code and arranges three-dimensional models of each architectural element on the CAD screen to design the building. In this case, the design processing unit 211 sets attribute information (properties) of the architectural element for each element model. At this stage, the quantity 220a is also set. Then, when the design completion input is detected, the design processing unit 211 records the BIM information 220 in the BIM information storage unit 22. At this stage, the process code of the BIM information 220 is blank.

Then, the control unit 21 of the management server 20 executes a mode selection process (step S102). Specifically, when managing parts, the person in charge starts the parts management unit 212 by executing a parts management program.
In this case, a mode selection screen is output to the display device H13 of the user terminal 10.

As shown in FIG. 9, the mode selection screen 500 displays a project code input field, and the following selection buttons: "Manage," "Register," and "Confirm." The desired project code is input into the project code input field. "Manage" is a button for registering various information related to the part. "Register" is a button for registering the track record of the part at the distribution stage. "Confirm" is a button for confirming information related to the registered part. Here, the project code is input and the "Manage" button is selected.

Next, the control unit 21 of the management server 20 executes a process to obtain basic information (step S103). Specifically, the person in charge prepares in advance a basic information table for the parts to be used in the construction of the building. In the basic information table, the parts to be used in each process are grouped. Specifically, in the basic information table, the unique code of each part is associated with a process code, group code, and planned date. Each part is handled as a group of parts that are used collectively in each process by the process code and group code. Furthermore, in the basic information table, the planned date for using each part in each process is set.

Then, the parts management unit 212 of the control unit 21 outputs a data import screen to the display device H13 of the user terminal 10. On this data import screen, the person in charge specifies a basic information table that has been prepared in advance. As a result, the parts management unit 212 obtains the specified basic information table.

Next, the control unit 21 of the management server 20 executes a part information registration process (step S104). Specifically, the part management unit 212 of the control unit 21 generates part management data 230 that associates the process code, group code, and planned date of the basic information table with the project code and unique code of the BIM information 220, and records the data in the part information storage unit 23.

(Actual results registration process)
The performance record registration process S200 will be described with reference to Fig. 7. This process is executed when new performance information is to be registered for each part used in the construction. Here, the performance date at the distribution stage of the part and files related to the part are registered as new performance information.

First, the control unit 21 of the management server 20 executes a mode selection process (step S201), similar to step S102. Specifically, when registering new information about each component used in the construction, the user inputs a project code and selects the "Register" button on the mode selection screen 500 in FIG. 9.

Next, the control unit 21 of the management server 20 executes a process for outputting a registration designation screen (step S202). Specifically, the part management unit 212 of the control unit 21 outputs the registration designation screen to the display device H13 of the user terminal 10.

As shown in FIG. 10, a registration specification screen 510 is provided with a model display field 511 , a registration target setting field 512 , and a performance setting field 513 .
The part management unit 212 retrieves the element model of the specified project code from the BIM information storage unit 22 and displays the three-dimensional model in the model display field 511.

The registration target setting field 512 displays a setting field for specifying the parts for which actual results are to be registered. In this embodiment, it is possible to select "individual registration", in which each part is individually specified and registered, or "group registration", in which multiple parts are specified collectively and registered. For example, in "individual registration", the part with the searched unique code is specified as the registration target, and in "group registration", in the registration process, each part of the group to which the part with the searched unique code belongs is specified collectively as the registration target.

Furthermore, parts to be registered can be specified by using a code image or by keyword search. When using a code image, the code image attached to the part is read by a code reader. When searching by keyword, a character string included in the unique code or product name is entered as a search key.
It is also possible to select an element of the three-dimensional model displayed in the model display field 511 and make it a registration target.

In the results setting field 513, the results (process and date) of the part to be registered are set. Using the pull-down menu, one of the processes "Shipping", "Delivery", "Erection", or "Inspection" can be selected. "Shipping" is the button selected when a part is shipped from the factory. "Delivery" is the button selected when a part is delivered to a temporary storage location at the construction site. "Erection" is the button selected when construction is being carried out using parts. "Inspection" is the button selected when inspecting parts.

Here, a case will be described in which a part for which performance is to be registered is specified by reading a code image.
First, the user selects the code read button on the registration specification screen 510. In this case, the part management unit 212 of the control unit 21 starts up the code reader of the user terminal 10.

Then, as shown in FIG. 11, the part management unit 212 outputs a code capture screen 520 to the display device H13 of the user terminal 10. When the user terminal 10 recognizes the code image C1 on this code capture screen 520, it decodes the code image C1 to obtain a unique code.

Next, the control unit 21 of the management server 20 executes a search condition acquisition process (step S203). Specifically, the parts management unit 212 of the control unit 21 acquires the search conditions specified on the registration specification screen 510 from the user terminal 10. When an element of a three-dimensional model in the model display field 511 is selected, the unique code of the selected element of the three-dimensional model is acquired as the search condition. When a code image is used, the unique code obtained by decoded the code image C1 is acquired as the search condition. When a keyword search is performed, the search key entered on the registration specification screen 510 is acquired as the search condition.

Next, the control unit 21 of the management server 20 executes a search process (step S204). Specifically, the part management unit 212 of the control unit 21 searches for candidates for registration target parts in the part information storage unit 23 based on the search conditions. Then, the part management unit 212 creates a list that lists the identified candidate registration parts.

12, the performance registration screen 530 displays a process selection field 531, a performance date specification field 532, a search result list field 533, a remarks field 534, and a performance registration button. The process selection field 531 and the performance date specification field 532 are initially set to the process and date set in the performance setting field 513 of the registration specification screen 510. The search result list field 533 displays a list of candidates for parts to be registered as search conditions. For example, when one part is identified by a unique code read from a code image, one candidate is displayed.
In the remarks column 534, the person in charge can enter comments, if necessary.

Furthermore, the track record registration screen 530 is provided with a file registration field 535. In this file registration field 535, a file type can be specified and a file related to this part can be registered. When registering a file, the file can be dragged and dropped into the related documents field or the address of the save destination can be entered.
In addition, multiple part candidates belonging to a group may be extracted by "group registration," or multiple part candidates may be extracted by keyword search.
In this case, as shown in FIG. 13, a plurality of candidates are displayed on the achievement registration screen 530.

Next, the control unit 21 of the management server 20 executes a part selection process (step S205). Specifically, the check boxes in the search result list column 533 of the track record registration screen 530 are used to select the parts for which track record registration is to be performed. By selecting multiple check boxes, track record registration for multiple parts can be performed at once. Then, the part management unit 212 of the control unit 21 obtains the unique code of the part for which the check box is selected in the search result list column 533.

Next, the control unit 21 of the management server 20 executes an information update process (step S206). Specifically, when the parts management unit 212 of the control unit 21 detects the selection of the performance registration button, it identifies the parts management data 230 of the unique code of the selected part in the parts information storage unit 23. Then, the parts management unit 212 records the process code and performance date of the performance registration screen 530 in this parts management data 230. Furthermore, it updates the process code of the BIM information 220 in the BIM information storage unit 22 using the process code of this parts management data 230.

Furthermore, when a comment is input in the remarks field 534, the part management unit 212 associates the related document 240 (comment file) with the management data 241 (project code, unique code, process code, file type: remarks information) and records the related document 240 in the related information storage unit 24. Furthermore, when a related document is input in the file registration field 535, the part management unit 212 associates the related document 240 with the management data 241 (project code, unique code, process code, file type) and records the related document 240 in the related information storage unit 24.
Then, as shown in FIG. 14, in the model display field 511, the display form of the element 515 of the part whose performance has been registered is changed.

(Confirmation process)
The confirmation process S300 will be described with reference to Fig. 8. This process is executed when the status of each part used in a construction project is to be confirmed.

First, the control unit 21 of the management server 20 executes a mode selection process (step S301), similar to step S102. Specifically, when checking the status of each component used in the construction, the user inputs a project code on the mode selection screen 500 and selects the "Check" button.

Next, the control unit 21 of the management server 20 executes a confirmation screen display process (step S302). Specifically, the parts management unit 212 of the control unit 21 acquires an element model of the project code from the BIM information storage unit 22. Next, the parts management unit 212 acquires the planned date and actual date recorded in the parts information storage unit 23 for each element included in the 3D model. Then, the parts management unit 212 judges the progress status based on the difference in days between the planned date and the actual date as follows:

・Actual date - Planned date ≦ -5 days: Progress status "5 days or more ahead of schedule"
-5 days < Actual date - Planned date < 0 days: Progress status "Ahead of schedule"
・Actual date = Planned date: Progress status "As planned"
・0 days < Actual date - Planned date < 5 days: Progress status "Delay"
・5 days or less Actual date - Planned date: Progress status "Delay of 5 days or more"

Next, the part management unit 212 changes the display form of the elements of the three-dimensional model according to the determined progress status.
15, the parts management unit 212 outputs a progress status confirmation screen 540 to the display device H13 of the user terminal 10. In this progress status confirmation screen 540, the display form of the elements of the 3D model differs depending on the progress status. Note that parts whose results have not been registered are shown in a different display form (dashed lines). For example, the range in which the progress status is displayed becomes larger depending on the progress of the construction, such as the construction results status for February 541, the construction results status for March 542, and the construction results status for April 543.

Next, the control unit 21 of the management server 20 executes a process for acquiring search conditions (step S303). Specifically, the part management unit 212 of the control unit 21 outputs a search screen to the display device H13 of the user terminal 10.

As shown in FIG. 16, the search screen 550 includes a search method specification field 551, a display process specification field 552, a group specification field 553, a period specification field 554, a status specification field 555, and a progress calculation specification field 556 in order to specify the search target. In the search method specification field 551, a character string contained in a unique code or a keyword can be specified. In the display process specification field 552, the process to be displayed is specified according to the person in charge's preference. In the group specification field 553, the group to be displayed is specified according to the person in charge's preference. In the period specification field 554, the range of planned dates or actual dates (start date to end date) for the process to be displayed is specified according to the person in charge's preference. In the status specification field 555, the progress status of the process (ahead of schedule, on schedule, delayed) is specified according to the person in charge's preference.
In the progress calculation specification field 556, the part for which the progress is to be evaluated is specified according to the wishes of the person in charge. For example, keywords are entered to identify the work area or the composition of the structure (parts and materials used in the construction work), such as pillars, beams, walls, and ceilings. Furthermore, when evaluating the progress, the process and period are set according to the target in the period specification field 554. For example, in the case of shipping from a parts manufacturing factory, the process "shipment" is selected. In the case of construction of beams, pillars, floors, and walls, the process "construction" is selected. In this case, the period for which the progress is to be calculated is set according to the period.
Then, the parts management unit 212 of the control unit 21 acquires the search conditions input on the search screen 550 .

Next, the control unit 21 of the management server 20 executes a search process (step S304). Specifically, the parts management unit 212 of the control unit 21 searches for candidates for parts to be confirmed in the BIM information storage unit 22 and the parts information storage unit 23 based on the acquired search conditions. Furthermore, the parts management unit 212 acquires, for each confirmation candidate part, history information (planned date, actual date) of the process specified in the display process specification field 552 from the parts information storage unit 23. Then, the parts management unit 212 determines the progress status from the difference in days between the planned date and the actual date (difference status).

Next, the control unit 21 of the management server 20 executes a calculation process of the degree of progress (step S305). Specifically, the part management unit 212 of the control unit 21 uses the man-hour management information recorded in the related information storage unit 24 to identify the evaluation unit for calculating the degree of progress according to the part for which the degree of progress is to be calculated. For example, when the degree of progress is evaluated by volume, such as for pillars, beams, floors, and walls, "cubic meters" are used as the evaluation unit. When the degree of progress is evaluated by area, such as for interior parts such as ceilings, "square meters" are used as the evaluation unit. Then, the part management unit 212 totals the quantity according to the evaluation unit using the attribute information of the parts to be confirmed from the BIM information storage unit 22. For example, when the parts to be confirmed are "2nd floor" and "floor", the BIM information related to "2nd floor" and "floor" is obtained from the BIM information storage unit 22, and the volume of the completed form is totaled using the dimensions of the attribute information.

Next, the parts management unit 212 specifies the unit price according to the progress calculation target by using the contract (unit price) information recorded in the related information storage unit 24. Then, the parts management unit 212 multiplies the unit price by the quantity to calculate the amount (output).
Furthermore, the parts management unit 212 calculates the quantity (volume) of the completed parts for each month for the representative structural materials "columns,""beams,""floors," and "walls" in this project. Furthermore, it calculates the ratio of the completed parts for each month to the total quantity of the structural materials "columns,""beams,""floors," and "walls" in this project.

Next, the control unit 21 of the management server 20 executes an output process of the calculation result (step S306). Specifically, the part management unit 212 of the control unit 21 outputs a progress confirmation screen to the display device H13 of the user terminal 10.

17, the part management unit 212 outputs a progress confirmation screen 560. The progress confirmation screen 560 includes a progress confirmation field 561 and a progress confirmation graph 562. The progress confirmation field 561 displays the evaluation unit, unit price, quantity, and amount used to calculate the progress of the progress calculation target.
The progress confirmation graph 562 also displays a graph of the completed state at each stage. A stacked bar graph of the completed amount (volume) for each month is displayed for the representative structural materials "columns,""beams,""floors," and "walls." Furthermore, a line graph showing the ratio of the completed state to the total amount of the structural materials "columns,""beams,""floors," and "walls" of this project is displayed.

According to this embodiment, the following effects can be obtained.
(1) In this embodiment, the control unit 21 of the management server 20 executes a process of outputting a registration specification screen (step S202) and a process of acquiring search conditions (step S203). When a code image is used, the code image attached to the part is read by a code reader. This makes it possible to efficiently acquire a unique code and register the performance status of the part at the distribution stage.

The parts management unit 212 also retrieves the element model of the specified project code from the BIM information storage unit 22 and displays the three-dimensional model in the model display field 511. This allows the performance status of the parts at the distribution stage to be input using the three-dimensional model created by the BIM application.

(2) In this embodiment, the performance registration screen 530 is provided with a file registration field 535. This allows files created at each process in the distribution stage of parts to be managed for each part. In particular, by registering them in association with elements created by the BIM application, it is possible to centrally manage the process from design to completion of construction.

(3) In this embodiment, the control unit 21 of the management server 20 executes a part selection process (step S205). Specifically, the parts for which the track record is to be registered are selected using the check boxes in the search result list field 533 on the track record registration screen 530. This allows track record registration of multiple parts to be performed at the same time.

(4) In this embodiment, parts management data 230 is recorded in the parts information storage unit 23. Information relating to the project code and unique code is recorded in the parts management data 230. Furthermore, information relating to the process code, group code, planned date, and performance date is recorded for each distribution stage of the parts. This makes it possible to identify commonly handled parts at once. In particular, when commonly handled parts differ depending on the process, it is possible to identify parts belonging to a group depending on the process.
(5) In this embodiment, the control unit 21 of the management server 20 executes a confirmation screen display process (step S302). This allows the progress of each part to be confirmed in the three-dimensional model created by the BIM application.

(6) In this embodiment, the control unit 21 of the management server 20 executes a process for acquiring search conditions (step S303). The search screen 550 includes a search method specification field 551 to a progress calculation specification field 556. By using the display process specification field 552, the user can select the process to be confirmed and check the status. By using the group specification field 553, the user can specify all the parts that are handled together in the distribution stage and check the status. By using the period specification field 554, the user can identify the parts according to the range of the planned or actual dates (start date to end date) for the process to be displayed and check the status. By using the status specification field 555, the user can identify the parts according to the progress status of the process (ahead of schedule, on schedule, delayed) and check the status.

(7) In this embodiment, the control unit 21 of the management server 20 executes a process of calculating the degree of progress (step S306) and a process of outputting the calculation results (step S307). This allows the desired degree of progress to be confirmed according to the progress status. Therefore, the on-site staff can efficiently check the contractor's invoices (monthly). In addition, the construction progress status can be confirmed by a graph showing the completed form at each time point.

This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.
In the above embodiment, BIM information is used in the construction work of a building. The application of this embodiment is not limited to construction work. That is, the BIM of this embodiment is a technology including CIM (Construction Information Modeling) used in construction design of civil engineering, etc.

- In the above embodiment, the control unit 21 of the management server 20 executes a search process (step S204). The track record registration screen 530 is provided with a file registration field 535. Here, the file type is registered. Alternatively, the control unit 21 of the management server 20 may identify the file type. In this case, the file type is identified based on the related document 240 to be registered. For example, a code image for identifying the file type may be attached to the related document 240, and this code image may be decoded. The control unit 21 may also identify the file type based on text or images contained in the related document 240.

- In the above embodiment, the parts information storage unit 23 records parts management data 230. This parts management data 230 records history information (planned date, actual date). Information included in the history information is not limited to the actual date. For example, information identifying the person who performed the work at each process (worker code), the work location of each process (factory name), the equipment used at each process (e.g., vehicle number), etc. may be recorded. In this case, the worker code may be identified by login information to the user terminal 10, or the work location may be identified by the location information acquisition means (GNSS, etc.) of the user terminal 10. In addition, the user terminal 10 may communicate with the equipment (e.g., vehicle) used in each process to identify the identification information of the equipment.

- In the above embodiment, "shipping," "delivery," "construction," and "inspection" are recorded as processes in the distribution stage, but the processes are not limited to these. For example, the processes may include "assembly," "welding," "delivery," etc.

In the above embodiment, the related information storage unit 24 records related documents 240 related to parts. The related documents include files of remarks, images, drawings, quality control documents, etc. The related documents may be documents (electronic data) related to construction work, and may include construction plans, construction meeting records, holiday work notifications, construction approval request records, etc.
Alternatively, the related documents 240 may be recorded in another file server, and information indicating the storage destination of the related documents 240 (e.g., an address) may be recorded in the related information storage unit 24. In this case, the address of the file storage destination is input in the file registration field 535 of the track record registration screen 530. Then, in the related document display process (step S306), the storage destination address is used to obtain the related documents 240 from the file server.

- In the above embodiment, a code image C1 is attached to the surface of part m1. Here, instead of the code image C1, a character string or an IC tag may be attached to part m1. The character string represents a unique code assigned to part m1. The IC tag is an electronic device (e.g., RFID) that stores the unique code assigned to part m1 and transmits it via short-range wireless communication.

In the above embodiment, "square meters" and "cubic meters" are used as the evaluation units. The evaluation units are not limited to these as long as they are indicative of the state of construction of a structure. For example, the rate of completion of the structure may be used. Furthermore, when evaluating the degree of progress by weight, such as with rebar, "tons" can be used as the evaluation unit.
In the case of materials contained in parts such as concrete and reinforcing bars, the composition ratio of the material (for example, reinforcing bar ratio) is used for the BIM information of each part. In the case of concrete, the quantity (volume) of the part for which the construction results are registered is calculated. In the case of reinforcing bars, the part management unit 212 obtains the weight from the attribute information of the BIM information of the part, multiplies it by the composition ratio, and calculates the quantity (reinforcing bar weight). The weight may also be calculated from the volume. In this case, an index indicating the amount of reinforcing bar used relative to the size of the material [weight of reinforcing bar/volume of component] is used as the composition ratio of the material.
In the above embodiment, the control unit 21 of the management server 20 executes a process of calculating the degree of progress (step S306) and a process of outputting the calculation result (step S307). Here, the amount may be adjusted according to the progress status. For example, if a late fee is set in the contract information according to a delay of a predetermined number of days or more, the parts management unit 212 adjusts the amount of work by deducting the late fee based on the contract information according to the progress status (e.g., the delay status).
