Description

Technical Field

[0001] The present invention relates to an information management system, an information management method, and an information management program for assisting in the management of the progress of construction work.

Background Art

[0002] In construction work, a building is constructed using many parts such as materials. Such parts of the building are used at the construction site through a predetermined distribution process. Technologies for recording the traceability of such parts and for workers to grasp the distribution history of the parts have been studied (see, for example, Patent Document 1). In the technology disclosed in this Patent Document 1, a worker gives identification information of a specific part to a terminal computer. In this case, the corresponding distribution history data is transmitted 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 input to the terminal computer, the comparison result of the two is displayed on the display device.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, for the parts used in construction, it is necessary to manage not only the distribution history but also the output such as the completion of the work. Specifically, the contractor for the construction work is paid the contract price (output) corresponding to the completed part (completed form) according to the progress of the object of the work. u This may happen. In this case, an output inspection is performed during the construction, and the output obtained by converting the completed form into an amount is calculated. In this output inspection, the evaluation unit of the completed form differs depending on the construction content of the work, and the calculation is time-consuming.

Means for Solving the Problem

[0005] The information management system for solving the above problems 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 connected to a user terminal. Then, the control unit performs a registration process of acquiring the identification information and performance status of the parts and recording them in the parts information storage unit, and acquires from the user terminal a search period, a performance status, and search conditions related to the part of the structure, and identifies, in the BIM information storage unit, the parts corresponding to the search conditions and the identification information of the parts with the performance status corresponding to the search conditions in the parts information storage unit, and totals the quantities for calculating the progress of the construction work using the quantities related to the structure composition included in the BIM information of the parts, and executes an output process.

Effect of the Invention

[0006] According to the present invention, the progress of the construction work can be efficiently managed.

Mode for Carrying Out the Invention

[0008] Hereinafter, an embodiment of an information management system, an information management method, and an information management program will be described with reference to FIGS. 1 to 19. In this embodiment, it will be described as an information management system for managing the progress status (progress degree) of construction work. This progress degree is an index indicating the way of construction in the structure of the structure. Further, in this embodiment, building construction of a building (structure) is assumed as the construction work.

[0009] For example, as shown in FIG. 18, the component m1 used in the construction of the structure a1 is manufactured at the factory f1 (step S1) and stored in the storage location of the factory f1. Then, the component is shipped by loading it onto the freight car v1 (step S2) and transported from the factory f1 to the construction site f2.

[0010] The component m1 is carried into the construction site f2 (step S3) and temporarily stored in the stockyard of the construction site f2. From this stockyard, it is transported to the work yard where construction is carried out using the component m1. In the work yard, groundwork operations for assembling a plurality of components are carried out as necessary.

[0011] Then, using a tower crane or the like, the component m1 is lifted from the work yard, and the installation (construction) work of the component m1 is performed (step S4). Further, the component m1 used in the construction of the structure a1 is inspected (step S5).

[0012] To realize the traceability of this component m1, unique identification information is assigned to each component. As the unique identification information, for example, a name, a serial number, a manufacturing number, or the like is used.

[0013] In the present embodiment, as shown in FIG. 19, a code image C1 is attached to the surface of the component 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.

[0014] The code image C1 encodes the unique identification information (unique code) assigned to the component m1. The code image C1 is attached to the component m1 during or after the manufacture of the component m1 at the factory f1. The component m1 to which the code image C1 is attached can be identified by the value of the code image C1, that is, the unique code. In the present embodiment, as shown in FIG. 1, a user terminal 10 and a management server 20 connected via a network are used.

[0015] (Description of Hardware Configuration) Using FIG. 2, the hardware configuration of the information processing apparatus H10 that constitutes the user terminal 10 and the management server 20 will be described. The information processing apparatus 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 be realized by other hardware.

[0016] The communication device H11 is an interface that establishes a communication path with other devices and executes data transmission and reception, and is, for example, a network interface or a wireless interface.

[0017] The input device H12 is a device that accepts the input of various information, such as a mouse, a keyboard, etc. The display device H13 is a display or the like that displays various information. The storage device H14 stores data and various programs for executing various functions of the user terminal 10 and the management server 20. Examples of the storage device H14 include a ROM, a RAM, a hard disk, etc.

[0018] The processor H15 controls each process in the user terminal 10 and the management server 20 using the programs and data stored in the storage device H14. Examples of the processor H15 include, for example, a CPU, an MPU, etc. This processor H15 expands the program stored in a ROM or the like to the RAM and executes various processes for each process.

[0019] The processor H15 is not limited to performing software processing for all processes it executes. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application-specific integrated circuit: ASIC) that performs hardware processing for at least a part of the processes it executes. That is, the processor H15 may be configured as follows. [1] One or more processors that operate according to a computer program (software) [2] One or more dedicated hardware circuits that execute at least a part of various processes [3] A combination thereof, including circuitry The processor includes a CPU and memories such as a RAM and a ROM, and the memories store program codes or instructions configured to cause the CPU to execute processes. The memory, that is, the computer-readable medium, includes any available medium accessible by a general-purpose or dedicated computer.

[0020] (System Configuration) Next, each function of the information management system will be described with reference to FIG. 1. The user terminal 10 is a computer terminal used by the person in charge of managing 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 component m1. The user terminal 10 decodes and acquires the identification information (unique code) encoded in the code image C1 attached to the component m1.

[0021] The management server 20 is a computer system that supports the management of components used at the construction site. This management server 20 includes a control unit 21, a BIM information storage unit 22, a component information storage unit 23, and a related information storage unit 24.

[0022] The control unit 21 supports the management of components used at the construction site. For this purpose, the control unit 21 functions as a design processing unit 211 by executing a design program. Furthermore, the control unit 21 functions as a component management unit 212 by executing a component management program.

[0023] The design processing unit 211 executes a process of creating BIM information by a BIM (Building Information Modeling) application. The component management unit 212 executes a registration process of information (group, planned date, file) of components used in each process and a confirmation process of information regarding components used at the construction site.

[0024] 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 the building is designed using 3D CAD. The BIM information 220 is composed of a project code, a unique code, a product name, an element model, an arrangement, and an attribute. A process code is associated with the BIM information 220.

[0025] The project code is an identifier for identifying each project (construction site). The unique code is an identifier for identifying the elements (components) used in this project.

[0026] The product name is the name of this element (part). The element model is the 3D model (object) of this element (part). The arrangement is information regarding the coordinates for arranging each element model.

[0027] The attribute is the attribute information (specifications, dimensions, weight, material, etc.) of this element. This attribute includes the quantity 220a for evaluating the progress for calculating the output by the constructor. For example As the quantity 220a, any of dimensions, weight, volume or area calculated from dimensions, etc. can be used. Further, this attribute includes information regarding the work area and the name of the structural material (e.g., "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 for specifying the current situation in the distribution stage when this element part is manufactured. It is blank in the initial state, and when this part starts to be used and distributed in each process, an identifier indicating the current process ("shipment", "loading", "construction", "inspection") is recorded.

[0028] As shown in FIG. 4, in the part information storage unit 23, part management data 230 is recorded. This part management data 230 is recorded when registration of the process using the part is performed. Information regarding the project code and the unique code is recorded in the part management data 230. Further, information regarding the process code, group code, planned date, and actual date is recorded for each distribution stage of this part.

[0029] The project code is an identifier for specifying each project (construction site). The unique code is an identifier for specifying the element (part) used in this project.

[0030] The process code is an identifier for specifying the process in the distribution stage where the part is handled. The group code is an identifier for specifying the group to which the part belongs. In this group, parts that are commonly handled, such as parts that are handled integrally as parts of materials, or parts used in the same work area (floor, region), are grouped together.

[0031] The planned date is the year, month, and day on which this part is scheduled to be used in the processes of the distribution stage. The actual date is the year, month, and day on which this part was actually used in the processes of the distribution stage. Here, the year, month, and day on which the actual results were registered using a 2D code or the like are used. The process code (actual process) and the actual date can identify the actual situation of this part.

[0032] As shown in FIG. 5, related document storage unit 24 stores related documents 240 related to the parts. In this embodiment, the related documents 240 may be documents (electronic data) related to construction work, and include files such as remarks information, images, drawings, quality control documents, man-hour management information, contract (unit price) information, etc. The remarks information is a file in which comments (for example, the location of scratches) related to the parts input by the person in charge are recorded. The image is a file of a photo related to the parts taken by the person in charge. The drawings are files of the 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 man-hour management information records data related to 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 interior wall decoration, "square meter" is used as the evaluation unit for evaluation by area. In the case of concrete, "cubic meter" is used as the evaluation unit for evaluation by volume. The contract (unit price) information records data related to the unit price for calculating the payment amount (quantity produced) according to the completed form. Management data 241 is associated with these related documents 240. This management data 241 is used for classifying the related documents 240 and includes data related to the project code, unique code, process code, and file type.

[0033] The project code is an identifier for specifying each project (construction site). The inherent code is an identifier for specifying elements (parts) used in this project.

[0034] The process code is an identifier for specifying the process in which the related document 240 is registered. Note that it is also possible to register the related document 240 regardless of the process. In this case, the process code is not recorded in the management data 241. The file type is an identifier for specifying the type of the related document 240 related to this part.

[0035] (Initial registration process) Next, the initial registration process S100 will be described with reference to FIG. 6.

[0036] Here, first, the control unit 21 of the management server 20 executes a design process (step S101). Specifically, when designing a structure, the person in charge 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 person in charge sets a project code and arranges 3D models of each building element on the CAD screen to design the building. In this case, the design processing unit 211 sets attribute information (properties) of the building element for each element model. At this stage, the quantity 220a is also set. When the completion input of the design 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.

[0037] Then, the control unit 21 of the management server 20 executes a mode selection process (step S102). Specifically, when performing part management, the person in charge starts the part management unit 212 by executing a part management program. In this case, a mode selection screen is output to the display device H13 of the user terminal 10.

[0038] As shown in FIG. 9, on the mode selection screen 500, a project code input field and selection buttons for "Management", "Registration", and "Confirmation" are displayed. Enter the desired project code in the project code input field. "Management" is a button for registering various information regarding parts. "Registration" is a button for registering the performance in the distribution stage regarding parts. "Confirmation" is a button for checking the information regarding the registered parts. Here, enter the project code and select the "Management" button.

[0039] Next, the control unit 21 of the management server 20 executes basic information acquisition processing (step S103). Specifically, the person in charge prepares a basic information table in advance for the parts used in the construction of the building. In the basic information table, the parts used in each process are grouped. Specifically, in the basic information table, a process code, a group code, and a planned date are associated with the unique code of each part. Each part is handled collectively as a group of parts (group) used in a batch in each process according to the process code and the group code. Further, in the basic information table, the planned date when each part is used is set for each process.

[0040] 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 designates the basic information table prepared in advance. Thereby, the parts management unit 212 acquires the designated basic information table.

[0041] Next, the control unit 21 of the management server 20 executes parts information registration processing (step S104). Specifically, the parts management unit 212 of the control unit 21 generates parts management data 230 in which the process code, group code, and planned date of the basic information table are associated with the project code and unique code of the BIM information 220, and records it in the parts information storage unit 23.

[0042] (Performance registration processing) Using FIG. 7, the achievement registration process S200 will be described. This process is executed when registering new achievement information for each component used in construction. Here, as the new achievement information, the achievement date at the distribution stage of the component and the files related to the component are registered.

[0043] First, the control unit 21 of the management server 20 executes a mode selection process in the same manner as in step S102 (step S201). Specifically, when registering new information for each component used in construction, on the mode selection screen 500 in FIG. 9, the project code is input and the "Register" button is selected.

[0044] Next, the control unit 21 of the management server 20 executes an output process for the registration designation screen (step S202). Specifically, the component management unit 212 of the control unit 21 outputs the registration designation screen to the display device H13 of the user terminal 10.

[0045] As shown in FIG. 10, the registration designation screen 510 is provided with a model display column 511, a registration target setting column 512, and an achievement setting column 513. The component management unit 212 acquires the element model of the designated project code from the BIM information storage unit 22 and displays the 3D model in the model display column 511.

[0046] In the registration target setting column 512, a setting column for specifying the component for which achievement registration is to be performed is displayed. In this embodiment, it is possible to select "individual registration" for specifying each component individually for registration, or "group registration" for specifying and registering a plurality of components together. For example, in "individual registration", the component with the searched unique code is specified as the registration target, and in "group registration", in the registration process, each component of the group to which the component with the searched unique code belongs is collectively specified as the registration target.

[0047] Furthermore, the 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. In keyword search, the strings included in the unique code or product name are entered as search keys. It is also possible to select the elements of the 3D model displayed in the model display field 511 and register them.

[0048] In the performance setting field 513, the performance (process and date) of the parts to be registered is set. By using a pull-down menu, any one of the processes "shipment", "incoming", "construction", and "inspection" can be selected. "Shipment" is a button selected when the part is shipped from the factory. "Incoming" is a button selected when the part is brought into the temporary storage location at the construction site. "Construction" is a button selected during the construction using the part. "Inspection" is a button selected during the inspection of the part.

[0049] Here, the case of specifying the parts to be registered by reading the code image will be described. First, the code reading button on the registration specification screen 510 is selected. In this case, the parts management section 212 of the control section 21 activates the code reader of the user terminal 10.

[0050] Then, as shown in FIG. 11, the parts management section 212 outputs a code capture screen 520 to the display device H13 of the user terminal 10. On this code capture screen 520, when the user terminal 10 recognizes the code image C1, the code image C1 is decoded to obtain the unique code.

[0051] Next, the control unit 21 of the management server 20 executes a search condition acquisition process (step S203). Specifically, the component 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 the 3D model in the model display column 511 is selected, the unique code of the selected 3D model element is acquired as a search condition. In the case of using a code image, the unique code obtained by decoding the code image C1 is acquired as a search condition. In the case of a keyword search, the search keyword input on the registration specification screen 510 is acquired as a search condition.

[0052] Next, the control unit 21 of the management server 20 executes a search process (step S204). Specifically, the component management unit 212 of the control unit 21 searches for candidates for parts to be registered in the parts information storage unit 23 based on the search conditions. Then, the component management unit 212 creates a list of the identified registration candidate parts.

[0053] As shown in FIG. 12, on the performance registration screen 530, a process selection column 531, a performance date specification column 532, a search result list column 533, a remarks column 534, and a performance registration button are displayed. The process and date set in the performance setting column 513 of the registration specification screen 510 are initially set in the process selection column 531 and the performance date specification column 532. A list of candidates for parts to be registered according to the search conditions is displayed in the search result list column 533. For example, when one part is identified by the unique code read from the code image, one candidate is displayed. In the remarks column 534, the comments of the person in charge can be input as necessary.

[0054] Furthermore, a file registration column 535 is provided on the performance registration screen 530. In this file registration column 535, the file type can be specified, and files related to this part can be registered. When registering a file, the file can be dragged and dropped into the related documents column, or the storage destination address can be input. Also, there may be cases where a plurality of part candidates belonging to a group are extracted by "group registration" or a plurality of part candidates are extracted by keyword search. In this case, as shown in FIG. 13, a plurality of candidates are output on the performance registration screen 530.

[0055] Next, the control unit 21 of the management server 20 executes a component selection process (step S205). Specifically, using the check boxes in the search result list column 533 of the performance registration screen 530, the components for which performance registration is to be performed are selected. By selecting a plurality of check boxes, performance registration of a plurality of components can be performed in a batch. Then, the component management unit 212 of the control unit 21 acquires the unique code of the component of the check box selected in the search result list column 533.

[0056] Next, the control unit 21 of the management server 20 executes an information update process (step S206). Specifically, when the component management unit 212 of the control unit 21 detects the selection of the performance registration button, it identifies the component management data 230 of the unique code of the selected component in the component information storage unit 23. Then, the component management unit 212 records the process code and performance date of the performance registration screen 530 in this component management data 230. Further, using the process code of this component management data 230, the process code of the BIM information 220 in the BIM information storage unit 22 is updated.

[0057] Also, when a comment is entered in the remarks column 534, the component management unit 212 records the related document 240 (comment file) in the related information storage unit 24 in association with the management data 241 (project code, unique code, process code, file type: remarks information). Further, when a related document is entered in the file registration column 535, the component management unit 212 records the related document 240 in the related information storage unit 24 in association with the management data 241 (project code, unique code, process code, file type). Then, as shown in FIG. 14, in the model display column 511, the display form of the element 515 of the component for which the performance has been registered is changed.

[0058] (Confirmation process) Using FIG. 8, the confirmation process S300 will be described. This process is executed when checking the status of each component used in the construction.

[0059] First, the control unit 21 of the management server 20 executes a mode selection process in the same manner as in step S102 (step S301). Specifically, when checking the status of each component used in the construction, on the mode selection screen 500, the project code is input and the "confirmation" button is selected.

[0060] Next, the control unit 21 of the management server 20 executes a confirmation screen display process (step S302). Specifically, the component management unit 212 of the control unit 21 acquires the element model of the project code from the BIM information storage unit 22. Next, for each element included in the 3D model, the component management unit 212 acquires the planned date and the actual date recorded in the component information storage unit 23. Then, the component management unit 212 determines the progress status as follows based on the difference days between the planned date and the actual date.

[0061] · Actual date - Planned date ≤ -5 days: Progress status "advanced by more than 5 days" · -5 days < Actual date - Planned date < 0 days: Progress status "advanced" · Actual date = Planned date: Progress status "as planned" · 0 days < Actual date - Planned date < 5 days: Progress status "delayed" · 5 days ≤ Actual date - Planned date: Progress status "delayed by more than 5 days"

[0062] Next, the component management unit 212 changes the display form of the elements of the 3D model according to the determined progress status. Then, as shown in FIG. 15, the component management unit 212 outputs a progress status confirmation screen 540 to the display device H13 of the user terminal 10. On this progress status confirmation screen 540, the display forms of the elements of the 3D model are different according to the progress status. Note that components for which no actual results have been registered are indicated in a different display form (dashed line). For example, like the building construction actual status 541 in February, the building construction actual status 542 in March, and the building construction actual status 543 in April, the range in which the progress status is displayed becomes larger according to the progress of the construction work.

[0063] Next, the control unit 21 of the management server 20 executes a search condition acquisition process (step S303). Specifically, the component management unit 212 of the control unit 21 outputs a search screen to the display device H13 of the user terminal 10.

[0064] As shown in FIG. 16, the search screen 550 includes a search method specification column 551, a display process specification column 552, a group specification column 553, a period specification column 554, a status specification column 555, and a progress calculation specification column 556 in order to specify a search target. In the search method specification column 551, a character string included in a unique code or a keyword can be specified. In the display process specification column 552, the process to be displayed can be specified according to the wishes of the person in charge. In the group specification column 553, the group to be displayed can be specified according to the wishes of the person in charge. In the period specification column 554, according to the wishes of the person in charge, for the process to be displayed, the range of the planned date or actual date (start date to end date) is specified. In the status specification column 555, according to the wishes of the person in charge, the progress status (ahead of schedule, on schedule, behind schedule) of the process is specified. In the progress calculation specification column 556, according to the wishes of the person in charge, the target component for evaluating the progress is specified. For example, keywords for specifying the composition of a work area or structures such as columns, beams, walls, and ceilings (components and materials used in construction work) are input. Further, when evaluating the progress, in the period specification column 554, the process and period are set according to the target. For example, in the case of the shipment from the component manufacturing factory, the process "shipment" is selected. In the case of the construction of beams, columns, floors, and walls, the process "construction" is selected. In this case, the period for calculating the progress is set according to the period. Then, the component management unit 212 of the control unit 21 acquires the search conditions input on the search screen 550.

[0065] Next, the control unit 21 of the management server 20 executes a search process (step S304). Specifically, the component management unit 212 of the control unit 21 searches for candidates of the parts to be confirmed in the BIM information storage unit 22 and the component information storage unit 23 based on the obtained search conditions. Further, the component management unit 212 acquires, from the component information storage unit 23, the history information (planned date, actual date) of the process specified in the display process designation column 552 for each confirmation candidate part. Then, the component management unit 212 determines the progress status from the number of days of difference (difference status) between the planned date and the actual date.

[0066] Next, the control unit 21 of the management server 20 executes a progress calculation process (step S305). Specifically, the component management unit 212 of the control unit 21 specifies an evaluation unit for calculating the progress according to the part for which the progress is to be calculated, using the man-hour management information recorded in the related information storage unit 24. For example, when evaluating the progress by volume, such as columns, beams, floors, and walls, "cubic meters" is used as the evaluation unit. When evaluating the progress by area, such as interior finishes of ceilings, etc., "square meters" is used as the evaluation unit. Then, the component management unit 212 totals the quantity according to the evaluation unit, using the attribute information of the part to be confirmed from the BIM information storage unit 22. For example, when the part to be confirmed is the "2nd floor" and "floor", the BIM information related to the "2nd floor" and "floor" is acquired from the BIM information storage unit 22, and the volume of the completed form is totaled using the dimensions of the attribute information.

[0067] Next, the component management unit 212 specifies the unit price using the contract (unit price) information recorded in the related information storage unit 24 according to the part for which the progress is to be calculated.
