Description

[Technical field]

[0001] The present disclosure relates to a work area management system, a work area management method, and a work area management program for managing work areas in construction. [Background technology]

[0002] In construction work, concrete is often poured at a construction site. When pouring concrete, the area where concrete is poured is divided, and this area is assigned as a construction unit (work section). A technique for grasping the amount of concrete poured for each work section has been considered (for example, see Patent Document 1). The pouring plan support device disclosed in Patent Document 1 includes a model storage unit that stores shape information on the three-dimensional shape of concrete components that constitute a building. Then, a skeleton diagram is drawn based on the shape information, and the skeleton diagram is divided into a plurality of regions according to an input from a user. Furthermore, for each region, a component at least a part of which is included in the region is identified. Next, at least a part of the identified component that is included in the region is identified. The volume of the identified at least part is calculated, and the calculated volumes are summed up to calculate the amount of concrete poured in the region. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-052912 A Summary of the Invention [Problem to be solved by the invention]

[0004] Most design data used in construction is composed of BIM. However, at construction sites, it is difficult to operate BIM applications to manage construction. For this reason, it is difficult to edit design data using BIM applications to divide the work areas and pouring ranges of concrete at construction sites. Therefore, it has been difficult to efficiently manage the work areas and pouring ranges of concrete at construction sites using BIM. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of a work area management system, a work area management method, and a work area management program will be described with reference to Figs. 1 to 9. In this embodiment, the work area management system will be described as a work area management system that manages information about areas (work areas) divided as construction units in a construction project. For example, when pouring on-site concrete as part of construction work for building a building (structure), this work area management system is used to manage work areas that determine the range of concrete pouring for one time. In this case, the amount of concrete material required for pouring concrete in each work area is managed. In this embodiment, as shown in FIG. 1, the construction site management system uses a design terminal 10 and a management device 20 that are connected via a network.

[0009] (Hardware configuration description) 2, a hardware configuration of the information processing device H10 constituting the design terminal 10 and the management device 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 can also be realized by other hardware.

[0010] The communication device H11 is an interface that establishes a communication path with other devices and transmits and receives data, and is, for example, a network interface or a wireless interface.

[0011] The input device H12 is a device that accepts input of various information, such as a mouse, a keyboard, etc. The display device H13 is a display that displays various information, etc. In this embodiment, the input device H12 and the display device H13 function as an interface unit.

[0012] The storage device H14 stores data and various programs for executing various functions of the design terminal 10 and the management device 20. Examples of the storage device H14 include a ROM, a RAM, and a hard disk.

[0013] The processor H15 uses the programs and data stored in the storage device H14 to control each process in the design terminal 10 and the management device 20. Examples of the processor H15 include a CPU and an MPU. The processor H15 expands the programs stored in the ROM, etc., into the RAM and executes various processes for each process.

[0014] The processor H15 is not limited to a processor that performs software processing for all the 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:

[0015] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits that include combinations of these The processor includes a CPU and memory, such as RAM and ROM, that stores program codes or instructions configured to cause the CPU to execute processes. Memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0016] (System Configuration) Next, using Figure 1, we will explain each function of the construction site management system. The design terminal 10 is a computer terminal for designing a structure (three-dimensional CAD processing) using BIM (Building Information Modeling). In this embodiment, for example, "Autodesk Revit" (registered trademark) is used as the BIM application. In the BIM file (RVT file) generated by the BIM application, not only the shapes of elements (three-dimensional component data) used in construction but also the attributes (properties) of the building elements can be managed. The design terminal 10 includes a storage unit 11. The storage unit 11 stores a BIM file created by a BIM application.

[0017] The management device 20 is a computer system that manages information on building components. The management device 20 includes a control unit 21, a BIM information storage unit 22, a display information storage unit 23, an object information storage unit 24, a component management information storage unit 25, and a work area management information storage unit 26.

[0018] The control unit 21 manages three-dimensional models for managing information related to components, and manages construction using the components. For this purpose, the control unit 21 functions as a common management unit 211, a data editing unit 212, and a construction management unit 213 by executing management programs for executing each stage (a common management stage, a data editing stage, and a construction management stage).

[0019] The common management unit 211 realizes a Common Data Environment (CDE) by integrally managing data (such as 3D models) used in the construction of a building. For example, "Autodesk BIM360 Docs" (registered trademark) can be used for the common management unit 211. In this embodiment, as shown in FIG. 3, the common management unit 211 converts a BIM file (RVT format) into a display file (SVF format).

[0020] The data editing unit 212 edits (changes or adjusts) the BIM file. For the data editing unit 212, for example, "Autodesk Design Automation API for Revit" (registered trademark) can be used. In this embodiment, as shown in FIG. 3, the data editing unit 212 converts a BIM file (RVT format) into an object file (OBJ format) for each instance.

[0021] The construction management unit 213 manages the construction of materials used in building construction. The construction management unit 213 includes a viewer V1 equipped with an API for handling 3D models. For example, "Autodesk Forge" (registered trademark) can be used for this viewer V1.

[0022] As shown in Fig. 3, the viewer V1 incorporates a rendering function V11. For example, the rendering function V11 can use "Three.js." The viewer V1 runs on a graphics API such as WebGL to display the screen.

[0023] Here, a display file generated from a BIM file created by a BIM application is output by the viewer V1. Also, an object file generated from the BIM file is output by the viewer V1 via a rendering function V11.

[0024] Furthermore, the construction management unit 213 holds component information of a target for which an object file (OBJ format) is to be generated. In this embodiment, the target for application is a component constructed by pouring concrete at a construction site.

[0025] Furthermore, the construction management unit 213 holds win / lose condition information for determining a component type that has priority as a winning component type and a component type that has no priority as a losing component type when multiple elements interfere with each other in a three-dimensional space.

[0026] The BIM information storage unit 22 records BIM files (RVT format) created by a BIM application. This BIM file is recorded when a building is designed using 3D CAD. The BIM file includes a unique code, member type, element model, arrangement, and attributes for each member (element) in relation to the file code.

[0027] The file code information is an identifier for identifying a BIM file. The unique code information is an identifier for identifying the instances (elements) of components contained in this BIM file.

[0028] The component type information is information on the type of this component (such as "column", "beam", "window", etc.). The element model is a three-dimensional model (BIM model) of this component. The placement information is information regarding the coordinates (XYZ) at which each element model is placed. The attribute information is attribute information of this element (such as specifications, dimensions, weight, material, etc.) In this embodiment, the attribute information is used to identify the concrete member to be poured at the site.

[0029] A display file is recorded in the display information storage unit 23. For example, by using SVF (Streaming Vector Format) for this display file, instead of having individual instances, it is possible to reduce memory usage by sharing and referencing geometry of equivalent shapes, and to perform 3D display using a general-purpose application such as a browser. This display file is recorded when conversion from a BIM file to a display file is performed in the common management unit 211. The display file is configured to include a unique code, element model, arrangement, and attributes for each element (display model) for the file code.

[0030] The file code information is an identifier for identifying a display file. The unique code information is an identifier for identifying the elements (components) included in this display file. Here, the unique code of the elements included in the source BIM file is used.

[0031] The element model is a 3D model (display model) of this component. Here, the same 3D shape as the element included in the source BIM file is used. The placement information is information about the coordinates (XYZ) of where each element model is placed. Here, the coordinates of the elements included in the source BIM file are used.

[0032] The attribute information is the attribute information of this element (specifications, dimensions, weight, material, etc.). Here, the attribute information included in the source BIM file is used. In this embodiment, the attribute information is used to identify the concrete members to be poured at the site.

[0033] In the object information storage unit 24, an object file is recorded for each element to which the file is to be applied, in correspondence with the element model included in the display file. For example, this object file uses a file format (OBJ format) for recording shape data of an object used in three-dimensional computer graphics. In this OBJ format, the coordinates of vertices representing the shape of an element (model) in three-dimensional space, information on the faces constituting the object surface, parameters representing curves and curved surfaces, and the like are described in text format. This object file is recorded when the object file is generated from a BIM file in the data editing unit 212. In the object file, a file code, an element model as three-dimensional geometric information, and information on placement are recorded for each part (object model).

[0034] The file code information is an identifier for identifying an object file. The element model is a 3D model (object model) of this component. Here, the same 3D shape as the element contained in the original BIM file is used. This 3D shape makes it possible to calculate the area and volume of the region occupied by the element model. The placement information is information about the coordinates (XYZ) of where each element model is placed. Here, the coordinates of the elements included in the source BIM file are used.

[0035] Component management data is recorded in the component management information storage unit 25. This component management data is recorded when an object file is generated from a BIM file in the data editing unit 212. The component management data records information on a file code, unique code, component type, box coordinates, and process code for each component.

[0036] The file code information is an identifier for the object file. The unique code information is a unique code in the display file of the component converted into the object file. The object file and the element model in the display file are linked by the file code and the unique code recorded in the component management data.

[0037] The component type information is the type of this component. The box coordinate information is the coordinates (bounding box coordinates) that indicate the bounding box that this component exists in. Here, the minimum and maximum values ​​of the X axis, the minimum and maximum values ​​of the Y axis, and the minimum and maximum values ​​of the Z axis of the component are recorded. The process code information is an identifier for identifying the process in which the component is handled. This code can be used to identify the actual status of construction work, such as the planned construction date and the construction execution date.

[0038] The work area management information storage unit 26 records work area management data. This work area management data is recorded when the data editing unit 212 executes a work area division process for pouring concrete. The work area management data records information related to the area group name, base floor, and area coordinates. In addition, information related to the file code, unique code, and pouring quantity of the components included in the area coordinates is recorded.

[0039] The area group name records information regarding the name of the work section where one concrete pouring is performed. The foundation floor information records information that identifies the floor on which the concrete pouring will be performed.

[0040] The area coordinate information records information on the coordinates of the area of ​​the work area where the concrete will be poured. This area is specified by the vertices of a box space specified by its planar shape (corner shape) and height range. Note that a single area group may be composed of multiple box spaces combined. In this case, a common area group name is given.

[0041] The file code information and the unique code information are identifiers for identifying members (objects) that belong to an area group. The pouring quantity information is information about the capacity of the components belonging to the area group. By adding up the capacities of each component belonging to the area group, the total volume required for pouring concrete in this work area can be calculated.

[0042] (Model Management Processing) The model management process will be described with reference to FIG. First, the design terminal 10 executes a design process (step S11). Specifically, when designing a building, the designer starts a BIM application. In this case, the design terminal 10 outputs a CAD screen to the display device H13. The designer then designs the building by arranging three-dimensional models of each component (element) of each building on the CAD screen. In this case, the design terminal 10 sets attribute information (properties) of the building elements in each element model. When it detects that the design is complete, the design terminal 10 records a BIM file (RVT format) in the memory unit 11. For example, as shown in FIG. 5(a), a BIM model including a column model 501, a beam model 502, and a column model 503 is generated.

[0043] Next, the control unit 21 of the management device 20 executes a read process (step S21). Specifically, the person in charge acquires the BIM file (RVT format) recorded in the storage unit 11 of the design terminal 10 and inputs it to the management device 20. In this case, the common management unit 211 of the control unit 21 reads the BIM file and records it in the BIM information storage unit 22.

[0044] Next, the control unit 21 of the management device 20 executes a display conversion process (step S22). Specifically, the common management unit 211 of the control unit 21 converts the BIM file (RVT format) into a display file (SVF format). Then, the common management unit 211 records the converted display file in the display information storage unit 23.

[0045] 5(b), a pillar model 511, a beam model 512, and a pillar model 513 are generated by the display file. Here, the unique codes of the pillar model 511, the beam model 512, and the pillar model 513 are "Hashira01", "OhBari01", and "Hashira02", respectively.

[0046] Furthermore, the control unit 21 of the management device 20 executes a read process (step S23). Specifically, the data editing unit 212 of the control unit 21 reads the BIM file (RVT format).

[0047] Next, the control unit 21 of the management device 20 executes a process of extracting target components (step S24). Specifically, the data editing unit 212 of the control unit 21 acquires target component information from the construction management unit 213. Then, the data editing unit 212 identifies the target components by using the attributes of each element (instance) included in the BIM file.

[0048] Next, the control unit 21 of the management device 20 executes an object generation process (step S25). Specifically, the data editing unit 212 of the control unit 21 generates an object file for each identified element (instance). In this object file, the file code and unique code of the BIM file are recorded. Then, the data editing unit 212 records the generated object file in the object information storage unit 24.

[0049] 5(c), a column model 521, a beam model 522, and a column model 523 are generated by the object file. Here, the file codes of the column model 521, the beam model 522, and the column model 523 are "OBJ01", "OBJ02", and "OBJ03", respectively.

[0050] Next, the control unit 21 of the management device 20 executes a component management data generation process (step S26). Specifically, the construction management unit 213 of the control unit 21 generates component management data for the elements (instances) for which object files have been generated. The component management data includes the file code, unique code, and component type acquired from the BIM file for each element to which the data is applied. Furthermore, the construction management unit 213 identifies bounding box coordinates according to the arrangement of each element model, and records them in the component management data. Then, the construction management unit 213 records the generated component management data in the component management information storage unit 25.

[0051] In the component management data, the unique codes "Hashira01", "OhBari01", and "Hashira02" are recorded in association with the file codes "OBJ01", "OBJ02", and "OBJ03", respectively.

[0052] Next, the control unit 21 of the management device 20 executes an interference management process (step S27). Specifically, the construction management unit 213 of the control unit 21 uses the bounding box coordinates to extract elements that may interfere with each other. Next, the construction management unit 213 uses the win / lose condition information to remove the interfering parts of the element models of the losing member type by Boolean operations, and updates the object file in the object information storage unit 24. Furthermore, the construction management unit 213 updates the member management file with the bounding box coordinates from which the interfering parts have been removed.

[0053] Next, the control unit 21 of the management device 20 executes a display process (step S28). Specifically, the construction management unit 213 of the control unit 21 uses the viewer V1 to output the display model recorded in the display information storage unit 23 to the display device H13. Next, if an element model (object model) to be applied is recorded in the object information storage unit 24, the construction management unit 213 replaces the display model with the object model. As a result, the display model recorded in the display information storage unit 23 and the object model recorded in the object information storage unit 24 are displayed in a mixed manner.

[0054] Next, assume that a target component is divided. For example, assume that a component is divided into a plurality of work sections, or into areas in which concrete is poured in different processes.

[0055] In this case, the control unit 21 of the management device 20 executes the division process (step S31). Specifically, the construction engineer selects the element model (object model) output to the display device H13 and sets the division plane. For example, the construction management unit 213 of the control unit 21 divides the element model to generate two element models (object models). When the interference management process (step S27) is performed on the element model, the division process is performed on the object file from which the interference part has been removed. In this case, the construction management unit 213 generates an object file for each divided element model and records it in the object information storage unit 24. In this case, a branch code indicating the division is set to the unique code of the original object model. Furthermore, the shape and arrangement of the two divided element models are recorded in the object file. Next, the construction management unit 213 records the member management data for the divided element models in the member management information storage unit 25.

[0056] As shown in FIG. 5(d), it is assumed that the beam model 512 is divided at a cutting plane D1 on the display screen. Here, as shown in Fig. 5(e), beam models 522a and 522b are generated by dividing the beam model 522 by the object file. In this case, branch codes such as "OBJ02_DIV1" and "OBJ02_DIV2" are given as file codes of the beam models 522a and 522b.

[0057] In this case, in the material management data, the unique code "OhBari01" is recorded in association with the file codes "OBJ02_DIV1" and "OBJ02_DIV2."

[0058] Next, the control unit 21 of the management device 20 executes a division display process (step S32). Specifically, the construction management unit 213 displays the divided members using element models recorded in the object information storage unit 24. As shown in FIG. 5(f), the beam model 522 is displayed divided into beam models 522a and 522b.

[0059] (Work area management processing) The work section management process will be described with reference to Fig. 6. When dividing a work section in the work section management process, the person in charge inputs a work section division start command in the management device 20 using the input device H12.

[0060] In this case, the control unit 21 of the management device 20 executes a process for identifying the structure (step S41). Specifically, the construction management unit 213 outputs a target designation screen to the display device H13. This target designation screen includes a designation field for the structure to be the target of the work division. In this case, the person in charge identifies the file code of the desired BIM file in the BIM information storage unit 22.

[0061] Furthermore, the construction management unit 213 outputs the reference floor designation screen to the display device H13. Then, when the construction management unit 213 identifies the reference floor designated on the reference floor designation screen, it acquires the designated file code and the BIM file of the reference floor from the BIM information storage unit 22.

[0062] Next, the control unit 21 of the management device 20 executes a process of identifying a concrete member (step S42). Specifically, the construction management unit 213 identifies an element model of a concrete member by using the specified file code and the BIM file of the reference floor.

[0063] Next, the control unit 21 of the management device 20 executes a work area allocation setting process (step S43). Specifically, the construction management unit 213 outputs a work area allocation screen to the display device H13. In this case, the control unit 21 of the management device 20 executes a read process (step S21) to a display process (step S28). Furthermore, the construction management unit 213 outputs a floor plan including an element model of a concrete member at a reference floor to the display device H13.

[0064] In this case, as shown in Fig. 7, a floor plan of the standard floor of a structure 600 is output. This structure 600 includes columns 601, beams 602, and a grid line 603. The person in charge then uses the input device H12 to specify a desired work area range 610. Here, an area surrounded by a number of straight lines is specified as the work area range 610. Note that the work area range 610 may be specified by specifying the grid line and distance, and the area surrounded by straight lines parallel to the grid line may be specified.

[0065] Next, the height range of the work area range 610 is specified. In this case, a three-dimensional model 620 of the reference floor of the structure is output as shown in Fig. 8. Here, the height h1 of the work area range 610 is specified.

[0066] Next, the control unit 21 of the management device 20 executes a division process (step S44). Specifically, the construction management unit 213 divides each element model in the three-dimensional model 620 by the work area range 610. This process is performed by the division process (step S31) described above.

[0067] As shown in Fig. 7, beams 611 to 616 are divided by a work area range 610. In this case, as shown in Fig. 8, division planes 621 to 626 are set. Then, as shown in FIG. 9, the components 611a to 616a included in the work area 610 are identified.

[0068] Next, the control unit 21 of the management device 20 executes a group setting process (step S45). Specifically, when multiple work area ranges are set, the construction management unit 213 groups the multiple work area ranges into one work area range. In this case, the construction management unit 213 assigns a common area group name to the grouped work area ranges in the work area management information storage unit 26 and records them in association with each other.

[0069] Next, the control unit 21 of the management device 20 executes a capacity calculation process for each component (step S46). Specifically, the construction management unit 213 acquires the capacity of each element model included in the work area range. In this case, if the element model is divided, the capacity of the element model included in the work area range is calculated. Here, the construction management unit 213 calculates the volume of each divided element model using the object files of the components 611a to 616a in Fig. 9, and calculates the amount of concrete required for pouring concrete.

[0070] Next, the control unit 21 of the management device 20 executes a total volume calculation process (step S47). Specifically, the construction management unit 213 sums up the capacities of the acquired element models to calculate the total volume.

[0071] Next, the control unit 21 of the management device 20 executes a display process (step S48). Specifically, the construction management unit 213 outputs the calculated capacity of each component and the total capacity to the display device H13. Furthermore, when an element model desired by the person in charge is specified in the 3D model output to the display device H13, the capacity of the specified element model is output.

[0072] According to this embodiment, the following effects can be obtained. (1) In this embodiment, the control unit 21 of the management device 20 executes a display conversion process (step S22). This allows the 3D model to be displayed in 3D using a general-purpose application even if a BIM application is not installed on the terminal that displays the 3D model.

[0073] (2) In this embodiment, the control unit 21 of the management device 20 executes a process of extracting a target component (step S24), thereby making it possible to identify a component for which an object file needs to be generated.

[0074] (3) In this embodiment, the control unit 21 of the management device 20 executes an object generation process (step S25). This allows editing of the object (geometry operations such as division) that cannot be performed with the display model. Furthermore, by using the object file, the area and volume of the element model can be calculated.

[0075] (4) In this embodiment, the control unit 21 of the management device 20 executes a process for generating component management data (step S26). This allows the object file to be associated with the element model in the display file by the file code and unique code recorded in the component management data. Then, construction management can be performed using the attribute information of each component.

[0076] (5) In this embodiment, the control unit 21 of the management device 20 executes an interference management process (step S27), which allows adjustment even when interference occurs among a plurality of members.

[0077] (6) In this embodiment, the control unit 21 of the management device 20 executes a three-dimensional display process (step S28), which makes it possible to display a three-dimensional model of the building using the display file and the object file.

[0078] (7) In this embodiment, the control unit 21 of the management device 20 executes a division process (step S31). This allows editing such as division of members to be performed even on a terminal on which a BIM application is not installed.

[0086] 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.

[0087] In the above embodiment, the control unit 21 of the management device 20 executes a three-dimensional display process (step S28). Here, if an element model (object file) to be applied is recorded in the object information storage unit 24, the display model is replaced with the object model. Alternatively, only the edited member may be displayed based on the object file.

[0088] In the above embodiment, the control unit 21 of the management device 20 executes a process for identifying concrete members (step S42). The material used in the construction is not limited to concrete. For example, any material necessary for the construction of the work area may be used, and may be applied to materials such as reinforcing bars and fireproofing materials. For example, in the case of spraying fireproofing material, the components that require fireproofing material are identified, and the surface area of ​​the components included in the work area is calculated.

[0089] In the above embodiment, the control unit 21 of the management device 20 executes the work area allocation setting process (step S43). Here, the work area range is generated based on the planar shape and height. As long as the work area range can be specified in three dimensions, the method of specification is not limited to the method using the vertices and height of the planar shape. For example, the work area range may be specified using the three-dimensional coordinates of the vertices of the work area.

[0090] In the above embodiment, the control unit 21 of the management device 20 executes a division process (step S44). In this case, an object model generated from the BIM file by the model management process is used. If the members constituting the structure can be divided according to the construction area, the element model in the BIM file may be divided.

[0091] In the above embodiment, the control unit 21 of the management device 20 executes a display process (step S48). Here, the control unit 21 of the management device 20 may output warning information according to the size of the component. In this case, the control unit 21 records a threshold value for the size of the component, and outputs construction information based on the result of comparing the size of the component with the threshold value. For example, information regarding the range in which concrete can be poured and the appropriate range for the work area is used. Then, if the size of the component deviates from these ranges, warning information (for example, changing the display color of the component) is output.
