Description

[Technical field]

[0001] The present invention relates to building systems. [Background technology]

[0002] In buildings such as office buildings, commercial facilities, and apartment buildings, interior construction work is carried out after the framework is constructed. Interior construction work involves, for example, light steel construction (steel substructure assembly) to install ceiling and floor substructure materials to divide the space, and board construction (board installation) to attach gypsum board, which serves as the substructure for ceilings and wallpaper, to walls and ceilings.

[0003] In such interior construction work, materials such as standard boards and light steel frames are usually processed at the work site to fit the shape of the actual construction site (work site). For example, at the work site, workers measure the shape of the work site and, based on the measurement results, use tools such as sanders to perform processing such as cutting of the boards and light steel frames. However, processing such as cutting is dangerous and has the problem of generating sparks, which may pose a risk of fire, so it is desirable to reduce the amount of material processing work performed by workers at work sites.

[0004] Patent Document 1 discloses a technology that reduces the amount of material processing work done by workers at a work site. With this technology, the conditions at the work site where materials such as boards and lightweight steel frames are to be installed are measured in advance, and the measurement data is supplied to BIM to have BIM create data for processing the materials, so that the materials are pre-cut to fit the on-site dimensions before being delivered to the work site. This eliminates the need to process materials at the work site, which increases the safety of the work, and also shortens the work time because no processing work is required.

[0005] [Patent Document 1] Patent No. 679934 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned techniques are effective in terms of improving work safety and shortening work time, but do not fully consider the processing procedures at the actual work site when processing materials, etc.

[0007] In addition, depending on the construction site, the pre-cut materials delivered to the construction site may be similar in size and shape, which may lead to workers easily mistaking materials or taking time and effort to search for the materials.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The BIM system of this embodiment is a system that calculates the quantity of building materials and / or the shape of building materials suitable for a construction site in a building designed using BIM.

[0013] In this specification, BIM is an abbreviation for Building Information Modeling. This BIM information includes various information used in software that realizes general BIM. For example, in software that realizes BIM, it includes information on a three-dimensional model (3D model) of the structure that constitutes a building, that is, design information (e.g., dimensions of each part, etc.) required to create a 3D model. In addition to design information, it also includes various information (attribute information: for example, material, quantity, specifications, color, etc.) regarding each structure. In the BIM information, the information on the 3D model of the structure and the attribute information of the 3D model of the structure are associated with each other.

[0014] In this specification, the term "building" includes various structures such as wood, reinforced concrete, steel frame, steel-reinforced concrete, reinforced concrete, stone, and brick, but is not necessarily limited to these structures.

[0015] In this specification, the "parts" of a "building model" refer to the structural elements that make up a building, such as the walls, ceilings, and so on of the building.

[0016] In this specification, the term "structural elements constituting a building" includes structural elements constituting a building, such as pillars, walls, ceilings, and stairs.

[0017] In this specification, "building materials" includes structural materials such as reinforcing bars, concrete, and steel frames; base materials such as insulation materials, insulation spray and wrapping materials, structural plywood, and plasterboard (gypsum board); general wall and ceiling interior materials that make up wall and ceiling finishes, such as decorative calcium silicate boards, calcium silicate boards, rock wool sound-absorbing boards, and decorative gypsum boards; and general floor interior materials that make up floors, such as office automation floors, wooden floors, flooring materials, and tile carpets.

[0018] <Construction system 1 of this embodiment> As shown in Fig. 1, the construction system 1 of this embodiment includes a BIM system 10 that designs a building model, and a processing information calculation system 20 that calculates processing information for processing construction materials by using information on the building model M held by the BIM system 10. In the following, a typical case will be described in which the construction materials for which processing information is calculated in the construction system 1 of this embodiment are interior materials used for the interior of a building.

[0019] <BIMシステム10> The BIM system 10 includes a BIM information storage unit 11 and a building design unit 12.

[0020] The BIM information storage unit 11 stores BIM information that associates 3D model information of structures that constitute a building with attribute information of the 3D models of the structures. The BIM information storage unit 11 is capable of supplying the BIM information of each structure to the building design unit 12 based on a command from the building design unit 12.

[0021] The building design unit 12 uses the BIM information of the structures stored in the BIM information storage unit 11 to design a building model M, which is a 3D model of a building. For example, the building model M can be designed as a house or a building by laying out the columns and walls of the structures on a screen using the BIM information based on the command of a designer who designs the building model M. The building design unit 12 also has a function of storing the BIM information of the structures used in the designed building model M as information of the building model M in association with the layout information. The layout information is information including information on the relative positions of the structures constituting the building model M and information on the connection status of the structures. Therefore, the information of the building model M includes information on the shape and size (area and length) of each part formed by a plurality of structures and layout information of the structures constituting each part. For example, the information of the building model M includes information on the area of ​​the walls corresponding to the parts of the building model M, the distance between the ceiling and the floor that sandwich the wall (i.e., the height of the wall), the distance between the columns that sandwich the wall (i.e., the width of the wall), and the like.

[0022] It should be noted that a commercially available 3D CAD for designing buildings can be used for the BIM system 10. For example, Revit (registered trademark) or the like can be used.

[0023] <Processing information calculation system 20> The processing information calculation system 20 is a system for calculating the shape of a building material to be used at a construction site, and includes a material information storage unit 21, a site information storage unit 22, a construction specification information storage unit 23, and a processing information calculation unit 24. Specifically, the processing information calculation system 20 has a function in which the processing information calculation unit 24 calculates processing information for processing the building material to be applied at the construction site based on information acquired from the material information storage unit 21, the site information storage unit 22, and the construction specification information storage unit 23. For example, if the construction site is an inner wall, the processing information calculation unit 24 can calculate which building material (e.g., a base material, etc.) should be processed into what dimensions and what shape based on the shape of the construction site and the construction procedure based on that shape.

[0024] <Material information storage section 21> The material information storage unit 21 stores material information on interior materials, etc. used for each portion of the building model M. For example, if the interior materials, etc. are base materials, the shape of the base material, dimensional information of the base material (thickness, width, length, etc.), information on the material of the base material, etc. are stored as material information of the base material. This material information storage unit 21 is capable of supplying material information to the processing information calculation unit 24 based on a command from the processing information calculation unit 24.

[0025] <Site information storage section 22> The site information storage unit 22 stores site information including image information of the construction site where construction is actually performed and dimensional information of the construction site where construction is actually performed. Interior materials, etc. are installed at the site (construction site) after the foundation, framework, etc. of the building are formed, and information on the construction site in that state is included in the site information.

[0026] For example, an image of a construction site is included in the site information as image information. This image information includes the captured image itself and information such as the shape and dimensions of the construction site obtained by image processing of the captured image. Information such as the shape and dimensions of the construction site can be obtained by using a known image processing system. For example, information such as the shape and dimensions of the construction site can be obtained from the image by processing the captured image to detect an area in the construction site where interior materials, etc. are installed, and calculating the dimensions of the detected area based on the image.

[0027] In addition, when the dimensions and shape of the construction site are directly measured by the worker, the information on the shape and dimensions of the construction site obtained by direct measurement or scanning is included in the site information. The method of measuring the shape and dimensions of the construction site is not particularly limited. The shape and dimensions can be measured using various measuring devices such as a laser rangefinder, a laser scanner, a 3D scanner, and a scale.

[0028] In addition, it is desirable that the information on the shape and dimensions of the construction site obtained by image processing and the information on dimensions actually measured at the construction site contain information corresponding to the information on dimensions stored in the BIM information storage unit 11 of the BIM system 10. For example, in the case of installing an interior wall at a construction site, the BIM information storage unit 11 stores the distance between the ceiling and floor sandwiching the wall on which the interior wall is to be installed and the distance between the pillars sandwiching the wall, and in this case, it is desirable that the site information storage unit 22 contains the dimensions actually measured, such as the distance between the ceiling and floor sandwiching the wall on which the interior wall is to be installed and the distance between the pillars sandwiching the wall.

[0029] <Construction specification information storage unit 23> The construction specification information storage unit 23 stores construction procedure information, which is information on the construction procedure for applying building materials to a construction site. The construction procedure information also stores the shape of the building materials according to the construction procedure information in association with the construction procedure. When interior materials, etc. are applied to a construction site, the construction procedure differs depending on the shape of the construction site, for example, whether or not there is an opening, and the position and shape of the opening, and if the construction procedure differs, the shape of the interior materials, etc. to be applied also differs. Therefore, the construction procedure information includes, for each interior material, etc., information on the construction procedure according to the shape of the construction site and information on the shape of each interior material, etc. used in the construction procedure, and also includes information relating the two pieces of information.

[0030] <Processing information calculation unit 24> The processing information calculation unit 24 has a function of calculating processing information for processing interior materials, etc., to be installed at a construction site. In other words, the processing information calculation unit 24 has a function of calculating processing information including information necessary for processing interior materials, etc., into a shape that matches the shape of the construction site and the construction procedure. The information included in this processing information is not particularly limited. It is sufficient to include information necessary for the building materials to be installed at the construction site. For example, if the building material is a base material to be installed on a wall, the processing information includes its height and width, the inclination of the lower edge relative to the upper edge, and if an opening is formed in the wall, the shape and size of the notch formed in the base material corresponding to the opening, the position of the notch, etc. If the building material is a base material for a ceiling, the processing information includes the vertical and horizontal widths, the distance from the building frame to the ceiling, and if an opening is formed in the ceiling, the shape and size of the notch formed in the base material corresponding to the opening, the position of the notch, etc.

[0031] In this processing information calculation unit 24, processing information of interior materials, etc. is calculated by a processing information calculation process performed in the following steps (see FIG. 2). Note that information on which interior materials, etc. are to be installed at the construction site may be included in the site information stored in the site information storage unit 22, or an input unit, etc. for inputting the interior materials, etc. to be installed at the construction site may be provided in the processing information calculation system 20 and input from this input unit, etc.

[0032] <Processing information calculation procedure> First, the site information stored in the site information storage unit 22 is supplied to the processing information calculation unit 24. Then, the processing information calculation unit 24 executes a step of acquiring information on the construction site and the shape of the construction site from the site information. For example, if the construction site is a ceiling, the processing information calculation unit 24 acquires shape information on the construction site such as its area and the length of each side (distance between walls). If it is a wall, the processing information calculation unit 24 acquires information on its area, height (distance from floor to ceiling), width (distance between pillars), etc. In addition, if there are openings, allocations, accessories, etc., the processing information calculation unit 24 also acquires information on the positions, shapes, and sizes of the openings, allocations, accessories, etc.

[0033] When the processing information calculation unit 24 acquires the shape information of the construction location from the site information, the processing information calculation unit 24 executes a step of acquiring information on the shape and dimensions of the interior materials to be used at the construction location from the material information storage unit 21. For example, if it is a base material to be used for a wall or a board to be used for a ceiling, the processing information calculation unit 24 acquires information on the shape, thickness, width, length, etc. If it is a base material to be used for a wall, the processing information calculation unit 24 acquires information on the shape, thickness, width, length, etc. In addition, the processing information calculation unit 24 acquires construction procedure information corresponding to the shape information of the construction location from the construction specification information storage unit 23 based on the shape information of the construction location acquired from the site information, and acquires information on the shape of the building materials associated with the shape information of the construction location from the acquired construction procedure information.

[0034] Once this information is obtained, the processing information calculation unit 24 performs a step of comparing the shape of the construction site with the shapes of the interior materials, etc., using information on the shape of the construction site, information on the shape and dimensions of interior materials, etc., and information on the shape of building materials obtained in association with the shape information of the construction site, and calculating the shape of the interior materials, etc. that is suitable for the construction site.

[0035] <When installing from the center of the wall> For example, as shown in FIG. 3, the construction location is a wall W, and the wall W included in the shape information of the construction location is a horizontally long rectangle with a width of L1. The base material B included in the dimension information is a vertically long rectangle with a width of L2. In addition, the construction procedure is a case where the base material B is constructed from the center of the wall W toward the end. In this case, the processing information calculation unit 24 first calculates the shape of the base material B to be constructed in the center. For example, the processing information calculation unit 24 forms a state in which the base material B1 is installed in the center of the wall W. Specifically, the processing information calculation unit 24 forms a state in which the middle line BC of the base material B and the center line WC of the wall W coincide with each other. Then, the shapes of the base material B and the wall W are compared, and the shape in which the upper end edge of the base material B1 and the upper end edge of the wall W and the lower end edge of the base material B1 and the lower end edge of the wall W coincide with each other, and the shape of the base material B1 to be installed in the center of the wall W is stored as processing information. For example, the inclination angle of the upper and lower edges of the base material B1 with respect to the center line of the base material B1 and the length at the position of the center line of the base material B are stored as processing information. Next, with the base material B1 placed, the base materials B2 to B5 are placed on the left and right of the base material B1, respectively, and the shape of the wall W is compared with the shape of each base material B2 to B5. In other words, the base materials B2 to B5 are placed so that the side edges of the adjacent base materials B1 to B5 match each other, and the shape of the wall W is compared with the shape of each base material B2 to B5. Then, the processing information calculation unit 24 stores, as processing information, information required to process each base material B2 to B5 into a shape that matches the shape of the wall W. For example, similar to the base material B1, the inclination angle of the upper and lower edges of each base material B2 to B5 with respect to the center line and the length at the position of each center line are stored as processing information. In addition, when the base materials B4, B5 overlap with the side edges of the wall surface W, the shapes of the base materials B4, B5 are calculated so that the side edges match the side edges of the wall W, and the information necessary to process such base materials B4, B5 is stored as processing information.

[0036] <If there is an opening> For example, as shown in FIG. 4, the construction location is an open wall surface W2 with an opening Wh formed in the center. In addition, in the construction procedure, the base material B is constructed at the corner c of the opening Wh, and then the base material B is constructed at the other parts. In this case, the processing information calculation unit 24 first calculates the shapes of the base materials Be and Bd to be arranged near the opening Wh. The processing information calculation unit 24 forms a state in which the base material B is placed so as to include the corner c of the opening Wh. Specifically, the processing information calculation unit 24 forms a state in which the base materials B are arranged at the positions of the two corners c at the top of the opening Wh so that there is no gap between each of the base materials B (FIG. 4(A)). Then, the positions of the base material B, the open wall surface W2, and the opening Wh are compared, and the shape of the base material Be in which the upper edge coincides with the upper edge of the open wall surface W2 and the opening Wh, and a notch corresponding to the corner c of the opening Wh is formed is calculated, and information required for processing this base material Be is stored as processing information. Also, the shape of the base material Bd is calculated so that the side edge coincides with the side edge b of the opening Wh, and the bottom edge of the base material B1 coincides with the bottom edge of the opening wall W2, and information required to process this base material Bd is stored as processing information. Next, with the base materials Be and Bd placed at the position of the opening Wh, base materials B2 and B3 are placed on the left and right of the base materials Be and Bd, respectively, and the shape of the wall W2 is compared with the shape of each base material B2 and B3. That is, the base materials B6 to B9 are placed so that the side edges of the adjacent base materials Be, Bd, and B6 to B9 coincide with each other, and the shape of the opening wall W2 is compared with the shape of each base material B6 to B9. Then, the processing information calculation unit 24 calculates the shape of each base material B6 to B9 that matches the shape of the opening wall W2, and stores information required to process each base material B6 to B9 as processing information. In addition, when the base materials B6 to B9 overlap with the side edges of the wall surface W, the shapes of the base materials B6 to B9 are calculated so that the side edges coincide with the side edges of the wall W, and the information required to process such base materials B6 to B9 is stored as processing information.

[0037] In addition, as a procedure for constructing the base material B on the wall surface W2 with an opening, in addition to constructing the base material Be with a notch formed corresponding to the corner c of the opening Wh as shown in Fig. 4, there is also a construction method using only the base material B without a notch as shown in Fig. 5. In this case, as in the procedure shown in Fig. 4, the base materials B are arranged in the opening Wh part of the opening wall surface W2 so that there are no gaps between each base material B (Fig. 5(A)), and then the shape of the base materials Bf-Bg in contact with the opening Wh is calculated, and the information required to process the base materials Bf-Bg is stored as processing information. Next, from the state in which the base materials Bf-Bg are arranged at the position of the opening Wh, base materials B10 and B11 are arranged on the left and right of the base materials Bf and Bh, respectively, and the shape of the wall W2 is compared with the shape of each base material B10 and B11. That is, the base materials Bf, Bh, B10, and B11 are arranged so that the side edges of adjacent base materials Bf, Bh, B10, and B11 coincide with each other, and the shape of the opening wall surface W2 is compared with the shapes of the base materials B10 and B11. Then, the processing information calculation unit 24 calculates the shape of each base material B10 and B11 that matches the shape of the opening wall surface W2, and stores information required to process each base material B10 and B11 as processing information. In addition, when the base materials B10, B11 overlap with the side edges of the wall surface W, the shapes of the base materials B10, B11 are calculated so that the side edges match the side edges of the wall W, and the information necessary to process such base materials B10, B11 is stored as processing information.

[0038] <When forming a double-layered wall> For example, as shown in FIG. 6, assume that a double layer of base material B is to be installed on a wall surface W. In this case, the wall W included in the shape information of the construction site is a horizontally long rectangle with a height of H1. Also, the base material B included in the dimensional information is a vertically long rectangle with a height of H2 ( Next, the base material BG and intermediate material BF are placed in a layered state on the wall surface W with the base material B and intermediate material BS placed thereon. At this time, the base material BG is placed so as to hide the boundary between the base material B and intermediate material BS. In other words, the base material BG and intermediate material BF are placed so as to align the upper end edge of the base material BG with the upper end edge of the wall W. Then, in a state in which the base material BG and intermediate material BF are layered on the base material B and intermediate material BD, the shapes of the base material BG and intermediate material BF are compared with the shape of the wall W, the shape of the base material BG whose upper end edge coincides with the upper end edge of the wall W is calculated, and information required to process the base material BG is stored as processing information. Also, the shape of the intermediate material BF whose lower end edge coincides with the lower end edge of the wall W is calculated, and information required to process the intermediate material BF is stored as processing information. In addition, for the base material BG and intermediate material BF that overlap the side edge of the wall surface W, the shapes of the base material BG and intermediate material BF are calculated so that their side edges match the side edges of the wall W, and the information necessary to process such intermediate material BF and base material BG is stored as processing information.

[0039] ​As described above, in the construction system 1 of this embodiment, the processing information of construction materials such as interior materials is created by the processing information calculation system 20, so if site information on the construction site is created, the processing information for processing the construction materials according to the conditions of the construction site can be calculated by the processing information calculation system 20. Then, if the construction materials are processed in advance based on the processing information, the processing work at the construction site can be reduced.

[0040] Furthermore, since the building materials can be processed into a shape suited to the construction information of the construction site, processing work at the construction site becomes easier.

[0041] <Picking> Many of the building materials delivered to a construction site are similar in shape and size. In addition, multiple building materials are often delivered stacked together. Therefore, there is a possibility that a building material with a slightly different shape or size may be mistakenly selected and used instead of the building material that should be used.

[0042] Therefore, the processing information formed by the processing information calculation system 20 may include identification information regarding an identification label to be attached to the building material. Then, when the building material is processed based on the processing information, the identification label may be attached to the building material based on the identification information. By attaching such an identification label to the building material, it is possible to prevent the mix-up of building materials at the construction site, thereby reducing the labor of workers and shortening the construction time.

[0043] The identification label can be added according to a flow chart shown in FIG. 7, when creating the processing information, the processing information calculation unit 24 creates information (identification information) related to the identification label to be attached to the building material associated with the processing information as described above. Note that the identification information itself may be included as part of the processing information.

[0044] When the processing information is created, the processing information is transmitted from the processing information calculation unit 24 to a processing machine (for example, a panel cut saw, a panel saw, a cross-cut saw, a light iron base material cutting machine, etc.) that processes the building materials.

[0045] The processing machine processes the building materials into the specified dimensions and shape based on the processing information. When the processing is completed (or at the same time as the processing), the pre-cut function of the processing machine applies the identification label specified in the identification information to the building materials.

[0046] In addition, if the processing machine does not have the function of applying an identification label to the building material, after the processing by the processing machine is completed, an identification label is applied to the building material after the processing is completed (or during processing) by a device capable of applying a specified identification label to the building material. In this case, the identification information may be supplied to this device from the processing information calculation unit 24, or the identification information (i.e., the identification information received by the processing machine from the processing information calculation unit 24) may be supplied to this device from the processing machine.

[0047] <About identification labels> The identification label attached to the building material is not particularly limited as long as it allows a worker at the work site to recognize information about the building material. In other words, it is sufficient that the identification label allows a worker at the work site to recognize information about the dimensions of the building material, the construction location, etc.

[0048] As the identification label, for example, a label such as a QR code (registered trademark) or a barcode that can be read by a device to obtain information about the building material can be used. When using such an identification label, if a worker has a device that can read the identification label, the worker can grasp the information about the building material, and mix-up of the building materials can be prevented. In the case of a general QR code (registered trademark), if a worker installs an app that displays the information contained in the QR code (registered trademark) on a smartphone or tablet that the worker normally uses on-site, the worker can easily obtain the information about the building material.

[0049] When such an identification label is used, multiple pieces of information can be included in the identification label, such as shape information on the shape and dimensions of the building material, location information on the application site, and location information on the position where the building material is applied at the application site.

[0050] In particular, when shape information on the shape and dimensions of the building material, location information on the construction site, and location information on the location where the building material is to be constructed at the construction site are included, the device that reads the identification label may be provided with an image forming unit that forms a construction image in which the building material to which the identification label is attached (i.e., the building material whose attached identification label has been read) is placed at a predetermined location at the construction site based on the information included in the identification label. This allows the worker to understand the location where the building material will be constructed by checking the construction image, thereby improving the effect of preventing mix-ups of building materials.

[0051] <Classification by color> In addition, if the identification label attached to the building materials has multiple pieces of information, it can be more effective in preventing mix-ups, but it requires equipment to read the identification label. Furthermore, it takes time to understand the information about the building materials because the information about the building materials cannot be understood unless the identification label is read by equipment. Therefore, the identification label may simply be colored according to the classification of the building materials. If the identification label is simply colored, equipment to read the identification label is not required and the building materials can be quickly identified. For example, if the building materials are lightweight steel frames, multiple pieces of different lengths are brought in, but by applying a color according to the length as the identification label, it is possible to prevent workers from making a selection mistake. For example, the color coding according to the classification can be red for 1000 mm or less, blue for 1500 mm or more, and yellow for intermediate sizes. It is also possible to use red for 2000 mm or less, blue for 3000 mm or more, and yellow for intermediate sizes.

[0052] Furthermore, if the number of categories into which building materials are divided is too large, it becomes difficult for workers to understand which color corresponds to which category, so it is preferable to have 2 to 3 or 5 categories, or at most 7 or 8 categories.

[0053] <Work management department 60> At a construction site, multiple construction works such as interior construction, electrical equipment construction, fittings installation, wallpapering, painting, etc. are carried out by multiple workers (contractors) at each construction site, and each worker carries out the work simultaneously or in turn. Since workers are paid according to the status of each work, it is important to know the date and time when the work was carried out, the amount of work, and which worker carried out which work. The accuracy of such work status is ensured by the workers' reports and the construction manager's checks, but since multiple works are carried out by multiple workers, it is difficult to grasp the actual work status by confirming the status when all the work is completed at each construction site. For this reason, in order to accurately grasp the construction status, it is desirable to carry out the work of checking the work status as appropriate (preferably every day). However, the confirmation work requires work such as measuring the construction site, and in addition, it is difficult to quickly grasp the construction status and accurately by using methods based on numerical values ​​such as the construction area and construction amount, and it is also a heavy burden on workers and managers.

[0054] In order to reduce the burden on the workers and managers and ensure rapid and accurate understanding of the construction status, the construction system 1 of this embodiment is equipped with a work management unit 60 that manages information on the construction status at the construction site. The work management unit 60 has an estimate information storage unit 61 and a data creation unit 62 that has a function of creating work management data based on the information in the estimate information storage unit 61.

[0055] The estimation information storage unit 61 has a function of storing various information related to the construction status. The various information related to the construction status is, for example, completed work information including information on the place where the construction work was completed and the date and time when the construction work was completed at that place (which may include the date and time when the construction work was started), and worker information including information on the worker who performed the construction work. These pieces of information are input by an administrator using an input terminal or the like. The estimation information storage unit 61 stores the completed work information and the worker information in association with each other, and is configured to be able to obtain information on the worker who performed the work by specifying the content and date and time of the construction work. Of course, it is configured to be able to obtain information on which work was performed and when the work was started and completed from the worker information. The content of the construction work is, for example, the place where the work was performed, the construction materials applied, the area and the quantity of the construction materials applied, etc.

[0056] The data creation unit 62 has a function of acquiring completed work information and worker information from the estimation information storage unit 61 and creating work management data. This work management data is a list in which the contents of construction work, the date and time, and information on the worker are associated with each other. For example, the work management data is a table including the construction location, the work date, the worker, and the work content and amount of work (area, quantity, etc.) performed by the worker. Furthermore, if the purpose is to grasp the overall construction status of the construction site, the work management data may be composed only of the construction location, the work date, and the work content and amount of work (area, quantity, etc.) at the construction site (see FIG. 10(C)).

[0057] By providing such a work management unit 60, it becomes easier to manage the construction status, and it also becomes easier to manage payments to workers based on the work management data and to manage invoices to prime contractors, etc.

[0058] In particular, if the data creation unit 62 has a function of acquiring the building model M stored in the BIM information storage unit 11 and linking this building model M with the construction work and completed work information, the work content and the amount of work can be accurately grasped. For example, the data creation unit 62 is provided with a function of displaying the work content included in the completed work information, that is, the building materials and the amount of work, more specifically, the location where the building materials were constructed and the construction area and quantity, on the building model M. Then, if the displayed position and amount (area) of the building materials match with the building model M, it can be understood that the input of the work management data, that is, the work report and check, have been performed accurately, and if they do not match, it can be understood that there is an error in the input of the work management data. This can prevent errors in payment to workers and billing to prime contractors, etc.

[0059] If the work management unit 60 and the building model M are to be linked, it is desirable to input data to the estimation information storage unit 61 using an image based on the building model M. For example, an image (two-dimensional image or three-dimensional image) of the building model M of the construction site for which information is to be input is displayed on the display of the input terminal, and construction information for the building material, that is, the worker and the completion date of the work, can be input by selecting a building material on the image. Then, the display (color, etc.) of the building material for which input has been completed is changed so that the building material (construction site) for which construction has been completed can be recognized in the image of the building model M. Also, the input information is stored in the estimation information storage unit 61 in association with the building material of the building model M.

[0060] In this configuration, the progress of construction can be grasped as an image, making it easier to grasp the construction status. Moreover, since the building materials of the building model M and the construction information of the building materials are linked, the amount of work corresponding to the work content included in the completed work information can be accurately calculated in the work management data created by the data creation unit 62, so that payments to workers and billing to the prime contractor can be made accurately.

[0061] The following describes a flow for creating work management data when the data creation unit 62 of the work management unit 60 is linked to BIM information as described above.

[0062] First, when work is completed at the construction site, the worker who performed the work or the manager creates a construction site image (called a construction status image) in which marks are added to the areas where work has been done in the construction site image, which is a drawing of the construction site (this may be an image displayed on the screen of a tablet device or the like, or may be a printed matter). This mark is not particularly limited, but if it is a coloring of the worked area and building materials, it will be easy for the manager or other workers who sees the construction status image to understand the place where work was done and the building materials.

[0063] When the construction status image is created, information about the construction status is input to the work management unit 60 based on this construction status image. That is, the data inputter gives an instruction to the work management unit 60 to input construction information. At this time, the worker also specifies and inputs information about the construction site. When such input is performed, the data creation unit 62 acquires information about the architectural model M of the specified construction site from the BIM, creates an input screen on which predetermined information can be input into the construction site image based on the acquired architectural model M, and displays the screen on a monitor or the like.

[0064] When the input screen is displayed, the worker inputs information about the construction status based on the construction status image. Specifically, the worker specifies the location and construction materials marked in the construction status image, and inputs information such as the date and time of completion of the construction and the construction company. Then, when the input is completed, the data creation unit 62 forms and displays an image confirming the input information. Specifically, an image is formed and displayed in which the parts of the refining plant and construction materials where the work has been completed are colored. Then, if the inputter, such as a manager, checks the image and there are no problems, he or she instructs the end of input, and the data creation unit 62 creates work management data including the input information.

[0065] It should be noted that when using the above input method, a method may be adopted in which the worker directly inputs the work status from the input terminal and the manager checks the input. In this case, the worker himself can grasp the work status and check the entered contents by comparing them with the actual work site, which increases the accuracy of the information regarding the completion of construction. Of course, this also makes it easier for the manager to check and increases the accuracy of the check.

[0066] <Logistics Management Department 80> A construction site has many construction locations, and construction materials to be used at each location are transported to each construction location. For example, multiple construction materials are transported on pallets. Since multiple types of construction materials are used at each construction location, it is not possible to keep all of the construction materials used at each construction location, and it is necessary to transport appropriate construction materials to each construction location depending on the construction situation, etc.

[0067] Therefore, in order to properly transport construction materials to each construction site, it is desirable to provide a logistics management unit 80 having a construction status information storage unit 81 and a delivery decision unit 82 so that appropriate construction materials can be transported to each construction site depending on the construction status, etc.

[0068] The construction status information storage unit 81 has a function of storing construction status information, which is information on each construction carried out at each construction location on the building site. The construction status information stores, for example, information on the construction content that has been completed so far at each construction site, information on the content of construction currently being carried out (these may be collectively referred to as construction status information), and work process information, which is information on the order of construction at each construction site. In addition, the construction status information storage unit 81 has a function of updating the construction status information based on the input information when on-site construction information is input from an input terminal or the like.

[0069] In addition, when the construction system 1 of this embodiment has the above-mentioned work management unit 60, the construction status information storage unit 81 may acquire construction status information based on information from the work management unit 60 and update each piece of information, or the construction status information storage unit 81 may have only information regarding the order of construction at each construction site. However, since the information in the work management unit 60 is updated after the work of each work day or work for a certain period is completed, if the construction status information is to be used in real time, it is desirable for the construction status information storage unit 81 to have its own on-site construction information.

[0070] The delivery decision unit 82 has a function of determining the delivery timing of the building materials based on the work process information and the work status information stored in the work status information storage unit 81. Specifically, based on the work process information and the work status information in the work status information storage unit 81, the delivery decision unit 82 has a function of determining the delivery timing and the delivery location (work site, stock yard, etc.) of the building materials required at each work site, that is, the building materials to be delivered, based on the work process information and the work status information in the work status information storage unit 81. For example, it is assumed that information indicating that the work of installing the base material for the wall has been started at a certain work site A is input to the work process information in the work status information storage unit 81. Then, based on that information and the work status information, the delivery decision unit 82 has a function of determining the delivery timing and the delivery location (work site, stock yard, etc.) so that the delivery of the building materials required in the next process is completed to the work site A at the timing when the work of installing the base material is completed. The determined delivery timing and delivery location information are supplied to the terminal held by the worker, and the worker delivers the building materials to the specified location based on the information from the delivery decision unit 82.

[0071] By establishing such a logistics management department 80, it is possible to provide the construction site with the appropriate amount of construction materials at the appropriate time, thereby preventing problems such as a lack of necessary construction materials at the construction site, or problems such as more construction materials than necessary remaining at the construction site or in a stockyard, etc., resulting in reduced work efficiency. The flow of determining the delivery of construction materials by the logistics management department 80 will be described. As shown in Figure 9, when construction status information is input into the construction status information storage unit 81, the construction status information storage unit 81 updates the construction status information, and the delivery decision unit 82 creates delivery timing information including the delivery timing, delivery location, and building materials to be delivered based on the updated construction status information and work process information. When the delivery timing information is created, the delivery decision unit 82 transmits the created delivery timing information to the worker, and the worker delivers the specified building materials from the storage location to the specified work site based on that information. In this way, the timing for delivering the building materials is determined, so that the building materials can be delivered to the right place at the right time.

[0072] In addition, it is preferable that the logistics management unit 80 has a function of comparing the location of each construction site with the construction status information and the work process information to adjust the timing of delivery of the construction materials. For example, when the construction site A and the construction site B use the same work elevator, the work status of the construction site A is compared with the work status of the construction site B to determine the priority of which construction site the work elevator should be used to deliver the construction materials to. This allows the construction site to which the construction materials need to be delivered with priority, so that the efficiency of work can be improved not only at each construction site but also at multiple construction sites. In particular, when the number of work elevators that can carry large construction materials is limited, it is preferable that the logistics management unit 80 has a function of adjusting the timing and delivery route of delivery of the construction materials so that the construction materials delivered using the work elevator are limited or large construction materials are delivered with priority by the work elevator.

[0073] In addition, the construction status information storage unit 81 of the logistics management unit 80 may have a delivery status storage function that stores information about the location and time at which the building materials were delivered and delivery information input from the terminal held by the worker. In this case, the delivery decision unit 82 may be provided with a function to display a delivery management image created from the building model M and display the location of the building materials on the delivery management image based on the construction location image, information about the location and time at which the building materials were delivered, and delivery information. Then, the construction manager or the like can check the delivery management image to see if the delivery is being carried out properly, and if the worker can check the delivery management image on the terminal, etc., even if the delivery of the necessary building materials is delayed, the worker can know the location of the building materials and transport the building materials himself.

[0074] The logistics management unit 80 may also have a function of providing work process information, construction status information, and delivery information to the processing information calculation unit 24 of the processing information calculation system 20. In this case, processing information can be created for building materials to be delivered to an appropriate construction location at an appropriate time based on the work process information, construction status information, and delivery information. For example, at a construction site where construction work is delayed from schedule, even if processing information is created and building materials are processed, the processed building materials may not be transported to the construction location, and even if they are transported, they may remain stacked at the construction location until construction begins, which may interfere with other work. Also, when there is a delay in the delivery of building materials to be constructed first, the building materials may not be transported to the construction location, and they may remain stacked at the processing factory, which may interfere with other work. Therefore, if the logistics management unit 80 provides work process information, construction status information, and delivery information to the processing information calculation unit 24 of the processing information calculation system 20, the above problems can be prevented. In other words, when processing information for building materials to be used at a work site where construction is delayed is supplied, the processing can be put on hold, and if processing information supplied later than that information is for building materials to be provided to a work site that is in a position where work can be carried out by providing the building materials, priority can be given to the processing of the building materials supplied with that processing information.

[0075] <Explanation of Earthquake Resistant Structure Review System 70> As shown in FIG. 1, the construction system 1 of this embodiment may include a seismic structure review system 70 in addition to the BIM system 10 and the processing information calculation system 20 described above.

[0076] In places where seismic reinforcement is required, such as in the attic, under the floor, or in walls, it may be difficult for workers to directly measure dimensions or perform construction that meets the established standards. For example, in the attic of a suspended ceiling, there are various pipes and structures that support the suspended ceiling, and there is often no space to freely install seismic structural materials. In this case, it is necessary to select seismic structural materials that can demonstrate the desired seismic strength, and then select those that can actually be installed.

[0077] The earthquake-resistant structure examination system 70 has a function in which, based on information on the areas in the building model M to be earthquake-resistant reinforced and information on the earthquake-resistant structural materials stored in the earthquake-resistant structural material memory unit 71, the earthquake-resistant reinforcement model design unit 72 creates an earthquake-resistant reinforcement model in which earthquake-resistant structural materials are placed at the areas in the building model M to be earthquake-resistant reinforced.

[0078] Information on earthquake-resistant structural materials is stored in the earthquake-resistant structural material storage unit 71. The information on earthquake-resistant structural materials is, for example, information on the earthquake resistance strength, applicable locations, dimensions, and shapes of the earthquake-resistant structural materials, and this information can be used to form a 3D model of the earthquake-resistant structural material.

[0079] The seismic reinforcement model design unit 72 displays a 3D model of a part of a building for which seismic reinforcement is being considered, based on information about the building model M stored in the BIM system 10, and arranges and displays 3D models of seismic structural materials on this 3D model. In other words, the seismic reinforcement model design unit 72 has a function that allows an operator to input a part of a building for which seismic reinforcement is being considered, display a 3D model of that part, and allow the operator to select seismic structural materials and lay out the 3D model of the seismic structural materials on the 3D model of the part of the building. The seismic reinforcement model design unit 72 also has a function to form and store a seismic reinforcement model in which seismic structural materials are arranged.

[0080] As described above, in the earthquake-resistant structure examination system 70, a 3D model of an earthquake-resistant structural material can be placed on a 3D model of a portion of a building for which earthquake-resistant reinforcement is being considered. Then, even if various components (pipes, structural materials, etc.) exist in the portion for which earthquake-resistant reinforcement is being considered, the placement of the earthquake-resistant structural material can be considered so as not to interfere with these components. Therefore, earthquake-resistant reinforcement can be considered even in a portion where it is difficult for a worker to directly measure dimensions or perform construction that meets the established standards, such as inside a suspended ceiling or under the floor, and an appropriate earthquake-resistant reinforcement model can be designed.

[0081] In the above example, a case has been described in which equipment is already installed at the location in the building model M to be seismically reinforced. However, in the building model M, after arranging seismic structural materials so that appropriate seismic reinforcement can be performed, the location of the equipment may be determined. For example, the seismic reinforcement model design unit 72 is provided with a function for forming an equipment layout model in which equipment is arranged at a portion corresponding to the location in the building model to be seismically reinforced, based on the equipment information. Then, the seismic reinforcement model design unit 72 can design the equipment layout model after designing the seismic reinforcement model, and therefore it is possible to design a seismic reinforcement model in which seismic structural materials are arranged so that appropriate seismic reinforcement can be performed.
