Description

[Technical field]

[0001] The present invention relates to an estimation support system, an estimation support method, a storage medium, and an estimation support program, and more particularly to an estimation support system, an estimation support method, a storage medium, and an estimation support program that utilize CAD information and drawing information. [Background technology]

[0002] In order to realize a fair and appropriate unit price for public works, an estimation system has been established. This system specifies the type and standard of work, the type and standard of materials, and the type and standard of construction machinery in detail, systematically, and step-by-step, and also specifies the labor and expenses involved. Once the specifications of the work, such as the scale and type of work, are decided, a reasonable and appropriate amount is calculated. By using this estimation system, public works can be bid at a fair price. Calculations using this estimation system used to be done by hand or with spreadsheet software, but with the spread of PCs, estimation systems incorporating the estimation system have been developed and are now widespread. Civil engineering contractors use the estimation system to calculate the fair price for a work and submit bids.

[0003] For example, a conventional estimation system (see Patent Document 1) provides a construction estimation device that makes it very easy to select unit prices when selecting unit prices in order of priority. This estimation system (construction estimation device) has a unit price storage means that stores unit price data including construction element specific information and unit prices for each construction element for each unit price type, a unit price link storage means that stores the correspondence between unit price data of different unit price types for corresponding construction elements, a unit price display means that extracts and displays construction element specific information and unit prices corresponding to the extraction target specific information from the unit price data of the specified unit price type, and a price calculation means that calculates the price based on the selected unit price and the input quantity, and for construction elements for which a unit price corresponding to the extraction target specific information does not exist in the unit price data of the specified unit price type, the unit price display means searches for the unit price data of a unit price type with a lower priority and which has a unit price corresponding to the extraction target specific information, and extracts and displays the unit price.

[0004] [Patent Document 1] JP 2011-227754 A Summary of the Invention [Problem to be solved by the invention]

[0005] This conventional estimating system supports the user's selection operation by displaying candidate unit prices to make it easier to select unit prices after the user has selected the construction elements. However, although this conventional system can support the selection of unit prices, it cannot automatically select the initial construction elements. In other words, the challenge for estimating systems is to automate the selection of construction elements, but such a system has not been proposed or developed. On the other hand, CAD systems are widespread in civil engineering works, and there are CAD objects and graphic elements that contain important data for construction elements, but no techniques have been developed to utilize these in estimating systems.

[0006] Therefore, an object of the present invention is to provide an estimation support system, an estimation support method, a storage medium, and an estimation support program that acquire information from a CAD system or drawings and generate construction identification information based on the information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0033] 1 is a block diagram showing an outline of an estimation support system according to an embodiment of the present invention. As shown in the figure, the estimation support system 100 (ASS) has a control unit (CPU, processor) CON, an input unit IN, an output unit OUT, a communication unit COM, a memory unit MEM, and a display unit DIS.

[0034] The memory unit MEM stores a graphic construction link table FCL including graphic elements and construction identification information associated with the graphic elements. The control unit CON includes an acquisition unit ACQ, an analysis and extraction unit ANA, a generation unit GEN, an AI engine AIE, and an AI storage processing unit AIM.

[0035] The acquisition unit ACQ acquires drawing information including graphic elements. The analysis and extraction unit ANA analyzes the acquired drawing information and extracts graphic elements including closed areas. The generation unit GEN generates construction identification information corresponding to the extracted graphic elements (shape, position, coordinates, placement in the entire drawing, the relevant graphic in the configuration and position of other elements, etc.) by referring to the graphic construction link table FCL.

[0036] The output unit OUT can output the information stored in the server and the generated information to the printer PRN1. The display unit DIS can also display the information stored in the server and the generated information. The input unit IN accepts operation instructions and information input from the outside via the mouse MUS, the keyboard KBD, or the communication unit COM. It should be noted that the generated information, intermediate data, and acquired data can be transmitted to the outside, displayed on the display unit, and the generated information, intermediate data, and acquired data can be stored in the storage unit in the other embodiments described below. It is preferable that the system (apparatus) is constructed on a computer such as a general-purpose computer, a specific-purpose computer, a server, or a PC, or that the system is realized (executed) by a program module in the CPU or storage unit of the computer, or by reading the program module from an external server or storage, and this is also true in each of the following embodiments.

[0037] FIG. 2 is a flow chart showing an example of processing executed by the cost estimation support system shown in FIG. 1. As shown in the figure, in step S11, a graphic construction link table including graphic elements and construction identification information associated with the graphic elements is stored. Next, in step S12, drawing information including the graphic elements is acquired. Then, in step S13, the acquired drawing information is analyzed to extract graphic elements including closed regions. Finally, in step S14, based on the extracted graphic elements, the graphic construction link table is referenced to generate construction identification information corresponding to the graphic elements. The generated construction identification information is transmitted to the cost estimation system ACC via the communication unit COM and used to generate cost estimation data. The step of storing the graphic construction link table may be performed in advance, or may be omitted after being performed once.

[0038] FIG. 3 is a cross-sectional view of road construction processed by the cost estimation support system shown in FIG. 1. As shown in the figure, cross-sectional view ZK10 is a cross-sectional view of the layers formed by road construction. Embankment x1b is placed on the ground x1a, and slope reinforcement concrete x2a, x2b is formed on the slope of the embankment. Then, the road body x3a, roadbed x3b, lower roadbed x4a, upper roadbed x4b, and surface layer x4c are formed on the embankment x1b.

[0039] The scale display CC10 shows 1 / 10000. The cross-sectional view ZK10, which is a type of plan view, is acquired by the acquisition unit ACQ, and the analysis and extraction unit ANA recognizes closed areas and extracts "graphical elements" that include at least one closed area. Here, as an example, slope reinforcement concrete x2a, x2b, embankment x1b, road body x3a, and roadbed x3b are extracted as graphic elements.

[0040] Fig. 4 is a schematic diagram showing how a cross-sectional view of a road construction project is processed by the cost estimation support system shown in Fig. 1. As shown in the figure, the graphic construction link table FCL associates slope reinforcement concrete NRC with slope reinforcement construction identification information NMNH01.

[0041] Slope reinforcement concrete NRC is a drawing element of slope reinforcement concrete in general slope reinforcement work, and includes information on its shape, size, cross-sectional or plan view, and preferably information on its location (coordinate information) in the drawing, information on adjacently placed graphic elements, information on graphic elements placed on the same drawing, etc. The slope reinforcement work identification information NMNH01 may be character information, or may be a unit code used in an estimation system.

[0042] In this example, based on the extracted slope reinforcement concrete x2a, the graphic work link table FCL is referenced, and slope reinforcement concrete NRC, which is similar to the shape of the slope reinforcement concrete x2a from the shape of the graphic element, is hit, and the slope reinforcement work identification information NMNH01 associated with it is hit. That is, the slope reinforcement work identification information NMNH01 associated with the hit slope reinforcement concrete NRC is generated. Then, the slope reinforcement work identification information NMNH01 is transferred to the cost estimation system ACS, and the cost estimation process FLE2 generates cost estimation information FLE2a for the slope reinforcement work by manually inputting the slope reinforcement work identification information NMNH01 and the quantity of this slope work by FLE2a.

[0043] FIG. 5 is a flow chart showing an example of processing executed in the estimation support system shown in FIG. 1. As shown in the figure, in step S21, a graphic construction link table including graphic elements and / or attached information related to the graphic elements and construction identification information associated with the attached information and / or the graphic elements is stored. Next, in step S22, drawing information including the graphic elements is acquired, and a document file (such as Word), a spreadsheet file (such as Excel), a PDF file, a CAD file, or a CAD-related file associated with the drawing information is further acquired. Then, in step S23, the acquired drawing information is analyzed, graphic elements including closed regions are extracted, and attached information related to the extracted graphic elements is further extracted from the document file (such as Word), the spreadsheet file (such as Excel), the PDF file, the CAD file, or the CAD-related file.

[0044] Finally, in step S24, the graphic construction link table is referenced based on the extracted auxiliary information and the graphic information to generate construction identification information corresponding to the graphic element and / or the auxiliary information. Note that once the storage step such as step S21 is performed, it is not necessary to perform it again until the information is changed. Alternatively, the storage step becomes unnecessary by installing a ROM or flash memory storing the information in the device or computer.

[0045] FIG. 6 is another cross-sectional view of the road construction processed by the cost estimation support system shown in FIG. 1. As shown in the figure, the cross-sectional view ZK11 is a cross-sectional view of the layers formed by the road construction. The embankment x1b is placed on the ground x1a, and slope reinforcement concrete x2a, x2b is formed on the slope of the embankment. Then, the road body x3a, the roadbed x3b, the lower roadbed x4a, the upper roadbed x4b, and the surface layer x4c are formed on the embankment x1b. The scale display CC11 shows 1 / 10000. The scale display CC11 also includes the construction ID number CID002 for identifying the construction.

[0046] In this example, the attached information related to the graphic elements and drawings includes a document folder DOCF containing multiple document files, a spreadsheet file folder CALF containing multiple spreadsheet files, and a PDF folder PDFF containing multiple PDF files. In this example, the attached information is associated with the drawings (graphic elements) by a construction ID number. That is, the construction ID number CID002 of the cross-sectional view ZK11 is associated with the attached information having the same construction ID number CID002.

[0047] The cross-sectional view ZK11, which is a type of plan view, and the files, document folder DOCF, spreadsheet file folder CALF, and PDF folder PDFF, which are candidates for attached information, are acquired by the acquisition unit ACQ, and the analysis and extraction unit ANA recognizes closed areas and extracts "graphical elements" that include at least one closed area. Here, as an example, slope reinforcement concrete x2a and x2b, embankment x1b, road body x3a, and roadbed x3b are extracted as graphic elements. In addition, the construction ID number CID002 of the cross-sectional view ZK11 and the attached information with the same construction ID number CID002 are acquired and extracted.

[0048] FIG. 7 is a schematic diagram showing how the sectional view of the road construction is processed by the cost estimation support system shown in FIG. 1. As shown in the figure, in this example, in addition to the graphic elements, additional information related to the graphic elements is used. By using the additional information, it is possible to generate construction identification information with higher accuracy and to generate quantities with higher accuracy. As shown in the figure, in this example, the construction ID number CID002 of the cross-sectional view ZK11 and additional information having the same construction ID number CID002 are obtained. Then, four items related to the graphic element slope reinforcement concrete x2a in this figure are extracted. The additional information of the slope reinforcement concrete includes the slope construction method AM002, the standard NM005 of the slope reinforcement concrete, the quantity Xm3 (cubic m) of the slope reinforcement concrete, and the dimensions of the slope reinforcement concrete, such as the area, length, width, and thickness. It is preferable to associate these additional information with the graphic elements and store them in the graphic construction link table, but it is also preferable to use them in searches.

[0049] Fig. 8 is a schematic diagram showing a mechanism for associating ancillary information with construction identification information. As shown in the figure, no ancillary information is initially associated with the graphic construction link table FCL. Then, some ancillary information for slope reinforcement concrete is extracted, as shown in Fig. 7. This system associates this ancillary information with the slope reinforcement construction NMHK01 and stores it as the graphic construction link table FCL10.

[0050] FIG. 9 is a schematic diagram showing how the cost estimation support system shown in FIG. 1 processes a cross-sectional view of a road construction project. In this example, a mechanism is provided for estimating the quantity of components using scale information and generating that quantity. As shown in the figure, the scale display CC11 shows 1 / 10000. The scale display CC11 also contains the construction ID number CID002 for identifying the construction project. Here, the scale information and the size of the graphic element are extracted from the acquired drawing information. As an example, slope reinforcement concrete x2a is used. From this graphic element, the actual volume and quantity of the slope reinforcement concrete, "250m3", is calculated from the size on the drawing (length, width, height), the scale information of 1 / 10000, and the expected thickness.

[0051] Then, slope reinforcement work identification information NMNH01 (unit-hour code) associated with the hit slope reinforcement concrete NRC is generated. Then, the slope reinforcement work identification information NMNH01 is transferred to the estimation system ACS, and the estimation process FLE3 generates the estimation information FLE3b of the slope reinforcement work from the slope reinforcement work identification information NMNH01 and the quantity of this slope work, 250 m3. In this way, by utilizing the scale information to estimate the quantity, it becomes possible to generate the estimation information without manual input.

[0052] FIG. 10 is a flowchart showing an example of processing executed by the estimation support system shown in FIG. 1. This is a configuration using an AI engine. As shown in the figure, in step S31, the AI ​​engine is made to learn pairs of geometric elements included in drawing information and construction identification information corresponding to the geometric elements as teacher data. This is done by someone familiar with estimation systems and drawings specifying pairs of geometric elements and construction identification information corresponding to the geometric elements as correct answer data (teaching data) and making the AI ​​engine learn by machine learning. In this step, a certain amount of teaching data is made to learn.

[0053] Next, in step S32, the AI ​​storage processing unit uses the AI ​​engine to store a large amount of drawing information including graphic elements and construction identification information corresponding to the drawing information in the storage unit as a graphic construction link table including the graphic elements and the construction identification information associated with the graphic elements. Next, in step S33, the drawing information including the graphic elements is acquired. Then, in step S34, the AI ​​engine is used to analyze the acquired drawing information and extract graphic elements including closed areas. Finally, in step S35, based on the extracted graphic elements, the graphic construction link table is referenced to generate construction identification information corresponding to the graphic elements.

[0054] FIG. 11 is a schematic diagram showing a method for making an AI engine learn pairs of geometric elements included in drawing information and construction identification information corresponding to the geometric elements as teacher data. A person familiar with estimating systems and architectural and civil engineering drawings specifies pairs of geometric elements and construction identification information corresponding to the geometric elements as correct answer data (teaching data), and makes the AI ​​engine learn by machine learning. As shown in the figure, there is estimation information ACI, which contains: "Cutting and earthwork BK001, quantity xxm3", "Slope reinforcement work BK005, quantity yym3", "Road construction BK007, quantity zzm2" "Road construction BK0015, quantity ddm2" is stored.

[0055] And there is drawing information OB22 corresponding to these estimation information, and there are graphic elements such as slope reinforcement concrete y2, slope y1a, roadbed y3c, road body y3b, and ground y3a. Someone who is familiar with the estimation system and architectural and civil engineering drawings associates the identification codes of the graphic elements with the estimation information as follows. Cutting and earthwork BK001, quantity xxm3 y1a, y1b Slope reinforcement work BK005, quantity yym3 y2 Road construction BK005, quantity yym3 y3a, y3b, y3c Road construction BK005, quantity yym3 y4a, y4b, y4c This is the graphic element associated cost estimation information ACI-d. In this way, multiple graphic elements may be associated with one construction work identification information (and quantity information). In other words, one construction work may involve the formation of several layers or components, or may include multiple processes. In such cases, multiple graphic elements are associated with one construction work identification information.

[0056] Fig. 12 is a schematic diagram showing a method for creating items in a graphic construction link table while having an AI engine learn pairs of graphic elements included in drawing information and construction identification information corresponding to the graphic elements as training data. Fig. 11 shows a method for creating training data for an AI engine to learn, but Fig. 12 explains a technique for using this training data to have an AI engine learn and create a table.

[0057] As described in FIG. 11, in FIG. 12, the graphic element association integration information ACI-d associates integration information with identification codes of graphic elements as follows. Cutting and earthwork BK001, quantity xxm3 y1a, y1b Slope reinforcement work BK005, quantity yym3 y2 Road construction BK005, quantity yym3 y3a, y3b, y3c Road construction BK005, quantity yym3 y4a, y4b, y4c This geometric element association estimation information ACI-d is used as training data to train the AI ​​engine of this system. The trained AI engine AIE-s is created. This system directly uses this trained AI engine AIE-s to analyze the acquired drawing information, extract geometric elements that include closed areas, and based on the extracted geometric elements, the trained AI engine AIE-s can generate construction identification information corresponding to the geometric elements. Here, we will explain the technique for constructing a geometric construction link table.

[0058] As shown in the figure, it is preferable to generate the graphic construction link table FCL2 from the trained AI engine AIE-s. In this example, since quantity information is also included as an item, there is no need for the user to input the quantity, extract the quantity from the additional information, or have the user guess the quantity.

[0059] FIG. 13 is a schematic diagram showing a technique for finding associations (unknown associations) between geometric elements that cannot be associated and cost estimation information (construction identification information) using a trained AI engine, advancing the AI ​​engine's learning, and constructing a geometric construction link table. The trained AI engine AIE-s has learned in advance what geometric elements in what drawing information should be associated with what construction identification information in what cost estimation information. Therefore, if the trained AI engine AIE-s is made to read unknown cost estimation information and the corresponding unknown drawing information (including geometric elements), it is possible to find associations (i.e., correspondences) between each construction identification information and each geometric element, further perform these association processes, and further incorporate them as teacher data. In other words, the AI ​​engine is able to understand associations between cost estimation information and geometric elements that only experienced engineers can understand, and make these associations.

[0060] For example, as shown in the figure, the estimation information CIAA including the construction identification information and quantity information should correspond and be associated with the graphic element A111. This association and correspondence is, of course, unknown to this system. The trained AI engine AIE-s has previously learned the association between the same or similar thing as the estimation information CIAA and the same or similar thing as the graphic element A111, so it determines that the estimation information CIAA (construction identification information and quantity) corresponds to and should be associated with the graphic element A111, and stores the correspondence and association inside itself, as in the trained engine AIE-s2, and makes it learned. Then, the trained engine AIE-s2 can send the correspondence and association to the outside and construct and configure it as the correspondence and association item AC111 of the graphic construction link table FCL3.

[0061] Fig. 14 is a block diagram showing an outline of a cost estimation support system according to one embodiment of the present invention (CAD object compatible version). In this embodiment, the target is a CAD object, not a floor plan. Although a planar CAD object (i.e., a two-dimensional CAD object) may also be used, the following description will be mainly directed to a three-dimensional CAD object.

[0062] As shown in the figure, the estimation support system 200 (ASS) has a control unit (CPU, processor) CON, an input unit IN, an output unit OUT, a communication unit COM, a memory unit MEM, and a display unit DIS. Note that elements and functions not specifically described in Fig. 13 are similar to those in Fig. 1, and description thereof may be omitted.

[0063] The memory unit MEM stores a graphic construction link table 3DFCL including graphic elements and construction identification information associated with the graphic elements. The control unit CON includes an acquisition unit ACQ, an analysis and extraction unit ANA, a generation unit GEN, an AI engine AIE, and an AI storage processing unit AIM.

[0064] The acquisition unit ACQ acquires drawing information (here, CAD files, CAD information, or CAD object groups) including graphic elements. The analysis and extraction unit ANA analyzes the acquired drawing information and extracts graphic elements including closed areas. The generation unit GEN generates construction identification information corresponding to the extracted graphic elements (shape, position, coordinates, placement in the entire drawing, the graphic in the configuration and position of other elements, etc.) by referring to the graphic construction link table FCL.

[0065] The output unit OUT can output the information stored in the server and the generated information to the printer PRN1. The display unit DIS can also display the information stored in the server and the generated information. The input unit IN accepts operation instructions and information input from the outside via the mouse MUS, the keyboard KBD, or the communication unit COM. It should be noted that the generated information, intermediate data, and acquired data can be transmitted to the outside, displayed on the display unit, and the generated information, intermediate data, and acquired data can be stored in the storage unit in the other embodiments described below. It is preferable that the system (apparatus) is constructed on a computer such as a general-purpose computer, a specific-purpose computer, a server, or a PC, or that the system is realized (executed) by a program module in the CPU or storage unit of the computer, or by reading the program module from an external server or storage, and this is also true in each of the following embodiments.

[0066] FIG. 15 is a flow chart showing an example of processing executed in the estimation support system shown in FIG. 14. As shown in the figure, in step S41, the storage unit stores a graphic construction link table including CAD objects and construction identification information associated with the CAD objects. Next, in step S42, the acquisition unit acquires CAD information including the CAD objects. Then, in step S43, the analysis and extraction unit analyzes the acquired CAD information and extracts at least one CAD object. Finally, in step S44, the generation unit generates construction identification information corresponding to the CAD object based on the extracted CAD object by referring to the graphic construction link table. The generated construction identification information is transmitted to the estimation system ACC via the communication unit COM and used to generate estimation data. The storage step of storing the graphic construction link table may be performed in advance, or may be omitted after being performed once.

[0067] It is also preferable that the analysis and extraction unit ANA further extracts scale information and a size of the CAD object, and that the generation unit GEN further generates a construction quantity of the construction corresponding to the construction identification information based on the scale information and the size.

[0068] FIG. 16 is a schematic diagram (extraction stage) of CAD information processed by the cost estimation support system shown in FIG. 14. As shown in the figure, the acquisition unit acquires CAD information CADIN. The CAD information CADIN includes CAD object n1, CAD object m2, CAD object m3, and CAD object m4. In reality, complex dams, bridges, roads, and multi-level intersections are acquired as CAD information, but for the sake of convenience in drawing and explanation, simplified CAD information will be used for the explanation. The analysis and extraction unit analyzes the acquired CAD information CADIN and extracts CAD object n1, CAD object m2, CAD object m3, and CAD object m4.

[0069] FIG. 17 is a schematic diagram (generation stage) of CAD information processed by the cost estimation support system shown in FIG. 14. As shown in the figure, the processing of CAD object n1 extracted by the analysis and extraction unit will be described. The generation unit refers to the graphic construction link table 3DFCL based on the CAD object n1. In the graphic construction link table 3DFCL, a cylindrical CAD object ET10 is associated with N1 construction (N10009). Similarly, a CAD object of a rectangular prism with a hollow center is associated with N5 construction (N54004), and the rectangular prism CAD object is associated with SSS construction (SS001).

[0070] In this embodiment, the CAD object ET10 is hit by referring to the graphic construction link table 3DFCL based on the CAD object n1, and the N1 construction (N10009) associated with it is hit. That is, the generation unit generates construction identification information N1 construction (unit code: N10009). This system transmits the generated construction identification information to the estimation system ACS. The estimation system ACS receives the construction identification information N1 construction (unit code: N10009) and accepts manual input FLE2a of the quantity of this construction. As the estimation system, once the target construction N1 construction and its quantity are determined, estimation information for the N1 construction is generated (generation step FLE3b).

[0071] FIG. 18 is a schematic diagram (generation stage) of CAD information processed by the cost estimation support system shown in FIG. 14. In this embodiment, all CAD objects included in the CAD information are processed. The acquisition unit acquires CAD information CADIN. The CAD information CADIN includes CAD object n1, CAD object m2, CAD object m3, and CAD object m4. The analysis and extraction unit analyzes the acquired CAD information CADIN and extracts CAD object n1, CAD object m2, CAD object m3, and CAD object m4. Then, based on each CAD object, construction identification information corresponding to each CAD object is generated by referring to the graphic construction link table 3DFCL.

[0072] That is, N1 construction (unit code N1009) is generated from CAD object n1, M2 construction (unit code M2009) is generated from CAD object m2, M3 construction (unit code M3009) is generated from CAD object m3, and M4 construction (unit code M4009) is generated from CAD object m4 (generation step FLEW22). The generated construction identification information is then sent to the cost estimating system ACS, where each construction identification information and the corresponding quantities are manually entered, and finally, cost estimating information for construction corresponding to all objects in the CAD information is generated.

[0073] FIG. 19 is a schematic diagram showing a method of making an AI engine learn a pair of a CAD object included in CAD information and estimation information (construction identification information) corresponding to the CAD object as teacher data. A person familiar with estimation systems and architectural and civil engineering drawings specifies a pair of a CAD object and estimation information (preferably construction identification information) corresponding to the CAD object as correct answer data (teaching data), and makes the AI ​​engine learn machine learning. In this embodiment, the estimation information itself is described as being associated with a CAD object. What is important in the present invention is the association between the estimation information and the CAD object. Using this association, estimation information is generated from the CAD object. Until now, the association between the estimation information and the CAD object has been realized as an item in the figure construction link table, but as shown in this figure, it is also possible to include the CAD object itself or information connecting to the CAD object as an item in the estimation information.

[0074] As shown in the figure, the cost estimation information ACI includes the cost estimation information item Z1C for the work Z1, the cost estimation information item Z2C for the work Z2, and the cost estimation information item Z3C for the work Z3. The CAD information CADIN includes the CAD object Oz1, the CAD object Oz2, and the CAD object Oz3. In order to associate the cost estimation information items with the CAD objects, the CAD objects are incorporated into the cost estimation information and associated. As shown in the cost estimation information ACI-d2 in the figure, the CAD object Oz1 is associated with the cost estimation information item Z1C for the work Z1. The CAD object Oz2 is associated with the cost estimation information item Z2C for the work Z2. The CAD object Oz3 is associated with the cost estimation information item Z3C for the work Z3. The AI ​​engine learns such associations.

[0075] The present invention can also be realized in a form in which such associated items are stored in one file. For example, the following is the case. An estimation support system, comprising: A storage unit that stores CAD objects and cost estimation information including construction identification information associated with the CAD objects; an acquisition unit for acquiring CAD information including a CAD object; an analysis and extraction unit that analyzes the acquired CAD information and extracts at least one CAD object; A generation unit that generates construction identification information corresponding to the extracted CAD object by referring to the estimation information based on the extracted CAD object; An estimation support system having the above.

[0076] An estimation support system, comprising: A storage unit that stores estimation information including a graphic element and construction identification information associated with the graphic element; An acquisition unit for acquiring drawing information including graphic elements; an analysis and extraction unit that analyzes the acquired drawing information and extracts geometric elements including closed regions; A generating unit that generates construction identification information corresponding to the extracted graphic elements (shape, position, coordinates, arrangement in the entire drawing, the graphic elements in the configuration and position of other elements, etc.) by referring to the estimation information; An estimation support system having the above.

[0077] An estimation support system, comprising: A storage unit that stores CAD information including a CAD object and construction identification information associated with the CAD object; an acquisition unit for acquiring unknown CAD information including a CAD object; an analysis and extraction unit that analyzes the acquired unknown CAD information and extracts at least one CAD object; A generation unit that generates construction identification information corresponding to the CAD object based on the extracted CAD object and by referring to the CAD information; An estimation support system having the above.

[0078] As described above, by referring to the estimation information or CAD information having the association information instead of the graphic construction link table, it is possible to generate construction identification information (that is, the estimation information).

[0079] Fig. 20 is a schematic diagram showing a method of creating items in a graphic construction link table while having an AI engine learn pairs of CAD objects included in CAD information and construction identification information in the cost estimation information corresponding to the CAD objects as teaching data. Fig. 19 shows a method of creating teaching data for the AI ​​engine to learn, but Fig. 20 explains a technique of using this teaching data to have the AI ​​engine learn and create a table.

[0080] As shown in the figure, the estimation information ACI2 includes construction identification information (unit-hour code 3DBKOA01) and construction identification information (unit-hour code 3DBKOA02). The CAD information CADIN includes several CAD objects. These CAD objects (CAD information) and construction identification information (i.e., estimation information) are read into the trained AI engine AIE for learning. That is, the AI ​​engine is made to find the correct pair of CAD object and construction identification information from what has been read, and learn the pair as teacher data. In this way, the trained AI engine AIE2, which has been further trained, is completed. This trained AI engine AIE2 may be used as is, but it is preferable to generate the learned contents as items and include them in the graphic construction link table FCL5.

[0081] FIG. 21 is a schematic diagram showing a technique for including cost estimation information in the attribute information of a CAD object in CAD information while having an AI engine learn pairs of CAD objects included in CAD information and construction identification information in the cost estimation information corresponding to the CAD object as teacher data. As shown in the figure, the cost estimation information ACI2 includes construction identification information (unit-hour code 3DBKOA01) and construction identification information (unit-hour code 3DBKOA02). The CAD information CADIN includes several CAD objects. These CAD objects (CAD information) and construction identification information (i.e., cost estimation information) are read into the trained AI engine AIE3 for learning. That is, the AI ​​engine is made to find a correct pair of a CAD object and construction identification information from what has been read, and learns the pair as teacher data. In this way, a trained AI engine AIE4 that has been further trained is completed. This trained AI engine AIE4 may be used as it is, but it is preferable to generate the learned contents as items and include them in the figure construction link table FCL5. As shown in the figure, the attribute information ADIN1 of the CAD object includes ddd construction, 3DBK0A01, and quantity xxm3, while the attribute information ADIN2 of the CAD object includes ddd2 construction, 3DBK0A01, and quantity xym3.

[0082] In this way, if there is CAD information that includes CAD objects with attribute information that includes association information, it is possible to generate estimation information (construction identification information) from unknown CAD objects, even without a graphic construction link table or AI engine, as long as the attribute information contains an item that corresponds to the learned CAD object.

[0083] Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present invention. For example, the processes and functions included in each part and each step can be rearranged so as not to cause logical inconsistencies, and multiple means / parts and steps can be combined into one or divided. Alternatively, it should be noted that some components, functions, processes, steps, etc. of the device, method, program, etc. according to the present invention can be arranged on a remote server, etc. [Explanation of symbols]
