Is done.

  The cost calculation unit 102d of the terminal device 100 is a cost calculation unit that calculates a cost related to the integrated BIM model created by the integrated modeling unit 102b and a cost related to a modified BIM model described later. Specifically, the cost calculation unit 102d calculates the cost related to the integrated BIM model from the information related to the prices of the units and components constituting the elevator included in the integrated BIM model. In the present embodiment, the cost generated on the construction side and the cost generated on the elevator manufacturer side are calculated separately, but only the total amount may be calculated.

  The prediction information acquisition unit 102e of the terminal device 100 is a prediction information acquisition unit that acquires information regarding the prediction cost at the time of procurement of the member. For example, the prediction information acquisition unit 102e acquires various information such as the price fluctuation history of members, the social situation, the dispute situation, and the exchange rate accumulated in the storage unit 206 of the server device 200, and uses a predetermined algorithm. Calculate the estimated cost at the time of material procurement. The prediction information acquisition unit 102e is not limited to this example, and may directly acquire the above-described information or the prediction cost at the time of procurement of members from, for example, an external information organization or a website via the network 300.

  The model evaluation unit 102f of the terminal device 100 is used to determine the relative positions of the building and BIM parts included in the integrated BIM model and information on the arrangement of the building and BIM parts included in the integrated BIM model. Model evaluation means for evaluating an integrated BIM model based on information related to at least one member and evaluation conditions related to the BIM model.

  Specifically, the model evaluation unit 102f includes the cost generated on the construction side (first condition), the cost generated on the elevator manufacturer side (second condition), the elevator installation period (third condition), and the elevator installation time. The integrated BIM model is scored based on the five evaluation conditions of safety (fourth condition) and earthquake resistance of the elevator (fifth condition). The evaluation conditions may be less or more than five, and may be selectively increased or decreased, for example, by the user. For example, the model evaluation unit 102f may evaluate the integrated BIM model based only on the cost generated on the elevator manufacturer side by setting by the user.

  The cost generated on the building side is, for example, the cost of a member provided on the building side for construction of a building or installation of an elevator. The cost generated on the elevator manufacturer side is, for example, the cost of the elevator, peripheral devices, and members provided on the elevator manufacturer side for installing the elevator. The model evaluation unit 102f is based on information on the arrangement of the chassis and BIM parts, information on the cost of the member, which is information on the member, and the evaluation condition of the cost generated on the building side or the cost generated on the elevator manufacturer side, Evaluate the integrated BIM model.

  The elevator installation period is, for example, a period for elevator installation work. The safety of the elevator installation is, for example, the layout of the space for installation work, the number of caution information, etc., whether or not there is enough space for workers to perform work. Points are scored based on conditions. In addition, the safety | security at the time of maintenance of an elevator may be evaluation conditions. The earthquake resistance of an elevator is, for example, the earthquake resistance of an elevator installed in a building.

  The model evaluation unit 102f may adopt a predicted cost instead of the current cost for the cost generated on the building side and the cost generated on the elevator manufacturer side as the evaluation condition. In this case, the cost calculation unit 102d calculates, based on the prediction cost calculated by the prediction information acquisition unit 102e, a prediction cost related to the integrated BIM model created by the integrated modeling unit 102b and a prediction cost related to a modified BIM model described later. To do. The model evaluation unit 102f uses the prediction cost of the integrated BIM model calculated by the cost calculation unit 102d, uses information related to the arrangement of the chassis and BIM parts, information related to the prediction cost at the time of procurement of the member, which is information related to the member, The integrated BIM model is evaluated on the basis of the evaluation condition of the predicted cost generated in step 1 or the predicted cost generated on the elevator manufacturer side. Whether to use the current cost or the predicted cost in the evaluation of the model evaluation unit 102f is selected by the user, for example.

  The determination unit 102g of the terminal device 100 is a determination unit that determines whether or not the member for determining the relative position between the housing and the BIM part is a standard product based on the dimension information extracted from the standard condition database 206b. is there.

  Hereinafter, an example of determination will be described. The determination unit 102g determines whether the member 14 in the integrated BIM model in the example of FIG. 4 is a standard product based on the dimension information transmitted from the server device 200. Since the member 14 is a custom-made product, it is out of the range to be determined as a standard product. For this reason, the determination unit 102g determines that the member 14 is a custom-made product (non-standard product).

  Returning to FIG. 1, the modified modeling unit 102h of the terminal device 100 integrates the arrangement of the housing and BIM parts and the members so that an evaluation result higher than the evaluation result of the integrated BIM model by the model evaluation unit 102f is obtained. It is a modified modeling means for creating at least one modified BIM model modified from the BIM model.

  If the determination unit 102g determines that the member is not a standard product, the correction modeling unit 102h changes the arrangement of the housing and the BIM parts using a predetermined algorithm, and changes the type, size, arrangement, and quantity of the member. By modifying, a modified BIM model that can obtain an evaluation result higher than the evaluation of the integrated BIM model under at least one of the above five evaluation conditions is created. For example, by adopting a standard product in place of the member 14, a modified BIM model capable of obtaining a higher evaluation result than the integrated BIM model at a cost (second condition) generated on the elevator manufacturer side is created.

  FIG. 5 is an exemplary diagram schematically showing an example of the modified BIM model in the first embodiment. As shown in FIG. 5, an example of the modified BIM model includes a member 21 and a plurality of members 22 instead of the member 14 in the example of FIG. The members 21 and 22 are used to determine the relative positions of the chassis 11 and the BIM parts (the car 12 and the guide rail 13), as with the member 14.

  The member 21 is a beam extending between two opposing walls of the housing 11. The member 21 is included in the BIM model on the building side. The plurality of members 22 are brackets that fix one guide rail 13 to the wall of the housing 11 and fix the other guide rail 13 to the member 21 that is a beam. The member 22 is included in the BIM part.

  The member 22 is a standard product. In the example of FIG. 5, the member 22 which is a standard product smaller than the member 14 which is a custom-made product can be adopted by providing the member 21 which is a beam on the construction side.

  The members used to determine the relative positions of the chassis 11 and the BIM parts (the car 12 and the guide rail 13) are not limited to brackets or beams. For example, the member may be another member such as H-shaped steel.

  Returning to FIG. 1, the correction modeling unit 102 h transmits the creation condition obtained by a predetermined algorithm to the server device 200 via the creation condition transmission unit 102 a, for example. Then, the modification modeling unit 102h creates a modified BIM model in which the BIM parts including the members 21 and 22 which are standard products received from the server device 200 are incorporated in the BIM model of the building stored in the BIM model database 106a. create.

  In the above example, the modified modeling unit 102h obtains an evaluation result higher than the evaluation result by the model evaluation unit 102f based on the cost (second condition) generated on the elevator manufacturer side, so that the modified BIM model (first A modified model was created. The modified modeling unit 102h further creates a modified BIM model that can obtain an evaluation result higher than the evaluation result of the model evaluation unit 102f based on other evaluation conditions. For example, the modified modeling unit 102h employs a member having higher strength instead of the member 14, so that the evaluation result higher than the evaluation result of the model evaluation unit 102f is obtained based on the earthquake resistance (fifth condition) of the elevator. A modified BIM model (second modified model) is created so as to be obtained. The member in the modified BIM model may be a custom-made product (non-standard product) as long as the modified BIM model can obtain an evaluation result higher than the evaluation result by the model evaluation unit 102f.

  Note that the chassis and BIM parts in the modified BIM model remain the integrated BIM model chassis and BIM parts. For this reason, the BIM parts in the modified BIM model have specifications that satisfy customer specification conditions. The chassis and BIM parts in the modified BIM model may be changed from the integrated BIM model chassis and BIM parts.

  The model evaluation unit 102f evaluates at least one modified BIM model created by the modified modeling unit 102h based on the five evaluation conditions in the same manner as the integrated BIM model. At this time, the cost calculation unit 102d calculates a cost or a predicted cost related to the modified BIM model. The modified BIM model obtains an evaluation result higher than the evaluation result of the integrated BIM model based on at least one evaluation condition. However, under other evaluation conditions, the evaluation result of the modified BIM model may be lower than the evaluation result of the integrated BIM model.

  The display control unit 102 i of the terminal device 100 is a display control unit that displays the evaluation result of the model evaluation unit 102 f on the display unit 114. Specifically, the display control unit 102i causes the display unit 114 to display an operation screen including various results such as the evaluation result of the model evaluation unit 102f and the modified BIM model created by the modified modeling unit 102h.

  FIG. 6 is an exemplary diagram illustrating an example of an operation screen according to the first embodiment. For example, the display control unit 102i causes the display unit 114 to display an operation screen 50 as illustrated in FIG. In the example of FIG. 6, the operation screen 50 includes a model display unit 51, a file reference form 52, an output button 53, and a decision button 54.

  The model display unit 51 displays various information on the integrated BIM model and the modified BIM model. The file reference form 52 is a form for reading a data file in which the integrated BIM model is stored. The output button 53 is a button for determining an integrated BIM model and creating a modified BIM model. The determination button 54 is a button for determining an integrated BIM model or a modified BIM model to be adopted.

  For example, when the address of the data file storing the integrated BIM model is input to the file reference form 52, the model evaluation unit 102f evaluates the integrated BIM model, and various information on the integrated BIM model is displayed on the model display unit 51. Is displayed. In the present embodiment, when the integrated BIM model is created by the integrated modeling unit 102b, the integrated BIM model is automatically evaluated, but the created integrated BIM model is evaluated using the file reference form 52. It may be broken.

  When an input to the output button 53 is detected, determination by the determination unit 102g, creation of at least one corrected BIM model by the correction modeling unit 102h, and evaluation of the corrected BIM model by the model evaluation unit 102f are performed. Various information of the modified BIM model is displayed. The user can compare the integrated BIM model displayed on the model display unit 51 with at least one modified BIM model.

  When the determination unit 102g determines that the member is not a standard product and the corrected modeling unit 102h creates a corrected BIM model, the display control unit 102i displays the corrected BIM model on the model display unit 51. On the other hand, if the determination unit 102g determines that the member is a standard product, or if the correction modeling unit 102h cannot create a corrected BIM model, the display control unit 102i confirms that there is no problem with the integrated BIM model. A message to be displayed is displayed on the display unit 114.

  In the model display unit 51, a radio button 51a, an attribute table 51b, an attention information list button 51c, an option list button 51d, a graph 51e, and a thumbnail image 51f are displayed for each integrated BIM model and modified BIM model.

  The radio button 51a is used to select one of the integrated BIM model and the modified BIM model. When an input to the enter button 54 is detected in a state where the corrected BIM model is selected by the radio button 51a, the selected corrected BIM model is adopted, and the subsequent process proceeds based on the selected corrected BIM model. . When an input to the determination button 54 is detected in a state where the integrated BIM model is selected by the radio button 51a, the subsequent steps proceed based on the integrated BIM model.

  The attribute table 51b is a table that displays various attributes related to the integrated BIM model and the modified BIM model. In the example of FIG. 6, the attribute table 51b includes the total cost, the difference from the integrated BIM model, the cost generated on the construction side, the cost generated on the elevator manufacturer side, and the adoption of a custom-made product regarding the integrated BIM model and the modified BIM model. Display presence or absence. As described above, the display control unit 102i causes the display unit 114 to display the difference between the cost or the prediction cost related to the integrated BIM model and the cost or the prediction cost related to the modified BIM model. For this reason, the user can confirm at a glance how much the cost is reduced by the modified BIM model.

  FIG. 7 is an exemplary diagram illustrating an example of an attention information list screen according to the first embodiment. When an input to the caution information list button 51c is detected, the display control unit 102i displays a caution information list screen 60 (caution information display screen) as shown in FIG. 7 based on the caution information transmitted from the server device 200. 114 is displayed.

  The attention information list screen 60 displays attention information 61 corresponding to the arrangement conditions of the chassis, the BIM parts, and the members in the integrated BIM model or the modified BIM model. The caution information list screen 60 displays caution information 61 in installation work and caution information 61 in maintenance work, respectively. The attention information list screen 60 can be used as an installation sheet and a maintenance sheet.

  FIG. 8 is an exemplary diagram illustrating an example of an option information list screen according to the first embodiment. When an input to the option list button 51d is detected, the display control unit 102i displays an option list screen 70 (option information display screen) as shown in FIG. 8 on the display unit 114 based on the option information transmitted from the server device 200. Display.

  The option list screen 70 displays option information 71 corresponding to building conditions related to the BIM model. In this way, the display control unit 102i causes the display unit 114 to display the option information extracted by the option information extraction unit 202g of the server device 200.

  When an input to the detail button 72 corresponding to the option information 71 is detected, the display control unit 102i displays details regarding the option information 71, such as a proposed reason, a price of a device to be added or changed, a preview, and the like. 114 is displayed. When an input to the execution button 73 corresponding to the option information 71 is detected, the integrated modeling unit 102b or the modified modeling unit 102h recreates the integrated BIM model or the modified BIM model to which the option is applied.

  When the modified BIM model is created by the modified modeling unit 102h, the model information transmitting unit 102c transmits model information indicating the characteristics of the modified BIM model to the server device 200. The attention information extraction unit 202f extracts the attention information corresponding to the arrangement condition included in the model information of the modified BIM model from the attention information database 206c. The option information extraction unit 202g extracts option information corresponding to building conditions included in the model information of the modified BIM model from the option information database 206d. The display control unit 102 i can display the attention information and option information of the modified BIM model received from the server device 200 on the display unit 114.

  Returning to FIG. 6, the graph 51 e is a graph showing the evaluation result of the integrated BIM model or the modified BIM model. Specifically, the graph 51e shows the cost generated on the construction side (first condition), the cost generated on the elevator manufacturer side (second condition), the installation period of the elevator (third condition), and the safety when installing the elevator It is a radar chart which shows the evaluation result of an integrated BIM model or a modified BIM model in five evaluation conditions, such as performance (fourth condition) and earthquake resistance of the elevator (fifth condition). As described above, the display control unit 102i causes the display unit 114 to display the attribute table 51b and the graph 51e as the evaluation results of the integrated BIM model and the modified BIM model of the model evaluation unit 102f.

  The thumbnail image 51f is an image showing an integrated BIM model or a modified BIM model. When the model display unit 51 displays the attribute table 51b, the graph 51e, and the thumbnail image 51f, the user can easily compare the integrated BIM model and the modified BIM model.

  Next, the operation of the BIM system 1 according to the first embodiment will be described. FIG. 9 is an exemplary flowchart showing a specific example of processing executed in the BIM system 1 of the first embodiment.

  As shown in FIG. 9, in the first embodiment, first, the terminal device 100 transmits a BIM parts creation condition to the server device 200 (S1). Then, the server device 200 receives the creation condition transmitted by the terminal device 100 in S1 (S2).

  The server device 200 uses the part information stored in the parts information database 206a to create a BIM part corresponding to the creation condition received in S2 (S3). Then, the server device 200 transmits the BIM part created in S3 to the terminal device 100 (S4).

  The terminal device 100 receives the BIM part transmitted by the server device 200 in S4 (S5). Then, the terminal device 100 incorporates the BIM part received in S5 into the building BIM model stored in the BIM model database 106a, and creates an integrated BIM model (S6). Then, the terminal device 100 transmits model information indicating the characteristics of the integrated BIM model created in S6 to the server device 200 (S7).

  The server device 200 receives the model information transmitted by the terminal device 100 in S7 (S8). Then, the server device 200 refers to the standard condition database 206b, the caution information database 206c, and the option information database 206d, and extracts dimension information, caution information, and option information corresponding to the model information (S9).

  The server device 200 transmits the dimension information, the caution information, and the option information extracted in S9 to the terminal device 100 (S10). Then, the terminal device 100 receives the dimension information, the caution information, and the option information transmitted by the server device 200 in S10 (S11).

  The terminal device 100 calculates the cost of the integrated BIM model created in S6 (S12). And the terminal device 100 evaluates an integrated BIM model based on the information on arrangement | positioning of the housing and BIM parts in an integrated BIM model, the information regarding a member, and evaluation conditions (S13). Then, the terminal device 100 causes the display unit 114 to display an operation screen on which the integrated BIM model evaluation result is displayed on the model display unit 51 (S14).

  The terminal device 100 determines whether an input to the output button 53 on the operation screen displayed in S14 is detected (S15). When the input to the output button 53 is detected (Yes in S15), the terminal device 100 determines the relative positions of the housing and the BIM parts in the integrated BIM model based on the dimensional information transmitted by the server device 200. It is determined whether the member for this is a standard product (S16).

  When it is determined that the member is not a standard product (No in S16), the terminal device 100 is configured to arrange the housing and the BIM parts so that an evaluation result higher than the evaluation result of the integrated BIM model by the model evaluation unit 102f is obtained. It is determined whether or not the member can be corrected (S17). When it is determined that the arrangement of the casing and the BIM parts and the member can be corrected (Yes in S17), the terminal device 100 can obtain an evaluation result higher than the evaluation result of the integrated BIM model by the model evaluation unit 102f. In addition, at least one modified BIM model in which the arrangement of the housing and the BIM parts and the members are modified from the integrated BIM model is created (S18).

  The terminal apparatus 100 transmits a creation condition to the server apparatus 200 as necessary, and receives a BIM part from the server apparatus 200 to create a modified BIM model, as in S1 to S5. Then, the terminal device 100 transmits model information indicating the characteristics of the modified BIM model created in S18 to the server device 200 (S19).

  The server device 200 receives the model information of the modified BIM model transmitted by the terminal device 100 in S19 (S20). Then, the server device 200 refers to the standard condition database 206b, the caution information database 206c, and the option information database 206d, and extracts dimension information, caution information, and option information corresponding to the model information of the modified BIM model (S21). ).

  The server device 200 transmits the dimension information, the caution information, and the option information extracted in S21 to the terminal device 100 (S22). The terminal device 100 receives the dimension information, the caution information, and the option information transmitted by the server device 200 in S22 (S23).

  The terminal device 100 calculates the cost of the modified BIM model created in S18 (S24). Then, the terminal device 100 evaluates the modified BIM model based on the information on the arrangement of the chassis and BIM parts in the modified BIM model, information on the members, and the evaluation conditions (S25). Then, the terminal device 100 causes the display unit 114 to display an operation screen on which the evaluation result of the modified BIM model is displayed on the model display unit 51 (S26).

  When the display result of the modified BIM model is displayed on the operation screen in S26, the terminal device 100 accepts a selection operation for one of the integrated BIM model and the modified BIM model (S27). The user can select one of the integrated BIM model and the modified BIM model using the radio button 51 a of the model display unit 51.

  The terminal device 100 determines whether or not an input to the determination button 54 has been detected (S28). If the terminal device 100 determines that the input to the determination button 54 has not been detected (No in S28), the terminal device 100 returns to S15 and determines whether or not the input to the output button 53 has been detected. For example, the user may change the evaluation condition and create a modified BIM model again.

  If the terminal device 100 determines that an input to the determination button 54 has been detected (Yes in S28), the terminal device 100 ends the above processing, and proceeds on the basis of the selected integrated BIM model or modified BIM model.

  If it is determined in S15 that an input to the output button 53 has not been detected (No in S15), if it is determined in S16 that the member is a standard product (Yes in S16), or the integrated BIM model cannot be corrected in S17. If it is determined (No in S17), the terminal apparatus 100 proceeds to S28 and determines whether or not an input to the determination button 54 is detected. Therefore, when an input to the determination button 54 is detected (Yes in S28), the terminal device 100 ends the above processing, and the subsequent steps proceed based on the integrated BIM model.

  As described above, in the BIM system 1 according to the first embodiment, the model evaluation unit 102f determines the relative position between the building body and the BIM part and the information on the arrangement of the building body and the BIM part. The integrated BIM model is evaluated based on the information regarding the member and the evaluation condition regarding the integrated BIM model. The display control unit 102i causes the display unit 114 to display the evaluation result of the model evaluation unit 102f. Thereby, the integrated BIM model can be guided to the design according to the evaluation condition based on the evaluation result of the model evaluation unit 102f. Therefore, the design method can be unified regardless of the designer.

  In the above description, the cost that can be reduced by using the standard member is treated as the evaluation condition. However, the condition of whether or not the member is a standard product is also one of the evaluation conditions. For example, the determination unit 102g evaluates (determines) the integrated BIM model based on information on the dimensions of the member and an evaluation condition indicating whether the member is a standard product. The display control unit 102i causes the display unit 114 to display an operation screen 50 including an attribute table 51b indicating whether or not a custom-made product is employed, that is, whether or not the member is a standard product.

  The modified modeling unit 102h obtains at least one modified BIM model in which the arrangement of the frame and the BIM parts and the members are modified from the integrated BIM model so that an evaluation result higher than the evaluation result by the model evaluation unit 102f is obtained. create. Thereby, for example, an integrated BIM model in which the design method is easily unified can be obtained simply by replacing a modified BIM model with an integrated BIM model.

  The information regarding the member includes information regarding the cost of the member. The evaluation condition includes a condition regarding cost. That is, the evaluation of the integrated BIM model and the creation of the modified BIM model are performed using the change in the arrangement of the housing and the BIM parts and the cost that changes due to the change in the member as the evaluation conditions. Further, the display control unit 102i causes the display unit 114 to display the difference between the cost related to the integrated BIM model and the cost related to the modified BIM model. As a result, an integrated BIM model with reduced costs can be obtained, and the designer can grasp the reduced costs and learn a low-cost design.

  The information regarding the member includes information regarding the predicted cost when the member is scheduled to be procured. The prediction information acquisition unit 102e acquires information related to the predicted cost of the member. The evaluation condition includes a condition related to the predicted cost. In other words, the integrated BIM model is evaluated and the modified BIM model is created using the estimated cost as an evaluation condition. Thereby, even if the period from the time of evaluation to the time of scheduled procurement of members is long, an integrated BIM model in which the final cost is reduced can be obtained. Furthermore, it is possible to reduce the effort for the designer to calculate and investigate the predicted cost.

  The correction modeling unit 102h creates a first correction BIM model so that an evaluation result higher than the evaluation result by the model evaluation unit 102f is obtained based on a certain first condition (for example, cost generated on the elevator manufacturer side). At the same time, the second modified BIM model is created so that an evaluation result higher than the evaluation result by the model evaluation unit 102f is obtained based on the second condition (for example, the cost generated on the building side). Thereby, the integrated BIM model which considered the balance of several evaluation conditions like the cost of a building side and the cost of an elevator maker, for example can be obtained.

  The evaluation condition includes a condition related to the arrangement state of the space for at least one of the installation work and the maintenance work in the integrated BIM model. That is, the evaluation of the integrated BIM model and the creation of the modified BIM model are performed using the space for installation work and maintenance work as evaluation conditions. This makes it possible to obtain an integrated BIM model that facilitates installation work and maintenance work.

  The attention information extraction unit 202f extracts the attention information corresponding to the arrangement conditions of the housing, the BIM parts, and the members from the attention information database 206c. Thereby, it is possible to prompt the designer to design for avoiding troubles in the installation work and the maintenance work, and to easily create a sheet for the installation work and the maintenance work.

  The option information extraction unit 202g extracts option information corresponding to building conditions in the BIM model from the option information database 206d. As a result, the integrated BIM model can be guided to a design with higher added value by the option information automatically extracted according to the building conditions of the BIM model. Therefore, the design method can be unified regardless of the designer.

(Second Embodiment)
Next, a second embodiment (a server-driven function distribution type BIM system) will be described.

The integrated BIM model is evaluated based on the information regarding at least one member for determining the relative position and the evaluation condition regarding the integrated BIM model. Then, the determination unit 1202k determines whether or not the member is a standard product based on the dimension information extracted from the standard condition database 206b by the standard condition extraction unit 202e.

  When the determination unit 1202k determines that the member is not a standard product, the correction modeling unit 1202l of the server apparatus 1200 includes the arrangement of the housing and the BIM parts so that an evaluation result higher than the evaluation result by the model evaluation unit 1202j is obtained. At least one modified BIM model is created from the integrated BIM model. As in the first embodiment, the modified modeling unit 1202l includes a cost generated on the construction side (first condition), a cost generated on the elevator manufacturer side (second condition), an elevator installation period (third condition), and an elevator In order to obtain a higher evaluation result than the evaluation result by the model evaluation unit 1202j, based on the five evaluation conditions of safety during installation (fourth condition) and earthquake resistance of the elevator (fifth condition) A modified BIM model is created.

  The display control unit 1202m of the server apparatus 1200 causes the display unit 114 to display the evaluation result of the model evaluation unit 1202j. The display control unit 1202m instructs the terminal device 1100 to display the operation screen 50 as an evaluation result of the model evaluation unit 1202j on the display unit 114. The display control unit 1202m also causes the display unit 114 to display the difference between the cost or predicted cost related to the integrated BIM model and the cost or predicted cost related to the modified BIM model. The display control unit 1202m further causes the display unit 114 to display the attention information extracted from the attention information database 206c by the attention information extraction unit 202f and the option information extracted from the option information database 206d by the option information extraction unit 202g.

  Note that other configurations and operations of the second embodiment are substantially the same as those of the first embodiment, and thus description thereof is omitted here.

  As described above, also in the BIM system according to the second embodiment, the model evaluation unit 1202j includes the information on the layout of the building frame and the BIM parts, the frame, and the BIM system according to the first embodiment.

The display control unit 1202m causes the display unit 114 to display the evaluation result of the model evaluation unit 1202j. Thus, the integrated BIM model can be guided to the design according to the evaluation condition based on the evaluation result of the model evaluation unit 1202j. Therefore, the design method can be unified regardless of the designer.

Next, a third embodiment (stand-alone BIM device) will be described. In the third embodiment, unlike the first and second embodiments in which various functions related to BIM and the like are distributed and provided in two devices connected via the network 300, the BIM and the like are related. Various functions are provided in a single device. In the following, overlapping descriptions of configurations, operations, and effects common to the first embodiment and the second embodiment are omitted as much as possible.

  The BIM device 400 according to the third embodiment independently realizes functions equivalent to those of the first embodiment and the second embodiment. That is, the storage unit 406 of the BIM device 400 according to the third embodiment has five types of databases (part information database 406a, BIM model database 406b, standard condition database 406c) equivalent to those in the first embodiment and the second embodiment. , An attention information database 406d and an option information database 406e).
