=== This embodiment ===
A management method (method for confirming progress, etc.) using the management system 1 according to the present embodiment will be described with reference to the drawings. FIG. 1 is a configuration diagram of a management system 1 according to the present embodiment. In the following, first, each part constituting the management system 1 will be described, and then a management method using the management system 1 will be described.

The management system 1 according to the present embodiment includes BIM software 2, a storage unit 10, a state processing unit 20, and a display unit 30.

BIM software 2 is software that operates on a computer and has a function of creating a BIM model 2a that is a three-dimensional model of a structure (building or the like). The BIM model 2a is composed of a plurality of parts (corresponding to constituent elements). That is, the BIM model 2a is a three-dimensional (3D) model of the structure created by the BIM software 2 on the computer, and is a collection of parts constituting the structure.

In addition, the parts of the BIM model 2a have various information such as materials and finishes in addition to the shape represented by the 3D model, and each part is advanced (more detailed information is set and embodied). By doing so, the BIM model 2a progresses (the degree of perfection of the BIM model 2a increases).

The parts in the BIM model 2a show the advanced state, the position state showing the position and size information of the BIM model 2a, and the attribute information (for example, when the part is a door, the door material and fireproof specifications). It has an attribute state indicating (information such as the presence or absence of). The position state and the attribute state are each quantified as the degree of materialization according to the degree of progress (materialization) of the part, and such numerical values are based on LOD (Level Of Development) (details will be described later). do).

The attribute information common to a plurality of parts (for example, an information element that manages that the material of a plurality of walls (parts) is concrete) is set as a common attribute on the BIM model 2a separately from the attribute information of the parts. There is also BIM software that is managed, and the degree of progress (materialization) is also quantified based on the LOD as the degree of materialization, similar to the attribute state of parts.

The storage unit 10 has a site classification information storage unit 11, a state index storage unit 12, and a state storage unit 13, and is a portion that stores various information. As the storage unit 10, for example, a hard disk of a computer, a RAM (Random Access Memory), or the like can be used.

The part classification information storage unit 11 stores information for classifying parts into parts (hereinafter, also referred to as part classification). FIG. 2 is an example of information stored in the site classification information storage unit 11, FIG. 2a is an example of site classification data 11a, and FIG. 2b is an example of site classification reference data 11b.

The part classification data 11a stores the name of the part classification as basic data for classifying the parts, and as shown in FIG. 2a, the outer wall, the outer door, the outer window, and the like are stored. Then, the parts of the BIM model 2a are classified, for example, the part classification of the parts 1 to 5 is the outer wall, and the part classification of the parts 6 to 10 is the outer door.

The site classification standard data 11b stores the criteria for classifying parts into the site classification, and as shown in FIG. 2b, the items (category, inside / outside, etc.) corresponding to the site classification (outer wall, outer door, etc.). And the reference value (wall, outside, etc.) of each item is saved. Then, based on this information, for the parts of the BIM model 2a, for example, the category of the part 1 is the wall and the inside / outside is the outside, so that the part classification of the part 1 is the outer wall and the category of the part 2 is the door. Since the inside / outside is the outside, the part classification of the part 2 is classified as an external door.

The state index storage unit 12 stores data in which the degree of progress of parts and the like are quantified. FIG. 3 is an example of information stored in the state index storage unit 12, FIG. 3a is an example of materialization degree data 12a, and FIG. 3b is a target value (corresponding to a target site classification progress index). It is an example of the data 12b, and FIG. 3c is an example of the parameter data 12c.

Here, in the present embodiment, a numerical value based on LOD (hereinafter, also referred to as a state index value) is used for quantifying the degree of materialization (progress) of the component. LOD (Level Of Development) was established by the American Institute of Architects in 2008 as a standard for the progress of BIM models. In 2013, the LOD Specification was released, and almost every year since then. It has been updated.

In this LOD specification, the standard of progress is divided into 6 levels, and the standard of progress of LOD 100, 200, 300, 350, 400, and 500 is determined. It should be noted that the larger the value of LOD, the more advanced it is, and the larger the value, the closer the BIM model is to completion.

The degree of materialization (progress) may be quantified by using the numerical value of the LOD specification as it is, but in this embodiment, the level is set more finely in addition to the 6 levels shown in the LOD specification. The degree of materialization (progress) is quantified using the state index values.

As shown in FIG. 3a, the materialization degree data 12a stores the materialization degree indicating the degree of progress of the parts, and as described above, the materialization degree is set by the state index value (LOD specification). A finer level than the book is set). For example, between LOD200 and 300, the degree of reification of LOD225, 250, and 275 is set.

As shown in FIG. 3b, the target value data 12b includes a site classification (outer wall, external door, etc.), a base value (a reference value for progress management, which is 100 based on the LOD specification in this embodiment), and a target value. And are set.

The target value is a state index value and is set as a value at which the phase of the project is completed. In FIG. 3b, it is set for phases 0 to 2. For example, on the outer wall, phase 1 is completed when the state index value reaches 225.

The phase according to the present embodiment is one of the steps obtained by dividing the progress of the project into stepwise steps (for example, the entire process of the project is the first step (phase 0) to the third step. (Phase 2) One of the three steps (for example, the first step (Phase 0)).

Further, since the part classification to be managed differs depending on the project and the BIM model, it is preferable to provide a state management section and select whether to manage or not to manage, as shown in FIG. 3b. Further, as shown in FIG. 3b, it is preferable that the weighting can be set according to the importance of the site classification and the like.

The parameter data 12c indicates how much the degree of materialization (progress) of a certain parameter of a component is determined by the state index value (if it is input and the conforming condition is satisfied). As shown in FIG. 3c, the parameter data 12c corresponds to the site classification (outer wall, external door, etc.), the parameter ID (named for convenience for aggregation for each parameter ID), and the above-mentioned target value. The parameters and the conditions for conforming the parameter values to satisfy the target values are set and saved. For example, the parameter of the target value 225 of the outer wall is the thickness, and the presence or absence of the specification is a conforming condition, so if the thickness is input to the outer wall, the thickness which is the parameter of the outer wall has reached the target value 225. Become.

The state storage unit 13 stores information regarding the degree of progress of the current BIM model 2a. FIG. 4 is an example of information stored in the state storage unit 13, FIG. 4a is an example of component state data 13a, and FIG. 4b is an example of parameter input state data 13b.

As shown in FIG. 4a, the component state data 13a stores the element Id (Id uniquely possessed by the component), the element name, the part classification, the state classification, the progress index, the input person, and the input date and time. .. Here, the progress index is a state index value that reflects the degree of concreteness of the part and the approval stage of the degree of concreteness, and is a numerical value to be referred to when managing the part (progress confirmation). See FIG. 7d. Details will be described later). For example, in FIG. 4a, when confirming the progress of the position state of the wall 1, it is confirmed that the progress index is 230.

As shown in FIG. 4b, the parameter input state data 13b stores the element Id, the part classification, the parameter ID, the target value, and the conforming state. Here, the conforming state indicates whether or not the parameter shown in the parameter data 12c (see FIG. 3c) satisfies the above-mentioned conforming condition, and if conforming, the parameter progresses to the target value. It will be. For example, in FIG. 4b, since all three parameter outer wall attributes 2 of the target value 225 of the outer wall are “fit”, this parameter has progressed to the target value 225 (outside the parameter of the target value 225 of the outer door). The case where one of the three is "conforming" as in the door attribute 3 will be described later).

The display unit 30 is a part where the result calculated by the state processing unit 20 is displayed, and is, for example, a part where the user confirms the progress rate of the BIM model 2a. As the display unit 30, for example, a computer display or the like can be used.

<<< Management method using management system 1 >>>
Next, an example of a management method (method for confirming progress, etc.) using the management system 1 will be described. First, the registration information for managing the BIM model 2a is pre-registered in the storage unit 10 of the management system 1 (corresponding to the pre-registration acceptance step). FIG. 5 is a flowchart showing an example of the procedure for pre-registering registration information.

<Pre-registration of registration information>
Hereinafter, an example of the procedure for pre-registering registration information will be described. First, the site classification data 11a shown in FIG. 2a is registered (step S1). The information of the part classification data 11a is not limited to the information that the BIM software 2 has in advance, and may be freely set as necessary for managing the progress of the BIM model 2a.

Next, the site classification reference data 11b shown in FIG. 2b is registered (step S2). The information of the site classification standard data 11b is not limited to the information that the BIM software 2 has in advance, and a site classification standard for use in classification may be added as needed.

In addition, the number of items (reference values) used when classifying into the site classification may be freely set. That is, it is not limited to the two shown in FIG. 2b, and may be, for example, only one of the reference values of the category, or may be three or more.

Next, the reification degree data 12a shown in FIG. 3a is registered (step S3). In the present embodiment, the materialization degree data 12a shown in FIG. 3a is set using the state index value, and the materialization degree data 12a, the materialization degree option of the position state, and the materialization degree option of the attribute state are used. (See FIGS. 7b and 7c. Details will be described later).

Next, the target value data 12b shown in FIG. 3b is registered (step S4). In a building project, it often takes a long time from planning to design and construction, so as mentioned above, it is common to divide the progress of the project into phases, and the target value for each phase. (It is not necessary to set the target value (phase division), but it is common to set the target value (phase division)).

That is, in the present embodiment, the project is divided into phases for each part classification, and the base value and the target value for each phase are set using the state index value. In other words, the management method using the management system 1 has a pre-registration acceptance step in which the computer accepts the pre-registration of the target value set for each of a plurality of phases. In this pre-registration acceptance step, for example, the target value of Phase 1 of the outer wall is set to 225.

Next, the parameter data 12c shown in FIG. 3c is registered (step S5). In the present embodiment, since the project is divided into a plurality of phases for each part classification, a target value and a conforming condition for satisfying the target value are set for each parameter to be input in the part classification.

In other words, the management method using the management system 1 is a target value set for each of a plurality of phases of the project corresponding to the BIM model 2a and for each part classification of the BIM model 2a, and is a target value. Each has a pre-registration acceptance step in which the computer accepts pre-registration of the target value associated with the site classification parameter. In this pre-registration acceptance step, for example, when the parameter to be input to the outer wall is the thickness, the conformity condition for satisfying the target value 225 is set to be explicit or not.

The parameter may be a parameter of the part (attribute information possessed by the part itself, for example, the paint color of the fitting), or may be a parameter of a common attribute (for example, the material of the fitting). Further, the parameters are not limited to the parameters that the BIM software 2 has in advance, and may be added as needed.

<Calculation of progress index>
Next, it is a state index value that reflects the degree of concreteness of the part and the approval stage of the degree of concreteness described above, and is a numerical value to be referred to when managing the part (progress confirmation). An example of calculating the progress index will be described with reference to a figure. It should be noted that the progress index is calculated to be higher as the level of the degree of reification progresses and as the stage until approval progresses.

FIG. 6 is an example of a flowchart for calculating the progress index and calculating the progress rate of the BIM model 2a using the progress index. FIG. 7 shows an example of data related to the calculation of the progress index, FIG. 7a is an example of data showing a state in which the component and the progress index are associated, and FIG. 7b shows a concreteness option of the position state. 7c is an example of the data showing the degree of concreteness and the choice of the degree of concreteness of the attribute state, and FIG. 7d is the example of the data showing the degree of progress index of the attribute state. This is just one example.

The progress index according to this embodiment is calculated as follows. First, the degree of materialization is determined by selecting the degree of materialization option shown in FIGS. 7b and 7c in which the degree of materialization is indicated for each level. For example, if "determination of basic classification" is selected as the materialization degree option of the attribute state of the part, the materialization degree of this part is 230. It should be noted that the degree of materialization may be selected, the corresponding degree of materialization option may be displayed, and the degree of materialization option may be selected. In other words, select "230", which is the degree of concreteness, as an option, and have them present "determination of basic classification", which is the corresponding degree of concreteness option, and confirm that there is no problem with such specificity degree option. You may (you may select such a degree of reification option).

Next, the progress index is determined by selecting the approval stage option showing the stage up to the approval of the degree of reification shown in FIG. 7d for each stage. For example, if "determine basic classification" is selected as the concreteness option of the attribute state of the part and "designer work completed" is selected as the approval stage option, the progress index of this part is 210. .. Then, as shown in FIG. 7a, the progress index is associated and stored for each component.

That is, in the management method using the management system 1, a plurality of concreteness degree options in which the degree of concreteness of the parts of the BIM model 2a is expressed by level and approval in which multiple stages up to the approval of the degree of concreteness are expressed are expressed in stages. The stage option was selected as an option presentation step (step S10) in which the computer presents, and a selection acceptance step (step S11) in which the computer accepts a selection from the presented reification degree options and approval stage options. The progress index calculation step (step S12) in which the computer calculates the progress index indicating how much the part is determined based on the degree of reification and the approval stage, and the computer uses the calculated progress index for the part. It has an association step (step S13) and an association.

In addition, in FIG. 7d, work completed or approval is described as an approval stage option, but the present invention is not limited to this, and for example, "the confirmer is thinking" and "the approver thinks NG". The detailed intention of the input person may be reflected as a value.

Further, the selection of the specificity degree option and the approval stage option described above is performed by presenting these options to the input person and having the input person select one of them. Since the progress index is determined by selecting the approval stage for each degree of materialization, the input person selects the degree of materialization and the approval stage at the same time. Thereby, for example, it is possible to indicate that the approval stage of the degree of concreteness “230” is “approved”. FIG. 7d is a table showing the degree of reification and the approval stage, and the degree of progress index may be determined by each input independently. Here, the input person is an operator, a designer, a confirmer, an approver, and the like.

Further, although the input person and the input date and time items of the position state and the attribute state shown in FIG. 7a may not be provided, the information source of the progress index and the input date and time are clarified (the accuracy of the progress index is higher). (Because it will be expensive), it is preferable to provide a section for the input person and the input date and time.

Further, the progress index associated with each component is stored in the storage unit 10, but when stored, it is stored as component state data 13a as shown in FIG. 4a. That is, the progress index is stored in association with other data such as site classification.

Then, the process of classifying the parts associated with the progress index into the site classification may be performed at the stage of storing the progress index (step S13), and for example, the site classification progress index described later may be performed. It may be performed by collating with the site classification reference data 11b at the stage of performing the calculation (step S14).

(About calculation of progress rate of BIM model 2a using progress index)
After calculating the progress index, next, the progress rate of the BIM model 2a using the progress index is calculated. In the present embodiment, the site classification progress index is calculated from the progress index, and the progress rate indicating the progress of each phase (hereinafter, also referred to as the phase progress rate) is calculated from the site classification progress index, and the phase progress rate is calculated. The progress rate of the BIM model 2a is calculated from.

First, the progress index associated with the parts is averaged for each site classification, and the site classification progress index for each site classification is calculated (step S14). FIG. 8 is an example of the calculation result of the site classification progress index. As shown in FIG. 8, the site classification progress index is calculated for each site classification, state classification, and target value. For example, when the site classification is the outer wall, the state classification is the position state, and the target value is 225. , The calculated site classification progress index is 223.

That is, in the management method using the management system 1, the parts belong to one of a plurality of types of part classifications, and the progress index associated with the parts belonging to the common part classifications is averaged for each part classification. It has a part classification progress index calculation step in which a computer calculates the part classification progress index.

Here, the site classification progress index is calculated for each of a plurality of phases (for each target value) of the project corresponding to the BIM model 2a. That is, when the part classification progress index is calculated, if the progress index of the part is larger than the target value of the calculated phase, for example, only the part 1 is greatly progressed among the parts of the BIM model 2a. When the progress index of the component 1 is 240 and the target value of the phase to be calculated is 225, it is necessary to calculate the site classification progress index with the progress index of the component 1 as 225. Then, it is possible to suppress an excessive increase in the site classification progress index by the component 1, and it is possible to improve the accuracy of the degree of progress indicated by the site classification progress index.

Therefore, the "averaging" in the present embodiment includes not only the averaging of numerical values but also the averaging calculated by setting an upper limit value as described above (calculated by weighting described later). Includes the average).

Next, the phase progress rate is calculated from the site classification progress index (step S15). The phase progress rate is the progress rate (maximum 1.0) of the site classification progress index in the phase. Specifically, for example, in the first row (outer wall, position state) shown in FIG. 8, the site classification progress index is 223 and the target value is 225, which is before (lower) the target value 225 (in the current phase). ) When the target value of the phase is 200 (for example, when the current phase is phase 1, the target value is 225, and the target value of phase 0 of the previous phase is 200), the phase progress rate can be calculated from the following formula. ..

(Part classification progress index-target value of previous phase) / (target value of current phase-target value of previous phase) = (223-200) / (225-200) = 0.92
That is, the management method using the management system 1 is based on the target value corresponding to the current phase and the previous phase immediately before the current phase, and the site classification progress index corresponding to the current phase, up to the current phase. It has a progress rate calculation step in which a computer calculates a phase progress rate indicating the degree of progress.

FIG. 9 is an example of the calculation result of the phase progress rate, FIG. 9a shows a list of the phase progress rate in the phase 1, and FIG. 9b shows a graph of the phase progress rate in the phase 1. In this way, when the phase progress rate is calculated and the phase progress rate is confirmed in the phase progress rate list, phase progress rate graph, etc., even if different target values are set for each part classification in the same phase (phase of the outer wall). Even if the target value of 1 is set to 225 and the target value of phase 1 of the external door is set to 250), the phase progress rate for each part classification can be compared and confirmed at a glance.

Next, the progress rate (progress rate for each phase) of the BIM model 2a is calculated from the phase progress rate (step S16). Specifically, the progress rate of the BIM model 2a is calculated by averaging the phase progress rates for each part classification in the same phase. The progress rate of the BIM model 2a is calculated from the phase progress rate shown in FIG. 9a as follows (the progress rate of the BIM model 2a shown in FIG. 9a in phase 1 is as follows).

(0.92 + 0.72 + 0.58 + 0.97 + 0.75 + 0.88 + 0.82 + 0.91) / 8 = 0.82
That is, in the management method using the management system 1, the phase progress rate is calculated for each part classification, the phase progress rate for each part classification is averaged, and the progress rate of the BIM model 2a is calculated by the computer. It has a calculation step. It should be noted that the phase progress rate of the site classification may be treated in the same manner as in the above equation, but as shown in the rightmost column of FIG. 9a, a weighting item is set for each site classification and each site classification is set.

<Calculation of progress rate by extracting parameter input state>
Next, an example of calculating the progress rate of the BIM model 2a by extracting the parameter input state (extracting whether or not the parameter is confirmed) will be described with reference to the figure. FIG. 10 is an example of a flowchart from the extraction of the parameter input state to the calculation of the progress rate of the BIM model 2a.

First, the suitability for the conformity condition set in the parameter data 12c of the parameter (parameter set in the parameter data 12c) is extracted from the BIM model 2a (step S20).

That is, it is extracted whether or not the numerical values and characters for the parameters are fixed (correct input). That is, the management method using the management system 1 has an information extraction step in which the computer extracts information about whether or not the parameter is fixed. Such extraction may be performed automatically on a regular basis, or may be performed when confirming the progress of the extraction of the parameter input state.

Next, the parameter input state data 13b is created from the extracted data and saved (step S21). The parameter input state data 13b is the data shown in FIG. 4b.

Next, the ratio of the parameters that meet the conditions is calculated, and the phase progress rate is calculated (step S22). Here, the phase progress rate is calculated by a method different from the method for calculating the phase progress rate using the progress index described above.

Specifically, among the parameters, the ratio that meets the conditions is calculated from the number of parameters that meet the conditions and the number of parameters that are to be extracted, and the addition value to be added to the target value of the previous phase is calculated. The phase progress rate is calculated by calculating the cumulative value (corresponding to the site classification progress index when calculating the phase progress rate using the progress index) by adding the added value to the target value of.

That is, in the management method using the management system 1, the degree of progress up to the current phase is determined based on the target values corresponding to the current phase and the previous phase immediately before the current phase, and the information extraction result regarding the parameters. It has a progress rate calculation step in which a computer calculates the indicated phase progress rate for each part classification.

FIG. 11 is an example of the calculation result of the parameter ratio, the addition value, and the cumulative value that meet the conditions from the extraction result of the parameter input state, and FIG. 11a is an example of the calculation result of the parameter ratio that meets the conditions. , FIG. 11b is an example of the calculation result of the added value and the cumulative value.

As shown in FIG. 11a, since the number of parameters to be extracted differs depending on the part classification and the target value, the ratio of the input parameter is calculated for each part classification and the target value. Specifically, for example, at the target value 225 of the outer wall, the number of parameters to be extracted is 168, and the number of parameters that meet the conditions is 165. Therefore, the ratio of the parameters that meet the conditions is 165/168. = 0.98. Then, the ratio of the parameters that meet this condition can be regarded as the addition ratio (increase ratio) from the target value in the previous (lower) phase.

That is, the addition value can be calculated by multiplying the difference between the target value of the current phase and the target value of the previous phase by the addition ratio. As shown in FIG. 11b, for example, when the target value of the current phase of the outer wall is 225, the target value of the previous phase is 200, and the ratio of the parameters that meet the conditions is 0.98 (see FIG. 11a), so (225). -220) × 0.98 = 24 is the added value.

Then, the cumulative value can be calculated by adding the added value to the cumulative value of the previous phase (in FIG. 11b, the cumulative value of the row immediately above the current phase). As shown in FIG. 11b, for example, when the target value of the outer wall is 225, the target value of the previous phase is 200 and the cumulative value of the previous phase is 200, so 200 + 24 = 224 is the cumulative value.

Then, the phase progress rate can be calculated from the following formula from the target value of the current phase, the target value of the previous phase, and the cumulative value.

(Cumulative value-Target value of previous phase) / (Target value of current phase-Target value of previous phase) = (224-200) / (225-200) = 0.96
Then, the progress rate (progress rate for each phase) of the BIM model 2a is calculated from the parameter input progress rate (step S23). Since the calculation method is the same as that in step S16, the description thereof is omitted here.

<Calculation of progress rate of BIM model 2a>
As described above, as the phase progress rate of the same site classification (for example, outer wall), the phase progress rate using the progress index of the position state and the attribute state, and the phase progress rate using the information extraction result of the parameter input state. , Can be calculated. Then, the progress rate of the BIM model 2a can be calculated from each of the calculated phase progress rates, but the progress rate of the BIM model 2a can also be calculated after summarizing these phase progress rates.

FIG. 12 is an example of the calculation result of the phase progress rate, FIG. 12a is a diagram showing a list of the phase progress rates for each calculation source of the phase progress rate on the outer wall, and FIG. 12b is a diagram showing the phases for each calculation source. It is a figure which shows the phase progress rate for each part classification by collecting the progress rate into the phase progress rate of a part classification.

As shown in FIG. 12a, the phase progress rate of the outer wall can be calculated from the progress index of the position state, the progress index of the attribute state, and the parameter input state data. Then, these are averaged to obtain the phase progress rate of the outer wall. In FIG. 12a, (0.92 + 0.88 + 0.93) / 3 = 0.91. Here, although not shown in FIG. 12a, they may be weighted and averaged.

Then, as shown in FIG. 12b, the calculation of this phase progress rate is performed for the part classification (external door, external window, etc.) other than the outer wall, and the calculation result is used as the phase progress rate of each part classification. Then, the progress rate of the BIM model 2a is calculated from the phase progress rate by the same calculation method as in steps S16 and S23. Here, too, the progress rate of the BIM model 2a may be calculated by weighting as described in the rightmost column of FIG. 12b.

<About GUI>
In the present embodiment, the management method using the management system 1 described above is performed via the GUI (graphic user interface) displayed on the display unit 30 by activating the program on the computer. That is, for example, when an input program on a computer is started, a GUI for prompting an input person to input is displayed on the display unit 30, and the input person executes the above-mentioned management method by inputting to the GUI.

Hereinafter, as an example of the GUI, the GUI displaying the reification degree option and the approval stage option and the achievement rate of the BIM model 2a different from the progress rate of the BIM model 2a described above (a certain state index value for each part classification (FIG. 14). In FIG. 14, the achievement rate is simply described as LOD), and in FIG. 14, for example, a figure is used for a GUI displaying 82/100 = 82% achievement rate for the state index value 230 of the outer wall. I will explain.

FIG. 13 is an example of a GUI displaying the reification degree option and the approval stage option, FIGS. 13a and 13b are examples of the GUI displaying the selection by pull-down, and FIG. 13c shows the approval stage option of the confirmer. This is an example of a GUI that reflects ideas.

In the case of FIG. 13a, the input person selects the reification degree option from the pull-down menu and the approval stage option from the pull-down menu. In the attribute state of FIG. 13a, "determine basic classification" is selected as the materialization degree option, and "confirmer thinking" is selected as the approval stage option. By selecting by the input person in this way, the progress index is calculated and stored based on the degree of concreteness corresponding to "determine the basic classification" and the approval stage corresponding to "under consideration of the confirmer".

In the case of FIG. 13b, the degree of concreteness is selected from the pull-down menu, the corresponding degree of concreteness option is displayed, and the degree of concreteness option is selected. In the attribute state of FIG. 13b, the degree of concreteness “230” is selected, and the degree of concreteness option “determine basic classification” corresponding to the degree of concreteness is displayed. In other words, when the input person selects the degree of concreteness, the corresponding specific degree option "determine the basic classification" is presented, and it is confirmed that the input person has no problem (select the specific degree option). ). Since "confirmer thinking" is selected as the approval stage option, the progress index is calculated and saved based on the approval stage corresponding to the concreteness degree "230" and "confirmer thinking". ..

In the case of FIG. 13c, the input person selects the reification degree option in the same manner as in FIG. 13b, but the selection of the approval stage option reflects the ideas of a plurality of confirmers, and the ideas of the confirmers. Is configured so that the approver can consider. In the attribute information of FIG. 13c, the degree of concreteness “230” is selected and “determine basic classification” is selected as the degree of concreteness option, and “Good”, “Bad”, etc. The option of "Information" is presented, and the confirmers' thoughts on such option are "Good" 3 people, "Bad" 0 people, and "Neutral" 2 people. And, for example, in such a state, since all the ideas of the confirmer are not prepared, the confirmer is being considered as the approval stage option (in the case of such an approval stage option, the confirmed number of confirmers, The progress index can be changed even while the confirmer is thinking, depending on the type of selected option, etc. Also, when approving, the approver presses the approval button). Then, the progress index is calculated and stored based on the approval stage corresponding to the degree of concreteness "230" and "thinking about the confirmer".

FIG. 14 is an example of a GUI displaying the achievement rate of the BIM model 2a. As the achievement rate of the BIM model 2a, for example, as shown in FIG. 14, a list of stepwise state index values (200, 230, 250 ... In the figure) for each part classification is displayed, and further, at the right end. When the display button (display button at the right end of the external door in FIG. 14) is clicked, details such as the achievement rate of each state index value in the site classification are displayed.

<<< Effectiveness of management method using management system 1 >>>
As described above, in the present embodiment, a plurality of concreteness degree options in which the degree of concreteness of the parts of the BIM model 2a is represented by a level and a plurality of stages up to the approval of the degree of concreteness are represented in a staged approval stage. Based on the option presentation step presented by the computer, the selection acceptance step in which the computer accepts the selection from the presented reification degree options and approval stage options, and the selected reification degree and approval stage. , The progress index calculation step in which the computer calculates the progress index indicating how much the part is determined, and the association step in which the computer associates the calculated progress index with the part. Therefore, it is possible to improve the accuracy of grasping the progress of the parts in the BIM model 2a.

The BIM model can be viewed by a plurality of users and the progress can be confirmed, but its accuracy is unclear. For example, even if the position of the wall of the BIM model is awaiting approval and has not been decided yet (there is ample room for change), the information that it has not been decided is the head of the designer, approver, etc. It was only inside, and other users sometimes recognized that the position of the wall was fixed (the design was in progress until the position was decided).

On the other hand, in the present embodiment, the input person is made to select the concreteness degree option according to the concreteness degree of the part and the approval stage option according to the approval stage of the concreteness degree, and the progress index is selected from these two options. It was calculated and associated with the parts. Then, since the user of the BIM model 2a other than the input person can know the state of approval / disapproval of the part, for example, it is possible to suppress misunderstanding of the degree of progress of the part, and accurate information can be easily transmitted. That is, it is possible to improve the accuracy of grasping the progress of parts in the BIM model 2a.

Further, in the present embodiment, the parts belong to one of a plurality of types of site classifications, and the progress index associated with the parts belonging to the common site classification is averaged to determine the progress of the site classification for each site classification. It was decided to have a part classification progress index calculation step in which the index is calculated by a computer. Then, the progress can be confirmed by the part classification progress index for each part classification (outer wall, outer door, pillar, etc.).

Further, in the present embodiment, the site classification progress index is calculated for each of a plurality of phases (for each target value) of the project corresponding to the BIM model 2a, and the target value set for each of the plurality of phases is pre-registered. Based on the pre-registration acceptance step accepted by the computer, the target value corresponding to the current phase and the previous phase immediately before the current phase, and the site classification progress index corresponding to the current phase, the degree of progress up to the current phase is determined. It was decided to have a progress rate calculation step in which the indicated phase progress rate is calculated by a computer. Then, the phase progress rate in each phase can be confirmed.

Further, in the present embodiment, the phase progress rate is calculated for each part classification, and has a BIM model progress rate calculation step in which the computer calculates the progress rate of the BIM model 2a by averaging the phase progress rate for each part classification. I decided. Then, the progress rate of the BIM model can be confirmed.

Further, in the present embodiment, the target values are set for each of a plurality of phases of the project corresponding to the BIM model 2a and for each part classification of the BIM model 2a, and each of the target values is a parameter of the part classification. In the pre-registration acceptance step in which the computer accepts the pre-registration of the target value associated with, the information extraction step in which the computer extracts information about whether or not the parameter is fixed, and the current phase and the previous phase immediately before the current phase. Based on the corresponding target value and the information extraction result for the parameter, it is decided to have a progress rate calculation step in which the computer calculates the phase progress rate indicating the degree of progress up to the current phase for each part classification. Then, the phase progress rate in each phase can be confirmed from the information on whether or not the parameter is fixed.
