That is, Figure 1 is a system diagram for explaining the construction information processing method combining the cost / schedule / space system according to the present invention.

As shown in FIG. 1, the system of the present invention includes a computer device 100 connected to a keyboard 102 and a position coordinate input device 106, and the computer device 100 includes an input unit 2 and a cost. Item extraction unit 4, work classification application processing unit 6, quantity calculation unit 8, cost element extraction unit 10, common and process management element generation unit 12, common and process management element linked processing unit (14), the information database 16, the keyboard interface 104, and the position coordinate interface 108. As shown in FIG.

In the computer device 100 of the figure, the input unit 2 receives the cost data, the model data, and the spatial data for a predetermined building and construction item, and the cost, the model, and the spatial data are received from the CAD system. It is also possible to use the data generated in the process of extracting the shape and location information for quantity calculation from the created two-dimensional or three-dimensional CAD data, which is input as basic data information on the building and construction items by the user's input. It is also possible.

Here, in the cost data, the type data, and the spatial data, cost hierarchy of the cost data is generated by a person who calculates the quantity and estimates the cost for a predetermined building and construction item. As the abstracted classification information used, it corresponds to the classification criteria for preparing a statement, and a cost classification structure (CBS) is generated in combination with the spatial classification by the spatial data.

In addition, the Work Hierarchy of the work data is abstracted classification information used by the person in charge of planning and managing the work. The work hierarchy is used to define the scope of each work constituting the work and to define the predecessor relationship between the work. A co-classification structure (WBS) is used in combination with the spatial classification by the spatial data.

In addition, the space classification based on the spatial data is a hierarchical classification system for a space commonly used in a cost classification structure and a co-classification structure, and includes a definition of a reference plane of a space. The hierarchical levels used in the and taxonomy structures may be different.

In the figure, the cost item extraction unit 4 extracts the cost item as the lowest element of the cost calculation for the quantity calculation from the cost data from the input unit 2, where the cost item of the quantity calculation is generated. Cost classification is inherent from this point in time.

The work classification application processing unit 6 applies the work classification for each cost item by analyzing the type of work performed on the cost item in the corresponding building and construction work. The application process is performed artificially by manual operation in accordance with user operations of the keyboard 102 and the position coordinate input device 106.

The quantity calculating unit 8 is included in a reference plane (for example, an indoor plane repeated for each lake for each floor in an apartment construction), which is repeated in the building and construction items based on the quantity calculation information of the information database 16. The quantity of each cost item will be calculated.

The cost element extracting unit 10 applies the cost item data for each reference plane whose quantity is calculated by the quantity calculating unit 8 to the spatial classification based on the table information of the information database 16. As individual cost items are individualized, work elements applied to such specific spaces are extracted as cost elements.

Here, the spatial classification table 18 of the information database 16 contains information of a reference plane that holds quantity calculation data for each cost item, and the cost element extraction unit 10 includes the spatial classification table 18. Based on the reference plane information, the cost calculation data for each cost item can be distributed according to the space classification. As shown in Table 1 below, the data can be processed by the SQL command by the expression between the data tables.

 INSERT INTO [cost element] SELECT [spatial classification] .spatial classification code, [reference plane] .cost item code, [reference plane] .volume FROM [spatial classification] INNER JOIN [reference plane] ON [spatial classification] .reference plane Code = [reference plane]. Reference plane code;

However, in the SQL command of Table 1, the "cost element" is a table containing cost items individualized for each space, and the information database 16 is based on the information of the cost elements individualized by the cost element extractor 10. The cost element table 20 is created.

The common and process management element generating unit 12 applies a common classification applied by the industrial classification applying processing unit 6 to the data of the individualized cost items for each space in the cost element table 20, thereby providing a common classification item. By converting to, the work elements with spatial classification applied to these work items are created as common denominators. In this case, the common people do not include the contents of the process control elements. ) To be the final common (final common) by the following method.

That is, the common and process management element generation unit 12 is determined according to the operation order of the detection and construction work according to the input operation by the keyboard 102 and the position coordinate input device 106 of the process planning and management personnel The specific spatial classification level and the type classification level are determined to generate a process management element table 24 containing process management elements, and a process table is created accordingly.

The common and process management element linkage processing unit 14 has the same space classification and work classification as the process management element of the process management element table 24 from the common person (intermediate common person) of the common table 22. The commons (final commons) database is created by extracting commons (intermediate commons) and linking them to each other.A person in charge of building and construction works on the construction by using the commons (final commons) database. It will be able to carry out the process planning and management of the construction and apply it to the post quality control after the completion.

Here, the common person (the last common person) is common to the reference plane by the work classification applied through the work classification application processing unit 6 for the quantity calculation data for each reference plane cost item of the spatial classification table 18. A classification calculation table is generated, and it is preferable that the cost element extraction unit 10 can generate and generate the cost elements of the common classification calculation table.

On the other hand, the common person (final common person) in the state in which the quantity calculation for each cost item of the reference plane is made in the quantity calculation unit 8 with respect to the cost item, the spatial classification table 18 containing the quantity calculation data is generated After the individualization of the cost elements of the reference plane cost item by the cost element extraction unit 10 is performed, the associated work classification values may be associated with each other by the work classification application processing unit 6 so as to be generated. It is.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowcharts of FIGS. 2 and 3.

First, the cost item extraction unit 4 of the computer device 100 extracts the cost item as an item of cost calculation for quantity calculation, for the cost data for a predetermined building and construction item received through the input unit 2. As such, such cost items are inherent in the cost classification from the time of their occurrence (step S10).

In this state, in the work classification application processing section 6, in accordance with an operation using the keyboard 102 and the position coordinate input device 106 of the person in charge, each cost item extracted from the cost item extracting section 4 is of some kind. Analyzing whether the work is performed by work (ie, work classification) and applying work classification to each cost item, the relationship between cost items and work classification is treated as "M: 1" or "1: N". (S11). The cost classification and the work classification are generated with a classification item of the minimum unit which is no longer divided, which is usually formed by the relationship of "M: 1", except for "1: N". May exist. That is, in the case where the cost classification and the work classification are "M: 1", if one work classification is, for example, "light partition wall installation", a number of cost items required for the "light partition wall installation" (eg, painting) , Cement, brick, etc.). In the case where the relationship between the cost items and the work classification is "M: 1", a single work classification may be applied to a plurality of cost items, but specifically, In the case where the relationship of work classification is established as "1: N", the work should be divided into work having at least two work classifications for one cost item. The manual classification is applied by dividing by manual hand. After such work classification, a classification item having both cost classification and work classification is created, which is a common classification item (step S11).

In addition, the quantity calculating section 8 extracts the cost items to be input to the reference plane that is repeated in the same building and construction items on the basis of the quantity calculating information of the information database 16, and calculates the quantity of the cost items. It calculates and stores the quantity calculation data for each cost item in the reference plane information of the space classification table 18 (step S12).

On the other hand, the cost element extraction unit 10 by individualizing the cost items by space classification based on the reference plane information of the quantity calculation data for each cost item stored in the space classification table 18 of the information database 16, Cost elements are extracted as concrete work elements. That is, when the cost item is, for example, "painting", by applying the concept of spatial classification, for example, by individualizing it into "type A wall", cost elements such as "painting of type A wall surface" are extracted. The data of the cost elements generates the cost element table 20 of the information database 16 (step S13).

In this case, the common and process management element generation unit 12 converts the cost item into a common classification item by applying a coarse classification to the cost items for each spatial classification, which are individualized by the cost element extraction unit 10, The work factor, that is, the common factor (intermediate common part), which is applied to the spatial classification and the work item at the same time, is generated and stored in the common table 22 of the information database 16. Step by step has a hierarchical structure, and the lowest hierarchical items of each classification are correlated (step S14). This is to create a common (intermediate common) by the method shown as option 1 in FIG. Another method of generating a common person (intermediate common person) is to first apply the cost item of the item cost data calculated by the item cost calculation unit 8, as shown by option 2 in FIG. )on The method of changing the generated common classification item to generate a table of quantity calculation for each common classification of the reference plane by applying the work classification, and to generate the common person (intermediate common person) by individualizing the cost items of the quantity calculation table of the common classification. As described above, the commons (intermediate commons) generated by the method of option 1 or option 2 shown in FIG. 2 are intermediate stages of common who do not yet have process management related information.

In addition, in accordance with the creation of the common person (intermediate common person), the spatial classification level and the work classification level are determined in accordance with the input operation of the keyboard 102 and the position coordinate input device 106 by the corresponding process planner and manager. The determined process management element is extracted to generate the process management element table 24 (step S16).

Next, the common and process management element linkage processor 14 combines the process management element table 24 with the space classification and the work classification in the common (intermediate common) of the common table 22. By extracting the commons (intermediate commons) of the same classification combination as the elements, and associating the extracted commons (intermediate commons) with the process control elements, the commons (final commons) database is created. (Step S17).

On the other hand, the operation of the common and the process management element linkage processing unit 14 in the common and process management element linkage processing unit 14 will be described in more detail through the flowchart shown in FIG.

First, the common and process management element linkage processing unit 14 is moved to the first record of the process management element table 24 of the information database 16 (step S20), and the code of the process management element on the first record. Data is extracted (step S21).

In this state, the spatial classification value and the work classification value of the process management element are respectively extracted (step S22), and the spatial classification value of the common in the common table 22 is the same as the spatial classification value of the process management element. Compares the common classification of the process control element with the same common classification value, and finds a common person with the same value as the process control element containing the same spatial classification value and the common classification value. The common list is extracted (step S23).

On the other hand, the common and process management element linkage processing unit 14 applies the process management element code of the process management element table 24 to the extracted common list (step S24), the record of the process management element is It is judged whether or not it is the last record (step S25).

As a result of the determination, when it is determined that the code of the process management element is not the last record, the common and process management element linkage processor 14 moves to the next record of the process management element table 24 (step S26) Then, the operations of steps S21 to S24 are repeatedly executed in the state in which the process management element code data of the next record is extracted.

On the other hand, when the common and process management element linkage processing unit 14 completes the linkage process between the common and the process control element, a common (final common) database is finally built to the construction of the building and construction items It can be used for process planning and construction management, and it can be widely used for quality control that is performed after completion of building and construction work.

It is a matter of course that the present invention having the above-described embodiments can be variously modified and implemented without departing from the gist of the present invention without departing from the gist thereof.

As described above, according to the present invention, a common person that can be widely used for future quality control as well as process planning and construction management by combining space classification, cost classification and industrial classification for a predetermined construction and construction work (final common) I) As the database can be built, accurate data on cost and work elements can be included in the schedule.
