On the other hand, Figure 7 is a flow chart illustrating a step-by-step document creation method according to an embodiment of the present invention.

Before describing an embodiment of the present invention with reference to the drawings, some terms used below are defined.

First, the 'volume table' is a table calculated as a result of 3D modeling and includes quantity information, unit price information, and time information of each modeling object. The quantity information, unit price information, and time information of the objects included in the quantity table are designated for each object in the three-dimensional modeling, process order, etc., and the information on the tasks and resources required for each method is matched. It can be calculated automatically.

In addition, ‘industry’ is used as a term meaning a construction item that is a breakdown of the construction process.

In addition, the following 'classification code' is to express various types of information about each object included in the quantity table according to a standardized classification scheme and compress them into a string of predetermined digits, each object as defined in the standard setting table to be described later Is given to.

'Standard setting table' is a table that defines the classification code to be assigned to each object included in the quantity table, and can be selected as a value for each item for a plurality of items inputted for each object in the quantity table. A table preset by encoding various options.

And 'Animal volume' means information about the quantity (quantity, length, width, volume, etc.) automatically calculated for each modeling object by 3D modeling, and 'Animal quantity' is the quantity calculated automatically. The information on the quantity calculated by the calculation according to the 'aquatic animal quantity' is the information about the quantity manually input by the designer or the builder according to the experience, such as can not be calculated automatically or by a simple operation as described above.

In addition, the 'Quantity Report' is a statement on the quantity of materials required by construction, by tool, and by business unit, and it is a document that presents the basis of calculation for each quantity based on the design data.

On the other hand, the 'design budget' is a statement of the material costs, labor costs, and expenses required for the construction.

The construction quantity calculation system 100 according to an embodiment of the present invention described by FIG. 1 may be implemented as an information processing apparatus such as one or more computers. Here, the computer may include, for example, a desktop, a laptop, and the like.

The construction quantity calculation system 100 according to an embodiment of the present invention includes a modeling unit 10. The modeling unit 10 is a means for receiving a command or data from a designer to design an object of an architectural or civil construction work in three-dimensional graphics. In this case, the designer may proceed with the 3D design based on the 2D modeling drawing using the modeling unit 10 as needed.

In the three-dimensional design using the modeling unit 10, as shown in FIG. 3, a name for the three-dimensional object, a work type for constructing the object, and the like may be selected. Can be set. In addition, the unit cost of the material required to build each object may be set together. That is, quantity information, time information, unit price information, etc. of the object may all be set.

On the other hand, the construction quantity calculation system 100 according to an embodiment of the present invention in the automatic quantity calculation unit 20 for automatically calculating the quantity of the object based on the quantity information, time information, unit price information set for the object as described above May be included.

The automatic quantity calculating unit 20 may match the quantity data of the object, the type of the quantity data (length, width, volume, weight, etc.) and unit information corresponding thereto based on the selected work type for the object.

Accordingly, the automatic quantity calculation unit 20 generates a quantity table including construction information such as quantity information, time information, and unit price information for each object. In this case, the quantity table may be configured as a spreadsheet type file including a plurality of items of construction information for each independent object, for example, an Excel file on Microsoft.

In this case, the automatic quantity calculation unit 20 may be formed of the modeling unit 10 and one configuration (for example, a program executed in a computer), or may be separate components linked to each other. In addition, the automatic quantity calculation unit 20 may be configured as an add-on program for the modeling unit 10.

Here, a form of the quantity table created by the automatic quantity calculating unit 20 will be described by way of example. As shown in FIG. 3, each cell of the first column describes the name of each object, and In the cell, the construction information for each object is divided into a plurality of items (large classification, middle classification, small classification, etc.), and in each row, the construction information corresponding to the object described in the left cell is listed by item. The values of each object for the item listed in each cell of the first row are listed.

In this case, a plurality of items for construction information described in each cell of the first row will be described below as 'fields', and an item selected as a value for each field is called a 'field value', and one field will be described. One or more selectable options are described as 'parameters'. For example, the parameters of the large classification field may be three types of 'tunnel', 'road', and 'bridge'. As such, the number and type of parameters that may be determined as field values of the corresponding field may be determined according to the characteristics of each field.

Here, the types of fields may be further illustrated by classifying tools, classifying tunnels / bridges / roads, ordering objects in the case of several homogeneous objects in the same tool, type of object cross section, direction of construction progress for each tool, starting point and end point. It may include code for the classification of, and may further include the quantity (unit, number, length, area, volume, etc.) automatically calculated by the modeling, a premium specified by the designer during modeling or a preset premium rate according to the type of work. have.

On the other hand, the construction quantity calculation system 100 according to an embodiment of the present invention includes a code matching unit 30 for writing the classification code in the quantity table created by the automatic quantity calculation unit 20. Code generation unit 30 generates a classification code that adds a 'classification code' field to the quantity table generated by the automatic quantity calculation unit 20 and generates and writes a classification code as a field value for the corresponding field. It includes a unit 31 and optionally includes an error detection unit 33 to be described later.

At this time, the classification code generation unit 31 of the code matching unit 30 compares each field value described in the plurality of fields for each object with the parameters described in the preset standard setting table, and compares the field value with the corresponding parameter value. The individual codes matched to the parameters are converted, and the converted codes are arranged at preset positions to generate classification codes.

In this case, the classification code will be described as one specific example. As shown in FIG. 4, the classification code includes a character string having a predetermined number of digits. In each position, the types of parameters to be arranged are predetermined. At this time, as described above, each parameter type corresponds to each field. That is, for example, an individual code corresponding to any one parameter of a tunnel, a bridge, and a road is arranged in the first digit of the classification code, and the corresponding field may be a 'major classification' field of the quantity table.

As illustrated in FIG. 4, the classification code may be predetermined to include a total of 26 digits, and the first five digits may correspond to the major classification, the middle classification, the small classification, the subdivision, and the subdivision according to the classification system of the current Ministry of Land, Transport and Maritime Affairs. The next five digits are arranged in the code of the Ministry of Land, Transport and Maritime Affairs, for each additional category with each field unspecified, followed by five digits, six digits, and again five digits. It may correspond to each field that can be specified according to the input value in the dimensional modeling. For example, codes corresponding to tool information, an arrangement order of each object, a quantity calculation method, an orientation or a location of an object, a process order, and the like may be sequentially arranged at one or more consecutive positions. However, what is shown in the drawings is only one example, and the format and the number of digits of the classification code may be determined differently from those illustrated.

In addition, as illustrated in FIG. 5, parameters that can be input as field values are listed in the standard setting table, and individual codes corresponding to respective parameters listed are defined. For example, a total of three parameters that can be selected as field values in a large classification field are tunnels, roads, and bridges, and N, L, and K may be matched to the tunnels, roads, and bridges as individual codes, respectively.

In another example, as a subclass of a large category field tunnel, the blasting, TBM, shield, and other processes of the excavation work are input as parameters, respectively, and corresponding individual codes A, B, C, and D are assigned to the middle category field. Can be.

Accordingly, the process of generating the classification code for the first object (model name 'support pattern P-3 extension') described in the quantity table shown in FIG. 3 will be described briefly. The individual code defined in the standard setting table for the field value 'tunnel' is 'N', which is arranged in the first digit designated as the individual code for the major category field. The remaining digits of the classification code are thus determined.

Here, the classification code generation unit 31 may also play a role of notifying the user of missing or coming data found while generating and writing the classification code. For example, a field that does not contain a null value in a parameter, for example, a field value is not described in a major category field, or 'E' is a field value of a field in which only A, B, C, and D are defined as parameters. If there is a missing or coming out of the field value required for generating the classification code, such as described, it can be detected and inform the user of the location. Accordingly, the user can directly modify the quantity table or correct errors in the 3D modeling process. Again, the volume table can be automatically calculated.

In addition, the error detection unit 33, which may be included in the code matching unit 30, generates each classification code and writes it as a field value in the classification code field, and then the classification codes overlapping each other among the classification codes included in the quantity data field. Check whether a value has been entered. Even if the same kind of object has different tools, process order, arrangement position, etc., the classification codes should not overlap with each other. Even though each classification code should be a unique value, the classification codes may be duplicated due to errors or duplication of data. In this case, the error detector 33 may detect the duplication of the classification code and display the location of the corresponding object to the user.

In addition, the error detector 33 may compare the first quantity table and the second quantity table and search for one or more cells including different field values. This is to compare the original quantity table (for example, the quantity table created by the designer) with the quantity table used by the contractor later, to check whether the work was made and the quantity was calculated without any design change or quantity manipulation. It is an additional feature.

At this time, the code matching unit 30 is a configuration that can load the quantity table, read, process and edit the information contained in the quantity table, for example, a program that is compatible with the spreadsheet type file such as the Excel file. This can be Accordingly, it should be able to retrieve and process the file of the format created by the automatic quantity calculation unit 20, fill in a new field, and find the location of the error and display it to the user. Therefore, the code matching unit 30 may be configured to be compatible with one or more programs of the spreadsheet type.

In addition, in one embodiment of the present invention, the additional quantity calculation unit 40 may be provided. Additional quantity calculation unit 40, in addition to the quantity calculated by the automatic quantity calculation unit 20, the animal quantity calculation unit for calculating the amount of soft animals calculated by calculating one or more automatic quantity automatically calculated according to a predetermined function ( 41) and aquatic animal quantity calculation unit 43 input by a user such as a designer. Each field value and function for calculating the amount of soft animals may be predefined in the soft amount calculating unit 41.

In this case, the additional quantity calculation unit 40 may be formed in an independent configuration, but may be formed in the same configuration as the automatic quantity calculation unit 20 or in the same configuration as the code matching unit 30. Accordingly, the amount of soft animals or the amount of aquatic animals may be added to the quantity table in the automatic quantity calculation unit 20 before the classification code is assigned, or may be added to the quantity table in the code matching unit 30 after error detection is completed after the classification code is assigned.

In addition, the error detector 33 may detect an error included in the quantity table together with the amount of soft animals or the amount of animals added in this way.

On the other hand, the construction quantity calculation system 100 according to an embodiment of the present invention may further include a document generation unit 50. The document generation unit 50 is configured to generate a document including a result of calculating the quantity or amount of materials to be used in construction by using a quantity table to which a classification code is assigned. For example, the document generation unit 50 may include a quantity calculation generation unit 51 for generating a quantity calculation and a design budget generation unit 53 for generating a design budget.

In the document generation unit 50, a plurality of different templates may be predefined in accordance with the type of each document and the range of contents to be included in each document. For example, the document generation unit 50 may be predefined templates that are separated from each other according to the characteristics of the object, in advance to store a different quantity calculation template for each bridge, road, tunnel, and one of them from the user You can choose to write a document.

The quantity calculation template may include, for example, an object for calculating the amount of money and a standard, unit, quantity, unit price, amount of money, a calculation basis, etc. corresponding to the object. At this time, for example, if the object of calculating the amount of the quantity statement is all bridges included in the first tool, the individual code value of the place indicating the tool of the classification code is '1' among all the classification codes included in the quantity table. After extracting all classification codes, only the classification code whose first digit of the classification code is 'K' representing the bridge is extracted, and the quantity of each object corresponding to the extracted classification code is multiplied by the unit price and summed. The calculation process may be automatically filled in as a calculation basis.

For this purpose, an individual code or a whole classification code to be included in each item to be written in the quantity statement, or to be included in the operation for each item may be defined, and a function for the operation may be defined together. And this may be predefined in the template or set by the user.

At this time, the document generation unit 50 searches for a classification code not used for preparing a quantity statement or a design budget in the quantity table corresponding to the quantity statement or the design budget when the quantity statement or the design budget is generated. This is because the classification codes not used in the quantity statement or the design budget mean that some of the items required for the actual construction are missing.

Hereinafter, the construction quantity calculation method using the construction quantity calculation system 100 according to an embodiment of the present invention as described above will be described step by step.

As shown in FIG. 6, the method for calculating a construction quantity according to an embodiment of the present invention begins with a step S100 of performing three-dimensional modeling. In this step, a work type, a process order, or the like for each modeling object may be designated as described above.

When the 3D modeling is completed, quantity information is automatically calculated based on the information about each modeled object, and a quantity table for various types of information including the calculated quantity information is created (S200). In this case, the quantity table may be prepared by a function provided in the 3D modeling program as described above, or may be prepared by a separate add-on program or the like.

Subsequently, based on the created quantity table, a classification code corresponding to each object included in the quantity table is generated and matched (S300). At this time, the classification code is prepared based on the field value corresponding to each field for each object. For this purpose, the step of creating a standard setting table may be preceded. As described above, the standard setting table includes information on one or more parameters that can be input in each field and individual codes corresponding to each parameter.

If a classification code is assigned to each object of the quantity table, an operation of detecting an error may be additionally performed by performing a redundancy check whether there is a duplicate classification code among the given classification codes.

Accordingly, if duplicate classification codes are detected, their location can be displayed to the user to correct the error. If the error is corrected again, the same process may be performed again by repeating the step S310 until no classification code is detected.

When the process of assigning a classification code to the quantity table including only the automatically calculated quantity information and correcting the error is completed, the step of calculating and writing the quantity of the animal and the quantity of the animal can be performed based on that.

In this case, the amount of soft animals may be calculated by defining a function using some of the automatic quantity as variables, and the amount of water animals may be calculated by simply inputting from a user.

When all the quantity information is completed, the process of assigning a classification code is repeated again (S500), and then, once again, whether there is a duplicate classification code (S510), the process of minimizing an error is repeated.

Accordingly, when the process of assigning the classification code to all the objects of the quantity table is completed, a step of automatically generating a document related to the quantity of construction such as a quantity calculation statement or a design budget using the assigned classification code may be performed (S600). .

Meanwhile, as illustrated in FIG. 7, the step of generating the document illustrated in FIG. 6 is described in more detail. First, a step S610 of selecting a quantity table to be used when generating the document is performed. The quantity table selected here should be assigned a classification code and have completed error correction.

When the quantity table is selected, a template to be created is selected using the selected quantity table (S620). In this case, one or more selectable templates may be provided so that a user may search for and use a required template.

Each template is basically set with various calculation items and information to be included in the document. A function to be used together with information on a classification code or an individual code related to information to be written in each basic calculation item may be set. That is, for example, when the material cost of all the materials to be used for the first tool is set as the calculation item, the classification code including the individual code corresponding to the first tool in the quantity table by setting the 'first tool' as the item Are extracted, and each material information (material type, standard, etc.) corresponding to all extracted classification codes is automatically filled in, and corresponding quantities are summed and displayed.

Of course, if there are some items to be modified in the template, the user may directly set the corresponding parts (S630).

When the template selection and setting is completed, a step (S640) of calculating a value corresponding to the set calculation item is performed. For example, when the labor cost required for road construction is determined as a calculation item, after extracting all the classification codes in which the individual codes corresponding to the large classification fields are set to 'L' from the classification codes included in the quantity table, the extracted classification codes and According to the type and quantity defined in the corresponding quantity information, multiply the preset unit labor costs and add up each item to calculate the labor costs and fill in the document.

At this time, in step S640, the calculation basis is automatically generated for each calculation item, and the quantity information corresponding to the classification code used for the calculation of the value corresponding to the calculation item and the function for calculating them can be automatically written in the calculation basis. have.

When the document is generated according to the above process, and all the documents are created for one quantity table, the step (S650) of extracting the classification code not used for document creation may be performed. Through this, you can check the missing quantity and make more accurate cost forecast. Here, the document generation may be performed by creating a plurality of documents based on one quantity table, generating a single document by summing up the plurality of created documents, and extracting an unused classification code. This can be done after the preparation of all documents to be prepared using the quantity table.

When the unused classification code is extracted, it provides the user with what is the unused classification code (S650). In this case, when two or more unused classification codes are extracted, the common classification of the extracted classification codes may be detected and notified to the user. For example, in a construction involving a process for all tunnels, bridges, and roads, a plurality of unused classification codes are extracted after document generation, and all of the extracted classification codes include N, where the first digit represents a tunnel. For example, a user may be notified that the quantity for the tunnel is missing from the quantity statement or the design budget.

That is, it is possible to detect values common to each other in the extracted unused classification code and to suggest to the user that a corresponding parameter is missing from the calculation.

By extracting the unused classification code as described above and informing the user, the document is induced to be generated without a missing quantity, and then a document is generated by automatically writing the calculated value in each calculation item of the selected template (S660).

The document generation may be completed by outputting the generated document (S670).

The construction quantity calculation method according to the embodiments described with reference to FIGS. 6 and 7 may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by the computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be.
