1 is a control block diagram of a building quantity calculation device according to an embodiment of the present invention.

As shown, the building quantity calculation device 1 according to the present embodiment includes a database unit 10, a BIM modeling module 20, a direct work item quantity calculation unit 30, an indirect work item quantity calculation unit 40, and It includes a quantity calculation unit 50. The building mass calculation device 1 may be implemented as a personal computer or a specialized computer used in the design process, and preferably has a storage capacity capable of storing a large amount of data. In addition, the building quantity calculating device 1 may be implemented as a portable terminal such as a telephone or a tablet PC, and may further include a user interface such as a display unit or a user manipulation unit (not shown). In addition, the building quantity calculating device 1 may further include a control unit (not shown) that controls communication between each component and controls input and output of necessary data, and a communication unit capable of receiving data from an external device.

The database unit 10 corresponds to a storage unit that stores construction drawing design information and data for selecting indirect work items necessary for calculating the construction quantity. The database unit 10 stores various data for BIM modeling, applications, and various data driven according to the operating device of the BIM modeling module 20. In addition, the indirect work item in the indirect work item quantity calculation unit 40 is stored. It stores the data needed to select. Various data stored in the database unit 10 may be deleted, changed, or added according to user manipulation.

The BIM modeling module 20 extracts work items and material information for elements including physical and functional characteristics of elements for each part of the building from the database unit 10, and extracts the work items and material information as attributes. To build a BIM model.

More specifically, the BIM modeling module 20 extracts information including a drawing number, a real name, a work site, a work item, and material information from a plurality of unit drawings to construct a construction drawing-based design information database. When such a construction drawing-based design information database is built, when a search term or search condition is input by a user, the BIM modeling module 20 works on elements corresponding to the search term or search condition from the architectural drawing-based design information database. Items and material information can be extracted, and a BIM object including extracted work items and material information as attributes can be configured.

2 is a view for explaining the elements and components according to an embodiment of the present invention, to clearly describe the terms used in the present invention.

As described above, the element is a concept corresponding to an object including physical and/or functional characteristics of elements for each part of a building, and includes information (materials, work items) extracted from 3D visual shapes and 2D drawing information. It can be configured as a base. In other words, the element may be defined as an object including physical (dimension) and functional (materials, heat permeability, etc.) characteristics for floors, walls, ceilings, pillars, beams, and stairs, which are elements for each part of the building.

For example, as illustrated in FIG. 2, the construction work performed on the wall may be selected as one element (wall element). Such one element may have a plurality of attribute information or attribute items indicating its characteristics, and in the case of wall elements, Project Name, ID, Floor, Room Name, Element Type, Thickness, Length, Height, Area, Element The material to be used can be attribute information.

Among such attribute information, numerical information such as thickness, length, height, and area may be used in the calculation formula for calculating the quantity of the work item directly in the direct work item quantity calculation unit 30. As shown, the volume of the wall element can be expressed as the product of the thickness and the area, where a numerical item can be used.

A component means a work item or material constituting an element, and for example, a construction work performed on a wall element can be divided into four items such as one type of liquid waterproofing, cement mortar, tile adhesive, and porcelain tile. A work item or a material used for a work item can be a component.

These components can be further divided into two items according to whether they are in the final stages of work, such as a representative item (representative component) and an accessory item (accessory component). The representative item may be a porcelain tile corresponding to Material 4 as shown as the final component of the element, and the representative item may be reflected in the name of the element (eg, 50 mm porcelain wall).

The sub-item refers to components other than the final component of the element, which corresponds to Material 1 to Material 3 in FIG. 2.

Returning to FIG. 1 again, the direct work item quantity calculating unit 30 according to the present embodiment extracts a component representing a work item or material constituting an element and attribute information of an element using a BIM model, and You can calculate the quantity. The direct work item means a work item that can be derived through attribute information and components of elements of the constructed BIM model.

The direct work item quantity calculating unit 30 extracts and stores attribute information such as height, length, circumference, area, etc. of elements from the BIM model, and also extracts and stores components of elements from representative items and sub-items reflected in the elements. have.

When the extracted information is calculated using a predetermined calculation equation, the quantity of water for each component can be calculated. For example, the area of the wall element may be calculated in the horizontal and vertical lengths of the porcelain tile, or in quantities required for the horizontal and vertical lengths of the porcelain tile. The calculation equation for calculating the quantity of water may be an equation already built through BIM modeling, and may be input and changed by the user as necessary.

The indirect work item quantity calculating unit 40 selects an indirect work item corresponding to a component not included in the element when it is necessary to calculate the quantity other than the element, and based on a relational expression for the indirect work item, the quantity for the indirect work item Can be calculated. The indirect work item quantity calculating unit 40 selects items that cannot be derived from the existing BIM model, that is, indirect work items other than elements or components that can be selected or calculated as the BIM model, and determines the quantity of the indirect work items. Calculate.

3 is a view for explaining an indirect work item according to an embodiment of the present invention.

As shown, four materials are used for the wall element, and work items for this, namely four direct work items, can be derived from the BIM model. On the other hand, in this wall element work, an indirect work item such as “corner waterproofing” that cannot be derived from the BIM model must be performed, and it is necessary to calculate the quantity and quotation for it.

That is, the indirect work item is a component not included in the element and is not reflected in the BIM model, but is necessarily included in the construction cost calculation statement. These indirect work items are not generally indicated in the 2D drawing and can be described in the corresponding construction (eg, waterproofing work) of the building specification.

The description of the indirect work item quantity calculating unit 40 will be described in detail with reference to FIGS. 4 to 6 below.

The quantity calculation unit 50 derives the quantity of materials required for each floor and room of the building and the construction cost based on the quantity calculated by the direct work item quantity calculation unit 30 and the indirect work item quantity calculation unit 40. Can.

According to the present embodiment, since the property information of the element includes the building's floor, room name, and the like as shown in FIG. 2, not only the calculation of the quantity for a specific element or component, but also the quantity for a specific floor or room Quantity calculation is possible. The user can derive the quantity for a specific space by inputting the conditions he or she wants.

4 is a control flow chart for explaining a method for calculating a building quantity according to an embodiment of the present invention.

As shown, first, the BIM modeling module 20 of the building quantity calculating device 1 includes a database unit 10 for work items and material information for elements including physical and functional characteristics of elements for each part of the building. And build a BIM model using work items and material information as attributes (410).

The BIM model is the most used model for estimating and calculating quantities in the current architecture and design. It contains information about work items or materials for elements and components that make up them, and provides attribute information for the characteristics of each component. It can be extracted from the BIM model.

The direct work item quantity calculating unit 30 extracts and stores attribute information and components of the elements from the BIM model in order to select work items directly related to the elements and components (420).

Liquid 1 type corresponding to Material 1 to Material 4 in FIG. 2, cement mortar, tile adhesive, and porcelain tile directly correspond to the work item, and attribute information on the wall element may be extracted.

Thereafter, the direct work item quantity calculating unit 30 may construct a component quantity calculation equation and store it (430 ).

The calculation formula for calculating the quantity of the direct work item can be derived from the attribute information of the component, and is configured to calculate the quantity of the required material based on the information about the unit material area and the area where the work is required.

If a direct work item is selected and an equation for calculating it is constructed, the building quantity calculating device 1 may determine whether it is necessary to calculate the quantity of the water for the elements other than the direct work item (440).

As a result of determination, if there is no additional element for calculating the quantity, the direct work item quantity calculating unit 30 calculates the quantity for the element, that is, the direct work item, by using the calculated equation (450).

The quantity calculation may include estimates of materials and construction costs, and estimates related to construction costs or work may be derived based on information on labor costs and other incidental costs required when performing the work.

The quantity calculation step 450 for the direct work item may be performed immediately after the configuration and storage step 430 for calculating the quantity for the component, or may be performed simultaneously or independently with the indirect work item selection step described below.

On the other hand, if it is determined that it is necessary to calculate the quantity other than the element, the indirect work item quantity calculating unit 40 selects an indirect work item corresponding to a component not included in the element (460), and is based on a relational expression for the indirect work item. By doing so, the quantity of the indirect work item can be calculated (470).

According to the present embodiment, the indirect work item quantity calculating unit 40 may select an indirect work item using data for a plurality of specifications and similar buildings for the building stored in the database unit 10. Details of indirect work item selection will be described in detail with reference to FIGS. 5 and 6 below.

Finally, when the calculation of the quantity for the direct work item and the indirect work item is completed, the quantity calculating unit 50 derives the quantity of material required for each floor and room of the building and the construction cost based on the calculated quantity, and the quantity A statement can be completed (480).

According to this embodiment, various versions of the quantity statement can be prepared according to the user's condition input, and for example, a quantity statement for each floor or specific room such as a bathroom or a work room may be derived.

5 is a control flowchart for explaining a method for selecting an indirect work item according to an embodiment of the present invention.

In order to calculate the quantity of the indirect work item, the indirect work item quantity calculating unit 40 may configure a spatial schedule as shown in Table 1 based on the spatial data among the attribute information of the element (510).

Table 1 shows the direct work items for floor finishing, ceiling finishing and wall finishing to construct the bathroom. Hereinafter, the element "BW01 reinforcing block stacking" for the wall finishing area marked in red, and the work item "reinforcing block stacking" in detail will be described as an example.

Thereafter, the indirect work item quantity calculating unit 40 may select an indirect work item by using a plurality of specifications and similar data for the building stored in the database unit 10 (520 to 560). .

The steps of selecting indirect work items using specifications (520, 530) and the steps of selecting indirect work items using data on similar buildings (540, 550, 560) are performed simultaneously and independently of each other as shown. It may be, or two steps may be performed sequentially according to a predetermined priority.

The indirect work item quantity calculating unit 40 may extract work items and materials for each type of work from the specification and analyze the association relationship between elements and work items (520).

Since the specification includes information on work items or materials by type that cannot be extracted from the BIM model, the indirect work item quantity calculating unit 40 extracts work items and materials by type using the specifications of multiple projects and relates them. By analyzing, and calculating the support items (Support), reliability (Confidence), and improvement (Lift) of the evaluation items of the related relationship, a masonry construction related relationship can be established as shown in FIG. 6.

FIG. 6 is a view for explaining the construction of an association using a specification according to an embodiment of the present invention. In FIG. 6, an association (a) of a masonry construction, an association (b) for a construction, and an element-work item The associations (c) for and the associations (d) for performance-site-work items are shown. Each relationship is built using support, reliability, and improvement, and if the relationship is high, the connection line becomes thicker, and if the relationship is low, the connection line can be expressed thinly.

When analyzing the relationship between the masonry construction and other construction types, it can be understood that the masonry construction is related to a number of construction types, elements, and work items, as shown in FIG.

In addition, masonry construction is associated with a number of other constructions, such as stone construction, window construction, reinforced concrete construction, mechanical construction, and metal construction, as shown in Fig. 6(b), especially stone construction, metal construction, reinforced concrete construction You can see that it is closely related to.

In addition, the indirect work item quantity calculating unit 40 may select an indirect work item through an association relationship between the analyzed element and the work item (530 ).

Figure 6 (c) is shown the relationship of the work items associated with the element called the concrete block, the indirect work item quantity calculating unit 40 derives the indirect work items through (c) of Figure 6, This can be reflected in Table 1. For example, the indirect work item quantity calculating unit 40 has five indirect works such as block mesh, reinforcing block construction reinforcing bar, strong anchor, cement mortar, metallas, and concrete through element-work item association (c). Items can be derived. Table 2 shows the derived indirect work items reflected in the spatial table of Table 1.

The indirect work item quantity calculating unit 40, which derives indirect work items through the specification, selects at least one building case similar to the building conditions of the current building through keyword matching for similar buildings, and the primary space table for each building case You can write (540).

The indirect work item quantity calculating unit 40 may use and search the database unit 10 to derive a case in which the project is in use and the same purpose. In other words, cases can be derived based on the purpose of the project overview, and more specifically, a list can be derived based on the keyword of'business facilities' by using the Metadata Library (MDL). MDL refers to data given to content according to certain rules in order to efficiently find information searched among a large amount of information.

Hereinafter, Table 3 shows similar projects searched through keyword matching for'business facilities'.

If only'business facilities' are simply matched in similar cases, two cases such as projects 18001 and 18004 are derived, but by using MDL to organize a group by forming a 1:n relationship with a representative word and similar words, the relationship with the ongoing project is deep. Three examples of projects 18001, 18002 and 18004 can be derived.

The indirect work item quantity calculating unit 40 may assign ranking scores in a similar order according to conditions such as coverage ratio, floor area ratio, floor number, construction period, and structure of the project outline for the three similar cases derived as described above. That is, if the project is quantified by items such as building coverage, floor area ratio, floor number, structure, and construction period for projects 18001, 18002, and 18004, and the ranking is given with the combined score, the project is given a ranking as shown in Table 4 below.

Thereafter, the indirect work item quantity calculating unit 40 may configure a primary space schedule for each construction case by selecting a predetermined number of construction cases having a high priority from the list in Table 4. The primary space schedule may be composed of a floor-room-site-element-work item type for each case, and may be configured in the same form as in Table 1.

The indirect work item quantity calculating unit 40 organizes work items for each part overlapped in the primary space schedule to derive indirect work items for a specific space or room, for example, to create a secondary space schedule. It can be (550).

At this time, after sorting based on a specific keyword, the redundancy of work items for each part can be checked. For example, if it is sorted based on the keyword'toilet', it is sorted by parts (floor, wall, ceiling), and then elements Duplicate check is performed based on the name, and duplicate elements can be excluded. Table 5 shows the second sympathy table prepared as an example.

The indirect work item quantity calculating unit 40 may select an indirect work item through the secondary space table thus prepared (560 ).

For example, through Table 5, the block mesh, the upper part of the block, the reinforcing bar for the reinforcement block, and the strong anchor can be set as indirect work items.

The indirect work item quantity calculating unit 40 selects a duplicate indirect work item as a main indirect work item among indirect work items (Table 2) selected from the specifications and indirect work items (Table 5) selected from the secondary space table. Can.

That is, the block mesh of Table 2, the rebar for reinforcing block construction, strong anchor, cement mortar, metallass, concrete, and the indirect work items of Table 5, the block mesh of the table 5, the top of the block, the reinforcement for reinforcing block construction, and strong anchor Through matching of work items, three work items such as overlapping block mesh, rebar for reinforcement block construction, and strong anchor can be selected as the main indirect work items. Table 6 is a reconstruction of the spatial table of the ongoing project by reflecting these three overlapping items.

At this time, whether to select a non-overlapping work item as the final indirect work item may be held once, or may be automatically selected or added by the user.

In accordance with the present embodiment, the indirect work item quantity calculating unit 40 determines whether to add indirect work items that do not overlap among the indirect work items selected from the specification and the indirect work items selected from the secondary space schedule. (580), can be selected as an additional indirect work item.

If the non-overlapping cement mortar, metallass, and block top dance are set to be automatically selected as additional indirect items, the indirect work item quantity calculating unit 40 includes this and finally selects indirect work items. Can (590).

At this time, the indirect work item volume calculating unit 40 may further perform a process of summing scores by applying a construction period weight, an application frequency weight, and the like in order to select an item related to the element (BW01 reinforcement block stacking). In this case, work items with a low score may not be selected from indirect work items and may be excluded.

On the other hand, if the indirect work item selected from the specification and the indirect work item not overlapping among the indirect work items selected from the secondary space schedule are not automatically added, the user may directly select it (585). At this time, the user can also select the indirect work items by referring to the combined scores by applying the weight of the construction period and the weight of the applied frequency.

If it is determined whether to add indirect work items that do not overlap, in addition to the indirect work items derived in duplicate through the specification and a similar project, the indirect work item selection by the indirect work item quantity calculating unit 40 is completed (590).

Table 7 shows a table of spaces reflecting three major indirect work items: block mesh, rebar for reinforcing block construction, strong anchor and additional indirect work items.

When the indirect work item is selected in this way, the indirect work item quantity calculating unit 40 can derive a relational expression using attribute information of the element extracted from the BIM model, and calculate and calculate the amount of the indirect work item using the relational expression. have. The relational expression for the indirect work item can be derived by utilizing the physical numerical information of the elements extracted from the BIM model, and an example of the relational expression is shown in Table 8.

As described above, according to this embodiment, by selecting indirect work items, efforts and time to increase the level of detail of the BIM model for accurate quantity calculation may be reduced. In addition, because it is possible to automate the calculation of the quantity at the work item level similar to the existing estimation method for the design proposal generated for each design stage, the user can directly review the cost. In addition, even if a change factor for the design proposal occurs, it is possible to actively cope with the calculation of the volume because it is possible to calculate the volume of the design proposal at the time of change.

In the process of design, it is possible to calculate real-time quantity without expert estimation knowledge, and through this, it is possible to help the user to make a reasonable decision by comparing alternatives for each design.

In addition, since it is possible to automate the calculation of the quantity using a different BIM object and parametric calculation formula at the design stage, it is possible to review and adjust the construction cost calculated for each alternative through linkage with unit price information in the future.

7 is a control block diagram of a building quantity calculating device according to another embodiment of the present invention.

As illustrated, the building quantity calculating device according to the present embodiment may include a user terminal 100 and an artificial intelligence (AI) server 200 that can communicate with the user terminal 100.

The user terminal 100 includes a database unit 10, a BIM modeling module 20, a work item quantity calculation unit 35, and a quantity calculation unit 50, which is very similar to the building quantity calculation device of FIG. It has a composition. Description of the overlapping configuration is omitted.

The user terminal 100 according to the present embodiment may be implemented as a phone or a portable computer that the user can carry, and may be implemented as various devices used in a construction site. The user terminal 100 may further include a user manipulation unit and a display unit capable of displaying information extracted from the BIM model. In addition, the user terminal 100 may further include a communication unit (not shown) that can communicate with the AI server 200 by wire or wireless.

The work item quantity calculating unit 35 extracts attribute information and components of the element using the BIM model, calculates the quantity of the component, and calculates the quantity of the indirect work item selected through the AI server 200. That is, according to the present embodiment, the indirect work item may be selected from the external AI server 200, the work item quantity calculating unit 35 receives information on the selected indirect work item, and the attribute information of the BIM model Calculate the quantity using. Contents for calculating the quantity of work items are different from those performed in the direct work item quantity calculation unit 30 and the indirect work item quantity calculation unit 40 of FIG. 1.

Meanwhile, the AI server 200 may store data related to the indirect work item, and select an indirect work item through learning about the indirect work item when it is necessary to calculate the amount of quantity other than the element. To this end, the AI server 200 may learn indirect work items using data for a plurality of specifications or similar buildings for the stored building.

The AI server 200 stores various algorithms capable of performing mechanical learning based on big data, collects a large amount of information extracted from construction documents related to Internet networks or various buildings, and indirectly based on the collected information. You can update your learning about work items.

In the case of selecting an indirect work item using a knowledge base constructed through examples and rules to calculate the building quantity, in particular, the computational throughput of the user terminal 100 for deriving the indirect work item can be reduced and indirect Work items can be selected more accurately and quickly.
