In modern construction, accurate quantity and cost according to quantity calculation are important factors that determine the success or failure of a construction project.

BIM (Building Information Modeling) refers to a 3D design technology that has recently become a hot topic in the construction industry.

There are differences between 3D drawings of buildings using BIM and BIM (3D) quantity information, which is quantity information based on the 3D drawings, and 2D quantity information, which is quantity information based on 2D drawings calculated according to predetermined standards, so it is applied to actual construction sites. It is difficult to do,

The problem of comparing and verifying each other has been pointed out because the calculation basis is not clearly exposed.

In addition, 2D-based quantity calculation, which relies on existing manual work, results in very different quantity calculations depending on the operator's mistakes or the level of know-how of the estimator, and most of the work has to be performed again every time the design is changed, which is a problem of wasting manpower and money. The downside is that it is difficult to verify quantity except for quantity calculation experts.

Accordingly, the present inventor proposes a BIM (3D) drawing of a building, which is used in construction work, BIM (3D) quantity information based on the BIM (3D) drawing, and quantity information based on a 2D drawing calculated according to a predetermined standard. This is to solve the problem that it was difficult to compare and verify the 2D quantity information because not only were there differences between them, but the calculation basis was not clearly exposed.

Ⅰ. 2D drawing-based visualization and management system of quantity and calculation basis

The 2D drawing-based quantity and calculation basis visualization and management system of the present invention is performed in a dedicated application including a computer program mounted on the user's computer or user terminal, including a smartphone, connected to a server by online communication means including the Internet.

Receive the BIM (3D) drawing of the building and the BIM (3D) quantity information based on the BIM (3D) drawing,

Based on this, create a 2D drawing and 2D quantity information, which is new quantity information based on the 2D drawing,

It is characterized in that the BIM (3D) quantity information and the 2D quantity information and calculation basis can be compared and evaluated.

The dedicated application above is,

Detect errors in the BIM (3D) drawing, including overlapping or missing parts between members,

Because it is displayed on the 2D drawing,

The user can intuitively check and modify this with the naked eye using the dedicated application to create a modified 2D drawing.

The above-mentioned error part is, for example, a case where two beams overlap each other and the quantity is calculated in duplicate, or when the quantity is omitted because there is a part where concrete is not poured.

The 2D quantity information is characterized in that it is modified in real time in conjunction with the revised 2D drawing,

The dedicated application above is,

It is characterized by displaying the differences between the BIM (3D) quantity information and the 2D quantity information for each item.

The present invention creates 2D drawings such as floor plans, elevation views, and cross-sectional views from BIM (3D) drawings of buildings.

Taking the plan view as an example as shown in Figure 2,

In the 2D drawing, 'member-specific information' such as the amount of concrete, amount of rebar, and amount of form is matched to each structural member such as columns, beams, and slabs, and 'finishing for each room' such as mortar, paint, and wallpaper used as finishing materials for each space. ‘Information’ is matched.

This matched information is created and managed by the user as ‘2D quantity information’ using a dedicated application.

The 2D quantity information may be operated while mounted on the 2D drawing, but may be managed separately to increase the capacity and processing speed of the data itself.

When managed separately, the 2D quantity information is displayed in conjunction with the 2D drawing through a dedicated application.

Figure 3 shows an embodiment of the menu of a dedicated application in the volume and calculation basis visualization comparison management system using 2D data of the present invention, and explains each menu.

When explaining several menus (icons) in Figure 3 in detail,

③ The color of structural and finishing objects can be selected as desired by the user through the member selection icon.

④ You can select the floor to check the output quantity and basis through the floor selection icon and move to the floor where you can check the output quantity and basis along with the drawing of that floor.

In addition, through the ⑤ and ⑥ structural and finishing object selection icons, the output quantity and basis can be repeatedly selected for each structural object and finishing object, and the product quantity and basis can be confirmed by selecting the object for which you want to check.

As shown, the dedicated application of the present invention is operated with icons on the menu for mouse selection, member selection, color management for each member, floor selection, structural object selection, finishing object selection, calculation history management, etc.

For example, if you select the color management icon for each member, you can select an appropriate color to correspond to the items of the frame or structural member such as foundations, columns, and beams and manage them according to the user's convenience.

Usually, a building consists of multiple floors from the basement to the ground and the rooftop, so when you select the floor selection icon, the dedicated application uses its own converter to extract 2D drawings for each floor from the BIM (3D) drawing.

Through the dedicated application, the boundary of each floor can be freely set, such as the bottom or top of the slab, the top or bottom of the column, etc., and the installation boundary of the formwork, joint location of rebar, joint area when pouring concrete, etc. can be set.

Figure 4 shows how when selecting the 'structural object' icon in a 2D drawing displayed on a dedicated application, the color is converted to the color specified for each member.

In Figure 4, beams, columns, and retaining walls were selected as examples.

Figure 5 shows the process of selecting the 'member selection' icon following Figure 4 and designating the desired member by dragging or clicking the structural object on the 2D drawing with the mouse.

This is a function implemented for the purpose of visually recognizing the selected object for the user to check by specifying a color for each object and displaying the selected object in color.

Figure 6 shows the process of selecting the 'shopping cart' icon to list up the members specified in Figure 5 and filtering the listed list.

Existing quantity calculation sheets list items and details for each item uniformly in Excel format, making it difficult for users to select and check only the quantity of the desired area.

Accordingly, in the present invention, as shown in Figure 5, the user sets the desired area by a simple action of dragging or clicking the mouse,

As shown in Figure 6, it is characterized by processing (selecting or deleting, etc.) and filtering.

This is a function to select a member in a drawing and store the selected member separately as a shopping cart function, and is a function implemented for the purpose of matching the selected member in the drawing 1:1 with the output quantity by member.

Figure 7 shows the process of checking the position of the member on the 2D drawing in real time when a member is selected from the list.

When performing the filtering process in FIG. 6, it is essential to visually and intuitively check for members as shown in FIG. 7 in order to prevent user mistakes and errors.

Figure 8 shows the calculation sheet for the member displayed by selecting the 'View calculation sheet' icon in Figure 7.

Here, the information of the selected member is listed at the top, and through the list information, information such as the member's code name, length, connection status, thickness, left and right anchorage length, and number of joints can be checked. When the member is selected, the member is displayed at the bottom. A function was implemented to check the product name, standard, calculation formula, and quantity.

As shown, at the top of the dedicated application screen page, 'planar data' including basic floor, length of member, quantity required, fixation of rebar and use of hook, type and size of formwork, etc. are displayed, and any flat member can be selected. When selected, a 'calculation sheet' containing specific product name, specifications, size formula, quantity, etc. is displayed at the bottom.

You can save and print (Excel) the information using the 'Save' and 'Print' buttons at the top right.

The plan data and calculation sheet function as 2D quantity information of the present invention.

Figure 9 shows an example of use of the save button or output button in Figure 8.

As shown, the work scope can be managed on a period-by-period basis through the function of saving the calculation of members selected by the user, and it is intended to be used as confirmation data for payment or receipt of work.

Figure 10 shows how a detailed calculation sheet is displayed by selecting the 'Calculation Management' icon on the dedicated application.

Figures 39 to 43 compare the differences between 2D quantity information, which is quantity information based on 2D drawings, and BIM (3D) quantity information, which is quantity information based on 3D drawings such as BIM, and simultaneously show the 2D calculation and BIM (3D) calculation in the present invention. It illustrates the concept of comparing books.

Figure 44 shows a scene in which detailed calculation details are displayed as a pop-up by selecting a member on a drawing and viewing details in the present invention.

The main features of the present invention are explained based on FIGS. 39 to 44 as follows.

Figures 39 to 43 compare the differences between 2D quantity information, which is quantity information based on 2D drawings, and BIM (3D) quantity information, which is quantity information based on 3D drawings such as BIM.

To be specific,

As shown in Figure 39, in calculating the amount of slab reinforcement, the 2D quantity information is calculated by dividing the total span of 1500 mm by the reinforcement spacing of 200 mm to calculate 7.5, and rounding this amount according to the manual is added by 1, so a total of 9 reinforcement amounts are calculated.

At this time, BIM (3D) quantity information is accurately distributed and arranged on the drawing, so a total of 8 are calculated.

Therefore, there is a difference in that 2D quantity information is calculated one more than BIM (3D) quantity information.

As shown in Figure 40, in calculating the joint length of slab reinforcing bars considering jointing and anchoring, 2D quantity information is obtained by dividing the total span of 1800mm by the reinforcing bar spacing of 200mm according to the manual to calculate the number of 9 joints and multiplying by the joint length of 400mm, for a total of 3600mm ( 9×400) is calculated.

At this time, the BIM (3D) quantity information accurately calculates the number of 7 joints and 2 fixing parts, and multiplies the number of 7 joints by the joint length of 400mm to calculate 2800mm (7 × 400). The small amount of settlement length (α) that occurs is added to calculate a total of 2800mm+α.

Therefore, there is a difference in that 2D quantity information (3600) is calculated more than BIM (3D) quantity information (2800+α).

Figure 41 is an example of calculating the amount of reinforcement for column bars and reinforcing bars of columns, slabs, or walls.

As shown, in calculating the column band of the column, the 2D quantity information is calculated by multiplying the width of the column of 500mm, including the concrete cover thickness, by 4 to calculate 2000mm, and the BIM (3D) quantity information is calculated by multiplying the actual length of the column band by 4, which is 480mm. Add a small amount of hook length (β) to calculate a total of 1920mm+α.

Therefore, there is a difference in that 2D quantity information (2000) is calculated more than BIM (3D) quantity information (1920+α).

In calculating the amount of reinforcement for a slab or wall, the 2D quantity information is calculated by multiplying the total length of the slab or wall (700 mm) by 4 to calculate 2800 mm, and the BIM (3D) quantity information is calculated by multiplying the actual length of the reinforcement bar (670 mm) by 4 to obtain a total of 2680 mm. Calculate

Therefore, there is a difference in that 2D quantity information (2800) is calculated more than BIM (3D) quantity information (2680).

Figures 42 and 43 show the quantity calculation of the side formwork of the beam.

As shown, 2D quantity information is obtained by subtracting 0.15m of slab thickness (TS) from 1m, which is the sum of beam height (D) and slab thickness (TS), multiplying this by 5.8m of beam length (LL, RL), and multiplying by quantity 1 to obtain 9.86. Calculate ㎡. This includes the area where the small and large beams overlap (ACV) of 0.75㎡. However, BIM (3D) quantity information more accurately calculates 9.11㎡ by subtracting 0.75㎡ of the area (ACV) of the area where the small and large beams overlap.

Therefore, there is a difference in that 2D quantity information (9.86) is calculated more than BIM (3D) quantity information (9.11).

As such, the 2D quantity calculation standard is not wrong, but due to the limitations of manual work, small quantity deduction work is not performed, so the quantity calculated is greater than the actual construction quantity. On the other hand, the BIM (3D) quantity calculation standard calculates the quantity most similar to the actual construction quantity, and the surcharge rate that must be taken into account due to damage, spilling, or cutting is applied to the quantity standard calculated in this way.

However, there are existing differences between BIM (3D) drawings of buildings, BIM (3D) quantity information based on the BIM (3D) drawings, and 2D quantity information based on 2D drawings calculated according to certain standards. Not only that, but the calculation basis was not clearly exposed, making it difficult to compare and verify each other, and even for experts in quantity calculation, it was inefficient as it took a lot of time to review.

Even if you are a non-expert in the entire construction industry process, from design to construction and maintenance,

By using the program or dedicated application of the present invention, when a member or area is selected on the drawing, BIM (3D) quantity information and 2D quantity information are compared with each other, including the calculation basis, and are displayed together with the location of the member, etc., so that it is intuitively desired. Quantity information can be selected and verified.

Previously, there were various quantity calculation methods depending on the person calculating the quantity. Therefore, high human errors occurred due to manual input work through drawings according to this quantity calculation method, and there were many cases of inconsistency between drawing information and quantity calculation sheets.

Also, when the drawing was changed, the statement was duplicated and re-created through recalculation.

If the quantity calculation for a partial statement was necessary because branching of quantity calculation through the details was not done, the required quantity was recalculated.

The present invention is intended to improve the existing problems described above,

Quantity calculation through drawings increases the calculator's understanding of the work and reduces human errors (the calculator can check the exact quantity calculation area and view the calculation formula in real time).

It is a drawing input method that minimizes the manual input of the calculator, and the quantity calculation formula is automatically changed when the drawing is changed.

In addition, the statement and the quantity calculation drawing are linked, so when the quantity calculation is modified in the statement, it is automatically reflected in the quantity calculation formula.

It is easy to review and analyze quantity calculation formulas by selecting objects (members or areas) in drawings through a dedicated application.

Additionally, since the statement can be viewed in the drawing, a partial statement can be executed by selecting an object on the drawing.
