Description

TECHNICAL FIELD Calculation method, apparatus and method for calculating structure construction cost by analysis of drawing file {A METHOD AND THE DEVICE TO ESTIMATE COST OF CONSTRUCTION BY MEANS OF ANALYZING DRAWING FILES, AND RECORDING MEDIUM THEREOF}

The present invention relates to a method for calculating a construction cost of a structure by analysis of a drawing file, a recording medium recording the device and the method thereof, and more particularly, to a list of materials required for the construction of reinforced concrete and steel buildings and the respective materials from the drawing files. Calculate the construction cost by analyzing the drawing file to obtain the total area, volume, weight, and length, and to calculate the total cost required for the construction of the building by substituting the first cost for each material. A method, an apparatus, and a recording medium recording the method.

      In general, the calculation of construction cost is commonly used as 'accumulation'. At present, people can directly check the drawings to understand the materials required for the structure, and then check the volume and the first price from the elevation, floor plan, and cross-section. Will yield

      At this time, the structure refers to the components constituting the building, such as columns, beams, slabs, the elevation is a view of each side from the outside of the building, the top view and the cross-sectional view is a perspective view of each side of the entire building.

      The floor plan includes a floor plan for each floor of the building, and the cross section includes a transverse cross section and a longitudinal cross section.

      On the other hand, the domestic technology similar to the above-described calculation of construction cost, the 'approximate construction cost calculation method of road construction' published in Korean Patent Application Publication No. 2010-0092307, and the Korean Institute of Architecture Papers-Planning System (ISSN: 1226-9093) No. 20 Kwon, No. 12, pp.89-97, (2004), 'Automation of Quantity Estimation from Drawings Using IFC Models', and Korean Institute of Construction Engineering and Management Vol. 4, No. 1, pp. 114-121, (2003).

      'Schematic construction cost estimation method of the road construction' according to the prior art, the step of receiving the earthwork, side-hole, pavement parameters required for civil engineering work; Calculating a quantity of materials required for construction by applying a regression model for each variable; Calculating earthwork construction cost, sidehole construction cost, paver construction cost by multiplying the earthwork quantity, the sidehole quantity, and the paving quantity by unit price; Including a step of calculating the total construction cost by adding all the earthwork construction cost, side-hole construction cost, paver construction cost, it is characterized in that the total cost required for the road construction.

      However, the method of estimating the rough construction cost of the conventional road construction is not a method of calculating the construction cost from the required materials by analyzing the drawings, but receiving the variables necessary for the regression analysis to calculate the construction cost by statistical inferential inference. In other words, there is a problem that the calculated construction cost is not accurate.

      According to the prior art, 'automatic calculation of quantity from drawings through IFC model' includes converting a drawing file created in ArchiCAD into an IFC instance file; Determining the type of quantity calculation method; A quantity calculation step of automatically calculating a volume for each part of a building by obtaining a spatial hierarchy structure from a file created based on an Industry Foundation Classes (IFC) integrated architecture model; The method may include outputting and storing quantity information, and obtaining quantity information from a drawing file.

      However, the automated study of quantity calculation from drawings through the IFC model does not directly analyze the drawing file, but converts the drawing file into an IFC instance. A file can be created, which is customary for building elevations, floor plans, and cross-sections, because it is very difficult for architects to create drawings of buildings in such a way, and the automated study of volume calculation from drawings through the IFC model There is a problem that it is almost impossible to generate a correct IFC instance file from the created drawings.

      As an example, looking at the results demonstrated in the automated study of quantity calculation from drawings through the IFC model, there is a problem that it is impossible to apply it to the actual construction cost calculation with about half of empty material depending on the building part. Done.

      The 'framed amount calculation algorithm of reinforced concrete tank' according to the prior art, in calculating the framed amount of the reinforced concrete building, slab quantity calculation method; Pillar volume calculation method, wall volume calculation method; And a method of calculating the amount of the treasure, and analyzing the boundary of each member to enable a more accurate quantity calculation.

      However, the slab quantity calculation method includes the steps of inputting a long side and a short side length; Inputting a concrete deduction area; Comprising the step of calculating the form quantity, and the disadvantage that the person has to enter the length and number of the most important long side and short side directly, the column quantity calculation method for inputting the width, thickness, height, etc. for each type of column and It includes the step of excluding the slab thickness of each layer and the step of calculating the form quantity, which also has the disadvantage that the size and number of the most important width, thickness, height, etc. must be entered manually by the person. Inputting an end length at both ends of the retaining wall; Entering a value to be deducted from the floor height; And a step of inputting a symbol or a dance of the lower beam, which has a disadvantage in that a person must input the dimensions and the number, and the method of calculating the amount of the treasure includes: inputting from the centerline of the beam to the centerline; Inputting the length or symbol of the beam and column foundation across both ends; Deducting the quantity of each pillar type; Entering the type of formwork to be deducted from the slab, all dimensions and the number has the disadvantage that a human must enter.

      In other words, the algorithm for calculating the amount of the frame of the reinforced concrete tank according to the prior art can be used to calculate the accurate construction cost when all the dimensions are given, but there is a problem that it is impossible to calculate the amount of the frame from the drawing file. The method of calculating the quantity of the solution is not accurate, and there is a problem that incorrect results can be obtained if there is not enough time due to miscalculation in dimension input.

      Similar technologies outside the United States include the United States Patent Number 5,189,606 'Totally integrated construction cost estimating, analysis, and reporting system' and the US Federal Journal ASCE. (American Society of Civil Engineers; ISSN: 1943-7862), Vol. 124, No. 3, pp.210-218, 1998 'Neural Network Model for Parametric Cost Estimation of Highway Projects' Neural network model for estimation).

      'Complete integrated construction cost calculation, analysis and reporting system' according to the prior art is a construction cost management and analysis system (CCMAS), as well as major weapons program (Administrative, medical, medical) Analyze the construction and life cycle costs of facilities associated with runways, taxiways, etc., and provide an analogy estimate from facility data.

      However, the similar estimation function of the fully integrated construction cost calculation, analysis, and reporting system differs greatly from the exact construction cost required for bidding or executing a construction, so that only a rough cost can be calculated before planning the construction. There is a problem.

      The neural network model for estimating the parameter type cost of the highway plan according to the prior art is similar to the method for estimating the schematic construction cost of the road construction described above. Instead of applying a regression analysis to the parameter estimation, an artificial neural network (Artificial) The neural network method is used to train the neural network based on 18 existing highway construction cases and input the variables to calculate the construction cost immediately.

      However, the neural network model for estimating the parametric cost of the highway plan also does not calculate the construction cost from the required material by analyzing the drawings as described above.

      Therefore, the present invention is devised to improve the conventional problems as described above, the purpose of which is to calculate the construction cost by analyzing the drawing file in order to automate the calculation of the cost required for construction, and integrated through this automation process It is to provide a method for calculating a structure construction cost by analyzing a drawing file, an apparatus, and a recording medium recording the method so that the time required for the present invention can be shortened.

      Another object of the present invention is to provide a method for calculating a construction cost of a structure by analyzing a drawing file, an apparatus, and a recording medium for recording accurate construction cost by using information such as dimensions, lengths, and accumulations described on the drawings. In providing.

      In other words, there are a variety of techniques for calculating construction costs, but there are no examples of analyzing the drawings directly to determine the phase and calculating the amount of the frame.

      Although the automated study of quantity calculation from drawings through the above-described IFC model may be mistaken as an example of analyzing the drawings, in practice, the drawings are first converted into an IFC instance file and then the converted information is not analyzed. Since IFC instance files have been analyzed and the process has not been converted to IFC instance files, it is impossible to say that the drawings have been analyzed, and the instance files collectively describe all the materials and their locations, volumes, masses and types. As it is recorded, anyone can easily calculate construction cost.

It includes the process of step S 4 and the construction cost calculation step S 5.

      In the standard drawing generation step S 1, a standard drawing 121 is generated from at least one drawing file 101 and at least one structural drawing 111 input to the drawing file converter 100. In the structure list generation step (S 2), as the drawing of the standard form generated in the standard drawing generation step (S 1) is input to the structure list generation unit 201 side of the construction cost calculation unit 200, FIG. As shown in the figure, a list of various structures including columns, beams, slabs, slab reinforcing bars, and other structures will be generated.

      Herein, the structure list generation step (S 2) will be described in more detail. Generally, the column list is CON'C COLUMN LIST, the beam list is CON'C GIRDER & BEAM LIST, and the slab list is CON '. Represented as C SLAB LIST, the rectangular area closest to the position on the drawing can be obtained (see FIG. 3).

      In this case, if each list is not found in the drawing, an area of each list may be input from the user.

      First, for the column list,

      1) After all the objects corresponding to the line segment and face in the area are obtained, the intersections of the objects can be obtained, and the face consists of four points. You can get it. In other words, all the objects constituting the area can be converted into line segments consisting of two points.

      If two points are given, the equation of the corresponding straight line can be obtained and the contact point for each straight line can be obtained.

      2) By connecting the contact to reach the outermost object (line segment), it is possible to remove the object belonging to the shape, wherein the shape 303 is not in contact with the surrounding objects in any case.

      3) Each intersection may be used to generate an intermediate list as shown in FIG. 9. In this case, in the case of the second floor 302 overlapping rows, the intermediate lists may be input to rows of different columns.

      4) The layer and the sign are separated and except for the above form, a list as shown in FIG. 5 can be prepared.

      In addition, in the case of the beam list, it can be generated by the same method as the above-described column.

      In the case of the slab list, the number and length of the sign and the thickness, the long span and the short span can be generated by the same method as the column. In the case of the reinforcing bar required in the beam, as shown in X1, X2, X3 (303) of Figure 3 reinforcement is reinforced only on the outer shell (exterior), the outer shell is reinforcing bars (BEND), and reinforcement in a straight line Three types of rebar, such as (straight), should be distinguished.

      1) In any case, the area corresponding to the slab shape can be obtained by not touching the surrounding objects.

      2) Search the first sign in the area corresponding to the form and find the nearest point.

      3) Find the line segment containing the point and record the length.

     4-1) If the length is the longest on the same axis, it can be judged to be straight.

     4-2) If the line segment is shorter than the length corresponding to 4-1) and there is no line segment connected to a point far from the point 3), it may be determined that the reinforcing bar is only reinforcement.

      4-3) If there is a line segment shorter than the length corresponding to 4-1) and connected to a point far from the point 3), the outer shell may be divided into reinforcing bars arranged at an upper portion and an inner portion of the lower portion.

      On the other hand, in the case of creating a list of structures (retaining walls, stairs, etc.) other than the above-described columns, beams, slabs,

      1) The area of the structure can be input from the user.

      2) All codes 401 including the reinforcing bar code (HD number, D number, etc.) in the area can be searched (see Fig. 4).

      3) The nearest point 402 may be searched and the opposite point 403 may be searched for in the object including the point.

      4-1) If the object connected to the point is the region 404, the number of points included in the region may be calculated.

      4-2) If not, repeat the above steps.

      4-3) If there is no number of points included in the region (405), the line segment passing through the region may be searched and the length may be calculated.

      5) The point 406 that is not indicated can be processed as a reinforcing bar that uses a neighboring point to obtain a straight line and indicates a point included in the straight line.

      6) The thickness (object consisting of only numbers) 407 of the structure can be retrieved.

      Through the process as described above, it is possible to prepare a list of other structures consisting of the thickness of the structure, the type of rebar, and the length of the rebar.

      On the other hand, in the drawing analysis step (S 3) it is to calculate the dimensions and number of each structure by analyzing the symbols and dimensions on the drawings of the cross-sectional view and the plan view converted from the drawing file conversion unit 100 in a standard format, the structure In the volume calculation step (S 4), the structure quantity calculation unit 202 of the construction cost calculation unit 200 iterates over the codes for each floor, code, shape, dimension, and area, and reinforces according to length and volume. The amount of formwork is calculated through the concrete volume and the corresponding outer area.

      Here, for the calculation of the volume of structures corresponding to columns, beams, slabs,

      1) When the elevation view and the plan view (refer to FIGS. 6 and 8) converted to the standard format are input, the structure quantity calculation unit may generate the dimension list as shown in FIG. 6.

      2) If the sign is a 'pillar', the structure quantity calculating unit compares a sign on the floor plan with a sign input in the column list shown in FIG. 5, and corresponds to the floor, sign, and shape of the nearest object (circular or polygonal). According to the number of 'pillars' can be calculated.

      3-1) If the sign is 'beam', the structure quantity calculating unit may obtain the length by searching for the object (straight line, surface) closest to the sign on the floor plan.

      3-2) Of the lengths in the drawing of FIG. 7, the dimension closest to the length obtained in the above 3-1) can be obtained.

      3-3) The number of beams can be calculated according to the floor, code and dimensions.

      4-1) If the sign is 'slab', the structure quantity calculation unit may obtain four lengths by searching for the closest objects, respectively, in the top, bottom, left, and right of the floor plan.

      4-2) By comparing the four lengths obtained in the above 4-1) of the length shown in Figure 7 can be obtained the closest dimension.

      4-3) After calculating the area of the area, the number of 'slabs' can be calculated according to the floor, the sign, and the area, and the two lengths can be separated.

       5) The structure quantity calculation unit may calculate the height of each floor from the dimensions obtained on the elevation.

      6) If there is an object whose sign cannot be found, the object can be displayed and the user can directly enter the sign.

      And for the calculation of the volume of the structure, except for columns, beams, slabs,

      1) The user can specify the object corresponding to other structures.

      2-1) If the 'length' value exists in the list of other structures, the volume can be calculated using the length of the object, the length of the list of structures and the thickness.

      2-2) If there is no 'length' value on the structure list and the object is 'face', the volume can be calculated using the area and thickness.

      2-3) If there is no 'length' value on the list of other structures and the object is a 'segment', the volume can be calculated using thickness by assuming a plane by connecting adjacent points.

(eg HD10 @ 300). The main root can be calculated by multiplying the height and number of floors, and the length of the root can be calculated by dividing the perimeter of the column and the height of each floor by the interval. Auxiliary roots can be calculated using the number of heads, spacing, and floor height. The information may include information such as a sign, an area, a location, an upper root, a BEND, a lower root, and a root. The position for each code can be divided into a point (END), which is 1/4 from both ends of the beam, and a middle part (CENTER) except for both ends of the beam. If known, the amount of each material can be calculated according to conventional techniques. The slab may include information about the sign, location, shape, thickness, and types of reinforcing bars in the long and short widths. Rebars for each width are at least one strand, and the types can be selected to yield the required amount, as described in the Structure List Generation step. The reinforcement method of each reinforcing bar is determined according to the prior art. Other structures may include information such as signs, thicknesses, lengths, rebars, etc., and rebars may include types and lengths. In the case of other structures, the number of rebars may be several, and may include reinforcing bars having no length. The length of the other structure is the length of the structure itself, the length of the reinforcing bar may be the length of the reinforcing bar occupies the structure. In the case of other structures, the number of rebars may be horizontally or vertically, and there may be a structure without reinforcing bars. However, because the reinforcement spacing is shown in the drawing, it is possible to know the amount of reinforcing bars needed only by knowing the length of the cross section. Concrete, like columns, beams, and slabs, stores the cross-sectional area and then multiplies the lengths in plan and cross-section, so that the amount and size of concrete required can be calculated, and the exterior area can be calculated.
