Hereinafter, the present invention will be described in more detail with reference to the drawings.
The present invention relates to a method and a system for constructing a structural object such as a concrete structure, a concrete structure, a concrete structure, a reinforced concrete structure, a steel structure, And the product of building type unit price and structural object volume (㎥) is applied to the building information model, and the construction finishing material is the construction material (S100a) for classification of structural objects and finishing materials for building estimate estimation using BIM; Each construction type classification step of the structural object and the finishing material (S100b); A step (S100d) of extracting a greatest value corresponding to each construction type from the database; A step (S100c) of calculating the unit price of the building structural object and the finishing material by summing the greatest of each construction type; The structural object volume (m 3) information is multiplied by the unit price of the generated structural object unit in the building information model through the BIM (S200) for calculating the unit price information, the structural object unit volume (m 3) and the finishing material unit area A step of calculating S200c; A step (S200a) in which the finishing material area (m2) information is multiplied by the generated finishing material unit price in the building information model; And generating an information model including the generated structure code and a finishing code, a structural object included in the information model, and a result of estimating a finishing material estimate, and a step of calculating and classifying the unit cost information.

The unit price information calculation and classification method for estimating an estimate of an architectural structure object,

More specifically, the unit price information calculation and classification method for estimating an estimate of an architectural structure object will be described with reference to FIG. Four objects (S300c) of concrete, formwork, steel, and steel, which are the structural structural objects used in the present specification and claims, correspond to the selected part (S300b) of the base structure, the column, the beam, the retaining wall, the slab, (Steel reinforced concrete), SRC (steel reinforced concrete), and SC (steel concrete) structures, which are the top architectural structure construction types. It is a structural site classification corresponding to a construction type (S300a). Therefore, concrete object, concrete object, formwork, reinforcing steel, steel frame object, which is an object of construction, is the same as that of FIG. 5 based on object including upper classification, and each structural object means an individual element constituting an independent system.

For example, RC-WAL-C structure code means concrete applied to the retaining wall of reinforced concrete construction, SRC-COL-C structure code means concrete applied to columns of steel reinforced concrete construction, , It is possible to generate more structure codes by adding structural objects.

When the code of the structural object is selected (S310), the construction type of the construction standard applied to each concrete, formwork, reinforcing bar, and steel frame object is classified (S320a) in order to calculate the maximum value of the structural object.

For example, the types of construction applied to reinforced concrete column objects include construction types such as cement, sand, gravel, labor (concrete and labor costs), and equipment finishing.
In addition, the types of construction applied to the rebar objects include the construction types such as small iron wire, labor (steel bar, ordinary laborer), and machine tool finishing.
In addition, the type of work applied to form objects includes plywood, timber, wire, nail, stripper, mold work, ordinary worker, and tool finishing.

In addition, the one-dimensional magnitude of the classified structural object construction type is extracted from the database (S320b), and the magnitude of each magnitude of each construction type of the structural object is substituted into the construction type order of the structural object, (M < 3 >) (step S320c).

For example, each construction type of concrete applied to a reinforced concrete column object can be classified into three types, namely, cement, sand, gravel, labor cost (concrete labor cost, normal labor cost) And the unit cost of the structural object concrete unit volume (m 3) is calculated by summing the unit cost (m 3), which is the cost of each construction type, and the unit cost.

In addition, the unit price m3 of the structural object S300c and the unit price of the building type S3 are multiplied by S320c to calculate an estimate estimate of the structural object S330.

In addition, the generated structure object code (S310) and the estimate estimate (S330) of the calculated structure object are included to generate a structure object information model (S340).

In addition, the code of the structural object information model and the estimate estimation result are outputted and completed (S350).

The unit cost information calculation and classification method for estimating the structural object estimate is completed by outputting the structural object unit cost, the structural object unit volume (m3) operation result value and the corresponding code information according to the selection of the object according to the building structure part.

The unit price information calculation and classification method for estimating an estimate of building finishing materials,

With reference to FIG. 2, a description will be made as to how to calculate and classify the unit price information for estimating an estimate for a building finishing material. The construction finishing material is selected in S400a for the application of the finishing material among the finishing floor IF, wall IW and IC, S400b is selected for the finishing material to be applied to the designated site, And a finishing code including the finishing material information and the finishing material information is selected (S410) as shown in FIG.

For example, the IF-PRO finishing cord refers to mineral elastic waterproofing located on the inner bottom, and the IW-GYP finishing cord refers to a gypsum board located on the inner wall. You can also create more finishing codes by adding finishing materials.

In addition, in order to calculate the maximum value of the finishing material of the selected finishing area, the construction type is classified (S420a).

For example, the types of water paint works on the wall surface include types of construction such as putty, abrasive paper, painter, and instrument finishing.

In step S420b, the maximum degree of each type of the finishing material classified by the type of construction is extracted from the database to be assigned to each type of construction type of the finishing material so that the greatest amount of each type of finishing material is combined, The unit price (unit) (m2) unit price is calculated (S420c).

For example, water-based paints applied to the wall surface are classified into various types of work such as putty, abrasive paper, painter, and instrument finishing, in terms of cost per unit area (㎡) Calculate unit cost, which is the unit cost of water paint (㎡) of the finishing material on the wall surface, together with the cost of each construction type.

In addition, the unit cost (m2) of the finishing material (S400b) and the unit price of the work type (S420c) are multiplied to calculate the estimated cost of the finishing material (S430).

In addition, a finishing material information model is generated by including the generated finishing code (S410) and the generated estimate of the finishing material (S430) (S440).

In addition, the finishing material code and the estimate estimation result are outputted and completed (S450).

According to the unit price information calculation and classification method for estimating the material cost estimate for each finishing site, the finishing material unit price, the finishing material unit area (m2) calculation result value and the corresponding code information are outputted according to the selection of the material for each building finishing site, do.

Subsequently, the worker S100 extracts a job corresponding to the classification of the construction type (S320b) and a job corresponding to the classification of the finishing type (S420b) in the database (S100d) and inputs it to the BIM (S320b) corresponding to the classification of the construction type with respect to the unit volume (m3) of the building in the unit unit price generation module (S100c) of the BIM (S200) to calculate the unit unit price (S320c) A step S420 of generating a fixed unit value S420c of the finishing unit by computing a unit price S420b corresponding to the classification of the finishing type with respect to the unit area m2 of the building, , ≪ / RTI >
Next, a step S340 of generating an information model corresponding to the construction type of the building through the information model creation module S200b of the BIM S200, and a step S440 of generating an information model corresponding to the type of finish of the building .
Therefore, at the same time as the above information model generation (S440) in the structure estimate calculation module S200c of the BIM (S200), the total volume (m3) of the information model is multiplied by the unit unit price S320c of the structure, Along with calculating S330,
At the same time as the above information model creation (S440) in the finish estimate estimate calculation module (S200a) of the BIM (S200), the total area (m2) of the information model is multiplied by the unit price of the finish (S420c) Step S430 is performed
Finally, a structural estimate estimate result corresponding to the information model is output from the structural estimate estimate calculation module (S200c) (S350), and a final estimate estimate result corresponding to the information model is obtained from the finish estimate estimate operation module (S200a) (S450).
