The work type object assigning unit 140 assigns the name and description of the work type object to the building object in order to map the project work specification structure history master to the building object data. That is, as shown in FIG. 6, the name and description of the work type object are assigned to the building object. In the method of assigning the work type object to the building object, the category, name, The name and description of the work type object, which are sub information of the category, name, and type, are automatically input for the same category, name, and type. In addition, the name and description of the work type object can be added from the project task description structure history master 300 if necessary.

Next, the data mapping unit 150 maps the project task description structure history master and the building object data allocated the work type object to each other. As the data are mapped to each other, various data can be calculated. The mapping can be one-to-one or many-to-many. Therefore, the activity-specific information for the schedule and the process management is generated according to the mapped information. As shown in FIG. 7, the activity information is compared with that before the mapping, and after the mapping, information on the type of work is entered into a code form.

In the project management system 30, the entered data such as the execution schedule and the default payment timing are transmitted to the existing history management unit 170 .

FIG. 2 shows a flowchart of a BIM operation management method according to the present invention. As shown in the figure, a BIM operation management method according to the present invention is performed by a computer using 3D modeling data constructed by the 3D modeling program 10 and process management data created by the process management program 20 do. Specifically, the BIM operation management method according to the present invention includes a step S22 of registering a name of a project first, a step S2 of creating a project task description structure detail master data before uploading data in the process management program, (S3) of extracting building object data from the stored data, and a step of extracting the building object data from the stored object data, A data mapping step (S5) in which data is mapped according to the assignment of the work type object, and a quantity calculation step of calculating the quantity of the activity information, the schedule information and the quantity information data A data transfer step S7 for transferring the calculated data to the project management system 30, By a data and program data transmitted from the control system it sent gajeok made of a ready-management step that manages shelf.

The data upload / storage step S2 includes a step S21 of uploading / storing the BIM attribute building information data converted from the 3D modeling program to the IFC file, and a step S21 of using the process management attribute data converted from the process management program to the XML file And a step (S22) of uploading / storing the project task description structure history master data. The two steps may be mutually exclusive. The BIM attribute building information data consists of property information of the building object itself such as shape, category, family, and type for the objects of the building structure, and numerical information about length, quantity, area and volume. In addition, the data includes a number of layers where the object is located and position information composed of the parts designated in each layer when the layer is composed of a plurality of layers.

As shown in FIG. 3, a step S22 of creating the project work specification structure details master data using the process management attribute data converted into the XML file is performed from the process management program. Specifically, the item of the work breakdown structure (WBS) and the details of the item are created for each project, and a project WBS history master is created. First, to create an item of the project WBS, data is loaded from the standard WBS history master and the WBS item 310 is added or deleted to complete the project WBS item 310 (S221). These items include items of work type of the overtrade type (312-1), the hollow type (312-2) and the small type (312-3). Further, as shown in FIG. 4, a work type code 311 for distinguishing the large type, the hollow type, and the small type may be further included. When the WBS item 310 is added or deleted according to the project in the standard WBS item, the details of the smallest item in the WBS structure are created (S222). The details of the small craft means that the name and description of the work type object are created. A work object refers to a process object that needs to be processed by work type. As shown in FIG. 4, a work type object 320, which is an object description of a project, is created. The work type object includes a name 322 and a description 323 of the object. The specification 323 includes specification, unit, material unit price, labor unit cost, unit cost, and the sum thereof. Further, a description code 311 for distinguishing the name and the description may be further included. When the above configurations are created, the project object details are also completed (S222). Although not shown in FIG. 4, process management information is also input, and process management information is also included in the project WBS history master. When the project WBS history master data is completed, the data is uploaded and stored (S223). FIG. 4 shows an example of a project type item 320, which is a detailed item of the brick construction (small type) among the project WBS items. In other words, the description code, the name and the details of the object of the project work for the brick work are shown, and one work object for one small work consists of one or more.

The building object data extraction step S3 extracts property information on the shape, category, family, and type of objects constituting the building structure from the BIM attribute building information data, numerical information of length, quantity, area and volume, The location information of the building object data is extracted. That is, from the BIM attribute building information data, position information indicating which layer of the building constitutes one object constituting the building and attribute information such as the shape, name, and purpose of the object held by the object , Numerical information such as a length, a quantity, an area, and a volume displayed along with the attributes of each object are extracted. That is, attribute information having information such as a material, finishing or size, and numerical information corresponding thereto are extracted together with names, uses, and the like of wall, ceiling, floor,

The work type object assigning step S4 is a step for inputting the work type information to the extracted building object data. That is, the 3D data forming the building structure and the process management data can not be matched with each other, so that the building objects, which are individual units of the building structure, and the process management data can be mapped to each other. Therefore, in order to map the process management data to the building object data, the name and description of the work type object, which is the type information of the process management data, should be allocated. 5 and 6, the work type object assigning step is to input a work type object for an individual object of the building object data 400. In FIG. 5, a cement brick having a category wall and a family For the object ex.2, the name and description (ex.3) of the work type object in Fig. 6 are created. The name and description of the work object are first loaded automatically from the standard object description master by the name and description. The criterion to input is based on the category, family, and type of the building object. That is, the building object having the same category, family, and type as the category, family, and type data of the standard object description master automatically enters the details of the object type, details of the category, family, and type of the standard object description master. (504) or deletes (505) the automatically entered work type object according to the project to complete the step of assigning the work type object. Also, the name and description of the work type object can be added from the project WBS history master data. FIG. 6 shows that the name and description of the work type object of ex.3 are input to the building object of ex.2. A description code 501 for distinguishing the work type object may be further included in addition to the name and description of the work type object. The specification 503 of the work type object includes specifications, units, calculation formulas, and the calculation formula inputs an expression determined according to the name of each work type object.

The data mapping step S5 is a step in which the project task description structure history master data is mapped to the building object data to which the work type object is assigned. Once the work object is assigned to the building object data, the object is automatically mapped. Then, a quantity calculation step is performed to calculate various data according to the mapping (S6). The data includes activity information, which is operation information on a process object of the individual work object for the building object, schedule information of individual work object, and quantity calculation information. The quantity calculation information may include a quantity of the calculated work type object and a specification or cost which is a detailed specification of the quantity. Also, as shown in FIG. 7, when the building objects are mapped, the detail codes for the respective building objects can be created and managed. 7 (a) is a building object description code possessed by a building object before mapping, and Fig. 7 (b) is a detail code of a building object after mapping. The detail code of the building object according to FIG. 7 (b) includes the type of work item of the large type, the hollow type, and the small type. As shown in FIG. 6, one or more work type objects for the building object are constituted.

The data transfer step S7 is a step of transferring various data calculated from the water amount calculation step S6 to the project management system 30. [ In general, the project management system 30 transmits activity information, schedule information and quantity calculation information, which are data for managing a project. The activity information is work information that should be made to build a building. That is, each activity must be performed to build a building, and each activity is eventually included in the work object. For example, among the work type objects shown in ex.3 in Fig. 6, the work type object of "cement brick building" is an example of one activity, that is, a work to be performed to form a building constitutes an activity.

The basic history information input and transmission step S8 is a step of inputting and managing the basic information according to the activity information calculated in the quantity calculation step S6, the schedule information and the quantity calculation information, and the execution schedule transmitted from the project management system 30 do. That is, the project management system 30, which manages whether or not the work is completed and the cost is paid, is transmitted to the ready-made history data such as the execution schedule and the ready payment time, Lt; / RTI >

If there is a schedule change S302 or a design change S301, an instruction is directly sent from the project management system 30 to the process management program 20 or the 3D modeling program 10 and the 3D modeling program 10 The modeling engineer changes the design drawing to convert it into an IFC file, and transmits the IFC file to the BIM operation management system 100.
