Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that, in the drawings, the same components are denoted by the same reference symbols as possible. Further, the detailed description of well-known functions and constructions that may obscure the gist of the present invention will be omitted. That is, in the following description, only parts necessary for understanding the operation according to the embodiment of the present invention will be described, and it should be noted that the description of other parts will be omitted so as not to distract from the gist of the present invention.

The present invention relates to the implementation of a stand-alone process / cost management system of the web-based 3D process / cost integrated management system. That is, the present invention relates to a web-based BIM (Building Information Modeling) system and a method of operating the same, which are capable of efficiently managing a process and construction cost in construction work. According to the web-based BIM system of the present invention, it is possible to confirm and manage the progress of the process and the cost (for example, construction cost) intuitively and in real time.

In the embodiment of the present invention, the BIM represents modeled information about the project (eg, construction work, etc.), and all internal design elements (eg, rebar, equipment, pipe, etc.), construction schedule, Modeling of buildings by designing them in 3D. In particular, in the present invention, the BIM is from the most basic 3D to four-dimensional (4D) (adding process control considering time to 3D) and five-dimensional (5D) (adding cost control to 4D) It represents the modeling of 3D based on one 3D model. The BIM of the present invention can compare the budget and the execution according to the progress of the project, it can provide an environment that can visualize and intuitively identify and solve the problem. That is, 3D according to the BIM of the present invention allows for smooth communication while correcting design errors and aiding understanding through visualization, while 4D provides a better alternative in construction method and safety through process simulation, schedule, etc. Efficiency can be minimized, and collisions between works can be minimized, and 5D can focus on the core of the problem by monitoring the problem and proactively detecting the severity based on the link between process and cost.

Accordingly, in an embodiment of the present invention, a 3D model based on BIM (3D, 4D, 5D) is linked with EVMS data such as process data and cost data previously stored in an Earned Value Management System (EVMS), and The web-based BIM system can be implemented by converting the linked 3D model into an Internet model to enable simulation on the web.

That is, according to an embodiment of the present invention, by connecting the 3D modeled model data of the construction process and the EVMS that manages the process and cost (eg, construction cost) of the construction work on the web, the progress of the construction work is three-dimensional It can be confirmed graphically, and can provide an environment that can intuitively check construction-related information at the same time.

According to the present invention, as described above, by linking the 3D structure model (model data) and the EVMS data (for example, process data and cost data) for the target structure according to the construction to continuously progress the 3D progress by unit of the actual structure I can express it. This allows a 3D simulation that allows the user or administrator to visually check the process via a web service using a given device (eg, a user device). Also, by linking 3D structures and construction-related data, it is possible to manage 3D information that can be used to view design documents (drawings, specifications) and relevant section data for the selected structure when a specific structure is selected. In addition, according to the present invention, since the 3D model is associated with the EVMS, process and cost information management is possible. In addition, since the present invention is a web-based system, information sharing and smooth communication between the field, the headquarters, and the client are possible.

Hereinafter, the configuration of the system and its operation method according to an embodiment of the present invention will be described with reference to the accompanying drawings. However, since the configuration and operation method of the system according to the embodiment of the present invention are not limited or limited to the contents described below, it can be applied to various embodiments based on the following embodiments.

1 is a diagram schematically illustrating a process of building a system according to an embodiment of the present invention. Referring to FIG. 1, the present invention includes a web (internet) based BIM construction step 10 and a system design step 40 as main steps. The web-based BIM construction step 10 is configured to include a 3D modeling step 20 and an internet modeling step 30 of the structure, and the system design step 40 is a system architecture design step 50. And EVMS design step 60.

Hereinafter, the web-based BIM construction step 10 will be described, and the system design step 40 will be described later.

As described above, the present invention relates to an integrated management system capable of 3D process / cost management by implementing a web-based BIM system linked to an EVMS for a specific site. Therefore, in the present invention, data such as process data and cost data (hereinafter, EVMS data) may be preset in the EVMS configured in the field. A 3D model (model data) that simulates the 3D shape of the structure can be generated for the 3D process simulation expressed as 4D, and a 5D system connecting 4D and cost can be constructed. That is, the present invention can implement a BIM system linked to the EVMS.

Accordingly, in the present invention, 3D modeling for simulation of a specific construction site and a transformation, ie, an internet model, for linking the 3D model (model data) by the 3D modeling to a web-based system can be generated. Specifically, it is as follows.

In the system of the present invention, as shown in FIG. 1, in the 3D modeling 20 according to the web-based BIM construction step 10, the BIM-based 3D modeling 21 and the 3D modeling for the structure to be constructed. According to the object unit segmentation 23 for the 3D model (model data) can be performed.

That is, a 3D model showing a structure in 3D visual form may be generated from a 2D drawing (eg, a plan view of 2D) of a structure for a current BIM application. This example is shown in FIG. 2. FIG. 2 is a diagram illustrating an example of 3D modeling 20 for a 3D model in the web-based BIM construction step 10 according to FIG. 1. In particular, FIG. 2 shows an example of a 3D model (model data) for the 3D visual shape of a bridge generated through 3D modeling from a 2D drawing of a bridge as an example of a structure. According to the present invention, in the process of generating a 3D model from the 2D drawing data, general degree such as correction of drawing error and review of the shape of a complicated structure can be examined, thereby preventing air delay elements in advance.

In the case of the 3D model of the present invention, an accurate BIM model may be constructed by reflecting an error of the drawing indicated in the 2D drawing data. For example, in the case of general 3D modeling, the thickness of the plant joint of the upper flange in the view point girder may be equally designed, but the BIM model according to the present invention reflects the 3D model in consideration of the load, and also based on the internal drawing. Internal structures such as diaphragms and stiffeners can be included in 3D modeling.

Next, according to the present invention, when generating the 3D model as described above, the object division unit, modeling range, and degree of refinement may vary according to the application purpose of the 3D model.

For example, when 3D simulation is the purpose, the 3D model may be divided into minimum units by one unit. In this case, even if the model part is divided into several objects in the daily simulation, the same result is obtained by assigning the same schedule to each object. However, if the purpose is to manage costs through the 3D model, the 3D model can be divided into the minimum and absence and ready-made management units. In this case, it is inevitable to increase the capacity of model data due to many objects. Therefore, considering the application purpose and efficiency of the 3D model, it is necessary to decide the appropriate division of the model.

According to an embodiment of the present invention, in performing 3D modeling from 2D drawing data, it is characterized in that it is linked with a 3D model that generates EVMS data (eg, cost information and schedule information) of EVMS. Therefore, in the present invention, the 3D model is divided into a work breakdown structure (WBS) unit, which is a process management system for systematically managing a schedule of unit processes for each level. That is, the purpose of applying the 3D model in the present invention is for 3D simulation by linking the cost information and schedule information of the EVMS data preset in the EVMS with the 3D model. Therefore, in the present invention, the 3D model is divided into the WBS unit representing the process management system for systematically managing the schedule for the unit process for each level. Examples of the drawings for explaining this are shown in FIGS. 3 and 4.

FIG. 3 is a diagram schematically showing a configuration of standard information of EVMS data constructed in an EVMS according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating an example of FIG. 3. In the present invention, the EVMS can be constructed by standard structure, standard process, standard connection information, etc. for each structure (or facility). As shown in Figure 3, in the present invention, the EVMS can be built by the structure (or facilities) for each standard, standard process (WBS), standard connection information, and the like. Level 7 level (or level 6 level) in the standard process (WBS) is a subordinate activity of the sub activity associated with the standard content and is the unit in which the content of the process and site is the most consistent. For example, as shown in FIG. 3, the 3D model may be divided into sub-activity units of level 7 of the WBS based on the EVMS data of the EVMS set for the specific construction site.

4 illustrates an interworking relationship between a 3D modeling shape of a piers and a corresponding WBS code as an example of FIG. 3. That is, after splitting the 3D model, as shown in FIG. 4, the names of the elements of the 3D model and the corresponding WBS codes may be matched, respectively. Thereafter, the 3D model (model data) may be automatically connected to the EVMS data of the EVMS based on a specific code.

Next, in the system of the present invention, as shown in FIG. 1, the Internet modeling 30 according to the web-based BIM establishment step 10 may be performed. That is, as described above, in order to publish the 3D model (model data) created based on BIM on the Internet, the process of converting the 3D model to the Internet model is performed. In the present invention, the 3D model (model data) created based on BIM can be accessed by a user or an administrator through a web service through the Internet. For this purpose, the 3D modeled model data as described above is an Internet model in which the Internet is accessible. Convert to That is, in the present invention, a process of generating an Internet model for driving 3D simulation in the Internet may be performed.

In general, when the 2D drawing data is simply changed into 3D model data, the number of objects increases exponentially. Therefore, the present invention performs the Internet modeling work to convert the 3D model data into an Internet model.

As the first process of the internet modeling task 30 in the present invention, it is possible to reduce the weight 3D model 31 by reducing the number of objects that are simply converted when performing the Internet modeling task 30. In the present invention, the weight reduction 31 of the 3D model may be achieved by reducing the number of objects belonging to the activity, reducing the surface of the 3D model, and reducing the capacity of the 3D model.

First, the number of objects can increase exponentially when a simple CAD file is converted to 3D. Therefore, in the present invention, weight reduction of model data that is 3D modeled with the number of objects belonging to an activity may be performed first. That is, when converting the number of activities arranged in a simulation unit from the 3D model to the Internet model, it may be converted into an element unit representing each model. As such, an example of the screen according to the object number conversion of the 3D model and the Internet model is shown in FIG. 5.

In general, when the 2D drawing data is changed into 3D model data, the shape of the model data may be distorted. Therefore, in the present invention, the shape of the Internet model is cleaned and reduced in weight through the surface cleanup of 3D modeled model data. As such, an example of the screen according to the shape surface cleanup of the Internet model is shown in FIG. 6. FIG. 6 is a view illustrating a surface cleaning operation to an internet model during an internet modeling operation of the present invention. FIG. 6 (a) shows an example of simply converting the 3D modeled to a shape model, and FIG. 6 (b) shows an example after performing a surface cleaning operation.

In addition, when converting 3D model data into an Internet model, the components (points, lines, and faces) of the model data may increase exponentially. In general, when converting 2D drawing data into 3D model data and converting the data into 3D model data, points, lines, planes, etc., which constitute the 3D model, increase exponentially. Therefore, in the present invention, while maintaining the shape of the 3D model data as it is, to perform unnecessary work to find and organize the components to reduce the capacity of the Internet model. As such, an example of the screen according to the overall surface cleanup of the Internet model is illustrated in FIG. 7. FIG. 7 is a diagram illustrating the overall surface cleanup operation of the Internet model. FIG. 7A illustrates an example of a state in which 2D data is simply converted into 3D data but not yet lightened, and FIG. 7B illustrates an example of a state in which even light weighted work is completed. In this case, for example, in the state of FIG. 7A, data having a capacity of about 477 MB may be converted into data having a capacity of about 150 MB after the lightweighting operation is performed, and the data size thereof may be converted.

Next, as a second process of the Internet modeling task 30 in the present invention, it is possible to give a graphic effect 33 on the 3D model data simulated when performing the Internet model task 30. That is, in the system of the present invention, a virtual effect can be realized by applying a graphic effect to 3D model data. In the present invention, the graphic effect grant 33 may be composed of a texturing operation, a color mapping operation, a rendering operation, and the like.

In general, the simple transformation of 3D model data can result in a single texture of the Internet model, which can be visually monotonous and difficult to distinguish clearly. Therefore, in the present invention, the texture may be performed for each object for application to the Internet model. An example of the screen according to the texture work of the present invention is shown in FIG. 8. FIG. 8 is a diagram illustrating an example of texturing by objects of the Internet model, and shows a state before and after texturing. FIG. 8A shows an example in the case of one texture, and FIG. 8B shows an example in which the textures are different for each activity.

Next, after performing the same texture for each object of the 3D modeled model data (structure), color mapping for each object may be performed. An example according to the color mapping operation of the present invention is shown in FIG.

9 is a view illustrating a color mapping operation according to the present invention. In particular, FIG. 9 (a) shows an example of a case of expressing in a single color, and FIG. 9 (b) shows an example of a case of performing a color mapping operation suitable for the structure of model data. In this case, in the present invention, it is preferable that each object is configured with a small capacity less than a specific capacity (for example, 1MB) so that it can be published on the Internet.

In addition, according to an embodiment of the present invention, in addition to the color mapping operation as described above, it is also possible to perform a rendering operation. That is, according to the present invention, the rendering operation may be performed when converting the model data into the Internet model in order to implement a virtual site that is close to reality when simulating the Internet model. As a result, the structure shape of the model data that is 3D modeled and displayed on the monitor or user device of the integrated management server may accurately describe the structure to be actually constructed. An example showing the results of this rendering operation is shown in FIG. 10. FIG. 10A illustrates an example of a result obtained after conversion without rendering, and FIG. 10B illustrates an example of the result after rendering and conversion.

Meanwhile, as described above, when 3D modeling is completed, a system architecture for linking EVMS data (process data and cost data) and web-based BIM information is constructed (during the system design step 40 of FIG. 1). Corresponds to the system architecture design phase (50)). Specifically, the present invention builds a system architecture that automatically updates data by connecting process data and cost data of EVMS with an internet-based 3D process / cost management system. Therefore, hereinafter, the construction operation of linking the EVMS data pre-built in the EVMS for a specific construction site and the model data according to the web-based BIM as described above will be described. In the present invention, the system architecture may be configured as an open architecture web system, and thus may be compatible with the organic interworking with the existing EVMS.

11 is a diagram illustrating a schematic configuration of a system architecture according to an embodiment of the present invention.

As shown in FIG. 11, the system architecture according to the present invention has a three-tier structure, and includes an application layer, a presentation layer, and a data access layer. It is configured to include.

In the application layer, the user uses 3D graphics through a compatible 3D player such as DirectX or OpenGL, and the presentation layer representing process data and cost data is HTML that complies with the Web standard. (Hyper Text Markup Language), ASP.NET, Flex, Silverlight, and more. The process data and the cost data, which are the EVMS data, are linked with the EVMS through a web service, and the data obtained through the linking is linked to a relational database management system (RDBMS) (eg, MS-) at the data access layer. It can be managed in a SQL (MS-Structured Query Language) server. Based on this system architecture, it is an open architecture web system that is compatible with the existing EVMS.

As described above, the present invention can be extended to the integrated management system for the communication between the field and the head office by not only implementing a 5D system in conjunction with EVMS, but also drawing, 3D model data, documents, and field pictures required for construction. have. Accordingly, the present invention can smoothly perform a communication function between users who share the security and share the integrated information through different screens according to the user's authority level, and satisfy the needs of various users. Next, the system configuration and the EVMS linkage operation according to the present invention according to the system architecture based system design as described above will be described. That is, the EVMS design step 60 of the system design step 40 of FIG. 1 will be described below.

BIM information can be output. That is, the user device 300 may display a web-based 3D model provided by the integrated management server 200 in conjunction with the EVMS 100 and provide EVMS data associated with the 3D model on a web-based basis. have. Therefore, a user or an administrator can intuitively check and manage processes and costs through the 3D model provided by the integrated management server 200 using the user device 300. In the present invention, the user device 300 may be configured in plural as shown in FIG. 13, and each user device 300 may support access to the integrated management server 200 through the network 400. . Referring to FIG. 14, the model data checking process through the connection of the integrated management server 200 using the user device 300 is described as follows.

That is, a user or an administrator may access the integrated management server 200 through the user device 300 and output the related user interface. Screen examples of the user interface supported by the present invention and operations thereof will be described later. The user interface supported by the integrated management server 200 will be described later. In operation 1405, the user device 300 may request related model data from the integrated management server 200 through the network 400 in response to a request for model data from a user or an administrator through the user interface. Then, the integrated management server 200 may obtain the requested model data from the internal database in response to the request of the user device 300 and provide it to the user device 300 through the network 400 (step 1407). Here, the model data provided through the user device 300 may correspond to web-based 3D model data, that is, an internet model, converted by the integrated management server 200 by an internet modeling operation.

Next, when the requested related model data is transferred from the integrated management server 200, the user device 300 displays the model data transferred through the user interface and provides the same to the user or the manager (step 1409). Then, the user or the administrator may perform at least one function selection for 3D simulation, 3D information management, process / history management, etc. on the model data provided through the user interface in the user device 300 (step 1411). ).

Next, the user device 300 requests the integrated management server 200 information on the corresponding function selected through the user interface as described above (step 1413). For example, the user device 300 identifies a selected function when a user or an administrator selects at least one function for 3D simulation, 3D information management, and process / history management using given model data through a user interface. And request information of model data for the identified function.

Next, when the integrated management server 200 receives an information request for model data from the user device 300, the integrated management server 200 may identify the received request information (step 1415). The integrated management server 200 provides information related to the model data to the user device 300 by internal processing according to the identified information, or obtains related information by interworking with the EVMS 100 according to the identified information. After that, it may be provided to the user device 300. For example, the integrated management server 200 identifies the request information, and if the identified request information is data (eg, EVMS data) that requires interworking with the EVMS 100, providing information on the corresponding information is provided by EVMS ( 100) (step 1417).

Next, when the EVMS 100 receives an information request for specific model data from the integrated management server 200, the EVMS 100 may obtain the corresponding information from the internal database and provide the integrated management server 200. For example, the EVMS 100 may provide various information related to process data, cost data, or details of a specific portion of the model data to the integrated management server.

Next, when the integrated management server 200 receives a response to the information request from the EVMS 100, that is, when receiving information about the model data, the integrated management server 200 reflects the corresponding information in the model data (step 1421). The model data may be transferred to the user device (step 1423). In this case, the integrated management server 200 may apply the information (eg, EVMS data) obtained by interworking with the EVMS 100 to the web-based 3D model data (that is, the Internet model).

Next, the user device 300 may display the model data transmitted from the integrated management server 200 through the user interface (step 1425). For example, according to a function selected by a user or an administrator, model data reflecting results of at least one of functions such as 3D simulation, 3D information management, and process / history management may be displayed on the user interface.

By this procedure, the user or manager can compare the budget and execution according to the progress of the project such as construction work in real time, and visualize it so that the problem and the like can be intuitively identified and solved more intuitively. That is, the 3D simulation function for visual inspection of the process by continuously expressing the 3D progress of the structure by unit by linking the 3D model of the structure and the EVMS data, and the corresponding design book of the specific structure selected when the specific structure is selected in the 3D model And a 3D information management function for providing the section-related data in association with the EVMS data, and a process / history management function for querying the EVMS data through the 3D model.

In FIGS. 12 and 13, the network 400 includes at least one promised between the EVMS 100, the integrated management server 200, and the user device 400 in a wired network environment and a wireless communication network environment.

For example, a web-based wireless connection). The connection between the integrated management server 200 and the user device 300 may be wirelessly connected (eg, web-based wireless connection) by a wireless network using a wireless communication technology.

On the other hand, the present invention relates to the construction of a web-based 3D process / cost management system linked to the EVMS 100 for a specific construction site. Therefore, in order to apply the present invention, as described above, first, EVMS data configured in the field may be preset in the EVMS 100. A 3D model needs to be generated for 3D process simulation, which is expressed as 4D, and a 5D system connecting the 3D model and cost can be constructed. The configuration for the integrated management of the process and the cost using the web-based 3D modeling in the integrated management system of the present invention, that is, the EVMS linkage step 60 shown in FIG. 1 will be described with reference to FIG. 15.

15 is a view illustrating an interworking structure between the EVMS 100 and the integrated management server 200 according to FIGS. 12 to 14, and FIG. 16 illustrates an example in which EVMS data is extracted in the form of an electronic document in the present invention. Figure is shown. In detail, FIG. 15 illustrates an example of a structure in which the EVMS 100 receives process data and cost data as a web service and associates with the 3D simulator.

As described above, the present invention uses a 3D model divided into simulation units and codes of EVMS data such as activity information (common information) 110, process information 120, and cost information 130 of the EVMS 100. Implement auto-association by matching activity codes. Therefore, the EVMS data is interworked in an electronic document format (eg, XML format) using a web service.

For example, the integrated management server 200 may transmit a request including a user ID and a password that can access the EVMS 100 through a web service. Then, the EVMS 100 provides a response in an electronic document format (for example, XML format) including data required in the course of construction through the web service.

In this case, the list of data to be loaded from the EVMS 100 may be arranged as shown in the following <Table 1>.

As shown in Table 1, first, the activity information (common information) 110 may have an activity ID, an activity name, a sub activity code, and a sub activity name. The activity code is matched with the 3D model for each member and automatically linked when setting data in the program.

In addition, the activity code input during the 3D modeling process can be linked with the information of Level 6 or Level 7 representing the site information in the WBS of the EVMS data. That is, since the EVMS 100 is a system in which the process information 120 and the cost information 130 are linked, the EVMS 100 may automatically calculate the cost when the performance is input on a schedule. In addition, the estimated amount, the actual input amount, and the remaining amount that is the difference between the two amounts may be included in the cost information 130. At this time, all the amounts may use the contract reference amount. As such, the example in which the EVMS data of the EVMS 100 is extracted in the form of an electronic document (eg, XML) may be represented in the form of an XML document for web-based as shown in FIG. 16.

Can be managed by In addition, the WBS management unit 210 defines the scope and type of basic data related to construction, process, and cost based on web-based 3D model data (internet model) linked with EVMS data, and defines the hierarchical structure of each process. Can be divided and managed. That is, the WBS management unit 210 may define the range and type of the basic data related to the construction and the process to efficiently create and operate the process plan.

The PBS management unit 230 associates the WBS code information provided by the WBS management unit 210 with the project information provided by the project management unit 250 (particularly, web-based 3D model data (internet model)) to manage process and process rate. It is responsible for managing code, and simulation code. The PBS management unit 230 systematically manages the final structure, which is a standard of work classification and management for performing construction (project).

The PBS management unit 230 may support 3D information management and 3D detail management through the site information of the structure according to 3D modeling based on the information provided from the WBS management unit 210, the project management unit 250, and the simulation unit 270.

The simulation unit 270 provides a simulation function based on web-based 3D model data. The simulation unit 270 may simulate the progress of the structure according to the process in the PBS management unit 230 based on the WBS code information, and may share the simulation code information with the PBS management unit 230.
