<Overview of Embodiments of the Present Invention>

  In BIM (Building Information Modeling) used in design and construction planning of a building, a BIM model, which is a three-dimensional model representing a building, is generated on a computer. When creating a design and construction plan using BIM, each of a plurality of functions prepares a BIM model according to their function, and creates a design and construction plan of a building by linking the BIM models.

  The BIM model includes shape information representing the shape of each element of the building and attribute information of each element of the building. For example, an object of "door" which is an element included in a building is represented in a predetermined shape. Further, the object name “door” is given to the object of “door” which is an element included in the building, and information such as “dimension” and “material” is further given as attribute information.

  FIG. 1 shows a conceptual diagram of a design and construction plan using a BIM model. FIG. 1 shows, as an example of each BIM model, a building design model, a structural design model, a facility design model, an integration model, a construction plan model, a construction model, a steel frame model, a facility construction model, and an FM (Facility Management) model. It is done. In addition, the BIM model generated at the time of construction of a building is various, and the above-mentioned BIM model is shown in the example of FIG.

  The basic requirement model shown in FIG. 1 is a BIM model determined from information on the requirements of the builder. The basic requirement model is provided with shape information representing the shape of each element of the building and attribute information of each element of the building, which are determined from the information on the requirements of the owner of the building.

  Each BIM model shown in FIG. 1 is created by each function. For example, a building design model as an example of a BIM model is created by a function in charge of building design. In addition, when each function creates its own BIM model, it refers to the basic requirement model. Each function creates a BIM model with reference to the basic requirement model to generate a plurality of BIM models satisfying the requirements of the owner.

  It is necessary to check whether the BIM models created by each function are consistent among the BIM models. For example, checking whether the beam can be accommodated in the ceiling between the architectural design model and the structural design model, checking whether the piping facility can be accommodated in the ceiling between the architectural design model and the facility design model, and It is necessary to check whether the piping hits a column between the structural design model and the equipment design model.

  Therefore, the BIM model inspection support system according to the present embodiment superimposes each of the plurality of BIM models, and outputs inspection information on the superposition of the plurality of BIM models. In this embodiment, a BIM model inspection support system including a plurality of client terminals and a server realizes a superposition platform of BIM models.

  FIG. 2 shows a conceptual view of the superposition platform of the present embodiment. In the example of FIG. 2, a site model, a basic plan model, a basic design model, a detailed design model (architecture), a detailed design model (structure), a detailed design model (equipment), a construction model (frame), a construction model (exterior), A construction model (equipment), a construction model (interior), a completion model, and an FM model are shown.

  As shown in FIG. 2, when each BIM model is generated, the basic requirement model is referenced. Each function refers to the basic requirement model to create a BIM model that meets the requirements of the owner. Then, the superposition of each BIM model is performed in the superposition platform by the BIM model inspection support system. This makes it possible to properly check whether the BIM models match each other.

  FIG. 3 shows a conceptual diagram of the BIM model inspection support system of the present embodiment. As shown in FIG. 3, in the present embodiment, a plurality of BIM models created by a plurality of functions are transmitted to a server operated by the overlapping functions. Then, a plurality of BIM models are overlaid by the server operated by the overlay function, and inspection information regarding the overlay is transmitted to the client terminal of each function. For example, as shown in FIG. 3, the inspection information related to the overlay includes a point K at which a mismatch occurs between the BIM models.

  Thereby, each function, such as design and construction, can confirm whether or not the BIM model created by itself is consistent with other BIM models (including the basic requirement model). Therefore, the design and construction plan of the building can be appropriately and efficiently created.

  Hereinafter, embodiments of the present invention will be described in detail.

<System configuration of BIM model inspection support system>

  As shown in FIG. 4, the BIM model inspection support system 10 includes a plurality of client terminals 12 and a server 14 used by each of a plurality of functions. The plurality of client terminals 12 correspond to a plurality of functions, and each function creates a BIM model using its own client terminal 12.

  The plurality of client terminals 12 and the server 14 are connected via a network 16 such as the Internet or a LAN, for example.

[Client terminal]

  FIG. 5 is a block diagram showing an example of the configuration of the client terminal 12. The client terminal 12 includes a central processing unit (CPU), a read only memory (ROM) storing a program for realizing each processing routine, a random access memory (RAM) temporarily storing data, and a storage unit. A memory, a network interface and the like are included. The client terminal 12 can be functionally represented by a configuration including the operation unit 120, the computer 122, and the display unit 130 as shown in FIG.

  The operation unit 120 receives operation information input from a user who is a professional. The operation unit 120 is, for example, a keyboard or a mouse. Specifically, each function inputs the design information of the building from the operation unit 120.

  The computer 122 functionally includes, as shown in FIG. 5, a BIM model generation unit 124, a BIM model storage unit 126, and a transmission / reception unit 128.

  The BIM model generation unit 124 generates a BIM model based on the design information received by the operation unit 120.

  Each function operates the BIM model generation unit 124 according to the operation by the operation unit 120, and creates a BIM model according to its own function. When creating a BIM model, each function presets a reference cube in the space of the BIM model as an example of reference information on superposition.

  When superimposing a plurality of BIM models, it is necessary to match the coordinate system of each BIM model. Therefore, in the present embodiment, when creating each of a plurality of BIM models, a reference cube is set for each BIM model.

  FIG. 6 shows an explanatory diagram for describing a reference cube regarding superposition. For example, as shown in FIG. 6, each function sets a cube corresponding to reference information on superposition at a specific location in the space where the BIM model BM is created. Since the space in which the BIM model BM is created is three-dimensional, for example, a cube of 1 m × 1 m × 1 m is set as reference information. For example, as shown in FIG. 6, a 1-m cube having 1 FL as a vertex on the side opposite to the 10-m point from the intersection of A-way and 1-way is preset for each space of a plurality of BIM models.

  The BIM model storage unit 126 stores the BIM model generated by the BIM model generation unit 124 according to the operation of the function.

  The transmitting and receiving unit 128 transmits and receives information to and from the server 14. Specifically, the transmission / reception unit 128 transmits the BIM model stored in the BIM model storage unit 126 to the server 14 via the network 16 in accordance with the operation input to the operation unit 120. The transmitting and receiving unit 128 also receives the examination information transmitted from the server 14. The examination information will be described later.

[server]

  The server 14 includes a CPU, a ROM storing a program for realizing each processing routine, a RAM temporarily storing data, a memory as a storage unit, a server including a network interface, and the like. The server 14 can be functionally represented by a configuration including the operation unit 140, the computer 141, and the display unit 150, as shown in FIG.

  The server 14 is operated by an overlapping function which is a function different from the design function and the installation function and which is in charge of overlapping the plurality of BIM models.

  The operation unit 140 receives operation information input from the overlapping function. The computer 141 executes each process according to the operation information received by the operation unit 140.

  The computer 141 functionally includes, as shown in FIG. 7, a transmitting / receiving unit 142, an overlapping unit 144, and a multiple model storage unit 146.

  The transmission and reception unit 142 transmits and receives information to and from the client terminal 12. Specifically, the transmitting and receiving unit 142 receives, via the network 16, a plurality of BIM models transmitted from the client terminal 12 by the operation of each function. Then, the transmitting and receiving unit 142 stores the received plurality of BIM models in the multiple model storage unit 146.

  The multiple model storage unit 146 stores multiple BIM models transmitted from multiple client terminals 12. The basic requirement model is also stored in the multiple model storage unit 146.

  The basic requirement model is, for example, stored in the multiple model storage unit 146, and is sequentially updated according to the information transmitted from the client terminal 12 of each function. Specifically, when creating a BIM model according to one's own ability, each ability reflects the building information determined from the information representing the requirements of the building owner on the basic requirement model. This generates a basic requirements model. Also, each function refers to each information obtained from the basic requirement model to generate a BIM model according to the function.

  The superposition unit 144 acquires the operation information received by the operation unit 140. Then, when the operation information input by the overlapping function is operation information related to the execution of overlapping, the plurality of BIM models stored in the multiple model storage unit 146 are acquired. Then, the superposition unit 144 superimposes each of the acquired plurality of BIM models, and outputs inspection information on superposition of the plurality of BIM models.

  Specifically, the superposition unit 144 superimposes each of the plurality of BIM models so as to match the reference cubes included in the plurality of BIM models. As a result, since a plurality of BIM models can be appropriately superimposed, it is possible to identify a mismatch, an interference location, and the like between each BIM model.

  Attribute information is given to each element (object) included in each BIM model. The attribute information assigned to the object includes attribute information indicating what the object is. For example, information such as whether the object is a pillar or a pipe is given as attribute information. Therefore, the superposition unit 144 generates inspection information based on the attribute information given to each object of the plurality of BIM models and the shape information indicating the shape of each object of the plurality of BIM models. For example, inspection information is generated as to whether or not the column as the object and the pipe interfere with each other.

  In the present embodiment, when a plurality of BIM models are superimposed, the plurality of BIM models are simply superimposed without integrating the BIM models.

  For example, when checking whether a plurality of BIM models match, it is conceivable to combine a plurality of BIM models into one integrated model. In this case, a location such as interference is identified in the integrated model, and a correction operation is performed on the particular location.

  However, multiple BIM models are constantly changing as they are created by each function. Therefore, each BIM model is updated by each function while modifying the integrated model. For this reason, it is not appropriate to modify the integrated model after generating the integrated model from multiple BIM models.

  So, in this embodiment, when superimposing a plurality of BIM models, it superimposes without integrating each BIM model, and generates inspection information about superposition. Thereby, even when each BIM model is updated by each function, it is possible to appropriately check a plurality of BIM models.

  Then, the superposition unit 144 transmits inspection information on superposition to each client terminal 12 via the transmission / reception unit 142.

  The display unit 150 displays the information output from the computer 141 to, for example, the overlapping function who is the user of the server 14. For example, the display unit 150 can display examination information related to overlaying in accordance with the operation information received by the operation unit 140.

<Operation of BIM model inspection support system>

  Next, the operation of the BIM model inspection support system 10 will be described with reference to FIG.

  First, in step S10, each client terminal 12 is operated by each function. Then, the operation unit 120 receives the design information input from the professional. The BIM model generation unit 124 generates a BIM model based on the design information received by the operation unit 120. Then, the BIM model is stored in the BIM model storage unit 126.

  In step S12, when the operation unit 120 of each client terminal 12 receives BIM model transmission instruction information input from the function, the transmission / reception unit 128 transmits the BIM model stored in the BIM model storage unit 126 in step S10. Is sent to the server 14.

  In step S14, the transmission / reception unit 142 of the server 14 receives each of the BIM models transmitted from each client terminal 12 in step S12. Then, the transmitting and receiving unit 142 of the server 14 stores each of the BIM models transmitted from each client terminal 12 in the multiple model storage unit 146.

  In step S <b> 16, when the operation unit 140 inputs operation information regarding the execution of superposition, the superposition unit 144 acquires a plurality of BIM models stored in the plurality of model storage units 146.

  In step S18, the superposition unit 144 superimposes each of the plurality of BIM models so as to match the reference cubes for superposition included in the plurality of BIM models acquired in step S16. The superposing unit 144 then performs inspection information based on the attribute information attached to each object of the plurality of BIM models acquired in step S16 and the shape information indicating the shape of each object of the plurality of BIM models. Generate

  In step S <b> 20, the transmitting and receiving unit 142 transmits the examination information generated in step S <b> 18 to each client terminal 12.

  In step S22, the transmitting and receiving unit 128 of each client terminal 12 receives the examination information transmitted from the server 14 in step S20.

  In step S24, the display unit 130 of each client terminal 12 displays the examination information received in step S22.

  Each function confirms the examination information displayed on the display unit 130 and corrects its own BIM model.

  As described above in detail, in the present embodiment, a plurality of BIM models that are three-dimensional models representing buildings are acquired, and each of the acquired plurality of BIM models is superimposed, and the superposition of the plurality of BIM models is related. Output inspection information. Thus, when there are a plurality of BIM models related to a building, it is possible to appropriately support the inspection as to whether or not the plurality of BIM models match.

  Further, in the present embodiment, inspection information is generated based on attribute information attached to each object of a plurality of BIM models and shape information indicating the shape of each object of a plurality of BIM models. This makes it possible to appropriately check whether objects of a plurality of BIM models are consistent. For example, it can be checked whether or not a column which is an example of a structure and a pipe which is an example of an installation interfere with each other.

  Also, in the present embodiment, each of the plurality of BIM models is created based on a preset reference cube regarding superposition. And inspection information is generated based on a reference cube about superposition. Specifically, inspection information between a plurality of BIM models is generated by matching reference cubes for superposition, which are present in each of the plurality of BIM models. Overlaying can be performed appropriately by overlaying multiple BIM models so that the reference cubes for overlaying coincide. Thereby, inspection information regarding superposition can be generated appropriately.

  Further, in the present embodiment, the BIM model is a BIM model in which shape information representing the shape of each object of the building and attribute information of each object of the building are added to the plurality of BIM models as determined from the information on the requirements of the building owner. Includes a requirements model. By including the basic requirement model in the BIM model to be superimposed, it is possible to appropriately check whether each of the plurality of BIM models meets the requirements of the owner.

  Further, in the present embodiment, the server 14 is operated by the overlapping function which is a function different from the design function and the installation function and which is in charge of the overlapping operation of the BIM model. The superposition work can be efficiently performed by taking charge of the superposition work of a plurality of BIM models. Further, the overlapping functions can perform overlapping operations in an independent position, and the inspection information that is the overlapping result can be made known to all persons involved including the design function and the installation function. In addition, when the overlaying functions perform the overlaying work, the responsibility for creating and correcting each BIM model can be each function.

  Further, as shown in FIG. 9, the overlapping work by the overlapping function may be repeatedly performed in each stage of planning, design, construction and FM of one building.

  In this case, first, in step S1, each function such as design and construction operates each client terminal 12 to create a BIM model according to its function. Then, each function such as design and construction operates each client terminal 12 to transmit the BIM model created by itself to the server 14.

  Next, in step K1, the overlay function operates the server 14 to overlay each of the plurality of BIM models created by each function to generate inspection information on overlay. Then, the server 14 transmits inspection information on superposition to each client terminal 12. In addition, in step K2, the overlaying function performs an interference check between each BIM model based on the inspection information on the overlaying.

  In step SK1, the superposition function sets a superposition study meeting. In this superposition study meeting, each function such as design and construction and the superposition function participate, and each BIM model is examined based on inspection information on superposition.

  In step K3, based on the examination result of the superposition study meeting in step SK1, the superposition work prepares a report summarizing the examination result and distributes it to each work.

  In step S2, each function, such as design and construction, confirms the interference location of its own BIM model based on the report distributed in step K3 and performs feedback on the BIM model. Then, in step S1, each function such as design and construction continues to create its own BIM model.

  The cycle shown in FIG. 9 is periodically carried out at each stage of planning, design, construction and FM of one building. As a result, it is possible to early find an inconsistent position among a plurality of BIM models, and to correct each BIM model appropriately. Therefore, a plurality of BIM models can be created concurrently (parallel). Also, for example, even in the design stage, the construction model can be launched early.

  In addition, the meeting time can be shortened, the construction drawing correction time can be reduced, the number of man-hours can be reduced, and rework and rework can be reduced. In addition, decision-making and consensus-building can be smoothly promoted.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made without departing from the scope of the present invention.

  For example, although the case where the server 14 is operated by the overlapping function has been described as an example in the above embodiment, the present invention is not limited to this. For example, the overlay function operates one client terminal 12, and the server 14 overlays a plurality of BIM models according to the operation information transmitted from the client terminal 12 operated by the overlay function, and checks Information may be output.

  Further, the superposition unit 144 may set a BIM model to be superimposed according to the operation information received by the operation unit 140. For example, the superposition unit 144 may set a structural design model and an equipment design model among a plurality of BIM models, and confirm the consistency between the structural design model and the equipment design model.

  In addition, the overlapping unit 144 may set a specific part to be overlapped according to the operation information received by the operation unit 140. For example, the superimposing unit 144 may set a first floor portion of the BIM model, superimpose a plurality of BIM models at that portion, and generate inspection information on superposition.

  Further, the overlapping unit 144 may set an object that is an element of a building to be overlapped. For example, the overlapping unit 144 may set the pipe and the column as objects to be overlapped, and may generate inspection information on the overlapping between the objects. This makes it possible to easily check the interference between the pipe and the pillar if it is desired to check for any reason.
