The following embodiments generally relate to integrated data generation systems, construction plan management systems, integrated data generation methods, construction plan management methods, and programs. More specifically, the following embodiments relate to an integrated data generation system, construction plan management system, integrated data generation method, construction plan management method, and program using a three-dimensional model of a building.

(1) Overview In general, there are three types of construction work for buildings: A construction, B construction, and C construction. Construction A is construction carried out by a contractor designated by the building owner (lessor) at the expense of the building owner. B construction is construction that is paid for by the lessee of the building and executed by a contractor designated by the owner. In addition, C construction is construction that is paid for by the borrower and executed by a contractor designated by the borrower.

In recent years, the use of BIM (Building Information Modeling), which includes 3D models of buildings, is progressing from the design and design stage, mainly for construction related to skeletons (building structures), which is A construction. On the other hand, the construction of C construction and the construction related to infill (interior, equipment), which is downstream of the construction process among A construction, is mainly done with the experience of site supervisors or specialist contractors, and the use of digital technology such as BIM. is not progressing.

In the C construction and the infill-related construction of the A construction, compared to the skeleton-related construction of the A construction, where the standardization of the process is progressing, there are more types of equipment to handle, and the construction method also depends on the know-how of the workers. . In addition, there are various combinations of elements for each construction site and each project. In addition, the degree of progress of construction work at the construction site and changes due to workers occur every day, and it is necessary to make detailed changes according to the progress of construction work. In addition, there are few on-site personnel who can handle BIM-related technology, which requires advanced skills. Due to these factors, it was difficult to standardize the process in the C construction and the infill-related construction of the A construction, and it was difficult to utilize digital technology such as BIM for work at the construction site. In addition, it is difficult for manufacturers who develop equipment to accumulate data on construction, which is one of the factors that make it difficult to develop new equipment products and solutions that lead to construction savings.

Therefore, in this embodiment, even if it is C construction and A construction related to infill, an integrated data generation system that can manage the construction process using a three-dimensional model of the building, a construction plan management system, An integrated data generation method, a construction plan management method, and a program will be described.

The construction plan management system of this embodiment manages a construction plan for construction of a building. Construction of buildings includes various construction works performed in renovation of buildings (remodeling, renovation, remodeling, extension, etc.) and new construction of buildings. In addition, the building may be a detached house, collective housing, factory, store, office, office building, or various facilities. The size and shape are not limited. Moreover, the content of the construction may be construction related to building construction, such as construction work, electrical work, water supply and drainage work, and civil engineering work. Examples of building construction include construction of office lighting equipment, air conditioning equipment, and ventilation equipment, interior construction, power line wiring construction, information wiring construction, wireless construction, and building management system installation construction.

A construction plan management system A1 shown in FIG. The integrated data generation system 2 includes a linking unit 21 , an integrated data generation unit 22 , a communication unit 23 , a communication unit 24 , an integrated data acquisition unit 25 and a storage unit 26 .

Each function of the measurement unit 1, the linking unit 21, the integrated data generation unit 22, and the communication unit 23 described above is preferably realized by a portable information terminal B1 such as a tablet terminal or a smartphone. The information terminal B1 is an information terminal managed by a contractor such as a building contractor or a designer, and is operated by the contractor. An operation of the information terminal B1 (hereinafter referred to as a terminal operation) is performed on an operation unit such as a touch panel display, a keyboard, and a voice recognition device of the information terminal B1.

The information terminal B1 has a computer system. Some or all of the functions of the measurement unit 1, the linking unit 21, the integrated data generation unit 22, and the communication unit 23 are realized by the computer system executing the program. A computer has a processor that operates according to a program as a main hardware configuration. Any type of processor can be used as long as it can implement functions by executing a program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or LSI (large scale integration). Here, they are called ICs and LSIs, but they may be called system LSIs, VLSIs (very large scale integration), or ULSIs (ultra large scale integration) depending on the degree of integration. A field programmable gate array (FPGA), which is programmed after the LSI is manufactured, or a reconfigurable logic device capable of reconfiguring the junction relationships inside the LSI or setting up circuit partitions inside the LSI for the same purpose. can be done. A plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. A plurality of chips may be integrated into one device, or may be provided in a plurality of devices. The program is recorded in a non-temporary recording medium such as a computer-readable ROM, optical disk, hard disk drive, or the like. The program may be pre-stored in a non-temporary recording medium, or may be supplied to the non-temporary recording medium via a wide area network including the Internet.

Each function of the communication unit 24, the integrated data acquisition unit 25, the storage unit 26, the data processing unit 3, and the data output unit 4 described above is preferably realized by, for example, the server device C1. The server device C1 is configured to be able to communicate with the information terminal B1 via a communication network NT1 including the Internet. In addition, the server device C1 is managed by either a contractor such as a building contractor or a designer, or a management company of the construction plan management system A1.

The server device C1 includes a computer system. Some or all of the functions of the communication unit 24, the integrated data acquisition unit 25, the storage unit 26, the data processing unit 3, and the data output unit 4 are implemented by the computer system executing the program.

It is preferable that the measurement unit 1 creates a three-dimensional model of the whole or a part of the building based on the images of the interior and exterior of the building captured by the camera of the information terminal B1. In addition to the floor plan of the building, the 3D model includes furniture such as desks and bookshelves in each room, lighting fixtures, air conditioners, ventilation fans, air valves, fire alarms, televisions, wiring devices and other facilities, doors , and windows, etc. are reflected. The measurement unit 1 can also create a three-dimensional model including not only the building but also the site by capturing an image of the site where the building is built with the camera provided in the information terminal B1. The building to be imaged may be a building before or in the middle of renovation, or a building under new construction.

The measurement unit 1 is implemented by, for example, the information terminal B1 executing an application for creating a three-dimensional model. At the construction site, it is difficult to carry around a high-performance personal computer capable of executing BIM software or the like, so an information terminal B1 such as a tablet terminal or a smart phone that is easy to carry is used. For this reason, the three-dimensional model of the building created by the measurement unit 1 has a relatively small data volume. A three-dimensional model may also be created by using an acceleration sensor or a gyro sensor included in the information terminal B1 together with a camera.

In addition, the measurement unit 1 may create a three-dimensional model using a LiDAR (light detection and ranging) or a three-dimensional laser scanner that is separate from the information terminal B1.

FIG. 2 shows a three-dimensional model M1 as an example of a three-dimensional model. The three-dimensional model M1 is composed of a room model M11, an element model M12, and the like. The room model M11 is a three-dimensional model of a room in the building. The element model M12 is a three-dimensional model of elements such as members that make up the room and equipment installed in the room. The members are building materials, piping, wiring, and the like. Equipment includes equipment such as lighting fixtures, air conditioners, ventilation fans, air valves, fire alarms, televisions and wiring fixtures, wiring, fixtures such as desks and bookshelves, doors, and windows.

The integrated data generation system 2 includes a linking unit 21 and a storage unit 26 as main components. The linking unit 21 links a work object including information on work to be performed during construction of the building to a target area corresponding to a part of the building in the three-dimensional model representing the three-dimensional shape of the building. The storage unit 26 stores integrated data including at least three-dimensional model data in which the work object is linked to the target area.

For example, in FIG. 2, two target areas 9 are set in the three-dimensional model M1. One target area 9 is an element target area 91 corresponding to the element model M12, and corresponds to elements such as equipment and members. The other area of interest 9 is a spatial area of interest 92 corresponding to a space within the building (corner, center, top or bottom of a room, etc.). Hereinafter, the target area 9 corresponding to the element is sometimes referred to as an element target area 91 and the target area 9 corresponding to the space inside the building is sometimes referred to as a spatial target area 92 . Each of the target areas 9 is associated with a work object including information on work to be performed during construction of the element.

The construction plan management system A1 includes a construction plan creation unit 31 and a data output unit 4 as main components. The construction plan creation unit 31 creates a construction plan for the building based on the integrated data. The data output unit 4 outputs construction plan data to the output device 5 .

The output device 5 is a tablet terminal, a smart phone, a personal computer, or the like having a display device, receives construction plan data from the data output unit 4, and displays the construction plan data on the display device. The display device is a liquid crystal display device, an organic EL display device, or the like. A display device is basically used as the output device 5, but a printer may also be used.

The integrated data generation system 2 described above generates integrated data including at least three-dimensional model data in which the work object is linked to the target area 9 , and stores the integrated data in the storage unit 26 . By storing the integrated data, the integrated data generation system 2 can manage the construction process using the three-dimensional model of the building.

The construction plan management system A1 can also manage the construction process using the three-dimensional model of the building by creating and outputting construction plan data based on the integrated data.

(2) Integrated Data Generation System The integrated data generation system 2 includes a linking unit 21 , an integrated data generation unit 22 , a communication unit 23 , a communication unit 24 , an integrated data acquisition unit 25 and a storage unit 26 . Then, the integrated data generation system 2 performs each process of the three-dimensional model acquisition step S1, the linking step S2, the integrated data creation step S3, and the storage step S4 shown in the flowchart of FIG.

(2.1) 3D Model Acquisition Step First, in a 3D model acquisition step S<b>1 , the integrated data generator 22 acquires the data of the 3D model representing the 3D shape of the building from the measurement unit 1 .

In the three-dimensional model acquisition step S1, the integrated data generation unit 22 may acquire three-dimensional model data converted from the two-dimensional drawing data of the building. In the case of the A construction, the integrated data generation unit 22 may acquire a three-dimensional model of the building created by a prime contractor such as a general contractor.

(2.2) Tying Step Next, in a tying step S2, the tying unit 21 ties the work object to the target area of the three-dimensional model. The processing in the linking step S2 will be described in detail below.

(2.2.1) Target Area The linking unit 21 displays the three-dimensional model data that the integrated data generating unit 22 has acquired from the measuring unit 1 on the display of the information terminal B1. The display form of the three-dimensional model on the display of the information terminal B1 may be either a perspective view or a floor plan (plan view), and it is preferable that the display form can be switched by operating the terminal.

For example, FIG. 4 shows a floor plan of a three-dimensional model M2 displayed on the display G1 of the information terminal B1. The three-dimensional model M2 includes a structure model M20, room models M21-M24, an element model M26, and a site model M27. The site model M27 is a three-dimensional model of the site on which the building is built. The structure model M20 is a three-dimensional model of the exterior structure of the building. The room models M21-M24 are three-dimensional models of each room of the building. The element model M26 is a three-dimensional model of the elements of the building.

When the element model M26 is selected as the target area 9 by terminal operation, the linking unit 21 automatically creates the element target area 91 corresponding to the element model M26. Then, the associating unit 21 associates the element target area 91 with the work object including the information of the work performed during construction of the building.

Further, the linking unit 21 creates a spatial target area 92 corresponding to the space of the three-dimensional model M2 as the target area 9 by operating the terminal. If the display G1 is a touch panel display, the spatial target area 92 is set by performing an operation such as tapping, pinching, or dragging with a finger or the like on the surface of the display G1. Then, the linking unit 21 links the work object to the spatial target area 92 .

(2.2.2) Work Object The linking unit 21 links the target area 9 with the work object OA shown in FIG. The work object OA is an object having a data structure that has "work type", "work position", and "work time" as attributes, and information can be set for each attribute. The work object OA in FIG. 5 is in an unset state in which information is not set for each attribute.

The work objects OA include a first work object OA1 linked to the element target area 91 described above and a second work object OA2 linked to the spatial target area 92 described above.

The linking unit 21 sets element-specific information included in an element object OB, which will be described later, to each attribute of the first work object OA1.

The linking unit 21 sets information corresponding to the terminal operation to each attribute of the second work object OA2. For each attribute of the second work object OA2, information corresponding to the content, scale, range, etc. of the construction involved in building construction is set by terminal operation. For example, working hours are preferably standard working hours for one worker. Specifically, if the work type is transportation, the standard work time per 1 m transportation distance by one worker is used. Alternatively, the work time may be a time obtained by adding an additional time to the standard work time in consideration of individual differences of workers.

Also, in order to make the contents of the work object OA easy to understand, it is preferable to set a name, icon, etc. for the work object OA.

(2.2.3) Element Objects FIG. 6 illustrates element models M261-M264 as four element models M26 that the three-dimensional model has. Element models M262 and M263 are arranged on the upper surface of the element model M261, and the element model M262 and the element model M263 are connected by an element model M264. In this case, the element model M261 is a three-dimensional model of the member P1 such as the base material. The element model M262 is a three-dimensional model of the facility P2 such as electrical equipment. The element model M263 is a three-dimensional model of the facility P3 such as electrical equipment. The element model M264 is a three-dimensional model of the member P4 such as wiring.

The element model M26 includes element objects OB in which element-specific information is set in advance. The element-by-element information is information on work that targets an element.

The element object OB has "element object name", "work position", "work type" and "work time" as attributes, and the information set in each attribute corresponds to element-specific information. The name of the element corresponding to the element object OB is set as element-specific name information in the attribute "element object name" of the element object OB. In the attribute "work position" of the element object OB, the element target area 91 of the element model M26 corresponding to the element object OB is set as element-specific position information. In the attribute "work type" of the element object OB, the type (name) of the work performed on the element model M26 during construction of the building is set as the element-by-element type information. The types of work include, for example, "transportation", "wiring", "piping", "preparation for assembly", "assembly", and "inspection". The time required for the work set in the "work type" is set as element-specific time information in the attribute "work time" of the element object OB. Note that the element object OB may have one set of attributes "work type" and "work time", or may have a plurality of sets of attributes "work type" and "work time". .

FIG. 7 shows element objects OB1-OB4, which are element objects OB of element models M261-M264. The element object OB1 of the element model M261 has the member P1 set in the "element object name", the target area 921 set in the "work position", and the respective information in the set of "work type" and "work time". is set. The element object OB2 of the element model M262 has the facility P2 set in the "element object name", the target area 922 set in the "work position", and the respective information in the set of "work type" and "work time". is set. The element object OB3 of the element model M263 has the facility P3 set in the "element object name", the target area 923 set in the "work position", and the respective information in the set of "work type" and "work time". is set. The element object OB4 of the element model M264 has the member P4 set in the "element object name", the target area 924 set in the "work position", and the respective information in the set of "work type" and "work time". is set.

(2.2.4) Linking The linking unit 21 assigns work objects OA (first work object OA1, second work object OA2) to each of the target areas 9 (element target area 91, spatial target area 92). Tie

(first work object)
When the work object model OM (see FIG. 8), which is the model of the first work object OA1, overlaps with the element model M26 of the three-dimensional model displayed on the display G1 of the information terminal B1 by the user's terminal operation, the linking unit 21 sets the element object OB1 of the element model M26 to the first work object OA1. The work object model OM is displayed on the display G1, and is moved within the display G1 by performing an operation such as dragging with a finger or the like on the display G1. In FIG. 8, the user moves the work object model OM to superimpose the work object model OM on the element model M261. The process of superimposing the work object model OM on the element model M26 corresponds to the process of pasting the first work object OA1 onto the element model M26.

In this case, the linking unit 21 sets (overwrites) the element-specific information of the element object OB1 of the element model M261 to the first work object OA1 of the work object model OM, as shown in FIG. 9A. Specifically, the linking unit 21 links the element-specific information of the work position, work type, and work time of the element object OB1 to the attributes "work position," "work type," and "work time" of the first work object OA1. , respectively. FIG. 9B shows the first work object OA1 set with the element-specific information of the element object OB1. The first work object OA1 is linked to the target area 9 by the information of the element target area 91 set to the attribute "work position".

The linking unit 21 preferably determines whether or not the element-specific information set in each attribute of the element object OB1 is suitable for the first work object OA1. If the linking unit 21 determines that the element-specific information matches the first work object OA1, it sets the element-specific information of the element object OB1 to each attribute of the first work object OA1. Specifically, the linking unit 21 compares each attribute of the element object OB1 with each attribute of the first work object OA1, and assigns the element-specific information corresponding to the attribute of the first work object OA1 to the first work object. Set to OA1. The linking unit 21 does not set element-specific information that does not correspond to the attribute of the first work object OA1 to the first work object OA1.

(second work object)
The linking unit 21 links the second work object OA2 to the spatial target area 92 (see FIG. 4) of the three-dimensional model displayed on the display G1 of the information terminal B1 by the user's terminal operation. FIG. 10 shows the second work object OA2 with information set in each attribute. Information is set in the attributes "work position", "work type", and "work time" of the second work object OA2 by the user's terminal operation. A spatial target area 92 is set in the attribute "work position" of the second work object OA2. The attribute "work type" of the second work object OA2 is set with the type (name) of the work performed on the spatial target area 92 during construction of the building. The types of work include, for example, "dismantling", "dismantling and transportation", "marking", and "cleaning". The attribute "work time" is set with the time required for the work set in the "work type".

(2.3) Integrated Data Creation Step In the integrated data creation step S3, the integrated data generation unit 22 associates the three-dimensional model created by the measurement unit 1 with the target area 9 of the three-dimensional model created by the association unit 21. Generate integrated data based on the work object OA.

The integrated data generation unit 22 of the present embodiment converts the data format of the three-dimensional model associated with the work object OA to 3D (three dimensions) data in a specific data format or building information modeling (Building Information Modeling) data ( BIM data), and the converted data is used as integrated data. In addition, since BIM data has a higher degree of freedom in setting attribute information and real-time performance, it is preferable to use BIM data as the integrated data.

The data format of the three-dimensional model created by the measurement unit 1 is a general-purpose data format with extensions such as csv, json, xml, yaml, and dxf. An API (Application Programming Interface), for example, is used to convert the three-dimensional model data in such a general-purpose data format into BIM data. Alternatively, it is also possible to convert to BIM data using a web application on the server.

Note that the integrated data generation unit 22 may use data in which the three-dimensional model created by the measurement unit 1 is associated with the work object OA as integrated data without converting the data format. That is, the integrated data may be data including the three-dimensional model created by the measurement unit 1 and the work object OA linked to the target area 9 of the three-dimensional model by the linking unit 21 .

(2.4) Communication Unit, Integrated Data Acquisition Unit, and Storage Unit The communication unit 23 of the information terminal B1 and the communication unit 24 of the server device C1 are configured to be able to communicate with each other via the communication network NT1 including the Internet. there is

The communication unit 23 of the information terminal B1 transmits the integrated data generated by the integrated data generation unit 22 to the server device C1 via the communication network NT1.

In the server device C1, the communication section 24 receives various data transmitted via the communication network NT1. The integrated data acquisition unit 25 of the server device C1 extracts integrated data from various data received by the communication unit 24 and stores the extracted integrated data in the storage unit 26 . That is, the storage unit 26 functions as a database that stores integrated data.

By storing the integrated data, the integrated data generation system 2 can manage specific work at the construction site and construction processes such as schedules. In other words, the integrated data generation system 2 can manage the construction process using the three-dimensional model of the building. That is, the integrated data generation system 2 associates the work object OA with the target area 9 of the three-dimensional model of the building to be constructed at each time point before and during the construction of the building. Information related to work can be digitized and centrally managed. As a result, the integrated data generation system 2 can realize simplification of data management, and can also achieve commonality of data management among a plurality of departments.

In addition, if the integrated data is BIM data, in addition to the three-dimensional model of the building, the work object OA, and the element object OB, the construction schedule, construction labor resources, construction cost, pre-construction planning, and construction Other information about merchants, etc. is also facilitated to be included in the integrated data.

(3) Construction Plan Management System The construction plan management system A1 includes a measurement unit 1, an integrated data generation system 2, a data processing unit 3, a data output unit 4, and an output device 5. The data processing section 3 includes a construction plan creating section 31 and a feedback section 32 . Then, the construction plan management system A1 performs the processing of steps S11 to S22 shown in the flowchart of FIG. For example, in the construction work of C construction, the site agent often conducts site surveys and prepares schematic construction drawings and construction plans, and the CAD operator in the office is in charge of drafting. Examples of C construction include office lighting fixtures, air conditioning equipment, and ventilation equipment installation work, interior work, power line wiring work, information wiring work in buildings, wireless equipment work, and building management system installation work. There is

(3.1) 3D Model Acquisition Step In the 3D model acquisition step S11, similar to the 3D model acquisition step S1 of the integrated data generation method shown in FIG. is acquired from the measurement unit 1.

In the three-dimensional model acquisition step S11, the integrated data generation unit 22 may acquire three-dimensional model data converted from the two-dimensional drawing data of the building. In the case of the A construction, the integrated data generation unit 22 may acquire the three-dimensional model of the building created by the main contractor.

(3.2) Integrated Data Step Next, integrated data step S12 performs the same processing as linking step S2, integrated data creation step S3, and storage step S4 of the integrated data generation method shown in FIG. That is, by the processes in the three-dimensional model acquisition step S11 and the integrated data step S12, integrated data including the three-dimensional model and the work object OA linked to the target area 9 of the three-dimensional model is stored in the storage unit 26. be.

At this point, the on-site agent can make an outline process design while confirming the conditions of the construction site and requests from the site supervisor such as the client and the main contractor. The on-site agent identifies the work target for each day with a three-dimensional model as a schematic process design. The work target is identified by linking the work object OA to the target area 9 of the three-dimensional model. For example, the linking unit 21 attaches the first work object OA1 to the element model M26 of the three-dimensional model in accordance with the terminal operation of the on-site agent, thereby attaching the first work object OA1 to the element target area 91 of the element model M26. Link OA1. In addition, the linking unit 21 sets the spatial target area 92 in the three-dimensional model according to the terminal operation of the on-site agent, and links the second work object OA2 to the spatial target area 92 .

Then, the on-site agent attaches the work objects OA (first work object OA1, second work object OA2) pasted to the target area 9 (element target area 91, spatial target area 92) of the three-dimensional model to the information terminal B1. By arranging it on the Gantt chart displayed on the display G1 of , an outline process flow for each day can be easily created. In addition, even when the equipment or components used in the building are changed or the arrangement position of the equipment is changed by agreement with the client, other contractors, or logistics companies, only the changed points are extracted from the integrated data. By doing so, it is possible to automatically correct the schematic process flow. Also, by replacing the work object OA, the general process flow can be changed. In addition, by using a learning model built by machine learning using the Gantt chart created and modified procedures in the outline process flow of past construction as training data, the outline process design can be automatically created, reducing the work load of the on-site agent. can be reduced.

(3.3) Work Object Confirmation Step and Notification Step Next, in the work object confirmation step S13, the construction plan creation unit 31 determines whether or not the integrated data in the storage unit 26 has omissions in the setting of the work object OA.

Specifically, when the on-site agent prepares the general process flow, he/she designates the target range for the three-dimensional model of the integrated data displayed on the display G1 of the information terminal B1. The construction plan creation unit 31 extracts all work objects OA included in the specified range, and determines whether or not information is set for each attribute of the extracted work objects OA. In the work object confirmation step S13, the construction plan creation unit 31 sets the work object OA for which information is not set for at least one attribute as an unset work object.

If there is an unset work object, the construction plan creation unit 31 transmits information on the unset work object to the information terminal B1. The information terminal B1 displays the information of the unset work object on the display G1, thereby notifying the on-site agent that there is an omission in setting the work object OA (notification step S20). That is, in the construction plan management system A1, if there is an omission in the setting of the work object OA, the information terminal B1 displays the part of the omission in the setting, and prompts the on-site agent to set the work object OA (for example, manual setting).

The construction plan creation unit 31 repeats the integrated data step S12, the work object confirmation step S13, and the notification step S20 until there is no omission in the setting of the work object OA.

FIG. 12 shows first work objects OA11, OA12, and OA13 as examples of three first work objects OA1 with no missing settings. The first work object OA11 is the first work object OA1 linked (pasted to the element model M261) with the target area 911 (see FIG. 6). The first work object OA12 is the first work object OA1 linked (pasted to the element model M262) with the target area 912 (see FIG. 6). The first work object OA13 is the first work object OA1 linked (pasted to the element model M263) with the target area 913 (see FIG. 6).

(3.4) Flow Creation Step Next, in flow creation step S14, the construction plan creation unit 31 creates a Determine the order in which the corresponding tasks should be performed. Then, the construction plan creation unit 31 develops the work for each work type of the work object OA in parallel. Then, the construction plan creation unit 31 creates an optimum work flow indicating the flow of work included in each of the plurality of work objects OA. Furthermore, it is preferable that the construction plan creation unit 31 creates a process flow based on the optimum work flow. Note that this flow creation process may be performed on a Gantt chart.

Flow creation processing will be described below using the first work objects OA11, OA12, and OA13 in FIG.

The construction plan creation unit 31 creates the first work objects OA11, OA12, OA13 based on the position information (the position of the target area 91) set in the attribute "work position" of each of the first work objects OA11, OA12, OA13. Determine the work order of the OA 13. For example, the construction plan creation unit 31, based on the attribute "work position" of each of the first work objects OA11, OA12, and OA13, based on the worker's flow line, the arrival status of elements, the worker's status, etc. Decide on a work order that allows work to proceed efficiently. Here, as shown in FIG. 13A, the construction plan creation unit 31 creates a construction flow F1 that proceeds in order of the first work objects OA11, OA12, and OA13.

Next, as shown in FIG. 13B, the construction plan creation unit 31 develops the first work object OA1 into each work type included in the first work object OA1 to create a work flow F2. The first work object OA11 is developed into work types W11 to W14 corresponding to the four work types included in the first work object OA11. The first work object OA12 is developed into work types W21 to W24 corresponding to the four work types included in the first work object OA12. The first work object OA13 is developed into work types W31 to W34 corresponding to the four work types included in the first work object OA13. The work types W11, W21, and W31 are "transportation". The work types W12, W22, and W32 are "wiring". The work types W13, W23, and W33 are "assembly". The work types W14, W24, and W34 are "inspection".

Next, as shown in FIG. 14A, the construction plan creation unit 31 develops work types W11 to W14, work types W21 to W24, and work types W31 to W34 of the work flow F2 in parallel to obtain the optimum work. Create flow F3. In FIG. 14A, the construction plan creation unit 31 creates an optimum work flow F3 in which up to three types of work proceed simultaneously, assuming division of labor by up to three workers. That is, the optimal work flow F3 optimizes the flow of each work type of the work flow F2 so that each work of the first work objects OA11, OA12, and OA13 can be completed in the shortest possible number of workers who can divide the work. Flow.

Next, as shown in FIG. 14B, the construction plan creation unit 31 creates a process flow F4 by optimizing the work schedules of the first work objects OA11, OA12, and OA13 based on the optimum work flow F3. Here, "optimization of the work schedule" means creating a process flow F4 that can complete each work of the first work objects OA11, OA12, and OA13 in the shortest possible number of workers who can divide the work.

For example, the construction plan creation unit 31 can automatically create the optimum work flow F3 using the work time for each work type. In addition, when the optimum work flow F3 is changed due to an arrangement with the client, a distributor, or a trader in another industry, the construction plan creation unit 31 can read only the changed points and change the process flow F4. In addition, when the construction planning unit 31 determines that the total working hours of the process flow F4 exceeds the prescribed working hours per day, the construction planning unit 31 extends the working hours of the worker, or By moving some of the work objects OA, the construction flow F1, the work flow F2, the optimum work flow F3, and the process flow F4 on the day can be corrected.

Furthermore, the site agent can modify the optimum work flow F3 by moving the work type while assuming the workers who can be utilized from the situation of the construction site and the planned construction cost.

(3.5) Flow Confirmation Step and Notification Step Next, in flow confirmation step S15, the on-site agent confirms the optimum work flow F3 or process flow F4 displayed on the display G1 of the information terminal B1. Specify a range of flows. The construction plan creation unit 31 extracts all work types included in the specified flow range and determines whether or not there is an omission in the setting of work types in the flow.

If there is a work type setting omission, the construction plan creation unit 31 transmits information on the work type setting omission to the information terminal B1. The information terminal B1 notifies the on-site agent that there is an omission in the setting of the work type by displaying information on the omission in the setting of the work type on the display G1 (notification step S21). That is, in the construction plan management system A1, if there is an omission in the setting of the work type, the information terminal B1 displays the location of the omission in the setting, and prompts the on-site agent to set the work type (for example, manual setting).

The construction plan creation unit 31 repeats the flow confirmation step S15 and the notification step S21 until there is no work type setting omission in the flow.

When there is no work type setting omission in the flow, the construction plan creation unit 31 includes each data of the created optimum work flow F3 and process flow F4 in the integrated data and stores it in the storage unit 26 . That is, the integrated data includes each data of the three-dimensional model of the building, the work object OA, the element object OB, the optimum work flow F3, and the process flow F4. Therefore, the construction plan management system A1 can centrally manage each piece of information on the construction site using integrated data.

The data output unit 4 outputs each data of the optimum work flow F3 and the process flow F4 to the output device 5 . The output device 5 receives the data of the optimum work flow F3 and the process flow F4, and displays the data of the optimum work flow F3 and the process flow F4 on the display device.

(3.6) Construction plan creation step Next, in construction plan creation step S16, the construction plan creation unit 31 performs daily construction using the work type and the work time based on the optimum work flow F3 and the process flow F4. create a plan; The construction plan creation unit 31 may use at least one of the optimum work flow F3 and the process flow F4 as the construction plan.

The site agent can estimate the number of available workers based on the availability of workers, the situation of the construction site, the planned construction costs, etc., and modify the construction plan.

The construction plan creation unit 31 changes the optimum work flow F3 and the process flow F4 if there is a need to change the optimum work flow F3 and the process flow F4 in conjunction with the modification of the construction plan by the site agent.

(3.7) Plan Confirmation Step and Notification Step Next, in plan confirmation step S17, construction plan creation unit 31 determines the validity of the construction plan created in construction plan creation step S16.

For example, the construction plan creation unit 31 determines whether or not there is an error in the construction plan created in the construction plan creation step S16. If there is an error in the construction plan, the construction plan creation unit 31 transmits information about the error to the information terminal B1. The information terminal B1 notifies the on-site agent that there is an error in the construction plan by displaying the error information on the display G1 (notification step S22). That is, in the construction plan management system A1, if there is an error in the construction plan, the information terminal B1 displays the location of the error and prompts the on-site agent to correct the error (for example, manual correction).

Further, if there is a bottleneck work with low work efficiency in the work plan, the construction plan creation unit 31 adds information on the bottleneck work and transmits the information on the bottleneck work to the information terminal B1. The information terminal B1 displays information on the bottleneck work on the display G1, thereby notifying the on-site agent of the presence of the bottleneck work (notification step S22). That is, the construction plan management system A1 prompts the site agent to modify the construction plan according to the bottleneck work.

The construction plan creation unit 31 repeats the plan confirmation step S17 and the notification step S22 until there are no errors in the construction plan and no bottleneck work.

When the error in the construction plan and the bottleneck work are eliminated, the construction plan creation unit 31 includes data of the created construction plan in the integrated data and causes the storage unit 26 to store the integrated data. That is, the integrated data includes each data of the three-dimensional model of the building, the work object OA, the element object OB, the optimum work flow F3, the process flow F4, and the construction plan. Therefore, the construction plan management system A1 can centrally manage each piece of information on the construction site using integrated data.

The data output unit 4 outputs construction plan data to the output device 5 . The output device 5 receives the construction plan data and displays the construction plan data on the display device (data output step).

(3.8) Quotation Creation Step Next, in the estimate creation step S18, the construction plan creation unit 31 creates a construction estimate based on the construction plan created in the plan confirmation step S17.

Specifically, the construction plan creation unit 31 obtains the labor cost for the work by accumulating the work time and the worker unit price of each work.

Also, the construction plan creation unit 31 obtains the material cost by adding up the prices of the elements corresponding to the element objects OB in the three-dimensional model.

In addition, the construction plan creation unit 31 obtains the costs required for tools such as heavy machinery and tools used in the work, and other necessary costs.

Then, the construction plan creating unit 31 creates an estimate for construction using each piece of information such as labor costs, material costs, tool costs, and other necessary costs.

The construction plan creating unit 31 stores the data of the created quotation in the integrated data in the storage unit 26 . That is, the integrated data includes each data of the three-dimensional model of the building, the work object OA, the element object OB, the optimum work flow F3, the process flow F4, the construction plan, and the quotation. Therefore, the construction plan management system A1 can centrally manage each piece of information on the construction site using integrated data.

The data output unit 4 outputs the data of the written estimate to the output device 5 . The output device 5 receives the data of the written estimate and displays the data of the written estimate on the display device.

(3.9) Actual Work Feedback Step At the construction site, each work is carried out according to the construction plan created by the processes of S1-S18 and S20-S22 described above.

If the construction plan is changed due to agreements with each contractor, delays in delivery of materials and equipment due to logistics problems, and troubles related to workers, the on-site agent will notify the work start time and workers regardless of the current work plan. can change their working hours.

For example, if the on-site agent determines that the time required for a certain task significantly exceeds the prescribed working hours per day, the worker's working hours may be extended, or the next day's construction flow (or Gantt chart) may be partially revised. Move the work object OA.

In addition, the work plan data can be accessed by the work manager and workers other than the on-site agent, and the work manager and workers can easily reflect the progress of the work in the work plan. Alternatively, the construction plan management system A1 can automatically collect the progress of work by IoT devices such as cameras installed at the construction site.

The changes in the construction plan by the on-site agent, the input of work progress by the work manager and workers, and the work progress collected by the IoT device reflect the work results in the building, and the work It corresponds to performance data according to the performance of

Therefore, in the actual work feedback step S19, the feedback unit 32 acquires the performance data, and updates the element-by-element information of the element object OB in the integrated data based on the performance data. The element-specific information to be updated is, for example, information of the attribute "work time", but may be information of the later-described attribute "work level".

For example, based on the performance data, the feedback unit 32 measures or detects the number of workers, working time, and worker level for each work type, and stores them in the storage unit 26 . Then, the feedback unit 32 provides design information (installation position, surrounding conditions, etc.), construction environment information (weather, delay in previous process, schedule review, etc.), work learning effect (the higher the building, the more actual A learning model built using machine learning is used to analyze information on influencing factors such as shorter work hours, etc., and worker characteristics (work efficiency drops on weekends, etc.) to identify variations in work hours. Predict.

In this way, the feedback unit 32 can grasp the problems at the construction site by feeding back the performance data, and update the integrated data, especially the element-by-element information of the element objects, to the information suitable for the actual work. can.

(4) First Modification FIG. 15A shows a modification of the element object OB. Element object OB may further have "work level" in addition to "element object name", "work position", "work type" and "work time" as attributes. Element-specific level information indicating the difficulty level of the work set in the "work type" is set in the attribute "work level" of the element object OB. In FIG. 15A, the difficulty level is represented by any number 1, 2, or 3, and the higher the number, the higher the difficulty level.

FIG. 15B shows a modification of the work object OA. The work object OA further has "work level" in addition to "work type", "work position", and "work time" as attributes. If the work object OA is the first work object OA1, the linking unit 21 sets the element-by-element level information included in the element object OB to the attribute "work level" of the first work object OA1.

If the work object OA is the second work object OA2, the linking unit 21 sets the element-specific level information corresponding to the terminal operation to the attribute "work level" of the first work object OA1.

In this modified example, by adding a "work level" to each attribute of the element object OB and the work object OA, it is possible to create a construction plan that considers the degree of difficulty of the work.

(5) Second Modification The linking unit 21 preferably links external information, which is information about the exterior of the building, to the three-dimensional model.

External information is information on the exterior of the building. The exterior of the building includes the site around the building, houses, shops, schools, roads, and the like near the building.

External information about the site surrounding the building includes construction passage information such as the dimensions between the outer wall of the building and the outer edge of the site, neighboring house information such as agreements with neighbors regarding construction, and store information such as stores in the neighborhood. and so on. Note that the specific content of the external information is not limited to the content described above, and may be information on the exterior of the building.

For example, FIG. 16 shows a floor plan of a three-dimensional model M2 displayed on the display G1 of the information terminal B1. Then, the linking unit 21 links the external information input by the terminal operation to the external information area 8 designated by the terminal operation. One external information area 8 may be associated with at least one piece of external information, and one external information area 8 may be associated with a plurality of pieces of external information.

In FIG. 16 , external information areas 81 and 82 are set as the external information area 8 . The external information area 81 is formed outside the site model M27, and in the external information area 81, there is an agreement with the neighbor's house stating "Agreement with XX's house: Construction hours are possible from 9:00 a.m. to 5:00 p.m." External information (neighboring house information) is linked. The external information area 82 is formed in the space between the structure model M20 and the outer edge of the site model M27. Passage information) is linked.

It should be noted that if the external information area 8 is set to a nearby store model, the external information includes store information such as the type of store, business hours, and the time required to reach the store.

As described above, the integrated data generation system 2 associates the external information with the external information area 8, so that the information around the building can be reflected in the three-dimensional model M2. As a result, external information is included in the integrated data.

(6) Third Modification Each function of the construction plan management system A1 may be distributed to a plurality of devices, and the plurality of devices may constitute the construction plan management system A1. For example, the construction plan management system A1 may be realized by cloud computing technology.

Moreover, the construction plan management system A1 may be composed of one device such as a personal computer.

Also, the construction plan management system A1 may include at least the construction plan creation unit 31 and the data output unit 4 .

Further, the data output unit 4 outputs the construction plan data to the output device 5 in the data output step. If the integrated data in the storage unit 26 includes the construction plan, the data output unit 4 can output the construction plan data at any timing.
