Description

[Technical Field]

[0001] The present invention relates to a construction management device, a construction management method, and a construction management program for managing construction of a building using a three-dimensional model analysis program. [Background technology]

[0002] In recent years, in the field of civil engineering and public works such as bridges, tunnels, dams, earthworks, and rivers, the Ministry of Land, Infrastructure, Transport and Tourism has established guidelines and is attempting to systematically promote the smooth introduction of CIM (Construction Information Modeling / Management), with the aim of speeding up consensus building, streamlining work, improving quality, and ultimately improving productivity through work transformations such as a shift from 2D drawings to 3D models when constructing various structures, or front-loading, which allows for intensive advance consideration by placing a burden on the early stages of the process (front), preventing potential rework in later stages and improving quality and shortening construction time.To this end, a variety of 3D model analysis programs and software for creating 3D CIM models have been developed.

[0003] Furthermore, unlike traditional 3D CAD, which primarily targets architectural structures and involves creating 2D drawings, assembling the 3D shape, and then simulating it using CG, BIM models created using BIM (Building Information Modeling) are being developed, which allow for 3D designs to be created from the beginning. Because BIM models are a collection of 3D objects, it is possible to add attribute data such as cost, finish, and management information to these objects, making it possible to utilize the information accumulated in the model throughout the entire life cycle of a building, from design and construction to maintenance. Various 3D CAD software programs, such as "ArchiCAD" and "Revit," are known as BIM tools that can create BIM models.

[0004] Furthermore, various process management software programs are known for managing the planning and implementation of public works projects, for example, so that construction work is completed within the designated construction period. Construction management systems have also been developed that combine 3D CAD software capable of creating BIM and CIM models with process management software to easily create 4D models that incorporate time-based elements into the 3D graphic display of a building, for example, at a construction site, thereby enabling 4D simulation (see, for example, Patent Document 1). The Ministry of Land, Infrastructure, Transport and Tourism is attempting to apply the 4D simulation function of such 4D models over time to 3D BIM and CIM models, thereby expanding the scope of civil engineering public works projects (see, for example, Non-Patent Document 1).

Summary of the Invention [Problem to be solved by the invention]

[0007] Meanwhile, in the field of building construction, improving productivity has become an urgent issue, and efforts are being made to improve efficiency by utilizing ICT, particularly BIM / CIM (Building / Construction Information Modeling and Management) and measurement sensors such as IoT sensors, which will enable centralized management of construction information and 3D visualization.

[0008] Here, IoT sensors are preferably used as measurement sensors, as they are sensors that can be connected to a network to collect and manage information, and make it possible to monitor various on-site conditions in real time and utilize the collected information for predictive maintenance, early warning monitoring, data accumulation, quality improvement, etc. At construction sites of buildings such as public civil engineering works, the use of measurement sensors such as IoT sensors will enable labor savings in various measurement tasks, and the automatic collection of measurement data (sensing data) by the sensors is expected to significantly reduce the labor spent on managing and monitoring the construction site and its surrounding on-site conditions. However, at construction sites, there is concern that new labor will be required to manage measurement data from measurement sensors such as IoT sensors.

[0009] That is, at a construction site, as construction progresses, the site conditions change over time due to daily construction work. Sometimes, the installation location of measurement sensors, such as IoT sensors, is moved or changed due to replacement, which can easily cause fluctuations in measurement data due to factors unrelated to the measurement items. For this reason, when engineers try to properly understand the site conditions from fluctuations in the measurement data values ​​and determine countermeasures, it is difficult to interpret the relationship between the measurement data and the site conditions that change over time, which changes over time, and to determine appropriate countermeasures using only the measurement data from measurement sensors, such as IoT sensors. Furthermore, for example, in the case of a measurement item that is set to issue a warning to engineers when the measurement data exceeds a control value, it becomes necessary to manage the measurement data from measurement sensors, such as IoT sensors, on a daily basis and reset the control value for that measurement item as construction progresses. This requires a great deal of effort, such as data organization.

[0010] In response to this, for example, studies are being conducted to centrally manage measurement data from various sensors on a 3D model using BIM / CIM, thereby visualizing sensor information at specific locations and components of a building, allowing engineers to easily visually grasp the relationship between sensor information and on-site conditions (see, for example, Non-Patent Document 2). According to Non-Patent Document 2, with regard to the association between 3D models and sensor information, a bridge data model and a sensor data model, as well as an association data model that links these, are being developed, and by using the developed association data model, it has become possible to associate and manage sensor data on a 3D model with the data model of the bridge, which is a construction.

[0011] However, according to the method of managing sensor data by associating it with a data model of a building described in Non-Patent Document 2, the linked data model is intended for sensors installed in already completed buildings and is intended to be used primarily for monitoring for maintenance and management. Therefore, it is not intended for a building construction site where the on-site situation changes frequently over time during monitoring, and it is therefore difficult to reflect the on-site situation that changes daily and to appropriately grasp measurement data from measurement sensors such as IoT sensors together with management values ​​in a 4D model of the building construction site so as to be able to manage the on-site situation.

[0012] The present invention aims to provide a construction management device, a construction management method, and a construction management program that reflect the on-site conditions that change daily and enable easy and appropriate understanding of measurement data from measurement sensors such as IoT sensors together with management values ​​in a four-dimensional model of the construction site, thereby managing the on-site conditions.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The construction management device 10 according to a preferred embodiment of the present invention shown in Figure 1 is used, for example, in a railway underground construction project (see Figure 2) in which a railway box 41 is constructed underground as a building adjacent to an in-service track 40. In order to quickly confirm the impact of the construction on the in-service track 40 due to the construction, various measuring devices 42 (see Figures 3 and 4), preferably using measurement sensors such as IoT sensors, are installed at various locations on the construction site, and the device is used as a management device, preferably a computer, to properly grasp and manage the on-site situation at the construction site by measuring, for example, the displacement of temporary retaining walls, the displacement of the track construction base, the displacement of existing electric line equipment, the displacement of surrounding structures and the ground, etc., along with the date and time of measurement. The construction management device 10 of this embodiment references sensing data (measurement data) output in, for example, CSV format from a measurement management system 20 (see FIG. 1 ), which collectively manages data measured by measuring devices 42, preferably using IoT sensors, installed at specified locations or specified components at the construction site. Alternatively, the device imports the data as converted data into the sensing data storage unit 14. The device visualizes the sensing data along with control values ​​in a 4D model, preferably a BIM / CIM 3D model associated with process data from a process management program, allowing for real-time display and reproduction of the site conditions. The construction management device 10 of this embodiment has a function for easily and appropriately managing measurement data (sensing data) preferably from IoT sensors against control values ​​in a 4D model of the construction site of a building under construction, which reflects the daily changing site conditions with process data.

[0029] The construction management device 10 of this embodiment is a management device that manages the construction of a building using a 3D model analysis program built into a computer, and as shown in Figure 1, is configured to include a measurement management unit 11 that can manage the construction of a building based on 3D design data of a 3D design model 30 of the building, which is created using a 3D CAD program and preferably includes a model 30b of a temporary structure (see Figure 4), process data for constructing the building, which is created using a process management program, and sensing data regarding the surrounding ground, temporary structures, or existing structures when constructing the building, which is measured by a measurement sensor, preferably an IoT sensor.

[0030] The 3D design data of the 3D design model 30 of the building is linked to measuring equipment 42 using measurement sensors from each IoT sensor, and a sensor model 31 that can reflect the information of the sensing data measured by each measurement sensor is created by placing it at a predetermined location on the 3D design model 30 of the building that requires measurement by the measurement sensor.

[0031] The measurement management unit 11 includes a construction linking unit 15 that associates the 3D design data of a predetermined construction portion of the 3D design model 30 of the building in which the sensor model 31 is arranged with a predetermined process item 33 in the process data (see FIGS. 8 and 9) that requires measurement by a measurement sensor, for example, and a site status display unit 16 that displays on a screen the site status data of the predetermined construction portion of the 3D design model 30 of the building in which the sensor model 31 is arranged as the time axis progresses. The measurement management unit 11 also includes a control value storage unit 26 and an automatic control value conversion unit 27, and the control value storage unit 26 stores, for each predetermined process item 33 that requires measurement by a measurement sensor, a control value set for sensing data measured by one or more measurement sensors in the process item 33. The control value automatic conversion unit 27 automatically retrieves the control value to be used for the next process item 33 stored in the control value storage unit 26 at a predetermined timing when one process item 33 switches to the next process item 33, and compares the retrieved control value in the next process item 33 with sensing data from the measurement sensors as the time axis progresses during construction of the next process item 33, referenced based on data related to the actual start date and time of the next process item 33. The site status display unit visualizes the comparison results between the compared sensing data and the control value, together with the sensor model 31 that can reflect sensing data information, on the screen of a predetermined construction site of the 3D design model 30 of the building on which the displayed sensor model 31 is arranged, thereby enabling management of the construction of the building.

[0032] Furthermore, in this embodiment, the measurement management unit 11 preferably includes a measurement data reference unit 19 and a measurement value control value comparison unit 24, and the measurement data reference unit 19 is configured to reference sensing data obtained as the time axis progresses during the construction of a predetermined process item 33, based on data relating to the actual start date and time of the predetermined process item 33 in the process data. The measurement value control value comparison unit 24 is configured to compare sensing data obtained by a measurement sensor as the time axis progresses during the construction of the predetermined process item 33, referenced by the measurement data reference unit 19 based on data relating to the actual start date and time of the predetermined process item 33 in the process data, with a control value.

[0033] Furthermore, in this embodiment, the sensing data, preferably obtained by an IoT sensor, referred to by the measurement data referring unit 19 is, for example, data in a measurement management system 20, which will be described later.

[0034] Furthermore, the construction management device 10 of this embodiment preferably includes a 3D design data storage unit 12 that stores 3D design data, a process data storage unit 13 that stores process data, and a sensing data storage unit 14 that stores sensing data measured by each measurement sensor. The construction management device 10 may further include a data acquisition unit 17 that acquires all or any of the 3D design data, process data, and sensing data.

[0035] In this embodiment, the construction management device 10 is configured to include a general-purpose computer such as a personal computer as an information processing device. The computer is equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), I / F (Interface), HDD (Hard Disk Drive), storage means, input means, display means, output means, etc. The CPU controls the overall operation of the construction management device 10 in accordance with various control programs stored in the ROM, using the RAM as a work area. In addition, by incorporating various computer programs into the ROM, the CPU is able to operate the storage means, input means, display means, output means, etc., and is also able to store various data such as 3D design data of the 3D design model 30 of the construction, which includes, as 3D objects, a model 30a of the main structure of the construction (see Figure 3), a model 30b of the temporary structure (see Figure 4), a model 30c of the existing structure (see Figure 3), and a model 30d of the surrounding ground (see Figure 3), as well as process data and sensing data, in the database section that forms the storage units 12, 13, and 14, and to display specified information on the screen of a display or the like by the display means, or to output it from a printer or the like by the output means.

[0036] In this embodiment, a known 3D model analysis program is incorporated into the computer-based construction management device 10, and the 3D model analysis program has functions for creating 3D models, displaying point clouds, acquiring information, and analyzing the data. The 3D model analysis program can provide a development environment for the software side to implement a measurement management unit 11, which includes various storage units 12, 13, and 14, a data acquisition unit 17, a construction linking unit 15, a measurement data reference unit 19, a site status display unit 16, a control value setting unit 23, a measurement value control value comparison unit 24, a warning information issuing unit 25, a control value storage unit 26, and an automatic control value conversion unit 27, as described below. An example of a 3D model analysis program (3D model analysis software) that can provide such a development environment for the software side is the software "PADMS" manufactured by Pasco Corporation.

[0037] In this embodiment, as described above, the construction management device 10 preferably includes a three-dimensional design data storage unit 12. The three-dimensional design data storage unit 12 stores design data for a three-dimensional design model 30 of a construction site situation, including a model 30a of a main structure (see FIG. 3), a model 30b of a temporary structure (see FIG. 4), a model 30c of an existing structure (see FIG. 3), and a model 30d of the surrounding ground (see FIG. 3), created using a three-dimensional CAD program when constructing a railway box 41, which is a construction to be installed adjacent to an in-service track 40, as a main structure. The design data for the three-dimensional design model 30 of the construction site situation, including the model 30b of the temporary structure, can be created by a three-dimensional design model creation unit 21a using a known three-dimensional CAD program incorporated in a three-dimensional design device 21 separate from the construction management device 10, and can be imported into the construction management device 10 via, for example, a storage medium or a wired or wireless communication network, and stored in the three-dimensional design data storage unit 12. The design data of the 3D design model 30 of the construction site situation, including the model 30b of the temporary structure, may be created by a 3D design model creation unit 21a using a known 3D CAD program incorporated into the construction management device 10, and may be stored in the 3D design data storage unit 12.

[0038] Preferably, the 3D CAD program (3D CAD software) for incorporating the 3D design model creation unit 21a into the 3D design device 21 is "Revit" by Autodesk, a BIM tool capable of creating BIM models. The 3D design model 30 of the construction site, including the temporary structure model 30b created by the 3D design model creation unit 21a, includes, as 3D objects, sensor models 31 (see FIGS. 3 and 4), which are preferably icons resembling the shapes of measuring devices 42 using each measurement sensor and can reflect information on sensing data measured by the measurement sensors, as described below. These sensor models 31 are placed at predetermined locations requiring measurement by the measurement sensors.

[0039] In this embodiment, the construction management device 10 is also equipped with a process data storage unit 13, which stores process data created using a process management program for constructing a railway box 41, a construction to be installed adjacent to an in-service track 40, as a main structure. The process data for constructing the railway box 41, a construction, can be created by a process data creation unit 22a using a known process management program incorporated in a process management device 22 separate from the construction management device 10, and can be imported into the construction management device 10 via a storage medium or a wired or wireless communication network, for example, and stored in the process data storage unit 13. The process data for constructing the railway box 41, a construction, can also be created by a process data creation unit 22a using a known process management program incorporated in the construction management device 10, and can be stored in the process data storage unit 13.

[0040] Preferably, a process management program (process management software) for incorporating the process data creation unit 22a into the process management device 22 can be, for example, "Being Project-CCPM" manufactured by Being Corporation, which is a program equipped with a CCPM (Critical Chain Project Management) function. The process data created by the process data creation unit 22a includes, for example, for a plurality of process items 33 (see FIG. 8) when constructing each of the divided construction areas, information on the order of each process item 33 and the process period consisting of the planned start date and planned end date of each process. The process items 33 are made up of items such as rebar assembly, scaffolding assembly, shoring assembly, formwork assembly, and removal of temporary materials (scaffolding, shoring, formwork) for each specified construction area.

[0041] Here, the process management program with CCPM functionality is preferably a process management software (process management program) that employs critical chain project management (CCPM), developed with a view to overall optimization based on the theory of constraints (TOC). Critical chain is a method that considers dependencies in the work process when determining the execution order of each task in a project, in addition to the traditional critical path method that considers dependencies in the work process. Project management is a practical method for managing projects with the objectives of shortening construction time and meeting deadlines, taking into account the human psychology and behavioral characteristics of personnel, as well as social and organizational issues. The safety margins removed from each task are aggregated and managed in a "buffer." The process management program with CCPM functionality preferably also has functions for reflecting cost estimation information, setting daily construction volume and non-work days, and setting critical paths (CPs). Preferably, a process management program without CCPM functionality can be used as the process management program for incorporating the process data creation unit 22a into the process management device 22.

[0042] Furthermore, in this embodiment, the construction management device 10 is equipped with a sensing data storage unit 14, and the sensing data storage unit 14 preferably retrieves and stores measurement data measured by measurement sensors from the measurement management system 20, along with the measurement date and time, regarding the surrounding ground, temporary structures, existing structures, etc., when constructing a railway box 41, which is a construction to be installed adjacent to an in-service track 40, as the main structure, as sensing data included in the measurement information managed by the measurement management system 20. The sensing data (measurement data) when constructing a railway box 41, which is a construction, as the main structure, is accumulated in the measurement management system 20, which is provided separately from the construction management device 10 and includes a measurement management device connected to each measurement sensor by wire or wirelessly, and can be retrieved into the construction management device 10 via, for example, a storage medium or a wired or wireless communication network, and stored in the sensing data storage unit 14. The sensing data (measurement data) obtained when constructing a railway box 41, which is a construction item, as the main structure may be stored in the sensing data memory unit 14, for example, by a known measurement management program incorporated in the construction management device 10, and accumulated in the measurement management unit 11 connected to each measurement sensor.

[0043] When constructing a railway box 41 as a main structure, a measurement management system 20 for acquiring and managing sensing data (measurement data) measured by measurement sensors, preferably IoT sensors, can be preferably a management system manufactured by Keisoku Techno Co., Ltd. Data related to displacement, change, or load of the surrounding ground, temporary structures, existing structures, etc., measured by measurement sensors, preferably IoT sensors, during construction of the building, includes, for example, construction base settlement, overhead line pole settlement, strut axial force, retaining wall horizontal displacement, rebound, on-site groundwater level, off-site groundwater level, intermediate section displacement, retaining wall internal displacement, strut temperature, etc. Measurement devices 42, preferably using IoT sensors as measurement sensors for measuring this sensing data, can include, for example, a water-filled settlement gauge, a small inclinometer, a strain gauge, a multi-stage inclinometer, a rock inclinometer, a pore water pressure gauge, a water level gauge, a laser distance sensor, a thermometer, etc.

[0044] In this embodiment, the design data for the 3D design model 30 of the building, preferably stored in the 3D design data storage unit 12 and created by the 3D design model creation unit 21a of the 3D design device 21, includes, as 3D objects, data on the main structure model 30a, the temporary structure model 30b, the existing structure model 30c, the surrounding ground model 30d, and the like, which are models of the railway box 41 of the building, as described above. The design data for each of these structure models 30a, 30b, 30c and the surrounding ground model 30d is provided with management information such as the ID number, file path, and node path of each model (object). The design data for each of the sensor models 31 created as 3D objects by the 3D design model creation unit 21a is also provided with management information such as the ID number, file path, and node path of the measuring instrument 42 (see FIG. 1).

[0045] In this embodiment, the process data for each of the multiple process items 33, such as rebar assembly, scaffolding assembly, shoring assembly, formwork assembly, and removal of temporary materials (scaffolding, shoring, and formwork) at each of the divided construction sites, preferably during the construction of the railway box 41 as a main structure, which is preferably stored in the process data storage unit 13 and created, for example, by the process data creation unit 22a of the process management device 22, is assigned management information such as an ID number, process name, planned start date, and planned end date for each work type (see FIG. 1). When actually carrying out construction, information regarding the actual start date and time and actual end date and time, which are the actual start date and time of the actual construction, can be input into the construction management device 10 by, for example, a worker as data regarding the actual start date and time of a specific process item 33 in the process data. By assigning data relating to the start date and time of actual construction work, particularly data relating to the start date and time of actual construction work (start date and time of actual construction work), to the data of each specified process item 33, it becomes possible to refer to the sensing data included together with the measurement date and time in the measurement value information of each measuring device 42, which is managed in the measurement management system 20 or sent from the measurement management system 20 and stored in the sensing data storage unit 14, by the measurement data reference unit 19 of the measurement management unit 11 (described later), based on the assigned data relating to the start date and time of actual construction work. This makes it possible to include sensing data, preferably from an IoT sensor, included in the measurement value information in the measurement value information in the data of the site situation as the construction of the specified process item 33 progresses on the time axis, and to visualize it on a screen as time-series data that can be displayed on the time axis of the building under construction.

[0046] Furthermore, in this embodiment, the measurement information, including sensing data from each measuring device 42, which is managed by the measurement management system 20 or sent from the measurement management system 20 and stored in the sensing data storage unit 14, includes two types of data: measurement data and management value data. The measurement data consists of measurement device information and measurement value information. The measurement device information includes information such as the ID number of the measuring device 42, the name of the measurement item, the installation position (e.g., distance, depth), units, the file path of the model layer, and the node path. The measurement value information includes information such as the ID number of the measuring device 42, the measurement date and time, and the measurement value (sensing data). The measurement value information is information acquired by each measurement sensor at specific time intervals, for example, from several minutes to one day. Since the measurement frequency varies depending on the measuring device 42, a representative value must be determined when linking with the sensor model 31. When representing the measurement value information in the construction management device 10, it is desirable to match the latest construction progress status. Therefore, it is preferable to use the most recent measurement value from the measurement sensor as the representative value of the measurement value information.

[0047] Moreover, the measurement values ​​(sensing data) are preferably output in CSV format from the measurement management system 20. The measurement values ​​(sensing data) are preferably referenced by the measurement data reference unit 19 or stored in the sensing data storage unit 14 of the measurement management system 20 together with attribute information based on the measurement instrument information.

[0048] On the other hand, the control value data indicates a threshold value of the measurement value (sensing data) obtained by the measurement sensor, and can be used for management purposes such as issuing a warning when the measurement value exceeds the control value.

[0049] The control value data includes the same measuring instrument information as the measurement data, as well as control value information, and as described above, the measuring instrument information includes information such as the ID number of the measuring instrument 42, the name of the measurement item, the installation position based on distance, depth, etc., the unit, the file path of the model layer, the node path, etc. The control value information includes information such as the ID number of the measuring instrument 42, the application date, and the control value. Since the control values ​​are subject to change or addition as the construction progresses, the control value setting unit 23 (described later) can set or change the value of the control value to be applied as appropriate according to the reference date and time.

[0050] According to this embodiment, measurement value information such as sensing data contained in measurement data from each measuring device 42, preferably using an IoT sensor as a measurement sensor, and control value information such as control values ​​contained in control value data can be linked to the sensor model 31 in the 3D design model 30 of the building of the site situation created by placing sensor models 31 assigned the ID numbers of similar measuring devices 42 at predetermined locations, via the ID numbers of the measuring devices 42 in the measurement device information. This also makes it possible to associate measurement value information including sensing data, etc., and control value information including an application time point (a reference date and time) and control values, etc., which are managed in the measurement management system 20 or imported from the measurement management system 20 and preferably stored in the sensing data storage unit 14, with the sensor model 31 in the 3D design data of the 3D design model 30 of the building of the site situation, which has a railway box 41 as the main structure, with the sensor model 31, and to reflect them on the screen together with the displayed sensor model 31.

[0051] Therefore, in this embodiment, the 3D design data of the 3D design model 30 of a building whose main structure is a railway box 41 is created by linking the sensor model 31 to the measuring equipment 42 using each measurement sensor (IoT sensor) and thereby reflecting the information of the sensing data measured by each measurement sensor, and placing the sensor model 31 at a predetermined location on the 3D design model 30 of the building that requires measurement by the measurement sensor.

[0052] As described above, the construction management device 10 of this embodiment is equipped with a measurement management unit 11 that enables management of construction of a building based on the three-dimensional design data of the three-dimensional design model 30 of the building, which includes the model 30b of the temporary structure, process data for constructing the building, and sensing data measured by a measurement sensor regarding the surrounding ground, temporary structures, or existing structures when constructing the building. The measurement management unit 11 further includes a construction linking unit 15 that associates 3D design data of a predetermined construction portion, preferably divided into work sections, of the 3D design model 30 of the building in which the sensor model 31 is placed with a predetermined process item 33 in the process data; a site situation display unit 16 that displays on a screen data of the site situation as the time axis progresses of a predetermined construction portion, preferably divided into work sections, of the 3D design model 30 of the building in which the sensor model 31 is placed; a measurement data reference unit 19 that references sensing data from the measurement sensor as the time axis progresses during the construction of the predetermined process item 33 based on data regarding the actual start date and time of the predetermined process item 33 in the process data; a control value setting unit 23; a measurement value control value comparison unit 24; a control value memory unit 26; and a control value automatic conversion unit 27.

[0053] In this embodiment, the construction linking unit 15 of the measurement management unit 11 preferably acquires, via the data acquisition unit 17, design data for the 3D design model 30 of the structure in which the sensor model 31 is placed, including the model of the temporary construction section 30b, where the model of the railway box 41, which is the structure, is the main structure model 30a, and the process data, preferably stored in the process data storage unit 13, and associates these to create a 4D model, and also creates a 4D simulation of the planned construction status of the railway box 41, which is the structure, and displays it on a display screen, for example. That is, the construction linking unit 15 associates the design data for the 3D design model 30 of the structure in which the sensor model 31 is placed with the process data to create a 4D model, thereby enabling the planned construction status of the structure, from start to finish, to be displayed on the screen.

[0054] The construction linking unit 15 of the measurement management unit 11 includes a process / status linking unit 15a and a process / model linking unit 15b. As shown in FIG. 8 , the process / status linking unit 15a allows a worker to edit the component status 32 by assigning a different color 32a to each status item, such as "rebar," "formwork," "concrete pouring," "curing," "under construction," "completed," "temporary," "removing," "removed," "not started," "waiting," "not displayed after completion," "cleaning," and "under construction - watermark." The edited results are stored in the component status storage unit 18 of the measurement management unit 11. Furthermore, in the process / status linking unit 15a, for each process item 33 constituting the process data when constructing a predetermined construction portion of a building, preferably divided into work sections, a component status 33a during the process period and a component status 33b after the process period have elapsed can be set in a color-coded state by assigning a different color 32a, and these process items 33 can be linked to the component statuses 33a, 33b during the process period and after the process period have elapsed. The process / status linking unit 15a is configured to perform a component status editing step S4 and a process / status linking step S5, which will be described later.

[0055] 8, the process / model linking unit 15b selects one or more of the process items 33 constituting the process data of the construction, which are displayed as a process schedule for each data of a predetermined construction site, preferably divided into work areas, of the three-dimensional design model 30 of the construction, including the temporary structure model 30b, which is displayed in a hierarchical structure on the screen, and links the data of the predetermined construction site in the three-dimensional design model 30 of the construction to these process items 33. Linking the predetermined construction site in the three-dimensional design model 30 of the construction, including the temporary structure model 30b, to the process items 33 can be easily performed by, for example, including a common number or symbol in the ID number of the process item 33 containing data related to each process item 33 and the ID number of the model (object) included in the data related to the models 30a, 30b, 30c of the structures constituting the three-dimensional design model 30 of the construction, the model 30d of the surrounding ground, etc., via these ID numbers. Furthermore, since the process item 33 is linked to component statuses 33a, 33b during and after the process period in the process / status linking unit 15a (see FIGS. 6 and 9), the component statuses 33a, 33b during and after the process period for each process item 33 can be linked for each data of a specific construction site. The initial status before the start of the process for a specific construction site can also be set. As a result, as each process progresses, the progress of construction for each specific construction site in the 3D design model 30 of the building can be set, for example, by a change in color. The process / model linking unit 15b performs a process / model linking step S6, which will be described later.

[0056] In this embodiment, the measurement data reference unit 19 of the measurement management unit 11 references sensing data managed, for example, in the measurement management system 20, based on data related to the start time of performance of a specific process item 33 in the process data, more specifically, based on data related to the measurement date and time included in the measurement value information from each measuring device 42, preferably at each specific date and time during the construction of the specific process item 33. As a result, the measurement data reference unit 19 has a function to enable the site status display unit 16, described later, to visualize the sensing data referenced by the measurement data reference unit 19, included in the measurement value information, as time-varying data of the site status over time during the construction of the specific process item 33, together with the control value for the process item 33 set by the control value setting unit 23, in real time or as past data on a screen displaying the 3D design model 30 of the building in which the sensor model 31 is arranged. The measurement data reference unit 19 performs a measurement data reference step S10, described later.

[0057] Furthermore, in this embodiment, the measurement management unit 11 includes a control value setting unit 23 that can associate, for example, each of a plurality of process items 33 created by the process data creation unit 22a of the process management device 22 with one or more control values ​​of the control value information included in the control value data of each measuring device 42 managed by the measurement management system 20, and can set or change a control value for each of these process items 33. For example, in association with each process item 33, the control value is reviewed for each measurement sensor (IoT sensor) of a specific measuring device 42 that is required to obtain measurement data during the construction of the process item 33, and the control value setting unit 23 resets or changes the control value for each process item 33 by inputting the control value data preferably by an operator. Furthermore, the control value data set or changed by the control value setting unit 23, related to the sensing data measured by one or more measurement sensors and associated with each specific process item 33, can be stored and saved in the control value storage unit 26. As will be described later, the control value data stored in the control value storage unit 26 is automatically extracted by the control value automatic conversion unit 27 at a predetermined timing when one process item 33 is switched to the next process item 33, and is used as a control value to be compared with sensing data from the measurement sensor in the next process item 33. The control value setting unit 23 is configured to perform a control value setting step S7, which will be described later.

[0058] Here, as construction progresses, it may become necessary to set or change the management values ​​of the measurement values ​​(sensing data) obtained by measuring equipment 42 using a predetermined measurement sensor for each process item 33. For example, in the case where the process item 33 of a predetermined construction site, preferably divided into sections as shown in Fig. 4, is excavation and earth retaining work, and the three-dimensional object at the predetermined construction site in the three-dimensional design model 30 of the building is a strut model as a temporary structure 30b, the management value of the measurement data obtained by a strain gauge attached to, for example, the first strut as a predetermined installation location needs to be changed for each of these more subdivided process items 33 when excavating the ground to construct the first strut and when excavating the ground to construct the second and third struts. For this reason, in this embodiment, for example, an operator inputs control value data for measuring equipment 42 using a specified measurement sensor for each process item 33, as described above, and the control value setting unit 23 stores and preserves the control values ​​set or changed for each of these more detailed process items 33 in the control value memory unit 26.

[0059] Furthermore, for measuring devices 42 using each measurement sensor, the control values ​​set for each predetermined process item 33 may preferably include comparative control values ​​at multiple levels. Six types of comparative control values ​​at multiple levels may be used, for example, the "+1st control value," "+2nd control value," "+3rd control value," "-1st control value," "-2nd control value," and "-3rd control value." Preferably, the comparative control values ​​may be, for example, the design control value multiplied by 0.8 as the primary control value, the design control value itself as the secondary control value, and the design control value multiplied by 1.2 as the tertiary control value (limit control value). For example, the primary control value may be a caution value that does not require immediate countermeasures, preferably encouraging the implementation of countermeasures in advance. For example, the secondary control value may be a tolerance value for the set value, preferably encouraging the implementation of countermeasures immediately. For example, the tertiary control value may be an NG value exceeding the tolerance value, preferably encouraging the stopping of work.

[0060] In this embodiment, the measurement management unit 11 includes a control value storage unit 26 and a control value automatic conversion unit 27. The control value storage unit 26 is configured to store and save control values ​​set for each predetermined process item 33 in the above-mentioned control value setting unit 23, for example, relating to sensing data measured by one or more measurement sensors in the process item 33. The control value storage unit 26 is configured to perform a control value storage step S8, which will be described later.

[0061] The control value automatic conversion unit 27 automatically retrieves the control value to be used for the next process item 33 stored in the control value storage unit 26 at a predetermined timing when one process item 33 switches to the next process item 33, and compares the retrieved control value in the next process item 33 with sensing data from the measurement sensors that accompanies the progress of the time axis during construction of the next process item 33, referenced by the measurement data reference unit 19 based on data related to the performance start date and time of the next process item 33. Here, the predetermined timing at which the control value automatic conversion unit 27 automatically retrieves the control value to be used for the next process item 33 is preferably, for example, the timing at which the performance end date and time of the one process item 33 is input by a worker to the measurement management unit 11 as the performance end point. The predetermined timing at which the control value automatic conversion unit 27 automatically retrieves the control value to be used for the next process item 33 can also be, for example, the timing at which the performance start date and time of the next process item 33 is input by a worker to the measurement management unit 11 as the performance start point. The control value automatic conversion unit 27 performs a control value automatic conversion step S9, which will be described later.

[0062] In this embodiment, the measurement management unit 11 also includes a measurement value control value comparison unit 24. The measurement value control value comparison unit 24 compares the sensing data obtained by the measurement sensors over time during the construction of a specific process item 33, as referenced by the measurement data reference unit 19 based on the data relating to the actual start date and time of the specific process item 33 in the process data, with a control value that is preferably stored in advance in the control value storage unit 26 and retrieved at a predetermined timing by the control value automatic conversion unit 27. The comparison results between the sensing data for each process item 33 compared by the measurement value control value comparison unit 24 and the control value are visualized, for example, by the site status display unit 16 on a screen of a specific construction site in the 3D design model 30 of the building in which the sensor model 31 is placed, together with the sensor model 31, which can reflect the sensing data information. This enables more appropriate management of the construction of the building. The measurement value control value comparison unit 24 performs a measurement value control value comparison step S11, which will be described later.

[0063] The site status display unit 16 of the measurement management unit 11 displays the construction status of a building, preferably at a predetermined construction site divided into work zones, from start to finish, as a 4D model by displaying the 3D design model 30 of the building on a screen. The site status display unit 16 also has a function for visualizing, together with the sensor model 31 capable of reflecting sensing data information, the sensing data from the measurement sensors referenced by the measurement data reference unit 19 in the measurement management system 20 and the sensing data storage unit 14, as site status data over time, along with the control value data (see FIGS. 3 and 4). This allows the site status display unit 16 to simulate and display, on a screen, the construction status of the 3D design model 30 of the building, preferably at a predetermined construction site divided into work zones, over time as each process item 33 progresses, along with the sensor model 31, based on the component statuses 33a, 33b before the start of the process, during the process, and after the process has elapsed, for each process item 33, which is set for each predetermined construction site divided into work zones. This also enables the worker to properly grasp the construction status over time of a predetermined construction portion of the building, which is simulated in four dimensions on the screen by the site status display unit 16. Furthermore, by, for example, clicking and specifying the sensor model 31 on the screen of the predetermined construction portion of the 3D design model 30 of the building in which the sensor model 31 is arranged, the worker can visualize the sensing data measured by the measurement sensor, preferably an IoT sensor, forming the measuring device 42 and referenced by the measurement data reference unit 19 as data on the site status over time, thereby making it possible to easily check the measurement positions measured by the measuring device 42 and more appropriately grasp and manage the site status when constructing the railway box 41, which is a construction, as the main structure.Furthermore, the site status display unit 16 can visualize the comparison results between the sensing data and the control value compared by the measurement value control value comparison unit 24, for example, by displaying the sensing data in different colors 32a depending on whether the sensing data exceeds the set control value or not, or preferably by displaying the sensor model 31 in different colors depending on whether the sensing data exceeds the set control value or not. This makes it possible to more appropriately manage the construction status of a building, preferably in real time, as described above.

[0064] That is, according to this embodiment, the 3D design data (4D design data) linked to the process data of the 3D design model 30 of the construction, including the model 30b of the temporary structure, whose main structure is a railway box 41 installed adjacent to an in-service track 40, is created by linking the sensor model 31, which can reflect information on sensing data measured by the measurement sensors, to the measuring instruments 42 using each measurement sensor, and placing the sensor model 31 at a predetermined location in a predetermined construction site, preferably divided into work areas, in the 3D design model 30 of the construction that requires measurement by the measurement sensors. As a result, for example, by specifying the sensor model 31, the sensing data measured by the measurement sensor, preferably an IoT sensor, and referenced by the measurement data reference unit 19 is displayed together with the sensor model 31 on the screen of the display of the construction management device 10 in a state where the measurement position can be easily grasped, as a time-lapse diagram, list, or the like, together with the management values, and the on-site situation of the construction site can be easily and appropriately managed by the displayed measurement data (see FIGS. 10 and 11). Furthermore, it becomes possible to easily grasp whether the measured value has exceeded the control value, and to more appropriately manage the on-site conditions at the construction site.

[0065] Therefore, according to the construction management device 10 of this embodiment, it is possible to reflect the daily changing site conditions and easily and appropriately grasp the measurement data from measurement sensors such as IoT sensors together with the management values ​​in a 4D model (a model that adds a time axis element based on process data to a 3D model) on the screen of the construction site of a building whose main structure is a railway box 41, thereby managing the site conditions.

[0066] Furthermore, according to this embodiment, the measurement data reference unit 19 preferably directly references sensing data input into the measurement management system 20 from, for example, a measurement sensor, and the sensing data can be displayed on the screen as real-time data of the site situation as the construction of the specified process item 33 progresses along the time axis. This makes it possible to grasp the measurement position on the screen using the sensor model 31 via the sensing data from the measuring devices 42 using each measurement sensor, and to manage the site situation in real time using the control values ​​for each process item 33 set or changed by the control value setting unit 23 and converted by the automatic control value conversion unit 27 according to the progress of construction. This also makes it possible, for example, to issue warning information by the warning information issuing unit 25 (described later) when the sensing data that changes with the progress of construction at a specified location on the construction site where the measuring devices 42 are installed approaches or exceeds the control value converted for each process item 33, so that warning information can be issued to call attention or to suspend work and take countermeasures.

[0067] Furthermore, in this embodiment, a time bar, for example, can be set on a screen displaying a predetermined construction site of the three-dimensional design model (four-dimensional design model) 30 including the model 30b of the temporary structure linked with the process data of each process item 33. This makes it possible to display on the screen the on-site situation accompanying the progress of the predetermined construction site along the time axis of the time bar, together with the transition of the sensing data, and visualize the change in the sensing data over time so that it is easy to grasp on the screen, preferably using a control value, and also makes it possible to display on the screen the sensing data at the specified date and time, preferably together with the control value, by preferably specifying a date and time on the time bar.

[0068] Furthermore, in the construction management device 10 of this embodiment, measurement value information including sensing data of measurement information managed by the measurement management system 20, for example, can be imported and stored in the sensing data storage unit 14 together with measuring instrument information and management value information. This makes it possible to refer to the measurement value information including sensing data together with the management value information as reproducible data by the measurement data reference unit 19, and to use it as reference material when constructing constructions, preferably at other similar construction sites.

[0069] In this embodiment, for example, by clicking and specifying a sensor model 31, the sensing data measured by the sensor, preferably an IoT sensor, related to the sensor model 31 is displayed together with the control value. The data is referenced by the measurement data reference unit 19 and visualized on the screen of the construction management device 10, for example, as a time-series chart or list (see FIGS. 10 and 11). The time-series chart displayed on the screen of the construction management device 10 displays the sensing data of each target measurement sensor in the form of a line graph along a time axis, along with a line representing the control value. The list display displays the measurement values ​​(sensing data) along the time axis for each measurement item. For example, if a measurement value exceeds the control value, the color of the cell in the corresponding column can be changed in stages. Selecting a specific measurement value from the list of measurement values ​​can also transition the measurement value to the sensor model 31 corresponding to the selected measurement value in the model space on the screen.

[0070] In this embodiment, the sensor model 31 arranged at a predetermined construction site of the 3D design model 30 of the building is preferably an icon, simulating a measuring instrument 42. Preferably, the measurement management unit 11 further includes a warning information issuing unit 25. The warning information issuing unit 25 compares the sensing data measured by the measurement sensor with the control value set or changed by the measurement value control value comparison unit 24. When the sensing data exceeds, for example, a secondary control value or a tertiary control value of the comparison control value, the warning information issuing unit 25 issues warning information in real time by gradually changing the color of the icon, which is the sensor model 31, for example, to yellow or red, preferably via the site status display unit 16. Furthermore, the warning information issuing unit 25 can also issue warning information in real time by sound, such as an alarm, when the sensing data measured by the measurement sensor exceeds, for example, a secondary control value or a tertiary control value of the comparison control value.

[0071] In this embodiment, the icon 31 is preferably displayed in an exaggerated form larger than the external shape of the actual measuring device 42 so that the type and installation location can be identified at a glance. The icon, which is a sensor model 31 that imitates the shape of the measuring device 42, can have its color changed by the site situation display unit 16 according to the values ​​of the sensing data and control values ​​measured by the measurement sensor associated with it.

[0072] This allows engineers to easily understand the on-site conditions at the construction site by comparing the 3D design model (4D model) 30 of the construction, which is the main structure model 30a of the railway box 41 and which takes into account the time axis element of the process data displayed on the screen, with the sensing data, which is the measurement values ​​from the measurement sensors, and the trend of its changes over time, while comparing it with the control values, and make appropriate technical decisions. This also makes it possible to centrally manage the sensing data from various measurement sensors on the 3D design model 30 of the construction, making it easy to share sensor information about the installation locations of measuring devices 42 and installed components. Furthermore, by visualizing the sensing data in conjunction with the process information, engineers can easily visually grasp the relationship between the sensing data and the on-site conditions at the construction site, making it easier to interpret these relationships and helping to make technical decisions quickly.

[0073] In the construction management device 10 of this embodiment having the above-mentioned configuration, the measurement management unit 11 can display on the screen, for example, the construction status of a 3D design model 30 of a construction, in which a railway box 41 is the main structure model 30a, preferably of a predetermined construction site divided into work sections, along with sensing data measured by a measurement sensor, preferably an IoT sensor, as the time axis progresses, according to the processing procedure shown in the flowchart of Fig. 5. This allows workers who view this to appropriately manage the construction status at the construction site. The measurement management unit 11 preferably performs processing steps including a data acquisition step S1, a 3D design model import step S2, a process data import step S3, a component status editing step S4, a process / status linking step S5, a process / model linking step S6, a control value setting step S7, a control value storage step S8, a control value automatic conversion step S9, a measurement data reference step S10, a measurement value / control value comparison step S11, and a site status display step S12, so that the construction status of a predetermined construction site, preferably divided into work zones, of a building as the time axis progresses can be displayed on the screen together with sensing data from measurement sensors that can be displayed in association with icons that are sensor models 31. Furthermore, in the site status display step S12, a warning information issuing step S12' can also preferably be performed.

[0074] In the 3D design model import step S2, design data of a 3D design model 30 of a building, preferably of a divided construction site, of a building having a railway box 41 as the main structure, which is created using 3D CAD software and stored in the 3D design data storage unit 12, is acquired from the 3D design data storage unit 12, preferably by the data acquisition unit 17 in a data acquisition step S1, and imported into the measurement management unit 11. The imported design data of the 3D design model 30 of the building is created in a state in which sensor models 31 that can reflect sensing data information by being linked to measuring instruments using each measurement sensor are placed in predetermined locations on the 3D design model 30 of the building that requires measurement by the measurement sensor.

[0075] In the process data import step S3, all process items 33, preferably for the construction sections divided into sections, when constructing a building whose main structure is a railway box 41, which are created using process management software and stored in the process data storage unit 13, are acquired as process data from the process data storage unit 13, for example, by the data acquisition step S1 by the data acquisition unit 17, and imported into the measurement management unit 11.

[0076] In the component status editing step S4, in the process / status linking section 15a of the construction linking section 15, as shown in FIG. 8, a worker operates the screen while looking at the screen to assign a different color 32a to each item of component status 32, such as "rebar," "formwork," "concrete pouring," "curing," "under construction," "completed," "temporary," "removing," "removed," "not started," "waiting," "not displayed after completion," "scraping," "under construction - watermark," "during construction," "after construction period has elapsed," and "initial status before construction begins." This sets the color to be displayed according to the component status 32 when the construction status of a specified part of the building is displayed on the screen using the 3D design model 30 of the building, and edits these component statuses 32.

[0077] In the process / status linking step S5, the process / status linking section 15a of the construction linking unit 15 sets a component status 32 for each process item 33 constituting the process data for constructing a predetermined construction portion, preferably divided into work zones, of a building whose main structure is a railway box 41, according to the processing procedure shown in Fig. 6. That is, in the process / status linking step S5, for example, a worker designates each process item 33, sets a component status 33a during the process period for each of these designated process items 33 (see Fig. 9), and further sets a component status 33b after the process period has elapsed, thereby linking these process items 33 with the component statuses 33a, 33b during and after the process period has elapsed.

[0078] In the process / model linking step S6, the process / model linking unit 15b of the construction linking unit 15 assigns a process item 33 to each selected, predetermined construction portion of the 3D design model 30 of the building, whose main structure is the railway box 41, according to the processing procedure shown in FIG. 7 . That is, in the process / model linking step S6, process data consisting of multiple process items 33 imported into the measurement management unit 11 is read, and design data for the predetermined construction portion of the 3D design model 30 of the building, whose main structure is the railway box 41, is also read. After reading these data, for example, a worker selects a predetermined construction portion of the building to which a process item 33 is to be linked from the design data for the predetermined construction portion of the loaded 3D design model 30 of the building, assigns the process item 33, and sets the initial component status 32, which is the initial state before the construction of the corresponding process item 33 and before the assigned process. The assignment of process items 33 is repeatedly performed for the predetermined portions of all the 3D design models of the building.

[0079] The control value setting step S7 is performed in the control value setting unit 23 described above, and in the control value setting step S7, a control value relating to sensing data measured by one or more measurement sensors in each of the process items 33 is newly set or changed in association with each of the plurality of process items 33 created, for example, by the process data creation unit 22a of the process control device 22.

[0080] The control value storage step S8 is performed in the above-mentioned control value storage unit 26, and in the control value storage step S8, data on the control values ​​related to the sensing data measured by one or more measurement sensors used in each process item 33, which are associated with each specified process item 33 and which have been set or changed in the control value setting step S7, are stored and saved.

[0081] The control value automatic conversion step S9 is performed by the above-mentioned control value automatic conversion unit 27. In the control value automatic conversion step S9, for example, at a predetermined timing when one process item 33 switches to the next process item 33 in a plurality of consecutive process items 33, preferably at the timing when the actual performance end date and time of the one process item 33 is input into the measurement management unit 11 by an operator, the control value to be used for the next process item 33, stored in the control value storage step S8, is automatically retrieved and converted into the control value for the one process item 33. This makes it possible to compare the retrieved and converted control value for the next process item 33 with sensing data from the measurement sensor that accompanies the progress of construction of the next process item 33 over time, referenced by the measurement data reference unit 19 based on data, preferably on the actual performance start date and time of the next process item 33, in the measurement value / control value comparison step S11. The control value automatic conversion step S9 and the measurement data reference step S10, which will be described later, can also be performed in reverse order.

[0082] The measurement data referencing step S10 is performed by the above-mentioned measurement data referencing unit 19, and in the measurement data referencing step S10, based on data relating to the performance start date and time (performance start point) of a predetermined process item 33 in the process data, the sensing data managed in the measurement management system 20 or stored in the sensing data storage unit 14 is referenced, preferably for each predetermined date and time for the predetermined process item 33 currently under construction. As a result, preferably in a site status display step S12 described later, the referenced sensing data can be visualized in real time or as past data on a screen displaying the 3D design model 30 of the building in which the sensor model 31 is placed, together with the control values ​​set in the control value setting step S7 and automatically extracted and converted in the control value automatic conversion step S9, as time-series data of the site status accompanying the progress of the time axis of the predetermined process item 33 currently under construction.

[0083] The measurement value control value comparison step S11 is performed by the measurement value control value comparison unit 24. In the measurement value control value comparison step S11, control values ​​having one or more comparative control values ​​(primary control value to nth-order control value) are acquired for each measurement sensor (IoT sensor) of a predetermined measuring device 42 for which measurement data must be obtained during the construction of the process item 33 in each process item 33 of the process data. The acquired control values ​​are then sequentially compared with the sensing data of the predetermined measuring device 42 measured during the construction of the process item 33, which was referenced in the measurement data reference step S10, to determine whether or not each of the one or more comparative control values ​​has been exceeded. If it is determined that any of the comparative control values ​​has been exceeded, a warning information is issued promptly and appropriately in real time, preferably by changing the color of an icon, for example, the sensor model 31, via a warning information issuance step S12′ in a site status display step S12 described later, to prompt, for example, the construction site to take necessary measures or stop work.

[0084] The site status display step S12 is performed by the above-mentioned site status display unit 16, and in the site status display step S12, the construction status of a construction project having a railway box 41 as the main structure, preferably at a specified construction site divided into work sections, along the time axis from the start to the end of construction associated with process data is reproduced using a three-dimensional design model 30 of the construction project including a sensor model 31 that can reflect information from the sensing data of the construction project, and can be displayed on the screen together with visualized sensing data and control value data (see Figures 10 and 11).

[0085] In this embodiment, the steps from the control value automatic conversion step S9 to the site situation display step S12 are repeatedly performed for each of the plurality of process items 33 in the process data.

[0086] The warning information issuing step S12' is performed by the warning information issuing unit 25, and for example, when the value of the sensing data exceeds the control value set in association with each process item 33, or when the sensing data approaches the set control value, the site status display unit 16 can quickly issue warning information in real time via the sensor model 31 or quickly issue an alarm sound.

[0087] Therefore, the construction management method of the present embodiment for managing the construction of a building using a three-dimensional model analysis program includes measurement management steps (S4, S5, S6, S7, S8, S9, S10, S11, S12) that enable management of the construction of a building from three-dimensional design data of a three-dimensional design model 30 of the building created using a three-dimensional CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors relating to the surrounding ground, temporary structures, or existing structures when constructing the building, and the three-dimensional design data of the three-dimensional design model of the building is linked to measuring equipment 42 using each measurement sensor, thereby enabling management of the sensing data measured by each measurement sensor. The method is created in a state where a sensor model 31 capable of reflecting information is placed at a predetermined location in a three-dimensional design model 30 of a building that requires measurement by the measurement sensor, and the measurement management steps (S4, S5, S6, S7, S8, S9, S10, S11, S12) include a construction linking step (S4, S5, S6) that associates design data of a predetermined construction portion of the three-dimensional design model 30 of the building in which the sensor model 31 is placed with a predetermined process item 33 in the process data, and a site situation display step (S12) that displays on a screen data of the site situation as the time axis progresses for the predetermined construction portion of the three-dimensional design model 30 of the building in which the sensor model 31 is placed, andThe control value storage step (S12) further includes a control value storage step (S8) and a control value automatic conversion step (S9). The control value storage step (S8) stores, for each predetermined process item 33, a control value set for sensing data measured by one or more measurement sensors in the process item 33. The control value automatic conversion step (S9) automatically extracts the control value to be used in the next process item 33 stored in the control value storage step (S8) at a predetermined timing when one process item 33 is switched to the next process item 33, and converts the control value to the next process item 33. The extracted control value is compared with the sensing data from the measurement sensor as the time axis progresses during the construction of the next process item 33, which is referenced based on the data regarding the actual start date and time of the next process item 33. In the site status display step (S12), the results of the comparison between the compared sensing data and the control value are visualized on the screen of a predetermined construction site of the 3D design model in which the displayed sensor model 31 is arranged, along with the sensor model 31 that can reflect the information of the sensing data, thereby making it possible to manage the construction of the building.

[0088] The construction management device 10 of this embodiment is a construction management program for managing construction of a building using a 3D model analysis program, and causes a computer to execute measurement management steps (S4, S5, S6, S7, S8, S9, S10, S11, S12) that enable management of construction of a building based on 3D design data of a 3D design model of the building created using a 3D CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors relating to the surrounding ground, temporary structures, or existing structures when constructing the building. The 3D design data of the 3D design model of the building is linked to measuring equipment using each measurement sensor, thereby enabling management of construction of the building based on the data of each measurement sensor. The sensor model 31 capable of reflecting information of sensing data measured by the measurement sensor is created in a state where it is placed in a predetermined portion of a three-dimensional design model that requires measurement by the measurement sensor, and in the measurement management steps (S4, S5, S6, S7, S8, S9, S10, S11, S12), a construction linking step (S4, S5, S6) of associating design data of the predetermined portion of the three-dimensional design model in which the sensor model 31 is placed with a predetermined process item 33 in the process data, and a site situation display step (S12) of displaying on a screen data of the site situation as the time axis progresses for the predetermined portion of the three-dimensional design model in which the sensor model 31 is placed, are caused to execute by a computer, and the measurement management steps (S4, S5, S6, S7, S8, S9, S10, S11,In step S12), the computer further executes a control value storage step (S8) for storing, for each predetermined process item 33, a control value set for the sensing data measured by one or more measurement sensors in that process item 33, and a control value automatic conversion step (S9) for automatically retrieving the control value to be used in the next process item 33 stored in the control value storage unit 26 at a predetermined timing when one process item 33 switches to the next process item 33, and for the next process item 33, comparing the retrieved control value with the sensing data from the measurement sensor as the time axis progresses during the construction of the next process item 33, referenced based on data relating to the actual start date and time of the next process item 33.In the site status display step (S12), the comparison result between the compared sensing data and the control value is visualized on the screen of a predetermined construction site of the 3D design model in which the displayed sensor model 31 is arranged, together with the sensor model 31 that can reflect the sensing data information, thereby enabling construction of the building to be managed.

[0089] The present invention is not limited to the above-described embodiments and various modifications are possible.

The data acquisition unit can directly acquire 3D design data and process data from a 3D design device, a process management device, or a measurement management system. The 3D design data and process data can also be imported into the measurement management unit without going through the data acquisition unit. The measurement sensor does not necessarily need to be an IoT sensor, and can be any of various other well-known sensors that make up various types of measurement equipment. [Explanation of symbols]
