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 front-loading, which allows for work transformation by switching from 2D drawings to 3D models when constructing various structures, or by focusing on early processes (front-loading) and prioritizing intensive consideration in advance to prevent rework that may occur in later processes, thereby 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, enabling the creation of 4D models that incorporate time-based elements into 3D graphically displayed 3D models of buildings, for example, at construction sites, thereby enabling easy 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).

Koyama, N. Yabuki, and T. Fukuda: Journal of the Japan Society of Civil Engineers, Proceedings of the JSCE F3 (Civil Engineering Informatics), Vol. 77, No. 2, pp. 1_97-1_113, 2021. 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 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 on-site conditions that change daily and enable easy and appropriate understanding of measurement data from measurement sensors such as IoT sensors in a four-dimensional model of the construction site, thereby managing the on-site conditions.

DETAILED DESCRIPTION OF THE INVENTION

[0024] 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, and visualizes the sensing data in a 4D model, preferably associated with a 3D model based on BIM / CIM and process data based on a process management program, to display or reproduce the site situation in real time. The construction management device 10 of this embodiment has the functionality to easily and appropriately manage measurement data (sensing data), preferably from IoT sensors, in a 4D model of the construction site of a building under construction, which reflects the daily changing site situation with process data.

[0025] 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.

[0026] 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.

[0027] The measurement management unit 11 includes a construction linking unit 15 that associates 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. 9 and 10) that requires measurement by a measurement sensor, for example, and a site status display unit 16 that displays on a screen data of the site status over time of the predetermined construction portion of the 3D design model 30 of the building in which the sensor model 31 is arranged. The measurement management unit 11 also includes a measurement data reference unit 19 that references sensing data by the measurement sensor over time during the construction of the predetermined process item 33 based on data related to the performance start date and time, which is the start time of performance of the predetermined process item 33 in the process data. The site situation display unit 16 visualizes the sensing data measured by a measurement sensor, preferably an IoT sensor, referenced by the measurement data reference unit 19, together with the sensor model 31 that can reflect the sensing data information on the screen of a specified construction site of the 3D design model 30 of the building on which the displayed sensor model 31 is placed, as data on the site situation over time (see Figures 3 and 4), thereby enabling management of the construction of the building.

[0028] In this embodiment, the sensing data, preferably from an IoT sensor, referenced by the measurement data reference unit 19 may be data in the measurement management system 20 described later, or may be data stored in the sensing data storage unit 14.

[0029] Furthermore, the construction management device 10 for a building 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.

[0030] 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.

[0031] 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 information. The 3D model analysis program can provide the software side with a development environment for implementing 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, and a warning information issuing unit 24, which will be described later. An example of a 3D model analysis program (3D model analysis software) that can provide such a development environment to the software side is the software "PADMS" manufactured by Pasco Corporation.

[0032] 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 condition may be created by a 3D design model creation unit 21a using a known 3D CAD program incorporated in the construction management device 10, and may be stored in the 3D design data storage unit 12.

[0033] Preferably, "Revit" by Autodesk, a BIM tool capable of creating BIM models, can be used as a 3D CAD program (3D CAD software) for incorporating the 3D design model creation unit 21a into the 3D design device 21. In the 3D design model 30 of the building's on-site situation created by the 3D design model creation unit 21a, as will be described later, sensor models 31 (see FIGS. 3 and 4) can reflect information on sensing data measured by measurement sensors, preferably sensor models 31 made up of icons imitating the shapes of measuring devices 42 using each measurement sensor, and are arranged as 3D objects at predetermined locations that require measurement by the measurement sensors.

[0034] 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.

[0035] 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. 9) when constructing each of the divided construction sites, information on at least 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 site.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In this embodiment, the design data for the 3D design model 30 of the building, which is preferably stored in the 3D design data storage unit 12 and created by, for example, the 3D design model creation unit 21a of the 3D design device 21, includes, as 3D objects, data on the main structure model 30a, which is a model of the railway box 41 of the building, the temporary structure model 30b, the existing structure model 30c, the surrounding ground model 30d, etc., as described above, and the design data for each of these structure models 30a, 30b, 30c and surrounding ground model 30d, etc., is assigned management information such as the ID number, file path, node path, etc. of each model (object). The design data for each sensor model 31 created as a 3D object by the 3D design model creation unit 21a is also assigned management information such as the ID number, file path, node path, etc. of the measuring instrument 42 (see FIG. 1).

[0040] 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). Furthermore, when actually carrying out construction, information regarding the actual start date and time and actual end date and time for each of the multiple process items 33 at each of the divided construction sites, preferably during the construction of the railway box 41 as a main structure, can be added by, for example, a worker inputting into the construction management device 10, information regarding the actual start date and time for a specific process item 33 in the process data. By assigning data relating to the actual start date and time, particularly the start date and time, of information relating to the actual start date and time and the end 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 by 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 actual start date and time. This makes it possible to include sensing data, preferably from an IoT sensor, included in the measurement value information in the data on 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.

[0041] 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 value data and management value data. The measurement value 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, etc.), 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.

[0042] 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.

[0043] On the other hand, the control value data indicates the threshold value of the measurement value (sensing data) from the measurement sensor, and can be used to perform management such as issuing a warning when the measurement value exceeds the control value. By linking the measurement value data and the control value data in the construction management device 10, it becomes possible to more appropriately manage the measurement values ​​(sensing data) in the 3D design model 30 of the building displayed on the screen, including the sensor model 31.

[0044] The control value data includes not only the same measuring instrument information as the measurement value data, but also control value information. 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, and the node path. 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 appropriately set or change the value of the control value to be applied according to the reference date and time. Six types of control values ​​can be used, for example, "+primary control value," "+secondary control value," "+tertiary control value," "-primary control value," "-secondary control value," and "-tertiary control value." Preferably, the control value can be, for example, a primary control value of 0.8 times the design value, a secondary control value of the design value itself, and a tertiary control value (limit control value) of 1.2 times the design value.

[0045] According to this embodiment, measurement value information such as sensing data contained in measurement value 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.

[0046] 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.

[0047] 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 the 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; and a measurement value / control value comparison unit.

[0048] 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 can also perform a 4D simulation of the planned construction status of the railway box 41, which is the structure, and display 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.

[0049] 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. 6, 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," or "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 different colors 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.

[0050] 10, 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 in 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 FIG. 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. In addition, 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.

[0051] 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 actual start date and time 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 that enables 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 S7, described later.

[0052] 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 sections, from start to finish, as a 4D model on a screen by displaying the 3D design model 30 of the building as a 4D model. The site status display unit 16 also has a function of visualizing, together with a sensor model 31 capable of reflecting sensing data information, sensing data from 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 (see FIGS. 3 and 4). This enables 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 sections, along with the sensor model 31, over time as each process item 33 progresses. 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.

[0053] 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 zones, in the 3D design model 30 of the construction that requires measurement by the measurement sensors. As a result, for example, by clicking on 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 in the measurement management system 20 or the sensing data storage unit 14, together with the sensor model 31, is displayed as a time-lapse diagram, list, or the like on the screen of the display of the construction management device 10 in a state where the measurement position can be easily grasped, and the on-site situation of the construction site can be easily and appropriately managed by the displayed measurement data (see FIGS. 11 and 12).

[0054] Therefore, according to the construction management device 10 of this embodiment, it is possible to easily and appropriately grasp measurement data from measurement sensors such as IoT sensors and manage the site conditions by reflecting the site conditions that change daily and 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.

[0055] Furthermore, according to this embodiment, the measurement data reference unit 19 preferably directly references sensing data imported into the measurement management system 20 from, for example, a measurement sensor via a wired or wireless network, etc., and the sensing data can be displayed on the screen as real-time data on the site situation as the construction of the specified process item 33 progresses along the timeline. This makes it possible to manage the site situation in real time according to the progress of construction, while grasping the measurement position on the screen using the sensor model 31 via the sensing data from the measuring devices 42 using each measurement sensor. Furthermore, this makes it possible, for example, to issue warning information by the warning information issuing unit 24 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 a control value set or changed by the control value setting unit 23 described later, for example, so that warning information can be issued by the warning information issuing unit 24 described later to call attention or to suspend work and take countermeasures.

[0056] Furthermore, in this embodiment, a time bar, for example, can be set on a screen displaying a predetermined construction site of the 3D design model (4D design model) 30 of the building, which includes the model 30b of the temporary structure linked to the process data of each process item 33. This makes it possible to display on the screen along the time axis of the time bar the site situation accompanying the progress of the predetermined construction site together with the transition of the sensing data based on the measurement date and time of the measurement value information, and visualize the change in the sensing data over time so that it is easy to grasp on the screen, and preferably by specifying a date and time on the time bar, it becomes possible to display on the screen the sensing data at the specified date and time, preferably together with the control value.

[0057] 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.

[0058] To use measurement information including the measurement date and time and sensing data as reference material when constructing buildings at other similar construction sites, for example, as shown in FIG. 8, the site status display unit 16 of the measurement management unit 11 preferably displays a data image of the overall construction status of the construction site, and then specifies the date and time to display in the displayed data image. This makes it possible to display measurement information including sensing data for the relevant date and time during that period referenced by the measurement data reference unit 19 on the same screen as the data image of the construction status at the specified date and time. In addition, it is possible to display only measurement information on the screen. For example, by specifying a location to display on a screen displaying only measurement information, it becomes possible to display a three-dimensional model of the specified location together with surrounding construction information, management value information, measurement value information, etc.

[0059] Furthermore, in this embodiment, the measurement management unit 11 preferably includes a control value setting unit 23 that can set or change one or more control values ​​of the control value information included in the control value data from each measuring device 42, as well as the application dates of these values. This makes it possible for the above-mentioned site situation display unit 16 to visualize, on the screen of a predetermined construction site of the 3D design model 30 of the building in which the sensor model 31 is arranged, the sensing data measured by the measurement sensor, via the sensor model 31 that can reflect the sensing data information, together with control value data based on one or more control values ​​set or changed by the control value setting unit 23 in accordance with the site situation, thereby enabling more appropriate management of the construction of the building.

[0060] In other words, one or more control values ​​of the control value information may be changed or added as the construction progresses, and it may become necessary to reset these control values, along with the application date and time, from those at the time of planning.For example, as shown in Figure 4, if the process item 33 of a predetermined construction site, preferably divided into work sections, is excavation and retaining work, and the three-dimensional object at the predetermined construction site in the three-dimensional design model 30 of the building is a model of a strut as a temporary structure 30b, the control value of the measurement data from a strain gauge attached to, for example, the first strut as a predetermined installation location needs to be changed between excavating the ground when constructing the first strut and excavating the ground when constructing the second and third struts. For this reason, for example, when a worker inputs data relating to the actual start date and time of a specific process item 33 in the process data into the construction management device 10 as described above, one or more control values ​​to be set or changed at the same time are input into the construction management device 10 along with their application dates, and these are assigned to the control value information of the measurement information, so that the control value is reset from what it was at the time of planning according to the application date and time.

[0061] The data on the application date of the set or changed control value is preferably referenced by the measurement data reference unit 19 together with measurement value information including sensing data, and can be visualized on a screen as chronological data that can be displayed on the time axis of the building under construction, preferably together with sensing data from an IoT sensor. The control value setting unit 23 is configured to perform a control value setting step S7', which will be described later.

[0062] In this embodiment, for example, by clicking and specifying a sensor model 31, the sensing data measured by a measurement sensor, preferably an IoT sensor, related to the sensor model 31 is displayed along with one or more control values. The data is referenced by the measurement data reference unit 19 and visualized on the screen of the construction management device 10 as, for example, a time-series chart or a list (see FIGS. 11 and 12). The time-series chart displayed on the screen of the construction management device 10 displays the sensing data and control values ​​of each target measurement sensor in the form of a line graph along a time axis. The list display displays the measurement values ​​(sensing data) along the time axis for each measurement item. For example, if a measurement value exceeds a 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.

[0063] The site status display unit 16 can also visualize sensing data in different colors for values ​​that exceed a set or changed control value and values ​​that do not exceed a set or changed control value, for example, in a list. The site status display unit 16 can also visualize control value data for two or more set or changed control values ​​in different colors, for example, in a time-series diagram. The site status display unit 16 can also visualize sensing data together with two or more set or changed control value data for each specified date and time. These make it possible to more easily and appropriately grasp measurement data (sensing data) from measurement sensors such as IoT sensors referenced by the measurement data reference unit 19 and manage the site status.

[0064] In this embodiment, the sensor model 31 placed at a predetermined construction site of the 3D design model 30 of the building is preferably an icon as a sensor model in the form of a measuring instrument, and preferably the measurement management unit 11 further includes a warning information issuing unit 24. The warning information issuing unit is capable of issuing warning information in real time via the icon that is the sensor model 31 when the sensing data measured by the measurement sensor exceeds, for example, a control value set or changed by the control value setting unit 23.

[0065] In this embodiment, the icon representing the sensor model 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 representing the sensor model 31, which imitates the shape of the measuring device 42, can be changed in color by the site status display unit 16 in accordance with the value of sensing data measured by the associated measurement sensor. As a result, when, for example, the value of the sensing data exceeds a set management value, the warning information issuing unit 24 can promptly issue visual warning information via the sensor model 31 in real time by causing the site status display unit 16 to change the color of the sensor model 31, for example, to red. Furthermore, when, for example, the sensing data approaches a set management value, the warning information issuing unit 24 can promptly issue visual warning information via the sensor model 31 in real time by causing the site status display unit 16 to change the color of the sensor model 31, for example, to yellow.

[0066] This allows engineers to easily grasp the on-site conditions of the construction site and make appropriate technical decisions based on the 3D design model (4D design model) 30 of the construction, which is a model 30a of the main structure (railway box 41) that takes into account the time axis element of the process data displayed on the screen, and the sensing data, which is the measurement values ​​from the measurement sensors, and the trend of its changes over time. 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 of the construction site, making it easier to interpret these relationships and helping to make technical decisions quickly.

[0067] In the construction management device 10 of this embodiment, the measurement management unit 11 can display the construction status of a 3D design model 30 of a building, preferably divided into sections, of a main structure model 30a, such as a railway box 41, on a screen, preferably according to the processing procedure shown in the flowchart of FIG. 5, along with sensing data measured by a measurement sensor, preferably an IoT sensor, as the time axis progresses. This allows workers viewing the display to appropriately manage the construction status at the construction site. The measurement management unit 11 can display the construction status of a 3D design model 30 of a building, preferably divided into sections, of a main structure model 30a, along with sensing data measured by a measurement sensor, preferably an IoT sensor, as the time axis progresses, along with sensing data measured by a measurement sensor, preferably an IoT sensor, as the time axis progresses. The measurement management unit 11 can display the construction status of a 3D design model 30 of a building, preferably divided into sections, on a screen, preferably according to the processing procedure shown in the flowchart of FIG. 5, along with sensing data measured by a measurement sensor, preferably an IoT sensor, as the time axis progresses. Furthermore, it is also possible to preferably carry out a control value setting step S7' prior to the measurement data reference step S7, and it is also possible to preferably carry out a warning information issuing step S8' in the site situation display step S8.

[0068] 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 devices 42 using each measurement sensor are placed in predetermined locations on the 3D design model 30 of the building that requires measurement by the measurement sensors.

[0069] 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.

[0070] In the component status editing step S4, in the process / status linking section 15a of the construction linking section 15 described above, as shown in FIG. 9, the worker operates the screen while looking at the screen to assign different colors 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 period," "after construction period has elapsed," and "initial status before construction begins." This allows the color to be set according to the component status 32 when the construction status of a specific part of the building is displayed on the screen using the 3D design model 30 of the building, and these component statuses 32 to be edited.

[0071] 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, the worker specifies each process item 33, sets a component status 33a during the process period for each specified process item 33 (see Fig. 10), 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.

[0072] 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, the process data consisting of multiple process items 33 imported into the measurement management unit 11 is read, and the design data of 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 the process item 33 is to be linked from the design data of the predetermined construction portion of the 3D design model 30 of the building, assigns the process item 33, and sets the initial component status, which is the initial state before the construction of the corresponding process item 33 and before the assigned process. The process item 33 is repeatedly assigned to all predetermined portions of the 3D design model 30 of the building.

[0073] In the measurement data reference step S7, sensing data relating to the surrounding ground, temporary structures, existing structures, etc. when constructing a building having a railway box 41 as the main structure, which is obtained via the measurement management system 20 and stored in the sensing data storage unit 14, is acquired as measurement data from the measurement data storage unit 14, for example, by the data acquisition unit 17 in data acquisition step S1, and is taken into the measurement management unit 11. Furthermore, the above-mentioned measurement data reference unit 19 references sensing data managed by the measurement management system 20 or stored in the sensing data storage unit 14, preferably for each predetermined date and time for the predetermined process item 33 during construction, based on data relating to the actual start date and time of the predetermined process item 33 in the process data. This makes it possible to visualize the sensing data referenced in the measurement data reference step S7, which is included in the measurement value information, in real time or as past data on a screen displaying the 3D design model 30 of the building on which the sensor model 31 is placed, as time-varying data of the site situation as the time axis of a specified process item 33 during construction progresses, preferably in the site situation display step S8 described below.
