Description

Technical Field

[0001] The present invention relates to a construction management apparatus for a building, a construction management method for a building, and a construction management program that manage the construction of a building using a three-dimensional model analysis program.

Background Art

[0002] In recent years, in the field of civil engineering and public works such as bridges, tunnels, dams, geotechnical engineering, and rivers, when constructing various buildings, there has been a business transformation from two-dimensional drawings to three-dimensional models, or a load is applied in the initial process (front) and concentrated consideration is carried out in advance to prevent potential setbacks in the subsequent process, enabling quality improvement and construction period shortening. By means of front-loading, the Ministry of Land, Infrastructure, Transport and Tourism aims to accelerate consensus formation, improve business efficiency, improve quality, and ultimately improve productivity. Therefore, various three-dimensional model analysis programs and software for creating three-dimensional CIM models have been developed.

[0003] Also, mainly for building structures, different from conventional 3DCAD which creates a two-dimensional drawing and then assembles a three-dimensional shape for CG simulation, BIM (Building Information Modeling) models that can be designed in three dimensions from the beginning and create three-dimensional models have been developed. In a BIM model, since it is an aggregate of three-dimensional objects, it is possible to add attribute data such as cost, finish, and management information to these objects, and it becomes possible to utilize the information accumulated in the model throughout the entire life cycle of the building, from design and construction to maintenance management. As BIM tools capable of creating BIM models, various three-dimensional CAD software such as "ArchiCAD" and "Revit" are known.

[0004] Furthermore, various process management softwares are known for managing, for example, the planning and implementation of processes in public works so that the construction is completed within a defined construction period. Also, by combining three-dimensional CAD software capable of creating BIM models and CIM models with process management software, a construction management device for a building has been developed that enables, for example, at a construction site, the formation of a four-dimensional model that adds an element of time axis to a three-dimensional model of a building displayed in 3D graphics and facilitates four-dimensional simulation (see, for example, Patent Document 1). The Ministry of Land, Infrastructure, Transport and Tourism has made an attempt to apply the function of four-dimensional simulation over time using such a four-dimensional model to three-dimensional BIM models and CIM models as well and expand it to the field of civil engineering and public works (see, for example, Non-Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

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

[0008] Here, the measurement sensor preferably the IoT sensor is a sensor that can be connected to a network to collect and manage information, enabling the utilization of the collected information for real-time monitoring of various on-site situations, predictive maintenance, prognostic monitoring, data accumulation, quality improvement, etc. Even at the construction site of a building such as civil engineering public works, preferably by using measurement sensors such as IoT sensors, it becomes possible to streamline various measurement operations, and by automatically collecting measurement data (sensing data) by the sensors, it is considered possible to significantly reduce the labor required for managing and monitoring the building and the on-site situation around it. On the other hand, at the construction site of a building, there is a concern that new labor will be required for the management of measurement data by measurement sensors such as IoT sensors.

[0009] That is, at the construction site of a building, as the construction progresses, the site conditions change with the passage of time due to daily construction work. Sometimes, due to the movement or change of the installation position of sensors, such as the replacement of measurement sensors like IoT sensors, fluctuations in measurement data caused by factors unrelated to the measurement items are likely to occur. For this reason, when engineers appropriately grasp the site conditions from the fluctuations in the values of the measurement data and determine countermeasures, it becomes difficult to interpret the relationship between the site conditions that change over time and the measurement data based only on the measurement data from measurement sensors such as IoT sensors, and thus it is difficult to appropriately determine countermeasures. Also, for example, in the case of measurement items where a warning is set to be issued to engineers when the measurement data exceeds the management value, it becomes necessary to routinely manage the measurement data from measurement sensors such as IoT sensors and reset the management value of the relevant measurement item as the construction progresses. This also requires a great deal of effort for tasks such as data arrangement for this purpose.

[0010] In contrast, for example, by centrally managing the measurement data from various sensors on a 3D model using BIM / CIM, the relevance between the sensor information and the site conditions can be visually and easily grasped by engineers by visualizing the sensor information at predetermined locations or on members of the building (see, for example, Non-Patent Document 2). According to Non-Patent Document 2, regarding the association between the 3D model and the sensor information, the development of a bridge data model, a sensor data model, and a linkage data model for linking them has been carried out. By using the developed linkage data model, the sensor data can be associated with the data model of the bridge, which is a building, and managed on the 3D model.

[0011] However, according to the method of associating and managing the sensor data described in Non-Patent Document 2 with the data model of a building, the linked data model is assumed to use sensors mainly for monitoring for maintenance purposes for sensors installed in existing buildings. Therefore, it is not assumed for a construction site of a building where the site situation frequently changes with the passage of time during monitoring, so it is difficult to appropriately grasp the measurement data by measurement sensors such as IoT sensors together with management values in the 4D model of the construction site of the building and manage the site situation so as to reflect the daily changing site situation.

[0012] An object of the present invention is to provide a construction management device for a building, a construction management method for a building, and a construction management program for a building, which make it possible to easily and appropriately grasp measurement data by measurement sensors such as IoT sensors together with management values in a 4D model of a construction site of a building and manage the site situation so as to reflect the daily changing site situation.

The measurement management unit further includes a measurement data reference unit and a measured value management value comparison unit. The measured value management value comparison unit compares the sensing data measured by the measurement sensor along the progress of the time axis during the construction of the predetermined process item, referred to by the measurement data reference unit based on data regarding the actual start time of the predetermined process item in the process data, with a management value set for each predetermined process item. The site condition display unit visualizes the comparison result between the sensing data and the management value compared by the measured value management value comparison unit, together with the sensor model capable of reflecting the information of the sensing data, on the screen of the predetermined construction site of the three-dimensional design model where the displayed sensor model is arranged, so as to manage the construction of the building. By providing the construction management device of the building that achieves the above object.

[0014] Moreover, it is preferable that the construction management device of the present invention includes a management value set for each of the predetermined process items, which consists of comparison management values at multiple levels.

[0015] Furthermore, when the measurement value management value comparison unit of the construction management device of the present invention determines that the sensing data from the measurement sensor exceeds any of the comparison management values at multiple levels, it is preferable to issue a warning message to enable the corresponding measures at the site to be changed at each level.

[0016] Moreover, it is preferable that the on-site situation display unit of the construction management device of the present invention can visualize the comparison results in different colors depending on whether the sensing data exceeds the set management value or not.

[0018] Furthermore, it is preferable that the sensing data referred to by the measurement data reference unit of the construction management device of the present invention is data in the measurement management system.

[0019] Moreover, it is preferable that the sensor model of the construction management device of the present invention is an icon imitating the shape of the measuring instrument using each of the measurement sensors.

[0020] Furthermore, it is preferable that the measurement sensor of the construction management device of the present invention is a sensor constituting a settlement gauge, an inclinometer, a strain gauge, a displacement gauge, a water level gauge, a distance gauge, or a thermometer.

[0021] Also, it is preferable that the measurement sensor of the construction management device of the present invention is an IoT sensor.

[0022] Furthermore, it is preferable that the sensing data measured by the measurement sensor is data related to displacement, change, or load in the construction management device of the present invention.

In the measurement management step, it further includes a measurement data reference step and a measured value management value comparison step. In the measured value management value comparison step, based on the data regarding the actual start time of the predetermined process item in the process data, the sensing data measured by the measurement sensor as the time axis progresses during the construction of the predetermined process item, which is referred to by the measurement data reference step, is compared with the management value set for each predetermined process item. In the site status display step, on the screen of the predetermined construction site of the three-dimensional design model where the displayed sensor model is arranged, by visualizing the comparison result between the sensing data and the management value compared by the measured value management value comparison step together with the sensor model capable of reflecting the information of the sensing data, a construction management method for a building that enables the management of the construction of the building is provided, thereby achieving the above object.

[0027] The construction management device 10 according to a preferred embodiment of the present invention shown in FIG. 1 is, for example, in the construction of a railway box body 41 to be constructed underground as a building near an in-service track 40 in a railway underground project (see FIG. 2). In order to quickly confirm the impact on the in-service track 40 due to the construction, various measuring devices 42 (see FIGS. 3 and 4), preferably measurement sensors such as IoT sensors, are installed at various locations on the construction site. For example, the displacement of temporary earth retaining, the displacement of the construction base surface of the track, the displacement of existing tram line facilities, the displacement of surrounding buildings and ground, etc. are measured as measurement items together with the measurement date and time, so as to appropriately grasp and manage the on-site situation of the construction site. It is preferably used as a management device by a computer. The construction management device 10 of the present embodiment collectively manages the data measured by the measuring device 42 preferably using an IoT sensor installed at a predetermined location or member at the construction site. From the measurement management system 20 (see FIG. 1), for example, the sensing data (measurement data) output in CSV format is referred to together with the measurement date and time, or taken into the sensing data storage unit 14 as post-conversion data. In a 4D model in which the association between a 3D model by BIM / CIM and process data by a process management program is performed, the sensing data can be visualized together with the management value, and the on-site situation can be displayed and reproduced in real time. The construction management device 10 of the present embodiment has a function of comparing the measurement data (sensing data) preferably by an IoT sensor with the management value in a 4D model of the construction site of the building under construction, which reflects the daily changing on-site situation by the process data, so that it can be easily and appropriately managed.

[0028] 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 incorporated in a computer. As shown in FIG. 1, it includes 3D design data of a 3D design model 30 of a building, preferably including a model 30b of a temporary structure (see FIG. 4) created using a 3D CAD program, process data for constructing the building created using a process management program, and preferably sensing data regarding the surrounding ground, temporary structures, or existing structures during the construction of the building measured by a measurement sensor using an IoT sensor.

[0029] The 3D design data of the 3D design model 30 of the building is created in a state where a sensor model 31 capable of reflecting the information of the sensing data measured by each measurement sensor is arranged at a predetermined location of the 3D design model 30 of the building that requires measurement by the respective measurement sensors, by being associated with a measuring device 42 using a measurement sensor of each IoT sensor.

[0030] 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 and a measurement value control value comparison unit 24. The measurement value control value comparison unit 24 compares the sensing data by the measurement sensor over time 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 set for each predetermined process item 33. The site situation display unit 16 visualizes the results of the comparison between the sensing data and the control value compared by the measurement value control value comparison unit 24, 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, thereby enabling the construction of the building to be managed.

[0031] In this embodiment, the sensing data, preferably from 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.

[0032] 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.

[0033] 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 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an I / F (Interface), an HDD (Hard Disk Drive), a storage means, an input means, a display means, an output means, and the like. The CPU controls the overall operation of the construction management device 10 while using the RAM as a work area according to various control programs incorporated in the ROM. Further, since various computer programs are incorporated in the ROM, the CPU functions the storage means, the input means, the display means, the output means, etc., and, for example, a model 30a of the main building of a building (see FIG. 3), a model 30b of a temporary building (see FIG. 4), a model 30c of an existing building (see FIG. 3), a model 30d of the surrounding ground (see FIG. 3), etc., various data such as 3D design data of a 3D design model 30 of a building including them as 3D objects, process data, and sensing data can be stored in a database section forming the storage units 12, 13, 14 by the storage means, or predetermined information can be displayed on a screen such as a display by the display means, or output from a printer or the like by the output means.

[0034] And in this embodiment, a known three-dimensional model analysis program is incorporated in the construction management device 10 by the computer, and the three-dimensional model analysis program has functions for creating a three-dimensional model, point cloud display, obtaining and analyzing information, etc. The three-dimensional model analysis program can provide a software-side development environment for implementing a measurement management section 11 and the like including various storage units 12, 13, 14, a data acquisition section 17, a construction association section 15, a measurement data reference section 19, a site situation display section 16, a management value setting section 23, a measurement value management value comparison section 24, and a caution information issuing section 25, which will be described later. As such a three-dimensional model analysis program (three-dimensional model analysis software) that can provide such a development environment on the software side, for example, software "PADMS" manufactured by Pasco Co., Ltd. can be used.

[0035] 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 of a three-dimensional design model 30 of the building at the construction site, including a model 30a of the main body structure (see FIG. 3), a model 30b of the temporary structure (see FIG. 4), a model 30c of the existing structure (see FIG. 3), a model 30d of the surrounding ground (see FIG. 3), etc., of the railway box 41 which is a building installed near the in-service track 40 and is constructed with the main body structure when constructed using a three-dimensional CAD program. The design data of the three-dimensional design model 30 of the building at the construction site 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 different from the construction management device 10, and taken 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 three-dimensional design model 30 of the building at the construction site including the model 30b of the temporary structure may be created by the three-dimensional design model creation unit 21a using a known three-dimensional CAD program incorporated in the construction management device 10 and stored in the three-dimensional design data storage unit 12.

[0036] Preferably, as the three-dimensional CAD program (three-dimensional CAD software) for incorporating the three-dimensional design model creation unit 21a into the three-dimensional design device 21, for example, "Revit" manufactured by Autodesk, which is a BIM tool capable of creating a BIM model, can be preferably used. In the three-dimensional design model 30 of the building at the construction site including the model 30b of the temporary structure created by the three-dimensional design model creation unit 21a, as will be described later, a sensor model 31 (see FIGS. 3 and 4) in the form of an icon simulating the shape of the measuring instrument 42 using each measuring sensor, which can reflect the information of the sensing data measured by the measuring sensor, is arranged as a three-dimensional object at a predetermined location that requires measurement by the measuring sensor.

[0037] In addition, in the present embodiment, the construction management device 10 includes a process data storage unit 13. The process data storage unit 13 stores process data when constructing a railway casing 41, which is a building constructed adjacent to the in-service track 40, using the process management program with the main body structure. The process data when constructing the railway casing 41, which is a building, can be created by a process data creation unit 22a in a known process management program incorporated in a process management device 22 different from the construction management device 10, and then taken into the construction management device 10 via, for example, a storage medium or a wired or wireless communication network and stored in the process data storage unit 13. The process data when constructing the railway casing 41, which is a building, may be created by the process data creation unit 22a in a known process management program incorporated in the construction management device 10 and stored in the process data storage unit 13.

[0038] Preferably, as the process management program (process management software) for incorporating the process data creation unit 22a into the process management device 22, for example, "Being Project - CCPM" manufactured by Being Co., Ltd., which is a program equipped with a CCPM (Critical Chain Project Management) function, can be preferably used. The process data created by the process data creation unit 22a includes, for example, information on at least the order of each of the plurality of process items 33 (see FIG. 8) when constructing each construction site divided by work sections, and the process period consisting of the planned start date and planned end date of the process. The process items 33 consist of items such as steel bar assembly, scaffold assembly, shoring assembly, formwork assembly, and removal of temporary materials (scaffolds, shoring, formwork) for each predetermined construction site.

[0039] Here, the process management program preferably equipped with the CCPM function is a process management software (process management program) that adopts Critical Chain Project Management (CCPM) developed from the perspective of overall optimization based on the concept of the Theory of Constraints (TOC), which is the theory of constraints. The critical chain is a method that takes into account the dependencies that occur due to limited required resources in addition to the conventional method based on the critical path method that considers the subordinate relationships in the work process when considering the execution order of each task in a project. Project management is a practical method of project management aimed at shortening the construction period and meeting the delivery date, taking into account the human psychology and behavioral characteristics of personnel, as well as social and organizational issues, and aggregating and managing the safety margins removed from each task into a "buffer". The process management program equipped with the CCPM function preferably also has functions such as reflecting integrated information, setting the daily construction volume and the number of non-working days, and setting the CP (Critical Path). As a process management program for preferably incorporating the process data creation unit 22a into the process management device 22, a process management program without the CCPM function can also be used.

[0040] Furthermore, in this embodiment, the construction management device 10 includes a sensing data storage unit 14. The sensing data storage unit 14 preferably captures and stores, as sensing data included in the measurement information managed by the measurement management system 20, the measurement data regarding the surrounding ground, temporary structures, existing structures, etc. measured by measurement sensors when constructing, with the railway box culvert 41, which is a building annexed near the in-service track 40, as the main body structure, together with the measurement date and time, from the measurement management system 20. The sensing data (measurement data) when constructing the railway box culvert 41, which is a building, as the main body structure can be captured by the construction management device 10 via, for example, a storage medium or a wired or wireless communication network from the measurement management system 20, which is composed of measurement management devices connected wired or wirelessly to respective measurement sensors provided separately from the construction management device 10, and stored in the sensing data storage unit 14. The sensing data (measurement data) when constructing the railway box culvert 41, which is a building, as the main body structure may be stored in the sensing data storage unit 14, which is accumulated, for example, in the measurement management unit 11 connected to each measurement sensor by a known measurement management program incorporated in the construction management device 10.

[0041] When constructing the railway box culvert 41, which is a building, as the main body structure, as the measurement management system 20 for acquiring and managing preferably the sensing data (measurement data) measured by measurement sensors using IoT sensors, preferably a management system manufactured by Measurement Techno Co., Ltd. can be used.

[0042] And in the present embodiment, the design data of the three-dimensional design model 30 of the building, preferably stored in the three-dimensional design data storage unit 12, for example, created by the three-dimensional design model creation unit 21a of the three-dimensional design apparatus 21, as described above, includes data regarding the model 30a of the main body structure that models the railway casing 41 which is a building, the model 30b of the temporary construction part, the model 30c of the existing building, the model 30d of the surrounding ground, etc., as three-dimensional objects. In the design data of the models 30a, 30b, 30c of these respective buildings and the model 30d of the surrounding ground, etc., management information such as the ID number, file path, node path, etc. of each model (object) is provided. Also, in the design data of each of the sensor models 31 created as three-dimensional objects by the three-dimensional design model creation unit 21a, management information such as the ID number, file path, node path, etc. of the measuring instrument 42 is provided (see FIG. 1).

[0043] In addition, in this embodiment, preferably, the process data stored in the process data storage unit 13, for example, the process data created by the process data creation unit 22a of the process management device 22, regarding each preferably work-sectioned construction site when constructing the tunnel body 41 for railways, which is a building, as the main body structure, for example, for each of the plurality of process items 33 such as steel bar assembly, scaffold assembly, shoring assembly, formwork assembly, removal of temporary materials (scaffolds, shoring, formwork), management information such as the ID number, process name, planned start date, planned end date, etc. of the process item 33 is assigned to each type of work (see Fig. 1). Also, for each of the data regarding the plurality of process items 33 at each preferably work-sectioned construction site when constructing the tunnel body 41 for railways, which is a building, as the main body structure, when actual construction is carried out, information regarding the actual start date and time and actual end date and time, which are the actual start point and actual end point of the work, for example, can be inputted and given to the construction management device 10 by a worker as data regarding the actual start date and time of a predetermined process item 33 in the process data. Among the information regarding the actual start date and time and actual end date and time when actual construction is carried out, particularly the data regarding the actual start date and time (actual start point), by giving it to the data of each predetermined process item 33, based on the data regarding the given actual start date and time, the sensing data included in the measurement value information of each measuring instrument 42, which is managed in the measurement management system 20 by the measurement data reference unit 19 of the measurement management unit 11 described later or is sent from the measurement management system 20 and stored in the sensing data storage unit 14, can be referred to together with the measurement date and time. As a result, preferably, the sensing data by the IoT sensor included in the measurement value information can be included in the data of the on-site situation along with the progress of the time axis during the construction of the said predetermined process item 33, and it becomes possible to visualize it on the screen as time-series data that can be displayed on the time axis of the building under construction.

[0044] Furthermore, in this embodiment, 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, for example, two types of data: measured value data and management value data. The measured value data consists of measurement device information and measured 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 based on distance, depth, etc., the unit, the file path of the model layer, and the node path. The measured value information includes information such as the ID number of the measuring device 42, the measurement date and time, and the measured value (sensing data). The measured value information is information obtained by each measurement sensor at specific time intervals, for example, between several minutes and about one day. Since the measurement frequency varies depending on the measuring device 42, it is necessary to determine a representative value when cooperating with the sensor model 31. When expressing the measured value information in the construction management device 10, it is desirable to be in a state corresponding to the latest construction progress. Therefore, it is preferable to adopt the latest measured value by the measurement sensor as the representative value of the measured value information.

[0045] Also, the measured value (sensing data) is preferably output from the measurement management system 20 in CSV format. The measured value (sensing data) is 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 the attribute information based on the measurement device information.

[0046] On the other hand, the management value data indicates the threshold value of the measured value (sensing data) by the measurement sensor and can be used, for example, to issue a warning when the measured value exceeds the management value for management purposes.

[0047] In addition, the management value data includes measurement device information similar to the measurement value data and also includes management value information. The measurement device information includes, as described above, the ID number of the measurement device 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, and other information. The management value information includes the ID number of the measurement device 42, the application date, the management value, and other information. Regarding the management value, since there are changes and additions as the construction progresses, in the management value setting unit 23 described later, the value of the management value to be applied can be appropriately set or changed according to the reference date and time.

[0048] According to the present embodiment, preferably, the measurement value information such as sensing data included in the measurement value data obtained by each measurement device 42 using the IoT sensor as the measurement sensor and the management value information such as the management value included in the management value data can be associated with the sensor model 31 provided with the ID number of the same measurement device 42 via the ID number of the measurement device 42 in the measurement device information, in the three-dimensional design model 30 of the building of the site situation created by arranging the sensor model 31 at a predetermined location. Also, thereby, the measurement value information including sensing data, etc., which has been managed in the measurement management system 20 or has been imported from the measurement management system 20 and preferably stored in the sensing data storage unit 14, and the management value information including the application time point which is the reference date and time, the management value, etc., can be associated with the sensor model 31 in the three-dimensional design data of the three-dimensional design model 30 of the building of the site situation having the railway casing 41 as the main building, so that it can be reflected on the screen together with the displayed sensor model 31.

[0049] Therefore, in the present embodiment, the three-dimensional design data of the three-dimensional design model 30 of the building having the railway casing 41 as the main building is created in a state where the sensor model 31 capable of reflecting the information of the sensing data measured by each measurement sensor is arranged at a predetermined location of the three-dimensional design model 30 of the building that requires measurement by the respective measurement sensors, by being associated with the measurement device 42 using each measurement sensor (IoT sensor).

[0050] And, as described above, the construction management device 10 for a building according to this embodiment includes measurement management unit 11 that can manage the construction of a building from three-dimensional design data of a three-dimensional design model 30 of a building including a model 30b of a temporary structure, process data when constructing the building, and sensing data regarding the surrounding ground, temporary structure, or existing structure when constructing the building, which is measured by a measurement sensor. The measurement management unit 11 includes a construction association unit 15 that associates three-dimensional design data of a preferably work-sectioned predetermined construction site of the three-dimensional design model 30 of the building where a sensor model 31 is arranged 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 along the progress of the time axis of a preferably work-sectioned predetermined construction site of the three-dimensional design model 30 of the building where a sensor model 31 is arranged, a measurement data reference unit 19 that refers to sensing data by a measurement sensor along the progress of the time axis during the construction of a 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 management value setting unit 23, and a measurement value - management value comparison unit 24.

[0051] In this embodiment, the construction association unit 15 of the measurement management unit 11 preferably acquires, via a data acquisition unit 17, the design data of the three-dimensional design model 30 of the building where a sensor model 31 including a model 30b of a temporary construction part is arranged, with the model of the railway culvert 41, which is a building, as the main body structure model 30a, and preferably the process data stored in the process data storage unit 13, and incorporates and associates these to create a four-dimensional model. Also, the planned construction situation of the railway culvert 41, which is a building, can be four-dimensionally simulated and displayed, for example, on the screen of a display. That is, the construction association unit 15 can display on the screen the planned construction situation from the start to the end of the construction of the building by associating the design data and the process data of the three-dimensional design model 30 of the building where a sensor model 31 is arranged to create a four-dimensional model.

[0052] Here, the construction association unit 15 of the measurement management unit 11 includes a process / status association unit 15a and a process / model association unit 15b. In the process / status association unit 15a, as shown in FIG. 9, for each status item of the member status 32, such as "reinforcing bar", "formwork", "concrete placement", "curing", "under construction", "completed", "temporary installation", "being removed", "removed", "not started", "waiting", "not displayed after completion", "hazard treatment", "under construction - watermark", etc., for example, an operator can assign different colors 32a and edit them. The editing result is stored in the member status storage unit 18 of the measurement management unit 11. Also, in the process / status association unit 15a, for each process item 33 that constitutes the process data when constructing a preferably sectioned predetermined construction site of the building, for example, with the member status 33a during the process period and the member status 33b after the process period, different colors 32a can be further assigned and set in a color-coded state to associate these process items 33 with the member statuses 33a and 33b during and after the process period. In the process / status association unit 15a, the member status editing step S4 and the process / status association step S5 described later are performed.

[0053] In the construction model linking section 15b, as shown in FIG. 9, for each piece of data of a predetermined construction site preferably divided by work section in the three-dimensional design model 30 of a building including the model 30b of a temporary structure displayed in a hierarchical structure on the screen, one or more of the process items 33 constituting the process data of the building, which are displayed as a process table, are selected, and the data of the predetermined construction site in these three-dimensional design models 30 of the building are linked with these process items 33. The linking of the predetermined construction site of the three-dimensional design model 30 of a building including the model 30b of a temporary structure with the process item 33 can be easily performed, for example, by including a common number, symbol, etc. in the ID number of the process item 33 containing the data related to each process item 33 and the ID number of the model (object) contained in the data related to each model 30a, 30b, 30c of the building constituting the three-dimensional design model 30 of the building, the model 30d of the surrounding ground, etc., and through these ID numbers. Further, since the process item 33 is linked with the member statuses 33a, 33b during and after the process period in the process-status linking section 15a (see FIGS. 6 and 9), for each piece of data of a predetermined construction site, the member statuses 33a, 33b during and after the process period in each process item 33 can be linked. Also, the initial status before the start of construction of a predetermined construction site can be set together. As a result, with the progress of each process, it becomes possible to set, for example, by a change in color, the progress status of construction at each predetermined construction site in the three-dimensional design model 30 of the building. In the construction model linking section 15b, a construction model linking step S6, which will be described later, is to be performed.

[0054] And in this embodiment, the measurement data reference unit 19 of the measurement management unit 11, based on the data regarding the actual start date and time of a predetermined process item 33 in the process data, more specifically, for example, based on the data regarding the measurement date and time included in the measurement value information obtained by each measuring device 42, preferably refers to the sensing data managed in the measurement management system 20 at each predetermined date and time during the construction of the predetermined process item 33. Thereby, the measurement data reference unit 19 enables the on-site situation display unit 16, which will be described later, to display the sensing data referred to by the measurement data reference unit 19 included in the measurement value information, together with the management value set by the management value setting unit 23 for the process item 33, as time-series data of the on-site situation as the time axis of the construction of the predetermined process item 33 progresses, on the screen where the three-dimensional design model 30 of the building where the sensor model 31 is arranged is displayed, and to be visualized in real time or as past data. The measurement data reference unit 19 is configured to perform a measurement data reference step S8, which will be described later.

[0055] Further, in the present embodiment, the measurement management unit 11, in addition to one or two or more management values of the management value information included in the management value data by each measurement device 42 managed by the measurement management system 20, for example, associates each of a plurality of process items 33 created by the process data creation unit 22a of the process management device 22, and includes a management value setting unit 23 capable of newly setting or changing the management value for each of these process items 33. For example, corresponding to each of the process items 33, for each measurement sensor (IoT sensor) of a predetermined measurement device 42 that needs to obtain measurement data during the construction of the process item 33, the management value is reviewed, and preferably, by inputting management value data by an operator, the management value setting unit 23 is configured to reset or change the management value for each process item 33. Further, in the management value setting unit 23, data associating these process items 33 with the management values of the predetermined measurement device 42 is stored, for example, in a storage table, and at the same time as the end of each process item 33, the management value corresponding to the next process item 33 can be set to be automatically replaced. The management value setting unit 23 is configured to perform a management value setting step S7, which will be described later.

[0056] Here, the management value of the measurement data by the measurement device 42 using a predetermined measurement sensor may need to be set or changed for each process item 33 as the construction progresses. For example, as shown in FIG. 4, preferably, when the process item 33 of a predetermined construction site divided into work sections is an excavation mountain retention work, and the three-dimensional object at the predetermined construction site of the three-dimensional design model 30 of the building is a model of a crossbeam as a temporary structure 30b, the management value of the measurement data by a strain gauge attached to, for example, the first-stage crossbeam as a predetermined installation location needs to be changed for each of these more refined process items 33 at the time of excavating the ground when constructing the first-stage crossbeam and at the time of excavating the ground when constructing the second-stage or third-stage crossbeam. Therefore, for example, when an operator inputs management value data for the measurement device 42 using a predetermined measurement sensor in each process item 33 as described above, the management value setting unit

[0057] Also, for the measuring device 42 using each measuring sensor, the management value set for each predetermined process item 33 may preferably include those composed of comparison management values at multiple levels. The comparison management values at multiple levels can be, for example, six types such as "+1st-level management value", "+2nd-level management value", "+3rd-level management value", "-1st-level management value", "-2nd-level management value", and "-3rd-level management value". Preferably, the comparison management value can be, for example, 0.8 times the design management value as the 1st-level management value, the design management value itself as the 2nd-level management value, and 1.2 times the design management value as the 3rd-level management value (limit management value) with respect to the design management value.

[0058] In this embodiment, the measurement management unit 11 includes a measured value management value comparison unit 24. As described above, the measured value management value comparison unit 24 compares the sensing data by the measuring sensor along the progress of the time axis during the construction of a predetermined process item, which is referred to by the measurement data reference unit 19 based on the data regarding the actual start date and time of the predetermined process item 33 in the process data, preferably with the management value set or changed for each predetermined process item 33 by the above-described management value setting unit 23. The comparison result between the sensing data and the management value in each process item 33 compared by the measured value management value comparison unit 24 is visualized, for example, by the on-site situation display unit 16, together with the sensor model 31 capable of reflecting the information of the sensing data, on the screen of a predetermined construction site of the three-dimensional design model 30 of the building where the sensor model 31 is arranged, so that the construction of the building can be managed more appropriately. In the measured value management value comparison unit 24, a measured value management value comparison step S9 described later is performed.

[0059] The on-site status display unit 16 of the measurement management unit 11 displays the construction status from the start to the end of construction at a preferably work-sectioned predetermined construction site of the building on the screen with the 3D design model 30 of the building as a 4D model, enabling 4D simulation. Further, the on-site status display unit 16, together with the sensor model 31 capable of reflecting the information of the sensing data, visualizes the sensing data obtained by the measurement sensors referred to by the measurement data reference unit 19 in the measurement management system 20 and the sensing data storage unit 14 as data of the on-site status along with the progress of the time axis and the data of the management values (see FIGS. 3 and 4). Thereby, based on the member statuses 33a and 33b before the start of the process, during the process, and after the lapse of the process in each process item 33 set for each preferably work-sectioned predetermined construction site of the building, the on-site status display unit 16, along with the progress of the time axis according to the progress of each process item 33, can simulate and display on the screen the construction status of the 3D design model 30 of the building at a preferably work-sectioned predetermined construction site of the building, together with the sensor model 31. Also, thereby, the worker can appropriately grasp the time-dependent construction status of a predetermined construction site of the building, which is simulated and displayed in 4D on the screen by the on-site status display unit 16, along with the progress of the time axis. Further, on the screen of the predetermined construction site of the 3D design model 30 of the building where the sensor model 31 is arranged, for example, by clicking and specifying the sensor model 31, the sensing data measured by the measurement sensors preferably formed by IoT sensors that form the measurement device 42, together with the sensor model 31 capable of reflecting the information of the sensing data and referred to by the measurement data reference unit 19, is visualized as data of the on-site status along with the progress of the time axis. Therefore, while easily confirming the measurement position by the measurement device 42, it becomes possible to more appropriately grasp and manage the on-site status when constructing the railway casing 41, which is a building, as the main body structure.Furthermore, the on-site situation display unit 16 visualizes the comparison result between the sensing data and the management value compared by the measurement value management value comparison unit 24. For example, when the sensing data exceeds the set management value and when it does not, the sensing data is displayed in different colors 32a, or preferably, when the sensing data exceeds the set management value and when it does not, the color of the sensor model 31 is changed for display. Thus, as described above, it becomes possible to preferably manage the construction status of the building in real time and more appropriately.

[0060] That is, according to the present embodiment, the three-dimensional design data (four-dimensional design data) associated with the process data of the three-dimensional design model 30 of the building including the model 30b of the temporary structure with the railway box body 41 installed beside the in-use track 40 as the main body structure is linked to the measurement device 42 using each measurement sensor. A sensor model 31 capable of reflecting the information of the sensing data measured by being linked is created in a state where it is arranged at a predetermined location in a preferably work-sectioned predetermined construction site of the three-dimensional design model 30 of the building that requires measurement by the measurement sensor. Thereby, for example, by designating the sensor model 31, preferably measured by a measurement sensor of an IoT sensor and referenced by the measurement management system 20 or the sensing data storage unit 14 by the measurement data reference unit 19, the sensing data 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, together with the management value as a time-series graph, a list, etc., and it becomes possible to easily and appropriately manage the on-site situation of the construction site based on the displayed measurement data (see FIGS. 11 and 12). Also, it becomes possible to easily grasp whether the measured value exceeds the management value and to more appropriately manage the on-site situation of the construction site.

[0061] Therefore, according to the construction management device 10 of the building in this embodiment, by reflecting the daily changing site conditions, in the 4D model (a model obtained by adding the element of the time axis based on process data to the 3D model) on the screen of the construction site of the building with the culvert 41 for railways as the main body structure, it becomes possible to easily and appropriately grasp the measurement data by the measurement sensors such as IoT sensors together with the management values and manage the site conditions.

[0062] Further, according to this embodiment, preferably, the measurement data reference unit 19 directly refers to, for example, the sensing data captured from the measurement sensors into the measurement management system 20 via a wired or wireless network or the like, so that the sensing data can be displayed on the screen as real-time data of the site conditions accompanying the progress of the time axis during the construction of the predetermined process item 33. Thus, through the sensing data by the measuring device 42 using each measurement sensor, while grasping the measurement position on the screen by the sensor model 31, it becomes possible to manage the site conditions in real time while using the management values set or changed by the management value setting unit 23 according to the progress of the construction. Also, thus, for example, when the sensing data changed with the progress of the construction approaches or exceeds the management values set or changed by the management value setting unit 23 at a predetermined location of the construction site where the measuring device 42 is installed, it becomes possible to preferably issue a warning information by the warning information issuing unit 25 described later to prompt attention or interrupt the work to take countermeasures.

[0063] Furthermore, in the present embodiment, on a screen that displays a predetermined construction site of a three-dimensional design model (4D design model) 30 including a model 30b of a temporary structure associated with the process data of each process item 33, for example, a time bar can be set. As a result, along the time axis by the time bar, the on-site situation accompanying the progress of the predetermined construction site is displayed on the screen together with the transition of the sensing data based on the measurement date and time of the measured value information, and the change over time of the sensing data can be preferably visualized so as to be easily grasped on the screen while using the management value. Preferably, by specifying the date and time on the time bar, the sensing data at the specified date and time can be preferably displayed on the screen together with the management value.

[0064] Moreover, in the construction management device 10 of the present embodiment, for example, the measured value information including the sensing data of the measurement information managed by the measurement management system 20 can be taken into and stored in the sensing data storage unit 14 together with the measuring device information and the management value information. As a result, the measured value information including the sensing data can be referred to by the measurement data reference unit 19 as reproducible data together with the management value information, and can preferably be considered as reference materials when constructing a building at other similar construction sites.

[0065] In this embodiment, for example, by clicking and specifying the sensor model 31, the sensing data related to the sensor model 31, which is preferably measured by a measurement sensor using an IoT sensor and is displayed together with the management value, is referenced by the measurement data reference unit 19 and can be visualized together with the management value on the screen of the display of the construction management device 10, for example, in the form of a time-series graph or a list (see FIGS. 11 and 12). Here, the display by the time-series graph on the screen of the display of the construction management device 10 displays the sensing data of each target measurement sensor in the form of a line graph along the time axis, together with the line of the management value. The display by the list displays the measured values (sensing data) along the time axis for each measurement item. For example, when the measured value exceeds the management value, the color of the cell in the corresponding column can be gradually changed. By selecting a predetermined measured value from the list of measured values, it is also possible to transition to the sensor model 31 corresponding to the selected measured value in the model space on the screen.

[0066] In this embodiment, the sensor model 31 arranged at a predetermined construction site of the three-dimensional design model 30 of the building is preferably an icon in the form of a sensor model imitating the measuring device 42. Also 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 management value set or changed by the above-described measured value management value comparison unit 24. For example, when the sensing data exceeds the secondary management value or the tertiary management value of the comparison management value, preferably, the warning information issuing unit 25 can issue warning information in real time by gradually changing the color of the icon, which is the sensor model 31, to, for example, yellow or red, by the on-site situation display unit 16. Also, the warning information issuing unit 25 can also be configured to issue warning information by sound, such as an alarm sound, in real time when the sensing data measured by the measurement sensor exceeds, for example, the secondary management value or the tertiary management value of the comparison management value.

[0067] In this embodiment, the icon 31 is preferably displayed in an exaggerated form that is larger than the actual appearance of the measuring instrument 42 and can be easily distinguished at a glance in terms of type and installation position. The icon, which is a sensor model 31 imitating the form of the measuring instrument 42, can have its color changed by the on-site status display unit 16 according to the sensing data and management value measured by the measuring sensor associated therewith.

[0068] By these means, a worker who is an engineer can, on the screen, view the three-dimensional design model (4D design model) 30 of the building with the model 30a of the main body structure being the casing 41 for railways, taking into account the element of the time axis based on the process data, and from the sensing data which is the measured value by the measuring sensor and the tendency of its temporal change, easily grasp the on-site status of the construction site while comparing it with the management value, and appropriately make technical judgments. Also, by this means, it becomes possible to centrally manage the sensing data by various measuring sensors on the three-dimensional design model 30 of the building. Therefore, it is possible to easily share the information of the sensors regarding the installation location of the measuring instrument 42, the installed members, etc. Also, by visualizing the sensing data in conjunction with the process information, it becomes possible for the engineer to easily grasp visually the relevance between the sensing data and the on-site status of the construction site. Thus, it becomes possible to make it easier to interpret these relevances and assist in making technical judgments quickly.

[0069] And in the construction management device 10 of the building of the present embodiment having the above-described configuration, in the measurement management unit 11, for example, according to the processing procedure shown in the flowchart of FIG. 5, the construction status of a predetermined construction site, preferably divided into work sections, of the three-dimensional design model 30 of the building with the box 41 for railway as the main building model 30a can be displayed on the screen along with the sensing data measured by the measurement sensors, preferably IoT sensors, as the time axis progresses. As a result, it becomes possible to appropriately manage the construction status of the construction site by the worker who views this. In the measurement management unit 11, preferably, through the processing procedures of the data acquisition step S1, the three-dimensional design model import step S2, the process data import step S3, the member status editing step S4, the process-status association step S5, the process-model association step S6, the management value setting step S7, the measurement data reference step S8, the measurement value-management value comparison step S9, and the on-site status display step S10, the construction status of a predetermined construction site, preferably divided into work sections, of the building as the time axis progresses can be displayed on the screen along with the sensing data by the measurement sensors that can be displayed in association with the icons that are the sensor models 31. Also, in the on-site status display step S10, preferably, the attention information issuance step S10' can also be implemented.

[0070] In the three-dimensional design model import step S2, the design data of the three-dimensional design model 30 of the building with the box 41 for railway as the main building, preferably divided into work sections, created using three-dimensional CAD software and stored in the three-dimensional design data storage unit 12 is preferably acquired from the three-dimensional design data storage unit 12 by the data acquisition step S1 by the data acquisition unit 17 and imported into the measurement management unit 11. The design data of the imported three-dimensional design model 30 of the building is created in a state where the sensor model 31 capable of reflecting the information of the sensing data is arranged at a predetermined location of the three-dimensional design model 30 of the building that requires measurement by the corresponding measurement sensor by being associated with the measuring device 42 using each measurement sensor.

[0071] In the engineering data acquisition step S3, all the process items 33 of the preferably work-segmented construction sites for constructing a building with the railway culvert 41 as the main building structure, which are created using the process management software and stored in the process data storage unit 13, are acquired from the process data storage unit 13 as process data by, for example, the data acquisition step S1 by the data acquisition unit 17 and imported into the measurement management unit 11.

[0072] In the member status editing step S4, in the process / status linking section 15a of the above-mentioned construction linking section 15, as shown in FIG. 9, for each item of the member status 32, such as "rebar", "formwork", "concrete placement", "curing", "under construction", "completed", "temporary installation", "being removed", "removed", "not started", "waiting", "not displayed after completion", "hazard treatment", "under construction - watermark", "during the project period", "after the project period", "initial status before project start", etc., the operator operates while looking at the screen to set different colors 32a, and the color to be displayed according to the member status 32 when the construction status of a predetermined part of the building is displayed on the screen by the 3D design model 30 of the building is set, and these member statuses 32 are edited.

[0073] In the process / status linking step S5, in the process / status linking section 15a of the above-mentioned construction linking section 15, according to the processing procedure shown in FIG. 6, for each process item 33 constituting the process data for constructing a preferably work-segmented predetermined construction site of a building with the railway culvert 41 as the main building structure, the member status 32 is set. That is, in the process / status linking step S5, for example, the operator designates each process item 33 and sets the member status 33a during the project period (see FIG. 9) for each of these designated process items 33, and further sets the member status 33b after the project period, thereby linking these process items 33 with the member statuses 33a and 33b during and after the project period.

[0074] In the construction model association step S6, in the construction model association section 15b of the above-described construction association section 15, for each piece of design data of a selected predetermined construction site of the three-dimensional design model 30 of a building having the railway box 41 as the main building, the assignment of the construction item 33 is carried out according to the processing procedure shown in FIG. 7. That is, in the construction model association step S6, for example, the construction data composed of a plurality of construction items 33 taken into the measurement management section 11 is read, and the design data of a predetermined construction site of the three-dimensional design model 30 of a building having the railway box 41 as the main building is read. After these data are read, from the design data of the predetermined construction site of the three-dimensional design model 30 of the read building, for example, the worker selects a predetermined construction site of the building to which the construction item 33 is to be associated, performs the assignment of the construction item 33, and sets the initial member status 32 which is the initial state before the assignment process and before the construction of the corresponding construction item 33. The assignment of the construction item 33 is repeatedly carried out for all predetermined sites of the three-dimensional design models of the building.

[0075] The management value setting step S7 is preferably carried out in the above-described management value setting section 23 prior to the measurement data reference step S8. In the management value setting step S7, corresponding to each of the plurality of construction items 33 of the construction data taken in the construction data import step S3, for each measurement sensor (IoT sensor) of a predetermined measuring instrument 42 for which it is necessary to obtain measurement data during the construction of the construction item 33, preferably, the worker can newly set or change the management value by inputting the management value data.

[0076] The measurement data reference step S8 is carried out in the measurement data reference unit 19 described above. In the measurement data reference step S8, based on the data regarding the actual start date and time of a predetermined process item 33 in the process data, preferably for each predetermined date and time in a predetermined process item 33 during construction, the sensing data that is managed in the measurement management system 20 or stored in the sensing data storage unit 14 is referred to. As a result, preferably in the on-site situation display step S10 described later, the referred sensing data, together with the management value set in the management value setting step S7, is visualized in real time or as past data on the screen displaying the three-dimensional design model 30 of the building where the sensor model 31 is arranged, as the time-series data of the on-site situation accompanying the progress of the time axis of the predetermined process item 33 during construction.

[0077] The measurement value - management value comparison step S9 is carried out in the measurement value - management value comparison unit 24 described above. In the measurement value - management value comparison step S9, as shown in FIG. 8, for each process item 33 of the process data, a management value having one or more comparison management values (primary management value to n - th management value) set for each measurement sensor (IoT sensor) of a predetermined measuring instrument 42 that requires obtaining measurement data during the construction of the process item 33 is taken in. Also, one or more comparison management values of the taken - in management value are sequentially compared with the sensing data of the predetermined measuring instrument 42 measured during the construction of the process item 33 referred to in the measurement data reference step S8, for example, to determine whether each of one or more comparison management values is exceeded. When it is determined that any of the comparison management values is exceeded, through the attention information issuing step S10' of the on - site situation display step S10 described later, for example, by changing the color of the icon which is the sensor model 31, it is possible to preferably promptly issue attention - calling information in real time and prompt, for example, to take measures as required at the construction site.

[0078] The on-site situation display step S10 is to be implemented by the above-described on-site situation display unit 16. In the on-site situation display step S10, the construction status along the time axis from the start to the end of the construction associated with the process data at a preferably predetermined construction site divided into work sections of a building having a railway casing 41 as a main body structure is reproduced by a three-dimensional design model 30 of the building including a sensor model 31 capable of reflecting the information of the sensing data of the building, and can be displayed on the screen together with the visualized sensing data and management value data (see FIGS. 11 and 12).

[0079] The warning information issuing step S10' is to be implemented in the warning information issuing unit 25. For example, when the value of the sensing data exceeds the management value set in association with each process item 33, or when the sensing data approaches the set management value, the on-site situation display unit 16 can promptly issue a warning call information in real time via the sensor model 31, or promptly issue an alarm sound.
