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 for managing 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, business reforms due to the transition from two-dimensional drawings to three-dimensional models, or load application in the initial process (front) and intensive prior consideration to prevent potential setbacks in subsequent processes, enabling quality improvement and construction period shortening. For the purpose of accelerating consensus formation, improving business efficiency, enhancing quality, and ultimately improving productivity, the Ministry of Land, Infrastructure, Transport and Tourism has been formulating guidelines and attempting systematic promotion to smoothly introduce CIM (Construction Information Modeling / Management). For this reason, various three-dimensional model analysis programs and software for creating three-dimensional CIM models have been developed.

[0003] Also, mainly for architectural structures, different from conventional 3D CAD which creates two-dimensional drawings and then assembles three-dimensional shapes 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 project management software programs are known for managing the planning and execution of projects, such as in public works, to ensure that construction is completed within the specified timeframe. Additionally, a construction management system has been developed that combines 3D CAD software capable of creating BIM and CIM models with project management software, enabling easy 4D simulation at construction sites by forming a 4D model that incorporates a time axis into a 3D graphic display of the building (see, for example, Patent Document 1). The Ministry of Land, Infrastructure, Transport and Tourism is attempting to extend this function of 4D simulation over time to 3D BIM and CIM models, expanding its application to the field of civil engineering public works (see, for example, Non-Patent Document 1).

[Non-Patent Document 2] Construction and Verification of a Database Based on a Data Model of Linked Bridges and Sensors, Seiki Koyama, Nobuyoshi Yabuki, Tomohiro Fukuda: Transactions of the Japan Society of Civil Engineers, Series F3 (Civil Engineering Informatics), Vol. 77, No. 2, pp. 1_97-1_113, 2021. [Overview of the Initiative] [Problems that the invention aims to solve]

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

[0008] Preferably, the measurement sensor used here is an IoT sensor, which is a sensor that can connect to a network to collect and manage information, enabling real-time monitoring of various site conditions and the use of the collected information for predictive maintenance, predictive monitoring, data storage, and quality improvement. At construction sites for civil engineering and public works, preferably by using measurement sensors such as IoT sensors, it is possible to reduce the labor involved in various measurement tasks, and by automatically collecting measurement data (sensing data) from sensors, it is thought that the effort spent on managing and monitoring the site conditions of the building and its surroundings can be greatly reduced. On the other hand, there is a concern that construction sites will require additional effort for the management of measurement data from measurement sensors such as IoT sensors.

[0009] In other words, at construction sites, as construction progresses, site conditions change over time due to daily work, and sometimes fluctuations in measurement data due to factors unrelated to the measurement items occur, such as the movement or change of sensor installation locations due to the replacement of measurement sensors such as IoT sensors. For this reason, when engineers try to appropriately understand the site conditions and decide on countermeasures based on fluctuations in measurement data values, it becomes difficult to interpret the relationship between the site conditions that change over time and the measurement data and to make appropriate decisions on countermeasures if measurement data from measurement sensors such as IoT sensors is used alone. Furthermore, for example, in the case of measurement items where a warning is issued 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 of the measurement item as construction progresses, and this requires a great deal of effort for data organization and other tasks.

[0010] In response to this, for example, by centrally managing measurement data from various sensors on a 3D model using BIM / CIM, it is being considered that sensor information at specific locations and components of a building can be visualized, making it easy for engineers to visually grasp the relationship between sensor information and on-site conditions (see, for example, Non-Patent Literature 2). According to Non-Patent Literature 2, regarding the association between 3D models and sensor information, bridge data models and sensor data models, as well as a linked data model that connects them, have been developed. By using the developed linked data model, it is possible to manage sensor data on the 3D model in association with the data model of the bridge, which is a building.

[0011] However, according to the method of managing sensor data in association with a building data model described in Non-Patent Literature 2, the linked data model is intended for sensors installed on already completed buildings and is primarily based on the assumption that the sensors will be used for monitoring for maintenance purposes. Therefore, it does not take into account construction sites where site conditions change frequently over time during monitoring. As a result, it is difficult to reflect the daily changing site conditions and appropriately grasp measurement data from measurement sensors such as IoT sensors in a 4D model of the construction site to manage the site conditions.

[0012] The present invention aims to provide a construction management device, a construction management method, and a construction management program that enable the management of construction site conditions by easily and appropriately grasping measurement data from measurement sensors such as IoT sensors in a four-dimensional model of a construction site, reflecting the ever-changing site conditions. [Means for solving the problem]

[0013] The present invention provides a construction management device for a building that manages the construction of a building using a 3D model analysis program, and achieves the above objective by providing a construction management device that includes a display control unit that places one or more sensor models capable of identifying measurement sensors at predetermined locations where measurement by the measurement sensors is required, in a 4D model in which 3D design data of a 3D design model of a building consisting of multiple models created using a 3D CAD program and process data for constructing the building created using a process management program are associated.

[0014] Furthermore, it is preferable that the construction management device for buildings of the present invention is configured such that the sensor model is linked to measuring instruments using each measuring sensor, thereby enabling the reflection of sensing data information measured by each measuring sensor.

[0015] Furthermore, in the construction management device for buildings of the present invention, it is preferable that the sensor model is an icon that mimics the shape of a measuring instrument using each measuring sensor.

[0016] Furthermore, in the construction management device for buildings of the present invention, it is preferable that the measurement sensor is a sensor that constitutes a settlement meter, inclinometer, strain gauge, displacement meter, water level meter, distance meter, or thermometer.

[0017] Furthermore, in the construction management device for buildings of the present invention, it is preferable that the measurement sensor is an IoT sensor.

[0018] Furthermore, in the construction management device for buildings of the present invention, it is preferable that the sensing data measured by the measurement sensor is data relating to displacement, change, or load.

[0019] Furthermore, it is preferable that the construction management device for a building of the present invention includes a measurement management unit, the measurement management unit comprising a construction linking unit that associates the 3D design data of a predetermined construction area of ​​the 3D design model with a predetermined process item in the process data, and a site condition display unit that displays on a screen data of the site condition as time progresses for a predetermined construction area of ​​the 4D model on which the sensor model is placed.

[0020] Furthermore, it is preferable that the construction management device for a building according to the present invention enables the management of construction by visualizing the sensing data measured by the measurement sensor via the sensor model, which is capable of reflecting the information of the sensing data, on the screen of a predetermined construction area of ​​the four-dimensional model on which the displayed sensor model is placed.

[0021] The present invention also provides a construction management method for a building that manages the construction of a building using a 3D model analysis program. In a 4D model in which 3D design data of a 3D design model of a building composed of a plurality of models created using a 3D CAD program is associated with process data for constructing the building created using a process management program, the method includes a display control step of arranging one or more sensor models capable of identifying measurement sensors at predetermined positions where measurement by the measurement sensors is required, thereby achieving the above object.

[0022] Furthermore, the present invention provides a construction management program for a building that manages the construction of a building using a 3D model analysis program. In a 4D model in which 3D design data of a 3D design model of a building composed of a plurality of models created using a 3D CAD program is associated with process data for constructing the building created using a process management program, the program causes a computer to execute a display control step of arranging one or more sensor models capable of identifying measurement sensors at predetermined positions where measurement by the measurement sensors is required, thereby achieving the above object.

Advantages of the Invention

[Modes for carrying out the invention]

[0025] The construction management device 10 of a preferred embodiment of the present invention, shown in Figure 1, is used as a computer-based management device for appropriately understanding and managing the site conditions of a construction site, for example, in a railway undergrounding project, where a railway box structure 41 is constructed underground as a structure adjacent to an existing track 40 (see Figure 2), particularly in order to quickly confirm the impact of the construction on the existing track 40. This is achieved by installing various measuring devices 42 (see Figures 3 and 4), preferably using IoT sensors or other measuring sensors, at various locations on the construction site, and measuring items such as the displacement of temporary earth retaining, the displacement of the track construction base, the displacement of existing overhead line equipment, and the displacement of surrounding structures and ground, along with the date and time of measurement. The construction management device 10 of this embodiment manages a measurement management system 20 (see Figure 1) that centrally manages data measured by measuring instruments 42 preferably using IoT sensors installed at predetermined locations or on predetermined components at the construction site. The device references sensing data (measurement data) output, for example, in CSV format, along with the measurement date and time, or imports it into the sensing data storage unit 14 as converted data. Preferably, in a 4D model 35 that associates a 3D model using BIM / CIM with process data from a process management program, the device visualizes the sensing data along with management values, enabling real-time display and reproduction of the site conditions. The construction management device 10 of this embodiment has a function that allows for more appropriate management of measurement data (sensing data), preferably from IoT sensors, in a 4D model 35 of the construction site of a building under construction that reflects the daily changing site conditions using process data, by making it easy to grasp, for example, the location where the measurement data is taken and the scope of the process.

[0026] Furthermore, as shown in Figure 1, the construction management device 10 of this embodiment is a construction management device for managing the construction of a building using a 3D model analysis program. It includes a display control unit 28 that places one or more sensor models 31 capable of identifying measurement sensors at predetermined locations where measurement by the measurement sensors is required, in a 4D model 35 (see Figures 3 and 4) which is associated with 3D design data of a 3D design model 30 (see Figure 2) of a building, which is created using a 3D CAD program and preferably consists of multiple models including a model 30b of a temporary structure (see Figure 4), and process data for constructing the building, which is created using a process management program. Preferably, the sensor models 31 are linked to measurement instruments 42 that use each measurement sensor, so that they can reflect information of sensing data measured by each measurement sensor.

[0027] In this embodiment, the construction management device 10 preferably includes a measurement management unit 11, which includes a construction linking unit 15 that associates 3D design data of a predetermined construction area of ​​a 3D design model 30 of a building with a predetermined process item 33 in process data that requires measurement by a measurement sensor, for example, and a site condition display unit 16 that displays data on the site condition of a predetermined construction area of ​​a 4D model 35 on which a sensor model 31 is placed, as the time axis progresses. Preferably, the site condition display unit makes it possible to manage the construction of a building by visualizing the sensing data measured by the measurement sensor via the sensor model 31, which is capable of reflecting the information of the sensing data, on the screen of the predetermined construction area of ​​the 4D model 35 on which the displayed sensor model 31 is placed.

[0028] Furthermore, in this embodiment, the sensor model 31 is preferably an icon that mimics the shape of a measuring instrument 42 using each measuring sensor, and the measuring sensors are preferably IoT sensors.

[0029] Furthermore, the construction management device 10 of this embodiment preferably includes a 3D design data storage unit 12 for storing 3D design data, a process data storage unit 13 for storing process data, and a sensing data storage unit 14 for storing sensing data measured by each measurement sensor. The construction management device 10 may also further include a data acquisition unit 17 for acquiring all or any of the 3D design data, process data, and sensing data.

[0030] In this embodiment, the construction management device 10 is configured as an information processing device, including a general-purpose computer such as a personal computer. The computer includes 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, using the RAM as a work area, according to various control programs embedded in the ROM. Furthermore, the CPU, by incorporating various computer programs into ROM, enables the functioning of storage means, input means, display means, output means, etc., and also allows for the storage of various data, such as 3D design data of a 3D design model 30 of a building that includes, for example, a model 30a of the main structure of the building (see Figure 3), a model 30b of a temporary structure (see Figure 4), a model 30c of an existing structure (see Figure 3), a model 30d of the surrounding ground (see Figure 3), etc., as 3D objects, as well as data of a 4D design model 35, process data, sensing data, etc., in the database section forming the storage units 12, 13, and 14 using storage means. It also allows for the display of predetermined information on a screen such as a display using display means, and output from a printer or the like using output means.

[0031] In this embodiment, a known 3D model analysis program is incorporated into the computer-based construction management device 10. The 3D model analysis program has functions for creating 3D models, displaying point clouds, acquiring and analyzing information, etc. The 3D model analysis program can provide a development environment to the software side for implementing a measurement management unit 11, which includes various storage units 12, 13, 14, a data acquisition unit 17, a construction linking unit 15, a measurement data reference unit 19, a site condition display unit 16, a management value setting unit 23, a measurement value management value comparison unit 24, a warning information issuance unit 25, a display control unit 28, etc. As a 3D model analysis program (3D model analysis software) that can provide such a development environment to the software side, for example, PASCO's software "PADMS" can be used.

[0032] In this embodiment, the construction management device 10 preferably includes a 3D design data storage unit 12, as described above. The 3D design data storage unit 12 stores design data for a 3D design model 30 of a construction site, including a model 30a (see Figure 3) of the main structure, a model 30b (see Figure 4) of a temporary structure, a model 30c (see Figure 3) of an existing structure, a model 30d (see Figure 3) of the surrounding ground, etc., when constructing a railway box structure 41, which is a structure built adjacent to a railway track 40 in service, as the main structure. The design data for the 3D design model 30 of the construction site, including the model 30b of the temporary structure, can be created by a 3D design model creation unit 21a using a known 3D CAD program, which is incorporated into a 3D design device 21 separate from the construction management device 10. This data can then be imported into the construction management device 10, for example, via a storage medium or a wired or wireless communication network, and stored in the 3D design data storage unit 12. The design data for the 3D design model 30 of the construction site, including the temporary structure model 30b, may be created by a 3D design model creation unit using a known 3D CAD program incorporated into the construction management device 10, and then stored in the 3D design data storage unit 12.

[0033] Preferably, as the 3D CAD program (3D CAD software) for incorporating the 3D design model creation unit 21a into the 3D design apparatus 21, it is preferable to use, for example, Autodesk's "Revit," which is a BIM tool capable of creating BIM models. In the 3D design model 30 of the construction site conditions of the construction, including the temporary structure model 30b created by the 3D design model creation unit 21a, sensor models 31 (see Figures 3 and 4), preferably icons that mimic the shape of measuring instruments 42 using each measuring sensor, which can reflect the sensing data information measured by the measuring sensors, can be pre-placed as 3D objects at predetermined locations where measurement by the measuring sensors is required.

[0034] Furthermore, in this embodiment, the construction management device 10 is equipped with a process data storage unit 13, which stores process data created using a process management program for the construction of a railway box structure 41, a structure adjacent to the operational track 40, as the main structure. The process data for the construction of the railway box structure 41, which is a structure, can be created by a process data creation unit 22a using a known process management program incorporated into a separate process management device 22, and then imported 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 for the construction of the railway box structure 41, which is a structure 30, can also be created by a process data creation unit 22a using a known process management program incorporated into the construction management device 10 and stored in the process data storage unit 13.

[0035] 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 CCPM (Critical Chain Project Management) functionality, can be used. The process data created by the process data creation unit 22a includes, for example, information on the order of each process item 33 (see Figure 8) when constructing each construction area divided into work sections, as well as information on the process period consisting of the planned start date and planned end date of each process item. The process items 33 consist of items for each predetermined construction area, such as rebar assembly, scaffolding assembly, shoring assembly, formwork assembly, and removal of temporary materials (scaffolding, shoring, formwork).

[0036] Preferably, a process management program equipped with CCPM functionality is a process management software (process management program) that employs Critical Chain Project Management (CCPM), which was developed from the perspective of overall optimization based on the concept of TOC (Theory of Constraints), a theory of constraints. Critical chain is a method that, when considering the execution order of each task in a project, considers not only the dependency relationships in the work process, but also the dependency relationships that arise due to limited necessary resources. Project management is a practical method of project management that takes into account the human psychology and behavioral characteristics of personnel, as well as social and organizational problems, with the aim of shortening the construction period and adhering to deadlines, and manages the safety margin removed from each task by consolidating it into a "buffer". Preferably, a process management program equipped with CCPM functionality also has functions to reflect cost estimation information, set the daily construction volume and rest days, and set the CP (critical path). Preferably, a process management program that does not have CCPM functionality can also be used as a 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 measurement information storage unit (sensing data storage unit) 14. The sensing data storage unit 14 preferably stores measurement data from the measurement management system 20 as sensing data included in the measurement information managed by the measurement management system 20. This data pertains to the construction of a railway box structure 41, which is a structure built adjacent to a railway track 40 in service, as the main structure, measured by measurement sensors. The sensing data (measurement data) when constructing the railway box structure 41 as the main structure can be stored in the measurement management system 20, which is provided separately from the construction management device 10 and includes measurement management devices connected to each measurement sensor by wired or wireless means. This stored data can then be acquired by the construction management device 10, for example, via a storage medium or a wired or wireless communication network, and stored in the sensing data storage unit 14. When constructing the railway box structure 41, which is a building structure, as the main structure, the sensing data (measurement data) may be stored in the sensing data storage unit 14, which is stored in a measurement management unit 11 connected to each measurement sensor, for example, by a known measurement management program incorporated into the construction management device 10.

[0038] When constructing a railway box structure 41 as the main structure, a measurement management system 20 can preferably be used to acquire and manage sensing data (measurement data) measured by measurement sensors using IoT sensors, and preferably a management system manufactured by Keisoku Techno Co., Ltd. Preferably, data on displacement, change, or load of the surrounding ground, temporary structures, existing structures, etc., when constructing a structure, which is preferably measured by measurement sensors using IoT sensors, can include, for example, construction base settlement, overhead line pole settlement, bracing axial force, retaining wall horizontal displacement, rebound, on-site groundwater level, off-site groundwater level, intermediate section displacement, internal displacement of retaining wall, bracing temperature, etc. Preferably, measurement instruments 42 using IoT sensors can be used as measurement sensors for measuring this sensing data, such as a water level 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 a building, preferably stored in the 3D design data storage unit 12, is, as described above, a 3D object containing data related to the main structure model 30a, which models the railway box body 41 that is a building, a temporary structure model 30b, an existing structure model 30c, a surrounding panel model 30d, etc. Each of these design data for the structures 30a, 30b, 30c and the ground model 30d is provided with management information such as the ID number, file path, and node path of each model (object). The design data for each of the sensor models 31, which are created as 3D objects in the 3D design model storage unit 21a, is also provided with management information such as the ID number, file path, and node path of the measuring instrument 42 (see Figure 1).

[0040] Furthermore, in this embodiment, each piece of process data relating to multiple process items 33, such as rebar assembly, scaffolding assembly, support structure assembly, formwork assembly, and removal of temporary materials (scaffolding, support structure, formwork), preferably stored in the process data storage unit 13 and created by the process data creation unit 22a of the process management device 22, for each preferably divided construction area when constructing a railway box structure 41 as the main structure, is assigned management information such as the ID number of the process item 33, process name, planned start date, and planned end date for each type of work (see Figure 1). When actually performing construction, information regarding the actual start date and time and actual end date and time can be added to each piece of data relating to multiple process items 33, preferably divided construction area when constructing a railway box structure 41 as the main structure, by inputting it into the construction management device 10, for example, by a worker, as data relating to the actual start date and time of a predetermined process item 33 in the process data. By adding data related to the actual start and end dates of construction, particularly the data related to the start date, to the data of each predetermined process item 33, the measurement data reference unit 19 of the measurement management unit 11 (described later) can refer to the sensing data included along with the measurement date and time in the measurement value information of each measuring instrument 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. This makes it possible to include sensing data, preferably from IoT sensors, included in the measurement value information, in the data of the site conditions as the time axis progresses during construction of the predetermined process item 33, and to visualize it on the 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, which includes sensing data from each measuring instrument 42, 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, such as measurement data and management value data. The measurement data consists of measuring instrument information and measurement value information. The measuring instrument information includes information such as the ID number of the measuring instrument 42, the name of the measurement item, the installation location based on distance or depth, units, the file path of the model layer, and the node path. The measurement value information includes information such as the ID number of the measuring instrument 42, the measurement date and time, and the measurement value (sensing data). The measurement value information is information acquired by each measuring sensor at specific time intervals, for example, from a few minutes to about a day. Since the measurement frequency differs depending on the measuring instrument 42, it is necessary to determine a representative value when coordinating with the sensor model 31. When representing the measurement value information in the construction management device 10, it is desirable to have a state that matches the latest construction progress. Therefore, it is preferable to adopt the latest measurement value from the measuring sensor as the representative value of the measurement value information.

[0042] Furthermore, it is preferable that the measured values ​​(sensing data) are output from the measurement management system 20 in CSV format. The measured values ​​(sensing data), along with attribute information based on the measuring instrument information, are preferably referenced by the measurement data reference unit 19 or stored in the measurement management system 20 or the sensing data storage unit 14.

[0043] On the other hand, control value data indicates the threshold values ​​(sensing data) measured by measurement sensors, and can be used for management purposes, such as issuing a warning when the measured value exceeds the control value.

[0044] Furthermore, the control value data includes measurement equipment information similar to that of the measurement data, as well as control value information. The measurement equipment information includes, as described above, the ID number of the measurement equipment 42, the name of the measurement item, the installation location based on distance, depth, etc., units, the file path of the model layer, the node path, etc. The control value information includes the ID number of the measurement equipment 42, the application date, the control value, etc. Since the control values ​​may change or be added as construction progresses, the control value setting unit 23, described later, can appropriately set or change the values ​​of the applicable control values ​​according to the reference date and time.

[0045] According to this embodiment, measurement value information such as sensing data and management value information such as management values ​​included in the measurement data from each measuring instrument 42, which preferably uses an IoT sensor as a measuring sensor, can be linked to the sensor model 31 in the 3D design model 30 or 4D model 35 of the construction site, which is created by placing sensor models 31 with the same ID number as the measuring instrument 42 in predetermined locations, via the ID number of the measuring instrument 42 in the measuring instrument information. Furthermore, this makes it possible to associate measurement value information, including sensing data, which is managed in the measurement management system 20 or taken in from the measurement management system 20 and preferably stored in the sensing data storage unit 14, with the sensor model 31 in the data of the 3D design model 30 or 4D model 35 of the construction site, which preferably uses a railway box body 41 as the main structure, with the sensor model 31, and reflect it on the screen together with the displayed sensor model 31.

[0046] Therefore, in this embodiment, the data for the 4D model 35 of a building whose main structure is a railway box 41 is linked to measuring instruments 42 using each measuring sensor (IoT sensor). A sensor model 31 that can reflect the sensing data information measured by each measuring sensor is created by the display control unit 28, which will be described later, in a state where it is placed at a predetermined location on the 4D model 35 where measurement by the measuring sensor is required.

[0047] Furthermore, the construction management device 10 of this embodiment preferably includes a measurement management unit 11 that enables the management of construction work based on three-dimensional design data of a three-dimensional design model 30 of the building, process data for construction work, and sensing data related to the surrounding ground, temporary structures, or existing structures measured by a measurement sensor during construction work. The measurement management unit 11 preferably includes a construction linking unit 15 that associates three-dimensional design data of predetermined construction sections divided into work areas in a three-dimensional design model 30 of the building, on which a sensor model 31 is preferably placed, with predetermined process items 33 in the process data, and a site condition display unit 16 that displays data on the site conditions as the time axis progresses for predetermined construction sections divided into work areas in a four-dimensional model 35, on which a sensor model 31 is preferably placed. Preferably, the construction management device 10 may further include a measurement data reference unit 19 that references sensing data from measurement sensors as the time axis progresses during construction of a predetermined process item 33 based on data relating to the actual start date and time of a predetermined process item 33 in the process data, a management value setting unit 23, and a measurement value management value comparison unit 24.

[0048] In this embodiment, the construction linking unit 15 of the measurement management unit 11 preferably acquires design data of a 3D design model 30 of a building where a sensor model 31 is placed, preferably stored in the 3D design data storage unit 12, which includes a model 30a of the main structure, a model 30b of the temporary structure, and preferably stored in the process data storage unit 13, preferably via the data acquisition unit 17, and associates these to create a 4D model 35. This makes it possible to simulate the planned construction status of the railway box structure 41, which is a building, in 4D and display it on the screen of a display, for example, via the site status display unit 16. In other words, the construction linking unit 15 creates a 4D model 35 by associating the design data of the 3D design model 30 of the building where the sensor model 31 is placed with the process data, making it possible to display the planned construction status of the building from the start to the end of construction on the screen.

[0049] Here, 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. In the process / status linking unit 15a, as shown in Figure 8, each status item of the member status 32, such as "rebar", "formwork", "concrete pouring", "curing", "in construction", "completed", "temporary", "removing", "removed", "not started", "waiting", "hidden after completion", "surface preparation", "in construction - transparent", etc., can be edited by assigning different colors 32a to each worker. The editing results are stored in the member status storage unit 18 of the measurement management unit 11. Furthermore, the process / status linking unit 15a can also set up a color-coded system where, for example, different colors 32a are assigned to each process item 33 that constitutes the process data when constructing a predetermined construction area preferably divided into work sections of a building, for example, the member status 33a during the process period and the member status 33b after the process period has elapsed, and link these process items 33 with the member statuses 33a and 33b during and after the process period. The process / status linking unit 15a is configured to perform the member status editing step S4 and the process / status linking step S5, which will be described later.

[0050] In the process / model linking unit 15b, as shown in Figure 9, for each data of a predetermined construction area, preferably divided into work sections, of the 3D design model 30 of the building, including the temporary structure model 30b, which is displayed in a hierarchical structure on the screen, one or more process items 33 that constitute the construction process data of the building are selected and linked with the data of the predetermined construction area in the 3D design model 30 of the building. This linking of predetermined construction areas in the 3D design model 30 of the building, including the temporary structure model 30b, and the process items 33 can be easily done by including a common number or symbol in the ID number of the process item 33 containing the data for each process item 33 and the ID number of the model (object) included in the data for each structure model 30a, 30b, 30c, the surrounding ground model 30d, the sensor model 31, etc. that constitute the 3D design model 30 of the building, and using these ID numbers. Furthermore, since process item 33 is linked to the member status 33a and 33b during and after the process period in the process / status linking unit 15a (see Figures 6 and 8), the member status 33a and 33b during and after the process period can be linked for each data of a predetermined construction area in each process item 33. In addition, the initial status of a predetermined construction area before the start of the process can also be set. As a result, the progress of construction at each predetermined construction area of ​​the 3D design model 30 of the building can be set, for example, by a change in color, as each process progresses. The process / model linking unit 15b performs the 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 in the measurement management system 20, preferably at predetermined times during the construction of the predetermined process item 33, based on data relating to the start date and time (start time of actual performance) of a predetermined process item 33 in the process data, more specifically, based on data relating to the measurement date and time included in the measurement value information from each measuring instrument 42. As a result, the measurement data reference unit 19 is equipped with a function that allows the sensing data referenced by the measurement data reference unit 19 included in the measurement value information to be visualized in real time or as historical data on a screen displaying a 4D model 35 in which the sensor model 31 is arranged, together with the management value for the process item 33 set in the management value setting unit 23, as time-series data of the site conditions as the time axis progresses during the construction of the predetermined process item 33 (see Figures 4, 10 to 12). The measurement data reference unit 19 performs the measurement data reference step S8, which will be described later.

[0052] Furthermore, in this embodiment, the measurement management unit 11 preferably includes a management value setting unit 23 that can set or change management values ​​for each of a plurality of process items 33 created by the process data creation unit 22a of the process management device 22, in addition to one or more management values ​​of the management value information included in the management value data from each measuring instrument 42 managed by the measurement management system 20. For example, the management value is reviewed for each measurement sensor (IoT sensor) of a predetermined measuring instrument 42 that is required to obtain measurement data during the construction of each process item 33, corresponding to each process item 33, and preferably, the management value data is input by a worker, so that the management value setting unit 23 can reset or change the management value for each process item 33. The management value setting unit 23 performs the management value setting step S7, which will be described later.

[0053] Here, the management values ​​of the measured values ​​(sensing data) from the measuring instrument 42 using a predetermined measuring sensor may need to be set or changed for each process item 33 as the construction progresses. For example, as shown in Figure 4, if the process item 33 of a preferably divided predetermined construction area is excavation and retaining wall work, and the 3D object in the predetermined construction area of ​​the 4D model 35 is a model of bracing as a temporary structure 30b, then the management values ​​of the measured data from a strain gauge attached to, for example, the first bracing as a predetermined installation location need to be changed for each of these more subdivided process items 33, during the excavation of the ground when constructing the first bracing and during the excavation of the ground when constructing the second and third bracing. For this reason, in this embodiment, for example, a worker inputs management value data for the measuring instrument 42 using a predetermined measuring sensor in each process item 33, as described above, and the management value setting unit 23 sets or changes for each of these more subdivided process items 33.

[0054] Furthermore, for each measuring instrument 42 using a measurement sensor, the control values ​​set for each predetermined process item 33 may preferably include comparative control values ​​of multiple levels. For example, six types of comparative control values ​​can be used, such as "+1st-level control value", "+2nd-level control value", "+3rd-level control value", "-1st-level control value", "-2nd-level control value", and "-3rd-level control value". Preferably, the comparative control values ​​can be set such that, for example, the design control value × 0.8 is the 1st-level control value, the design control value itself is the 2nd-level control value, and the design control value × 1.2 is the 3rd-level control value (limit control value) relative to the design control value. The comparative control values ​​can, for example, the 1st-level control value can be set as a caution value that does not require immediate action, preferably prompting action to be taken in advance. For example, the 2nd-level control value can be set as an acceptable value relative to the set value, preferably prompting action to be taken immediately. For example, the 3rd-level control value can be set as an NG value that exceeds the acceptable value, preferably prompting work to be stopped.

[0055] In this embodiment, the measurement management unit 11 includes a measurement value management value comparison unit 24. As described above, the measurement value management value comparison unit 24 compares sensing data from measurement sensors, which are referenced by the measurement data reference unit 19 based on data relating to the actual start date and time of a predetermined process item 33 in the process data, with a management value preferably set or changed for each predetermined process item 33 in the management value setting unit 23. The comparison result between the sensing data for each process item 33 compared by the measurement value management value comparison unit 24 and the management value is visualized, for example, by the site situation display unit 16 on the screen of a predetermined construction area of ​​the 4D model 35 on which the sensor model 31 is placed, along with the sensor model 31 that can reflect the sensing data information, thereby enabling more appropriate management of the construction of the building. The measurement value management value comparison unit 24 performs the measurement value management value comparison step S9, which will be described later.

[0056] In this embodiment, the construction management device 10 includes a display control unit 28 that places one or more sensor models 31, which can identify measurement sensors, at predetermined positions where measurement by the measurement sensors is required in a four-dimensional model 35 in which three-dimensional design data and process data are associated. The display control unit 28 can preferably be provided in the measurement management unit 11. The display control unit 28 can, for example, control the display so that the sensor models 31 are displayed on the screen of the four-dimensional model 35 in which a three-dimensional design model 30 of a building created by the three-dimensional design model creation unit 21a of the three-dimensional design device 21 is associated with process data and preferably includes sensor models 31 represented by icons (see Figures 3 and 4). The display control unit 28 can also control the display so that the sensor models 31 placed in the four-dimensional model 35 of the building's site conditions are displayed on the screen in a different position. The display control unit 28 can also control the display so that necessary sensor models 31 are newly added and displayed in the four-dimensional model 35 of the building's site conditions.

[0057] The site status display unit 16, located in the measurement management unit 11, can display the construction status from the start to the end of construction in a predetermined construction area, preferably divided into work sections, on the screen as a four-dimensional model 35 of the building, enabling four-dimensional simulation. The site status display unit 16 also has a function to visualize sensing data from measurement sensors referenced by the measurement management system 20 and the sensing data storage unit 14 via the measurement data reference unit 19, along with a sensor model 31 that can reflect sensing data information, as data on the site status as it progresses along the time axis (see Figures 3 and 4). As a result, based on the member status 33a and 33b before the start of the process, during the process, and after the process period has elapsed for each process item 33 set for each predetermined construction area, preferably divided into work sections of the building, the site status display unit 16 can display a four-dimensional simulation on the screen, along with the sensor model 31, the construction status of the three-dimensional design model 30 of the building in a predetermined construction area, preferably divided into work sections, as it progresses along the time axis due to the progress of each process item 33. Furthermore, this enables workers to appropriately grasp the time-series construction status of a predetermined construction area of ​​a building, as it progresses along the time axis, as displayed on the screen in a 4D simulation by the site situation display unit 16. Additionally, by clicking on the sensor model 31 on the screen of a predetermined construction area of ​​the 4D model 35 where the sensor model 31 is located, workers can visualize the sensing data, which is measured by a measurement sensor (preferably an IoT sensor) forming the measuring instrument 42 and referenced by the measurement data reference unit 19, along with the sensor model 31 which can reflect the information of the sensing data, as site situation data as it progresses along the time axis. This allows workers to easily confirm the measurement position by the measuring instrument 42 and to more appropriately grasp and manage the site conditions when constructing the railway box structure 41 as the main structure.Furthermore, the site status display unit 16 visualizes the comparison results between the sensing data and the control value compared by the measurement value control value comparison unit 24. For example, it displays the sensing data in different colors 32a depending on whether the sensing data exceeds or does not exceed the set control value, or preferably changes the color of the sensor model 31 depending on whether the sensing data exceeds or does not exceed the set control value. This makes it possible to manage the construction status of the building more appropriately, preferably in real time, as described above.

[0058] In other words, according to this embodiment, a 3D design model 30 of a construction structure, including a model 30b of a temporary structure whose main structure is a railway box 41 installed adjacent to the operational track 40, is linked to process data. The data of the 4D model 35 is created with sensor models 31 that are linked to measuring instruments 42 using each measuring sensor and capable of reflecting sensing data information, and are placed at predetermined locations in the 4D model 35, preferably in predetermined construction areas divided into work sections, where measurement by the measuring sensors is required. As a result, for example, by specifying the sensor model 31, sensing data measured by measuring sensors, preferably IoT sensors, and referenced by the measurement data reference unit 19 in the measurement management system 20 and sensing data storage unit 14, can be displayed together with the sensor model 31 on the screen of the construction management device 10 as a timeline chart, list, etc., along with management values, in a state where the measurement location can be easily grasped. This makes it possible to easily and appropriately manage the site conditions of the construction site based on the displayed measurement data (see Figures 10 to 12). Furthermore, it becomes easier to determine whether the measured values ​​exceed the control limits, enabling more appropriate management of the construction site conditions.

[0059] Therefore, according to the construction management device 10 of this embodiment, it becomes possible to easily and appropriately grasp measurement data from measurement sensors such as IoT sensors, preferably together with management values, in a 4D model 35 on the screen of a construction site of a building whose main structure is a railway box 41, in order to reflect the site conditions that change day by day, and to manage the site conditions.

[0060] Furthermore, according to this embodiment, preferably the measurement data reference unit 19 directly references the sensing data acquired from, for example, the measurement sensor to the measurement management system 20, thereby enabling the display of the sensing data on the screen as real-time data of the site conditions as the time axis progresses during the construction of the predetermined process item 33. This makes it possible to manage the site conditions in real time, using management values ​​set or changed by the management value setting unit 23 according to the progress of construction, while grasping the measurement position on the screen via the sensing data from the measuring instrument 42 using each measurement sensor using the sensor model 31. In addition, this makes it possible to issue warning information by the warning information issuing unit 25, preferably described later, when the sensing data that has changed with the progress of construction exceeds the management value at a predetermined location on the construction site where the measuring instrument 42 is installed, thereby prompting caution or interrupting work to take countermeasures.

[0061] Furthermore, in this embodiment, a time bar can be set on the screen displaying a predetermined construction area of ​​the four-dimensional model 35, which includes a model 30b of a temporary structure linked to the process data of each process item 33 (see Figures 4, 10, and 11). This makes it possible to display the site conditions as the progress of a predetermined construction area progresses along the time axis of the time bar, along with the changes in sensing data based on the measurement date and time of the measurement information, making it possible to visualize the changes in sensing data over time in an easy-to-understand manner on the screen, preferably using control values. Preferably, by specifying the date and time in the time bar, it becomes possible to display the sensing data at the set date and time, preferably together with control values, on the screen.

[0062] Furthermore, in the construction management device 10 of this embodiment, measurement value information, including sensing data of measurement information managed by, for example, the measurement management system 20, can be acquired and stored in the sensing data storage unit 14 together with measurement equipment information and management value information. As a result, the measurement value information, including sensing data, together with the management value information, can be referenced by the measurement data reference unit 19 as reproducible data and preferably used as reference material when constructing buildings at other similar construction sites.

[0063] Furthermore, in this embodiment, by clicking to specify, for example, a sensor model 31, the sensing data measured by a measurement sensor, preferably an IoT sensor, related to that sensor model 31, which is displayed together with the management value, is referenced by the measurement data reference unit 19 and can be visualized on the screen of the construction management device 10's display, for example, as a time-series chart or a list, together with the management value (see Figures 10 to 12). Here, the time-series chart display on the screen of the construction management device 10's display shows 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 list display shows the measured value (sensing data) along the time axis for each measurement item, and for example, if the measured value exceeds the management value, the color of the cell in the corresponding column can be changed in stages. By selecting, for example, a predetermined measured value whose color has changed from the list of measured values, the screen can be transitioned to a screen that displays the models around the sensor model 31 corresponding to the selected measured value in the model space on the screen.

[0064] In this embodiment, the sensor model 31 placed at a predetermined construction site in the 3D design model 30 of the building is preferably an icon, and preferably the measurement management unit 11 further comprises a warning information issuing unit 25. The warning information issuing unit 25 is configured to issue warning information in real time when the sensing data measured by the measurement sensor is compared with a management value set or changed by the measurement value management value comparison unit 24, for example, and exceeds a secondary or tertiary management value of the comparison management value, preferably by displaying the icon, which is the sensor model 31, in stages, for example, yellow or red, via the site situation display unit 16. Furthermore, the warning information issuing unit 25 can also issue warning information in real time by sound, such as an alarm sound, when the sensing data measured by the measurement sensor exceeds a secondary or tertiary management value of the comparison management value, for example.

[0065] In this embodiment, the icon 31 is preferably displayed in an exaggerated form, larger than the actual external shape of the measuring instrument 42, so that its type and installation location can be easily identified. The icon, which is a sensor model 31 that mimics the shape of the measuring instrument 42, can have its color changed by the field situation display unit 16 according to the sensing data and management value measured by the measurement sensor associated with it.

[0066] These features enable engineers and workers to easily grasp the site conditions at the construction site by comparing them with control values, based on a 4D model 35 of the building, with the railway box 41 as the main structure model 30a, which incorporates the time axis element from process data displayed on the screen, as well as sensing data from measurement sensors and its temporal changes, thereby enabling them to make appropriate technical decisions. Furthermore, this allows for centralized management of sensing data from various measurement sensors on the 4D model 35 of the building, making it easy to share sensor information regarding the installation locations of measurement equipment 42 and installed components. Additionally, by visualizing the sensing data in conjunction with process information, engineers can easily and visually grasp the relationship between the sensing data and the site conditions at the construction site, making it easier to interpret these relationships and assisting in making quick technical decisions.

[0067] Furthermore, in the construction management device 10 of this embodiment, which has the above-described configuration, the measurement management unit 11 can, for example, follow the processing procedure shown in the flowchart of Figure 5 to display on the screen the construction status of a predetermined construction area, preferably divided into work sections, of a four-dimensional model 35 of a building, where the railway box 41 is the main structure model 30a, along with sensing data measured by measurement sensors, preferably IoT sensors, as time progresses. This makes it possible for workers to appropriately manage the construction status at the construction site by viewing this information. The measurement management unit 11 preferably performs a processing procedure consisting of a data acquisition step S1, a 3D design model import step S2, a process data import step S3, a member status editing step S4, a process / status linking step S5, a process / model linking step S6, a management value setting step S7, a measurement data reference step S8, a measurement value / management value comparison step S9, and a site status display step S10, which allows the construction status of a predetermined construction area, preferably divided into work sections, as time progresses, to be displayed on the screen along with sensing data from a measurement sensor that can be displayed in association with an icon, which is a sensor model 31. In addition, a display control step S11 is performed in the site status display step S10, and preferably a warning information issuance step S12 can also be performed.

[0068] In the 3D design model import step S2, the design data of the 3D design model 30 of a construction structure, preferably a construction section divided into work areas, which is a railway box structure 41 and is stored in the 3D design data storage unit 12 and created using 3D CAD software, is preferably acquired from the 3D 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 3D design model 30 of the construction structure is preferably created with a sensor model 31 that can reflect sensing data information by linking it to measuring instruments 42 using each measuring sensor, and is placed at a predetermined location on the 3D design model 30 of the construction structure that requires measurement by the measuring sensor.

[0069] In the process data acquisition step S3, all process items 33 for preferably divided construction sections, which are stored in the process data storage unit 13 and created using process management software, for constructing a railway box structure 41 as the main structure, 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 Figure 8, the worker can operate the screen while looking at the screen to assign different colors 32a to each component status 32, such as "rebar", "formwork", "concrete pouring", "curing", "under construction", "completed", "temporary", "under removal", "removed", "not started", "waiting", "hidden after completion", "surface preparation", "under construction - transparent", "during the process", "after the process period has elapsed", and "initial status before the process starts", thereby setting the colors that will be displayed on the screen according to the component status 32 when the construction status of a given part of the building is displayed on the screen using the 4D model 35, and editing these component statuses 32.

[0071] In the process / status linking step S5, the process / status linking unit 15a of the construction linking unit 15 described above sets a member status 32 for each process item 33 that constitutes the process data when constructing a predetermined construction area, preferably divided into work sections, of a building whose main structure is a railway box body 41, in accordance with the processing procedure shown in Figure 6. That is, in the process / status linking step S5, for example, a worker specifies each process item 33 and sets a member status 33a during the process period for each of these specified process items 33 (see Figure 8), and further sets a member status 33b after the process period has elapsed, thereby linking these process items 33 with the member statuses 33a and 33b during and after the process period.

[0072] In the process-model linking step S6, the process-model linking unit 15b of the construction linking unit 15, following the processing procedure shown in Figure 7, assigns process items 33 to each of the selected predetermined construction area design data of the 3D design model 30 of the building whose main structure is a railway box 41, thereby creating a 4D design model 35. That is, in the process-model linking step S6, for example, process data consisting of multiple process items 33 imported into the measurement management unit 11 is read, and design data of predetermined construction areas of the 3D design model 30 of the building whose main structure is a railway box 41 is read. After reading this data, for example, a worker selects a predetermined construction area of ​​the building to which they want to link process items 33 from the design data of the predetermined construction area of ​​the read 3D design model 30 of the building, assigns the process items 33, and sets the initial member status 32, which is the initial state before the assigned process, before construction of the corresponding process item 33. The assignment of process item 33 will be repeatedly carried out for all designated parts of the 3D design model of the building.

[0073] The control value setting step S7 is performed in the control value setting unit 23 described above. In the control value setting step S7, for example, a control value is newly set or changed in association with each of the multiple process items 33 created by the process data creation unit 22a of the process control device 22, and the control value relating to the sensing data measured by one or more measuring sensors in the said process item 33 is set.

[0074] The measurement data reference step S8 is performed in the measurement data reference unit 19 described above. In the measurement data reference step S8, based on data relating to the actual start date and time of a predetermined process item 33 in the process data, sensing data managed in the measurement management system 20 or stored in the sensing data storage unit 14 is referenced, preferably for each predetermined date and time in the predetermined process item 33 during construction. This makes it possible to visualize the referenced sensing data in real time or as historical data on a screen displaying a 3D design model 30 of the building where the sensor model 31 is placed, along with the management value set in the management value setting step S7, as time-series data of the site conditions as the predetermined process item 33 progresses along the time axis during construction.

[0075] The measurement value management value comparison step S9 is performed by the measurement value management value comparison unit 24 described above. In the measurement value management value comparison step S9, management values, which have one or more comparison management values, are acquired for each process item 33 of the process data, for each measurement sensor (IoT sensor) of a predetermined measuring instrument 42, for which measurement data is required during the construction of the process item 33. The acquired management values, one or more comparison management values, are sequentially compared with the sensing data from the predetermined measuring instrument 42 measured during the construction of the process item 33, which was referenced in the measurement data reference step S8, to determine, for example, whether each of the one or more comparison management values ​​is exceeded. If it is determined that any of the comparison management values ​​has been exceeded, preferably, via the warning information issuance step S12 of the site status display step S10 described later, warning information is preferably issued in real time as appropriate and promptly, for example, by changing the color of the icon, which is the sensor model 31, to prompt, for example, taking countermeasures or stopping work as necessary at the construction site.

[0076] The site status display step S10 is performed by the site status display unit 16 described above. In the site status display step S10, the construction status of a building whose main structure is a railway box 41, preferably in a predetermined construction area divided into work sections, is reproduced by a four-dimensional model 35 including a sensor model 31 that can reflect information from the building's sensing data, along with the visualized sensing data and management value data, as the construction progresses along the time axis from the start to the end of construction, which is associated with process data. This can then be displayed on the screen (see Figures 10 to 12).

[0077] The display control step S11 is performed by the display control unit 28 described above. In the display control step S11, one or more sensor models 31 that can identify measurement sensors are placed in a 4D model 35, which associates 3D design data and process data, at predetermined locations where measurement by the measurement sensors is required (see Figures 10 to 12).

[0078] The warning information issuance step S12 is performed by the warning information issuance unit 25. For example, when the value of the sensing data exceeds a control value set in association with each process item 33, or when the sensing data approaches a set control value, the field status display unit 16 can quickly issue warning information in real time via the sensor model 31 or quickly issue an alarm sound.

[0079] Therefore, the construction management method for managing the construction of a building using the 3D model analysis program of this embodiment includes a display control step S11 in which one or more sensor models 31 capable of identifying measurement sensors are placed at predetermined positions where measurement by the measurement sensors is required, in a 4D model 35 which associates 3D design data of a 3D design model 30 of a building consisting of multiple models created using a 3D CAD program with process data for constructing the building created using a process management program.

[0080] Furthermore, the construction management device 10 of this embodiment is a construction management program for a building that manages the construction of a building using a 3D model analysis program. It manages the construction of a building by having a computer execute a display control step in which one or more sensor models 31 capable of identifying measurement sensors are placed at predetermined locations where measurement by the measurement sensors is required, in a 4D model 35 in which 3D design data of a 3D design model 30 of a building consisting of multiple models created using a 3D CAD program and process data for when the building is constructed, created using a process management program.

[0081] It should be noted that the present invention is not limited to the above embodiments and can be modified in various ways. For example, the measurement sensor does not necessarily have to be an IoT sensor, but may be any other known sensor that constitutes various measuring instruments.
