Description

Article 30, paragraph 2 of the Patent Act applies. ・Proceedings of the 46th Civil Engineering Informatics Symposium (Published September 17, 2021, by the Civil Engineering Informatics Committee of the Japan Society of Civil Engineers) ・Lectures of the 46th Civil Engineering Informatics Symposium (Held online on September 27, 2021, hosted by the Civil Engineering Informatics Committee of the Japan Society of Civil Engineers)

The present invention relates to a construction management device, a construction management method, and a construction management program for managing construction work using a three-dimensional model analysis program.

In recent years, in the field of civil engineering and public works such as bridges, tunnels, dams, earthworks, and rivers, the Ministry of Land, Infrastructure, Transport and Tourism has been formulating guidelines and systematically promoting the smooth introduction of CIM (Construction Information Modeling/Management) with the aim of speeding up consensus building, streamlining operations, improving quality, and ultimately increasing productivity through front-loading, which involves transforming operations by transitioning from 2D drawings to 3D models when constructing various structures, or by placing a strain on early processes (the front) to allow for intensive advance consideration and preventing potential rework in later processes, thereby improving quality and shortening construction time. To this end, various 3D model analysis programs and software for creating 3D CIM models have been developed.

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

Furthermore, various process management software programs are known for managing the planning and implementation of public works projects, for example, to ensure that construction is completed within the set construction period. Construction management systems have also been developed that combine 3D CAD software capable of creating BIM and CIM models with process management software, enabling easy 4D simulation, for example, at construction sites, by creating a 4D model that incorporates time-based elements into the 3D graphic display of a building (see, for example, Patent Document 1). The Ministry of Land, Infrastructure, Transport and Tourism is attempting to apply this 4D modeling function, which simulates 4D progress over time, to 3D BIM and CIM models, in an effort to expand the scope of civil engineering public works projects (see, for example, Non-Patent Document 1).

Guide to using 4D models for the purpose of information sharing between design and construction (draft), March 2021, published by the Ministry of Land, Infrastructure, Transport and Tourism Construction and Verification of a Database Based on a Bridge and Sensor Collaboration Data Model, S. Koyama, N. Yabuki, and T. Fukuda: Journal of the Japan Society of Civil Engineers, Proceedings of the 3rd Annual Meeting of the Japan Society of Civil Engineers (JSCE), Vol. 77, No. 2, pp. 1_97-1_113, 2021.

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

Here, IoT sensors, which are preferably used as measurement sensors, are sensors that can connect to a network to collect and manage information, making it possible to monitor various on-site conditions in real time and utilize the collected information for predictive maintenance, early warning monitoring, data accumulation, quality improvement, and more. Even at construction sites for public civil engineering works and other buildings, the use of measurement sensors, such as IoT sensors, will enable labor savings in various measurement tasks, and the automatic collection of sensor-based measurement data (sensing data) is expected to significantly reduce the labor required to manage and monitor the construction site and its surrounding conditions. However, at construction sites, there are concerns that managing measurement data from measurement sensors, such as IoT sensors, will require additional labor.

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

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

However, according to the method of managing sensor data by associating it with a building data model described in Non-Patent Document 2, the linked data model targets sensors installed in already completed buildings and is intended to be used primarily for monitoring for maintenance and management. Therefore, it is not designed for building construction sites, where on-site conditions change frequently over time during monitoring. Therefore, it is difficult to reflect the daily changing on-site conditions and appropriately grasp measurement data from measurement sensors such as IoT sensors, along with management values, in a 4D model of the building construction site to manage the on-site conditions.

The present invention aims to provide a construction management device, a construction management method, and a construction management program that reflect the daily changing site conditions and enable the management of site conditions by easily and appropriately grasping measurement data from measurement sensors such as IoT sensors along with management values in a four-dimensional model of the construction site.

The present invention is a construction management device for managing construction of a building using a 3D model analysis program, and is equipped with a measurement management unit that can manage the construction of a building based on 3D design data of a 3D design model of the building created using a 3D CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors regarding the surrounding ground, temporary structures, or existing structures when constructing the building. The 3D design data of the 3D design model of the building is created by linking sensor models that are linked to measuring equipment using each measurement sensor and can reflect information from the sensing data measured by each measurement sensor, and placing sensor models at predetermined locations on the 3D design model that require measurement by the measurement sensors. The measurement management unit includes a construction linking unit that links the 3D design data of a predetermined construction portion of the 3D design model in which the sensor model is placed with a predetermined process item in the process data, and a construction linking unit that links the sensor models with the construction data. The above-mentioned objectives have been achieved by providing a construction management device for building construction, which is capable of managing construction work by visualizing the results of a comparison between the sensing data compared by the measurement value control value comparison unit and the control value, along with the sensor model that can reflect sensing data information, on a screen of the specified construction site of the 3D design model in which the displayed sensor model is placed, and a site status display unit that displays on a screen the site status data as the time axis progresses for a specified construction site of the 3D design model in which the model is placed, as the time axis progresses. The measurement management unit further includes a measurement data reference unit and a measurement value control value comparison unit. The measurement value control value comparison unit compares sensing data from the measurement sensor as the time axis progresses during construction of the specified process item, as referenced by the measurement data reference unit based on data relating to the start time of the performance of the specified process item in the process data, with a control value set for each specified process item.

Furthermore, it is preferable that the construction management device for a building of the present invention includes a control value set for each of the specified process items that consists of multiple levels of comparative control values.

Furthermore, it is preferable that the construction management device for a building of the present invention issues warning information when the measurement value control value comparison unit determines that the sensing data from the measurement sensor exceeds one of the multiple comparison control values, making it possible to change subsequent on-site responses at each stage.

Furthermore, it is preferable that the construction management device for a building of the present invention is configured so that the site status display unit can visualize the comparison results in different colors depending on whether the sensing data exceeds the set management value or not.

Furthermore, it is preferable that the construction management device for a building of the present invention is configured to visualize the comparison results by changing the color of the sensor model depending on whether the sensing data exceeds or does not exceed the set management value.

Furthermore, in the construction management device for a building of the present invention, it is preferable that the sensing data referenced by the measurement data reference unit is data in a measurement management system.

Furthermore, in the construction management device for a building of the present invention, it is preferable that the sensor model is an icon that resembles the shape of the measuring equipment that uses each of the measurement sensors.

Furthermore, in the construction management device for a building of the present invention, it is preferable that the measurement sensor is a sensor constituting a subsidence gauge, inclinometer, strain gauge, displacement gauge, water level gauge, distance meter, or thermometer.

Furthermore, in the construction management device for a building of the present invention, it is preferable that the measurement sensor is an IoT sensor.

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

The present invention also provides a construction management method for managing construction of a building using a three-dimensional model analysis program, and includes a measurement management step that enables management of construction of the building based on three-dimensional design data of a three-dimensional design model of the building created using a three-dimensional CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors relating to the surrounding ground, temporary structures, or existing structures when constructing the building. The three-dimensional design data of the three-dimensional design model of the building is created in a state in which sensor models that are linked to measuring equipment using each measurement sensor and can reflect information on sensing data measured by each measurement sensor are placed at predetermined locations on the three-dimensional design model that require measurement by the measurement sensors. The measurement management step includes a construction linking step that associates design data of a predetermined construction portion of the three-dimensional design model in which the sensor model is placed with a predetermined process item in the process data, and a construction linking step that associates the design data of a predetermined construction portion of the three-dimensional design model in which the sensor model is placed with a predetermined process item in the process data. and a site status display step for displaying on a screen the site status of a specified construction portion of the three-dimensional design model as the time axis progresses. The measurement management step further includes a measurement data reference step and a measurement value control value comparison step. In the measurement value control value comparison step, sensing data from the measurement sensor as the time axis progresses during construction of the specified process item, referenced in the measurement data reference step based on data relating to the start time of the performance of the specified process item in the process data, is compared with a control value set for the specified process item. In the site status display step, the sensor model that can reflect sensing data information is displayed on a screen of the specified construction portion of the three-dimensional design model in which the displayed sensor model is placed, and the comparison result between the sensing data compared in the measurement value control value comparison step and the control value is visualized, thereby achieving the above-mentioned object.

Furthermore, the present invention provides a construction management program for managing the construction of a building using a 3D model analysis program, which causes a computer to execute a measurement management step that enables management of the construction of a building based on 3D design data of a 3D design model of the building created using a 3D CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors regarding the surrounding ground, temporary structures, or existing structures when constructing the building; the 3D design data of the 3D design model of the building is created in a state in which sensor models that are linked to measuring equipment using each measurement sensor and can reflect information on sensing data measured by each measurement sensor are placed at predetermined locations on the 3D design model that require measurement by the measurement sensors; the measurement management step includes a construction linking step that associates design data for a predetermined construction portion of the 3D design model in which the sensor model is placed with a predetermined process item in the process data; and a construction linking step that associates design data for a predetermined construction portion of the 3D design model in which the sensor model is placed with a predetermined process item in the process data before the sensor model is placed. The above-mentioned objectives are achieved by providing a construction management program for managing construction of a building by causing a computer to execute a site situation display step for displaying on a screen the site situation of a specified construction portion of the three-dimensional design model as the time axis progresses; and in the measurement management step, the computer further executes a measurement data reference step for referencing sensing data from the measurement sensor as the time axis progresses during construction of the specified process item based on data relating to the start time of the performance of the specified process item in the process data; and a measurement value control value comparison step for comparing the sensing data from the measurement sensor referenced in the measurement data reference step with a control value set for each specified process item. The above-mentioned objectives are achieved by providing a construction management program for managing construction of a building by causing a computer to execute a site situation display step for displaying on a screen the site situation of a specified construction portion of the three-dimensional design model in which the displayed sensor model is placed, together with the sensor model capable of reflecting sensing data information, thereby visualizing the comparison result between the sensing data compared in the measurement value control value comparison step and the control value.

The construction management device, construction management method, and construction management program of the present invention allow for the daily changing site conditions to be reflected, and measurement data from measurement sensors such as IoT sensors can be easily and appropriately grasped along with management values in a four-dimensional model of the construction site to manage the site conditions.

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

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

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

The measurement management unit 11 includes a construction linking unit 15 that associates 3D design data of a specific construction portion of the 3D design model 30 of the building in which the sensor model 31 is placed with a specific process item 33 in the process data (see Figures 9 and 10) that requires measurement by a measurement sensor, for example, and a site status display unit 16 that displays on-screen data on the site status over time for the specific construction portion of the 3D design model 30 of the building in which the sensor model 31 is placed. 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 from the measurement sensor over time during construction of the specific process item 33, referenced by the measurement data reference unit 19 based on data on the actual start date and time of the specific process item 33 in the process data, with the control value set for each specific process item 33. The site status display unit 16 visualizes the results of the comparison between the sensing data and the control values compared by the measurement value control value comparison unit 24, along with the sensor model 31 that can reflect 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 management of the construction of the building.

In this embodiment, the sensing data, preferably from an IoT sensor, referenced by the measurement data reference unit 19 is, for example, data in the measurement management system 20 described below.

The building construction management device 10 of this embodiment preferably includes a 3D design data storage unit 12 that stores 3D design data, a process data storage unit 13 that stores process data, and a sensing data storage unit 14 that stores sensing data measured by each measurement sensor.

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

In this embodiment, a well-known three-dimensional model analysis program is incorporated into the computer-based construction management device 10, and the three-dimensional model analysis program has functions for creating three-dimensional models, displaying point clouds, acquiring information, and analyzing it. The three-dimensional model analysis program can provide the software side with a development environment for implementing the measurement management unit 11, which includes various memory units 12, 13, and 14, a data acquisition unit 17, a construction linking unit 15, a measurement data reference unit 19, a site status display unit 16, a control value setting unit 23, a measurement value control value comparison unit 24, and a warning information issuance unit 25, as described below. An example of a three-dimensional model analysis program (three-dimensional model analysis software) that can provide such a development environment to the software side is the PADS software manufactured by Pasco Corporation.

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

Preferably, the 3D CAD program (3D CAD software) for incorporating the 3D design model creation unit 21a into the 3D design device 21 is "Revit" by Autodesk, a BIM tool capable of creating BIM models. The 3D design model 30 of the construction site, including the temporary structure model 30b created by the 3D design model creation unit 21a, includes sensor models 31 (see Figures 3 and 4), each of which is a 3D object and is preferably an icon modeling the shape of measuring equipment 42 using each measurement sensor, and which can reflect sensing data information measured by the measurement sensors, as described below. These sensor models 31 are preferably arranged at predetermined locations requiring measurement by the measurement sensors.

In addition, 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 constructing a railway box 41, a construction to be installed adjacent to an in-service track 40, as a main structure. The process data for constructing the railway box 41, a construction, can be created by a process data creation unit 22a using a known process management program incorporated in a process management device 22 separate from the construction management device 10, and can be imported into the construction management device 10 via, 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 constructing the railway box 41, a construction, can also be created by a process data creation unit 22a using a known process management program incorporated in the construction management device 10, and can be stored in the process data storage unit 13.

Preferably, the process management program (process management software) for incorporating the process data creation unit 22a into the process management device 22 is "Being Project-CCPM" by Being Corporation, a program with CCPM (Critical Chain Project Management) functionality. 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 divided construction site, as well as process duration information consisting of the planned start and end dates of each process. The process items 33 consist of items such as rebar assembly, scaffolding assembly, shoring assembly, formwork assembly, and removal of temporary materials (scaffolding, shoring, formwork) for each specified construction site.

Here, the preferred process management program with CCPM functionality is process management software (process management program) that employs critical chain project management (CCPM), developed with a view to overall optimization based on the theory of constraints (TOC). Critical chain is a methodology that considers dependencies in the work process when determining the execution order of each task in a project, in addition to the traditional critical path method, which considers dependencies in the work process. Project management is a practical methodology for project management that aims to shorten construction time and meet delivery deadlines, taking into account the human psychology and behavioral characteristics of personnel, as well as social and organizational issues. The safety margins removed from each task are aggregated and managed in a "buffer." Process management programs with CCPM functionality also preferably have functions for incorporating cost estimation information, setting daily construction volumes and non-work days, and setting critical paths (CPs). Preferably, a process management program that does not have a CCPM function can be used as a process management program for incorporating the process data creation unit 22a into the process management device 22.

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

When constructing a railway box 41 as the main structure, a measurement management system 20 is preferably used to acquire and manage sensing data (measurement data) measured by measurement sensors, preferably IoT sensors, such as a management system manufactured by Keisoku Techno Co., Ltd. Data related to displacement, changes, or loads on the surrounding ground, temporary structures, existing structures, etc., measured by measurement sensors, preferably IoT sensors, during construction of the building, includes, for example, construction base settlement, overhead line pole settlement, strut axial force, retaining wall horizontal displacement, rebound, on-site groundwater level, off-site groundwater level, intermediate zone displacement, retaining wall internal displacement, strut temperature, etc. Measurement devices 42, preferably using IoT sensors as measurement sensors to measure this sensing data, include, for example, water-filled settlement gauges, small inclinometers, strain gauges, multi-stage inclinometers, rock inclinometers, pore water pressure gauges, water level gauges, laser distance sensors, thermometers, etc.

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

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

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

It is also preferable that the measurement values (sensing data) are output in CSV format from the measurement management system 20. The measurement values (sensing data), together with attribute information based on the measuring equipment information, are preferably referenced by the measurement data reference unit 19 or stored in the sensing data storage unit 14 of the measurement management system 20.

On the other hand, the control value data indicates the threshold value of the measurement value (sensing data) obtained by the measurement sensor, and can be used to perform management such as issuing an alert when the measurement value exceeds the control value.

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

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

Therefore, in this embodiment, the 3D design data for the 3D design model 30 of a building whose main structure is a railway box 41 is created by linking sensor models 31 that are linked to measuring devices 42 using each measurement sensor (IoT sensor) and can reflect the sensing data information measured by each measurement sensor, and placing the sensor models 31 at predetermined locations on the 3D design model 30 of the building that require measurement by the measurement sensors.

As described above, the construction management device 10 of this embodiment is equipped with a measurement management unit 11 that enables management of construction of a building based on three-dimensional design data of the three-dimensional design model 30 of the building, which includes a model 30b of a temporary structure, process data for constructing the building, and sensing data measured by a measurement sensor regarding the surrounding ground, temporary structures, or existing structures when constructing the building. The measurement management unit 11 further includes a construction linking unit 15 that associates 3D design data of a predetermined construction portion, preferably divided into work sections, of the 3D design model 30 of the building in which the sensor model 31 is 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 over time of a predetermined construction portion, preferably divided into work sections, of the 3D design model 30 of the building in which the sensor model 31 is arranged; a measurement data reference unit 19 that references sensing data from the measurement sensor over time during construction of the predetermined process item 33 based on data related to the actual start date and time of the predetermined process item 33 in the process data; a control value setting unit 23; and a measurement value/control value comparison unit 24.

In this embodiment, the construction linking unit 15 of the measurement management unit 11 preferably acquires, via the data acquisition unit 17, design data for the 3D design model 30 of the building on which the sensor model 31 is placed, including the model of the temporary construction section 30b, where the model of the railway box 41, which is the building, is the main structure model 30a, and which is stored in the 3D design data storage unit 12, and process data, preferably stored in the process data storage unit 13, and associates these to create a 4D model, and also performs a 4D simulation of the planned construction status of the railway box 41, which can be displayed, for example, on a display screen. In other words, the construction linking unit 15 associates the design data for the 3D design model 30 of the building on which the sensor model 31 is placed with the process data to create a 4D model, thereby enabling the planned construction status of the building, from start to finish, to be displayed on the screen.

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. As shown in FIG. 9, the process/status linking unit 15a allows workers to edit the component status 32 by assigning different colors 32a to each status item, such as "rebar," "formwork," "concrete pouring," "curing," "under construction," "completed," "temporary," "removing," "removed," "not started," "waiting," "not displayed after completion," "cleaning," and "under construction - watermark." The edited results are stored in the component status storage unit 18 of the measurement management unit 11. Furthermore, the process/status linking unit 15a can set, for each process item 33 that constitutes the process data for constructing a specific construction portion of a building, preferably divided into work sections, a component status 33a during the process period and a component status 33b after the process period have elapsed, each color-coded by a different color 32a, and link these process items 33 to the component statuses 33a, 33b during the process period and after the process period have elapsed. The process/status linking unit 15a performs the component status editing step S4 and the process/status linking step S5, which will be described later.

As shown in FIG. 9, the process/model linking unit 15b selects one or more of the process items 33 constituting the construction process data, which are displayed as a schedule, for each data point, preferably divided into sections, of the three-dimensional design model 30 of the construction, including the temporary structure model 30b, which is displayed in a hierarchical structure on the screen, and links the data of the specified construction section in the three-dimensional design model 30 of the construction to these process items 33. Linking the specified construction section in the three-dimensional design model 30 of the construction, including the temporary structure model 30b, to the process items 33 can be easily performed by, for example, including common numbers or symbols between the ID numbers of the process items 33 containing data related to each process item 33 and the ID numbers of the models (objects) included in the data related to the models 30a, 30b, 30c of the structures and the surrounding ground model 30d that make up the three-dimensional design model 30 of the construction. Furthermore, since the process items 33 are linked to component statuses 33a, 33b during and after the process period in the process/status linking unit 15a (see Figures 6 and 9), it is possible to link component statuses 33a, 33b during and after the process period for each process item 33 for each specific construction site data. It is also possible to set the initial status before the process for a specific construction site begins. As a result, as each process progresses, it is possible to set the progress of construction for each specific construction site in the 3D design model 30 of the building, for example, by changing color. The process/model linking unit 15b performs the process/model linking step S6, which will be described later.

In this embodiment, the measurement data reference unit 19 of the measurement management unit 11 references sensing data managed, for example, in the measurement management system 20, based on data related to the actual start date and time of a specific process item 33 in the process data; more specifically, based on data related to the measurement date and time included in the measurement value information from each measuring device 42, preferably at each specific date and time during the construction of the specific process item 33. As a result, the measurement data reference unit 19 has the function of enabling the site status display unit 16, described below, to visualize the sensing data referenced by the measurement data reference unit 19 included in the measurement value information as time-series data of the site status over time as the construction of the specific process item 33 progresses, together with the control value for the process item 33 set by the control value setting unit 23, in real time or as past data on a screen displaying the 3D design model 30 of the building in which the sensor model 31 is placed. The measurement data reference unit 19 performs the measurement data reference step S8, described below.

In addition, in this embodiment, the measurement management unit 11 is equipped with a control value setting unit 23 that can associate each of the multiple process items 33 created by the process data creation unit 22a of the process management device 22 with one or more control values of the control value information contained in the control value data of each measuring device 42 managed by the measurement management system 20, and can set or change control values for each of these process items 33. For example, the control value is reviewed for each measurement sensor (IoT sensor) of a specific measuring device 42 that is required to obtain measurement data during the construction of that process item 33, and the control value setting unit 23 resets or changes the control value for each process item 33 by inputting the control value data, preferably by a worker, in association with each process item 33. The control value setting unit 23 can also store data associating these process items 33 with the control values of specific measuring devices 42, for example, in a storage table, and can be set so that the control value corresponding to the next process item 33 is automatically replaced upon completion of each process item 33. The management value setting unit 23 performs the management value setting step S7, which will be described later.

Here, the control values of measurement data obtained by measuring devices 42 using specified measurement sensors may need to be set or changed for each process item 33 as construction progresses. For example, as shown in FIG. 4, if the process item 33 for a specified construction site, preferably divided into sections, is excavation and retaining work, and the 3D object at the specified construction site in the 3D design model 30 of the building is a strut model serving as a temporary structure 30b, the control values of measurement data obtained by a strain gauge attached to a specified installation location, such as the first strut, need to be changed for each of these more detailed process items 33 when excavating the ground to construct the first strut and when excavating the ground to construct the second and third struts. For this reason, for example, a worker inputs control value data for measuring devices 42 using specified measurement sensors for each process item 33, as described above, and the control value setting unit 23 sets or changes the control values for each of these more detailed process items 33.

Furthermore, for measuring devices 42 using each measurement sensor, the control values set for each specified process item 33 may preferably include comparison control values at multiple levels. Six types of comparison control values at multiple levels can be used, for example: "+primary control value," "+secondary control value," "+tertiary control value," "-primary control value," "-secondary control value," and "-tertiary control value." Preferably, the comparison control value can be, for example, the primary control value equal to the design control value x 0.8, the secondary control value equal to the design control value itself, and the tertiary control value (limit control value) equal to the design control value x 1.2.

In this embodiment, the measurement management unit 11 is equipped with a measurement value control value comparison unit 24, which, as described above, compares sensing data from measurement sensors obtained over time during the construction of a specific process item, referenced by the measurement data reference unit 19 based on data related to the actual start date and time of the specific process item 33 in the process data, with the control value preferably set or changed for each specific process item 33 by the control value setting unit 23. The comparison results between the sensing data and the control value for each process item 33 compared by the measurement value control value comparison unit 24 are visualized, for example, by the site status display unit 16 on a screen of a specific construction site in the 3D design model 30 of the building in which the sensor model 31 is placed, together with the sensor model 31, which can reflect the sensing data information, thereby enabling more appropriate management of the construction of the building. The measurement value control value comparison unit 24 performs the measurement value control value comparison step S9, which will be described later.

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

That is, according to this embodiment, the 3D design data (4D design data) linked to the process data for the 3D design model 30 of the construction, including the model 30b of the temporary structure, whose main structure is a railway box 41 installed adjacent to an in-service track 40, is created by linking the sensor models 31, which can reflect information on sensing data measured by the respective measurement sensors, to the measuring instruments 42 using the respective measurement sensors, and placing them in predetermined locations, preferably in predetermined construction areas divided into work zones, on the 3D design model 30 of the construction that require measurement by the respective measurement sensors. As a result, for example, by specifying the sensor model 31, the sensing data measured by the measurement sensors, preferably IoT sensors, and referenced by the measurement data reference unit 19 in the measurement management system 20 or the sensing data storage unit 14, together with the sensor model 31, can be displayed on the screen of the construction management device 10 as a time-lapse diagram, list, or the like, together with the management values, in a state where the measurement location can be easily grasped. The displayed measurement data makes it possible to easily and appropriately manage the on-site situation at the construction site (see Figures 11 and 12). It also makes it easy to determine whether the measurement value has exceeded the control value, making it possible to more appropriately manage the on-site situation at the construction site.

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

In addition, according to this embodiment, the measurement data reference unit 19 can directly reference sensing data, for example, imported from a measurement sensor into the measurement management system 20 via a wired or wireless network, and display the sensing data on the screen as real-time data on the site situation as the construction of the specified process item 33 progresses along the timeline. This makes it possible to grasp the measurement position on the screen using the sensor model 31 via sensing data from the measuring devices 42 using each measurement sensor, and manage the site situation in real time using the control values set or changed by the control value setting unit 23 in accordance with the progress of construction. This also makes it possible, for example, to issue warning information by the warning information issuing unit 25 (described below) when the sensing data, which changes as construction progresses at a specified location on the construction site where the measuring devices 42 are installed, approaches or exceeds the control value set or changed by the control value setting unit 23, so that a warning can be issued to warn the worker or to suspend work and take appropriate measures.

Furthermore, in this embodiment, a time bar, for example, can be set on the screen displaying a specified construction site of the 3D design model (4D design model) 30, which includes a model 30b of a temporary structure linked to the process data of each process item 33. This allows the on-site situation accompanying the progress of a specified construction site to be displayed on the screen along the time axis of the time bar, along with the transition of sensing data based on the measurement date and time of the measurement value information, making it possible to visualize changes in sensing data over time in an easy-to-understand manner on the screen, preferably using control values, and, preferably, by specifying a date and time on the time bar, it becomes possible to display the sensing data for the specified date and time on the screen, preferably together with the control values.

Furthermore, in the building 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 imported and stored in the sensing data storage unit 14 along with measuring equipment information and management value information. This makes it possible for the measurement value information including sensing data, together with the management value information, to be referenced by the measurement data reference unit 19 as reproducible data, and to be used as reference material, preferably when constructing buildings at other similar construction sites.

In addition, in this embodiment, for example, by clicking and specifying a sensor model 31, the sensing data measured by the measurement sensor, preferably an IoT sensor, for that sensor model 31 is displayed together with the control value. The sensing data is referenced by the measurement data reference unit 19 and can be visualized together with the control value on the screen of the display of the construction management device 10, for example, as a time-series diagram or list (see Figures 11 and 12). Here, the time-series diagram displayed 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, along with a line of the control value. The list display displays the measurement value (sensing data) along the time axis for each measurement item. For example, if a measurement value exceeds the control value, the color of the cell in the corresponding column can be changed in stages. By selecting a specific measurement value from the list of measurement values, the measurement value can be transitioned to the sensor model 31 corresponding to the selected measurement value in the model space on the screen.

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, simulating a measuring device 42. The measurement management unit 11 preferably further includes a warning information issuing unit 25. The warning information issuing unit 25 compares the sensing data measured by the measurement sensor with the control values set or changed by the measurement value control value comparison unit 24 described above. When the sensing data exceeds, for example, the secondary or tertiary control value of the comparison control value, 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, for example, to yellow or red, preferably via the site status display unit 16. The warning information issuing unit 25 can also issue warning information in real time by sound, such as an alarm, when the sensing data measured by the measurement sensor exceeds, for example, the secondary or tertiary control value of the comparison control value.

In this embodiment, the icon 31 is preferably displayed in an exaggerated form larger than the external shape of the actual measuring device 42 so that the type and installation location can be identified at a glance. The icon, which is a sensor model 31 that mimics the shape of the measuring device 42, can have its color changed by the site status display unit 16 depending on the sensing data and management value measured by the measurement sensor associated with it.

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

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

In the 3D design model import step S2, design data for a 3D design model 30 of a building, preferably of a divided construction section, of a construction whose main structure is a railway box 41, created using 3D CAD software and stored in the 3D design data storage unit 12, is acquired from the 3D design data storage unit 12, preferably by the data acquisition unit 17 in data acquisition step S1, and imported into the measurement management unit 11. The imported design data for the 3D design model 30 of the building is created by linking sensor models 31, which are linked to measuring equipment 42 using each measurement sensor and can reflect sensing data information, to predetermined locations on the 3D design model 30 of the building that requires measurement by the measurement sensor.

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

In the component status editing step S4, in the process/status linking unit 15a of the construction linking unit 15 described above, as shown in FIG. 9, the worker operates the screen to assign a different color 32a to each component status 32, such as "rebar," "formwork," "concrete pouring," "curing," "under construction," "completed," "temporary," "removing," "removed," "not started," "waiting," "not displayed after completion," "cleaning," "under construction - watermark," "during construction," "after construction period has elapsed," and "initial status before construction begins." This sets the color to be displayed according to the component status 32 when the construction status of a specific part of the building is displayed on the screen using the 3D design model 30 of the building, and edits these component statuses 32.

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

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

The control value setting step S7 is preferably performed in the control value setting unit 23 described above prior to the measurement data reference step S8. In the control value setting step S7, a new control value can be set or changed by inputting control value data, preferably by an operator, for each measurement sensor (IoT sensor) of a specified measuring device 42 that is required to obtain measurement data during the construction of the process item 33, in association with each of the multiple process items 33 in the process data imported in the process data import step S3.

The measurement data reference step S8 is performed by the measurement data reference unit 19 described above. In the measurement data reference step S8, sensing data managed by the measurement management system 20 or stored in the sensing data storage unit 14 is referenced, preferably for each specified date and time for the specified process item 33 currently under construction, based on data related to the actual start date and time of the specified process item 33 in the process data. This makes it possible, preferably in the site status display step S10 described below, to visualize the referenced sensing data in real time or as past data on a screen displaying the 3D design model 30 of the building in which the sensor model 31 is placed, together with the control value set in the control value setting step S7, as time-series data on the site status as the time axis of the specified process item 33 currently under construction progresses.

The measurement value control value comparison step S9 is performed by the measurement value control value comparison unit 24 described above. As shown in FIG. 8, the measurement value control value comparison step S9 imports control values having one or more comparative control values (primary control value through nth-order control value) set for each measurement sensor (IoT sensor) of a specific measuring device 42 for which measurement data must be obtained during the construction of that process item 33 in the process data. The imported control values are then sequentially compared with the sensing data of the specific measuring device 42 measured during the construction of that process item 33 referenced in the measurement data reference step S8 to determine whether, for example, each of the one or more comparative control values has been exceeded. If it is determined that any comparative control value has been exceeded, a warning information is issued promptly, preferably in real time, by changing the color of an icon, for example, a sensor model 31, via the warning information issuance step S10' in the site status display step S10 described below, thereby urging the construction site to take necessary measures, for example.

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 associated with the timeline from the start to the end of construction, associated with process data, at a specific construction site, preferably divided into sections, of a construction whose main structure is a railway box 41, is reproduced using a three-dimensional design model 30 of the construction, including a sensor model 31 that can reflect information from sensing data of the construction, and can be displayed on the screen together with visualized sensing data and control value data (see Figures 11 and 12).

The warning information issuing step S10' is performed by 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 site status display unit 16 can promptly issue warning information in real time via the sensor model 31 or promptly issue an alarm sound.

Therefore, the construction management method for managing construction of a building using the 3D model analysis program of this embodiment includes measurement management steps (S4, S5, S6, S7, S8, S9, S10) that enable management of construction of a building based on 3D design data of a 3D design model 30 of the building created using a 3D CAD program, process data for constructing the building created using a process management program, and sensing data measured by measurement sensors regarding the surrounding ground, temporary structures, or existing structures when constructing the building, and includes the 3D model analysis of the building.
