[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. 1 is a diagram showing an example of the functional configuration of a construction management system 1 according to the present embodiment. The construction management system 1 judges the quality of construction based on operation data obtained from a construction system 50.

[0012] [Installation system] The construction system 50 includes a construction machine 51 and a construction machine management device 500. The construction machine 51 is a heavy machine for carrying out ground improvement work at a building construction site. The construction machine 51 may employ any construction method for ground improvement work, such as a construction method for forming a columnar body in the ground by pouring a liquid solidification material (e.g., cement milk) into the ground, or a construction method for burying (or driving) an object formed in advance into a columnar shape (e.g., a steel pipe pile) into the ground. In the following description, the objects buried in the ground by these construction methods are collectively referred to as "ground improvement bodies." In other words, the ground improvement bodies are columnar bodies or foundation piles that are constructed in the ground for the purpose of ground improvement. That is, the construction machine 51 (construction machine) is a machine for constructing ground improvement bodies, which are columnar bodies or foundation piles, in the ground.

[0013] For example, the construction machine 51 (construction machine) may be one that constructs a ground improvement body by rotating a construction head by a rotating shaft to which a predetermined rotational torque is applied and pouring cement milk into the ground. In this case, the construction machine 51 includes a construction head, a rotating shaft, a flow pipe for cement milk, etc. The construction machine 51 (construction machine) may be one that buries the ground improvement body in the ground by rotating the construction head with a rotating shaft to which a predetermined rotational torque is applied. In this case, the construction machine 51 includes a construction head, a rotating shaft, etc.

[0014] In the following description, the columnar bodies or foundation piles (i.e., ground improvement bodies) that are constructed in the ground for ground improvement purposes will also be referred to simply as "piles".

[0015] The construction machine management device 500 is a computer device provided in the construction machine 51. The construction machine management device 500 includes a management device calculation unit 510 and a management device storage unit 520. The management device calculation unit 510 controls the operating parts of the construction machine 51 (e.g., the head, the rotating shaft, the cement milk pump, etc.) and measures the operating states of the operating parts using sensors or the like. The construction machine 51 stores the measured operating states as operating data in the management device storage unit 520. The management device storage unit 520 stores the operating data indicating the operating states of the construction machine 51.

[0016] For example, there is a case where the construction machine 51 (construction machine) constructs a ground improvement body in the ground by rotating a construction head by a rotating shaft to which a predetermined rotational torque is applied. In this case, the operation data includes at least one of information regarding the depth of the construction head of the construction machine 51 (construction machinery), the rotation speed of the rotating shaft, the rotational torque value of the rotating shaft, or the flow rate of cement poured into the ground during construction.

[0017] The operation data stored in the management device memory unit 520 can be output to a computer device (e.g., the on-site terminal device 400) other than the computer device of the construction machine 51 (construction machinery) via wireless or wired communication or a removable storage medium (e.g., a USB (Universal Serial Bus) memory). In this case, the operation data can be said to be data that is the measurement values ​​of the operating state acquired by the construction machine management device 500 (computer device) of the construction machine 51 (construction machine) and output to a site terminal device 400 (computer device) other than the computer device of the construction machine 51 (construction machine).

[0018] [Construction management system] The construction management system 1 includes an office terminal device 100, a server 200, a manager terminal device 300, and a field terminal device 400.

[0019] The office terminal device 100 is a computer device provided in an office where design and construction management of a property to be improved on are performed, and includes, for example, a display device such as a liquid crystal display, and an input device such as a keyboard and a mouse. In general, the office where design and construction management of a property to be improved on are performed is located away (i.e., a remote location) from the location of the property to be improved on (i.e., the construction site).

[0020] The server 200 is connected to the office terminal device 100 via a network N. The server 200 may be installed in a building (i.e., an office) in which the office terminal device 100 is installed, or may be installed in a remote location outside the office. The server 200 may also be configured as a logical device (e.g., a cloud server) in which a plurality of physical computer devices are interconnected to provide functions.

[0021] The server 200 includes a server computing unit 210 and a server storage unit 220. The server computing unit 210 is a computer device that provides various functions. The server storage unit 220 includes a hard disk device and a semiconductor memory, and stores programs and data for the server computing unit 210 to operate.

[0022] The manager terminal device 300 is a computer device operated by a manager of a construction site (for example, a site manager), and is capable of communicating with the server 200 and the site terminal device 400 via the network N. The on-site terminal device 400 is a computer device operated by a worker at a construction site, and is capable of communicating with the server 200 and the manager terminal device 300 via the network N.

[0023] An example of the flow of operations of the construction management system 1 configured by these computer devices will be described below with reference to FIGS. As described above, communication between the computers is performed via the network N, but in the following description, the description of communication via the network N will be omitted.

[0024] 2 and 3 are diagrams showing an example of the flow of operations of the construction management system 1 of this embodiment.

[0025] [Registering design specification data for each property (pre-construction)] (Step S110) In the office terminal device 100, property information is registered, and property-specific design specification data D200 is created from the registered information. (Step S120) The office terminal device 100 transmits the property-specific design specification data D200 to the server 200. The registration of property information and the property-specific design specification data D200 will be described with reference to Figs.

[0026] Fig. 4 is a diagram showing an example of the layout of construction positions. The diagram shows the layout of ground improvement bodies at a construction site of a certain property. This property is, for example, an industrialized housing structure with a concrete foundation and a continuous slab footing with an inverted T-shaped cross section. A ground improvement body is constructed below the continuous slab footing. The ground improvement body is placed on a grid based on the center line (X-axis, Y-axis), which is the reference line for placing the continuous slab footing. A diagram showing the layout of ground improvement bodies, as in the figure above, is also called a "pile plan." In the example shown in the figure, n piles, from pile No. 1 to pile No. n, will be constructed.

[0027] 5 to 7 are diagrams showing an example of the property registration screen P110. The property registration screen P110 is a screen displayed on the display unit of the office terminal device 100. The property registration screen P110 includes a property registration screen P110-1 showing basic information about a property, a property registration screen P110-2 showing a construction plan (including information about design specifications and values ​​of the design specifications), and a property registration screen P110-3.

[0028] 5 shows an example of a property registration screen P110-1 showing basic information about a property. The property registration screen P110-1 has an input field for the "construction method" of the ground improvement body along with the "contract number," "property name," "construction site," etc., as basic information about the property, and allows the user to select and input the type of construction method (cement ground improvement method, steel pipe pile method, etc.) from the menu. Here, the grind column method (the name of the cement ground improvement method) is selected. In the following description, the information entered on the property registration screen P110-1 is also referred to as basic property information (or simply basic information).

[0029] FIG. 6 shows an example of the property registration screen P110-2 showing a construction plan. The property registration screen P110 displays property information for each contract number. A contract number is a number uniquely assigned to each property (i.e., each construction site) and is information that identifies each property from another. By managing design specification data for each contract number, the construction management system 1 can manage construction plans for each property when construction conditions such as the site geology and building scale differ from property to property. In the following description, the property that is the subject of property registration in step S110 is also referred to as "the property identified by the contract number," "the property in question," or "this property."

[0030] 7 shows an example of the property registration screen P110-3 showing the construction plan. At the time of step S110, before construction, the cement specific gravity and the water-cement ratio (water solidification material ratio) are input. Note that, after construction, these input fields are used to additionally input (overwrite) the values ​​actually used on-site as the construction results. In the following description, the information on the design specifications regarding the piles input on the object registration screen P110-2 and the object registration screen P110-3 is also referred to as construction plan information for the object (or simply as construction plan).

[0031] Fig. 8 is a diagram showing an example of the pile construction condition registration screen P120. The pile construction condition registration screen P120 is a tabular screen automatically generated based on the values ​​of the ground improvement construction method, specifications, and design specifications registered in Fig. 5 to Fig. 7 for multiple piles constructed in the property, and is a screen for registering construction conditions for each pile. The pile construction condition registration screen P120 is displayed on the display unit of the office terminal device 100, and the pile construction conditions are registered by the operator of the office terminal device 100.

[0032] The initial values ​​of the automatically generated construction conditions in Figure 8 can be changed. For example, the top end (column top) of the column, which is a ground improvement body, is designed to support the bottom plate of the concrete foundation at the "design embedment depth" from the design ground surface (design ground line (GL)) toward the ground (downward). In some cases, deep foundations (non-standard foundations) are designed as part of the standard concrete foundations (standard foundations) for the same property. For example, pile numbers 1 and 2 in Figure 4 are designed to support the bottom plate of the concrete foundation at 705mm, which is 300mm added to the standard embedment depth of 405mm.

[0033] In such a case, it is possible to change the initial value of 0 (unit: mm) for the "DN (down) amount" of the corresponding pile numbers No. 1 and No. 2 in Figure 8 to 300 (unit: mm) based on the design documents (not shown) for the property and the pile plan in Figure 4. This makes it possible to correctly set the position of the column top in the ground for each pile number.

[0034] For the above-mentioned "design embedment depth", the value displayed in the corresponding field shown on the property registration screen in Fig. 7 is used. This value can be input by the inputter as appropriate based on the design drawings and documents of the property, but it may also be calculated automatically. Specifically, it can be calculated automatically using the value of the beam depth dimension of the standard foundation associated with the "building type" in Fig. 6 included in the property-specific design specification data D200 of this embodiment, and the value of the height dimension from the design GL to the top end (Z0) of the foundation beam in Fig. 7 ("Z0 = GL + "). Furthermore, if these values ​​are entered into the "Non-standard foundation" field in Figure 6, these values ​​can also be used in combination to automatically calculate the "design embedment depth" for non-standard concrete foundations.

[0035] When the “Update” button (not shown) on the property registration screen P110-2 shown in Figure 6 is operated, the office terminal device 100 sends to the server 200 property-specific design specification data D200, which contains the basic information in Figure 5, the construction plans in Figures 6 and 7, and a list of construction conditions for each pile in Figure 8.

[0036] 9 is a diagram showing an example of the property-specific design specification data D200 of this embodiment. The property-specific design specification data D200 includes the contract number, name, construction site, construction method type, model of the construction machine 51 used in the ground improvement work, and design specification values ​​for each pile.

[0037] In this case, the communication unit 211 of the server 200 functions as a property-specific design specification data acquisition unit that acquires the construction method, specifications, or design data of the ground improvement body related to the property to be constructed as property-specific design specification data.

[0038] The type of construction method is not limited to the grind column method (a name of a cement ground improvement construction method) described above, and is also not limited to the EAZET method (a name of a steel pipe buried pile construction method), and may include various cement ground improvement construction methods and steel pipe pile construction methods. In addition, as another construction method, for example, a concrete pile construction method may be selected. Additionally, the design specification values ​​that are common to all construction methods include the number of columns, column length, design embedment depth, DN, column diameter (diameter of the column's horizontal cross section), diameter of the drilling or mixing blades on the rotating shaft (dimension of protrusion from the shaft), number of blades, long-term allowable bearing capacity of the column, and whether or not the supporting ground is inclined.In the Grind Column method, the amount of cement added, cement specific gravity, water-cement (solidification material) ratio, and consideration of peripheral friction are also included.In the EAZET method, the short-term torsional strength of the steel pipe and the control torque value are also included.

[0039] (Step S210) Returning to Fig. 2, when the property-specific design specification data D200 is transmitted from the office terminal device 100, the server 200 stores the property-specific design specification data D200 in the server storage unit 220. Note that transmitting the property-specific design specification data D200 from the office terminal device 100 to the server 200 and storing it in the server storage unit 220 is also referred to as registering the property-specific design specification data D200. The server storage unit 220 stores property-specific design specification data D200 for each property. This property-specific design specification data D200 can be viewed and updated from each terminal device of the office terminal device 100, the manager terminal device 300, and the field terminal device 400.

[0040] [At the start of construction] (Step S410) The on-site terminal device 400 accesses the server 200 and selects the individual property design specification data D200 of the property from among a plurality of individual property design specification data D200 (property list information).

[0041] 10 is a diagram showing an example of a property selection screen P410 of this embodiment. The on-site terminal device 400 accesses the server 200 and acquires the property number (contract number), property name, construction site (e.g., the location of the construction site), work date and time, person in charge, and the like of each of the multiple property-specific design specification data D200. The acquired information can be said to be items that allow a person operating the on-site terminal device 400 (e.g., a site manager or a construction machine operator) to specify the property-specific design specification data D200 of the construction target property that he or she is in charge of. The on-site terminal device 400 displays the acquired information as a property selection screen P410. In this way, the on-site terminal device 400 includes items for identifying the property-specific design specification data D200, so that a user of the on-site terminal device 400 (e.g., a construction worker at the on-site) can efficiently (e.g., without error) select the property-specific design specification data D200 for the property from among multiple property-specific design specification data D200.

[0042] It is also preferable to provide a function for narrowing down or searching when selecting from among multiple property-specific design specification data D200. For example, it is conceivable to calculate the degree of coincidence between the "location information (latitude and longitude)" output by the GPS measuring device installed in the on-site terminal device 400 or the construction machine 51 (construction machine management device 500) and the location information (latitude and longitude) converted from the "construction site" of the property-specific design specification data D200, and to preferentially display property numbers with larger values ​​and to find matching properties.

[0043] (Step S420) The on-site terminal device 400 generates report information based on the user's operation. The report information is information that compiles photos and conditions of the site before and after construction, the construction results, signatures of on-site witnesses, etc. The report information is transmitted from the on-site terminal device 400 to the server 200 and stored in the server storage unit 220. The report information can be viewed by the office terminal device 100, the manager terminal device 300, and the on-site terminal device 400. An example of the operation of generating report information will be described with reference to FIG. 11.

[0044] 11 is a diagram showing an example of a property status registration screen P411 of this embodiment. The property status registration screen P411 is an operation image for selecting photos to be included in report information from among photos of the site taken by a camera (not shown) of the on-site terminal device 400 or the like. The user of the on-site terminal device 400 selects photos to be included in a report document from among the photos displayed on the property status registration screen P411.

[0045] 12 is a diagram showing an example of the on-site attendance record registration screen P412 of this embodiment. The on-site attendance record registration screen P412 is an image for the on-site attendant to sign the report information. When the on-site terminal device 400 detects an operation of writing a signature by the on-site attendant (for example, an operation of writing a name by operating a touch panel of the on-site terminal device 400 (tablet, smartphone)), the on-site terminal device 400 adds the detected signature to the report information.

[0046] [Under construction] (Step S510) The management device calculation unit 510 of the construction machine management device 500 generates operation data based on the measurement values ​​obtained by measuring the operating state of the operating part of the construction machine 51.

[0047] 13 is a diagram showing an example of a construction status display screen P510 of this embodiment. The construction machine management device 500 displays the construction status display screen P510 on a display unit (not shown) installed in the operator's cab of the construction machine 51. The operator of the construction machine 51 operates the construction machine 51 while looking at the construction status display screen P510. On the construction status display screen P510, an operation data record button P511, an object identification display field P512, a construction date and time display field P513, and an operation data display field P514 are displayed.

[0048] The operation data record button P511 is a button image that accepts operation by the operator. When the operation data record button P511 is operated, the management device calculation unit 510 generates operation data based on the measurement values ​​of the operating state, and stores the generated operation data in the management device storage unit 520. While the operation data continues to be stored in the management device storage unit 520, "Operation data recording" is displayed on the construction status display screen P510. When the operation data record button P511 is operated again, the management device calculation unit 510 stops the operation of storing the operation data in the management device storage unit 520. The management device calculation unit 510 may have a function of determining whether construction has started or ended for each pile based on the operation state of the construction machine 51. In this case, the management device calculation unit 510 may start storing operation data when it determines that construction of a pile has started, and may stop storing operation data when it determines that construction of a pile has ended.

[0049] The property identification display field P512 displays identification information (for example, the property number and the pile number) for identifying the pile currently being constructed. The identification information displayed in the property identification display field P512 allows the operator to confirm whether the pile number indicated in the pile setting drawing matches the pile currently being constructed.

[0050] In addition, the management device calculation unit 510 may accept an operation to specify the pile number of the construction target from the operator at the start of construction of the pile, and link it to the operation data of the pile. Furthermore, each pile has position information. That is, each pile has coordinate values ​​based on the grid shown in the pile setting plan of Fig. 4. Therefore, when the pile construction starts, if the coordinates (e.g., latitude and longitude) of the pile indicated in the pile setting plan match the coordinates (e.g., latitude and longitude) of the construction position by the construction machine 51, the management device calculation unit 510 may link the pile number of the pile indicated in the pile setting plan to the operation data of the pile.

[0051] The construction date and time display field P513 displays the construction timing of the pile (for example, the construction time or the construction date and time). As an example, the construction machine management device 500 has a clock function. The management device calculation unit 510 links the time information or date and time information obtained from the clock function when the construction of the pile starts to the operation data. In addition, the management device calculation unit 510 may link the time information or date and time information to the operation data each time the construction of the pile progresses (for example, each time the depth of the construction head becomes deeper by a predetermined depth).

[0052] That is, the operation data includes information indicating the construction time or construction date and time for each pile (ground improvement body).

[0053] The operation data display field P514 displays the state of the work performed by the work machine 51 (that is, the measured values ​​of the operating state of the operating parts of the work machine 51) in real time.

[0054] (Step S430) The on-site terminal device 400 acquires the operation data stored in the management device storage unit 520 of the construction machine management device 500. The operation data can be acquired not only by connecting the management device memory unit 520 and the field terminal device 400 (tablet, smartphone) with a wire, but also by transferring the operation data via a storage medium (e.g., USB (Universal Serial Bus) memory) or by short-range wireless communication such as Wifi (registered trademark) or Bluetooth (registered trademark).

[0055] In this case, the communication unit 211 (operation data acquisition unit) is capable of acquiring the operation data output by the construction machine 51 (construction machine) via a data recording medium or a communication line.

[0056] In addition, in the example of this embodiment shown in Figure 1, the construction machine management device 500 mounted on the construction machine 51 is located outside the functional configuration of the construction management system, but this is not limited to this, and the functions of the construction machine management device 500 may be included in the functional configuration of the construction management system. For example, by integrating the construction machine management device 500 of the construction machine 51 with the on-site terminal device 400, i.e., by equipping the construction machine 51 with the functions of the on-site terminal device 400, or vice versa, by equipping the on-site terminal device 400 with the functions of the construction machine management device 500, it is possible to transmit operation data of the construction machine to the server 200 via a long-distance wireless communication line. It is also possible to incorporate the functions of the construction machine management device 500 into the server 200 itself, and transmit operation data of the construction machines directly to the server 200 via a long-distance wireless communication line.

[0057] The on-site terminal device 400 can acquire the operation data at any timing from the management device storage unit 520. For example, when a plurality of piles are constructed on a certain property, the on-site terminal device 400 acquires the operation data stored in the management device storage unit 520 at the time when the construction of the first pile (or two or three piles) is completed. According to the construction management system 1 configured in this manner, the construction result can be determined earlier than the case where the construction result is determined based on the operation data after the construction of all piles on a certain property is completed.

[0058] (Step S440) The field terminal device 400 transmits report information to the server 200. This report information includes the operation data acquired in step S430. The on-site terminal device 400 can transmit the report information to the server 200 at any timing. For example, the on-site terminal device 400 transmits the report information to the server 200 on the condition that a transmission operation is performed by the user of the on-site terminal device 400. This transmission layer can also be said to be an instruction to the server 200 to start a determination operation. In this case, the function of accepting a transmission operation by the user and transmitting the report information to the server 200 is also called a determination instruction means.

[0059] That is, the construction management system 1 may have a judgment instruction means for causing the judgment unit 214 to output the judgment result at any timing during construction.

[0060] 14 is a diagram showing an example of the operation data selection screen P420 of this embodiment. The operation data selection screen P420 is a screen for selecting the operation data to be included in the report information and transmitted to the server 200 when the on-site terminal device 400 acquires operation data for a plurality of piles.

[0061] FIG. 4A shows an operation data selection screen P420-1 in which operation data for a plurality of piles (for example, seven piles) can be selected. FIG. 4B shows an operation data selection screen P420-2 in which operation data for a plurality of piles (eg, seven piles) is selected, and several piles (eg, three piles) are selected. Fig. 4C shows a confirmation screen (operation data selection screen P420-3) for transmitting operation data for several piles (e.g., three piles) selected in Fig. 4B to the server 200. Note that the "construction data" in "The selected construction data will be acquired and transmitted" on the confirmation screen refers to the operation data.

[0062] (Step S220) The communication unit 211 of the server 200 acquires the report information transmitted by the field terminal device 400. As described above, the report information includes operation data.

[0063] That is, the communication unit 211 acquires operation data based on the measurement values ​​of the operation state of the operation unit of the construction machine 51 (construction machine) for constructing soil improvement bodies, which are pillar bodies or foundation piles, in the ground. In other words, the communication unit 211 functions as an operation data acquisition unit.

[0064] As described above, the operation data may include identification information that identifies each of the multiple ground improvement bodies to be constructed on the property that is the target of construction.

[0065] In this case, the communication unit 211 (property-specific design specification data acquisition unit) acquires property-specific design specification data including multiple soil improvement bodies.

[0066] Moreover, the communication unit 211 (operation data acquisition unit) acquires at least operation data for each of a plurality of soil improvement bodies constructed on the property.

[0067] In addition, the communication unit 211 (operation data acquisition unit) is capable of acquiring operation data by comparing the position information of the ground improvement body based on the layout plan drawing of the ground improvement body with the position information of the construction position output by the construction machine 51 (construction machinery) or the computer at the construction site.

[0068] In addition, the communication unit 211 (operation data acquisition unit) is capable of acquiring property-specific specification data by comparing location information, for example, of the location of the construction site corresponding to the construction site where the ground improvement body is to be constructed, with location information output by the construction machine 51 (construction machinery) or the computer at the construction site.

[0069] The server computing unit 210 stores the acquired report information in the server storage unit 220. As a result, the report information and the operation data included in the report information can be viewed on the office terminal device 100, the manager terminal device 300, and the field terminal device 400. For example, the display unit of the office terminal device 100 can display the construction results for each pile.

[0070] 15 is a diagram showing an example of the pile-by-pile construction result display screen P130. The pile-by-pile construction result display screen P130 is an image that displays the construction result for each pile. It is also possible to display the construction results for each pile in a graph format.

[0071] 16 is a diagram showing an example of the pile-by-pile construction graph display screen P140. The pile-by-pile construction graph display screen P140 is an image that displays the construction results for each pile in a graph format.

[0072] (Step S230) The construction machine 51 may generate operation data in different formats depending on the manufacturer and model. For example, the units of operation data (e.g., units of the number of rotations of the rotation shaft), item names, and item order may differ depending on the manufacturer.

[0073] FIG. 17 is a diagram showing an example of the model-specific operation data D510. In this case, the server calculation unit 210 converts the model-specific operation data D510 into the standard format of the construction management system 1, and generates converted operation data D520. The information processing for conversion can be performed, for example, by referring to a correspondence table for correcting the units, item names, item order, etc. of the operation data for each manufacturer and model of the construction machine 51, as shown in FIG.

[0074] 18 is a diagram showing an example of converted operation data D520. This converted operation data D520 directly corresponds to the output of FIG. According to the construction management system 1 configured in this manner, even if the format of the operation data differs depending on the manufacturer or model of the construction machine 51, the construction management system 1 can convert the data into a format that can be used.

[0075] The server 200 acquires the report information transmitted by the on-site terminal device 400, stores the operation data D510 and the converted operation data D520, and starts the construction value calculation unit 213 and the judgment unit 214 to output the judgment result. That is, the server 200 performs the judgment calculation process after generating and storing the operation data in response to a transmission instruction from the on-site terminal device 400 at any timing during or after construction. However, this is not limited to this, and as another embodiment, a judgment instruction button (judgment support means) can be provided on the screen of the on-site terminal device 400 (other terminal or server). In this way, the storage of the operation data by the instruction of the transmission button and the execution of the judgment calculation process by the judgment instruction button can be performed at the required timing, respectively.

[0076] (Step S240) The testing means acquisition unit 212 acquires a testing means. The inspection means defines the construction standard for judging the construction result of the pile. In other words, the inspection items showing the quality of the construction and the corresponding inspection methods are defined as an inspection formula using, for example, a mathematical formula. The verification means is determined in advance for at least one of the types of the property to be constructed, or the construction method and specifications of the ground improvement body. The construction method for the ground improvement body is entered in the "Construction method type" field on the property information registration screen, for example, the grind column method (the name of the cement ground improvement method) or the EAZET method (the name of the steel pipe pile method).

[0077] That is, the inspection means acquisition unit 212 acquires an inspection means that defines an inspection method corresponding to an inspection item that is predetermined for at least one of the types of the specifications of the soil improvement body, the construction method, or the property to be constructed.

[0078] The verification means is information accessible to a computer and includes at least a description of the contents of the computation process. The embodiment may be in the form of a data file or a program description.

[0079] Here, the method of acquiring the test means can adopt various embodiments. That is, it is possible to refer to and use a plurality of items corresponding to the "construction method type" that are temporarily held or stored in the server or terminal device constituting this construction management system. As another form, it is also possible to access and use (by referring to via a communication line) a test means that exists outside the server of this construction management system. At this time, the inspection means acquisition unit 212 refers to the "construction method type" included in the property-specific design specification data D200, and selects an inspection means corresponding to the construction method type.

[0080] In addition, the testing means is a calculation process performed by the construction value calculation unit 213, which calculates the construction value using a testing method (test formula), and the judgment unit 214, which judges whether the construction value meets the testing standard or not, and various embodiments can be adopted for these. That is, the testing means, the construction value calculation unit 213, and the judgment unit 214 may each be configured separately, or all of them may be configured as an integrated unit. As an embodiment in the case of an integrated configuration, for example, it can be created as a single calculation processing execution file using the function function or macro function of spreadsheet software.

[0081] Here, the method of acquiring the testing means is to store it in the memory unit of the server and acquire it by accessing this memory unit, but if the testing means is present in another terminal device of this construction management system, or in a device outside this construction management system, it can be acquired via a communication line. That is, the testing means acquisition unit 212 can acquire the testing means from either a computer constituting the construction management system 1 or a computer outside the construction management system 1 via a communication line.

[0082] [Test items, test methods (test formula and test criteria)] 19 is a diagram showing an example of inspection items and inspection methods (inspection formulas). Inspection items are set for each construction method. Calibration formulas are classified into the following types depending on the data used for calculation. For example, there are types that include one operation data, which is data on construction results, as a variable (Type 1), types that include multiple operation data as variables (Type 2), and types that include operation data and property-specific design specification data as variables (Type 3). The calibration formula then quantifies whether the value (construction value) calculated using these variables meets the calibration value, which is the standard value for construction quality. When the property-specific design specification data itself is adopted as the calibration value, there are cases where a value that is guaranteed to ensure quality through experimental verification (a value that has been reviewed by a public technical certification body or technical authentication body (hereinafter referred to as the technical authentication body)) is adopted. Below, as an example, some of the inspection items when the grind column method (cement ground improvement method) is selected will be explained.

[0083] (Example of test item (1) Head milk discharge) "Head milk discharge" is a method for determining whether or not the discharge of cement milk during ground improvement work is started from the top of the ground improvement body to be constructed (column top) or above the top of the column. If discharge starts below the top of the column, cement milk is not being supplied to the pile head of the column. This is in compliance with the principle of "uniform discharge" described in the inspection certificate (quality standard) by the technical certification organization for the grind column method.

[0084] Here, the information that the server 200 obtains from the construction machine 51 is operation data of the construction machine 51. This operation data does not directly indicate whether or not the cement milk has started to be discharged from the top of the column. In addition, the top of the column is designed for each property in consideration of the ground improvement method and the embedment depth of the concrete foundation of the building to be constructed on the improved ground. Therefore, in order to determine whether the "head milk discharge" construction status is satisfactory or not, it is necessary to prepare in advance a test formula for testing whether or not cement milk has started to be discharged from the top of the column based on the operation data and property-specific design specification data. Here, the operation data of the construction machine 51 includes the depth of the construction head and the accumulated flow rate (accumulated discharge amount) of the cement milk as measurement values. The "depth of the construction head" is the value measured using a depth measuring device equipped on the construction machine 51 to measure the position (depth) that the construction head has excavated from the design GL (ground line). The "accumulated flow rate of cement milk" is the flow rate of cement milk discharged from the construction head per unit depth (e.g., 0.10 m), measured using a flow meter, and accumulated from the start of construction (the depth of the top of the column) to that depth. In addition, the design specification data for each property includes the "design embedment depth" and "DN amount" to derive the "column top". Therefore, the contents of the testing method and the testing formula are as follows: The inspection method defines that cement milk is being discharged from the top of the column or above the top if the cumulative discharge volume of cement milk increases when the depth of the construction head shown in the operation data changes from a position shallower than the top of the column (above) to a position deeper than the top of the column (below) (top-straddling state). This inspection method can be rephrased as the inspection standard for the inspection item. In line with this definition, specifically, "The cumulative discharge amount of cement milk at the depth of the top of the column (strictly speaking, from just above the top of the column to the top of the column) is A, When the cumulative discharge amount of cement milk at the depth directly below the top of the column is B, If the difference (BA) between the accumulated discharge amount A and the accumulated discharge amount B is positive (BA>0), the inspection criteria are met, and if it is 0 (BA=0, <0), the inspection criteria are not met. The above is expressed as a mathematical formula to set the equation for consideration. That is, BA>0 is set in the test formula. The value of BA on the left side of the test formula is the construction value calculated by the construction calculation unit. The value of 0 on the right side of the test formula is the test value. Here, the "column top end" is the part shown in FIG. 20, and the value of the "column top end" is calculated by the following formula.

[0085] "Column top" = absolute value of design GL (ground line) - ("design embedment depth" + "DN amount")

[0086] In FIG. 21, the "column top" is calculated to be at the design GL-0.405m+0m position. In addition, the cumulative discharge volumes A and B are calculated by using the "cumulative flow rate (discharge volume) of cement milk" at a "construction head depth" of 0.400 m, which approximately corresponds to the "column top" (design GL-0.405 m), and the same value at a "construction head depth" of 0.41 m, which corresponds to directly below the "column top". In case 1, based on the test method (test formula), the construction value calculation unit 213 calculates that the construction value (BA) is 3-2=1, and tests that the construction value is positive (>0) (i.e., a result that meets the test criteria is output). In response to this, the judgment unit 214 outputs "◯ (good)" as the judgment value. In case 2, based on the test method (test formula), the construction value calculation unit 213 calculates that the construction value (BA) is 0-0=0, and tests that the construction value is 0 (i.e., a result that does not satisfy the test criteria is output). In response to this, the judgment unit 214 outputs "x (bad)" as the judgment result. In this way, for the test item "head milk discharge", a test formula (Type 3) is set based on two types of measurement values ​​(i.e., "construction head depth" and "cement milk flow rate"), which are operation data, and "design embedment depth" and "DN amount", which are property-specific design specification data.

[0087] (Example of test item (2) Deepest milk discharge) The test item "deepest part milk discharge" is to determine whether or not cement milk is being discharged at the deepest part of the ground improvement body to be constructed (deepest part of the column) during ground improvement work. If discharge stops above the deepest part of the column, milk is not being supplied to the column from the discharge stop depth to the deepest part. This is to comply with the principle of "uniform discharge" described in the inspection certificate (quality standard) by the technical certification organization for the grind column method.

[0088] Here, the information that the server 200 obtains from the construction machine 51 is operation data of the construction machine 51. This operation data does not directly indicate whether or not the cement milk is being discharged at the deepest part. Therefore, it is necessary to prepare in advance a calibration formula for determining whether or not the cement milk is being discharged at the deepest part based on the operation data. Where: The operation data of the construction machine 51 includes the depth of the construction head and the amount of cement milk discharged as measurement values. Therefore, the contents of the testing method and the testing formula are as follows: The calibration method is defined as follows: if the cumulative discharge amount of cement milk increases while the depth of the construction head indicated by the operation data indicates the deepest part of the column, the cement milk is discharged at the deepest part. This calibration method can be rephrased as the calibration standard for the calibration item. In line with this definition, specifically, "If the cumulative discharge amount of cement milk at the depth just above the depth corresponding to the deepest part of the column is A, and the cumulative discharge amount of cement milk at the depth corresponding to the deepest part of the column is B, then if the difference (BA) between the cumulative discharge amount A and the cumulative discharge amount B is positive (BA>0), the inspection criterion is met, and if it is 0 (BA=0), the inspection criterion is not met." is formulated, and the examination equation is set. That is, BA>0 is set in the test formula. The value of BA on the left side of the test formula is the construction value calculated by the construction calculation unit. The value of 0 on the right side of the test formula is the test value. Here, the position of the "deepest part of the column" is the part shown in Figure 20 and is identified by the maximum value of the "depth of the construction head". In Figure 22, the cumulative discharge volumes A and B are the "cumulative flow (discharge volume) of cement milk" at a "depth of the construction head" of 3.51 m, which is directly above the "deepest part of the column," and the same value at a depth of 3.52 m, which is the depth of the "deepest part of the column." In case 1, based on the test method (test formula), the construction value calculation unit 213 calculates that the construction values ​​(B1-A, B2-A, B3-A) are 409-408=1, 410-408=2, and 411-408=3, and tests that all of the construction values ​​are positive (>0) (i.e., a result that meets the test criteria is output). In response to this, the judgment unit 214 outputs "◯ (good)" as the judgment value. In case 2, the construction value calculation unit 213 calculates that the construction values ​​(B1-A, B2-A, B3-A) are all 409-409=0 based on the test method (test formula), and tests that all the construction values ​​are 0 (i.e., a result that does not satisfy the test criteria is output). In response to this, the judgment unit 214 outputs "x (bad)" as the judgment result. In this way, for the test item “deepest part milk discharge”, a test formula (type 2) based on two types of measurement values ​​(i.e., “depth of construction head” and “cement milk flow rate”) is set.

[0089] (Example of test items (3) (total length) milk volume) The test item "(Total length) Milk volume" is used to determine whether or not the required amount of cement milk is discharged over the entire length of the excavation depth (for example, column length) during excavation. The amount of cement milk guarantees the design strength of the ground improvement body. This is an item to comply with the "Required amount discharge regulations" stated in the inspection certification (quality standards) by the technical certification body for the Grind Column Method and the principle of "Required cement addition amount discharge" according to the design documents. The milk volume refers to the total amount of cement milk discharged during excavation from the top of the column to the deepest part of the column.

[0090] 23 is a diagram showing an example of a process from the start of concrete pouring to the end of concrete pouring by the construction machine 51. The process from the start of concrete pouring to the end of concrete pouring by the construction machine 51 includes a process of digging to the full length of the excavation depth (the deepest part) (i.e., the outward trip) and a process of pulling up from the deepest part (i.e., the return trip). Here, when the amount of cement milk discharged in the entire process from the start of pouring by the construction machine 51 to the end of pouring is accumulated, the amount discharged on the return trip may be included. In this case, it becomes impossible to accurately determine whether or not the amount of cement milk (required accumulated flow rate) required to ensure construction quality is discharged over the entire length of the excavation depth (for example, column length) during excavation (i.e., on the outward trip).

[0091] Furthermore, even if the amount of cement milk discharged at a depth above the top of the column is accumulated, it will not be possible to accurately determine whether the required amount of cement milk is being discharged over the entire excavation depth (e.g., the column length).

[0092] Therefore, for the test item "(total length) milk volume", a test formula is set that calculates only the cement milk discharge volume during excavation (forward trip) at a depth below the "column top" (Type 3).

[0093] (Other examples of test items) In addition to the example mentioned above, other inspection items based on cement flow rate include, for example, "actual addition amount" and "bottom mixing for 20 seconds."

[0094] moreover, For the test item related to pile length, a test formula is set that stipulates that the "column length" (construction value), which is the value obtained by subtracting the "column top" from the maximum value of the "(construction head depth)," which is the operating data, is within the range (test value) between the "design column short length" and the "design column long length" in the property-specific design specification data (Type 3). For the construction speed test item, in order to ensure that the soil and cement milk are sufficiently mixed, a test formula is set that dictates that the value (construction value) obtained by dividing the operation data "depth of construction head" by the operation data "construction time" is equal to or less than a specified standard construction speed (test value) (Type 2). For the test item related to the number of revolutions of the rotating shaft, in order to ensure that the soil and cement milk are thoroughly mixed and stirred, a test formula is set that stipulates that the value (construction value) of the "number of times the blades are cut" multiplied by the "number of revolutions of the rotating shaft" (operation data) or the "number of blades" (property-specific design specification data) must be equal to or greater than a specified standard value (test value) (Type 1 or 3). For each of these test items, a test formula has been established so that the quality of the construction can be judged based on the measurement results of the operating parts of the construction machine 51, such as the depth of the construction head, the rotation speed of the rotating shaft, and the flow rate of cement milk (operational data measured by the construction machine), or design specification values ​​such as the number of blades (property-specific design specification data).

[0095] We will also explain the overview of the inspection items when EAZET piles (steel pipe pile method) are selected as the construction method for the ground improvement body. The test items include the following items related to pile length, bearing capacity and friction force of the pile, and the test procedures include the following test methods (test standards). Items related to pile length: pile top level, data continuity, actual pile length, etc. The calibration formula is set using the operating data, "construction head depth," and property-specific design specification data, "column length" and "design embedment depth." For items related to bearing capacity and frictional force, such as short-term torsional strength, length considering peripheral friction, and control torque value, the calibration formula uses mathematical expressions that use operating data such as "rotation speed of the rotating shaft" and "torque value of the rotating shaft," and property-specific design specification data such as "column diameter (pile diameter)," "wing diameter," "number of wings," "design long-term allowable bearing capacity of the pile," "whether or not the supporting ground layer is inclined," "short-term torsional strength," and "control torque value."

[0096] In addition, the operation data may include information indicating the construction time or construction date and time for each ground improvement body.

[0097] As described above, the operation data includes identification information that identifies each of the multiple ground improvement bodies to be constructed on the property that is the target of construction. In other words, it can be said that the test value acquisition unit 212 acquires at least the test means for the ground improvement body to be evaluated among a plurality of ground improvement bodies. For example, if the design specifications for a single property dictate the use of different construction methods (e.g., cement ground improvement method, steel pipe pile method) for each construction area, a testing means corresponding to each construction method type for that construction area can be obtained.

[0098] The server calculation unit 210 may also include a test item setting unit 215 that sets the above-mentioned test formula. The test item setting unit 215 sets test items for each specification of the ground improvement body, each construction method of the ground improvement body, or each property to be constructed.

[0099] Also, for example, the construction machine 51 (construction machine) may be one that constructs a ground improvement body by rotating a construction head by a rotating shaft to which a predetermined rotational torque is applied and pouring cement milk into the ground. In this case, the parameter of the calibration formula may be based on at least one of the depth of the construction head, the number of rotations of the rotating shaft, and the flow rate of cement milk. The construction machine 51 (construction machine) may be one that buries the ground improvement body in the ground by rotating the construction head with a rotating shaft to which a predetermined rotational torque is applied. In this case, the parameter of the calibration formula may be based on at least one of the depth of the construction head and the number of rotations of the rotating shaft.

[0100] (Step S250) The construction value calculation unit 213 calculates the construction value corresponding to the test item based on the operation data. Here, the construction value corresponding to the test item is a value obtained by applying the measurement value included in the operation data to the test formula set for each of the above-mentioned test items. For example, for the test item "head milk discharge", the construction value calculation unit 213 provides the construction head depth and the cumulative discharge amount of cement milk, which are the measured values ​​included in the operation data, to the test formula. As a result, the construction value calculation unit 213 calculates whether the cumulative discharge amount of cement milk is increasing in the crest straddling state.

[0101] That is, the construction value calculation unit 213 calculates a construction value corresponding to the test item based on the operation data acquired by the communication unit 211 (operation data acquisition unit) or the property-specific design specification data acquired by the communication unit 211 (property-specific design specification data acquisition unit) and the test method defined in the test means acquired by the test means acquisition unit 212.

[0102] Here, the testing method defined in the testing means may be composed of a testing formula based on any one or more of multiple types of measurement values ​​included in the operational data, or multiple types of design specification values ​​included in the property-specific design specification data.

[0103] In this case, the construction value calculation unit 213 calculates the construction value by a verification equation based on any one or more types of measurement values ​​among the multiple types of measurement values ​​included in the operation data D50.

[0104] As described above, the operation data includes identification information that identifies each of the multiple ground improvement bodies to be constructed on the property that is the construction target. In other words, it can be said that the construction value calculation unit 213 calculates at least the construction value of the ground improvement body to be evaluated among a plurality of ground improvement bodies. For example, if the design specifications for a single property dictate the use of different construction methods (e.g., cement ground improvement method, steel pipe pile method) for each construction area, the construction value of each pile is calculated using a calibration formula based on the calibration means obtained for each construction method type for that construction area.

[0105] (Step S260) The judgment unit 214 judges whether the construction quality of the ground improvement body is good or bad by inspecting the construction value calculated in step S250 based on the inspection means acquired in step S240. (Step S270) The determination unit 214 transmits the determination result to the office terminal device 100, the manager terminal device 300, and the field terminal device 400 via the communication unit 211.

[0106] That is, the judgment unit 214 judges whether the construction quality of the ground improvement body is good or bad by inspecting the construction values ​​based on the inspection method corresponding to the inspection items defined in the inspection means.

[0107] Furthermore, the judgment unit 214 can output a judgment result indicating whether the construction quality of the soil improvement body is good or bad.

[0108] As described above, the operation data includes identification information that identifies each of the multiple ground improvement bodies to be constructed on the property that is the target of construction. In other words, the judgment unit 214 can be said to output a judgment result indicating whether the construction quality of the ground improvement body is good or bad by testing the construction values ​​when the ground improvement body to be evaluated is constructed among multiple ground improvement bodies using a testing means for the ground improvement body to be evaluated.

[0109] In addition, in the above-mentioned step S440, the determination unit 214 outputs the determination result in response to the on-site terminal device 400 transmitting the report information to the server 200. That is, the on-site terminal device 400 transmitting the report information to the server 200 corresponds to a determination instruction means for the server 200. The determination instruction means may be a button image (for example, a send button) displayed on the on-site terminal device 400. In this case, it can be said that the determination operation in the server 200 is started by operating the button image on the on-site terminal device 400.

[0110] (Steps S130, S450, S510) The office terminal device 100, the field terminal device 400 and the construction machine management device 500 each display the determination result output from the server 200.

[0111] FIG. 24 is a diagram showing an example of the pile-by-pile judgment result display screen P150. The pile-by-pile judgment result display screen P150 shows the construction date, construction time, representative inspection items, operation data, construction values, inspection standards (inspection values), or judgment results showing the quality of construction for each property and each pile number. In this example, if the construction quality is good, "◯" is displayed for each pile number, and if the construction quality is poor, "×" is displayed for each pile number. In addition, by clicking on each of the button images displayed as "determination details," "operation," and "graph" for the detailed data in the right column, the judgment details in FIG. 24 (a list of the construction values, inspection values, and judgment results for each inspection item), the pile details in FIG. 15 (a list of operation data), and the construction graph in FIG. 16 can be output for each pile number.

[0112] As described above, in the construction management system 1, the on-site terminal device 400 can transmit operation data to the server 200 at any timing, and the server 200 can judge the quality of construction for each pile number. In addition, the server 200 makes the judgment instantly (that is, automatically) without the intervention of an operator or other human being. Therefore, in the construction management system 1 of this embodiment, the result of judging the quality of construction of piles that have already been constructed can be obtained soon after the start of construction on a certain property. Therefore, the construction quality can be judged earlier than when poor construction quality is found after all piles to be constructed on a certain property have been constructed, and delays in construction time and increases in construction costs can be reduced.

[0113] (Step S280) Server 200 updates the report information stored in server storage unit 220 based on the result of the determination in step S260.

[0114] (Step S140) The office terminal device 100 acquires the report information after being updated in step S280. The office terminal device 100 stores the acquired report information as a construction record of the property, or outputs it as a document to be presented to a customer (for example, an owner or resident of the property).

[0115] Depending on the circumstances, it may be determined in step S260 that the construction quality of the soil improvement body is not good (or is poor) (that is, the determination is NG). As an example of the grind column method described above, a case where the test item is "mixing at the bottom for 20 seconds" will be described. In this case, the test formula is a formula for testing whether "mixing is performed for 20 seconds near the deepest part of the concrete in order to thoroughly mix the cement and soil mass at the deepest part," and if the mixing time near the deepest part of the concrete is less than 20 seconds, the test standard is not met and it is judged as poor (×). If the mixing time near the deepest part of the concrete is increased to 20 seconds or more by re-construction (or additional construction), it is judged as good. In this case, if the total time of the mixing time from the initial construction and the mixing time from the re-construction (or additional construction) is 20 seconds or more, it may be judged as good (◯). In this way, by integrating the initial construction situation and the re-construction (or additional construction) situation, it may be judged as good overall.

[0116] 27 is a diagram showing an example of integration of operation data when the judgment result is bad. In the example shown in the figure, the operation data D510-1 of pile No. 11 is judged to be bad in the item "20-second mixing at the bottom." Here, the operation data D510-2 during additional construction is assigned identification information (e.g., pile No. 111) different from that of pile No. 11. Assume that the bottom mixing time indicated by the operation data D510-1 of pile No. 11 is 15 seconds, and the bottom mixing time indicated by the operation data D510-2 during additional construction of pile No. 11 (i.e., pile No. 111) is 10 seconds. In this case, the bottom mixing time for pile No. 11 is determined to be 25 seconds, which is the total time of the initial construction and the additional construction, and the pass / fail is judged. In this way, the judgment unit 214 may judge the quality of the construction based on the integrated operation data D510-3 obtained by integrating the operation data of the initial construction (e.g., operation data D510-1) and the operation data of the additional construction (e.g., operation data D510-2).

[0117] As another example, a case where the test item is the "number of times the blades are cut" will be described. In this example, the test formula is a mathematical expression of the test value "number of times the blades are cut, 1000 or more (e.g., evaluating the degree to which the blades of the mixing blades mix the soil mass underground by the number of rotations of the rotating shaft of the construction machine)," and if the number of times the blades are cut is less than 1000, it is judged as poor (X). If the number of times the blades are cut increases to 1000 or more by reapplication (or additional application), it is judged as good (O).

[0118] FIG. 28 is a diagram showing an example of operation data before integration when the judgment result is bad (x). In the example shown in the figure, the number of wing cuttings for pile No. 11 is 900, which does not meet the inspection method (inspection criteria) defined in the inspection means, and is therefore judged to be bad (x). In this case, additional construction is performed on pile No. 11 as re-construction to make up for the construction deficiency, and a new pile No. 111 is registered in the property registration information, and the operation data, construction value, and judgment result of the additional construction are recorded. In this embodiment, the number of wing cuttings for pile No. 111 (i.e., additional construction of pile No. 11) is 300. Here, in this system, the operation data of pile No. 111 (i.e., operation data of the additional construction) is integrated with pile No. 11 (i.e., operation data of the original construction).

[0119] Fig. 29 is a diagram showing an example of operation data after integration. In this figure, the number of times of cutting wings due to the initial construction and the number of times of cutting wings due to additional construction are added together and integrated as the operation data of pile No. 11. Since the number of times of cutting wings is 1000 or more for the operation data after integration (1200 times in this example), the judgment unit 214 judges it as good (◯).

[0120] In the pile-by-pile judgment result display screen P150 in FIG. 24, which is a different example of input and output, the above-mentioned integration instruction is given by checking the checkbox in the "Integration" column in the "Reconstruction" column in the left column for pile No. 111, which is the integrated data, and inputting pile No. "11" in the "Replacement / Integration Pile No." column. Here, if an instruction to judge is given again and the judgment unit 214 judges it to be good, the display in the pile No. "11" judgment column on the pile-by-pile judgment result display screen P150 will change from "x" indicating poor to "o" indicating good. On the other hand, pile No. "111" will display "-" indicating that it is not subject to judgment. As a result, the system recognizes that the construction values, test values, and judgment results using the operating data that combines pile No. 11 with pile No. 111 are those of the official pile No. 11 after re-construction. In addition, users of this system can be shown that the re-evaluation result obtained by integrating the operation data of pile No. "11" (i.e., the operation data of the initial construction) with the operation data of pile No. "111" (i.e., the operation data of the additional construction) is the official evaluation result of pile No. "11" that was correctly constructed.

[0121] In cases where the re-construction cannot be compensated for by the additional construction described above, i.e., where defects in the construction of the initially constructed pile affect the entire pile and it is necessary to start over from the beginning, the operation data, etc. are recorded in correspondence with pile No. 11 as well as pile No. 111, as described above. In this case, instead of all (one set) of operation data for pile No. 11 used in the initial judgment, all (one set) of operation data for pile No. 111 is used to make the judgment.

[0122] In the pile-by-pile judgment result display screen P150 in FIG. 25, a replacement instruction is given by checking the check box in the "Replace" column in the "Reconstruction" column in the left column for pile No. 111, which is the original data for replacement, and inputting pile No. "11" in the "Pile No." to be replaced / integrated" column. Here, a judgment instruction (re-judgment) is given again, and if the judgment unit 214 judges it to be good, a "◯" indicating good is displayed in the pile No. "111" judgment column on the pile-by-pile judgment result display screen P150. On the other hand, a "-" is displayed for pile No. "11", indicating that it is not subject to judgment. As a result, the system recognizes that the construction values, test values, and judgment results using the operating data of pile No. 111 are those of the official pile No. 11 after re-construction. In addition, users of this system can be shown that the judgment result based on the operation data of pile No. "11" (i.e., the operation data of the original construction) is not adopted, and the re-judgment using the operation data of pile No. "111" (i.e., the operation data of the re-construction) is the official judgment result of pile No. "11" that was correctly constructed.

[0123] In this way, in this system, instead of simply overwriting the data for pile No. 11, a new pile No. 111 is first registered in the property information (the new pile No. is added to the list of property-specific design specification data), and the operation data at the time of re-construction, the re-construction value which is the construction value calculated by the construction value calculation unit 213 based on the re-construction operation data, and the result of the re-evaluation in which the judgment unit 214 judged whether the construction was successful or not based on the re-construction value are recorded together with the operation data, construction value, and judgment result (operation data, etc.) of the original pile No. 11, and then the above integration or replacement is performed. This makes it possible to keep records from the situation at the construction site during the construction to the final construction results, making the construction process transparent and ensuring quality assurance that satisfies traceability.

[0124] In other words, for a ground improvement body that has been reconstructed among a plurality of ground improvement bodies, the judgment unit 214 may be configured to judge the quality of the construction based on the construction values ​​after reconstruction, and to replace the judgment result of the ground improvement body before reconstruction with the judgment result after reconstruction, and output the judgment result.

[0125] In addition, the judgment unit 214 may be configured to combine the first construction value, which is the construction value used for the judgment before re-construction, and the second construction value, which is the construction value calculated by the construction value calculation unit 213 at the time of re-construction, to judge the quality of the construction after re-construction.

[0126] In addition, the judgment unit 214 may replace the first construction value, which is the construction value used for the judgment before re-construction, with the second construction value, which is the construction value calculated by the construction value calculation unit 213 based on the operation data at the time of re-construction, to judge whether the construction quality after re-construction is good or bad.

[0127] The server memory unit 220 of the server 200 stores and updates property-specific design specification data, operation data or re-construction operation data, construction values ​​or re-construction values ​​which are construction values ​​calculated based on the re-construction operation data, or the results of judgment or re-evaluation in which the construction is judged to be satisfactory or unsatisfactory based on the re-construction values, in association with basic information of each property.

[0128] That is, the construction management system 1 may have a storage means (not shown). This storage means stores, in association with basic information of each property, property-specific design specification data, operation data, operation data for re-construction, construction values, re-construction values ​​which are construction values ​​calculated based on the operation data for re-construction, judgment results, or re-judgment results in which the quality of construction is judged based on the re-construction values.

[0129] The construction management system 1 configured in this way makes it possible to check the results of construction during the construction of a property (especially immediately after construction has started). Therefore, the construction management system 1 can reduce construction time and additional costs compared to when construction defects are discovered after construction of a property has been completed and construction is re-done.

[0130] In addition, records of the construction site conditions and results during construction can be kept, further improving traceability regarding construction quality.

[0131] Furthermore, with this type of construction management system 1, it is possible to realize remote construction management that enables the on-site construction status and results to be checked in real time from a remote location such as an office or another site, and at any time during or after construction.

[0132] In the description of this embodiment, the server 200 is described as having each of the functional units from the test value acquisition unit 212 to the test item setting unit 215, but this is not limited to this. Also, the construction management system 1 is described on the assumption that a plurality of computer devices, namely, the office terminal device 100, the server 200, the manager terminal device 300, and the field terminal device 400, are connected via a network N, but this is not limited to this. For example, each of the functional units from the test value acquisition unit 212 to the test item setting unit 215 may be provided in the field terminal device 400, or may be provided by dividing the functions between the field terminal device 400 and the manager terminal device 300. In other words, the configuration of the computer device of the construction management system 1 described above is just one example, and any device configuration may be used as long as it is possible to determine the construction results at any timing based on the operation data of the construction machine 51.

[0133] Furthermore, the embodiments of input and output in the office terminal device 100, the manager terminal device 300, and the field terminal device 400 are not limited to those described above. That is, each terminal device can perform its own input and output.

[0134] For example, it is possible to register property information not in the office terminal device 100 but in the manager terminal device 300 or the field terminal device 400. Also, instead of the field terminal device 400, the manager terminal device 300 or the office terminal device 100 can directly receive operation data from the construction machine, instruct a judgment, or output the judgment result.

[0135] Moreover, it is also possible to access the construction management system 1 from any terminal device outside the network configuration to perform these inputs and outputs.

[0136] Furthermore, a program for implementing the functions of any of the components in any of the above-described devices may be recorded on a computer-readable recording medium, and the program may be read into a computer system for execution. Note that the term "computer system" as used herein includes an operating system or hardware such as peripheral devices. Also, the term "computer-readable recording medium" may include a flexible disk, a magneto-optical disk, a ROM, a CD (Compact Disc)-ROM (Read-Only Memory), etc. The term "computer-readable recording medium" refers to a portable medium such as a portable only memory (PWM) or a storage device such as a hard disk built into a computer system. Furthermore, "computer-readable recording medium" also includes a device that holds a program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. The volatile memory may be, for example, a RAM (Random Access Memory). The recording medium may be, for example, a non-transitory recording medium.

[0137] The above-mentioned program may be transmitted from a computer system in which the program is stored in a storage device or the like to another computer system via a transmission medium, or by transmission waves in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has a function of transmitting information, such as a network such as the Internet or a communication line such as a telephone line. The above program may be for implementing some of the above functions. Furthermore, the above program may be a so-called differential file that can implement the above functions in combination with a program already recorded in the computer system. The differential file may be called a differential program.

[0138] In addition, the function of any of the components in any of the above-described devices may be realized by a processor. For example, each process in the embodiment may be realized by a processor that operates based on information such as a program and a computer-readable recording medium that stores information such as a program. Here, the processor may, for example, realize the functions of each unit with individual hardware, or may realize the functions of each unit with integrated hardware. For example, the processor may include hardware, and the hardware may include at least one of a circuit that processes digital signals and a circuit that processes analog signals. For example, the processor may be configured using one or more circuit devices mounted on a circuit board, or one or both of one or more circuit elements. An IC (Integrated Circuit) or the like may be used as the circuit device, and a resistor or a capacitor or the like may be used as the circuit element.

[0139] Here, the processor may be, for example, a CPU. However, the processor is not limited to a CPU, and various types of processors such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor) may be used. In addition, the processor may be, for example, an ASIC (Application Specific Integrated Circuit). The processor may be a hardware circuit such as an ASIC (Application Specific Integrated Circuit). The processor may be, for example, composed of multiple CPUs, or may be composed of a hardware circuit such as an ASIC. The processor may be, for example, composed of a combination of multiple CPUs and a hardware circuit such as an ASIC. The processor may include, for example, one or more of an amplifier circuit or a filter circuit that processes an analog signal.
