Description

  The present invention relates to a traceability management system and a traceability management system that manages identification information obtained by reading an identification mark attached to a material handled at a construction site with a terminal by a management server connected to the terminal via a communication network. It relates to the technical field of management methods.

  For example, materials used for the construction of plant facilities such as a fertilizer plant and a boiler plant are manufactured in advance in a factory and then transported to a construction site. The construction material transferred to the construction site is appropriately processed at the site and then installed on the construction. The construction materials used for the construction of plant facilities are very large in type and quantity, so the work contents of workers responsible for construction work tend to be complicated, and it is necessary to appropriately manage the work of workers. Is done. Further, as a recent trend, importance is attached to quality control of materials used for plant construction and traceability management until materials are finally incorporated into a building and used.

  As a construction site management system for responding to such a request, for example, Patent Document 1 discloses a technique for managing traceability of materials and installation equipment using an RF-ID in which identification information is recorded. ing. Further, in Patent Document 2, the progress of construction work is displayed so as to be visually recognizable by distinguishing and displaying a place where work has been completed and a place where work has not been completed on the design drawing. A work progress management support system that facilitates management of construction sites is disclosed.

  According to Patent Document 1, it is said that the progress of a construction site can be tracked based on the work content stored at a later date by storing the completed work content in the RF-ID sequentially and configuring it so that it can be read out as appropriate. Yes. However, since the work contents that have not been executed or the work contents that are currently being executed are not stored in the RF-ID, it is difficult to manage them. In particular, in construction work, materials used for construction and design contents are specified in advance as material information and design information, but work actually performed by workers in the past, work currently in progress, and future work It cannot be verified whether the content of the work to be performed is appropriate in light of these pieces of information. Therefore, it is difficult to prevent in advance even when inappropriate materials are used for construction work or when inappropriate work is performed. As described above, in the background art, there is a problem that materials and work contents used for construction work cannot be sufficiently managed. In particular, the construction materials used for the construction of plant facilities are very many in kind and quantity, and the work content is complicated, so that such a problem becomes even more remarkable.

  In addition, as a recent trend, even after construction is complete, if a defect is later discovered in a material manufactured at a factory (for example, if the material is subject to a recall), the target material can be quickly grasped. It is important to take measures. As described above, the demand for traceability is increasing year by year, and it is desired to secure more accurate and reliable traceability.

  The present invention has been made in view of the above problems, and an object thereof is to provide a traceability management system and a traceability management method capable of comprehensively managing material quality, traceability, and work contents at a construction site. .

  In order to solve the above problems, the traceability management system of the present invention includes identification information acquired by reading an identification mark attached to a material handled at a construction site with a terminal in a management server connected to the terminal. In the traceability management system for managing the traceability of the material by storing in the storage means, the terminal has position detection means for detecting position information at a timing of reading the identification information, and the identification information is The information is stored in the storage means in association with the detected position information.

  According to the traceability management system of the present invention, by reading the identification mark with the terminal, the identification information of the material and the position information can be stored in the storage means in association with each other. Can grasp. Therefore, even under conditions such as plant construction sites where the types and quantities of materials are large, by appropriately acquiring location information using terminals in each process of construction work, material management is performed appropriately and reliability is improved. High traceability can be secured.

  The terminal may be configured to be connectable to a management server installed at a remote location via a wireless or wired communication network, or configured to be directly connectable by moving the terminal to a management server installation location. It may be. That is, a terminal owned by a worker at a construction site may be connected by communication to a management server installed at a remote office, or a management server is installed at a terminal used by a worker at a construction site. The terminal may be directly connected to the management server when returning to the office or the like. In the former case, various types of information can be exchanged with the management server at any time via the communication network. In the latter case, various types of information can be exchanged with the management server when connected directly to the management server. It is good to do.

  The position detecting means is means capable of acquiring position information indicating where the terminal is located on the construction site of the terminal by receiving GPS signals and Wi-Fi signals. As another example of the position detecting means, for example, a means capable of reading a position identification bar code or a position identification IC tag provided in advance for each position section of the construction site may be adopted.

  As one aspect of the present invention, the management server further includes a material information database that stores material information that defines materials necessary for construction work, and the terminal receives the read identification information from the material information database. By comparing with the acquired material information, it is preferable to verify whether or not the material with the identification mark attached matches the material specified in the material information, and store the verification result in the storage means. In this case, it is possible to determine whether or not the construction material is an appropriate material defined in the material information by collating the material information defined in advance with the identification information acquired from the terminal. Therefore, it is possible to prevent an erroneous construction material from being used for construction, and to perform advanced quality control of the construction material.

  The management server further includes a design information database that stores design information that defines the design content of the building, and the terminal compares the read identification information with the design information acquired from the design information database. Thus, it may be verified whether or not the material to which the identification mark is attached matches the design content defined in the design information, and the result of the verification may be stored in the storage means. In this case, it can be determined whether or not the material is suitable for the design content defined in the design information. Therefore, when an operator tries to use an incorrect material that does not match the design information in the work process, the error can be detected in advance by collation with the design information. As a result, it becomes possible to realize advanced management of the work contents of the worker.

  Preferably, every time the terminal acquires the identification information, the terminal detects the position information by the position detection unit, and updates the position information stored in the storage unit. In this case, since the position information can be updated to the latest state every time the identification mark is read and operated on the terminal, the existence position of the material can be traced more accurately. As a result, when searching for a construction material on the construction site, it is possible to easily search based on the position information, and it is possible to construct a more accurate traceability.

  The management server further includes a worker information database that stores worker information for defining workers involved in construction work, and the terminal reads the worker identification mark owned by the worker and reads the worker information database. The content may be collated with worker information acquired from the worker information database, and the collation result may be stored in the storage means. In this case, since the operator who operates the terminal can be collated based on the worker information stored in the worker information database, it is possible to prevent an unsuitable worker from performing work. For example, it is possible to prohibit work by an unqualified worker during work that can only be performed by a worker having a specific qualification, such as welding work.

  The management server further includes a welding member information database for storing welding member information defining welding members engaged in construction work, and the terminal reads a welding member identification mark owned by the welding member, The content may be collated with the welding member information acquired from the welding member information database, and the collation result may be stored in the storage means. In this case, by reading the recorded content of the welding member sign at the terminal, the welding member used for the welding operation is collated with the welding member information acquired from the welding member information database, and the operator performs an incorrect welding during the welding operation. It is possible to prevent the use of materials and welding rods, and to ensure good work quality.

  Further, when a construction member that is installed in a construction by combining a plurality of the materials is newly created, the terminal associates the created construction member with identification information of each of the combined materials, and the storage unit You may register with. In a construction site, a new construction member may be created by combining a plurality of materials received from a manufacturing factory. For example, when the incoming material is piping, a spool may be manufactured by combining them. The newly created construction member can also be managed in the same manner as the above materials by adding the identification information and registering it in the database.

  The management server further includes a peripheral map database for storing the peripheral map information of the construction site, and the terminal includes the positional information stored in the storage means and the peripheral map information acquired from the peripheral map database. Based on this, the location of the material may be displayed on a surrounding map. In this case, the location of the material in each process can be visually displayed on the surrounding map. As a result, when searching for materials on the construction site, it is possible to easily search based on the position information, and it is possible to easily track where the materials are, which contributes to improving the work efficiency of workers. be able to.

  In addition, the terminal may include an imaging unit for acquiring a captured image, and the acquired captured image may be stored in the storage unit in association with the acquired identification information. In this case, since the appearance of the material can be stored in the storage means as a captured image, the operator can easily search for the material at the construction site by referring to the captured image or use the wrong material when handling the material. This can be prevented in advance. Thus, the work efficiency of workers and the quality control of materials can be improved effectively.

  The terminal may distinguish and display each of the materials in accordance with the progress of the installation work on the building. In this case, since the progress of the work can be visually grasped, the progress of the construction work can be easily managed.

  The identification information may include a production lot number of the material, and the terminal may display the material having the designated production lot number separately from other materials. In this case, when a failure is detected in a predetermined production lot number after construction, it is possible to easily grasp which part of the construction is incorporated, and it is possible to construct highly reliable traceability.

In order to solve the above-described problem, the traceability management method of the present invention is connected to the terminal through the communication network for the identification information acquired by reading the identification mark attached to the material handled at the construction site with the terminal. In the traceability management method for managing the traceability of the material by storing it in the storage means provided in the management server, the position detection means detects the position information at the timing of reading the identification information by the position detection means of the terminal And a storage step of storing the identification information in association with the detected position information in the storage means.
According to the traceability management method of the present invention, the above-described traceability management system (including the various aspects described above) can be suitably realized.

  According to the present invention, since the identification information and the position information of the material can be associated with each other and stored in the storage means by reading the identification mark with the terminal, it is possible to accurately grasp where the material is located. it can. Therefore, even under conditions such as plant construction sites where the types and quantities of materials are large, by appropriately acquiring location information using terminals in each process of construction work, material management is performed appropriately and reliability is improved. High traceability can be secured.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention unless otherwise specified, but are merely illustrative examples. Not too much.

  In the present embodiment, for example, in a series of construction work until the material manufactured at the factory arrives at the construction site of a plant facility such as a fertilizer plant or a boiler plant, and a spool is formed from the material to be installed on a construction object. A management system for managing the quality of materials and work contents will be described as an example.

  FIG. 1 is a block diagram showing the overall configuration of a management system 1 according to the present invention, and FIG. 2 is a schematic diagram conceptually showing the operation of a terminal used in the management system 1 according to the present invention. The management system 1 according to the present invention includes a terminal 100 owned by a worker and a server 300 that can communicate with the terminal 100 via a wireless communication network 200 (Internet).

  The terminal 100 includes a communication unit 101 for connecting to the wireless communication network 200, a barcode reading unit 102 for reading various barcodes, an ID card reading unit 103 for reading an ID card owned by an operator, and the terminal 100. Position detecting means 104 that can detect the position of the device based on a position signal (GPS signal, Wi-Fi signal, etc.) acquired from the outside, an input means such as a keyboard, mouse, or touch panel for an operator to input various information 105, a display unit 106 such as a display for displaying various types of information on a screen, a storage unit 107 for storing various types of information, and an imaging unit 108 for capturing an image.

  As shown in FIG. 2, a bar code 11, which is an identification mark in which identification information of the material 10 is recorded, is attached to the material 10 handled at the construction site, and the bar code 11 is attached to the terminal 100 (bar code reading). By reading with the means 102), the terminal 100 can acquire the identification information of the material 10. In addition, the worker who performs the work on the construction site uses the ID card 20 in which the worker identification information for identifying himself / herself (for example, personal information such as name and age, title, presence / absence and type of possession) is recorded. The terminal 100 can acquire worker identification information by reading the ID card 20 by the ID card reading means 103 of the terminal 100. Further, the position detection means 104 of the terminal 100 receives the GPS signals transmitted from a plurality of GPS communication satellites, or receives the wireless signals transmitted from the wireless LAN base station, thereby detecting the position of the terminal 100. Can be acquired as position information.

  The position acquisition means acquires position information from the GPS communication satellite when the terminal 100 is in a position where GPS signals can be received such as outdoors, and the terminal 100 is in a position where GPS signals cannot be received such as indoors. In this case, the position information may be acquired from the wireless LAN.

  Here, FIG. 3 is a flowchart showing the basic operation of the terminal 100. First, the worker who owns the terminal 100 operates the input means 105 to select the work content to be performed (material arrival, delivery, movement, installation, welding, etc.) (step S11). Subsequently, the terminal 100 is used to read the ID card 20 owned by the terminal 100 and the barcode 11 attached to the material 10 used for the work (step S12). As a result, it is acquired who is performing the work and what materials are used for the work.

  Subsequently, the terminal 100 acquires corresponding information from the appropriate database on the server 300 side via the wireless communication network 200 (step S13), and collates with the information acquired in step S12 (step S14). And when the collation result in step S14 is appropriate (step S14: YES), the terminal 100 emits a ping-pong sound and gives work permission to the worker (step S15), and the worker performs the corresponding work. (Step S16). The above collation result and work history are recorded on the server 300 side (step S17), and the quality of the material and the work content are managed by the server 300. In addition, when the collation result in step S14 is inappropriate (step S14: NO), the terminal 100 emits a warning sound (step S18), and prompts the worker to reconfirm the materials and work contents handled. (Step S19).

  Returning to FIG. 1 again, the server 300 has received a communication means 301 for connecting to the wireless communication network 200, a material information database 302 for storing material information, a design information database 303 for storing design information, and a construction site. Material receipt / shipment collation database 304 for storing the collation result of material 10, local progress management database 305 for storing progress information such as creation of spools using material, and local history for storing work contents performed by workers as history A database 306, a map information database 307 for storing map information around the construction site (such as a material storage area and a temporary storage area), and an ID worker database 308 for storing identification information of workers engaged in the construction work are provided. These various databases can be written by the terminal 100, and function as an example of the “storage means” of the present invention at this time.

  The material information stored in the material information database 302 includes information related to materials necessary for construction work, for example, material type, quantity, size, material, and the like. The design information stored in the design information database 303 includes information related to the design contents of the building, for example, piping lines in the case of piping work, pipe allocation information for specifying the pipe dividing method in the piping lines, The welding point information (such as the position and number of welding points) for specifying the welding method between the pipes is included.

  The material receipt / shipment collation database 304 reads the barcode 11 attached to the material 20 received at the construction site by the terminal 100 as described above, thereby collating the recorded contents of the barcode 11 with the material information. Is stored. A method for collating incoming materials using the terminal 100 will be described in detail later.

  The local progress management database 305 stores progress information such as the creation of spools using materials, and the local history database 306 stores the contents of work performed by workers on the construction site as a history. Here, FIG. 4 is an example of the local work history information related to the work history stored in the local history database 306. The local history information includes the time and place at which the work was performed, the content of the barcode or ID card read by the terminal 100, and the content of the work performed by the worker. These various items are recorded by reading the barcode 11 attached to the material 10 by the terminal 100, the ID card 20 owned by the operator, or the like.

  Next, specific operations of the management system 1 according to the present invention will be described in detail along the flow of actual construction work. A series of operations of the management system 1 can be classified into an incoming / outgoing management support operation, a local construction area position search operation, a work traceability / collation support operation, and a work progress visualization operation, which will be described in the following order.

  First, with reference to FIG. 5, the receipt / delivery management support operation of the management system according to the present invention will be described. FIG. 5 is a flowchart showing the specific contents of the receipt / delivery management support operation of the management system according to the present invention.

  First, when the material 10 arrives at the construction site from the manufacturing factory, the operator reads the barcode 11 attached to the material 10 received at the terminal 100 (step S101). Then, the terminal 100 automatically acquires material information corresponding to the content of the read barcode 11 by accessing the material information database 302 (step S102).

  Whether or not the material 10 necessary for construction is received in accordance with the order contents (that is, material information) by collating the recorded content of the barcode read in step S101 with the material information acquired in step S102. The collation result is recorded in the material receipt / shipment collation database 304 (step S103). This makes it possible to check whether or not the received material 10 is appropriate, so that an erroneous material can be prevented from being used for construction, and the quality of the material can be managed. Further, by storing the collation result as a history in the material receipt / shipment collation database 304, accurate traceability can be constructed.

  The material 10 for which the collation is completed is moved to the material storage by the worker. The bar code 11 is read again by the terminal 100 at the destination material yard for the material 10 moved by the worker (step S104). Then, the terminal 100 automatically receives a GPS signal transmitted from the GPS communication satellite 30 and acquires position information (step S105). The acquired position information is recorded in association with the collation result recorded in the material arrival collation database 304 in step S103 (step S106). Thereby, it is possible to manage on the server 300 side where the verified material has been moved after the arrival.

  The material 10 moved to the material storage is paid out at a timing required for the construction work. At this time, the worker uses the terminal 100 to search where the necessary material 10 is stored in the material storage area. The worker specifies the material 10 to be searched from the input means 105 of the terminal 100, whereby the location information of the material 10 from the material receipt / shipment collation database 304 (that is, the location information linked and recorded in step S106). ) Is acquired (step S107). Subsequently, the terminal 100 acquires the map information of the material storage area from the map information database 307 (step S108), and displays the point corresponding to the position information acquired in step S107 on the map (step S109). Such a display is made on the display means 106 of the terminal 100, and the worker easily recognizes where the material 10 to be searched is stored in the material storage area according to the displayed map. be able to. Thereby, the paying-out operation | work of the material 10 from a material storage place can be performed rapidly.

  FIG. 6 is a plan view schematically showing a material place where the material 10 after arrival is moved. Since the material storage area used at the time of plant construction has a very large area, it is divided into a matrix and managed as shown in FIG. 6, for example. For example, the position information may be information that allows the terminal 100 to specify in which plane of the matrix the terminal 100 is in a plane.

  Thus, the material 10 paid out by the incoming / outgoing management support operation is moved to the prefab factory. In the prefab factory, the spool 50 is manufactured by combining a plurality of materials 10 by an operator. FIG. 7 is a schematic view schematically showing a process of manufacturing the spool 50 from a plurality of materials.

  The material 10 paid out from the material storage area includes various shapes, sizes, weights, and materials such as a straight type, a T-shape, and an elbow type, and workers combine these materials. Thus, the spool 50 for installation on the construction is manufactured. In this system, in order to manage the new spool 50 manufactured from the existing material 10 by the worker in this way, the spool identification bar code 51 is attached. As a result, the spool 50 newly manufactured in the course of the construction work can be managed on the server 300 side.

  The spool 50 to which the spool identification bar code 51 is attached in this way is managed by being registered in the local progress management database 305. FIG. 8 is a flowchart showing a procedure for registering a newly manufactured spool 50.

  First, as described above, the spool identification barcode 51 is attached to the newly manufactured spool 50 (step S21). Thereafter, the spool identification bar code 51 is read by the terminal 100 (step S22). Subsequently, the barcodes 11 displayed on the plurality of materials 10 (materials managed in the material information database) used when manufacturing the spool 50 are read (step S23). Thereby, it can be associated with which material 10 the spool 50 is manufactured.

  Subsequently, the worker reads the ID card 20 owned by himself / herself at the terminal 100, and acquires who is the worker who performed the manufacturing work of the spool 50 (step S24). Then, the terminal 100 automatically acquires position information and recognizes where the work has been performed (step S25). Further, the operator picks up the manufactured spool 50 with the image pickup means 108, thereby acquiring the appearance of the spool 50 as an image (step S26). The spool barcode 51 read by the terminal 100 and the barcode 11 of each material 10 that is the raw material, the worker's ID card 20, the position information, and the photographed image are linked to each other in the local progress management database. Registered in 305 (step S27).

  FIG. 9 is an example of registration information of the spool 50 stored in the local progress management database 305. The section and line number of the construction in which the spool 50 is installed, the spool identification number automatically given by the terminal 100, the spool identification barcode 51, and the registration automatically acquired when the registration work is performed by the terminal 100 The date and time, the worker identification information (registrant ID) read from the ID card 20 of the worker who performed the registration work, and the read contents of the barcode 11 of each material 10 that has become the material are linked to each other and spool management table Stored as Thereby, it is possible to manage on the database which material 10 the spool 50 is manufactured from. Further, the position information automatically acquired from the GPS communication satellite 30 or the Wi-Fi 40, the registration date and time, the registrant ID, and the captured image file acquired from the imaging means are associated with each other and stored as a spool position information management table. Thereby, the position where the spool 50 is stored can be managed on the database.

  Next, with reference to FIG. 10, the specific content of the location search operation in the local construction area of the management system according to the present invention will be described. FIG. 10 is a flowchart showing the specific contents of the position search operation in the local construction area of the management system according to the present invention.

  As described above, the manufactured spool 50 is registered in the local progress management database 305 (step S201). When the worker reads the spool identification barcode 51 using the terminal 100, the terminal 100 automatically acquires design information from the design information database 303 (step S202). Then, the spool identification bar code 51 read in step S201 is collated with the design information acquired in step S202, and the collation result is recorded in the local history database 306 (step S23). Thereby, it is possible to determine whether or not the registered spool 50 is appropriately manufactured according to the design information, and it is possible to ensure the quality of the manufactured spool 50.

  Subsequently, the collated spool 50 is moved to a temporary storage location that is a storage location. The spool 50 that has been moved to the temporary storage place by the worker is read again by the terminal 100 at the temporary storage place of the movement destination (step S204). Then, the terminal 100 acquires position information by receiving a GPS signal transmitted from a GPS communication satellite (step S205). The acquired position information is recorded in association with the collation result recorded in the local history database 306 in step S203 (step S206). As a result, the server 300 can manage where the manufactured spool 50 has been moved in the temporary storage area.

  FIG. 11 is a plan view schematically showing a temporary storage place where the spool 50 is stored. Since the temporary storage used for the construction of the plant has a very large area, it is divided into a matrix and managed as shown in FIG. 11, for example. For example, the position information may be information that allows the terminal 100 to specify in which plane of the matrix the terminal 100 is in a plane.

  More preferably, when the position information is recorded, the location where the spool 50 is placed together with the position information is captured as image information from the imaging means 108, and the captured image information is linked to the position information in the local history database 306. Record it. As a result, when the worker searches for the storage location of the specific spool 50 in the temporary storage site, the corresponding image information is extracted from the local history database 306 and displayed on the display means 106, which is required for searching the storage location. The burden can be reduced.

  Next, with reference to FIG. 12, the operation traceability / collation support operation of the management system according to the present invention will be described. FIG. 12 is a flowchart showing the specific contents of the work traceability / collation support operation of the management system according to the present invention.

  Subsequently, when the operator installs the spool 50 on the construction, the operator makes a setup plan to determine which section and line are to be used with which spool 50 before the work. At this time, the terminal 100 acquires design information from the design information database 303, specifies the spool 50 necessary for the work based on the planned setup plan, and displays a list (hereinafter referred to as “part list” as appropriate). Create and display (step S301).

  The worker selects the spool 50 to be used for the work from the parts list displayed on the terminal 100 and accesses the local progress management database 305, so that the position information of the spool 50 (that is, the position of the temporary storage location of the spool 50). (Step S302), the terminal 100 acquires the map information of the temporary storage place from the map information database 307 (step S303), and corresponds to the position information acquired in step S302. The point is displayed on the map (step S304). As a result, the worker can easily recognize where the intended spool 50 is stored in the temporary storage place according to the map displayed on the terminal 100, and can search the spool 50 in the temporary storage place. Can be done quickly.

  Subsequently, the worker who has arrived at the spool 50 required in the temporary storage area reads the ID card 20 owned by the operator with the terminal 100 (step S305). The terminal 100 acquires worker information corresponding to the read contents of the ID card 20 from the worker database 308 (step S306), and collates whether the condition for the worker to perform the work is satisfied (step S307). For example, when the work is a welding work, whether or not the worker is a qualified welder is verified by comparing the read contents of the ID card 20 with the worker information. Thereby, the case where an unsuitable worker performs work can be prevented beforehand.

  Subsequently, the operator reads the spool identification bar code 51 attached to the spool 50 using the terminal 100 (step S308), and acquires design information corresponding to the spool 50 from the design information database 303 (step S309). ). The terminal 100 collates the spool identification barcode 51 with the design information to collate whether or not the spool 50 matches the design information, and records the collation result in the local history database 306 (step S310). ). As a result, it is possible to prevent an erroneous spool 50 from being used when installing the spool 50 on a construction object, and to record a work record in the local history database 306.

  Subsequently, the worker performs a welding operation in order to install the collated spool 50 on the construction. At this time, the operator uses the terminal 100 to check whether the material and welding rod used for the welding operation are appropriate. In the welding material and welding rod used in the present embodiment, identification information (various information indicating the specifications of the welding material and welding rod) is recorded in advance as a barcode as a welding member identification mark. Are compared with the welding member information corresponding to the welding material and the welding rod acquired from the welding member information database 309. The collation result is recorded in the local history database 306. As a result, it is possible to prevent the operator from using an incorrect welding material or welding rod during welding work, and to record the work record in the local history database 306.

  Here, FIG. 13 is an example of history information recorded in the local history database 306. In FIG. 13 (a), the collation result regarding the welding material is recorded. As specific items, the base metal, the welding method, the first layer brand, the last layer brand, the preheating temperature, the welding of the first layer and the last layer are recorded. There is a completion date, an appearance inspection date, and a P company appearance inspection date. In FIG. 13B, the collation result regarding the welding rod is recorded. As specific items, the weight of the welding rod, the amount of molten metal, the weight of the molten amount of gross, the date of dispensing, the payer is there.

  Next, the visualization operation of the management system according to the present invention will be described with reference to FIG. FIG. 14 is a flowchart showing the visualization operation of the management system according to the present invention.

  First, the terminal 100 obtains history information from the local history database 306, thereby grasping which part of the construction has been completed (step S401). Then, the terminal 100 acquires 3D data of the building from the design information database 303 (Step S402). Here, the 3D data of the building is, for example, a transparent view of the predicted completion of the building, and is displayed on the 3D data in different colors according to the degree of progress (step S403).

  FIG. 15 is a screen (display unit 106) of the terminal 100 that is color-coded on the 3D data according to the degree of progress. In the example of FIG. 15, the completed spool 50a is displayed on the 3D completion predicted view of the construction by coloring (displayed by hatching in this application), so that the work is distinguished from the unfinished spools 50b and 50c. Yes. As a result, the worker can easily visually recognize the progress status of the current construction work for a large-scale and complicated construction such as a plant.

  In addition, after the construction work is completed, there may be a case where a defect is later detected in the material 10 used for construction, such as a recall. In such a case, a defective lot number is notified from the manufacturer of the material 10. When the defective lot number is input from the input unit 105 of the terminal 100 (step S404), the terminal 100 searches the material information matching result recorded in the material information database 302 for the material 10 corresponding to the defective lot number. Identify. Then, the location where the material 10 corresponding to the specified defective lot number is installed is displayed on the 3D data. Here, FIG. 16 is a screen of the display means showing an example of the material corresponding to the defective lot number displayed on the 3D data. In the example of FIG. 16, the material or spool corresponding to the defective lot number is colored and displayed separately from other materials or spools. In this way, the worker can easily specify the location where the material 10 corresponding to the defective lot number is installed even in a large and complex construction such as a plant. Therefore, it is possible to quickly and accurately respond to the traceability request after construction.
