Description

[Technical field]

[0001] The present invention relates to a construction work support system for supporting construction work related to a construction project. [Background technology]

[0002] As the above construction work support system, for example, in a new construction project for constructing a new building, a design support device has been proposed that supports the design work of designing rooms of a new building that is the design target (for example, see Patent Document 1).

[0003] The design support device described in Patent Document 1 obtains performance information that combines the use of a previous building (a building whose design has already been completed), the use of the rooms in the previous building, and the design conditions of the rooms in the previous building; from that performance information, it extracts design conditions that correspond to the use of the building to be designed and the use of the rooms in the building to be designed; and outputs the extracted design conditions to be displayed on the display unit as the design conditions for the rooms in the building to be designed.

[0004] The user, that is, an architectural designer, can determine the design conditions for the rooms in the building to be designed while referring to the design conditions displayed on the display unit, thereby enabling the design work to be carried out more efficiently than if the design work were to be done from scratch.

[0005] [Patent Document 1] Patent No. 7077512 Summary of the Invention [Problem to be solved by the invention]

[0006] In the business practice of the construction industry, when executing a new construction project, it is common to divide the construction life cycle into multiple parts on a time axis and manage the construction project by dividing the work into phases. Here, the "construction life cycle" can be defined as the period from the moment the intention to build a building arises to the moment the building is destroyed, and the construction life cycle is divided into multiple phases, such as the "planning and development period," "basic planning period," "basic design period," "detailed design period," "construction preparation period," "construction period," and "facility maintenance and management period."

[0007] In this way, when the multiple phases divided in the construction life cycle are sequentially progressed, a large number of diverse construction tasks occur in each of the multiple phases. For example, there are construction tasks that include human decision-making. The construction tasks that include this decision-making include the design tasks described in Patent Document 1, but there are many other construction tasks as well. For example, in the early stages of phases such as the "planning and development period" and "basic planning period" of a construction project, there are construction tasks such as deciding the design of the building and calculating the construction budget. In phases such as the "detailed design period," there are construction tasks such as deciding the materials, specifications, quantities, etc. of each part that constitutes the building. In phases such as the "construction period," there are construction tasks such as deciding the type of construction method.

[0008] In construction work, including decision-making, a wide variety of conditions, such as customer requests and building conditions, must be considered, and a selection must be made from a wide variety of options, making the work complex and difficult. Although Patent Document 1 can effectively support design work, when viewed throughout the construction life cycle, it can only support a very small portion of the construction work, and there is a demand for support for many more construction works.

[0009] In addition, when progressing through multiple divided phases in a construction life cycle, not only construction work including decision-making arise but also many other types of construction work, which are also time-consuming, so there is a demand for support for these construction work as well.

[0010] In view of this situation, the main objective of the present invention is to provide a construction work support system that can support construction work and improve work efficiency throughout the entire construction lifecycle, which has multiple phases divided on a time axis, when advancing a new construction project. [Means for solving the problem]

[0011] A first characteristic configuration of the present invention is a construction work support system for supporting construction work related to a construction project, A construction work support device is provided that can execute a construction work support process that supports construction work by using project performance information acquired when a past construction project was carried out. When proceeding with a new construction project, the construction work support device is configured to be able to execute construction work support processing that supports construction work throughout the entire construction lifecycle having multiple phases divided on a time axis.

[0012] According to this configuration, the construction work support device can execute a construction work support process that supports construction work throughout a construction life cycle having multiple phases, so that when construction work is performed throughout the entire construction life cycle, the construction work can be supported using project performance information. As a result, when proceeding with a new construction project, construction work can be supported throughout the entire construction life cycle having multiple phases divided on a time axis, thereby improving work efficiency.

[0013] A second characteristic configuration of the present invention is that the construction work support device a project database creation unit that performs a project database creation process to create a project database for a construction project; a project execution unit that performs a project execution database creation process using the project database created by the project database creation unit as input data, and performs calculations on the project database to create a project execution database required for executing a project; a database group for storing a database including information necessary for creating a project database in the project database creation unit and for creating a project execution database in the project execution unit; a database analysis unit that accumulates the project database created by the project database creation unit and the project execution database created by the project execution unit, and performs data analysis processing of the accumulated databases; an information linking unit that links each unit by transmitting and receiving information between the project database creation unit, the project execution unit, the database group, and the database analysis unit, the information linking unit is configured to execute an analysis result storage process of sending analysis result information obtained by the database analysis process by the database analysis unit to the database group and storing the analysis result information in an analysis result information database related to the analysis result information; When construction work has been performed in a past construction project, the construction work support device performs a project database creation process by the project database creation unit, a project execution database creation process by the project execution unit, a data analysis process by the database analysis unit, and an analysis result storage process by the information linkage unit, thereby acquiring the created project database, the created project execution database, and an analysis result information database stored in the database group as the project performance information, When construction work is carried out for a new construction project, the construction work support device is configured to execute, as the construction work support process, a first regression process in which the information linking unit sends analysis result information accumulated in the analysis result information database from the database group to the project database creation unit and regresses the analysis result information, and the project database creation unit is configured to execute a first support process in which it uses the analysis result information to perform a project database creation process to create a project database.

[0014] According to this configuration, when construction work was performed in a past construction project, the project database creation unit performs a project database creation process, and the project execution unit performs a project execution database creation process, so that the database analysis unit can accumulate a project database and a project execution database corresponding to the past construction project. Here, for example, the project database is a collection of data that describes the materials and equipment required for construction, the structural materials and their specifications and quantities, etc., based on the functions and areas of the facilities that make up a building, by a method such as by part, and is linked to a BIM model, which is a collection of the layout, shape, and position of facilities and materials, to function as a substitute for conventional design documents, and the project execution database is a calculation document, etc., required to execute a project.

[0015] The Database Analysis Department performs data analysis processing, and the Information Linkage Department performs analysis result accumulation processing. The experience and know-how that has been accumulated by individuals involved in the project up until now is extracted as analysis result information as insight data from the accumulated project database and project execution database, and the analysis result information database regarding that analysis result information is accumulated in a group of databases.

[0016] In this way, when construction work has been carried out on a past construction project, the project database and project execution database corresponding to that past construction project are accumulated in the database analysis section, and the analysis result information obtained from that past construction project as insight data is accumulated in the analysis result information database of the database group.

[0017] When performing construction work to create a project database for a new construction project, the construction work support device performs a first support process in which the information linking unit performs a first regression process and the project database creation unit performs a project database creation process, thereby making it possible to create a project database while referring to not only project databases and project execution databases corresponding to past construction projects, but also analysis result information as insight data. This makes it possible to create an effective project database that utilizes insight data as a project database, and also simplifies the work of creating the project database itself.

[0018] A third characteristic configuration of the present invention is that the construction work support device is configured to be able to execute a project database creation process by the project database creation unit, a project execution database creation process by the project execution unit, a data analysis process by the database analysis unit, and an analysis result accumulation process by the information linkage unit, in each of a plurality of phases into which a construction life cycle is divided on a time axis; When the construction work support device performs the first support processing in a specific phase among a plurality of phases, as the first regression processing, the information linking unit sends analysis result information obtained in a phase later on the time axis than the specific phase from the group of databases to the project database creation unit, so that the analysis result information can be freely regressed across phases.

[0019] According to this configuration, when the first support process is performed in a specific phase, it is possible to refer to analysis result information obtained in a phase that is later on the timeline than the specific phase. Therefore, it is possible to create a project database for the specific phase based on insight data, etc. in a phase that is later on the timeline than the specific phase, and it is possible to efficiently create an effective project database.

[0020] A fourth characteristic configuration of the present invention is that, when construction work including decision-making is performed, in the first support process, the project database creation unit is configured to perform recommendation processing to support decision-making based on the analysis result information.

[0021] According to this configuration, when performing construction work including decision-making, it is possible to perform recommendation processing such as processing to present ratios or constants with a certain degree of appropriateness based on analysis result information, or processing to present a recommendation for selecting the best one from multiple options, etc. This allows project stakeholders to make efficient and accurate decisions, thereby effectively supporting construction work including decision-making.

[0022] A fifth characteristic configuration of the present invention is a method for producing a project database by the project database production unit, the project database production unit producing a project database by the project database production unit, The project execution unit is configured to be able to execute a second support process as the construction work support process in the project execution database creation process, which creates a project execution database using data linked in the data linking process by the project database creation unit.

[0023] The data linking process can be, for example, a process in which a common identifier is provided between the first data and the second data, and the identifier is used to call up the second data from the first data. This allows the project execution unit to easily call up the data of the databases linked by the data linking process when performing the second support process, and allows the project execution database to be created while referring to the called data, thereby enabling the project execution database to be created efficiently.

[0024] A sixth characteristic configuration of the present invention is that, in the project database creation process, the project database creation unit performs a data linking process between the project database to be created and the group of databases when the construction life cycle spans multiple phases divided on a time axis.

[0025] According to this configuration, the project database creation unit performs data linking processing between the project database and the database group across multiple phases, so that data that occurs separately in time series in each of the multiple phases can be linked with a single thread. This allows each department and organization to omit all of the work that has been done so far, such as transcribing and checking information generated in the previous process in the subsequent process as the process progresses, which means that semi-automation or partial automation can be achieved.

[0027] An embodiment of a construction work support system according to the present invention will be described with reference to the drawings. When carrying out a new construction project to build a new building, the construction life cycle is divided into multiple parts on a time axis, as shown in Figure 1, and the construction project is managed by dividing up the work into phases.

[0028] Here, the "construction life cycle" is defined as the period from the moment the intention to build a building arises to the moment the building is destroyed. In Figure 1, the construction life cycle is divided into several phases (pH), such as "0pH planning and development period," "1pH basic planning period," "2pH basic design period," "3pH detailed design period," "4pH construction preparation period," "5pH construction period," and "6pH facility maintenance and management period."

[0029] Construction work is performed to advance a project in each of the multiple phases divided in the construction life cycle. In the early stages of the construction project's "planning and development period" and "basic planning period", construction work such as deciding the site, deciding on the combination of the functions and scale of the facilities to be included in the building, and calculating and forecasting the construction project income and expenditure plan and construction budget occurs. In phases such as the "basic design period", construction work such as considering and deciding on the layout of the building on the site, the layout of the facilities on each floor, and the design conditions for the structure and equipment occurs. In phases such as the "detailed design period", construction work such as deciding on the materials, specifications, and quantities of each part that makes up the building occurs. In phases such as the "construction period", construction work such as making contracts with subcontractors who will actually construct the building, ordering materials, and managing the construction process occurs.

[0030] As such, the construction work required to advance a construction project involves a variety of decision-making tasks, including the size, layout, and design of the building, as well as the materials, equipment, structure, and their combinations to be used. In addition to these decision-making tasks, a large number of other construction tasks also arise based on these decisions, such as the preparation of calculations to examine function and performance, quantity calculations, estimate calculations, construction plans, and order documents.

[0031] Therefore, as shown in FIG. 2, a construction work support device 100 is provided that can execute a construction work support process to support construction work using project performance information acquired during past construction projects. This construction work support device 100 uses data, databases, and digital technology to digitize various information (information groups from which experience values, know-how, etc. can be extracted) acquired during past construction projects and accumulates it as project performance information. When a new construction project is undertaken, the construction work support process is executed for various project stakeholders involved in the construction work, thereby serving as an information processing system that supports construction work using the accumulated project performance information. Here, "project stakeholders" broadly includes building owners, business owners, design offices, cost estimation offices, suppliers of construction materials, construction companies, cooperating companies that actually carry out the construction of the building, building users, etc.

[0032] The construction work support device 100 is capable of executing construction work support processing throughout the entire construction life cycle, not just in a specific phase of the construction life cycle, when proceeding with a new construction project. This allows construction work to be appropriately supported throughout the entire construction life cycle, improving the work efficiency of construction work throughout the entire construction life cycle, and effectively improving work efficiency throughout the entire construction life cycle.

[0033] As shown in FIG. 2, the construction work support device 100 includes a project database creation unit 101, a database group 201, a project execution unit 301, a database analysis unit 401, and an information linking unit 501 that exchanges information between the project database creation unit 101, the project execution unit 301, the database group 201, and the database analysis unit 401 to link the various units.

[0034] (Project Database Creation Department) The project database creation unit 101 performs a project database creation process to create a project database for a construction project. The project database is a set of information equivalent to conventional design documents, which is combined with a BIM model. For example, the project database is a collection of data that describes the functions and areas of the facilities that make up a building, as well as the materials and equipment required for construction, the structural materials, their specifications, and quantities, etc., by part or other method. By creating a digital twin that links the BIM model, which is a collection of the layout, shape, and position of facilities and materials, to the project database, it serves the function of replacing conventional design documents.

[0035] By performing the project database creation process in the project database creation unit 101, for example, based on the building use, location, functions, performance, etc. required by the customer, design conditions, requirements, specifications, etc. that match or are estimated to match the conditions from the database group 201, and project stakeholders such as designers and architects use the called data to select materials, etc. to be used in a new construction project, and the selected information, etc. is digitized to create a new project database.

[0036] The project database creation unit 101 is equipped with a first input device 102 into which various information can be freely input, a prediction model 103 which performs processing such as predicting materials, specifications, quantities, etc. according to requirement information using the input information of the first input device 102 as requirement information, a first processing device 104 which constructs a project database by digitizing selected information, etc. selected by project stakeholders from the prediction data, etc., and a project database unit 105 which stores the project database constructed by the first processing device 104. The project database creation unit 101 performs a project database generation process by performing prediction processing, etc. of the prediction model 103 and digitization processing, etc. of the first processing device 104.

[0037] (Project Execution Department) The project execution unit 301 performs a project execution database creation process using the project database created by the project database creation unit 101 as input information, and performs calculations and the like on the project database to create a project execution database required to execute a project.

[0038] The project execution database contains the calculations and other documents necessary to execute a project, using the project database as input information. Examples of these calculations include construction plans, performance calculations, quantity calculations, estimate calculations, cost breakdowns, procurement / purchasing plans, order instructions, and construction instructions.

[0039] The project execution unit 301 is equipped with a second processing device 302 that performs project execution database creation processing, a first output device 303 that outputs the project execution database created by the second processing device 302, and a project execution database unit 304 that stores the created project execution database.

[0040] (Databases) The database group 201 accumulates databases including information necessary for the project database creation unit 101 to create a project database and for the project execution unit 301 to create a project execution database.

[0041] The databases are roughly divided into two categories: plan databases (A-H) and market databases (J-M). The plan databases include, for example, a client / customer database, a company resource database, a building facility function database, a building material database, a BIM model (a database relating to the layout, position, shape, etc. of buildings), a database for construction planning and construction management, a quality control database, as well as an analysis result information database of the database analysis unit 401. The market databases include, for example, a site information database, a laws and regulations database, a manufacturer product database, a cooperating company database, etc.

[0042] The database group 201 includes a second input device 202 that allows various information for generating a database to be freely input, and a database section 203 in which various databases are accumulated and stored.

[0043] (Database Analysis Department) The database analysis unit 401 accumulates all the project databases created by the project database creation unit 101 and the project execution databases created by the project execution unit 301, and performs data analysis processing of the accumulated databases. By performing data analysis processing in the database analysis unit 401, it is possible to obtain analysis result information as insight data from the accumulated project databases and project execution databases, for the experience and know-how that have been accumulated by the project participants up until now.

[0044] The database analysis unit 401 includes a database storage unit 402 that stores a project database group and a project execution database group, a third processing device 403 that performs data analysis processing, a machine learning unit 404 that is used when the third processing device 403 performs the data analysis processing, and a second output device 405 that can freely output analysis result information from the data analysis processing of the third processing device 403.

[0045] (Information and Coordination Department) The information linking unit 501 links the various units by exchanging information between the project database creation unit 101, the project execution unit 301, the database group 201, and the database analysis unit 401. For example, when the project database creation unit 101 performs a project database creation process, the information linking unit 501 can call up data to be called out of the data stored in the database group 201 to the prediction model 103 of the project database creation unit 101, thereby creating a project database while utilizing the data. When the project execution database creation process is performed in the project execution unit 301, the information linking unit 501 can also call up data to be called out of the data stored in the database group 201 to the second processing device 302 of the project execution unit 301, thereby creating a project execution database while utilizing the data.

[0046] The information linking unit 501 is configured to be capable of executing an analysis result accumulation process for sending the analysis result information obtained by the database analysis process by the database analysis unit 401 to the database group 201 and accumulating the analysis result information in an analysis result information database related to the analysis result information. The analysis result information database is database H in Fig. 2, and analysis result information is accumulated as insight data in this database H by performing the analysis result accumulation process in the information linking unit 501. This part is called a regression circuit because information obtained from past project information is used to predict the creation of new project information.

[0047] In this way, the construction work support device 100 is capable of executing various processes such as project database creation processing by the project database creation unit 101, project execution database creation processing by the project execution unit 301, data analysis processing by the database analysis unit 401, and analysis result accumulation processing by the information linkage unit 501.

[0048] As shown in FIG. 3, the construction work support device 100 is configured to be able to execute the following processes in each of the multiple phases in the construction life cycle: project database creation processing by the project database creation unit 101, project execution database creation processing by the project execution unit 301, data analysis processing by the database analysis unit 401, and analysis result accumulation processing by the information linkage unit 501.

[0049] In FIG. 3, in each of the multiple phases, a project database creation unit 101, a project execution unit 301, a database analysis unit 401, etc. perform each process while being supported by a database group 201. In order to distinguish which phase the process is in, the project database creation unit "0ph"-101 is indicated before the code, indicating which phase the process is in.

[0050] Hereinafter, when it is necessary to distinguish which phase the processing is in for the project database creation unit 101, the project execution unit 301, the database analysis unit 401, etc., the phase in which the processing is in will be indicated before the symbol.

[0051] For example, as shown in FIG. 3, in the "0ph planning and development period", the project database creation unit 0ph-101 performs a project database creation process for 0pH to create a project database for 1pH. Using the created project database for 0pH, the project execution unit 0ph-301 performs a project execution database creation process for 0pH to create a project execution database for 0pH. Using the created project database for 0pH and the project execution database for 0pH, the database analysis unit 0ph-401 performs a data analysis process to obtain analysis result information. Using the analysis result information, the information linking unit 501 performs an analysis result accumulation process to accumulate analysis result information in the analysis result information database 0ph-203 (corresponding to database H of the database unit 203 in FIG. 2). Incidentally, since the analysis result information is output from the second output device 405, in FIG. 3, the analysis result information is indicated by using the symbol of the second output device 405, such as "0ph-405". This continuous flow, from the creation of the project database by the project database creation unit 101, through the creation of the project execution database by the project execution unit 301, storing the analysis result information of the data analysis by the database analysis unit 401 in the database group 201, and then feeding the result back to the creation of the project database by the project database creation unit 101, is called a "single loop processing."

[0052] In this way, in the construction life cycle, the construction project will proceed while the construction work support device 100 performs the above-mentioned "full-cycle processing" not only in the "0ph planning and development period" but also in each phase from the "1ph basic planning period" to the "6ph facility maintenance period."

[0053] Therefore, when construction work was carried out for a past construction project, the construction work support device 100 performs a round of processing divided into each of the above-mentioned phases, and acquires and stores the project database created, the project execution database created, and the analysis result information database H stored in the database group 201 as project performance information related to the past construction project.

[0054] When proceeding with a new construction project, when construction work is carried out in each of multiple phases in the construction life cycle, the construction work support device 100 is configured to be able to execute the first support process while performing the above-mentioned "full-round processing" as a construction work support process that supports construction work using project performance information related to past construction projects.

[0055] In the first support process, the information linking unit 501 performs a first regression process of sending analysis result information accumulated in the analysis result information database (database H) from the database group 201 to the prediction model 103 of the project database creation unit 101 to regress the analysis result information, as indicated by the thick arrow in Fig. 4, and the project database creation unit 101 performs a project database creation process of creating a project database using the analysis result information. As a result, the information linking unit 501 calls up the analysis result information from database H, which is the analysis result information database, to the prediction model 103 of the project database creation unit 101, so that the prediction model 103 can make effective predictions using the analysis result information and the project database can be created efficiently.

[0056] In this first support process, as shown in FIG. 4, the information linking unit 501 performs a first regression process to regress the analysis result information from the analysis result information database (database H) to the prediction model 103. However, as shown in FIG. 3, the information linking unit 501 not only regresses the analysis result information in the same phase as the first regression process, but also sends analysis result information obtained in a phase later on the time axis than a specific phase from the analysis result information database (database H of the database group 201) to the prediction model 103, so that the information linking unit 501 is configured to freely regress the analysis result information across phases.

[0057] For example, as shown in Fig. 3, the information linking unit 501 can regress the analysis result information stored in the analysis result information database 2ph-203 for the "2ph basic design period" to the prediction model 0ph-103 for the "0ph planning and development period" and the prediction model 1ph-103 for the "1ph basic planning period". The information linking unit 501 can regress the analysis result information stored in the analysis result information database 5ph-203 for the "5ph construction period" to the prediction model 0ph-103 for the "0ph planning and development period", the prediction model 1ph-103 for the "1ph basic planning period", the prediction model 2ph-103 for the "2ph basic design period", the prediction model 3ph-103 for the "3ph detailed design period", and the prediction model 4ph-103 for the "4ph construction preparation period".

[0058] In this way, the information linking unit 501 regresses the analysis result information across phases, so that it can refer to the analysis result information acquired in a phase later on the timeline than the specific phase, and can effectively perform processing such as prediction in the prediction model 103 while looking ahead to information required for a phase later on the timeline than the specific phase, thereby making it possible to efficiently create an optimized project database within a range that makes use of the results of data analysis from past performance information.

[0059] In the project database creation unit 101, predictions and other processing is performed using a prediction model 103, while the first processing device 104 performs data linking processing between the project database to be created and the database group 201, as shown in Fig. 13. In Fig. 13, for example, a portion of the project database to be created in "2ph basic design period" is shown on the right side, and item data to be registered from the material database D to which the project database is to be linked is shown on the left side. In this case, the first processing device 104 links the toilet A in the material database D with the toilet A in the project database by inputting into the project database the same ID number as the corresponding "toilet A" in the material database D, or by specifying the item data of "toilet A" and specifying registration.

[0060] When the project database creation unit 101 creates a project database, such data linking processing is performed, so the construction work support device 100 is configured to be able to execute, in addition to the first support processing, a second support processing that utilizes the data linking processing as a construction work support processing.

[0061] In the second support process, the project execution unit 301 creates a project execution database using data linked in the data linking process by the project database creation unit 101 in the project execution database creation process, as shown by the dotted arrow in Figure 12.

[0062] In the second support process, the item data linked in the data linking process is called from the database D to the second processing device 302 of the project execution unit 301. The second processing device 302 calls the linked item data using the project database stored in the project database unit 105 as input information, so that when creating the project execution database, it is possible to start work from a list of building materials as a collection of linked item data from the beginning.

[0063] As described above, the construction work support device 100 can execute the first support process and the second support process as construction work support processes, and these first support process and second support process are performed throughout the entire construction life cycle. This allows project stakeholders to identify which information in the previous phase generated specific information in a specific phase of the construction life cycle, and which information in the subsequent phase will generate it. In other words, the association of information across phases is semi-automated. This also allows various construction tasks to be omitted, effectively improving work efficiency throughout the entire construction life cycle.

[0064] Here, the first support process shown in Figure 4 has been given as an example of construction work support processing using analysis result information. In addition to this first support process, a third support process can also be performed in which the analysis result information is used to provide support when creating a project execution database.

[0065] In this third support process, as shown in FIG. 2, the information linking unit 501 performs a second regression process in which the analysis result information accumulated in the analysis result information database (database H) is sent from the database group 201 to the second processing device 302 of the project execution unit 301 to regress the analysis result information, and the project execution unit 301 uses the analysis result information to perform a project execution database creation process in which a project execution database is created.

[0066] Below, the first support process and the second support process will be explained, giving specific examples of the actions of each process in the project database creation unit 101, the project execution unit 301, the database analysis unit 401, the information linkage unit 501, and the database group 201, as well as the type of data that is handled.

[0067] [Example 1-1 of the first support process] As a specific example 1-1 of the first support process, a case of predicting the facility scale at the planning stage will be described with reference to Fig. 4 to Fig. 6. Fig. 4 to Fig. 6 show a case of predicting the area of ​​the surgery department of a hospital when planning a hospital in a new construction project.

[0068] As shown by the bold arrow in Figure 4, every time a construction project was carried out in the past, the project database at the time of the building's completion (see the right side of Figure 5) was obtained during the "5ph construction period," and the analysis results information obtained by analyzing that project database was stored in the analysis results information database (database H). Therefore, when proceeding with a new construction project this time, during the "0ph planning and development period," project stakeholders can predict the facility scale (area of ​​the surgery department) while referring to the analysis results information stored in the analysis results information database H.

[0069] As shown in Figure 4, during the "5ph construction period" of past construction projects, the project database unit 5ph-105 acquires the project database at the time of building completion (see the right side of Figure 5), so the process starts when the project database unit 5ph-105 performs a process to collect the project database to be collected (step #1 in Figure 4).

[0070] As shown on the left side of Fig. 5, for example, database A of database group 201 is a database related to customer information, and in past construction projects, database A has stored customer charts including company names, hospital types, and number of hospital beds, room names of each room linked to each department within the hospital already owned by the customer, planned building charts including total floor area, and customer requirements for the surgery department. Since the data in database A is linked to the data for each room contained in the project database, as shown on the left side of Fig. 6, for example, among project databases that hold information on multiple hospitals, project databases that have "number of hospital beds" in the customer chart are collected and these data are analyzed.

[0071] As shown in FIG. 4, the collected project database is sent by the information linking unit 501 from the project database unit 5ph-105 to the database storage unit 402 of the database analysis unit 401 and stored therein (step #2 in FIG. 4).

[0072] The third processing device 5ph-403 of the database analysis unit 401 performs data analysis processing to analyze multiple project databases PD1 to PDn (see the left side of Figure 6) stored in the database storage unit 402, as shown in Figure 4 (step #3 in Figure 4).

[0073] When the third processing device 5ph-403 performs data analysis processing, when a new project database is stored in the database storage unit 402, the machine learning unit 404 is used to perform update processing for updating the analysis result information.

[0074] Some of the many analytical processes performed in this analysis process are shown in Figure 6. For example, as shown on the right side of Figure 6, the first analytical information (relationship shown by the dotted line) showing the relationship between the number of ward beds and the number of operating rooms is an analysis that explores which factor determines the area of ​​the operating department, and the first analytical information is used to obtain second analytical information showing the relationship between the number of ward beds and the area of ​​one general operating room (relationship shown by the dotted line). In the analysis process, the second analytical information is further used to obtain third analytical information showing the relationship between the number of ward beds and the department area ratio of parts other than the operating rooms (relationship shown by the dotted line), and the third analytical information is used to obtain fourth analytical information showing the relationship between the number of ward beds and the area of ​​the operating department (relationship shown by the dotted line) in order to express the main factor that determines the area of ​​the operating department and the area of ​​the operating department, which is the target, as a function, and this fourth analytical information is obtained as analysis result information. By incorporating this data analysis result information into an algorithm and database H that can be called up in the prediction model 103 of this system, it becomes possible to predict, for example, the floor space of a surgical department from the number of beds in a ward.

[0075] As shown in Figure 4, when the third processing device 5ph-403 performs data analysis processing to obtain analysis result information, the second output device 405 outputs the analysis result information, and the analysis result information is accumulated in the analysis result information database (database H) of the database group 201 through analysis result accumulation processing by the information linkage unit 501 (step #4 in Figure 4).

[0076] In this way, by performing steps #1 to #4 during the “5ph construction period” of past construction projects, analysis result information for predicting the area of ​​the operating department from the number of ward beds is accumulated in the analysis result information database H.

[0077] In the "0ph planning and development period" of a new construction project, as shown in Fig. 4, when requirement information such as "number of hospital beds in the ward" is inputted by the first input device 102, the information linking unit 501 calls up data corresponding to the requirement information from the database group 201 to the prediction model 0ph-103, and the information linking unit 501 performs a first regression process to send the analysis result information accumulated in the analysis result information database (database H) to the prediction model 0ph-103 to regress the analysis result information (step #5 in Fig. 4). At this time, in the first regression process, the analysis result information acquired in the "5ph construction period" is regressed to the prediction model 0ph-103 in the "0ph planning and development period", so that the analysis result information is regressed across multiple phases from the later phase "5ph construction period" to the earlier phase "0ph planning and development period".

[0078] In the prediction model 0ph-103, for example, the analysis result information (see the bottom right of Figure 6), which is the fourth analysis information of the relationship between the number of ward beds and the area of ​​the operating department (relationship shown by the dotted line), is called up. Therefore, by referring to the analysis result information, project stakeholders can easily and accurately predict and recommend the first option, the first plan, for the area of ​​the operating department from the number of ward beds of the hospital in a new construction project.

[0079] In the database analysis process, the third processing device 403 of the database analysis unit 401 generates an algorithm that converts the analysis results into a format that can be used for decision-making, such as the fourth analysis information (see the lower right of FIG. 6) of the relationship between the number of ward beds and the area of ​​the surgery department (relationship shown by the dotted line) in the lower right. As a result, when performing construction work including decision-making, the algorithm can be effectively used to make decisions, and more effective support can be provided.

[0080] [Example 1-2 of the first support process] As a specific example 1-2 of the first support process, a case where design conditions are predicted will be described with reference to Fig. 7 to Fig. 9. Fig. 7 to Fig. 9 show a case where design conditions are predicted from building use information and room use information in a new construction project.

[0081] Unlike Specific Example 1-1 in which information required for a specific phase is extracted from an accumulation of performance information from a past, subsequent phase, Specific Example 1-2 performs the first support process using analysis result information from a group of multiple project databases acquired in the same past phase. As shown in Fig. 7, in the "2ph basic design period" of a past construction project, a project database related to design information is acquired, and the analysis result information obtained by analyzing the project database is stored in the analysis result information database H. In the "2ph basic design period" of a new construction project, project stakeholders can predict design conditions from building use information and room use information while referring to the analysis result information stored in the analysis result information database H.

[0082] As shown in Figure 7, during the "2ph basic design period" of a past construction project, the project database unit 2ph-105 acquires a project database related to design information (see the right side of Figure 8), so the process starts when the project database unit 2ph-105 performs a process to collect the project database to be collected (step #11 in Figure 7).

[0083] As shown on the left side of Fig. 8, for example, database A of database group 201 is a database related to customer information, and in past construction projects, planned building charts including building use information, customer requirements including room use information, etc. are accumulated in database A. The data in database A is linked to data in past project databases executed by the customer, and as shown in the center of Fig. 9, for example, for project databases for multiple building uses, the collection targets are project databases having "building use information" and "room use information," which are planning conditions, and project databases of "room design conditions," which are the results of planning.

[0084] The collected project database (see the center of FIG. 9) is sent from the project database unit 2ph-105 to the database storage unit 402 and stored therein, as shown in FIG. 7 (step #12 in FIG. 7).

[0085] As shown in Fig. 7, the third processing device 2ph-403 performs a data analysis process to analyze a plurality of project databases PD1 to PDn (see the center of Fig. 9) stored in the database storage unit 402 (step #13 in Fig. 7). In this analysis process, for example, as shown in Fig. 9, data analysis is performed on the causal relationship between the cause and effect of what design conditions were adopted for the combination of factors that cause the generation of design condition information, such as building owner attribute information, building use information, and room use information, and the adoption rate correlation that indicates which result information was adopted for which cause information is obtained as analysis result information.

[0086] As shown in Figure 7, when the third processing device 2ph-403 performs data analysis processing to obtain analysis result information, the second output device 405 outputs the analysis result information, and the analysis result information is accumulated in the analysis result information database (database H) of the database group 201 by the analysis result accumulation processing of the information linkage unit 501 (step #14 in Figure 7).

[0087] In this way, by performing steps #11 to #14 during the "2ph basic design period" of past construction projects, analysis result information for predicting the design conditions of each room from the building owner attribute information, building use information, and room use information is accumulated in the analysis result information database H.

[0088] During the "2ph basic design period" of a new construction project, as shown in FIG. 7, when requirement information such as "building use" and "room use" is entered into the first input device 102, the information linking unit 501 calls up data from the database group 201 that corresponds to or is highly similar to the customer requirement information, and sends it to the prediction model 2ph-103, and the information linking unit 501 performs a first regression process to send the analysis result information accumulated in the analysis result information database (database H) to the prediction model 2ph-103 and regress the analysis result information (step #15 in FIG. 7).

[0089] In the prediction model 2ph-103, analysis result information is called up, which is the adoption rate correlation that shows what design conditions are being adopted for the building use information and room use information. Therefore, project stakeholders can easily and accurately select design conditions for new construction projects by referring to the analysis result information, for example, by selecting design conditions with a high adoption rate.

[0090] In this specific example 1-2, the analysis result information, which is the adoption rate correlation, is regressed against the prediction model 2ph-103, so the project database creation unit 101 performs a recommendation process showing the adoption rate correlation based on the analysis result information. This allows project participants to determine suitable design conditions based on insight data obtained from the data analysis results, instead of the experience and know-how that have been accumulated by the project participants so far.

[0091] Incidentally, in Fig. 7, the case where the first support process is performed using the analysis result information acquired in the same phase has been described, but for example, the analysis result information can be acquired in the "3ph detailed design period". In this case, the analysis result information can be acquired by the project database unit (3ph)-105 and the third processing device (3ph)-403 in the "3ph detailed design period" in Fig. 7 performing processing.

[0092] [Example 1-3 of the first support process] As a specific example 1-3 of the first support process, a case of predicting the floor height of the reference floor and other floors will be described with reference to FIG. 10. In this case, during the "5ph construction period" of a past construction project, a project database at the time of building completion, etc. is acquired, and analysis result information obtained by analyzing the project database is stored in the analysis result information database H. During the "1ph basic planning period" and "2ph basic design period" of a new construction project, project stakeholders can predict the floor height of the reference floor and other floors while referring to the analysis result information stored in the analysis result information database H, and as a result, can predict the "maximum height" to which legal restrictions are applied.

[0093] In this specific example 1-3, compared to specific examples 1-1 and 1-2, the same processing is performed in the project database creation unit 101, database analysis unit 401, information linkage unit 501, and database group 201, so the focus of the explanation will be on what type of data is handled.

[0094] Referring to Figure 2, the project database unit 105 acquires various project databases (left side of Figure 10) including information on floor height, and these project databases are sent from the project database unit 105 to the database storage unit 402 and stored therein, and data analysis processing is performed by the third processing device 403 (see the center of Figure 10).

[0095] Regarding the floor heights of the standard floor and other floors, there is a track record of different floor heights being selected depending on the building use in past construction projects, so in the data analysis process, maximum, minimum, average, and other values ​​are obtained for the floor heights of the standard floor and other floors by building use, as shown in the center of Figure 10. For example, building uses are categorized into apartment complexes, hospitals, hotels, rental offices, etc., and maximum, minimum, average, and other values ​​are obtained for each of them.

[0096] Referring to Figure 2, when the third processing device 403 performs data analysis processing to obtain analysis result information, which is floor height information by building use (see the center of Figure 10), the second output device 405 outputs the analysis result information, and the analysis result information is accumulated in the analysis result information database (database H) of the database group 201 by the analysis result accumulation processing of the information linkage unit 501.

[0097] Referring to FIG. 2, in the "1ph basic planning period" or "2ph basic design period" of a new construction project, when requirement information such as "building use" and "reference floor and other floors" is entered into the first input device 102, the information linking unit 501 calls up data corresponding to the requirement information from the database group 201 into the prediction models 1pH-103 and 2pH-103, and the information linking unit 501 performs a first regression process, thereby sending the analysis result information accumulated in the analysis result information database (database H) to the prediction models 1pH-103 and 2pH-103 to regress the analysis result information.

[0098] In the prediction models 1pH-103 and 2pH-103, analysis result information, which is floor height information by building use (see the center of Figure 10), is called up, so that project stakeholders can easily and accurately determine the floor height of the standard floor in a new construction project, for example, by selecting the floor height according to the building use while referring to the analysis result information.

[0099] In Fig. 10, the data analysis process of the third processing device 403 shows an example of obtaining numerical values ​​such as maximum, minimum, and average values ​​for the floor height of the reference floor and other floors by building use in the upper center part of Fig. 10, but instead of or in addition to this data analysis process, analysis result information showing how much range there is above and below the average value for the floor height of the reference floor by building use can be obtained as shown in the lower center part of Fig. 10. By regressing such analysis result information into the prediction models 1pH-103 and 2pH-103, project personnel can determine the floor height of the reference floor while considering not only the building use but also how much range there is above and below the average value for that building use, and can select an appropriate floor height.

[0100] In this specific example 1-3, the analysis result information, which is the floor height information by building use (see the center of Figure 10), is regressed against the prediction models 1pH-103 and 2pH-103, so the project database creation unit 101 performs recommendation processing to show floor height information by building use, etc., based on the analysis result information. This allows project participants to determine the optimal standard floor height based on insight data obtained from the data analysis results, instead of the experience and know-how that have been personally accumulated by project participants up to now.

[0101] [Example 1-4 of the first support process] As a specific example 1-4 of the first support process, a case where ultra-rough estimate conditions are predicted from an equipment implementation database will be described with reference to Fig. 11. Fig. 11 shows a case where the presence and size of smoke exhaust equipment is predicted at a stage where there are no building plans or equipment plans.

[0102] In this case, unlike Specific Example 1-1 etc., referring to Fig. 2, a project database has been acquired in past construction projects, so the project execution unit 301 performs a project execution database creation process using that project database to acquire the project execution database. The database analysis unit 401 performs a data analysis process to analyze the acquired project execution database, and accumulates the analysis result information analyzed in this data analysis process in the analysis result information database H. In a new construction project, project stakeholders can predict the presence and size of smoke exhaust equipment by referring to the analysis result information accumulated in the analysis result information database H.

[0103] As shown on the left side of Figure 11, in the "2ph basic design period" of a past construction project, the project database unit 2ph-105 acquires a project database of architectural design drawings, etc., and in the "5ph construction period", the second processing device 5ph-302 inputs the project database of architectural design drawings, etc., performs a project execution database creation process, and creates a project execution database of the number of floors and number of smoke exhaust fans to be installed, smoke exhaust duct system diagram, smoke exhaust duct layout diagram, smoke exhaust duct construction diagram, smoke exhaust duct quantity table, etc. As a result, the project execution database unit 5ph-304 in the "5ph construction period" acquires a project execution database of smoke exhaust duct quantity sheets, smoke exhaust fan quantity sheets, etc.

[0104] As shown in the center of FIG. 11, the database analysis unit 5ph-401 in the "5ph construction period" performs data analysis processing to analyze the project execution database such as smoke exhaust duct manufacturing drawings. The database analysis unit 5ph-401 analyzes the information group such as building use and facility size obtained from the project database and the information group of the number of smoke exhaust ducts and the number of smoke exhaust fans obtained from the project execution database to obtain the installation trend of smoke exhaust equipment for each building use, and from the installation trend of smoke exhaust equipment for each building use, for example, obtains the relationship (relationship shown by the solid line) between the total number of hotel rooms obtained from the project database and the number of smoke exhaust ducts and smoke exhaust fans, and obtains the number of smoke exhaust ducts for each building use (for example, average value, minimum value, maximum value, etc.). In this way, the database analysis unit 5ph-401 obtains, for example, the number of smoke exhaust ducts for each building use (for example, average value, minimum value, maximum value) as analysis result information.

[0105] As shown in the upper right side of FIG. 11, the analysis result information acquired by the database analysis unit 5ph-401 is accumulated in the analysis result information database (database H) of the database group 201 by the analysis result accumulation process of the information linking unit 501.

[0106] As shown in the lower right-hand side of Figure 11, when requirement information such as "building use," "facility size," "number of floors," and "total floor area" is input using the first input device 102 during the "0ph planning and development period" of a new construction project, the information linking unit 501 calls up data corresponding to the requirement information from the database group 201 into the prediction model 0ph-103, and the information linking unit 501 performs a first regression process, so that the analysis result information accumulated in the analysis result information database (database H) is regressed to the prediction model 0ph-103.

[0107] In the prediction model 103, analysis result information is called up, which is the quantity of smoke exhaust ducts by building use (e.g., average value, minimum value, maximum value), so that project participants can accurately predict the quantity of smoke exhaust ducts according to the building use by referring to the analysis result information.

[0108] [Example 2-1 of the second support process] As a specific example 2-1 of the second support process, a case where an estimate statement, which is an example of a project execution database, is created using a project database will be described with reference to Figures 12 to 14. Figures 12 to 14 show a case where an estimate statement is created.

[0109] As shown in Fig. 12, in the "3ph detailed design period" of a new construction project, the project database unit 105 acquires a project database (see the right side of Fig. 13) of toilet design specification information, quantity information, etc. The second processing device 302 of the project execution unit 301 uses the project database (see the right side of Fig. 13) of the toilet design specification information, quantity information, etc. as an input database, and creates an estimate by performing calculation processing of an estimate creation tool, etc., as shown on the right side of Fig. 14.

[0110] As shown in Fig. 13, the first processing device 104 of the project database creation unit 101 performs data linking processing between a newly created project database and a construction material database that is part of the database group 201. In Fig. 13, for example, a project database created in "3ph detailed design period" is shown on the right side, and material database D to which the project database is linked is shown on the left side. For example, the first processing device 104 gives a unique ID number as property data to the item data of "toilet A" that corresponds to the material database D in the project database, and links the toilet A in the material database D with the toilet A in the project database.

[0111] When the project database is created by registering item data with unique ID numbers, such as toilet A, included in the project database in the project database creation unit 101, a data linking process is carried out. Therefore, in the second support process, as shown in FIG. 14, this data linking process is used to create an estimate statement, which is the project execution database.

[0112] As shown in Fig. 12, when the second processing device 302 performs a project execution database creation process, unit price information P1 and the like (see Fig. 14) including material costs, labor costs, transportation costs, and the like held by the item data linked in the data linking process can be called up to the second processing device 3ph-302 from the database D of the database group 201. The second processing device 3ph-302 can use the called-up linked data to create an estimated invoice, which is the project execution database.

[0113] For example, as shown in Figure 14, when creating an estimate for toilet A, washlet, toilet seat cover, control panel, flip-up pick-up, etc., the design price P1 of the toilet and other items in database D for toilet A is called up, and the estimate creation tool multiplies that estimated unit price P1 by the quantity Q1 obtained from the project database to calculate the subtotal of the estimated price for toilet A. Subtotals for the washlet, toilet seat cover, control panel, flip-up pick-up, and all other construction materials are calculated in the same manner as for toilet A, using linked data. In addition to design price, information can also be called up and calculations performed for other calculation methods such as estimated cost and construction execution cost by linking using identifiers in the same way.

[0114] In this way, when creating an estimate, which is one of the project execution databases, an estimate can be automatically created by utilizing the linked data that was linked in the data linking process when creating the project database, thereby reducing the workload of those involved in the project and effectively improving work efficiency.

[0115] Here, Fig. 13 shows an example of data linking processing using ID numbers when creating a project database, but as shown in Fig. 15, identifiers can be applied not only to construction materials, etc., but also to a complex set of chronological management phases, organizations, etc., and data linking processing can also be performed using a method such as creating a nested structure as a cohesive group.

[0116] Figure 15 shows the data structure related to the interior finish of a building, in which data is linked using multiple identifiers. As shown in Figure 15, information on a construction project is generated in chronological order in the order of management phases, and therefore, for each management phase in which the data is generated, an identifier 2 is given to the data group, indicating the time of occurrence in the chronological order. For example, in "1pH Basic Plan Period", an identifier 1 is given to the room name generated in the basic plan period phase of 1pH. As a result, in "1pH Basic Plan", the project database is a combination of the rooms with identifier 1 and the area of ​​each room that is generated. When proceeding to "2pH Basic Design Period", the room data of identifier 1 is handed over to identifier 2 indicating "2pH Basic Design Period", where item data with finishing material information is linked to each room data with identifier 1 by identifier 3. In the phases of "3pH Detailed Design Period" and "4pH Construction Preparation Period", in addition to identifier 1 and identifier 2 indicating the room name and phase, a more specialized identifier 4 indicating the construction item corresponding to the subcontractor that will actually carry out the interior finish is linked. In addition to the above, the identifier can be linked to organizational information that occurs within the process, such as the installation location, cost estimate, procurement, and supplier.

[0117] In this way, when executing a construction project, information about the construction project becomes more detailed and specialized as the phases progress (from left to right in Figure 15), so that new information is added while maintaining a certain degree of relevance to the information in the previous phase, and the amount of information increases.

[0118] Therefore, as shown in Fig. 15, the project database creation unit 101 performs data linking processing between the project database to be created and a group of databases in a state in which the construction life cycle spans multiple phases divided on a time axis by using multiple identifiers in the project database creation processing. For example, the project database creation unit 101 performs data linking processing across multiple phases in a form in which a different identifier is used for each phase.

[0119] By carrying out this linking process, data that occurs separately in time series in each of multiple phases can be linked with a single thread. For example, by using identifier 1, room data can be generated, and it becomes possible to know what data in a later phase is linked to the generated room data.

[0120] 2, for example, when project database creation processing is performed by project database creation unit 101, the linked data linked in the linking process can be called up in prediction model 103, allowing project personnel to refer to data linked with one thread across multiple phases. This allows all of this work, which has previously been done in each department or organization as the process progresses, to be omitted, i.e., semi-automation or partial automation can be achieved.

[0121] Therefore, in addition to the first and second support processes described above, the construction work support device 100 can also execute a fourth support process as a construction work support process in which the project database creation unit 101 calls up linked data that has been subjected to data linking processing across multiple phases in the project database creation process, and creates a project database.

[0122] Although the case where the project database creation process is performed by the project database creation unit 101 has been explained, similarly, when the project execution database creation process is performed by the project execution unit 301, by calling up linked data, which has been subjected to data linking process using multiple identifiers across multiple phases, into the second processing device 302, project stakeholders can create the project execution database while referring to data linked by a single thread across multiple phases.

[0123] Therefore, in addition to the first and second support processes described above, the construction work support device 100 can also execute a fifth support process as a construction work support process in which the project execution unit 301 calls up linking data that has been subjected to data linking processing across multiple phases in the project execution database creation process, and creates a project execution database.
