Description

Technical Field

[0001] The present invention relates to an estimation determination support system that helps determine the estimated amount of costs for construction, repair, etc. of buildings, structures, and the like.

Background Art

[0002] In order to maintain and preserve facilities such as buildings and structures like buildings, schools, hospitals, research institutes, factories, and houses, for these buildings or structures, there are tasks such as repairing and replacing old or damaged parts and various regular inspections related thereto, which are carried out regularly every year. However, when old or damaged parts are found, repairs are often requested individually, and the inspection times are managed separately. That is, the management for maintaining and preserving buildings or structures or facilities is often carried out for each building or structure or for each facility. Therefore, the contents of construction and repair costs vary from year to year, and the management costs for maintenance and preservation associated therewith vary, making it difficult to estimate the costs for maintenance and preservation in the following years.

[0003] When managing the matters necessary for maintaining and preserving facilities, even if there is an invention that devises an access method to the managed documents, such as that described in Japanese Patent Application Laid-Open No. 2018-124680 (Patent Document 1), there is no prior art document that describes how to manage the budget necessary for maintaining and preserving facilities.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present disclosure provides an estimate determination support system that can rationalize management costs and prevent unnecessary high costs from occurring when creating estimates for management costs for maintaining and servicing various buildings, structures, or equipment, etc., and can calculate a reasonable estimate amount.

Means for Solving the Problems

[0006] The estimate determination support system according to one aspect of the present disclosure is configured as follows. That is, an estimate determination support system having a storage means, a control means, and a display means, the storage means for recording a plurality of management items representing the content of tasks and the content of raw materials or wages, etc., the control means for calculating an estimated amount, which is the total cost of raw materials or wages, etc. required for executing each one of the plurality of tasks, and calculating an estimated total amount, which is the total cost of raw materials or wages, etc. required for executing all the tasks constituting the plurality of tasks, from the estimated amount, and the display means for creating a construction management list for displaying the content of the plurality of tasks in a list format, and the estimate determination support system including the estimated amount in the construction management list.

[0007] According to one aspect of the present disclosure, in order to calculate an estimated amount, which is the total cost of raw materials or wages, etc. required for executing each one of the plurality of tasks, the calculation criteria for the cost of raw materials or wages, etc. required for executing one task are clear, and since the calculation is also accurate, the risk of formulating abnormal costs can be reduced. And in order to calculate an estimated total amount, which is the total cost of raw materials or wages, etc. required for executing all the tasks constituting the plurality of tasks, from the estimated amount, the calculation criteria for the cost of raw materials or wages, etc. required for executing all the tasks are clear, and since the calculation is also accurate, the risk of formulating abnormal costs can be reduced. And having the display means for creating a construction management list for displaying the content of the plurality of tasks in a list format, and including the estimated amount in the construction management list, the estimated amounts of the plurality of tasks can be easily compared, and abnormal estimated amounts can be easily discovered.

[0008] According to one aspect of the present disclosure, the estimate determination support system can be an estimate determination support system that includes the estimated total amount in the construction management list. Since the estimate determination support system according to one aspect of the present disclosure includes the estimated total amount in the construction management list, it is possible to check at a glance the cost of all tasks.

[0009] According to one aspect of the present disclosure, the estimate determination support system can be an estimate determination support system in which the display means creates a construction management document that displays the content of the task. Since the estimate determination support system according to one aspect of the present disclosure is configured such that the display means creates a construction management document that displays the content of the task, the content of the task can be managed by this estimate determination support system and the content can be confirmed at any time.

[0010] According to one aspect of the present disclosure, the estimate determination support system can be an estimate determination support system in which the display means creates a breakdown document that displays the content such as raw materials or labor costs. Since the estimate determination support system according to one aspect of the present disclosure is configured such that the display means creates a breakdown document that displays the content such as raw materials or labor costs, the content of raw materials or labor costs that are specifically costly in the execution of the task can be managed by this estimate determination support system and the content can be confirmed at any time.

[0011] According to one aspect of the present disclosure, the estimate determination support system can be an estimate determination support system in which the storage means records a name similar to the name of raw materials or labor costs described in the standard unit price list in association with the name of the raw materials or labor costs. Since the estimate determination support system according to one aspect of the present disclosure is configured such that the storage means records a name similar to the name of raw materials or labor costs described in the standard unit price list in association with the name of the raw materials or labor costs, it is possible to query raw materials or labor costs that are specifically costly in the execution of the task with the standard unit price list. Therefore, it is possible to provide an appropriate estimate by excluding expensive raw materials or labor costs.

[0012] According to one aspect of the present disclosure, an estimate determination support system can be configured such that a display means displays, together with the approximate estimate amount, a standard estimate amount taking into account the description in the standard unit price table. According to one aspect of the present disclosure, in the estimate determination support system, since the display means displays, together with the approximate estimate amount, a standard estimate amount taking into account the description in the standard unit price table, it is possible to easily compare the cost entered by a construction worker or the like with the cost based on the standard unit price table. If there is a large difference in the amount, it is possible to easily find out where the difference lies.

[0013] According to one aspect of the present disclosure, an estimate determination support system can be configured such that the display means applies and displays a standard estimate amount taking into account the description in the standard unit price table as the approximate estimate amount. According to one aspect of the present disclosure, in the estimate determination support system, since the display means applies and displays a standard estimate amount taking into account the description in the standard unit price table as the approximate estimate amount, the cost based on the standard unit price table is reflected instead of the cost entered by a construction worker or the like. Therefore, it is possible to obtain an estimate in which high-cost and irregular estimates are excluded in advance.

Effect of the Invention

[0014] According to one aspect of the present disclosure, it is possible to effectively estimate the management costs required for maintaining and preserving various buildings, structures, or fixtures provided therein.

Mode for Carrying Out the Invention

[0016] The estimate decision support system of the present disclosure will be described in detail. This estimate decision support system is for the management (hereinafter also simply referred to as "management") of maintaining and preserving facilities such as buildings, schools, hospitals, research institutes, factories, houses, etc. and equipment provided in these facilities (hereinafter, these are collectively also referred to as "facilities, etc."). For the repair, replacement, maintenance of parts that become old or damaged in these facilities, etc., and furthermore, various periodic inspections, investigations, etc. related to these (hereinafter also referred to as "tasks"). Therefore, it is a system for effectively and appropriately determining the estimate amount when calculating in advance the cost related to the entire such work and determining the estimate amount.

[0017] <System Configuration> FIG. 1 is a system configuration diagram of the estimate decision support system 10. This estimate decision support system (hereinafter also referred to as the "system") 10 includes a management server 1, a facility owner terminal 2 (2a, 2b,...) used by a person in charge (hereinafter referred to as the "facility provider") who is the owner of the facility such as a building and who oversees the maintenance and preservation management of the facility, a construction worker terminal 3 (3a, 3b,...) used by a person in charge of on-site construction (hereinafter collectively also referred to as "on-site construction") such as construction workers and repair workers who perform work at the site of tasks such as construction and repair for the maintenance and preservation of the facility, and a system administrator terminal 4 (4a, 4b,...) used by the system administrator (hereinafter referred to as the "system responsible person") of the entire system, and these are connected to each other via a network 5.

[0018] The management server 1 receives instructions from various terminals 2, 3, and 4 via the network 5 and performs processing according to those instructions. The configuration of this management server 1 includes a central processing unit (CPU) that functions as an arithmetic unit and a control unit, a main memory device such as a RAM, an external memory device such as a hard disk or SSD, a communication device such as a modem, and a computer program, etc. These components constitute functional blocks described later.

[0019] The management server 1 may be a computer management server connected to a network other than the various terminals 2, 3, and 4, and can also be a management server that doubles as the computer of the system administrator terminal 4. Furthermore, it may be a cloud management server used for cloud computing.

[0020] The facility operator terminal 2 is a computer used by the facility operator and can be one or more computers 2a, 2b, ···. This facility operator terminal 2 is configured with a communication device capable of connecting to and communicating with a network such as an in-house LAN or the Internet. When the program is started and connected to the network, it can acquire and display the data stored in the management server 1, send the data input through the input device to the management server 1, or receive the data from the management server 1 and output it in the form of an email, etc. through the output device. The computer serving as this facility operator terminal 2 may be a so-called personal computer, a mobile phone terminal, a tablet terminal, or the like.

[0021] The construction worker terminal 3 is a computer used by those responsible for on-site construction of facilities and the like, and can be one or more computers 3a, 3b, ···. This construction worker terminal 3 is configured with a communication device capable of connecting to and communicating with a network such as an in-house LAN or the Internet. When a program is started and connected to the network, it can acquire and display data stored in the management server 1, transmit data input through an input device to the management server 1, or receive data from the management server 1 and output it in the form of an email or the like through an output device. The computer serving as this construction worker terminal 3 may be a so-called personal computer, or a mobile phone terminal, a tablet terminal, or the like.

[0022] The system administrator terminal 4 is a computer used by the system administrator, and can be one or more computers 4a, 4b, ···. This system administrator terminal 4 is configured with a communication device capable of connecting to and communicating with a network such as an in-house LAN or the Internet. When a program is started and connected to the network, it can acquire and display data stored in the management server 1, transmit data input through an input device to the management server 1, or receive data from the management server 1 and output it in the form of an email or the like through an output device. The computer serving as this system administrator terminal 4 may be a so-called personal computer, or the management server 1.

[0023] FIG. 2 shows the functional configuration of the management server 1 as a block diagram. As shown in FIG. 2, the management server 1 has a control means 11, an ID recognition means 12, a storage means 13, a display means 14, and other means 15 such as a communication means. The control means 11 controls the various means described below to operate so as to exhibit their functions, selects and extracts necessary data from the various data recorded in the storage means 13, classifies them by specific items according to the purpose, and performs operations such as aggregation.

[0024] The ID recognition means 12 has a function of recognizing predetermined ID information for identifying a person who can access the estimate determination support system 10. More specifically, for an access request from various terminals 2, 3, and 4 to the estimate determination support system 10, it determines whether the person has access rights, and if so, the degree or the scope of the access rights. For example, for an access request from the facility operator terminal 2, permission is granted if the facility to be accessed is under the management of the requester, but not if it is a facility other than the access target. Also, for an access request from the construction worker terminal 3, permission is granted if the facility to be accessed is the construction target of the requester, but not if it is a facility other than the construction target. The mode of determining the presence or absence of access rights based on a password is just an example.

[0025] The storage means 13 has a function of recording various elements necessary for the management of maintenance and preservation of facilities and the like as management items, and serving as a management item database. The display means 14 displays the management items recorded by the storage means 13 and the items obtained by processing by the control means 11 on various terminals 2, 3, and 4, outputs them as a report, and also displays the input screens on the various terminals.

[0026] The management server 1 can also be provided with various functions such as alert generation means for observing abnormal values and issuing alerts, and communication means for transmitting various outputs such as alert information and reports to various terminals that are output destinations such as the facility operator terminal 2 and the construction worker terminal 3.

[0027] <Functions of the System> The estimate determination support system 10 can create, display, or use various documents described below to assist in the estimate determination.

[0028] (1) Construction management document The construction management document indicates the content of work, that is, tasks related to the repair, replacement, maintenance of old or damaged parts of facilities, and various regular inspections and surveys related thereto. The content of the task includes items (management items) necessary to identify the task. For example, the management number of the task, the name of the task, the name and status of the facility etc. targeted by the task, countermeasures, the location where the task is carried out, the management source where the task occurs, the installation date, the necessity of task execution, the unit and quantity of task execution, the estimated cost, the standard estimated cost, the estimated cost proposed by the facility provider, remarks, and others can be exemplified.

[0029] Here, the estimated cost is the estimated cost of the necessary costs for executing the task, calculated based on the breakdown of construction work described later. The standard estimated cost is the estimated cost of the necessary costs for executing the task, calculated based on the breakdown of construction work considering the standard unit price table described later. The estimated cost proposed by the facility provider is the estimated cost of the necessary costs for executing the task, presented by the facility provider without relying on the breakdown of construction work. These items vary depending on the type of management of the facility etc., and are not limited to the above items. They may include other items, or do not necessarily have all of the above items.

[0030] An example of the construction management document is shown in Figure 3. The task described in the construction management document shown in Figure 3 is the asphalt exposed waterproofing work on the 2nd floor of the XX Cultural Hall, and the following descriptions corresponding to the above items are made. "Business plan" as the management source where the task occurs, "D-3" as the management number of the task, "Asphalt exposed waterproofing" as the name of the task, "XX Cultural Hall" as the name of the facility etc. targeted by the task, "2nd floor" as the location where the task is carried out, "Overall deterioration is seen" as the status of the facility etc. targeted by the task, "Renewal of asphalt exposed waterproofing" as its countermeasure, "May 2000" as the installation date, "Promote" as the necessity of task execution, "57m 2 " as the unit and quantity of task execution, "￥2,317,000" as the estimated cost, and "There is attachment XX" as the remarks. Note that Figure 3 shows some of the above management items.

[0031] In addition, for some of the above items, the following matters for explaining their content in more detail are described. The name of the task is "Consider whether to update the construction work once a year.", the location where the task is carried out is "Target the entire second floor.", the state of the facilities and the like targeted by the task is "The entire second floor is deteriorating in places. The degree of deterioration varies by location.", the countermeasure is "It is necessary for the workers to take necessary measures while checking the entire second floor.", and the remarks are "Attachment ○○ was created by ○○ Company on November 2nd."

[0032] In this way, by creating a construction management document for each task, the matters necessary for a single task can be managed in a single document called the construction management document. Therefore, regarding that task, the content can be known accurately by referring to this construction management document.

[0033] (2) Construction breakdown sheet The construction breakdown sheet shows the content of the matters (also referred to as "raw materials or labor costs, etc.") for which costs occur when executing the task, such as the raw materials or parts (also referred to as "raw materials, etc.") used in a single task or the labor costs when executing that task. The content of the raw materials or labor costs, etc. includes the items (management items) related to the raw materials or labor costs, etc. If all the various details for which costs occur in the execution of the task are described in the construction management document, the construction management document will become cumbersome. Therefore, the breakdown of the costs is separated from the construction management document and made into a separate sheet, which is the construction breakdown sheet.

[0034] Therefore, the content of the construction breakdown sheet includes, as matters related to raw materials or labor costs, etc., the items (management items) necessary to identify the breakdown of the costs that occur, and examples include management numbers, names of construction, repair, etc., types, names of raw materials, etc., quantities, units, unit prices, total amounts, estimated amounts, remarks, and so on. Alternatively, the standard names, standard unit prices, standard total amounts, and standard estimated amounts of raw materials, etc. can also be listed.

[0035] Here, the total amount is the estimate amount for each construction work, repair, etc., and the approximate estimate amount is the estimate amount of all construction works, repairs, etc. obtained by adding up the estimate amounts for each construction work, repair, etc. Also, the standard names of raw materials, etc. are the names of raw materials, etc. listed in the standard unit price table described later, the standard unit price is the unit price listed in that standard unit price table, the standard total amount is the estimate amount for each construction work, repair, etc. based on the standard unit price, and the standard estimate amount is the estimate amount of all construction works, repairs, etc. obtained by adding up the estimate amounts for each construction work, repair, etc. based on the standard unit price. These items vary depending on the task, and are not limited to the above matters, and may include other items, or do not necessarily have all of the above items.

[0036] An example of a breakdown sheet for construction work is shown in Fig. 4. What is described in the breakdown sheet for construction work shown in Fig. 4 are the matters where costs of raw materials, etc. required for the "Asphalt Exposed Waterproofing Work on the Second Floor of ○○ Cultural Hall" specified in the construction management document shown in Fig. 3 occur. In the breakdown sheet for construction work shown in Fig. 4, the following descriptions are made corresponding to the above items.

[0037] The name of the construction work, repair, etc. is "Asphalt Exposed Waterproofing Work", the types of construction work are "High-pressure Cleaning of Existing Waterproof Surface", "Removal of Existing Asphalt", "Drainage Outlet Repair and Drain Installation", "Installation of Degassing Cylinder", "Urethane Coating Waterproofing", etc., the name of raw materials, etc. is "Strainer", "Stainless Steel", "Poly Mat ○○, manufactured by ○○ Co.", etc., the quantities are numbers such as "114.0", "66", etc., the units are "m 3 ", "piece", etc., the unit prices are the unit prices of each part and the construction unit price, such as "￥450", "￥3,000", etc., and the total amount is the total amount obtained by multiplying the quantity and the unit price for each type of construction work, such as "￥51,300", "19,800", etc. There is no description in the remarks, but necessary additional notes, etc. can be described. And an approximate estimate amount column for recording the total of the costs for each construction work is also provided, so that the total estimate of the construction work, etc. for the task for which the construction management document is created can be understood. In Fig. 3, "￥2,317,000" is recorded as the approximate estimate amount.

[0038] (3) Construction Management List The construction management list consolidates a plurality of tasks indicated in the construction management document into a list format, and extracts and lists in a table format a part of the items indicating the content of the tasks in the construction management document. That is, it displays the content of a plurality of tasks arranged side by side.

[0039] The content of the tasks indicated in the construction management list can also be substantially the same as the content of the tasks indicated in the construction management document. Examples of items (management items) include the management number of the task, the name of the task, the name and status of the facility or the like targeted by the task, countermeasures, the location where the task is carried out, the management source where the task occurs, the installation date, the necessity of task execution, the unit and quantity of task execution, the estimated cost, the standard cost, the cost estimate proposed by the facility provider, the total estimated cost, the total standard cost, the total cost estimate proposed by the facility provider, remarks, and other items. Here, the estimated cost is the total amount of the estimates for each task, the standard cost is the total amount of the estimates for each task considering the amounts in the standard unit price table described later, the cost estimate proposed by the facility provider is the total amount of the estimates for each task presented by the facility provider without relying on the breakdown of the construction, the total estimated cost is the total amount of the estimates for all tasks obtained by adding up the estimated costs of all tasks, the total standard cost is the total amount of the estimates for all tasks obtained by adding up the standard costs of all tasks, and the total cost estimate proposed by the facility provider is the total amount of the estimates for all tasks presented by the facility provider without relying on the breakdown of the construction. These items vary depending on the type of management of the facility or the like, and are not limited to the above items. They may include other items or do not necessarily have all of the above items. Note that when simply referring to management items, in addition to the items indicating the content of the tasks shown in the construction management list, items related to raw materials or labor costs shown in the breakdown of the construction, and items necessary to identify the tasks shown in the construction management document are also included.

[0040] An example of the construction management list is shown in FIG. 5. The construction management list shown in FIG. 5 shows a list of tasks planned to be carried out in 20○○ at a facility owned by Company A, and includes, as one of the tasks, the "Asphalt Exposed Waterproofing Work on the Second Floor of the ○○ Cultural Hall" indicated as management number D-3 in the construction management document exemplified in FIG. 3. The row indicating the task identified by this control number D-3 contains the following items. "Business plan" as the source of the task generation, "D-3" as the control number of the task, "Asphalt Exposed Waterproofing" as the name of the task, "○○ Cultural Hall" as the name of the facility etc. targeted by the task, "2nd floor" as the location where the task is carried out, "Overall deterioration is observed" as the state of the facility etc. targeted by the task, "Renewal of asphalt exposed waterproofing" as the countermeasure, "2000" and "5" as the installation date, "Promote" as the necessity of task execution, "M2" as the unit of task execution, "57" as the quantity, "￥23,170,000" as the estimated amount, and "There is attachment ○○" as the remarks.

[0041] The same description as that indicated by this control number D-3 is also made for tasks with other control numbers. For example, what is indicated by the control number D-2 is the content of the task regarding the "Removal work of CS antenna at △△ Cultural Hall". And, "￥203,584,032" is recorded as the total estimated amount, and "￥195,165,230" is recorded as the standard total estimated amount.

[0042] The difference in the described matters between the construction management document shown in Figure 3 and the construction management list shown in Figure 5 is that, since the matters described in the list are limited, some important matters among the matters described in the construction management document are described in the construction management list. For example, in the construction management document of Figure 3, in the column of the state of the facility etc. targeted by the task, it is described as "Overall deterioration is observed. There are deteriorations here and there across the entire 2nd floor. The degree of deterioration varies depending on the location.", but in the construction management list of Figure 5, it is limited to "Overall deterioration is observed".

[0043] Just by looking at this construction management list, the task with the above control number D-3 is that "In the business plan of Company A, asphalt exposed waterproofing work is planned for the 2nd floor part installed in May 2000 at the ○○ Cultural Hall. Based on the investigation results that overall deterioration is observed, 57m 2It can be seen that "the renewal of the exposed waterproof work over [a certain period] was promoted." Similarly, for other tasks with management numbers, the content can be understood to be of the same level as the task with management number D-3.

[0044] By creating a construction management list, it is possible to cover all the tasks necessary for the management of owned facilities, etc., and classify them from a desired perspective. For example, if all tasks are covered and divided by a deadline of one year, it is possible to list the tasks required for the management of facilities, etc. in 20〇〇. Alternatively, it may be classified by facilities, etc., or classified by the name of the task, etc.

[0045] (4) Standard unit price list The standard unit price list shows the standard prices and standard names of various raw materials, etc. It is a list of the raw materials, etc. recognized by the constructor, such as parts that can already be adopted under suitable conditions after negotiations with manufacturers, etc., and the prices attached to them. Therefore, if the raw materials, etc. listed in the standard unit price list can be used at their unit prices, the cost can be judged to be appropriate. The names and prices of the raw materials, etc. displayed in this standard unit price list are recorded in the storage means 13.

[0046] <System flow> The estimate decision support system 10 creates, displays, or uses the above-mentioned document according to the following flow.

[0047] The first flow (Figure 6): The first flow is shown in Figure 6 and will be described below.

[0048] 1. Creation of construction management document (s11) When the facility operator inputs specific items described in each item of the construction management document through the input form previously created by the display means 14 from the facility operator terminal 2, the storage means 13 records the input items as management items, and the recorded data is accumulated in the record database. Then, in accordance with the instruction to create a construction management document from the facility operator terminal 2 by the facility operator, the control means 11 calls the items recorded as each item recorded in the storage means 13, and the display means 14 outputs the construction management document in a format shown in, for example, FIG. 3.

[0049] However, at the stage before the breakdown of construction costs document is created, the estimated amount is not recorded, and only the estimated amount proposed by the facility operator is recorded if there is any. This is because the estimated amount cannot be calculated if the construction work etc. is not specified. More specifically, the instruction to create a construction management document is an instruction to view or print the construction management document. For the view instruction, the display means 14 displays the construction management document on the display of the facility operator terminal 2, and for the print instruction, the control means 11 prints the construction management document created by the display means 14 through the printer of the facility operator terminal 2. This step is shown as s11 in FIG. 6.

[0050] 2. Creation of breakdown of construction costs document (s12) When the construction worker inputs specific items described in each item of the breakdown of construction costs document through the input form previously created by the display means 14 from the construction worker terminal 3, the storage means 13 records the input items as management items, and the recorded data is accumulated in the record database. Then, in accordance with the instruction to create a breakdown of construction costs document from the construction worker terminal 3 by the construction worker, the control means 11 calls the items recorded as each item recorded in the storage means 13. The control means 11 calculates the total amount of the raw materials etc. from the unit price and quantity of the raw materials etc., and also calculates the total amount which is the total of the prices of a plurality of raw materials etc. Then, the display means 14 outputs the breakdown of construction costs document in a format shown in, for example, FIG. 4.

[0051] The instruction for creating the construction breakdown document is, more specifically, an instruction for viewing or printing the construction breakdown document. For the viewing instruction, the display means 14 causes the construction breakdown document to be displayed on the display of the construction worker terminal 3, and for the printing instruction, the control means 11 causes the construction breakdown document created by the display means 14 to be printed through the printer of the construction worker terminal 3. Since the construction breakdown document is created for each task, a plurality of construction breakdown documents can be created from a plurality of tasks. This step is shown as s11 in FIG. 6. Since the cost related to the task can be obtained as an estimated amount by creating the construction breakdown document, this estimated amount is also reflected in the estimated amount of the construction management document. This step is shown as s14 in FIG. 6.

[0052] 3. Creation of the construction management list (s13) By the facility operator performing a search from the facility operator terminal 2 with the necessary items according to the purpose of managing the facility, etc., the control means 11 extracts a plurality of tasks in units of construction management documents that meet the conditions from the storage means 13, and extracts the content that has been determined in advance to be recorded in the construction management list from the content described in the construction management document, and the display means 14 creates a construction management list in a list format.

[0053] Although it can be appropriately determined which items among the items described in the construction management document are to be recorded in the construction management list, as an example, as also explained in the difference between FIG. 3 and FIG. 5, among the items described in the construction management document, detailed explanatory items that would make the explanation long can be omitted. Also, some items of the construction management document can be made not to be displayed in the construction management list. In the column for the estimated amount of each task, the estimated amount of the construction breakdown document is displayed. Also, in the column for the total estimated amount, the amount obtained by the control means 11 summing up the estimated amounts of each task is displayed by the display means 14. Note that in this first flow, since the standard unit price table described later is not used, items taking into account the standard unit price table, such as the description of the standard total estimated amount, are not displayed in the construction management list. This step is shown as s13 in FIG. 6.

[0054] 4. Linkage of the three documents The construction management document, the breakdown of construction costs document, and the construction management list are linked by the task management number. The estimated cost column in the construction management document is initially blank, but after creating the breakdown of construction costs document and determining the total amount of the construction work etc. related to that task, it is displayed in the estimated cost column of the construction management document. Similarly, the estimated cost of the breakdown of construction costs document is reflected in the estimated cost column of each task in the construction management list. That is, the control means 11 applies the estimated cost of the breakdown of construction costs document recorded by the storage means 13 to the estimated cost of the construction management document and the construction management list in accordance with the display instruction of the construction management document by the facility owner, the creation instruction of the construction management list, etc. Also, when creating the construction management list, the control means 11 calculates the total estimated cost of all tasks obtained by summing up the estimated costs of each task.

[0055] The output of these documents is carried out not only in accordance with the output instructions of each document by the operator who has the right among the system administrator, the facility owner, the construction worker, etc., but also by the cooperation between the documents. For example, by setting the operation of the operator who clicks on the remarks column of the construction management document or the construction management list as the output instruction of the breakdown of construction costs document, the control means 11 can display the breakdown of construction costs document corresponding to that task on the display means 14. Alternatively, by setting the operation of the operator who clicks on the management number column of the breakdown of construction costs document as the output display of the construction management document, the control means 11 can display the construction management document corresponding to that task on the display means 14.

[0056] The estimated cost, which is the cost required when executing each individual task, is determined by creating each breakdown of construction costs document, and that amount can be displayed as the estimated cost in the construction management document or the construction management list. Therefore, the estimated costs of multiple tasks can be compared in the list, and the amount of costs between tasks can be easily checked. Therefore, irregular estimated costs can be easily found.

[0057] The second flow (Figure 7): The second flow is shown in FIG. 7 and will be described below. The second flow is a flow having steps in which the contents such as raw materials in the work breakdown sheet are collated with the standard unit price list and the description in the standard unit price list is reflected in the work breakdown sheet. The second flow is the one added to the first flow. Therefore, since the steps s11 to s13 described in the first flow are the same in the second flow, the description thereof will be omitted.

[0058] 5. Collation between the work breakdown sheet and the standard unit price list (s15) The name described in the name column of the raw materials etc. in the work breakdown sheet is collated with the name in the standard unit price list. That is, in the storage means 13, names similar to the names defined in the standard unit price list are registered in advance, and the control means 11 determines whether the name described in the name column of the raw materials etc. in the work breakdown sheet matches or is similar to this similar name. If they match or are similar, the name in the standard unit price list associated with that name is newly assigned. For example, if "air conditioner" and "air-conditioning machine" are registered as similar names in advance, and the description in the work breakdown sheet is "air conditioner" while the name defined in the standard unit price list is "air-conditioning machine", then "air-conditioning machine" is assigned to the name described in the work breakdown sheet.

[0059] A more specific method is, as the first method, to register in advance several names similar to the names defined in the standard unit price list, and when the name described in the name column of the raw materials etc. in the work breakdown sheet matches this similar name, assign the name defined in the standard unit price list. In this first method, it is necessary to register the similar names in advance, and if it does not match the registered similar names, the assignment to the name defined in the standard unit price list is not performed.

[0060] The second method is to equip the control means 11 with artificial intelligence and operate the artificial intelligence using the registered similar names as teaching data. In this case, even if a name similar to but slightly different from the registered similar name is described in the name column of the raw materials etc. in the work breakdown sheet, the assignment to the name defined in the standard unit price list may be performed. It is preferable to adopt a second method to eliminate the inconvenience that the display and assignment to unit prices cannot be made in the standard unit price table due to fluctuations in notation.

[0061] The assigned name can be listed together with the original name in the construction breakdown sheet, or the assigned name can be used to replace the original name and be indicated in the construction breakdown sheet. It is only necessary to determine in advance which display to select. Similarly, the unit price based on the assigned name can be listed together with the unit price based on the original name in the construction breakdown sheet, or the unit price based on the assigned name can be used to replace the unit price based on the original name and be indicated in the construction breakdown sheet. It is only necessary to determine in advance which display to select.

[0062] When listing together, columns for the standard name, standard unit price, standard total amount, and standard estimate amount of raw materials, etc. are provided and applied together with the name, unit price, total amount, and estimated amount of raw materials, etc. When replacing, the replaced content is recorded in the columns for the name, unit price, total amount, and estimated amount of raw materials, etc., and there is no need to provide columns for the standard name, standard unit price, standard total amount, and standard estimate amount of raw materials, etc. This step is shown as s15 in Figure 7.

[0063] When various constructors, etc. record the names of raw materials, etc. described in the construction breakdown sheet, various names of raw materials, etc. are used, and even for the same raw materials, etc., different notations may be used. Then, even if the unit prices are different, it is difficult to distinguish whether the unit prices are different due to different raw materials, etc. or whether the unit prices are different despite the same raw materials, etc. Therefore, it is preferable that the same name is given to the same raw materials, etc.

[0064] 6.3 Linkage of Three Documents Similar to what was shown in the first flow, in the second flow as well, there is no difference in that the construction management document, the construction breakdown sheet, and the construction management list are linked by the task management number. However, in the second flow, since there is a comparison with the standard unit price list, the content of the breakdown statement of work created according to the standard unit price list is reflected in the work management document and the work management list. The estimated amount column in the work management document is initially blank, but by creating a breakdown statement of work and determining the estimated amount of work related to that task, it is displayed in the estimated amount column of the work management document. However, in this case, when the estimated amount calculated from the unit price assigned using the standard unit price list, that is, the standard estimated amount, is also noted, the standard estimated amount is noted together with the estimated amount.

[0065] The same applies to the work management list. When the estimated amount takes into account the standard unit price list, that becomes the estimated amount, and when displayed separately, the standard estimated amount is noted together. In the case of the estimated amount that takes into account the standard unit price list, the total estimated amount is also calculated from that value, and when displayed separately, the total standard amount is noted separately from the total estimated amount. That is, the control means 11 applies the estimated amount or standard amount of the breakdown statement of work recorded by the storage means 13 to the estimated amount or standard amount, and the total estimated amount or total standard amount of the work management document and the work management list in accordance with the display instruction of the work management document or the creation instruction of the work management list by the operator with the right of origin.

[0066] In the case of the second flow compared to the first flow, in addition to the advantages of the first flow, there are the following advantages. That is, since the cost (standard estimated amount) required when executing each task is calculated based on the standard unit price of raw materials, etc., the adoption of expensive raw materials, etc. can be prevented, and the increase in the estimated cost can be suppressed.

[0067] Other flows: As another flow, there is a flow of creating a work management list without creating a work management document. That is, it is a method of directly performing the matters described in the work management document when creating the work management list.

[0068] More specifically, for the creation of the construction management list, when the facility operator inputs specific matters described in each item of the construction management list from the facility operator terminal 2 through the input form previously created by the display means 14, the storage means 13 records the input matters as management items, and they are accumulated in the record database. Then, in accordance with the instruction for creating the construction management list from the facility operator terminal 2 by the facility operator, the control means 11 calls the matters recorded as each item recorded in the storage means 13, and the display means 14 outputs the construction management list in a format such as shown in FIG. 5, for example. However, even in this case, at the stage before the creation of the breakdown of construction costs, the estimated estimate amount and the standard estimate amount are not described, and only the estimate amount proposed by the facility operator is recorded if there is such an amount. This is because the estimate amount cannot be calculated unless the construction work, etc. becomes specific. The creation of the breakdown of construction costs is the same as the method shown in the above flow.

[0069] The above embodiments are examples of the present invention, and within the scope not departing from the gist of the present invention, changes to the embodiments or addition and combination of known technologies, etc. can be made, and those technologies are also included in the scope of the present invention.
