Description

The present invention is primarily intended for use by equipment construction contractors who install various types of equipment associated with buildings, such as lighting equipment such as ceiling lights, air conditioning equipment such as air conditioners, and sanitary equipment such as plumbing, etc., in various types of construction work. A method and equipment for creating cost estimates for facility work that allows for easy calculation of cost estimates based on the cost estimate of equipment contents when in charge of facility work at the request of a constructor of the object itself and to present the cost estimate to the constructor. This invention relates to a construction cost estimate creation support device.

Traditionally, when constructing various types of buildings, for example, the general contractor who undertakes the construction is in charge of the main structure, and the lighting equipment, air conditioning equipment, sanitary equipment, etc. related to the building are handled by the respective specialist equipment construction companies. The work is outsourced to a certain facility construction company. When contracting out work, we examine construction cost estimates provided by equipment construction companies, select the equipment construction company we deem appropriate, and place orders.

Here, in order to prepare a quotation at a facility construction company, we refer to drawings, outline documents, etc. that explain the contents and specifications of the building, and select the various types of equipment required, that is, the quantity of equipment materials, etc. It is created by adding up specifications, manufacturer name, model number, etc., checking the unit price, and calculating the total cost. However, in recent years, as buildings have become larger and equipment has become more diverse, equipment construction companies have to select and estimate the appropriate equipment for each building, and use various cost estimation materials, unit price lists, etc. to calculate estimates. , which is extremely troublesome.

Therefore, equipment construction companies request a specialized cost estimation office to estimate the selection of various equipment, and based on the estimation quantity record (so-called picked-up data) provided by the estimation office, they then estimate the cost of equipment, materials, etc. We have asked multiple agencies, manufacturers, etc. to deliver such products. Next, the facility construction company compares and contrasts the estimate data calculated by the agency, etc., adopts the estimate data of the agency, etc. that has presented the optimal estimated price, and sends the cost estimate prepared by the facility construction company to the contractor. has been submitted to.

The collected data created by a cost estimation office that receives a cost estimation request from such an equipment construction company is created and provided by a cost estimation program that is independently adopted by the cost estimation office. Furthermore, the estimate data created by an agency or the like that receives a quotation request from an equipment construction company is similarly created and provided by an estimate program that the agency or the like employs independently. The equipment construction company inputs the collected data provided by the cost estimate office and the estimate data provided by the agency into its own computer, and creates a cost estimate for the equipment construction company.

In this current situation, data collected by quantity surveying offices and estimate data provided by agencies, etc. are created independently by each company, so the equipment construction companies that provide these data also have to re-enter the data and perform equipment construction work. The company is organizing and considering the matter on its own. This re-input of various data by the equipment construction company is extremely troublesome because input errors are likely to occur and verification thereof is also required.

Therefore, conventionally, for example, a construction cost estimation system and program shown in Patent Document 1, a cost estimate preparation device and program shown in Patent Document 2, a cost estimation device for equipment work shown in Patent Document 3, etc. have been proposed. The system program in Patent Document 1 uses coordinate data specified by input operations on a design drawing created as CAD data to calculate the number of parts required for cost estimation, and prepares estimates, cost statements, etc. Suppose you want to automatically create construction-related documents. The creation device/program of Patent Document 2 creates a cost estimate by embedding text data extracted from a design document file and text data in an extracted data file created based on location information into a cost estimate template file specified by customer identification information. It is assumed that a file is created, and then the estimated amount calculated by referring to the cost estimation standard database and unit price database is written into the cost estimate file. The cost estimation device of Patent Document 3 stores data on materials and quantities for each construction item of each facility work in a memory using a design drawing creation means such as CAD, and picks up the quantity of each equipment material using a pick-up means. It is assumed that a totalization table is created by the totalization means, equipment materials are selected and determined from a separately created total comparison table, the total price of each equipment material is calculated, and an estimate table is created.

Patent No. 6293104 JP2008-299541A Japanese Patent Application Publication No. 2002-230082

However, in these conventional cost estimation and estimate creation methods, Patent Documents 1 and 2 only create cost estimation data necessary for facility construction, but do not calculate estimates based on the cost estimation. In Patent Document 3, even if the estimation process is performed after estimation, it is executed by a series of programs, so for example, if different workers perform estimation, estimation, etc. separately, it is necessary to use the same program, etc. . If this is the case, if each person or company uses a separate program to process cost estimates and estimates, it will be difficult to compile them comprehensively. It is not practical in the current situation.

Therefore, the present invention was created in view of the existing circumstances as described above, and when a builder requests various types of equipment work for a building, the person in charge of equipment work presents cost estimates and estimates. In this case, for example, we request and instruct a specialized cost estimation office etc. to carry out an estimate of the necessary equipment materials, etc., and also request and instruct multiple agents/manufacturers etc. to estimate the equipment materials etc. based on the estimate data. When creating a predetermined cost estimate based on the cost estimate data and quotation data from the cost estimate office, the facility construction staff does not have to re-enter the cost estimate data from the cost estimate office or the quotation data from agents, manufacturers, etc. , a method for creating a cost estimate for facility work that can be easily created using these various data, and a cost estimate for facility work that can be presented to the constructor as an appropriate estimated price by comparing estimated prices. The purpose is to provide a creation support device.

A flag as "completed" is also displayed in the status column of the quotation request list 173 displayed on the quotation request screen 170 (estimate step 9/ES9).

(Confirmation of quotation details from equipment construction company)
In the property list 111 displayed on the equipment construction person's terminal 10, for the construction property for which the estimate has been notified, the "completed" flag is displayed in the status column of the quotation requesting list 173, as described above. '' button, the estimate data that is the contents of the estimate can be confirmed by the estimate receiving means 18 (estimate step 10/ES10).

Note that estimates of equipment construction costs based on cost estimation data are normally requested from multiple agencies, so the estimate data is uploaded separately from multiple agencies using the estimator's terminal 30. As shown in FIG. 25, the equipment construction company reviews and organizes several types of estimate data for each type on the construction estimate work screen 1030 displayed on the terminal 10 on the equipment construction person's side so that they can be compared and contrasted. , a matching process between them, and a process of linking related equipment materials, etc. are performed. On the screen of the equipment construction worker's terminal 10 during these processing operations, if there is any corresponding data, discrepancies in input for each item, etc., attention is called by changing the background color, etc. ing.

In addition, when an agency, etc. performs estimation work, each agency may account for the component parts of the same equipment materials, etc. all at once, or separate the component parts into, for example, the main body part and attached parts. In response to this, these items are organized and displayed in a unified manner. As shown in FIG. 25, an equipment material classification display table 1031 is displayed on the construction estimate work screen 1030 of the equipment construction person's terminal 10. In this equipment material classification display table 1031, for example, "classification" is displayed for each equipment material. , "Construction item name", "Inquiry symbol", "Product number", "Product name", "Quantity" and other columns are provided, and an update button 1032 to confirm after performing necessary correction work is also provided. There is. Then, in the classification field, for example, "book" is displayed for the main body part, and "attached" is displayed for the attached part, as an additional note for each row of material data such as equipment materials. When the equipment is separated into two parts, the attached parts are displayed on the next line according to the main part of the equipment and materials. After such inquiries and corrections are made, by clicking the update button 1032, the data is saved as quotation data for each agency, etc. (Step 10/S10).

In the equipment material classification display table 1031, if there are rows with the same reference code, product number, product name, unit, unit price, grade, and notes in the same item in the item list display quotation data, a confirmation message will be displayed. In addition, a processing interruption message is displayed when the same inquiry symbol continues to be repeated, and predetermined work processing such as confirmation and correction is performed.

In addition, when the equipment construction company requests re-uploading for corrections, reviews, etc. to the agency, etc., the information is displayed on the quotation request screen 170 shown in FIG. 12 on the equipment construction person's terminal 10. The "approval" flag that was once displayed in the update column of the quotation requesting list 173 is changed and a "return" flag is displayed. By clicking this "Return" button, you confirm that you want to restore the data, and by performing the update process, the "Working" flag is updated and displayed in the status column. This re-review request is notified to the relevant agency, etc., the revised quotation data is uploaded again, and upon approval, a notification is displayed on the terminal 30 of the person in charge of estimating at the agency, etc. The request for quotation and receipt processing is completed.

(Comparison of quotation items in quotation data from agencies, etc.)
In order to ensure that the cost estimate presented to the contractor by an equipment construction company reflects an appropriate price, the estimated amount corresponding to equipment materials, etc. is discarded from each estimate data notified from multiple agencies, etc. Create by selecting. When creating quotation data from agencies, etc., items and other factors often differ between agencies, making it difficult to simply list them and compare them. Therefore, before comparing and contrasting the estimate data notified from agencies etc. in a list, work items are assigned by checking on the equipment construction worker side terminal 10 whether or not there is an estimate item corresponding to the estimate item. A matching process is performed as follows (Step 11/S11).

In order to perform the comparison process, the quotation data presented by the agencies, etc. is displayed in a list, and the comparison process is performed on the quotation data from the agencies, etc. that have not been subjected to the comparison process. Here, in the property list 111 displayed on the property list screen 110 on the equipment construction person's terminal 10, the status column displays the "Estimate" flag indicating that the estimate data has been notified. (See FIG. 4) By clicking the "ratio" button in the work instruction area 102 of the construction object work screen 100 by the estimate comparison means 19, an estimate comparison screen 1040 is displayed as shown in FIG.

On this estimate comparison screen 1040, a comparison agency list 1041 is prepared in which agencies etc. to which estimate data has been notified are listed. In this comparison agency list 1041, "Operation" displays the display operation for quotation comparison, "Journal classification" displays the journal classification, and "Agency manufacturer" displays the agency that presented the quotation data. ", "Item Match" to display the presence or absence of reconciliation processing, "List Price Total" to display the total of the list price of the estimate, "Grade Input" to display the presence or absence of grade input, "Multiplication Rate" to display the multiplication rate, proxy "Submitted amount" to display the amount offered by the store, etc., "Accepted/Not adopted" to display the acceptance or rejection of the quotation, "Select product name, etc." to enter a check mark when selecting the product name, etc. described later, and correction of material data, etc. There are columns for ``exclusive control'' that displays whether or not restrictions are possible, such as ``exclusive control,'' and ``return previous settings'' that temporarily return updated work contents during assigned work, which will be described later, to the previous work state. Further, on this estimate comparison screen 1040, a CSV button 1042 for specifying CSV data, and a product name selection process button 1043 are arranged.

In this comparative agency list 1041, if the quotation data of an agency, etc. that has not been matched is displayed in the item matching column, a "not done" flag is displayed, so click the "not done" button. By clicking , an item matching screen 1050 shown in FIG. 27 is displayed.

The matching item reservation table 1051 displayed on this item matching screen 1050 is used to allocate the item names of the cost estimation data of the cost estimation office and the items imported from the estimate data of the agency, etc. , "Item number" for the construction item number in the estimate data, "Item name" for the construction item name, and "Area selection" for the construction item name described in the estimate data. Even if the item name used in the cost estimate data (for example, lighting equipment equipment work) and the name used to display the construction item used in the estimate data (for example, [General Lighting]) do not correspond, the name of the item used in the cost estimate data Automatic judgment is made based on a combination of the character match rate in the expression with the estimate data and the history of item matching linked with past properties in past cases, so that they are displayed in a list on the same line. I have to. If there is no construction item corresponding to that item name, a warning message will be displayed.

In this way, even if the names are different, by displaying the name of the item of the estimate data that corresponds to the item name of the cost estimate data, it can be confirmed that quotation data corresponding to the cost estimate data exists, and the item matching screen 1050 is displayed. The arranged execution button 1052 is clicked. Note that the estimate item names in the area selection field can also be entered manually, and if they match, automatic assignment is possible. After checking, the item information of the cost data is added to the estimate data, the cost data is compared with the reference symbol, and the linked data is saved.

(Linking process at equipment construction company)
Even if the comparison work is performed by operating the equipment construction worker's terminal 10, if there is quotation data from an agency etc. that does not correspond to the quotation item in the quotation data that corresponds to the quotation item in the quotation data, the quotation item A linking process for associating each one is performed (step 12/S12).

By clicking the "Display Comparison Table" button displayed in the operation column of the comparison agency list 1041 displayed on the quotation comparison screen 1040 shown in FIG. As shown, an estimate comparison table 1044 by agency, etc. is displayed. In addition to this quotation comparison table 1044, "CSV", "Agent Manufacturer Selection", "Recruitment Data Update", "Unallocated Data Display", and "Allocation Data Update" are provided to instruct each task associated with quotation comparison. An estimate comparison work instruction area 1045 in which each button is arranged is also displayed in sections.

Furthermore, as shown in FIG. 29, at the bottom of the estimate comparison table 1044, by clicking the "Display unallocated data" button in the estimate comparison work instruction area 1045, an unallocated data list 1046 is also displayed on the same screen. A data reflection instruction area 1047 is partitioned between the estimate comparison table 1044 and the unallocated data list 1046. In this data reflection instruction area 1047, "Reflect" is used to reflect the unallocated data in the quotation comparison table 1044, "Cancellation" is used to cancel the previously reflected data, and "Cancellation" is used to add new data. "New" buttons are arranged, along with arrows indicating the direction of reflection/cancellation.

The quotation comparison table 1044 includes "Adopt" to enter a check mark if the quotation is accepted, "Agent Manufacturer" to display the agency that submitted the quotation, "Product Name" to display the product name of equipment materials, etc. "Specifications" to display the specifications, "Inquiry symbol" for the reference symbol, "Supply classification" to display whether it is a new installation or a supplied product, "Quantity", "Unit", "Unit price", "Total list price", "Grade" ”, “Notes” and other columns are provided. The display contents of each of these columns are based on various data obtained by checking and organizing material estimate data lines in a general-purpose data format that have been uploaded and downloaded from an agency or the like.

In the unallocated data list 1046, select "Select", "Category", "Product name", "Specification", and "Enter a check mark to reflect the quotation data in the unassigned data list 1046 in the quotation comparison table 1044". Other columns are provided such as "Inquiry code", "Quantity", "Original quantity", "Unit", "Unit price", "Amount", "Grade", "Remarks...".

In addition, in the quotation comparison table 1044, the agencies, etc. that have submitted quotations are listed sequentially along the row direction, for example, for each product name of equipment materials, etc., for which the quotation price has been presented, and the agencies, etc. are displayed for each product name. This allows you to compare and contrast the estimated amounts presented to you. Note that the list may be displayed sequentially along the column direction, and these display methods can be selected arbitrarily. When displaying along the column direction, a specific agency, etc. is displayed together in a predetermined number of column groups, and material names, quantities, and other necessary data are displayed in column groups. It is displayed in each column inside.

In this quotation comparison table 1044, if there is a product name, material, etc. whose quantity is "0" in the quantity column, it indicates that it is not associated with the quotation data of the agency, etc., and this row is selected. or the "Display Unallocated Data" button in the estimate comparison work instruction area 1045, as described above, a list of unallocated data is displayed.

Then, select it by entering a check mark in the selection field of the material data row of the product name and material you want to allocate in the unallocated data list 1046, and click the "Reflect" button in the data reflection instruction area 1047 to display the quotation comparison table. The data is reflected in the corresponding row 1044 and deleted from the unallocated data list 1046. Note that when the "Cancel" button is clicked, the display of the corresponding row is restored to its original state, and in any case, the data with which the association has been linked becomes usable.

When the quantity in the unallocated data list 1046 and the quantity in the estimate comparison table 1044 do not match with respect to the estimated and estimated equipment materials, etc., the required quantity is allocated. For example, if the estimated quantity based on estimate data from an agency or the like exceeds the estimated quantity based on the estimate data from the cost estimation office, a confirmation message screen will be displayed as a dialog. Although not shown in the diagram, in this displayed dialog screen, if you want to allocate only the cumulative quantity and leave the remaining quantity unallocated, select "Allocate cumulative quantity" or select "Allocate cumulative quantity" to allocate all quantities beyond the cumulative quantity. There are two display buttons: ``Allocate all agency quantities'' if you want to allocate, and ``Allocate any quantity'' if you want to allocate freely even though a confirmation message is displayed.Click to select one of these buttons. do.

In the estimate comparison table 1044, the allocated quantity is entered and displayed, and in the unallocated data list 1046, the allocated quantity is subtracted and displayed. If there is no unallocated quantity remaining, the corresponding row of unallocated data is If the amount is deleted and an unallocated amount remains, the subtracted remaining amount is displayed. Note that the unallocated data list 1046 has columns for "Quantity" that displays the assigned quantity and "Original Quantity" that displays the quantity before assignment. This allows for comparison with the allocated quantity.

Various data such as product names that are not included in the estimate data from the estimate office but are included in the estimate data of the agency, etc. are added to the list of estimate comparison table 1044 as "new". At the time of this addition, for example, it is added to the bottom row of the estimate comparison table 1044, and after the addition, it is deleted from the unallocated data list 1046, and after processing these, for example, the related equipment materials are sorted by reference symbol. It is possible to display and confirm the data such as.

In relation to this new addition process, if there is a main body part or an attached part depending on the equipment material, etc., the materials/parts etc. whose classification display is "attached", which is the attached part, can be added as "new" in the same way. It is set as. Adding and processing such attached parts as new is because even if equipment materials, etc. are displayed as one component in the cost estimate data, they are displayed separately as the main body part and the attached part, even though they are the same equipment material in the estimate data. This is because there may be cases where there are differences in handling, and we are trying to accommodate these differences in handling.

In addition, in the process of allocating unallocated data like this, when the data of the main body part such as equipment materials is displayed in one line, if multiple selections of the main body part are specified, only one line can be selected. A confirmation message screen will be displayed. Also, if you select and specify duplicates, a confirmation message that they have already been assigned will be displayed in the same way.

If, for example, the classification contents are modified in the quotation data during such linking work, the linked equipment materials, etc. will be canceled, and to avoid this, the quote comparison screen 1040 shown in FIG. In the comparison agency list 1041 that is displayed, the work details can be restored by clicking the "Execute" button displayed in the "Return previous settings" column provided in the material data row. . After correcting the necessary parts in the estimate comparison table 1044 and the unallocated data list 1046 due to the returned work, the user clicks on the "Update" button. Then, by clicking the "Completed" button in the item matching field in the comparison agency list 1041, the item matching process is performed again, and the linked content is canceled by this item matching process, and the quantity is changed in the estimate comparison table 1044. ``0'' is displayed in the field, and by clicking the ``Execute'' button to restore the previous settings, the process returns to the state in progress.

Then, by clicking the "Update Allocation Data" button displayed in the estimate comparison work instruction area 1045 on the estimate comparison screen 1040 (see FIG. 28), the data is updated with data that reflects the state at the stage when each task is completed. , this update is reflected and displayed in the accumulated total column of the comparison agency list 1041 (see FIG. 26).

(Creation of grade list at equipment construction company)
When preparing an actual estimate at an equipment construction company, it is extremely rare for each equipment and material delivered from an agent etc. to be delivered according to the list price, and in most cases it is based on the actual selling price. Further, since the actual selling price is usually calculated by a multiplier (grade) on the list price, this grade is taken into consideration when calculating the estimated price at the terminal 10 on the equipment construction staff side.

By clicking the "Not entered" button displayed in the grade input field in the comparison agency list 1041 displayed on the quotation comparison screen 1040 shown in FIG. A grade list display screen 1060 for group setting is displayed (step 13/S13). This grade list display screen 1060 includes a work instruction area 1061 in which buttons such as "Return to estimate comparison" and "Next" are arranged, as well as "Total list price", "Total recruitment", "Difference amount", etc. after calculation. The displayed employment estimate amount display area 1062 is displayed in sections.
