Description

  The present invention can conclude a contract with a contractor and determine the amount of work after the construction while judging the appropriate amount of money for the quality requested by the orderer, even if the specialist knowledge about the construction work is scarce. The present invention relates to a possible construction cost display system.

  In construction work, the purpose of the client is to procure cheap and good items. However, since the orderer lacks specialized knowledge regarding construction work, the orderer cannot determine an appropriate construction cost for the quality required by the orderer. In other words, it can be said that the orderer does not have a standard for selecting an appropriate contractor. For this reason, the orderer often requests quotations from a plurality of contractors and concludes a contract with the contractor who presents the cheapest construction amount.

  When placing an order for the construction in this way, the orderer pays the construction amount estimated by the contractor for each type of construction (the total amount obtained by adding the contractor's profit amount to the “construction cost amount”) before starting the construction. I agree to the agreement. This “cost of construction” refers to subcontract ordering costs, material purchase costs and management costs. However, since the “construction cost amount” after the start of construction is generally closed by the contractor, the “construction cost amount” paid by the contractor to each subcontractor cannot be known.

On the other hand, Patent Document 1 describes a proposal related to a contractor confirmation system and an offer execution system. However, the system disclosed in Patent Document 1 is a technique for confirming whether a requester is a contractor or not by a predetermined organization such as a bank, when there is a request for transferring funds by telephone or the like. This is a technology for executing proposals for funds transfer, etc. using public lines.
Japanese Patent No. 3418499

  In a conventional construction order, the “cost of construction” after the start of construction is generally closed by the contractor, so the orderer knows the “cost of construction” and “the profit of the contractor”. I can't. As a result, it became difficult for the orderer to judge the validity of the “construction amount” paid by himself.

  On the other hand, in the system described in Patent Document 1, it is possible to confirm whether or not the applicant is a contractor or to make a request for funds transfer using a public line or the like. It is impossible to know the validity of the “construction amount”, that is, the “construction cost amount” and the “contractor's profit amount”.

  Therefore, the present invention was created to solve the above-mentioned problems. The breakdown of all “construction amount” managed by the contractor, such as “construction cost amount” and “contractor's profit amount”, is provided on the Internet. The purpose is to provide a construction cost display system that can be confirmed on the side of the orderer using, and can guarantee the validity of the “construction amount” at the time of contract.

According to the first means of the present invention, from each terminal 10 arranged in an orderer who orders a construction work, a contractor who undertakes the construction work, and an audit corporation which audits the construction cost of the contractor, the web server 20 A system for displaying input construction costs,
The information identifier, information title, and information message data of various information data input from each terminal 10 are recorded in the information data of the information data storage unit in the Web server 20, and the input image data The Web server 20 is provided with a document management program 21 provided to record the title, image message, and captured image data in the image data storage unit, and each data based on the information category transmitted from each terminal 10 Are configured to automatically sort and store them on a web server,
An estimate input means 100 for inputting the construction cost presented by the subcontractor from the contractor's terminal 10 and the document management program 21 storing it in the Web server 20 as estimate information;
When the order information ordered from the subcontractor is input from the contractor's terminal 10 and the document management program 21 saves it in the Web server 20 and updates the information, the updated data is registered while retaining the original data. Purchase order input means 200 for
A volume assessment record input means 300 for inputting the volume assessment record of the ordered work from the contractor's terminal 10 as the volume assessment information and storing it in the Web server 20 by the document management program 21;
A document image input means 400 in which the document management program 21 stores data input from the contractor's terminal 10 as document image information, such as invoices and slips issued from the subcontractor to the contractor, in the Web server 20;
Information such as invoices and slips input as the form image information is displayed on the terminal 10 of the audit corporation, and the invoices and slips of the subcontractor are displayed in the form in the Web server 20 by the audit of the audit corporation. It is configured to collate with image information .

As in claim 1 of the present invention, when the order information ordered from the subcontractor is input from the contractor's terminal 10 and the document management program 21 stores it in the Web server 20 and updates the information, the basic data is stored. It has a purchase order input means 200 for registering updated data while holding it, and each terminal 10 of the orderer and the audit corporation receives estimate information, order information, volume assessment information, and form image information in the Web server. An information display means for displaying is provided so that the form image information in the Web server 20 can be collated with the original of the subcontractor's invoice, slip, etc. so that the contractor can actually create and The breakdown of all construction costs managed by the contractor, such as the forms used (contract breakdown, order breakdown, invoice), etc. can be disclosed to the orderer and supervisor using the Internet, etc. . In other words, the “construction amount” at the time of contract and the “construction cost amount” after the start of construction can be verified for each breakdown of “by construction type and material” instead of “total amount”. ”And“ contractor's profit ”can be used to ensure the validity of the“ construction amount ”. It is also possible to check the information of “construction amount” and “construction cost” for each work type and material at any stage of the business flow between the orderer, contractor and audit corporation. Is possible.
In addition, the form image input means 400 displays information such as invoices and slips inputted as form image information on the terminal 10 of the audit corporation, and the invoices of the subcontractor through periodic audits of the audit corporation. Since the original of the slip or the like is checked and checked against the form image information in the Web server 20, it can be confirmed that the information of the “construction cost amount” to be shared matches the actual “construction cost amount”. It becomes possible to determine whether the cost is appropriate. As a result, when it is determined that the “construction amount” consisting of “construction cost amount” and “contractor's profit amount” is appropriate, the audit corporation issues an audit report to the orderer, etc. It can be proved that the construction of was carried out at a reasonable price.

In addition , it is possible to input purchase negotiation results with a plurality of subcontractors at the terminal 10 of the contractor based on the estimate information of the estimate sheet input means 100 , and the contractor can obtain order information of better conditions until it is obtained. It can be updated at any time. As a result, the orderer can select the estimate information close to the desired condition. Moreover, since the estimate information until the orderer selects can be confirmed from the terminal 10 of the audit corporation, it is confirmed based on the estimate information in the Web server 20 whether the pre-contract estimate and order contents are appropriate. be able to.

In addition, more volume assessment written statement input means 300, because the contractors on the basis of volume assessment information is input at terminal 10 of the Contractor's payment information paid to subcontractors, the progress of the construction work and the "construction costs amount" It can be accurately grasped.

  As described above, according to the present invention, a breakdown of all “construction amount” managed by the contractor, such as “construction cost amount” and “contractor profit amount”, is confirmed on the orderer side using the Internet or the like. It is possible to provide a construction cost display system that can guarantee the validity of the “construction amount” at the time of contract.

  In the best mode of the present invention, a terminal 10 having a Web browser is arranged in an orderer who orders a construction work, a contractor who undertakes the construction work, and an audit corporation which audits the construction cost of the contractor. The web server 20 includes a document management program 21 having a web dub function. The contractor uses the document management program 21 to input estimate information 100 for inputting estimate information between the contractor and the subcontractor, and the orderer selects the subcontractor from the estimate information and places an order with the subcontractor. A purchase order input means 200 for inputting the ordered order information; a volume assessment record input means 300 for inputting monthly volume assessment information created based on the order information; an invoice issued from the subcontractor to the contractor; A form image input unit 400 for inputting a slip or the like as form image information is input to the Web server 20. On the other hand, each terminal 10 of the orderer and the audit corporation is provided with information display means for displaying estimate information, order information, volume assessment information, and form image information in the Web server 20 input by the contractor. In the estimate input means 100, the ordering information is input by the contractor's terminal 10 with the contractor selected by the contractor and the estimated amount from the estimates presented to the contractor by a plurality of subcontractors. In the volume assessment record input means 300, the payment information paid by the contractor to the subcontractor based on the volume assessment information is inputted at the terminal 10 of the contractor. In the form image input means 400, information such as invoices and slips input as form image information is displayed on the terminal 10 of the audit corporation, and the invoice of the subcontractor is regularly audited by the audit corporation. The original purpose such as a slip is confirmed and collated with the form image information in the Web server 20 to determine the suitability of the construction cost, thereby achieving the original purpose.

  The system of the present invention is a system in which an orderer, a contractor, and an audit corporation display a construction cost input from their terminal 10 into the Web server 20, and “construction amount” of “construction amount” spent on the construction is displayed. This is a system in which the orderer and the audit corporation can objectively judge whether the “cost” and “contractor's profit” are appropriate (see FIG. 1).

  The orderer is the person who orders the work, the contractor is the person who undertakes the work, and the audit corporation audits the work cost of the contractor. The contractor has a relationship of supervising and executing the construction using a plurality of subcontractors, and the “construction cost” and “contractor's profit” of the “construction amount” are stored in the Web server 20 from the terminal 10. input. Therefore, the web server 20 is provided with a document management program 21 having a web dub function. The contractor sequentially inputs various kinds of information into the Web server 20 via the estimate document input unit 100, the volume assessment record input unit 300, and the form image input unit 400 by the document management program 21 (FIG. 2). reference).

  The estimate input means 100 is means for inputting estimate information between the contractor and the subcontractor. The estimate information is obtained by sequentially inputting purchase negotiation results with a plurality of subcontractors. Then, the contractor selects the most appropriate estimate from the estimate information and presents it as a separate estimate to the orderer. In this estimate, the unit price and the amount presented by the subcontractor are entered as “construction cost amount”.

  The purchase order input means 200 inputs the order information ordered by the contractor to the subcontractor selected by the orderer based on the estimate. In this case, the contractor continues to negotiate the price with the subcontractor to which the contract is made, and inputs the actual order amount. In addition, since the construction cost amount of the construction is determined at the time of placing an order with the subcontractor, the specification, quantity, unit price, amount, etc. are entered in detail as the ordering information. From then on, ordering information generated during construction is sequentially input. At this time, when the information is updated, the updated data can be registered while maintaining the original data. By doing so, since the history of all data remains, even if the data content is falsified, the original data before falsification can be confirmed.

  The volume assessment record input means 300 inputs the monthly volume assessment information created based on the order information. The volume assessment information is for inputting a volume assessment record created by the contractor performing a monthly assessment of the ordered work, and the contractor pays the subcontractor every month based on the volume assessment record. Accordingly, the volume assessment information includes payment information paid by the contractor to the subcontractor. Further, the input of the volume assessment information is accompanied by the input of a bill from a subcontractor. The following form image input means 400 is used for these inputs.

  In other words, the form image input means 400 inputs invoices, slips, etc. issued from subcontractors to contractors as form image information. Therefore, together with the volume assessment record input means 300 for inputting the volume assessment information, the form image input means 400 can leave an invoice from the subcontractor as an image.

On the other hand, each terminal 10 of the orderer and the audit corporation has information display means for displaying estimate information, order information, volume assessment information, and form image information in the Web server 20 input by the contractor. The orderer and the audit corporation can always check various information in the Web server 20 such as ordering information during construction, volume assessment information, and payment information by this information display means (see FIG. 3).

  The contractor is regularly audited by an audit corporation. At this time, the original slips and forms that are actually exchanged between the contractor and the subcontractor are confirmed, and it is confirmed that there is no difference between the various information entered in the Web server 20. . That is, in the form image input means 400, information such as invoices and slips input as form image information is displayed on the terminal 10 of the audit corporation, and the originals such as invoices and slips of the subcontractor are confirmed and Web The form image information in the server 20 is collated to determine whether the construction cost is appropriate. As a result of the audit, if the on-site cost management is appropriate, the audit corporation issues an audit report to the orderer.

  The terminal 10 possessed by the orderer, contractor, or audit corporation includes a web browser that accesses the Internet using a computer terminal, a mobile phone, and the like. Connecting. On the other hand, the Web server 20 is provided with a document management program 21 for checking a user identifier and a password and sharing information between registered members (see FIG. 1). In the document management program 21, the image data obtained by directly inputting from the terminal 10 and the actual slip read by the scanner and the image data are listed.

In the document management program 21, the information identifier, information title, and information message data of various information data input from the terminal 10 are recorded in the information data of the information data storage section in the Web server 20. Further, the document management program 21 records the image title, image message, and captured image data in the image data storage unit for the image data. In this way, the document management program 21 of the Web server 20 automatically sorts and stores data based on the information category transmitted from the terminal 10.

The contractor operates the document management program 21 of the Web server 20 from the terminal 10 to create a document based on various information. For this reason, the document management program 21 has a Web dub function. The Web dub (WebDAV) function refers to an international standard protocol that extends HTTP used for file transfer on the WWW and manages files and folders on a Web server from a Web browser of a client. By providing the document management program 21 with the Web dub function, the document management program 21 of the Web server 20 can be freely accessed from the terminal 10 of the orderer or audit corporation. As a typical example of the document management program, it is preferable to use “Autodesk Buzzsaw (registered trademark)” manufactured by Autodisk Corporation of the United States. According to this document management program, report data information can be uploaded in, for example, PDF or JPG format as well as text format. Moreover, it is possible to automatically sort by folder and file based on the information category. Therefore, it is more suitable for handling data with an image.

  In order to output various types of information from the Web server 20 by the information display means possessed by the orderer and the audit corporation, the Web server 20 is accessed from the terminal 10 such as a portable terminal or a computer terminal. At this time, data regarding the user identifier and password of the user of the terminal 10 is transmitted to the Web server 20. The Web server 20 confirms the document output authority based on the received data. When the output authority can be confirmed, a list of information that can be output with the authority is displayed on the terminal 10 and output by a printer or the like.

  In addition, based on various information in the Web server 20, for example, estimate information, order information, volume assessment information, and form image information can be made into predetermined documents. The orderer and the audit corporation can easily know the validity of the “construction amount”, that is, the “construction cost amount” and the “contractor's profit amount” by always checking the information converted into these documents. Is possible.
