Description

  The present invention relates to a volume payment calculation device for building work.

  As for construction contract work, it is common practice to pay a part of the price to the construction contractor as a deposit or an intermediate money before handing over to the owner of the building. Such customs are recognized as a bridge between the contractor's delivery of the building, but in recent years, the contractor has gone bankrupt after the client has overpaid the intermediate money, etc. As a result, there is a problem that many owners are greatly damaged.

  This problem can be prevented by the client paying the volume, and what is described in Patent Document 1 has been known as a method for calculating such a volume payment. In this conventional example, a payment system for a custom house includes a plurality of stages of preset progress of construction such as foundation work and building work, and a contract content storage unit for storing the price of each stage, and a construction In response to a payment request corresponding to the stage of construction from a contractor terminal, a survey instruction section for transmitting a survey instruction to the survey terminal as to whether the progress of the construction has reached the above stage, and from the survey terminal to the Internet When the survey result indicating that the construction has reached the above stage is input via the payment, the payment amount corresponding to the stage is read from the contract content storage unit and the payment instruction is transmitted to the financial institution terminal so as to pay the contractor. And an instruction unit.

JP 2001-331738 A

  However, the above-mentioned volume payment has a drawback that it is not possible to substantially prevent overpayment to a construction contractor.

  In other words, a set of construction work such as construction of a custom house is generally performed by a construction contractor such as a construction shop using an outside contractor such as a carpenter or a material maker. Part of the construction contract price paid to the contractor will be allocated indirectly through the construction contractor. In other words, the cost to the material manufacturer, which can be said to be borne by the owner, is actually paid from the owner to the construction contractor. For example, in general, there is a payment grace period called a so-called payment site for payment from a construction contractor to a material manufacturer, etc. Therefore, during this grace period, the construction contractor is substantially excessive from the owner. You can see that you are paid.

  Substantial overpayment to the construction contractor in this sense can be prevented, for example, if the owner directly contracts with the material manufacturer and pays the price directly. As a result, the client is likely to be burdened with a greater burden than before, such as requiring complicated knowledge and various manpowers.

  The present invention has been made to eliminate the above-mentioned drawbacks, and it is possible to effectively calculate the amount of payment for construction work that can effectively prevent substantial overpayment to a construction contractor without increasing the burden on the owner. The purpose is to provide a device.

  In addition, another object of the present invention is to provide a construction work volume payment calculation method and a construction work volume payment that can effectively prevent substantial overpayment to a construction contractor without increasing the burden on the owner. To provide a calculation system.

According to the present invention, the object is
The primary contractor's unique cost and the external contractor's cost included in the contractor's compensation for the complete set of construction work are associated with each of the preset partial works of the complete set of the built work, and the external contractor's cost is the contractor. A construction cost database 1 that is stored in association with the payment terms of each outside contractor,
A volume evaluation means 2 that receives a completion report of a specific partial construction through a network from a client terminal and evaluates the original contractor specific cost and the cost for each external contractor corresponding to the partial construction as a volume;
The contractor-specific costs and third-party contractor costs that have been evaluated in terms of volume are aggregated in units of predetermined periods according to the payment terms related to the contractor-specific costs of the main contractor and the third-party contractor-specific payment terms. This is achieved by providing a volume payment calculation device for construction work having client payment calculation means 3 for calculating a volume payment amount for each payment date of the client collectively for each payment date determined.

  According to the present invention, the calculation of the volume payment of the owner is performed not only for the amount but also for the due date, and the cost of the outside contractor as a so-called subcontractor used by the main contractor as a construction contractor is such a main contractor. Will be eligible for volume payments from the client on the due date according to the payment terms for the subcontractors. Therefore, substantial excessive payments to the construction contractor can be prevented.

  In addition, when calculating the volume payment, by using the payment conditions between the main contractor and the outside contractor as described above as they are, it is possible to maintain the conventional contract relationship for the construction contract work as it is. The burden on the client at the time of requesting the construction can be maintained at the same level as before. Furthermore, since it is expected that the primary contractor and the external contractor have a continuous contractual relationship, the payment site for the external contractor of the primary contractor can expect a certain long period of time, and as a result, By postponing the payment of the volume, it is possible to prevent overpayment due to an error in the evaluation of the volume, and it is possible to appropriately secure funds for the bulking work. In addition, in the main contractor such as a construction company, excessive cash inflows due to excessive payables due to payment sites to a large number of external contractors such as material manufacturers and carpenters are eliminated. This makes it easier to grasp the financial situation and prevents the deterioration of cash flow due to losing sight of the balance of business. In addition, since the overpayment to the construction contractor can be effectively prevented as described above, a sense of security equivalent to a so-called completion guarantee can be given to the client.

  In the above-mentioned construction work volume payment calculation device, the construction cost database 1 is arranged for the contractor, etc., supervision, etc. for the main contract fee as a price of the construction shop etc. for the construction work of the custom house as a set of construction work, etc. It is divided into the contractor's own expenses as expenses for its own labor, etc., and the expenses for each external contractor as materials and construction labor costs for each external contractor such as material manufacturers and carpenters, etc. Memorize payment terms for each subcontractor. The payment conditions are, for example, cash payments 60 days after the end of the month for material manufacturers, cash payments for the carpenter 5 days after the end of the month, or cash payments for carpenters at the end of the 25th day. Can consist of a period up to the payment date.

  In addition, the construction cost database 1 stores a set of construction works for each partial construction. Each partial construction can be configured as, for example, roof construction, exterior wall construction, or temporary toilet installation, etc., but it can also be constructed as an assembly work for the material in units of materials used for the construction. . That is, for example, in carpentry work, assembly work in units of pillars can be configured as partial works.

In this way, when constructing partial construction by material unit,
For each partial construction, storage means 8 for storing a unit prime contractor-specific cost and a unit-specific contractor-specific cost set in advance corresponding to the material used in the partial construction;
Input means 4 capable of inputting architectural CAD data;
The material included in the CAD data for building input from the input means 4 and the quantity thereof are extracted, and the above-mentioned main contractor specific compensation and the external according to the CAD data for building based on the above-mentioned unit contractor specific cost and unit external contractor cost By using the computer having the calculation means 9 for generating the trader-specific costs, it is possible to easily extract the partial construction according to the CAD data for construction. For example, in the case of the above-mentioned pillar, the purchase price of one pillar from a wood maker or the assembly work price of one pillar by a carpenter can be investigated and set in advance, and it can be set as a cost by unit external contractor, In addition, a predetermined ratio of the cost for each unit external contractor can be set as a unit contractor-specific cost such as a fee for arranging a material maker or a carpenter of a construction shop. In this case, it is also possible to construct a server / client system by configuring a computer equipped with the storage means 8 and the like as a client computer as will be described later.

  Further, for example, when the volume evaluation means 2 receives a completion report of a specific partial work from a client terminal by mail, the partial volume evaluation means 2 evaluates the partial work as a volume. When a completion report is transmitted from the client terminal, it is sufficient to specify a partial construction, and a code corresponding to the specific partial construction can be transmitted. In this case, if an image or video showing the completion of the partial construction is taken in advance and the code of the partial construction is transmitted together with this image data or video data, the objective reliability of the completion report can be ensured. it can.

  Further, the client payment calculation means 3 calculates the payment amount of the payment for each payment date of the client. The payment amount of the main contractor and the external contractor is totaled, and the payment conditions for the primary contractor of the contractor and the contractor for each contractor external contractor are calculated. According to the payment conditions, the client's volume payment amount for each payment date is calculated. Specifically, for example, there is a plurality of volumes within the same month for material manufacturer A with a payment condition for cash payment 60 days after the end of the month, and the same for carpenter B with a payment condition for cash payment on the fifth day of the month following the 25th day. Consider a case where there is a single volume within the month (within the payment aggregation period), and there is a plurality of volumes within the same month (within the payment aggregation period) for the construction shop having the same payment conditions as Carpenter B. In this case, at the time when the closing date for each is passed, for each of the material manufacturer A and the construction company with multiple volumes, the amount of the volume in the month (within the payment aggregation period) is aggregated, and the payment due date is For the material manufacturer A that does not match the others, the amount of the volume collected as described above is the payment made by the owner whose payment date is 60 days after the closing date. On the other hand, The amount of the combined volume of the single volume of the carpenter B and the volume totalized as described above for the construction company B is the payment amount of the client whose payment date is 5 days after the closing part.

  Therefore, according to the present invention, the unique expenses for each of the main contractor and each external contractor are aggregated for each due date based on the payment conditions from the owner to the main contractor and the payment conditions from the main contractor to each external contractor. Is calculated as the client's volume payment amount for each payment date, the client has a direct relationship with the outside contractor only at the time of payment, and this does not increase the substantial burden on the client. Substantial overpayment can be prevented.

In addition, when the owner actually pays the cost to an outside contractor who does not have a direct contract relationship,
Having an input means 4 for receiving an input of an expense request associated with the completed partial construction in units of the predetermined period from the outside contractor to the main contractor;
The client payment calculation means 3 compares the external contractor cost evaluated for the volume and the corresponding partial construction with the above-mentioned cost claim and the corresponding partial construction. If the volume payment calculation device is configured with the matching unit 5 for determining the matching external company cost as the client's volume payment amount, unnecessary overpayment to the external company is ensured by ensuring consistency with the bill from the payee. Can be prevented.

In addition, it has a process database 6 that stores and stores the partial work in the construction schedule of the complete set of construction work,
The client payment calculation means 3 refers to the process database 6 and accumulates the contractor-specific costs corresponding to the partial works allocated to the schedule up to the client's due date and the costs for each external contractor to estimate the payer's due date. If the above-mentioned volume payment calculation device is configured with the forecast evaluation unit 7 for calculating the asset evaluation, an asset-like evaluation can be calculated for the construction work on the actual payment date of the volume payment. Instant asset valuation forecasts can be obtained and based on this, confirmation can be made that overpayment is prevented. In addition, the actual accounts payable at the due date can be grasped by comparing the asset value evaluation forecast and the cumulative value of the volume payment until the due date.

The calculation of the volume payment for building construction described above is
In the volume payment calculation server provided with the construction cost database 1 capable of storing the construction contract work in association with each of the partial constructions divided into a plurality of preset construction works,

  In this embodiment, the volume evaluation system constitutes a part of the transaction system shown in FIG. This transaction system is a third party management for contractors who have contracts with the owners of building contracts, as the management headquarters concludes an escrow contract with the building headquarters as the escrow fund from the client who is the customer of the home building. The headquarters pays the volume of the housing to the client. For example, an organization such as a construction company or a real estate company serves as the administrative headquarters, and by signing a lease contract for the above-mentioned volume evaluation system with this administrative headquarters, the construction company becomes a member of the system and the construction work from the administrative headquarters Get paid for the volume.

  As shown in FIG. 1 (b), the member contractor, after explaining the above transaction system, concludes a contract with the owner and builds materials purchased from material manufacturers such as lumber shops, sash makers, and system kitchen makers. Carry out home construction using contractors such as carpenters, electrical stores, and cross (interior) stores. When building a house, member contractors use a personal computer (PC) that they own to estimate with the above-mentioned system for volume evaluation, create an estimate to be submitted to the owner, create an execution budget, create a schedule, etc. Then, estimate data, ordering data such as a construction fee for a contractor and a material fee for a material manufacturer, execution budget data, process data, and the like are transmitted as construction contract data to a server of the management headquarters via a network. The management headquarters server that received the construction contract data negotiates with the financial institution that has entered into an escrow fund loan contract with the client, and receives the building contract price corresponding to the estimated amount from the client as the escrow fund. After that, the PC owned by the owner is informed of the payment by the escrow of the construction funds for the housing construction contracted by the member construction company. In addition, necessary document procedures for escrow contracts will be made separately.

  Further, the computer of the member construction shop orders the building material based on the ordering data of the building contract data to the material manufacturer server. Further, the member contractor signs a contract with a contractor on the premise that the construction completion photograph is taken and transmitted to pay the construction fee based on the order data. It should be noted that in ordering and contracting these, it is agreed as a contract condition that the price is paid by escrow. After that, when the building materials are brought into the site and the construction process proceeds, the contractor uses the camera function of the mobile phone to take a picture of the completed work site, and uses the Internet connection function to make member construction work. The image data is transmitted to the store PC. The PC manager of the member contractor who has received this information indicates which process the image data is on the monitor, whether the work content is as planned, that is, whether the planned work content is satisfied, for example, a design drawing Confirm by comparing with. If there is no problem in the confirmation, the PC administrator designates the corresponding process to the management headquarter server and transfers the image data. The image data is transmitted to the management headquarters by uploading image data to each process in the process chart posted on the construction progress status website operated on the network. By associating the above process data with the update of the process schedule, the progress of the home construction work is grasped as needed.

  In accordance with this progress, the server of the management headquarters makes a payment for the price (cost) included in the ordering data from the escrow fund to the material manufacturer and the cooperating company (outside contractor) by the volume evaluation, The member construction shop pays the volume of the labor cost, etc. included in the execution budget, and the gross profit (property of the main contractor) that is the difference between the estimated amount and the execution budget, based on the volume evaluation. The volume evaluation is reflected on the volume evaluation website operated on the network by the server of the administration headquarters, and the member contractor can grasp the schedule of the volume payment by transferring the update data of the website. it can.

  The construction progress status website is preliminarily set with an authentication code for the member contractor and an authentication code for the owner, and the member contractor uses the self-authentication code to set an address (URL: Uniform) on the network. Use the Resource Locator to access the website and upload the image data. The owner uses the authentication code to access the website using the address on the network and check the progress of the construction using the above image data. Know from time to time. In the above description, a case where a photograph, that is, a still image is posted on the website has been described, but a moving image may be posted.

  The material master file 14 stores names for individually identifying all building materials. For example, structural materials-Akamatsu glulam-beams-105 mm × 105 mm × 3,000 mm (special etc.), etc. Each material is identified by related information such as the type of material or structure material, material type, application, and dimensions. Each material is assigned an ID code such as “0001” or “0002”.

  In the quantity data file 15, the quantity of materials necessary for home construction is stored in one-to-one correspondence with the ID code for each material. This quantity is extracted from the design data created by the building CAD system by a calculation process using the material master file 14 by the material amount extraction calculation unit 31 in the calculation means 9, for example, the name of the material included in the CAD data It is created by acquiring the quantity written together. In the integrated unit price DB 16, the integrated unit price of materials necessary for housing construction is stored in one-to-one correspondence with the ID code for each material. The integrated unit price is set based on, for example, integrated data. The work time DB 17 stores the time required for the construction work of materials necessary for home construction in correspondence with the ID code for each material. The average value of this time is set based on past results and experiences.

  The manufacturer / trader file 18 stores material manufacturers, carpenters, and the like who have transactions by specifying ID information necessary for communication such as their names, names, addresses, and e-mail addresses. Also, an appropriate ID code is assigned to each manufacturer. It is also possible to additionally register and store material manufacturers, carpenters, and the like in the manufacturer / contractor file 18 by the operator of the construction shop using the keyboard or the like constituting the input means 4 '.

  In the execution budget unit price DB 19, the estimated amount of the material maker and the total amount of expenses such as general labor costs and labor costs for carpentry work are paired with the ID code of each material in the material master file 14 described above for each material. Stored in correspondence. The general labor cost of this carpentry work can be determined, for example, by taking the product of the work time for each material in the work time DB 17 and a predetermined number, that is, by applying a predetermined hourly rate corresponding to the work time. It is.

  The estimated amount for each material of the building material manufacturer is stored in the purchase manufacturer file 20 in one-to-one correspondence with the ID code of each material in the material master file 14. For example, the material 0001 is stored from the material manufacturer A at 1,000 yen. The purchase maker file 20 can also store additional registration by input from a keyboard or the like that constitutes the input means 4 ′ in the same manner as the maker / trader file 18 described above.

  In the expense data file 21, expenses such as labor costs are stored for each material in a one-to-one correspondence with the ID code of each material in the material master file 14. This expense can be determined, for example, by setting a predetermined rate in advance for the integrated unit price in the integrated unit price DB 16.

  Therefore, the amount of money in the execution budget unit price DB 19 includes the labor cost of carpentry work that can be calculated from the work time for each material in the work time DB 17, the estimated amount of the purchase maker file 20 corresponding to each material, and the cost corresponding to each material. It is calculated for each material by obtaining the sum of the cost of the data file 21 by the price calculation unit 32 of the calculation means 9.

  The procedure data file 22 stores work procedures for each material, that is, the order. For example, work such as roof construction and outer wall construction is stored along the building process. An appropriate ID code is assigned to each operation. The material procedure data file 23 stores an order indicating the construction procedure in a one-to-one correspondence for each material in the material master file 14. This order is set corresponding to the work of the procedure data file 22. For example, when there are a plurality of materials used for roof construction, the same order is given to the plurality of materials. This order can be changed by an input from a keyboard or the like as the input means 4 ′ by the operator of the construction shop.

  In the total time data file 24, the process time of each material calculated by the quantity data file 15 and the work time DB 17 by the process calculation unit 33 of the calculation means 9 using the ID code of each material of the material master file 14 as a key, A bundle of the aggregate time of materials for each predetermined time generated by sorting according to the procedures of the material procedure data file 23 and allocating the accumulated work time to the predetermined time is one-to-one with the work of the procedure data file 22. It is stored correspondingly. The predetermined time is desirably set to 8 hours, which is a working time per day. Accordingly, the work time of “quantity × unit work time” for each material is totaled for each work procedure and accumulated for each material until the cumulative total of 8 hours, for example, in the first 8 hours. 4 units of material 0001 for a unit work time of 1 hour and 2 materials 0002 of a unit work time of 2 hours are set corresponding to the operation a, and the unit work time 2 is set in the second 8 hours. The time material 0003, one piece corresponding to the operation b, and the unit work time 3 hours, the material 0004, two pieces corresponding to the operation c, etc. are set for a plurality of 8 hours until there are no more materials. A total time data file 24 for each is generated.

  The image data file 25 stores image data received from a carpenter's mobile phone, and an appropriate ID code is stored when a store manager PC stores the image data transmitted from the carpenter's mobile phone through the network. Assigned and stored as image data. The ID code can be automatically assigned by the calculation means 9.

  The execution budget data 26 is created by associating the execution budget unit price in the execution budget unit price DB 19 and the quantity in the quantity data file 15 one by one with the ID code of each material in the material master file 14 as a key, and the price calculation unit 32. After the product corresponding to each material is obtained by the above and the execution budget for each material is generated, the total execution budget is calculated.

  The order data 27 is stored in the manufacturer / trader file 18 by associating the estimated amount of the purchase manufacturer file 20 and the quantity of the quantity data file 15 one by one with the ID code of each material in the material master file 14 as a key. A total is created for each time. Similar to the execution budget data 26, after the product of the estimated amount and quantity corresponding to each material is obtained by the price calculation unit 32, the total order price corresponding to each material manufacturer is distributed and totaled for each material manufacturer. Is calculated. Further, a model of the purchase order is also stored as the order data 27, and a purchase order using the printer as the printing unit 13 for each ordering party using the model by the progression unit 34 of the calculation unit 9. Can be created.

  The schedule data file 28 stores the schedule, and an appropriate ID code is assigned to each schedule along the calendar by using a calendar function installed in the PC. The schedule setting can be adjusted by an operator of the construction shop by inputting to a keyboard or the like as the input means 4 '.

  On the other hand, the volume management server, as shown in FIG. 3 (a), in addition to the files and the like in the various means of the PC of the member builder, the order management unit 38, the builder's A process management unit 39 including a function of the update management unit 36 in the PC, a volume calculation unit (volume evaluation means 2), and a management data creation unit 41 are provided. It should be noted that files having the same data structure as the files in the various means of the PC of the member contractor are denoted by the same reference numerals in FIG.

  The order management unit 38 is used when placing an order with a material manufacturer on-line from the management headquarters instead of FAX from a construction company, as described above, such as a keyboard as an input means 4 (4A) by an operator of the management headquarters. Based on the input from, order data 27 'processed as a purchase order is transmitted to the server of the material manufacturer through the network. The process management unit 39 sequentially confirms update information on the construction progress status website with the image management server via the network. When update or addition of image data is detected, the process management unit 39 acquires the update information and stores it. It is stored in the image data file 25 ″ of 8′A).

  When the volume calculation unit 2 detects the storage of the image data, it searches for the schedule in the schedule data file 28 ′ associated with the image data in the image data file 25 ″ or the work in the procedure data file 22 ′, and supplies the material procedure data. The execution budget and schedule volume are calculated by referring to the file 23 ′, the total time data file 24 ′, the material master file 14 ′, the quantity data file 15 ′, the execution budget unit price DB 19 ′, the purchase manufacturer file 20 ′, etc. The calculation results are stored in the storage means 8 'as the volume data 42 and the schedule volume data 43. The amount volume data 42 and the like specify the name of the material, work, schedule, name of the material manufacturer or carpenter, an image, etc. together with the creation date. Multiple IDs are created cumulatively by specifying the ID code of the loan. As will be described later, transmission of the payment instruction for the volume to the customer is performed, for example, in units of one month, and is performed by the proceeding unit 34 '. It is posted on the volume evaluation website through the network by the output means 11 ′ (11′A).

  The volume evaluation website is operated by the progress unit 34 ′ of the volume management server, and the material master file 14 ′, the quantity data file 15 ′, the purchase for the template of the predetermined process table stored in the management data 44. Process chart generated by writing data using manufacturer file 20 ', expense data file 21', schedule data file 28 ', material procedure data file 23', procedure data file 22 ', image data file 25 ", etc. Each process (work) in this process table has a specific ID code corresponding to a specific material, schedule, name of material manufacturer or carpenter, image, further subdivided process (work), etc. Held points are formed.

  For example, when the progress unit 34 ′ receives an inquiry request including the quantity of the material at the point from the member construction shop that has accessed the volume evaluation website through the network, the progression unit 34 ′ is requested based on the ID code of the point. The material quantity is searched, an HTML file displaying the quantity data is created and transmitted to the client. The PC of the member construction shop displays the contents of each process including the material quantity and the like on the monitor of the display means 12 based on the received HTML file.

  The management data creation unit 41 creates management data 44 when detecting the transmission of the payment instruction. The management data 44 is created in one-to-one correspondence with the monetary volume data 42, and the management headquarters displays it on the monitor as the display means 12 ′ or the printing means 13 ′ according to an instruction from the input means 4A by the operator. It is possible to confirm the payment status of the volume by printing with the printer.

  When the progress unit 34 ′ of the volume management server receives the difference data such as the quantity data file 15, the execution budget unit price DB 19, and the purchase maker file 20 from the PC of the construction shop through the network, the progress management part 34 ′ appropriately performs each construction work of the member construction shop. And the quantity data file 15 ′ and the like are stored together with the ID code. Therefore, as shown in FIG. 3A, the volume management server also has a quantity data file 15 'having the same data structure as that stored in the PC corresponding to each member construction store.

  As shown in FIG. 3B, the image management server includes an input means 4 (4B) for receiving image data from the member builder through the network, an image data file 25 for storing the image data, and the member builder's A storage means 8 ′ (8′B) for storing the procedure data file 22, the schedule data file 28, etc. stored in the storage means 8, and an output means 11 ′ for transmitting the image data to the volume management server via the network. 11′B) and arithmetic means 9 ′ (9′B) for controlling the storage, output and the like. This computing means 9'B also manages and operates the construction progress status website, publishes the process schedule of the member construction shop, and links an ID code such as specific image data to each work of this process chart Let

  That is, when the calculation means 9′B receives an inquiry request for each work from the owner who has accessed the construction progress status website through the network by the input means 4B, the calculation means 9′B displays a screen for inquiry of the work in the process chart including the image data. An HTML file to be generated is created and transmitted to the client by the output means 11′B. The owner's PC displays the contents of each work including image data on the monitor of the input means 4 'based on the received HTML file.

  In the above-described system for evaluating the production volume, the PCs of the member construction companies process and store data as shown in FIG. 4 and communicate with the production volume management server through the network. As shown in FIG. 4, CAD data created by a PC administrator of a member construction company and stored in the PC is a material amount extraction calculation unit 31 from the PC administrator via a keyboard or the like as input means 4 ′. The quantity data is extracted by referring to the material master file 14 and stored in the quantity data file 15 as quantity data corresponding to each material. Further, the integrating unit 35 takes the product of the integrated unit price DB 16 for each material for this quantity data, and performs integration (integration step). It should be noted that, by an input operation from the keyboard or the like as the input means 4 ′ by the operator, the integration result is output to the printer as the printing means 13 and printing is performed as an estimate, or an appropriate rate is added for each material during the integration. It is also possible to perform integration by adding a work rate of a certain rate to the integrated unit price.

  Next, based on the quantity data, the price calculation unit 32 generates execution budget data 26 by referring to the execution budget unit price DB 19 and also generates order data 27 for each material manufacturer by referring to the purchase manufacturer file 20. Is done. The formed execution budget data 26 and order data 27 are transmitted to the volume management server via the output means 11 by the advancing unit 34 together with the estimate data 29, the quantity data file 15, the purchase maker file 20, and the like. (Execution budget and purchase order creation step). In this case, it is also possible to create an estimate again by separately adding a certain profit rate to the formed execution budget. Further, by the input operation from the keyboard or the like as the input means 4 ′ by the operator, the formed order data 27 and execution budget data 26 are output to the printer as the printing means 13, and the purchase order, execution budget, It is also possible to print the estimate with reference to the vendor file 18.

  Thereafter, referring to the quantity data, the process calculation unit 33 calculates the work time for each material using the work time DB 17, and further refers to the procedure data file 22, the material procedure data file 23, etc. A total time data file 24 is created. The formed total time data file 24 is transmitted to the volume management server as process data via the output means 11 by the progression unit 34 together with the schedule data file 28 and the like (process management step). Note that the total time data file 24 formed by the input operation from the keyboard or the like as the input means 4 ′ by the operator is used, the procedure data file 22 or the like is referred to, and the process table is displayed by the printer as the printing means 13. It is also possible to print. It is also possible to print a supplier contact table including the above process table by referring to the manufacturer / company file 18 and the purchase manufacturer file 20.

  In the process management step shown below in FIG. 4, image data transmitted from a carpenter's mobile phone is received by the input means 4 ′, and image data is captured by an input operation from the keyboard or the like as the input means 4 ′ by the operator. After adding information on the date and schedule of the schedule, the output means 11 transmits the information to the construction progress status website. The image data is added to the image data file 25 by the operator and stored in the image data file 25, and transmitted to the progress status website as difference data of the image data file 25. On the other hand, when the volume management server detects the reception of the image data on the construction progress website, it obtains this from the construction progress website, generates an image reception confirmation notification in a predetermined format, and Send to PC. As a result, the PC of the member construction shop receives the image reception confirmation notification by the input means 4 '.

  On the other hand, as shown in FIG. 5, the volume management server receives the difference data such as the execution budget data 26 and the ordering data 27 transmitted from the PC of the member construction shop, and each construction work of the member construction shop is received. Create an appropriate ID code, store it in correspondence. Also, difference data (process data file including process data) such as the total time data file 24 transmitted from the PC of the member contractor is received, and the same ID code as described above is assigned and stored.

  Thereafter, when the image data transmitted from the member construction company is further received via the construction progress status website, the volume management server performs the volume based on the schedule based on the schedule information in the process chart of the image data file 25 ″. An arithmetic process is performed, and the generated schedule volume data 43 is stored in the storage means 8′A, and the difference data of the received total time data file 24 and quantity data file 15 is used and stored in the storage means 8 in advance. Referring to the stored material master file 14 and the like, the payment calculation and totaling process is performed according to the volume, and the generated money volume data 42 is stored in the storage unit 8′A. Data 44 is created and stored in the storage means 8 ′ A. Note that the key as the input means 4A by the operator By an input operation from over de like, dates volume data 43 is formed, and output amounts volume data 42, and the management data 44 to the printer as a printing unit 13 ', it is also possible to print.

  The management data creation unit 41 allocates the volume of the member builder, the construction cost of the carpenter, and the material price of the material maker based on the execution budget data 26 'and the ordering data 27', pays the volume, and pays the construction cost. Recorded in the management data 44 as a payment instruction for the material price. This instruction is then transmitted to the loan-related server by the output means 11′A in accordance with a command input by the operator using the keyboard or the like as the input means 4A after confirming the image data and the like. It is posted on the site and transferred as update data to the member builder's PC, the carpenter's mobile phone, and the material manufacturer's server. As shown in FIG. 5, by confirming the update status of the image data sequentially from the volume management server with respect to the PCs of the member engineering shops, it is possible to quickly evaluate the volume of the member engineering shops.

  As a result, member contractors, cooperating companies, and material manufacturers can receive high-payments without directly visiting the management headquarters, while the management headquarters do not go directly to the site for confirmation by receiving image data. You can proceed with volume evaluation and volume payment. This volume payment is also stored on the server of the management headquarters with the corresponding image data and work being clarified, so there is a possibility that it will occur with respect to payment by clearly storing the payment basis. It is possible to prevent subsequent disputes.

  FIG. 6 and FIG. 7 show an example of the flow of the member construction shop PC and the volume management server in the system for volume evaluation described above. As shown in FIG. 6, the input to the purchase maker file 20 and the schedule data file 28 to the PC of the member contractor can be facilitated by selecting a template on the menu bar. CAD data is taken in (step S1), a template is selected (step S2), an execution budget and a process table are created (step S3), and further, image data is input (step S4). The data is updated (step S5). When data is stored in the server through authentication (step S6), the result can be printed (step S7).

  Processing such as registration of image data as described above, that is, creation of the image data file 25 and transmission to the progress status website, can be performed in accordance with instructions sequentially displayed on the monitor as the display means 12.

  In addition, as shown in FIG. 7, it is useful to provide a volume totaling process using event buttons in the volume management server in order to calculate the closing date, that is, in units of months. Can be set.

  Further, in this embodiment, in order to calculate the detailed volume payment based on the closing date as described above, the member contractor's PC, as shown in FIG. 45, the external contractor payment condition data file 46, the construction cost DB 1 described above, the process database 6 (process DB), and the invoice data file 47 are included in the storage means 8.

  The main contract collection condition data file 45 stores the payment conditions from the owner to the construction company. For example, in the case of cash payment on the 5th of the month following the end of the month, the data regarding the due date of the end of the closing date and 5 days after the payment date The collection conditions are specified by data on the period. These can be specified using the ID code assigned to each schedule in the calendar function described above. The external contractor payment condition data file 46 stores the payment conditions from the construction company to the external contractor such as a carpenter or a material maker. The payment terms are specified, and the payment terms are stored in a one-to-one correspondence for each external contractor. The above-described ID code of the maker / trader file 18 is used for the association of each of the plurality of external traders.

  The construction cost DB 1 is obtained by further associating the above-mentioned execution budget data 26 with the above-mentioned contractor collection condition data file 45 and external contractor payment condition data file 46, and the estimated amount of the material manufacturer included in the execution budget unit price is Expenses of the contractor using the ID code of each material maker as the payment condition of the contractor to each material maker, and the labor cost of the carpenter as the payment condition of the contractor of each carpenter using the ID code of each carpenter Are associated with the payment terms of the owner to the construction company.

  The process DB 6 is further specified by the above-mentioned main contract collection condition data file 45 and external contractor payment condition data file 46 in the process schedule formed by distributing the schedule and work by the total time data file 24 and the schedule data file 28 described above. Specific deadline and payment date.

  The invoice data file 47 stores the contents of the invoice sent from the carpenter or the material manufacturer to the construction shop, and is sent to a keyboard or the like as the input means 4 by the operator of the construction shop who has received these bills. The amount charged is stored in association with the closing date or the payment date. Further, the billing amount is associated with the ID code described above for each material related to the billing amount so that the execution budget data 26 can be collated.

  Therefore, similarly to the quantity data file 15 described above, the volume management server receives the above collection conditions and payment conditions, materials and process schedules associated therewith, and the contents of the invoice from the PC of the construction shop through the network.

  Further, as shown in FIG. 3 (a), the server of the management headquarters that receives these data stores these data in the storage means 8′A, as well as a monthly volume totaling unit 48, a monthly payment calculating unit. (Owner payment calculation means 3), collation part 5 and anticipation evaluation part 7 are comprised in arithmetic means 9'A.

  The monthly volume totaling unit 48 counts monthly volume according to the closing date of the above-mentioned main contract collection condition data file 45 'and external contractor payment condition data file 46'. Aggregation is performed for each company, such as for the contractor's owner, carpenter's contractor, and material manufacturer's contractor, and the above-mentioned cost of the contractor and carpenter in the execution budget data 26 'of the volume are calculated. This is done by summing up the breakdown of labor costs.

  The monthly payment calculation unit 3 associates the above-mentioned volume totals for each business in the monthly volume totaling unit 48 with the due date for each business such as the above-mentioned prime contract collection condition data file 45 ′. In the case of a material manufacturer who pays in cash 60 days after the closing date, the volume of the material manufacturer in July is stored as corresponding to the payment date on the end of September, which is 60 days after the closing date. In the association with the due date, for example, when the turnovers of the construction company and the carpenter each have a turnover on the same due date, the total turnover is calculated in a state where the breakdown can be confirmed. The volume or the total volume associated with the above payment date can be displayed on the monitor of the display means 12 '.

  The collation unit 5 collates the contents of the above-mentioned invoice data file 47 ′ with the data of the execution budget evaluated for the volume from both the amount and the material, and pays by receiving the invoice from the payee. This guarantees the accounting process of Therefore, even if the execution budget is evaluated for volume, if there is no corresponding invoice data, it is carried over as accounts payable, and conversely, even if there is no volume evaluation corresponding to invoice data, it is processed as carry-over. Is done. The turnover processed amount is removed from the target of the monthly payment calculation unit 3 described above. In addition, these carry-over processes and the payment process of the following month by this can be performed by the same structure as commercially available accounting software.

  The forecast evaluation section 7 performs forecast asset evaluation of the building under construction on the closing date and the due date, refers to the process DB 6 ′ described above, accumulates the execution budget scheduled to be completed on the due date, and calculates the due date. Asset assessment based on the expected volume of Note that the above-described asset evaluation can be performed on the basis of the due date, not the due date, by an operator input from a keyboard or the like as the input means 4A. This asset evaluation can be displayed on the monitor of the display means 12 'in the same manner as the above-mentioned volume.

  Therefore, as shown in FIG. 8, the construction shop transmits the collection conditions and payment conditions in addition to the execution budget as differential data to the volume management server in advance (step S11), and received from the contractor according to the progress of the construction. The image data is transmitted to the image management server (step S13), and when a bill such as a carpenter is received, the bill data is transmitted to the volume management server (step S17). The image management server updates the construction progress status website according to the image data (step S14-1) and transfers the image data to the volume management server (step S14-2), while the volume management server executes the execution The budget or the like is saved (step S12), the progress of the construction is grasped by receiving the transfer of the image data from the image management server, and the output corresponding to this is calculated (step S15). In addition, the volume management server counts the monthly volume on the closing date (step S16), collates with the bill according to the volume (step S17), and the volume of the construction shop's volume on each payment date. Then, the carpenter's turnover amount and the material manufacturer's turnover amount are calculated (step S18).

  Based on this calculation result, the operator of the volume management server instructs the financial institution to pay from the escrow funds, so that the volume of the construction shop is paid from the owner at a time according to the payment conditions for the construction shop of the owner, In addition, the volume of carpenters and material manufacturers is paid by the owner at a time according to the payment conditions for these carpenters at the construction company. The payment instruction to the financial institution can be performed by telephone or the like, but as shown in FIG. 8, it can also be performed by mail or the like as shown in FIG. 8 (step S19). As a result of the series of processes described above, as shown in FIG. 8, the payment condition from the owner to the construction company is the payment site A, while the payment condition from the construction company to the material manufacturer is longer than the payment site A. By being site B, even if the closing date of the volume evaluation is the same, a part of it will be paid later.

  FIG. 7 shows the processing accompanying the above in the volume management server. The volume management server is configured to automatically perform daily aggregation processing at a predetermined time such as in the evening, for example, and determines whether or not daily volume aggregation processing has been completed after activation (step S21) (step S22). If it is before the predetermined time (step S23), after waiting for a predetermined time (step S24), daily aggregation processing is performed (step S25). The daily tabulation process can be configured to start at a predetermined time by, for example, interlocking with a time alarm function, and it is sufficient to determine the completion by providing an appropriate flag that is reversed upon completion.

  When the daily tabulation process is completed, it is determined whether or not it falls on a monthly accounting cutoff date by using an alarm function based on a calendar, for example (step S26). Aggregation processing is performed (step S27). Further, similarly, it is determined by the alarm function whether the invoice acceptance deadline is met (step S28). If so, the invoice is counted (step S29), and the due date is specified after collation. The completed volume is collected (step S30).

  When the image data used for the processing of the volume is received (step S31), authentication is performed using the authentication code as described above (step S32), and the image data is stored when the authentication is established (step S33-1). If authentication is not established, an error is sent by e-mail (step S33-2).

  In the above, the case where the image data is transmitted to the server of the management headquarters via the PC of the member contractor has been described. However, it is possible to save the labor of the member contractor by directly transmitting it from the cooperating contractor. Further, the above-described volume management server and image management server can be integrated into a single server, and the construction progress status website and the volume evaluation website can be constructed by a single home page operated by the server.

  Furthermore, in the above embodiment, the case where the construction contract is ordered from the member contractor to the cooperating company is shown, but the order may be ordered from the server of the management headquarters which received the construction contract data from the member contractor. In addition, the server of the management headquarters can be configured to transmit an image data acceptance mail to the member construction shop or carpenter in conjunction with the reception of the image data. In this case, for the schedule / work corresponding to the image data, the server of the management headquarters searches for a contractor or material manufacturer corresponding to the material included in the schedule / work of the next process in the schedule, and these mobile phones are searched. It can also be configured to automatically send work notifications to the telephone or server.
