Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a financial institution where the construction period is several months to several years, such as condominium construction and detached house construction, and the contractor is carrying out a division of labor system. The present invention relates to a collateral value calculation system and method during construction of a project suitable for use in calculating the collateral value of a house under construction. Further, the present invention is a project object having a life of several tens to several hundred years such as an apartment or a detached house, and the life of the project object varies greatly depending on maintenance and repair after delivery to the owner. The present invention relates to a system and method for calculating the collateral value of an existing project object suitable for such purposes.

[0002]

[Prior Art] From the demand of the era of real estate debt,
There is a demand in the financial market to calculate the collateral value of works such as houses under construction and liquidate them as bonds. In particular, if it is difficult for the contractor to continue the contract work during the construction of the work, if the work under construction is left as it is, the work cannot be used. The socio-economic loss is also large. On the other hand, regarding the housing under construction, the current Civil Code stipulates the lien for real estate construction (Civil Code Article 325, Article 327, Article 338) and fulfills the simultaneous fulfillment relationship between housing construction and remuneration. For civil detention (Civil Code Article 297)
And the Commercial Retention Right (Article 521 of the Commercial Code). Therefore, financial market participants need to calculate the collateral value of structures such as houses under construction within the framework of the current civil law.

Also, when it becomes difficult for the client to pay the construction fee, the construction of the workpiece must be stopped on the way. In this case, a third party may purchase the work in progress or additional financing from a financial institution
If the work in progress can be completed, the social and economic benefits will be great.

[0004]

However, there has been a problem that it is much more difficult to calculate the economic value of a workpiece in the process of construction, as compared with the case of a completed workpiece. That is, there is an economic reason that it is difficult for a contractor who takes over a work in progress to calculate the cost and period required to complete the work in progress. In addition, as a legal reason, in the construction work that is a typical example of a contract contract, the building object is a real estate under Article 86 of the Civil Code. And regarding real estate, "the establishment and transfer of property rights are not effective only due to the intention of the parties" (Article 176 of the Civil Code) If you look at it, you will not be able to compete against a third party without fail "(Civil Code No. 1
Article 77). Therefore, since the work in progress is rarely registered temporarily from the viewpoint of registration cost, it is not actually subject to transactions.

On the other hand, second-hand houses have been registered and are therefore distributed as objects of transactions. However, the building cost of a building is less likely to be reflected as an economic value, and it is common to use the number of years after construction, which is determined by the current market price ratio table, when setting the collateral value at financial institutions. Therefore, even if the maintenance is well done, only standardized value judgment based on the current market price ratio table is made, and it is rare that the resale price is properly reflected. For example, in the auction market, the actual construction cost is rarely considered in the value of a building, and the standard construction unit price is multiplied by the area of the object to calculate the reconstruction cost, and then the reconstruction cost is calculated. A uniform value is calculated by calculating the depreciation amount that is determined from the number of years after construction for the useful life.

The present invention solves the above problems. A first object of the present invention is to accurately calculate the economic value of a workpiece under construction, so that a third party can purchase the workpiece under construction. Another object of the present invention is to provide a collateral value calculation system and method suitable for a project that is used for the purpose of completing a work by using an additional loan from a financial institution. A second object of the present invention is also to provide a collateral value calculation system and method for an existing project that can appropriately reflect the fluctuation of the rebuilding price and the state of maintenance in the collateral value even after the delivery of the workpiece. To aim.

Calculate the value of the project object at the completed process step from the contract contract amount information. The completion value of the project object is calculated, for example, by the following criteria. Implementation costs (material costs, labor costs, construction equipment depreciation costs, usage fees,
Includes costs for managing the construction status). The market transaction price at which an object similar to the completed project object is traded on the market. The standard amount of tax on an object that is similar to the completed project object when taxed by the government. Changes in implementation costs such as material costs and labor costs when calculating the collateral value, and changes in implementation costs expected when executing future security interests compared to when the contract contract for the project object is concluded. Effect of interest rate based on the time difference between the time a contract is signed and the time the collateral value is calculated.

The project collateral value calculation unit 88 may calculate the collateral value for the executed process related to the project object by multiplying the contract contract amount of the executed process related to the project object by the first multiplication factor. The first multiplication factor is the already completed process, so the calculated collateral value is the contract amount compared to the calculation of the collateral value for the additional process that is necessary to complete the project object.

Next, the project price settlement server 20 receives the process inspection pass for each process of the project object notified from the project inspection management server 30 (S1202 to S1210). Then, the project price payment server 20 refers to the project payment price table 24 that records the project payment amount for each process in the project object, and refers to the project payment amount (construction price) corresponding to the process that passes the process inspection. Then, the deposit payment server 10 is instructed to pay the project payment amount from the deposited project price to the contractor 2 who has carried out the process corresponding to the process inspection pass (S1104 to S1112).

Next, the completion guarantee management server 40 manages the completion guarantee contract related to the project object for which the project price has been deposited (S1300). That is, when it becomes difficult for the contractor 2 to continue the work (continuation of construction) for the project object related to the completion guarantee contract (S
1302), the completion guarantee management server 40 receives the work of the project object from the takeover contractor registered in the takeover contractor table 44 in which the takeover contractor having the work performance (construction ability) of the project object is registered. A takeover contractor 3 that takes over (construction) is selected, and a process to be carried out (construction) is extracted by using the process inspection pass for each process (S1304). Then, the completion guarantee management server 40 sets the takeover contractor 3 who has executed (constructed) the process corresponding to the process inspection pass in the payment instruction to the deposit server 10 as the payee (S130).
6).

In accordance with the progress of these construction states, the collateral value calculation server 80 receives construction contract price information of the project object related to the completion guarantee contract (S140).
2). Next, the project inspection management server 30 notifies the project price settlement server 20 that the project inspection management server 30 sends a project to the collateral value calculation server 80 in accordance with the passing of the process inspection for each process in the project object. Notification of process inspection pass for each process on the object (S1404, S140)

FIG. 8 is a diagram for explaining the flow of the procedure for the construction contracting work using the project payment system and the project completion guarantee system of the present invention. Here, in the figure, the design supervisor 8 is the architect 7 as the client 1.
To create a design drawing of the intended building objective of 1.
At the same time, the detailed design drawing of the building object is handed over to the contractor 72 as the contractor 2. The construction object corresponds to the project object, and the takeover contractor 3 corresponds to the takeover construction company 73. The completion guarantee mechanism 5 is an organization that organically integrates the design supervisor 8, the completion guarantee management server 40, and the project price settlement server 20 to guarantee the completion of the project object to the client, and is set up by, for example, a corporation. It has a registered information processing organization.

The financial institution 60 provides a construction fund for a construction object, and includes a financial institution having a general lending function such as a bank, an investment union, and an investment company. The lending by the financial institution includes a construction financing loan for lending to the building owner 71 and a construction loan for lending to the construction company 72 as the contractor 2.
Project finance and investment of investment unions and investment companies collect investment funds by the completion of the project, the yield after completion, and the residual value, and the project funds are provided to the building owner 71 and the contractor 72 as the contractor 2. Make an investment. The non-life insurance company 62 is a non-life insurance company, and bears risk hedging against accidental accidents that accompany the construction of the building object.

The member maker 64 supplies the construction company 72 with interior materials, exterior materials, building materials and the like used for construction of the construction object. The subcontractor 66 carries out the construction of the construction object according to the instructions of the construction company 72. Temporary construction, foundation construction, roof construction, outer wall construction, interior construction, joinery construction, sheet metal construction, plastering construction, tile construction, painting. Applicable to specialists in each work such as construction, electrical work, water supply and drainage work, gas piping work, equipment and equipment work, beauty work, and outer trench work. The member maker 64 and the subcontractor 66 are treated as the contractor 2 in relation to the project price settlement server 20.

Next, the procedure of the construction contracting work will be described with reference to FIG. First, the building owner 71 and the design supervisor 8 hold a detailed meeting on the building object (step). When the details of the building object are agreed between the building owner 71 and the design supervisor 8, the design supervisor 8 hands over the detailed design drawing to the builder 72 (step). On the other hand, the construction contractor 72 provides the design supervisor with the quotation details (step).

Next, the completion guarantee mechanism 5 receives the ownership of the construction object from the builder 72 in order to use the project price settlement system (step A). Note that, instead of the physical property structure in which the ownership of the building object is transferred, a receivable structure in which a claim is transferred with respect to the receipt of the construction contract price of the building object may be adopted. In addition, the completion assurance mechanism 5
When the builder 71 tries to cancel the construction contract contract for the construction object on the way, for the construction contract price corresponding to the process in which the construction of the construction object has already proceeded, priority is given to the payment from the project price. Conclude the special contract to receive (step B). In addition, instead of concluding a preferential repayment contract for the cancellation of the construction contract contract during construction, the builder 71
It may be configured to receive the transfer of the lien of the building object from the company. Further, the completion guarantee mechanism 5 guarantees the payment to the member maker 64 and the subcontractor 66 by using the project price settlement system (step C), and passes the completion guarantee to the builder 71 (step D). The architect 71
Or, if there is an agreement from the financial institution 60, the component manufacturer 64
Similarly to the subcontractor 66 or the subcontractor 66, the construction contractor 72 may be directly provided with a payment guarantee or payment.

The financial institution 60 provides the construction contractor for the construction object to the building owner 71 as an investment and loan of the project fund (step A), or makes a loan to the contractor 2 as an investment and loan of the project fund. (Step B). Investment and loan of the deposited project funds are managed by the project price settlement server 20. Further, in order to prevent the project completion guarantee system from being affected by an unforeseen disaster, an insurance contract regarding the construction of the construction object is concluded with the non-life insurance company 62 (step C). The insurance contract allows the construction company 72 to carry out risk hedging against construction damage insurance, occupational accidents, PL (Product Liability Law), fire, etc. (step D).

The builder 71 deposits the construction contract price of the construction object and transfers the payment authority to the project price settlement server 20 (step). The actual deposit management is performed by the deposit server 10. The construction company 72 executes the construction of the construction object at the construction site (step). Then, the construction company 72 voluntarily inspects the construction state of the construction object at a level as scheduled by the Product Assurance Act, if necessary (step). Then, the construction company 72 reports the result of the self-inspection to the completion assurance mechanism 5 (step).
This report is made for each process without delay each time a predetermined process is completed for the building object.

When the construction state of the building object progresses and the construction of the process requiring the construction state inspection by the design supervisor 8 is completed, the design supervisor 8 goes to the construction site without delay and constructs the construction object. Inspect the condition (step 10). Then, the design supervisor 8
The project inspection management mechanism 9 is notified for each process to be inspected (step 11).

In the project inspection management mechanism 9, the project inspection management server 30 records the construction state inspection result of the building objective by the design supervisor 8. Further, when the construction supervision of the project inspection management organization 9 completes the construction of the process requiring the construction state inspection, the construction supervision person conducts the construction state inspection of the construction object without delay (step 12). If the inspection result of the corresponding process is passed, the project inspection management mechanism 9 (project inspection management server 30) to the project payment server 2
A payment instruction is issued to 0 (step 13).

Next, with reference to FIG. 4, the project price settlement system will be described by taking the case of complying with the contract construction price payment regulation of FIG. 9B as an example. The project price settlement server 20 receives the deposit state of the construction contract price of the building object from the deposit server 10 that manages the deposit state of the construction contract price of the building object (S1102). Then, when the project inspection management server 30 notifies that the foundation construction completion inspection has passed (S1202), the project price settlement server 20 did the contractor 2 for the foundation construction price, the member manufacturer 64 who supplied the material, and the actual construction. Subcontractor 6
Direct deposit server 10 to pay 6 (S
1104).

When the project inspection management server 30 notifies that the roof construction completion inspection has been passed (S1204), the project price settlement server 20 performs the roof construction fee on the contractor 2, the member manufacturer 64 who has supplied the material, and the actual construction. Deposit server 10 to pay subcontractor 66
(S1106). When the project inspection management server 30 notifies the completion of the interior groundwork completion inspection (S1206), the project price settlement server 20 contracts the interior groundwork price to the contractor 2, the material manufacturer 64 who supplied the material, and the subcontractor who actually performed the construction. The deposit server 10 is instructed to pay to the trader 66 (S1108).

When the project inspection management server 30 notifies the construction completion inspection pass (S1208), the project payment server 20 instructs the deposit server 10 to pay the construction completion payment to the contractor 2 (S).
1110). Finally, the project inspection management server 3
When the follow-up inspection pass is notified from 0 (S120
8), the project price settlement server 20 instructs the deposit server 10 to collectively pay the reserved amount to the contractor 2, the material manufacturer 64 that has supplied the material, and the subcontractor 66 that has actually performed the construction (S1112). .

Next, in addition to the project price settlement system, the contractor of the project completion guarantee system is provided with a contract.
The case where 1 is concluded will be described. By concluding a completion guarantee contract for the construction of the construction object using the special contract of the project completion guarantee system and pre-selecting the succeeding construction company 73, the builder 71 has the following effects. Since the completion guarantee contract guarantees the performance of the contract work contract, the completion, quality and specifications of the building object are guaranteed, and the builder 71 can request the builder to construct the building object with peace of mind. Even if the contractor 72 encounters a situation in which it is difficult to carry out the contract work, the successor contractor 73 guarantees the fulfillment of the contract work contract, so that the construction object is surely completed.

The selection criterion for the takeover construction company 73 is that the location of the construction site and the location of the takeover construction company 73 are in the same area, or that the construction scale of the construction object is compared with the work performance of the takeover construction company 73. Whether or not it is appropriate, whether the construction unit price of the takeover construction company 73 is appropriate in comparison with the market price, etc. is comprehensively judged.

In FIG. 8, the broken line portion illustrates the procedure flow of the project completion assurance system.
In the completion guarantee management server 40, the takeover contractor 73 having the ability to take over the construction of the building object is selected from among the takeover contractors 73 as the takeover contractor 3 registered in the takeover contractor table 44 ( I). When it becomes difficult for the contractor 72 as the contractor 2 to continue the operation of the construction object related to the completion guarantee contract, the successor 73, extracted by the completion guarantee management server 40, is requested to the builder. The remaining work is ordered by 71 (b). The takeover construction company 73 carries out the remaining work in the construction of the construction object at the construction site (C). Then, the completion guarantee management server 40, in the payment instruction to the deposit server 10 by the project price settlement server 20, on condition that the process inspection pass for the remaining work is passed, the execution price of the remaining work is taken over by the contractor 73 and the member manufacturer who supplied the material. 64, subcontractor 66 who did the actual construction
Pay to (d).

In FIG. 8, the chain double-dashed line portion illustrates the procedure flow in the cooperation between the project completion guarantee system and the project collateral value calculation system. The collateral value calculation server 80 stores the detailed design drawing handed over by the design supervisor 8 to the builder, and the bibliographic items of the detailed design drawing are stored in the design book management table 81 (e). In addition, the collateral value calculation server 80 records a record of the process inspection pass for each process in the project object carried out by the project inspection management mechanism 9 and the construction company 72 in the project progress management table 82.
Save to (F). Furthermore, the collateral value calculation server 80
Is a contractor for the construction price and the material price instructed by the project price settlement server 20 to the deposit server 10.
The payment instruction to the component manufacturer and the subcontractor is stored in the project fulfillment history table 83 (g).

Next, the project completion guarantee system will be described using the example of FIG. The initial contractor 2 constructed the construction object up to the stage where the foundation construction completion inspection passed and the roof construction completion inspection passed, and then it became difficult to continue the construction (S1302). Then, the completion guarantee management server 40 selects the takeover contractor 3 (S
1304). The takeover contractor 3 is
The construction was carried out until the completion of the interior groundwork completion inspection and the completion inspection pass judgment, and the construction object was delivered to the building owner 71. Therefore, the completion guarantee management server 40, the project price settlement server 20, and the deposit server 10 are linked to each other, and the takeover contractor 3,
The interior foundation work price and the construction completion price are paid to the member manufacturer 64 that has supplied the material and the subcontractor 66 that has actually performed the construction.

FIG. 9 is a diagram showing an example of the deposit deposit regulation and the deposit payment regulation in the project payment settlement system of the present invention. There is. The price deposit rules are a fixed amount per building object (for example, 200,000 yen) as a preliminary inspection fee, contract contract, contract start, construction start, roof completion, interior groundwork completion, completion inspection pass The builder 71 should deposit 1/5.

The payment rules are as follows: basic construction completion inspection passed, roof construction completion inspection passed, interior groundwork completion inspection passed, construction completion inspection passed, foundation construction, roof construction,
9 for the work price of each process of interior groundwork and construction completion
0% is the construction company 72, 64 is the material manufacturer that supplied the materials,
Pay the subcontractor 66 who did the actual construction. Then, after passing the building object to the building owner 71, a follow-up inspection is performed after a certain period of time, and if the follow-up inspection is passed, a reservation for the construction fee of each process is paid. The follow-up inspection is, for example, an after-maintenance inspection performed after 3 months. Retainage is about 10% of the basic construction, roof construction, interior groundwork, and construction completion.

Next, a description will be given of a collateral value calculation system suitable for an existing project object that is used after the construction object is completed. After the construction object is completed, it is customary that the building is registered for preservation, so even when calculating the collateral value by a financial institution, for example, as a replacement cost, the annual depreciation is added to the standard building cost of the Housing Finance Corporation. After deducting, a certain multiplication factor (for example, 60% if the usage is for personal use,
The collateral value is calculated at 40% for rent.

However, apart from the case where a building is demolished and a new house is constructed, if the maintenance of the building is good and the market sale price of the building is not appropriate, the homeowner will Don't try to repair. In the system and method for calculating the collateral value of an existing project object, which is the second invention, by accurately recording the design document, construction status, and maintenance status of the project object, it is possible to accurately estimate the replacement price. It is also possible to accurately calculate the current value rate.

FIG. 22 is a configuration block diagram of a collateral value calculation system for an existing project, showing an embodiment of the present invention. In the figure, a replacement price calculation unit 91 calculates a replacement price at the time of calculating the collateral value of an existing project, and includes a design book management table 81, a project progress management table 82, a material market data unit 92,
It is connected to the construction integration data section 93. The repurchase price calculation unit 91 refers to the design document management table 81 and the project progress management table 82 to grasp the details of the required materials and the required man-hours when the existing project is reconstructed by the same construction method as at the time of construction. The re-procurement price calculation unit 91 calculates the re-procurement price of the existing project by referring to the material market condition data unit 92 and the construction integration data unit 93, and accumulating the materials, the man-hours, and the unit cost per man-hour when the collateral value is calculated. To do. In this case, when there is little change in the material price and construction price of the existing project at the time of calculating the collateral value and at the time of construction, the repurchase price calculation unit 91 further determines whether the debt fulfillment status recorded in the project fulfillment history table 83 The information is taken into account in the replacement price calculation.

The present valuable value calculation unit 94 calculates the present value of the existing project, and calculates the replacement price calculated by the replacement price calculation unit 91 based on the useful life and elapsed years of the existing project. Multiplied by the current value ratio
Furthermore, the repair status recorded in the maintenance record database 84 is considered. The collateral value calculation unit 95 refers to the secondary market data 96 of the project object, the average period required for cash conversion, the purchaser when the collateral property is temporarily sold,
Also, taking into account the status of the seller of the project object,
Calculate the collateral value rate. In a market environment where cash exchange is easy, the value is close to the current value price calculated by the current value calculation unit 94, and in a market environment where cash conversion is difficult, it is a multiplication factor for the current value calculated by the current value calculation unit 94. Lower the rate.

Next, the usage state of the collateral value calculation system of the existing project thus constructed will be described. FIG. 23 is a diagram showing an example of calculation of the collateral value for a building when the existing project is a wooden house. Here, in order to simplify the explanation, there is no change in the material price and construction price of the existing project at the time of calculating the collateral value and at the time of construction, and the replacement price calculation unit 91 simply uses the initial construction price as the replacement price. A case will be described. In addition, the current valuable value calculation unit 94 sets the useful life of the wooden house to 30 years, and depreciates it by a fixed amount every 3% based on the building price. After 30 years, depreciation is set to zero and the building price is 10%. Is regarded as the residual value of the building. In addition, if there is an inspection or repair, the repair work price will be depreciated by a fixed amount every year before the next repair work. Regarding the utility of repairs on wooden houses, the present value is calculated as the remaining life extended with respect to the number of years elapsed after the construction of the wooden house is equal to the repair work price, but the remaining life extension by repair work is extended. When the effect is large, the present value may be calculated by multiplying the repair work price by a certain multiplication factor.

In the example shown in FIG. 23, the initial construction price of the existing project is 15 million yen, and the remaining value of the building after 30 years is 1.5 million yen after depreciation by 450,000 yen every year. Becomes For inspection and repair, in accordance with the above-mentioned inspection and repair record sheet for my home, 1 year after delivery, 3
It shall take place 5 years later, and after 5 years, it shall continue at 5 year intervals until the building is demolished or decays. In the case of a wooden house, decay means a state in which the roof falls and the walls collapse. About 40 years after construction if proper maintenance is not performed, and 70 years or more after construction if properly maintained. Leads to decay.

In the example shown in FIG. 23, the repair work does not occur in the one-year inspection, the repair work cost 200,000 yen occurs in the three-year inspection, and the repair work cost 500,000 yen occurs in the five-year inspection. After the 10-year inspection, 1.5 million yen was incurred for repair work every 5 years. At this time, the repaired building value becomes the current value of the existing project calculated by the current value calculation unit 94. In addition, the repair work price for repairs performed at intervals of 5 years is 1.5%, which is 10% of the building price,
It shall be amortized over 5 years. By carrying out regular repairs, the residual value of the wooden house can be kept relatively high, and it can be prevented from decaying.

In the above embodiment, the case where the present valuable value is calculated based on the replacement price as the collateral value calculation system for the existing project and the repair work price is also taken into consideration is explained. It is not limited, but regarding buildings among the project objects,
It is suitable for use in financial institutions when considering the repair work price against various collateral evaluation criteria. For example, at a financial institution, various collateral evaluation criteria are the fixed sale amount, the minimum sale amount based on the auction procedure in the court,
There are appraisal values by real estate appraisers, transaction case comparison method, profit reduction method, output value by cost method, and property tax assessment, but in general the remaining life of a building is extended depending on repair work. Therefore, it is advisable to reflect the considerable period of extended remaining life in the calculation of the current value.

Further, according to the collateral value calculation system for an existing project of the present invention, a replacement price calculation unit for calculating a replacement price when the existing project is reconstructed by the same construction method as the construction, and the replacement price. The replacement price calculated by the calculation unit is multiplied by the current value ratio calculated based on the useful life and elapsed years of the existing project, and the remaining life extended for the elapsed years due to repairs to the existing project is considered. Then, a current value calculation unit that calculates the value that the existing project currently has, and a collateral value calculation unit that calculates the collateral value ratio for the existing project by taking into consideration the secondary market state of the existing project. I have it. Therefore, fluctuations in construction costs that occur after the delivery of the project object is factored into the collateral value at the replacement price calculation section, and the maintenance status of the project object is factored into the collateral value at the current value calculation section to ensure proper maintenance management. It becomes possible to properly evaluate the project object that has been made in the market, and it is possible to accurately calculate the collateral value of the project object whose years have passed since its completion.
