BEST MODE FOR CARRYING OUT THE INVENTION In a building system according to the present invention, quote information is submitted to an architect when the architect is selected. Therefore, the client of the building can select an architect accurately. In addition, the selection of the architect and the selection of the builder are performed independently. Therefore, the most suitable combination of the architect and the builder can be selected to satisfy the request of the construction client. In the present system, the architect and the builder are caused to present the building estimate, however, because the architect and the builder each have a different perception of the building cost. This is due to differences in the positions of architect and constructor, and also depends on individual management policies and areas of specialty. In addition, it is usually difficult for architects to completely specify the image of the building they design on the architectural plan. Therefore, when estimating the construction cost, the architect makes an estimate according to his own image as well as the building plan, while the builder simply estimates from the building plan only. Differences occur in estimates.

7).

The client terminal 3 receives the contractor estimate information and the system estimate information, and displays the information on the display by the browser (S308). On this display, it is preferable that each estimated amount is graphed so that it can be easily compared. The client, based on the displayed installer quote information and system quote information,
An installer is selected, and the selected information is transmitted to the server 1 (S309).

The server 1 receives the selection information and stores it in the building content information DB 24 by the builder selection processing unit 17 (S310). Further, the server 1 notifies the terminal 5 of the selected builder by an e-mail or the like to the terminal 5 of the selected builder based on the selection information by the builder selection processing unit 17, and The user's terminal 5 is notified by e-mail or the like that no selection has been made.

Next, a specific example of a process related to architect selection in the building system according to the present invention will be described with reference to FIG.

In this example, it is assumed that the construction cost included in the construction request information from the client is 30 million yen. The server 1 receives the building request information including the building cost information, and transmits the building request information to the architect A, the architect B, and the architect C.
Each architect A, B, C, based on the building request information,
Each of the building plans A, B, and C and an estimate of each building cost are created. In this example, the estimate of building plan A is 320
It is assumed that the estimate for the building plan B is 28 million yen, and that for the building plan C is 29 million yen.

The building plan information and the estimation information are transmitted to the server 1. The server 1 executes an estimate for each building plan. In this example,
Assume that the construction plan A costs 31 million yen, B costs 30 million yen, and C costs 28 million yen. Then, regarding the building plan A, the server 1
Along with the construction plan information, information that the architect's estimate is 32 million yen and the system estimate is 31 million yen is transmitted to the client. Similarly, for architectural plan B, the architect's estimate is 28 along with the architectural plan information.
The information to the effect that the price is 100,000 yen and the estimate of the system is 30 million yen is transmitted to the requester. In addition, with respect to the building plan C, together with the building plan information, information that the estimate of the architect is 29 million yen and the estimate of the system is 28 million yen is transmitted to the client.

The client selects a predetermined architect based on these pieces of information, and notifies the server 1 of the selection. When selecting an architect, the client can make a judgment by taking into account not only the design drawings but also the estimate of the construction cost. In particular, not only the architect's own estimate of construction costs,
The present system can also make a determination in consideration of an objectively obtained estimate, so that a more accurate determination can be made.

Next, with reference to FIG. 5, a specific example of processing relating to selection of a builder in the building system according to the present invention will be described. A case where the client selects the building plan C in the example shown in FIG. 4 will be described.

In this example, the server 1 transmits the building plan C selected by the client to the builder a, the builder b, and the builder c. Each of the builders a, b, and c creates an estimate of the building cost based on the building plan C. In this example, it is assumed that the estimate for the installer a is 29 million yen, the estimate for the installer b is 28 million yen, and the estimate for the installer c is 30 million yen.

[0086] These estimation information are transmitted to the server 1. The server 1 reads out an estimated 28 million yen on the system relating to the building plan C. And
The server 1 transmits these pieces of estimation information, that is, a system estimate of 28 million yen, a contractor a estimate of 29 million yen, a contractor b of 28 million yen, and a contractor c of 30 million yen, to the client. .

The requester selects a predetermined contractor based on the information, and notifies the server 1 of the selection. When selecting a contractor, the client can make a decision not only by simply estimating each contractor but also by taking into account the estimate objectively obtained by the present system, so that a more accurate judgment can be made. .

It should be noted that the architect information D
The information stored in B22 and the builder information DB 23 may be browsed.

Further, after the architect and the builder are selected in the present system, a settlement means capable of paying on the present system with respect to a deposit to be paid by the client, a construction cost to be paid after the completion of the construction, etc., is provided. It may be.
The payment means includes, for example, credit card payment, electronic money payment, and debit payment.

Further, in the above-described example, the example in which the builder is directed to a corporation such as a construction company has been described. However, the present invention is not limited to this.
This is because, as in the case of the architect's design, the construction work largely depends on the skill of the individual, and if the client can select the client on an individual basis, the construction that meets the request of the client can be realized. Even in light of the world of individual emphasis,
It is thought that such a concept will become mainstream.

In the above-described example, various programs installed in the hard disk and memory of the computer to configure the server can be stored in a storage medium, and transmitted via a communication medium. It is possible. Here, the storage medium includes, for example, a floppy (registered trademark) disk, hard disk, magnetic disk, magneto-optical disk, CD-ROM, DVD, R
Includes OM cartridges, RAM memory cartridges with battery backup, flash memory cartridges, nonvolatile RAM cartridges, and the like. Further, the communication medium includes a wired communication medium such as a telephone line, a wireless communication medium such as a microwave line, and the like, and also includes the Internet.
