2. Description of the Related Art Conventionally, the expansion and renovation of single-family homes has been performed according to the following procedure. First, the owner of the house, which is the client, makes a remodeling consultation by telephone or interview with a remodeling company, a home sales company, etc. (hereinafter referred to as a prime contractor). In the reform consultation, we heard the outline of the request from the client, and if there is a blueprint for new construction, refer to it to create a rough plan that is a rough design and a rough estimate based on this rough plan.
Give it to the client. This rough plan and rough estimate are usually provided to the client free of charge.

Next, when the requester requests a detailed design, the sales representative of the prime contractor holds a meeting with the requester on site. After that, the sales person returns to the office of the prime contractor and requests the designing person to create a detailed design drawing.
When the detailed design drawing is completed, the sales staff creates this quotation based on the detailed design drawing, and adjusts the schedule with subcontractors such as contractors, transporters, building materials contractors who are actually in charge of the construction work, Coordinate procurement of building materials. Give the detailed design drawing, this quotation, and process chart to the client.

Next, when the client places an order for the extension and renovation work, a contract is exchanged with the client. After that, the work is ordered from the subcontractor, and the subcontractor carries out the extension work. During the construction, the salesperson of the main contractor meets at the construction site during the construction and communicates information between the subcontractor and the client. When the construction is completed, the client, the sales representative of the main contractor, and the subcontractor will be present to perform a completion inspection. After the completion inspection, the sales person receives the construction completion notification signed by the client, after which the expansion and reconstruction costs are billed and settled, and the expansion and reconstruction work is completed.

However, the extension and renovation carried out by such a flow has the following problems. Like the above flow,
Rough plans and rough estimates are usually created free of charge, so it will be created only based on the materials and explanations prepared by the client. Therefore, after the rough estimate is created, it is understood that the situation at the site is different from the client's explanation at the stage of on-site meeting before the detailed design. Was sometimes low.

[0006] In addition, if the prime contractor is different from the one who built the house, or if the contractor who built the house does not manage the blueprint of the house, the blueprint of the house is prepared each time. I had to hand it over and request an extension. In addition, there are cases in which neither the contractor who built the house nor the owner of the house manages the blueprint, or the construction was not performed according to the blueprint at the time of new construction, in which case the cost of extension and renovation is high. There was also a problem that it would become.

Further, even when a rough estimate is desired at the time of requesting an extension and renovation, it is necessary to make a request by telephone or at the office of the contractor, which limits the time zone in which the request can be made, making it difficult to contact a contractor who has no business relationship. There was a problem. Further, when it is desired to obtain a matching estimate from a plurality of contractors at the time of requesting an extension and renovation, a laborious rough estimate request is made a plurality of times, resulting in even less efficient work. In addition, there is a demand for a consistent and comprehensive after-sales service after the construction of a house, and there is an increasing need for a renovation work by a housing manufacturer who undertakes new construction work and who is familiar with the house.

On the other hand, on the side of the main contractor,
Since the sales staff collectively manages from the rough estimate preparation stage to the completion of the construction, the sales staff has a heavy burden. In addition, some clients may be required to make arrangements and change designs many times, and it has been desired to develop a system that can reduce the work of the sales staff. Further, the troublesome order for the extension and renovation causes the owner of the house to hesitate to request the extension and renovation, and there is a problem that the number of orders for the extension and renovation is reduced. There is also a demand for the development of an extension and renewal quotation issuing system that enables owners of homes to easily obtain a rough estimate of the extension and renovation and find out orders for extension and renovation.

Further, since the house maker is well aware of the house built by itself, the house maker is requested to construct a system for developing a new maintenance business with the owner of the house built by the customer as a customer. Has been done. Further, when a new extension / renovation plan product is developed, it has been desired to develop a system capable of providing an appropriate extension / renovation plan to appropriate consumers in a timely manner.

As described above, according to the present invention, the client computer of the client of the extension and renovation requests the server computer of the prime contractor to request a quotation including the image of the extension and renovation request image indicating the desired contents of the extension and renovation. Since the request for quotation information is transmitted, the contractor can receive the contents of the desired extension and renovation in the form of an image. Therefore, in comparison with receiving the desired content only verbally or in writing, the client's request can be accurately grasped, and the type of building material required,
The number can be clearly understood. It is possible to smoothly hold a meeting between the extension / renovation requester and the extension / renovation manager, and prevent the client, the main contractor, and the subcontractor from recognizing the extension / reconstruction policy. . Therefore,
Estimates can be created efficiently, and the accuracy of the created estimates will be high.

Further, the building management information transmitting means is arranged to transmit the building management information together with the building identification information to the client computer, and the estimation request information receiving means is constructed to receive the estimation request information together with the identification information. Therefore, on the server computer side, it is possible to determine which building the request for quotation information received from the client computer side relates to, and it is possible to efficiently issue a quotation.

Further, since the request for the extension / renovation estimate can be sent and received with the server computer via the communication network, the client can easily and easily request the extension / renovation. Therefore, it is possible for the prime contractor to increase the number of orders for expansion and renovation. In addition, since it has a building management information database that stores the building management information of the client's building, it is possible to collectively manage the progress of the client's building since it was constructed, and when performing renovation work, etc. There is no need to collect management information about each building each time. As a result, it is possible to efficiently perform extension and renovation. Further, the prime contractor can know the tendency of each building such as strengths and weaknesses from the information accumulated in the building management information database.

Further, since the client computer transmits to the server computer the quotation request information for requesting the quotation including the image of the extension / remodeling request image indicating the desired contents of the extension / reconstruction, the original contractor in the form of text or image data. The same request for extension / renovation is shared by the requester, the original contractor, and the subcontractor sharing the quotation request information, which includes the image information of the extension / renovation request, for the quotation request. It becomes possible to do. Therefore, it is less likely that the mutual understanding will change and the extension / renovation policy will change as the meeting progresses.
