  The estimation work of a building has many items (building materials) and is a difficult work, and the creation of an execution budget requires a considerable amount of man-hours. Estimates by builders themselves are often only rough estimates, such as making estimates according to option construction based on the unit price or standard unit price. In addition, when requesting an estimate operation to each store of various member items, there are various aspects of the integration processing for the same member item depending on the store, and there is a lack of objectivity.

  On the other hand, in the past, there has been no system in which a manufacturer intervenes as a contractor in addition to a builder as an estimate requester and each dealer who performs an estimate when estimating a building. This is due to the following reason.

  For example, it is assumed that a manufacturer sells two types of building materials to four dealers, and each dealer ships to two builders with two types of specifications (that is, four types of products) for each building material. In this case, each dealer may have 16 types of data of 2 types of building materials × 4 builders × 2 types of specifications, but the manufacturer needs to have 64 types of data. In other words, it is necessary to have an enormous amount of data as it goes upstream in the commercial flow (commercial transaction flow, that is, the flow of money), and there is a risk that a system failure may occur. Therefore, it has been difficult to construct an effective estimation system in the construction industry where the number of building materials handled and the number of hierarchies in commercial distribution are large.

  An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a building total estimation system that makes it possible to estimate a building that is effective even in an industry with a large number of handling members and commercial distributions.

(4) The estimate requester terminal creates an execution budget based on the received estimate data and creates an estimate for the client.
(5) In response to a request from the owner, for example, the estimate requester terminal changes and inputs product selection information (for example, information related to the design of building materials) in the estimation conditions, and sends the changed product selection information to each dealer terminal. Then, each store terminal updates the estimate data based on the changed product selection information.

The integration data is information such as integration items, area, length, and quantity, for example.

  The structure information is data that is input by the designer from the outside of the structure CAD 211 and corrects the architectural drawing data. For example, architectural drawing data may be structurally insufficient because it is design-based. In this case, for example, structural information such as adding a column to the wall surface is added, and the architectural drawing data is corrected. As final architectural drawing data is obtained in this way, the integrated data is created by extracting the integrated items such as the presence of sliding doors, the area of the sliding doors, the length of the sliding doors, the quantity of the sliding doors, etc. To do.

  In addition, you may make it add the structure information to architectural drawing data as needed. That is, for example, in the case of the aforementioned sliding doors, it is necessary to add structural information to the architectural drawing data. However, in the case of “flooring”, the structural information is added to the architectural drawing data due to the structure of the member. It is unnecessary. Therefore, actually, the structure CAD 211 adds structure information to the architectural drawing data as necessary.

FIG. 10 is a diagram illustrating a processing flow when the product selection information is changed and input in response to a request from the owner 10. The flow of processing will be described below according to step numbers S41 and S42 in the figure.
(S41) The property data / estimation condition input transmission unit 11 of the estimate requester terminal 1 changes and inputs the product selection information.
(S42) The property data / estimation condition input transmission unit 11 transmits the changed product selection information to the dealer terminal in charge of estimating the building material related to the product selection information via the network 6. For example, when the color information of the interior material as an example of the product selection information is changed, the color information of the interior material is transmitted to the store terminal in charge of estimating the interior material. Each dealer terminal updates the estimate data based on the changed product selection information.

  According to the processing shown in FIG. 10, the estimated data can be flexibly changed according to the request of the owner 10 while respecting the uniqueness of each dealer terminal in terms of price.

  Here, an embodiment of the present invention will be described by taking an “opening” as an example of a building material to be estimated.

  The estimate requester terminal 1 inputs the property information and the estimation conditions selected by the owner 10 by the property management system 110 (S1 in FIG. 6). Here, in the estimation condition, an estimation object “opening # 1”, a commercial flow, and a product selection “sliding door” are input. The product code A1 is determined by the product selection “sliding door”, and “A store (with A terminal)” is determined by this and the commercial flow.

  After this, the requester terminal 1 uses the architectural design CAD 111 according to the property information selected by the owner 10 and the estimation conditions ("opening # 1" is "sliding door") and the design hopes and opinions of the owner 10. CAD data is created (“sliding door” is adopted for “opening # 1”), and based on this (in parallel), architectural drawing data is created (S2 in FIG. 6). As a result, the area, length (thickness or width), and number of the “sliding door” that is the estimation target “opening # 1” are determined on a design basis (to the extent that they can be structurally changed).

  Therefore, the estimate requester terminal 1 transmits the created architectural drawing data to the integrated trustee terminal 2 via the network 6 by the transmission unit 112 (S3 in FIG. 6). At this time, as indicated by a dotted line in FIG. 1, the property information and the estimation conditions are also transmitted to the total trustee terminal 2.

  Thus, since the requester terminal 1 does not need to include the product master 311 and the customer master 312, the storage capacity can be reduced and the labor of data input can be saved. Further, since the requester terminal 1 does not need to include the request destination determination unit 220 for requesting a quote and does not need to include the structure CAD 211 for accurate estimation, the processing load of the computer can be reduced. Can do.

  The total trustee terminal 2 receives the above-mentioned data from the estimate requester terminal 1 by the property data / estimation condition receiving unit 210 (S11 in FIG. 7), and adds structure information to the architectural drawing data therein by the structure CAD 211. Integration data is created (S12 in FIG. 7). Unlike the wall surface, the estimation target “opening # 1” may cause a lack of strength due to the opening, and may be changed as a result of the structural design. Accordingly, the area, length (thickness or width), and number of “sliding doors” may be changed, and as a result, the type (product code) of “sliding doors” may be changed. Accordingly, the integrated data, that is, the area, length (thickness or width), and number of the “sliding door” that is the estimation target “opening # 1” are accurately determined on the design base and the structure base.

  In the past, not only “sliding doors” but also “windows” and “cross (wallpaper)” etc., because the estimation results fluctuate in units of several centimeters. It was not possible and it was accepted. Furthermore, since the architectural drawing data is changed a plurality of times in most cases after repeated meetings with the client 10, even if the architectural drawing data is obtained, it is sufficient to predict the approximate value.

  In the trustee terminal 2, the request destination determination unit 220 uses the request destination table 222 to determine a store terminal (for example, the store terminal 3) in charge of the estimate of “opening # 1” (FIG. 7). S13), the estimated basic information related to the “opening” is transmitted to the determined store terminal 3 (S14 in FIG. 7). Here, as described above, the product code A1 is determined by the product selection “sliding door”, and “A store (with A terminal)” is determined by this and the commercial flow. Based on these, the request destination table 222 is determined. Can know the IP address of the store terminal 3 (terminal A). At the time of this transmission, as indicated by the dotted line in FIG. 1, in addition to the integrated data, the property information, the estimation conditions, and the architectural drawing data are transmitted. This is basic estimation information. Further, for the estimation target “opening # 2”, for example, estimate basic information is transmitted to the store terminal 4.

  As described above, the integration trustee terminal 2 does not need to include the product master 311 and the customer master 312 even though the integration is entrusted, can reduce the storage capacity, and can save the trouble of data input. Instead of this, it is possible to request the store terminals 3 to 5 for integration only by providing the request destination determination unit 220 for requesting an estimate. Further, the integration trustee terminal 2 only includes the structure CAD 211 for accurate estimation, and can request the store terminals 3 to 5 for integration using accurate integration data. Furthermore, since the integration trustee terminal 2 receives the property information, the estimation conditions, and the architectural drawing data from the estimate requester terminal 1 for each estimation, it is not necessary to create or prepare them.

  The store terminal (for example, the store terminal 3) receives the estimated basic information relating to the “opening # 1” from the integration trustee terminal 2 by the estimated basic information receiving unit 310 (S21 in FIG. 8), The sending unit 313 creates estimate data using the product master 311 and the customer master 312 and sends it to the quote requester terminal 1 (S22 in FIG. 8). Here, the property code and property name of the estimate data are created based on the property information. The product code is created based on the estimate condition, and the product name is created by referring to the product master 311 using the estimate condition. The estimated quantity is created based on the accumulated data. The estimated unit price is created by referring to the product master 311 using the estimated condition. The estimated amount is calculated using the estimated quantity and the estimated unit price. The transmission address of the quote requester terminal 1 can be known as a fax number (or e-mail address) included therein by referring to the customer master 312 using, for example, a customer code included in the property information.

  The estimate requester terminal 1 receives the estimate data for the estimate target “opening # 1” from the dealer terminal 3 by the estimate totaling unit 120 (S31 in FIG. 9), and uses the product master 122 by the table creation unit 121. Various documents (and electronic data) such as an execution budget and an estimate for the client 10 are created by summing up by construction (construction category (or property name)) (S32 in FIG. 9). At this time, since the property data and property name are included in the estimate data, the property can be specified and aggregated.

  In this way, the dealer terminals 3 to 5 only have to accumulate only the members of the category assigned to themselves in advance, and therefore only have the product master 311 and the customer master 312 necessary for that purpose, and the storage capacity is reduced. It can be reduced and the labor of data input can be saved. Further, since the dealer terminals 3 to 5 receive the property information, the estimation conditions, and the architectural drawing data from the integration trustee terminal 2 every time it is estimated, there is no need to create or prepare them.

  Next, for example, when the requester terminal 1 receives a request from the owner 10 to change the color of “sliding door”, it changes the color information of “sliding door” (S41 in FIG. 10). The color information of “sliding door” is transmitted to the store terminal 3 as the product selection information without going through the integration trustee terminal 2 (S42 in FIG. 10). The dealer terminal 3 updates the estimated data based on the color information of the “sliding door” after the change. At this time, in order to use the previous estimate data, for example, the estimate data is transmitted from the estimate requester terminal 1. Alternatively, the store terminal 3 may store the estimated data.

  The estimate requester terminal 1 receives the updated estimate data from the dealer terminal 3 (S31 in FIG. 9), and again creates an execution budget and an estimate for the client 10 (S32 in FIG. 9). This makes it possible to easily estimate more accurately according to the progress of the meeting with the owner 10 (according to the depth of construction) using the previous estimate data without going through the total commissioner terminal 2 Can be changed. In addition, you may repeat the process of FIGS. 6-9 suitably about the same property.

Further, as will be described below, in another embodiment of the present invention, for example, the integration trustee terminal 2 adopts a configuration that performs estimation in addition to integration. In addition, the estimate requester terminal 1 adopts a configuration that not only simply aggregates the estimate data transmitted from each dealer terminal, but also estimates the building material itself and creates an execution budget using the estimate result.
(1) Integration / Estimation by Integration Contractor Terminal 2 The integration contractor terminal 2 receives architectural drawing data from the estimate requester terminal 1, and performs basic numerical values, member integration, and estimation. The integration / estimation data and the estimate prepared by the integration trustee terminal 2 are returned to the estimate requester terminal 1.

  In accumulating, for example, exchange sheets for accumulating support for “roof / outer wall / foundation”, “structural material”, “interior fitting, interior building material” are exchanged.

  The integration support meeting sheet is provided with an entry column for the commercial flow and an entry column for the estimate requester terminal 1 that is the request source for the integration / estimation. The accumulation support meeting sheet is provided with a classification column for each item, whether only quantity accumulation or estimation is performed. The integration / estimation result is created as an integration data file including the estimation data.

In this embodiment, the integrated data includes, for example, the following items. It should be noted that “builder” described in the data item in each data (accumulation data, estimate, purchase order, etc.) described below indicates the estimate requester terminal 1.
(Find items) Estimate No. , Estimate date, dealer terminal name, builder name, property name, remarks, house specification name (detail item) , Construction name, product number, product name, description, quantity, unit name, design price (list price), design price, retailer rate, estimated unit price, estimated price, supplier name The item "site name" in the accumulated data is For example, a housing estate name or the like is set, and a residence name or the like is set in the item “property name”, for example.
(2) Estimate at each dealer terminal Each dealer terminal receives the cumulative data and the estimate from the cumulative commissioner terminal 2. Each dealer terminal estimates the building materials handled independently by each dealer terminal in accordance with the housing specifications of the requester terminal 1 and creates an estimate together with the estimation result performed by the total commissioner terminal 2 And transmitted to the estimate requester terminal 1.

  If there is a request from the estimate requester terminal 1 for building materials not handled by each dealer terminal, only integration data is transmitted to the estimate requester terminal 1.

  Of the building materials handled at each dealer terminal, for the building material estimated at the total trustee terminal 2, the amount is calculated using the unit price for the estimate requester terminal 1.

  For other estimated products, the product number, product name, description, construction name, etc. are converted according to the housing specifications of the requester terminal 1 based on the integration data, and the quantity is converted according to the integration rules of the requester terminal 1 (Conversion rate and reserve number can be taken into account). Then, the amount of money is calculated using the unit price for the requester terminal 1 to create estimated data and a written estimate.

  The unit price for the requesting client terminal 1 is set to purchase price × (1 + profit rate), calculated from a fixed price, or input.

In this embodiment, for example, the following items are described in the estimate.
(Find items) Estimate No. , Estimated date, estimated expiration date, builder name (= customer), property name, remarks, estimated total price, housing specification name, dealer terminal name (detail item) , Estimate date, builder name, property name, construction name, product number, product name, description, quantity, unit, unit price, amount, remarks (part)
(3) Estimate calculation by estimate requester terminal 1 The estimate requester terminal 1 receives the estimate data from each dealer terminal and creates an execution budget book for the house according to the house specifications.

  The estimate data transmitted from each dealer terminal is utilized as it is for creating an execution budget. For building materials other than the building material for which the dealer terminal has made an estimate, an estimate is made based on the integrated data provided from the dealer terminal, and an execution budget document is created based on the estimation result.

  At this time, using the product name table and product number conversion table, which will be described later, the product number and product name are converted according to the housing specifications, the quantity is converted, the construction name is converted, and the supplier is converted. To calculate the amount.

  The estimate requester terminal 1 creates an estimate for the client 10 from the execution budget data. In the creation of an estimate for the client 10, the work name may be rearranged to be easily understood by the client 10.

  The unit price for the owner 10 is set to purchase price × (1 + profit rate), calculated from a fixed price, or input.

  The estimate requester terminal 1 issues a purchase order from the execution budget data. The purchase order is arranged for each supplier and ordering time division, and is replaced.

For example, the following items are described in the estimate for the client 10.
(Find items) Estimate No. , Estimated date, Estimated expiration date, Property name, Remarks, Estimated total amount, Housing specification name, Builder logo, Builder name (Mid-term item) , Estimated date, Site name, Property name, Remarks, Construction name, Construction type total amount (Detail item) , Estimate Date, Owner Name, Site Name, Property Name, Construction Name, Item Name, Product Number, Product Name, Description, Quantity, Unit, Unit Price, Amount For example, the following items are described in the purchase order.
(Find items) Order No. , Order date, desired delivery date, supplier name, property name, remarks, builder logo, builder name (detail item) Item name, product number, product name, description, quantity, unit, unit price, amount (total items) In the embodiment of the present invention, among the found items of the integration data, 11 is an estimate by the integration trustee terminal 2, an estimate by each dealer terminal, an execution budget and an order form created by the estimate requester terminal 1.
