The Obtain Location Information button 181j is assigned a function of obtaining location information of the ordering terminal 3 using a current location obtaining function or the like, and automatically reflecting an address based on the obtained location information in the delivery location input section 181f.

[0069] Each of the contractor input section 181a, the purchaser name input section 181b, the person in charge information input section 181c, the site name input section 181d, the delivery date and time input section 181e, and the delivery location input section 181f has a text box, allowing the purchaser to input any characters.

[0070] When the Confirm button 183 is selected, a Send button 185 to which a function of sending the order data is assigned is displayed. When the Send button 185 is selected, the order data is sent to the management server 2 and the order-receiving terminal 4 of the specified contractor. In other words, it is possible to order construction materials from outside based on the calculation result (required quantity) calculated based on the specifications and construction quantity.

[0071] As described above, the client can order building materials. As described above, in the present invention, the required quantity is automatically calculated based on the specifications and construction quantity entered on the quantity input screen 100, and an image image corresponding to the required quantity is displayed. Here, in the present invention, the client can return from the screen where the image image is displayed (the calculation result screen 130 shown in FIG. 5 in this embodiment) to the screen where the specifications and construction quantity are entered (the quantity input screen 100 shown in FIG. 2 in this embodiment) to change the specifications or construction quantity (required quantity).

[0072] If the specifications or construction quantity (required quantity) are changed, the required quantity is recalculated and the content of the image changes according to the change in the required quantity. Figure 11 shows the calculation result screen 130 before the required quantity calculated based on certain specifications and construction quantities is changed, and Figure 12 shows the calculation result screen 130 when some building materials (Ortac jaw tape) are deleted from the example of Figure 11.

[0073] For the sake of convenience, in the following description, in Figs. 11 and 12, the part of the image that changes in response to a change in the required quantity is referred to as an image change section 135. In the example shown in Fig. 11, the required quantity includes "Ortac chin tape: 10.5 rolls". Based on this, an image including an image 135a of Ortac chin tape is displayed in the specification image display section 132. On the other hand, in the example shown in Fig. 12, "Ortac chin tape: 10.5 rolls" is deleted from the required quantity. Accordingly, in place of the image 135a of Ortac chin tape, an image including an image 135b of a state in which Ortac chin tape is not present is displayed in the specification image display section 132. In other words, the presence or absence of a certain building material can be visually recognized. Although not shown, when the total amount of a certain building material changes, the content of the image changes in response to the amount of change.

[0074] With the above configuration and operation, when the required quantity is changed, the content of the image changes in accordance with the change in the required quantity, so that the client can visually confirm whether the required quantity is appropriate, i.e., whether the order content is appropriate, while imagining the state of construction, thereby improving convenience for the client when ordering building materials.

[0075] The document data management system of the present invention corresponds to the material order support system 1 of the above embodiment, the specification setting section corresponds to the specification setting section 101, the construction quantity input section corresponds to the quantity input section 102, the material calculation section corresponds to the calculation result display button 104, the calculation result display section corresponds to the calculation result screen 130, the required quantity display section 131, and the specification image display section 132, the ordering section corresponds to the send button 185, and the inventory storage section corresponds to the auxiliary storage section 36 or the auxiliary storage section 23, but this invention is not limited to this embodiment and can be in various other embodiments. Also, the screens and specific configurations given in the above embodiment are merely examples and can be appropriately changed according to the actual product.

[0076] In the above embodiment, the case where construction materials for waterproofing work are ordered, that is, the construction materials ordered are waterproofing materials, has been described as an example, but the present invention can also be used when ordering painting materials and sealing materials. In both cases of ordering waterproofing materials and sealing materials, the specifications are set on the quantity input screen, and the required quantity is calculated by inputting the construction quantity, and an image is also displayed on the calculation result screen based on the required quantity. Therefore, the same effects as those of the above embodiment can be obtained even when ordering waterproofing materials and sealing materials.

[0077] In addition, the total quantity for each item name included in the order data may be subtracted according to the inventory quantity (inventory quantity) by referring to the inventory data of the building material at the client, if the inventory of the corresponding item name exists. In this way, the client can consume the inventory of building materials while ordering an appropriate amount of the building materials that are insufficient. In other words, the convenience of the client when ordering building materials can be improved. Furthermore, when the construction (specification) is specified, the type and quantity of building materials required for the construction (specification) are displayed, so that even a new employee or other person who is not familiar with the construction can understand the type and quantity of the building materials required, and can check whether the building materials are in stock and subtract the building materials that are in stock to create appropriate order data. In addition, an operation button (automatic subtraction switching means) for switching whether or not to apply automatic subtraction according to the inventory quantity may be provided on the quantity adjustment screen 170. In this way, building materials can be flexibly ordered according to the individual circumstances of the client, and the convenience of the client when ordering building materials can be further improved. The data on the inventory of building materials at the client may be stored in the management server 2. [Industrial Applicability]
