Next, the operation of this embodiment configured as described above will be explained with reference to the flowchart shown in FIG. When the cost estimation system starts, the following messages are displayed on the screen of the display device 19: ``Quantity input'', ``Correction'', ``Breakdown print'', ``Analysis'',
A menu corresponding to "Data save" etc. will be displayed (
Step S1). In the next step S2, one of the displayed menus is selected by operating the input device 16. Then, in the next step S3, it is determined which of the above menus has been selected. Here, if it is determined that "quantity input" is selected, the process advances to step S4, and if "correction" is determined, the process jumps to step S12, and also, "breakdown printing" and "analysis" are determined. If so, the process advances to step S15 or step S16.

[0008] In step S4, the equipment construction subjects are read out from the subject master base 13 and displayed on the screen of the display device 19, and in the next step S5, one of the construction subjects is read by code number by operating the input device 16. select. In the next step S6, it is determined what the selected construction subject name is. If this determination is not made, the process returns to step S4. If the determination is made, the name of the selected construction subject is determined. The material items are read from the material table of contents master base 14 and displayed on the screen of the display device 19 (step S7). That is, for example, step S6
The construction subject name identified in
If so, the material items related to the "water supply and drainage sanitary equipment work" are read from the material table of contents master base 14 and displayed on the screen of the display device 19. After that, step S8
