I can't. Furthermore, in the building illustrated in FIG. 4, the rescue weight 7 cannot be stored on the rooftop floor, so it is necessary to carry the rescue weight 7 to the rooftop floor via the vertical trap 1 every time the control panel 5 is maintained and inspected. Inconvenient.

  As described above, the maintenance trouble occurring after the construction of the building and the design conditions of the building are related to each other. Conventionally, whether such troubles can be avoided at the design stage before construction of a building depends on the knowledge and experience of the designer.

In the example of FIG. 6, three check buttons Z provided to correspond to the three countermeasures are displayed in the area Y. The user changes the design by adopting the countermeasure displayed in the area Y of the screen IM1, and then performs an operation such as pressing the check button Z corresponding to the countermeasure, thereby performing the countermeasure. The area Y can be erased. That is, the check button Z is a button for confirming whether or not trouble can be avoided.

  In the first embodiment, a trouble information display screen may be displayed in which a countermeasure most adapted to the feature of the integrated BIM model is highlighted in the countermeasure list. That is, the trouble information display unit 102d according to the first embodiment may display the following trouble information display screen instead of the trouble information display screen illustrated in FIG.

  FIG. 7 is an exemplary view showing an example different from FIG. 6 of the trouble information display screen according to the first embodiment.
