Advise me please, what value of datum (z) should be on the left side of the tab "Imported load" in Lira-SOIL. I mean, benchmark of design scheme in VISOR-SAPR. If the foundation in VISOR is at the level -3.5, do this number should correspond it? Just set datum on the right, i.e. benchmark in soil model 115.8, and the number on the right automatically established at 35.8 m, i.e. this is top of the building. How to be in this situation?
