How is the edgebeam depth determined?
As far as I know, edgebeam should reach founding soil with acceptable bearing capacity, according to soil report it's 200mm below ngl. Waffle slabs are used in this project and the slab depth is determined to be 385mm.
As per the cut and fill, our cutting line is determined to be at FFL 100.5 and the level at the house adjacent to SW pipes are 100.7, so we cut existing fill there by around 200mm.
So cutting 200mm will expose the 200mm deep founding soil. Since it's already on founding soil, how far down should the edgebeam go?
I want to check for undermining that's why I want to know.
VIC project, H2 site.

The depth on reactive clay doesn’t necessarily depend only on bearing capacity but also depends on the site reactively (the upward movement of clay soil). H2 means it’s highly reactive soil. You should also allow for a pad under the waffle slab as it may have been specified I guess in the engineering plans. Hi all. I have a drop edge beam down the left side of my house.
