I have just received my soil test report. Our builder had placed 15k towards site works as it will require cut and fill due to a slight fall (a metre or so).
The soil test in 3 sites reports moist soil , brown clay and they recommend placing drains similar to agricultural drains in order to divert the surface and subsurface water away from the footings.
They have summarised our soil as class P due to existing house (which we plan to demolish) and some tree roots (recently cut). We are in Melbourne- Eastern suburb.
Please let me know if anybody has been thru a similar situation and cost effective ways to go about this. How much more should I add to my estimate for the site work?
looking forward to your feedback.

I've just posted a related question on the forum. I'm interested on who you are building with? Did the soil report give you any recommendations about the slab etc? If you check my posting, you'll see what I mean.
15K is reasonable compared to some of the amounts being quoted.

You seem to be going through the same sitn as us, Perry. The builder we are dealing is Metricon. I also went thru another consultant of theirs for a different home on our block who recommended p class slab right at the start with slight cut an fill (as opposed to larger amt of cut n fill to the house we later chose).
They have classified the site as P class (due to tree rts and demolition) but the slab recommended is M class (good news?) and special note on compaction of non porous filling (concrete?) in holes left from excavation of old house, roots etc.
cost wise the previous consultant (who was very patient in explaining to a newbie like me) accounted to about 18-20K for a p class.
I now wonder what I will be told
Class M slab + drains+compaction--- exceeding 15K
Class P slab +drains + less excavation--- 20 K
or combination of both-- $$$$$$!!!!!

I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills.

The appropriate slab is the one that the engineers design based on the report. In Short, yes. Is there things you need to be mindful of? heck yeah. Take a look for…

yeah obviously its ideal if you can work it out direct. But the suggestion of legal was in contrast to the suggestion of blocking the pipe. If you get to the point where…
