How deep do builders usually cut the site to construct the slab on site with rock? I tried searching online but there isn't any information about this.

Albert142 The minimum required to accommodate the floor slab. I think you only need 100mm for the slab thickness but 300mm for footings at the sides to comply (this can only be done on a Class A site). But the 300mm is detail excavation not cut so it's a curious e-mail. Who ever did the soil report really has done the minimum required and left unanswered questions. Don't suppose you are allowed access to the site (armed with a 10mm diameter steel rod and lump hammer...) Re: Soil Test - Rock Found 5Oct 09, 2020 5:03 am worldofmud Oh okay. No, I am not allowed access to the site, as it is unregistered. We were given access only due to the soil test clause in our contract.

I will have a talk to the builder and see what they have to say about this. To be fair to the soil testers, they have done what they were asked most likely. I looked at the borehole locations from a geotech. investigation point of view and the locations would be inadequate for that type of investigation but pretty standard for a residential soil test. It's likely the builder who requested this level of works, and site class to AS2870 is the minimum required to satisfy DA/building requirements, but not normally the required level to control costs on any site never mind a rock site. If you do contact the builder, perhaps query if there would be a difference in price (to you) where a site is classed A rather than S. . We were lucky in that our old house was so small (86 square metres) compared to the new house, they were able to take enough readings around the old backyard house before… 8 37139 Three options 1 Ask the liquidator 2 Find another PD customer and ask the source of their report 3 Pay for new report 3 12332 Hi Building Expert, Thank you for the feedback, much appreciated, there is also a code of conduct for building surveyors which they need to follow as well.
