Soil tests and re-establishment, feature and level surveys

So no second soil test after demo, no changes to the original engineering design regardless and no inspections !!!!
Maybe save all that money for the repairs and a lawyer.

Battlers and punters are sick of their houses cracking and failing because their builder takes short cuts to save dollar.

If you have clay in your soil profile then most likely you will end up with a class "P" regardless when you remove the tree or leave it.

except that it is required by AS2870.
Piers are part of the footings

Digging under house slab

You must be careful when you say this as it is not the case for sand.You will need to know the depth of the slab and the soil type.

It is uncommon to be poured as one.A good question to ask the builder is how did they do the plastic membrane ?

Make sure you include a properly constructed protective concrete path in your budget.

Grade A soil - any downsides?

No downside on the engineering, this would be my preferred soil type to build on except may be difficult to keep the watering up for the garden.

Unfortunately you are on some of the most reactive soils in Victoria you must be down Geelong way. Was the house built in 2012 or earlier?
