In short: What a reshaped site means for your slab, and what the soil report actually tells you.
The history
Oran Park Raceway operated from 1962 to 2010. The town that replaced it sits on land that was cut, filled and regraded to create it.
What that means
Ground conditions vary lot by lot, between cut, natural ground and engineered fill. None of that is unusual and all of it is designed for.
What the soil report does
Classifies your lot under AS 2870 and gives the engineer what they need to design the slab. It is the single most useful document you can ask your builder for.
Why we will not publish a class
Because a suburb average would be meaningless here, more so than anywhere else in the area.
What to watch afterwards
Drainage. On clay and on fill alike, keeping moisture at the footings even is the thing an owner actually controls.
