Looks like it, the only time a 6m cut would occur it if the builder cuts straight between those opposite corners.
But if you have got the DA drawings and…

I think you have it about right.
Not sure how it is so wrong-perhaps he as seen the building envelope and mistook for site boundary?
Any excavation will be shown on…

I am assuming it was via a cdc. Could be I'm wrong and talking nonsense though....

The builder has gone via a cdc which is quicker and cheaper but has tight restrictions on landscaping/retaining allowed especially near boundaries. His ,portion of the contract is complete and…

Another issue with piers through the fill is that you would require a dedicated piling rig which may have issues setting up on a pool full of rubbish-it can be…

If you have the money and it’s a ridiculously cheap bit of land, get a geo-environmental engineer to provide you a quote to make an assessment of the fill so…

Hi,
Have you looked at this avenue as an alternative? Often if a straightforward reduction in scope it 's a cover letter and modified drawings and no re-application process.…

I'd wager there are multiple cheaper/better ways to construct a slab/footing that aren't as per the standard design provided in AS2870. But better/cheaper for who?
For the client-yes
For…

Piers are usually installed to transfer slab/footing loads to stronger material below the depth of shallow footings, normally due to the thickness of fill or weak soils although this is…

Not sure if you have tried quizzing SW about what size it should be rather than asking them if they have any records of it but there is an e-mail…

Check your local council DCP and LEP requirements if you haven't already. Some councils apply tight conditions when changing elevation near shared boundaries, so DIY may not fly-even if only…

Yes but if the region has a seasonal influence depth of a couple of meters replacement of a meter can significantly reduce estimated shrink swell movements.
As to whether…

It would be worth asking the geotech to provide the depths of clay which would need to be removed to reduce the estimated shrink-swell movements to that of H1/M/S site…

So where is the soil test these recommendations are based on? Where is the pond in relation to likely house location? Now much fill is present? etc etc

Hi boris594,
It’s unlikely that the structural engineers are working with the builder to extract the maximum profit. Designs must be approved, and most…

Hi,
Is the site sloping and are you digging out material to lower the ground level or just digging for new footings?
If bulk excavation to lower ground level, rock excavation rates…

Hi,
Seems you would have a case to ask the builder to remedy this-Have you approached them yet/had a look at the drainage requirements?
Failing that and assuming you have some…

Hi,
A free draining gravel/aggregate layer needs to form part of the backfill to the wall which feeds into a drain/weepholes at the base to dispose of water. It's pretty…

Hi,
The recommendations of AS2870 are pretty clear as well. I wouldn’t panic about it but if the builder can’t construct to the standard, he still has an obligation to keep…

Nah, soils don't magically compact themselves.
Not talking about driveways-seems the phrase is used when excavations are filled up with course single size gravel with no fines. Pour it in the…

Mmmm,
Not sure if it is strictly an urban myth, but:
'Self-compacting gravel' is a phrase I've heard a few times.....

Doesn't sound like a huge cut-They may be intending to build via a CDC application which does limit cut/fill depths on site but as the approval route is quick and…

No doubt if plumbing requirements as per AS2870 are specified on the structural notes they should be followed. But that relies on individual engineers referencing AS2870 on drawings. If…

I understand what you mean now. I'd imagine it's difficult enough trying to claim for heave induced defects without one of the main 'suspects' having the rule book…

Always a fly in the oinment....
I'm not sure what the loophole is? To me it sounds like poor earthworks and uncontrolled surface water/seepage. These should be picked…

Interesting discussion
I'm not familiar with the legal ins and outs but the requirement to grade the site and divert water away from footings/settlement sensitive areas, prevent ponding, remove any…

Perhaps it's my lack of understanding about waffle pods-write it on the back of a stamp....
I thought waffle pods could absorb a certain amount of movement but not differential movement?
I'm…

Possibly because of abnormal MC in future- trees, faulty drainage I guess. Not an existing condition though.
Seems.....pessimistic. 14 cube of concrete for some possible future roots? Is there…

It doesn't seem piers would be needed here at all-pretty decent ground by the looks.
No idea why those piers are left-if a root barrier of sorts, contiguous piers would be…

Where was the original retaining wall going? Where I’ve indicated in blue about?
Additional removal of landscaping (or is that a low retained pathway?) is also indicated at the side…
