The footings are M-class did the builder charge extra for Deep edge Beams &/or piers?
Fixed Site Cost... More info required what's included in the quote? +The next issue may be what's done on site
often the piers don't go in as specified?
Question will you get a credit, Who inspects the hole depths, Concrete, etc,etc
BTW, That is not the final engineering drawings.. that's worse case?
Please post back with your final quote & Engineering.hth
M-class Slab on P class soil
Page 2 of 2
Did they even do a soil test or did they infer. Because a Ys value of 20-40mm sounds suspect. My soil report has a single figure rather than a range that is exactly matching soil classification. Sounds like all they did is infer. Not good enough.
P just means your slab needs to be custom designed due to something unusual about the site. It is not strictly a soil condition grade. In your case it’s the fill. All KDR sites are P grade. But a separate soil grade still needs to be given.

In the report they have mentioned that they went on site on 23rd oct and did the soil test.
Is a M slab acceptable based on their assessment?
Hi bentleighboy
I relied on my builders geotech too.
When I asked him for his final report after house was finished he referred me to the builder.
And I read detailed report and it says I take no responsibility for anything.... blah blah.

bentleigh_boy, I PMed you the geotech engineer my builder used. They seem to be pretty good.
Thank you kirashogun, much appreciated. Will talk to them for sure.
Can I ask which builder you used and where did you build?
Hi Bentleigh_boy,
Our soil test is classification P due to KDR, but is underlying S classification. We get our contract and site costs later this month, but I am expecting a slab for S classification with maybe provision for piers if post demo identifies soil issue.

Have the fill/soil properly compacted and checked by your engineer, it will not require piers

Just got the prelim and they are recommending screw piles - 11.5k although they will be doing a further survey, hydraulic and soil test once demolition is done. My concern is they want to fix price the site costs prior to demolition and secondary test. Thoughts structuralBIMGuy ?
Unlikely to change if they already have recommended screw piles before knock down.Problem happens when they don't recommend deep footings after the initial soil test while the house is still there and then recommend deep footings with the second soil test after the knock down when you are committed.

Await the independent second test don't lock in piers. hth

I'm in WA and our sandy soils make drainage a bit easier but this is what I'd be doing. Dig down to your footings and let the wall dry out. Clean it all well by brushing…
