Thanks to everyone who replied. I will just wait for the final engineering report and update here. So far that's all I know about the piers and edge beam on garage side (built to boundary wall). I will ask re why not pier all over and why only one side. My soil test states : Classified as Class H2 in accordance with AS2870- Residential slabs and footings Predicted surface movement (Ys): 55-65mm Field moisture content ( % ) : 24.1 Fill Depth: Approx. 2.3m BH1 & 2.2m BH2 (Level one certification sourced) Soils: Refer to borelogs Foundation material: As above (all footings to be founded on uniform materials) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Please let me know what you think? What else I can ask once I get the engineer's report? What should I expect in terms of, for a waffle slab on a H2 or H1 what needs to be there. Total area is 242sqm for double storey. Thanks in advance Re: Site costs 19Apr 23, 2020 1:46 pm there should be information from the lab on the soil sample analysis (as they have sent 2 samples to the lab according to the above). Based on what they classify it as H2? But nevertheless, it is FILL clay sample which is classified as H2, so you really can't be H1.

I didn't get copy of the lab result, I can't see it on the soil test result. It says on result on the basis of the site investigation including bore logs, dynamic cone penetrometers and NATA Accredited Laboratory analysis the above site may generally be classified as Class H2 I will wait what is written on the engineers report and go from there. I won't sign the contract until I am satisfied with the slab specification.. For a H2 on a waffle slab, do I need piers on all areas? I have been searching online, it says to ensure stronger, deeper, and stiffer footings but what does it usually involve? Thank you Henley should give you some indication of site costs. Too many variable to give you any reasonable accuracy 1 14677 Hi El Forgo From what you are describing, I would be budgeting at least $6,000-7,000/sqm at an absolute minimum, possibly even $8,000.
