One builder suggested that I get a soil test done even though the existing property is still there. I prefer a soil test after the demolition though does it matter? http://boostaoakfordsa.wordpress.com Site works: 26/8/14 Trench: 2/9/14 Slab: 8/9/14 Frame: 18/9/14 Bricks: 24/10/14 2nd fix: 24/11/14 Handover: End Feb 2015 Re: Demolition / footing questions 5Jul 29, 2013 12:11 pm Definitely. Soil test after demolition. As previously mentioned the soil report should come back as a class P due to the variation in soil moisture content between the the exposed soil & the currently covered soil. Generally if the site is allowed to 'sit' for a period of time after demolition the soil profile will level out. Ideally it would be good to allow the cleared site to sit for 6 to 12 months but this is not always feasible.

Re: Demolition / footing questions 6Mar 19, 2014 9:34 pm Just received my soil report and it does not look good - site classification - E-D/P (fill). Soil assessment - the soils on this site consisted of at least 550mm of fill overlying highly reactive clay horizons to the extent of testing. 3 boreholes taken and the current house to be demolished is still at the block. Came back with grillage raft (I searched but not much on forum). Beam A (900mm depth)/ 250mm / 1N32 (top) / 1N32 (bottom) / W8@1000 (hangers) Beam B (900mm depth)/ 250mm / 1N28 (top) / 1N28 (bottom) / W8@1000 (hangers) Slab 120 with SL92 Builder's standard FOOTINGS EXTERNAL: 450mm X 300mm reinforced with 6/N12 bars INTERNAL: 450mm X 250mm reinforced with 4/N12 bars SLAB: 100mm thick with 1 layer of F72 mesh Will ring to find out how much extra I have to pay.

Is this too good to be true (price-wise) for single storey 174m2 total living?
