Browse Forums General Discussion 1 Feb 25, 2024 10:17 am Hey folks, We're knee deep in QBCC mediation due mostly to the movement in our house. We are slightly raised on a gently sloped block, one corner filled/the other cut. We have steel adjustable stumps. Just an idea of the amount of shifting: we have a building report stating our deck has a 30mm drop over 3m, a 20mm hump in the floor, 20-25mm drop in one corner of the bathroom. Our back sliding door won't close and has a few mm gap at the bottom, leaving it open to insects and unable to be locked. The builder's opinion is that this is caused neighbouring builds that went up after us have cuased changes in water flow and moisture content of the soil, and rust in some piers due to lack of owner maintenance. However... I've just noticed the the engineering plans all have a little section along the bottom stating the home was designed for Class S soil types. We are H2. Is it likely that a) that was a template inclusion accidentally left as-is, and the calculations have been adequately done for H2 soil; or b) that the stump design would not be significantly different between the two soil types? We also noted that a soil compaction report was not done, which was listed in the DA. Is it reasonable to assume that it doesn't matter, because the bottom of the sump is on natural ground (and therefore the support from underneath being the only relevant factor), despite the surrounding soil being fill? Would the council dev team be able to answer that for me in a phone call, or tell me to contact the builder/surveyor? Just trying to get ahead of it all before our next mediation meeting on Tuesday; My understanding is that we get one shot at this, then it's up to the QBCC inspectors who may just wash their hands of it and blame the neighbours. Re: Steel stumps, S vs H2, house movement 2Mar 04, 2024 7:26 pm Are they stumps or screw piles ? How much fill is there, is the site a class "P" ? A "H2" site is not supposed to have stumps it is supposed to have grid beams according to the Australian standards. House movement is always a potential problem and there is a cause. Yes you should have it inspected by a competent and experienced building consultant 2 8899 Have look at your house plans and you will probably find that brick articulation joint has been missed. Maximum allowable spacing is 6M or 5.5M for a wall with window… 17 20957 10 4748 |
