As to what part/parts of AS 2870 applies to your contract and construction needs to be perused by the solicitor. This is important. State variations can also override the NCC and AS. The NCC sometimes criss crosses the AS, it can become confusing but it has to be remembered that in the event of a conflict between the 3 Part NCC and a referenced AS, the NCC, as the primary document, has hierarchy but a mix of the two can also be used! Wow SaveH20, its no wonder there is the ongoing problem of slab heave when there is such a convoluted approach ... Why does NCC even try and replicate / duplicate standards such as AS2870 ? This will just lead to discrepancies and confusion. For example: NCC 3.2.5 does not include H1 and H2 soil classes (it only has the original H class) The deemed to comply designs in NCC Table 3.2.5.5c don't match AS2870 NCC doesn't cover waffle slabs. On this last point, since waffle slabs are not covered then do these NCC 3.2 provisions come into play Appropriate Performance Requirements Where an alternative footing system is proposed as a Performance Solution to that described in Part 3.2, that proposal must comply withโ (a)Performance Requirement P2.1.1; and (b)Performance Requirement P2.2.3; and (c)the relevant Performance Requirements determined in accordance with A2.2(3) and A2.4(3) as applicable and Performance Requirements P2.1.1 and P2.2.3 are satisfied for footings and slabs if they are installed in accordance with one of the following: (a)The footing or slab is constructed in accordance with AS 2870. (b)Piled footings are designed in accordance with AS 2159. and as a result AS 2870 including Section 5 of AS2870 are now in play. I must say it seems a bit sad to need legal advice for the correct specification of a residential slab. Speaking of legal advice here is high profile case of slab heave that Metricon lost http://www7.austlii.edu.au/cgi-bin/view ... 4/277.html Re: Slab heave nightmare. I don't know what to do- please he 10Sep 21, 2020 1:38 pm It should be noted that Australian Standards are produced by Standards Australia, a non government not for profit organisation. The NCC is a performance based document that references many AS as Deemed To Satisfy solutions but where AS 2870 is concerned, it deals with plumbing and construction whereas it may not be referenced for both in the NCC. The NCC, being performance based, allows for new developments and techniques to be used as Performance Solutions provided they are certified as meeting the Performance Requirements of the NCC. Many people also do not know that several years ago the NCC dropped acceptance of manufacturers recommendations for installation etc of their products. New home buyers are disadvantaged by the builder lobby group's standard contracts but they don't realise this until a construction issue arises. 3in1 Supadiverta.

I don't know what to do- please he 11Jan 02, 2021 12:18 am In case anyone is interested in my situation, I have engaged a solicitor as the builder ended up claiming that he is not responsible for what has happened to my house and that the damage is my fault due to (according to him) overwatering of the turf. The turf was laid in April and I have emails with accompanying photographs that I sent him also in April where I describe my concerns with all the cracking and movement that was occurring and in which I ask him if such is normal. This email was ignored at the time. The turf was watered in line with the recommendations given to me by the builder and the gentleman who installed the sprinkler system however the builder is making ludicrous claims like I watered the turf for "well in excess" of two hours per day, every day for months on end which is an outright lie. Of course I have my water usage on my council rates notices which clearly indicate that what he is claiming could not possibly be true. The builder, through his solicitor has recruited a hydrological engineer to "confirm" that the damage to my house was caused solely by me and my alleged overwatering of the turf. He has offered to perform some very minor rectification work provided I enter into a deed of release which I am not prepared to do. Acting on my solicitors advice, I have lodged my case with NSW Dept of Fair Trading and assuming that leads nowhere, we will be lodging at NCAT after that. It looks like I have a long and expensive legal fight on my hands. I will keep you all posted. Re: Slab heave nightmare.

Re the 'path'...the builder had it installed at a non compliant height (see my prior post) and without a spoon drain or similar. This has allowed water to pool at the path's edge. Also, the 'path' looks like pavers (are they?), is too narrow and not conducive to good drainage. It was a cheapskate effort. Also record the path's depth and how the base was constructed.

Have you had the stormwater and drain (DWV) pipes forensically examined by recorded CCTV? Thank you for your response H20. I appreciate you taking the time. I recently paid $3500 for my own engineering report and I am still waiting on receiving this. The process has been slow due to Christmas holidays etc. The engineer did pick up on the issues with the pathway as you kindly pointed out to me in a previous post. The path is not pavers, it is concrete. Yes, when the engineer did his inspection, he brought a plumber with him that looked through the pipes with a CCTV camera and did not observe any cracking or other issues. He did mention that at a certain join, a "knuckle joint" was supposed to be used but had not been. To be completely honest, I couldn't tell you what direction the rain usually comes from. Thanks again. Re: Slab heave nightmare. I don't know what to do- please he 14Sep 07, 2021 10:19 am Adman SaveH2O "Minor rectification work" will be a short term cosmetic cover up.

Thanks again. Hi Adman, Now I got same issues like you. I built my new house three years ago in Melbourne. I found many cracks on ceiling and wall few months ago. The builder inspected my house and then he said I need to remove footpath and reinstall because it hasn't proper angle according to Victoria building regulations. And then he needs to monitor the house heaving. So I asked him if I replace the footpath, is the slab heaving going to be steady? But he never answered about my question and keeps talking about other things. I'm so frustrated now. I just need a clear solution about my problems. Can you share your situation with the builder at the moment? Now I'm seriously looking for a legal adviser about my issues. Thank you Re: Slab heave nightmare.
