Re: Frames without timber noggings? 35Sep 04, 2017 11:41 pm Tom P It seems everyone on this forum stubbornly opposes any form of innovation unless it has been pre-approved by the government. Are you seriously suggesting that unapproved non compliant materials and/or products should be ok to use? The National Construction Code (NCC) and the Building Code of Australia (BCA) are performance based which allows for new technology and innovation. The Government provides the legislative framework which also denotes hierarchy but it is industry experts who provide the certification to have innovations approved provided those innovations meet the Performance Solutions of the BCA which is Parts 1 & 2 of the NCC. The OP hasn't replied as to whether a certified Performance Solution as provided for in the BCA was used. Ethically, contractual Performance Solutions should be brought to the attention of the new home buyer by the builder pre contract signing or else found during the pre contract signing examination and discussed. Many certified Performance Solutions are nevertheless introduced as nothing more than hidden cost saving measures. Unethical builders and tradesmen would have a field day if they were allowed to use non compliant materials, products or design measures as Tom P has suggested be allowed but don't think that it doesn't already happen. If the OP's frames were not a certified performance solution or do not comply with the Australian Standards, then they do not meet the code and are not compliant. I think that just about everyone on this forum would agree (as Tom P has noted for the wrong reasons) that non adherence to the code and the use of non compliant materials and products is wrong. Tom P When builders started using 110 bricks was everyone up in arms about it? OMG has this been approved by the government!! Don't use any new construction unless the government has legislated it!!! Then builders started using 90 bricks. OMG the government literature only says 110 bricks, your house is gonna fall down!! You are saying that houses use to be built without existing government approval, can you substantiate your claim? Tom P Timber houses used to be built using only jarrah. Was everyone complaining when builder's started using pine? Where does it say in the legislation that builder's can use pine!! Get your builder to rip everything down cause I can't see where the government says we can use pine!! Legislated codes and Standards states criteria which must be met. No secrets there, have a look. Tom P It's just a fact that the BCA and standards lag behind innovation by DECADES. The BCA was formulated to accept innovation provided such innovation is certified to meet the performance requirements of the BCA.....and that is a fact! Tom P And if an innovation has been tested and patented then it is AGAINST THE LAW for government to add it the the BCA. Yes you read that right. Patented new innovations CANNOT BE ADDED TO THE BCA OR TO ANY STANDARDS. Why hasn't Solarspan been added to the code?? What law? Do you really expect SolarSpan or any other proprietary products to be specified in the BCA or in the Australian Standards? Houses are built using SolarSpan, it meets the code.

Re: Frames without timber noggings? 36Sep 05, 2017 9:45 am Tim65 Thats nonsense, mate ".... hence my comment about a independent inspector especially if the op has limited construction knowledge You don't need a engineer to quote As1684 requirements , if the builder knows things are getting checked it might keep him on his toes" The codes are quite simple if the builder follows AS1684 then it will be compliant... no need for an Engineer If it's non-compliant then you better find an engineer to check & sign off on the structure according to AS1720 Timber Structures, where it will have to be certified equivalent or better than what's specified in AS1684.

I think this discussion has raised a few very interesting issues - such as what is defined as acceptable industry practice, and how far can we take innovative methods and "green" and "alternative" solutions, and what is deemed compliant and by whom??? As a person with very little experience in the industry, I find it difficult to get my head around what is and what isn't acceptable, and how that's determined. There also seems to be a lot of gaps in the interpretation of BCA and other standards, and the industry seems to be mostly "self" administered/governed. I have read through relevant bits of AS1684 and done a lot of research on this. The issue I see is that the nogging bits in the code don't specify whether they need to be "traditional" timber noggings or whether they can be metal "ribbon noggings" or other alternative solutions. It also doesn't state what may be other alternative nogging systems (as stated in earlier post, I did find a research paper published by a Melbourne uni years ago on the various noggings systems used and their stress-bearing effectiveness, which mentioned that builders in Australia did apparently use metal ribbons noggings at some stage in history). So if the metal straps system is considered equivalent in structural terms as the traditional timber noggings, then are they deemed compliant? No one seems to know... As a layperson, I guess I can only take comfort in the fact that: a) the frame fabricator has assured me that those frames are complaint (although I have not sighted any paperwork to this effect), and b) we have managed to get some traditional noggings put in as additional support (although we need to pay). As an update on costs: so far the builder has not issued the variation on the noggings and we are hoping that given not the whole house had to be done, the final bill will be less than the $2K estimated. Let's see. As a consumer, I can say, though, that I feel gypped about not be told of the "innovative/alternative" solution frames that were to be used by the builder at any stage throughout the quotation/contract negotiation/build process. But that might just be a "communication" and/or business ethics issue with my builder. It doesn't definitively rule out the fact that the frames used may (just may) be deemed compliant to code. I still feel gypped, though.. It seems that so far no one else has come across a similar framing system or these issues, so hopefully this discussion would provide some poor bugger, like me, in the future with some useful advice and insights.

I'll try to precise it to the basics. At the compliance level as seen in the BCA hierarchy pyramid that I posted in post 23, you will see that Prescriptive Solutions, otherwise known as Deemed To Satisfy (DTS) and Australian Standards, are on the left and Performance Solutions aka Alternative Solutions are on the right. Being on the left or right means nothing, they are both on the same level of hierarchy. There are no definitive "Green Solutions" but a Performance Solution can obviously be green by personal definition. To be certified as compliant, a Performance Solution must be proven by an industry expert to satisfy the BCA's performance requirements which are above it on the BCA hierarchy pyramid. Because your frames possibly/probably don't satisfy the Australian Standards, they have to be certified as a Performance Solution and have current certification. If not, then they are not compliant because they don't meet the code unless something that covers their compliance is also mentioned in the BCA or else referenced in the BCA to another Standard. Note that I haven't checked the BCA and framing is also well outside my area of expertise but many things are also mentioned within the BCA. You can download the 3 Part NCC free of charge, framing is covered in Part 2. The builder should provide you with proof of compliance should you ask for it. Being told that the metal straps are greener is BS, sequestering carbon is greener than using metal straps and pine is a plantation timber. The BCA can be vague and not always interpretation defined in its attempt to be flexible. This allows opportunistic interpretations that has brought it into public criticism on different occasions, I have previously posted comments on Homeone about criticisms made in the NSW Parliament several years ago about the BCA during the high fronted guttering fiasco and there have been questions asked about its role in the current non compliant building cladding investigation. 3in1 Supadiverta.
