Photo reads sideways taken underneath so that space I'm referring to is vertical ie perpendicular to the wall. Came about as that part of the roof was changed on the fly due to a drafting error.

The supporting wall, is there a gap between the wall below and the truss above? Did you take a photo without the insulation..just curious BTW,Quite often when draftsman make mistakes the on site solutions need to be checked as the trusses are fabricated off site for a specific use and load combinations.

You might need to explain it plainer than you already have. This pic is of the roof, so a void was created over the stairs. There are two planes to the roof visible in that photo, the exposed part where they haven't put insulation is the vertical rise coming off the plane of the roof to make the void - does that make sense? So talk to me like an idiot - which wall do you mean and what gap? I will try and get some more pics tomorrow. I think I have pics without insulation will try and find some.

They've insulated the house but left this vertical rise off that plane of the roof where the void is empty, which seems wrong to me.

It's upstairs, about 9 risers. The second one shows the truss that has no insulation on it in my first pictures. Not great pics but all I have.

So therefore it will need to be inspected. For others, basically trusses are designed to be 1. Simply supported at the ends 2.

Did he supply you with Details, Specifications, correspondence in writing, etc simply saying its compliant doesn't make it so? 3. Well I would be asking for proof and a certificate of compliance. BTW the first of the last lot of photos you put up showing the truss supports is not acceptable IMO, the onus is on the builder to prove that it is. Your choices now are, 1. You can self assess the work (given the right tools ) for compliance against the codes, cheapest option or get someone in most expensive option. 2. contact your local council building department and ask for assistance with non-compliance matters 3. Hire an engineer to deal with non compliance.

What specifically concerns you about the pics so the PC doesn't brush me off? Are you saying there is not adequate support for the truss that is there? I've sort of taken one photo of one side of the void that faces the street and turned around and taken a photo of the other side that faces into the house if that makes sense.

Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Re: Insulation q 13Jan 31, 2016 7:35 am I think your frame is poorly set out because basic skill of frame set out is to mark your truss points on your top plate and ensure there is a stud under. In the case of concentrated load there should be at least a double stud. Your photo shows trusses sitting on double plate between stud and then what appears to be a major concentrated load not having a double stud under.I have marked your photo to show you http://i1321.photobucket.com/albums/u559/brankom10/9a20d4089004ce372255a7b03b4e7607_zpsuv2dvqie.jpg Your framing structural drawings should show a double stud in the location of my yellow arrows. As for insulation it must be tightly fitted. In my final home inspection I use thermal imaging camera and invariably it will pick up areas where insulation is missed or poorly fitted because heat is coming through.

Shouldn't he be looking at the plans?!! Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Re: Insulation q 15Jan 31, 2016 11:34 am Hi Leskie5000 Do you have the engineering Drawings? They should consist of 1.Wind category & soil report 2.Footing and slab details 3.Drainage Plan & details 4. Timber Frame and truss Plan details 5. Bracing and shear wall plans details 5. Timber Floor Plan details 7. Masonry plan and AJ details etc,.etc In total 15-20 Pages signed/certified/current by the Engineer? Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Insulation q 16Jan 31, 2016 11:41 am If there was a change and drawings were amended and re certified then yes certifier should be looking at the latest relevant drawings. However a missing double stud error is so basic that it should have been picked up even without drawings. I would not be comfortable with two trusses bearing on double plate between studs, and really there is no excuse for not having studs not lining up with trusses. At the very least I would ask for blocking. It is not enough just to satisfy structural adequacy, work must also be done in a workmanlike manner showing skill and care expected from a tradesman skilled in his art.

Well the drawings weren't amended it was a correction they did on site after it was identified that there was an error in the drawings. An engineer etc didn't sign off on the changes as far as I am aware and not sure if one should have perhaps. Does such an error represent a breach of the BCA? What do you suggest I do follow bim guys advice above? Fortunately my cousin is a highly skilled engineer and she can probably have a look in the first instance.

You can also approach the engineer I do not know if the architect drew up the change as the builder went back to him directly since it was his error. I sure don't think an engineer has even looked at the change?! As far as I know. It was a change from the approved plans.. There was always a void but they changed the slope of the roof Custom knockdown rebuild Newcastle NSW viewtopic.php?t=78271 Hey guys building a new place through a volume builder and just wondering if i should complain to the site supervisor as we just had plasterboard installed.
