OK, I just came down from our roof with pictures.
I don't know if our roof is a different 'type' to Arc's or whether I just had no bloody idea what i was looking for.
But I attached the pics anyway.
I couldn't find any steel beam that resembled Arc's.
All the beams seemed to be supported by steel connection/clip thingy's???
(Please excuse my ignorance with this, I'm still trying to get a grip with it all)

madrat, your roof uses a 'truss' type construction.
As such it is not likely that you'll find steel members within the roof space.
With a 'stick' type construction beams, whether steel or timber, are often used to span large distances and in turn support other roof timbers.Peter Clarkson

These are the issues the building inspector highlighted;
- To comply with BCA AS1684; Bolt or shot fire at max 750mm C/CS WBN / Structerre Concession (at present Tek Screws used) - this is for timber plates on top of UB's.
- Raft Ridge collars not in.
- Hoop iron straps are loosely nailed to rafters. No attempt has been made to tension straps. Not fixed to purlins (battens). Suggestion to disconnect straps and 2 x nail to the top plates plus triple grips to fix rafters to plates.
- Porch and Garage; Plates are not strapped. No soldiers.
- Under purlins where overlapping and sharing a prop should be bolted together (2x).
- Alfresco plates on RSJ's are strapped to RSJ (one elevation only!) but rafters are not triple gripped.
- Props seated on lower flange of RSJ need lateral support.
PS to Madrat - you might want to consider getting some insulation installed.

And not a mention of the loose brick stack?
Must be ok then...?

This was the primary reason I had the inspector out and I specifically highlighted it to him onsite and discussed it. He told me it was ok and acceptable.
As I said earlier, I don't expect this to be changed in this case (unfortunately) and accept that this is the sort of thing that is being done in WA. However I do not believe this should be acceptable practice or allowed by the building codes, as it appears it is (possibly because it is vague in this area) then those codes need to be changed or clarified.

I did have a flick through both the framing standards (non cyclonic) and the brickwork standards but couldnt find anything, maybe its in the steel standards?
Its still bodgy in my mind though.

Are the triple grips compulsory?

[quote]Porch and Garage; Plates are not strapped. No soldiers.[quote]
What is a soldier? I assume he means kickers?
Strapping plates? Does he mean the wall plate?

How do you get a hoop iron strap from the cavity up to the under purlin?
They're not even delivered long enough.
Where was the inspector from?
This is a Truss with gang nails. Different
c2=a2+b2;
When buildings made with lime are subjected to small movements thay are more likely to develop many fine cracks than the individual large cracks which occur in stiffer cement-bound buildings. Water penetration can dissolve the 'free' lime and transport it. As the water evaporates, this lime is deposited and begins to heal the cracks. This process is called autogenous healing.

We were going to get insulation, but we are getting the roof repaired and repainted with insulpaint (apparently this paint will make a massive difference to temperature and air con usage to the point where we may not need it. So we'll see if it is right or whether we have been duped).
Cheers and good luck. I will continue to follow this thread, that's for sure.

If there were more people who wanted to know & learn it would probably make my work easier overall.

Why dont you email the WA institute of building surveyors [email protected]<SCRIPT language=JavaScript type=text/javascript> <!-- document.write( '<span style=\'display: none;\'>' ); //--> </SCRIPT> with some pics, and mention that you have heard this is common practice. See what there comments are.
