Sorry,
I forgot about this post.
Generally here, the roof trusses are erected before we even set foot on site.
the cieling runners are run at right angles to the trusses and are nailed to the bottom chord of the truss.
This is what the Gib (Gypsum) board is nailed to.
The problems start when an Architect specifies that all the light fittings (all recessed R-95 Downlights) have to be placed where stated in the Electrical Location diagram, even when told on site that it just won't work.
Under ECP53 here, light fittings of any type have to be distanced from timber by at least 100mm (4"), that I have no problem with.
As a FF, I agree with it.
But when Architects start telling you to cut bits of the building Structure out, I really lose my rag!.
It's un-necessary and should not be happening.
Sure, I have have tried to take the tack of Pauluk, but, oh no that is the way they planned the lighting.
Just a shame that these young idiots can't design a roof to save themselves.
If I did as they said and cut the runners to bits and the cieling collapses, who carries the can then?.
After all we are sub contractors on these jobs.
Sorry about the rant guys, but I take real pride in a well-done job, without compromise.
