an explanation of roofing framing for assessment

I cannot find the photos easily here to back up my work but I can show you on Drive. I am going to explain the times we have done roof framing and what we did. First of all you have to take delivery of the pre made trusses.  We have done both timber and steel trusses.  In both cases you need space to put them safely and somewhere where they will not be damaged or warped. Timber should be completly flat and wrapped after and steel as well. You then need a lift plan this should be a written and agreed about task analysis. With timber trusses it is likely you will need machinery to lift into place with residential steel trusses you could lift with manpower but a plan needs to be in place. The trusses will be marked out already usually 900 centres but we would Check the plans and specs. The best way of marking out is 922 x back and then 900 running measurements. I marked out the roof at the Warkworth primary like this over 30 metres. Once trusses are in place you will need to fix them off correctly and also temp brace them. Once trusses are in place the next step is to mark and chalkline purlins off the top off my head I think they are usually 600 centres but we would check the plan. Once purlins are all secure you can remove all temp braces and install any uplift and tie down hardware. Thought should be considered for any load bearing walls to also make sure they are braced and will not be impacted by extra weight and movement. We usually use blue screw purlin screws for timber and manafactured screws like Wurth screws for steel.

Framing

back to school

This week been down in Warkworth ripping down RAB board someone else put up that is always annoying. I worked with the main contractor and didn't get angry he ended up singing my praises we got new board up with next to no penetrations so the building is ready again now to pass the M O.E  Inspection, yesterday I framed up an Internal wall I used my new lazer to set up the top plate off the bottom and the top was fixed to steel beams with Wurth screws I then measured the studs and spaced them out at 600 centres and used lazer to quickly mark out nog lines at 800 increments.

I have been in Warkworth lately we removed the paper and nailed the rab board underneath correctly it was done wrong the first time.... I also framed up this wall I checked the plans, worked off a gridline and got the bottom plate in right place I then used my new lazer to find the points in top to put top plate and fastened to roof I measured the rake of roof with a digital level and then measured and cut each stud with  the 15 degree angle on it.  I also marked out the nogs but got called out to do the paper again. Sucks fixing other people's work.  But hey that's why I always check the manafactures specs before doing anything.
