Re: newbie question about floor joists, maximum spansGeneral Discussion

Sorry for the late reply, but I didn't realise the conversation had kept going. In the end the engineer insisted the builder retrofit sisters to every second joist. The engineer then signed off on the variation and all was well. Thanks for all the great replies. I now know more than before about fra...

OK, lets throw the rule book out the window. If you fixed another one of the same size next to every second one it would probably sort out any bounce problems.The additional one wouldn't even have to be sitting on the top plate,as long as it was within 50mm of the plates and glued and gunned to the...

Thanks oldchippy. This is excellent stuff and exactly what I hoped to get from this forum; real-world advice from the e...

Ok, it sounds like I should press the builder to strengthen the floor. Probably by sistering the joists to make them strong enough to handle 4.8m spans. Thanks for the advice.

The joists are overspanned,it won't sag,but you will feel bounce,especially if you are seated and someone walks into the room. Will the building inspector pass this?what was on the plan? I'm relieved you say sagging wont be a concern. That's a silver lining. The engineering plan had the joists orie...

newbie question about floor joists, maximum spansGeneral Discussion

Apr 28, 2013 3:13 pm

I've a quick question about floor joists and maximum spans. I've read the span tables but also interested in real-world and long-term experience from framers/builders. Got a second-floor lounge room. The floor is a single span of 4.8m. The joists are 200x45 LVL15 (equivalent to F17) with 450mm on ce...

Re: double-hung vs awning; solar-passive vs practicalityWindows & Doors

Jul 02, 2012 6:33 am

nhand42, how many degrees off north do the windows face? I think if you're talking literally NNE or 22 degrees then you're outside the ideal orientation anyhow. I reckon your safety concerns are a valid reason to compromise, if infact it is a compromise. I've heard different things about the pros a...

Thanks for the thoughtful reply. Yes, the windows are precisely NNE and your point about it being a compromise to impro...

double-hung vs awning; solar-passive vs practicalityWindows & Doors

May 20, 2012 1:37 am

I have a solar passive house design and I'm a few weeks away from starting the build. I have a question about some window choices I've made. The window brand is Vantage Magnum. The windows in question face north-northeast and the prevailing winds are north-west. The build is in Canberra. The archite...

Re: Electrical Engineer allowed to do Electrical work?DIY, Home Maintenance & Repair

Jun 08, 2009 10:58 pm

An Electrical Engineer is not trained for the practical application in carrying out domestic or commercial electrical work. We know that. Always amazes me how people think a theoretical knowledge overules a practically gained one. And we know that too. Nobody thinks theoretical knowledge outranks p...
