    Default Laying Joist ??

    Hi all I am building my deck at the moment and because it is half on concrete and half on dirt I was wondering if I can lay my joist on the 90 face down rather standing it on the 45 as this would make building the deck easier and I do know it would not be structural but i will add extra pieces of timber underneath each joist to make it stronger

    The answer is that a sensible answer can't be given with that info. You can pay a joist on its flat - but that changes the dimension used for working out a suitable span (it is now 45mm deep not 90mm). If timbre is directly over concrete is not unusual to lay the 'joists' as battens on the flat. So need much more info - or pics or a sketch of what is proposed.

    This question is exactly why the government brings in legislation to limit the work undertaken by owner builders.

    God I hope the same legislation limits the work that the builder reflexor is dealing with. Dont know if you have seen the thread in tiling. That guy has been put through hell by his so called "builder".
    I couldn't repair your brakes, so I made your horn louder.

    I'm an owner-builder (twice) and I spent a significant amount of my time on site explaining the BCA to some of the clowns who called themselves tradesmen that I employed. And that included the brickies Brickie.

    Nothing important mind you. Just missing reo in the footings, incorrectly constructed articulation joints, insufficient number of cavity ties, a brick wall that was 40mm out of parallel with its opposite, plumbers cutting thru the hoop-iron cross-bracing, roofers who've never heard of a spirit level. Trivial stuff

    Well no - it's a legitimate question and the BCA allows it under particular circumstances - so long as the timber in that configuration can carry the loads intended. As my earlier post said - not enough info was given to know the answer.

    Not at all, its up to council or certified inspectors to pass the work thats been done as being ok.
    I deal with hundreds of chippies and builders through work - a great number have no idea of the BCA regarding many aspects of the building trade and even less have any knowledge of timber grades, types, species or applications etc.
    I'm not throwing a blanket statement down, some are extremely professional and knowledgable in their work but many I'm scared are out there building people houses
