    Hello,

    Build has been progressing well since initial concerns with foundations, and brickwork is now up to roof level.

    Just wanted to check a couple of things on the ground and first floor fixing methods.

    Both floors are using timber trimmers / wall plates, with joist hangers for the joists.

    The method of fixing the trimmers/wall plates to the walls is 110mm * 75mm concrete screws with T30 heads. I read a lot of stuff about resin, M10 and M12 bolts, coach bolts, through bolts and a lot of other stuff, but not much about concrete screws being used for this kind of work. Which makes me a bit nervous.

    They're set at approx 400mm centres and offset alternatively above and below the centre line.

    The walls on one side are solid concrete block (not the aerated kind the builder has deliberately put in a row of solid blocks at the right height for the first floor, all other courses are aerated), and on the other solid brick (original 60's house, no frog or airspaces making them very heavy in comparison to modern brick).

    Should this be ok?

    Secondly he has used screws not square twist nails on the joist hangers. I understand that screws are more likely to sheer through, but a structural engineer friend has said should be ok for domestic loads. Any differing opinions?

    Thanks in advance for any help.

    It seems that the builder knows what he is doing
