RSJ install gone wrong?

    Hey guys...

    I am not a builder but do have some common sense. Is this RSJ installation completely unacceptable? I think so but need some confirmation. It appears to be resting on a thin angled piece of mortar that was either left on the the brick or chipped off and placed underneath. Same on the adjacent RSJ too but at least the other one is flat. This is for the external loadbearing wall of two storey detached house.

    Yes it's not right at all, there should be some form of pad stone set in for it to sit on and the steel should overhang on to the pad stone by a minimum 150mm preferably 200mm.

    No, its not been done correctly, especially as its the inner wall too and carrying more load.
    Easily rectified, but good job you spotted it.

    Quite apart from what you hear from this forum, your building control officer would not and should not accept that.
    Has anything been built on top of the RSJ yet?

    It looks like it has been there for a while. Its just a matter of propping it up and constructing a better base for it to sit on.

    No point in contacting Building control as they won't be interested after the work has been signed off.

    Nope... believe it or not this is a new installation of the RSJ's. Spanning the width of the living room with upstairs and roof ontop of these. Common sense tells me that weight should be spread evenly across the brick pillar and not balanced on a 2p size of mortar rubble ridge.

    This is the view from the other side of the plasterboard.

    presumably building control is involved - they should be. Get them to come in and have a look and then watch them explain things to your builder - followed by you saying you will not pay

    As above.. The building inspector should definitely have something to say about that.
    Definitely needs a padstone for it to sit on ..

    If a building inspector has given permission to proceed or failed to come out when requested and the builder has carried on, they won't revisit the work.

    The problem you have as well now, is if the work you can see is poor there is potentially problems with the column either side and the footings

    DO NOT PAY A PENNY UNTIL THIS IS RECTIFIED! It's a hazard, and even more so if wall has already been built on top of it.

    could it be resting on the pier inside the room and the bit shown in the photo is just an overhang, as in the raj was a bit long.

    Looking at exhibits, A, B, and C. It's obvious the rsj is passing over another wall. You'd be luck if them bits of mortar could support the beam alone, never mind any applied load.
    Then we finally received exhibit, D.
    Now't wrong and all appears good.
    Yet still folk want to see the builder in the stocks.:rolleyes:

    RSJs and they are at different heights.

    A bit more dot and dab applied to one side of the covering pb and jobs a good-un.
    As can be seen with exhibit 'D'.
    Looks kosher to me.

    The RSJ is passing next to the other wall not over it. Originally there was the back wall to the house prior to to the extension that you see. The RSJ now replaces the original back wall to the house allowing a larger area into the extension. The mortar the RSJ is balancing on is 50yr old from the original wall. Builders have now returned and said its fine as its packed above with slate so the triangle effect wont allow for any movement. What about the fact the mortar may give way under stress over a period of time??

    Take a hammer and chisel to that '50 year old mortar', remove it, scrape it out and see what happens.


    It's not supporting the RSJ's. (IIR, noted ;)).
    LABC have signed it off I take it?

    UPDATE - Thank you to all that have commented positively about the poor workmanship. However things get even worse!! Please view the video I've posted which shows what the RSJ should be supporting and isn't actually supporting! There is a massive gap between the RSJ and upper back wall of the house. 3 blocks of wood, 2 of which can be moved are wedged underneath instead of slate.
