    Can you attach a Conservatory to an Airey house?

    Yes, you could stick a conservatory on; however, it is a little bit involved, as the support structure comprises concrete posts at roughly 1'6" centres, cast around a hollow tube akin to a scaffold pole and used primarily for handling during the casting/curing process. The posts are storey...

    C30 Concrete

    And you are probably exactly the self-same person who whinges and moans that things seem over-designed - which they are, of course, due to inbuilt safety factors that are there to cater for prats like you.

    Calculations for RSJ

    I'm registered with them - but you're outside my catchment area :). Seems alright for a quick visit, measure up and a beam/bearing calculation.

    Calculations for RSJ

    Well he's not a qualified structural engineer [ABE like to masquerade as structural design experts when they are not] and he doesn't mention if he has PII. I'd be surprised if the structural solutions that he provides are the most economical for a given situation: for £50 a pop, not too much...

    Notching joist 200 x 50 by 150 x 65

    Place 50x100 either side of joist x 750 long below notch position and bolt through with 4M10s, should stiffen it up fine and dandy.

    eucalyptus tree and Foundations

    If a tree significantly predates construction and it's in a clay clay soil, then at some point, gradual rehydration of the soil will result in its moisture content becoming greater than that which existed at the time of construction and you can get the opposite of subsidence: heave. This...

    Calculations for RSJ

    Will a chartered engineers calc's be better than a non-chartered engineers calc's then? Regarding the various levels of qualified engineers, there is no reason why they should necessarily be so. There are plenty of incorporated engineers who are as good as, if not better than chartered ones...

    What a the correct fittings for installing a RSJ

    Might be a timber framed building. In which case, there's nada wrong with steel sitting on timber, providing the bearing has been checked out. Tbh, from that photo, you can't tell *what's* going on with any certainty.

    another question about lime

    Hi Rick Well done on getting your degree and good luck with progressing to taking - and passing! - the AM/CM exam at some point (which one will you be doing?). Nive to see that your dissertation covers a more traditional building material. Would be interested in having a flick through, if...

    Bed shakes in new loft conversion when windy

    Point taken, but by looks of the photos, it all is prolly ok, just that whoever designed it never stopped to think of the effect of lateral forces on the structure.

    Bed shakes in new loft conversion when windy

    So? Compliance or otherwise with that piece of ratshit legislation has nothing to do with it wibbling in the wind.

    Bed shakes in new loft conversion when windy

    The original truss roof timbers are very lightweight and slender. They work by triangulation. This has been taken out by removal of all the internal members. The beam is a UB, rather than UC, so has little in the way of lateral rigidity. The wind blows on the roof slope, the load transfers...

    loft conversion

    You've got a kingpost gang-nail trussed roof, with some loose infill for some reason. To be honest, the headroom looks minimal and, by the time you've got additional depth joists, plus rafter insulation, battens etc, you'll have even less. Looks to me like there's very little in the way of...

    A Question of Strength from the Professionals Please

    FMT Noses' plate works as it goes under both leaves, so the outer leaf provides resistance to uplift caused by the inner oversail. Corbelling would be over so far, with the load on it it would want to collapse. Not a nice solution - assuming that it would work in any event. If ir looks wrong -...

    A Question of Strength from the Professionals Please

    It probably would still be ok if all in timber, but would require reverting to the manufacturers for some calculations. Nose's suggestion is the best one viz another block leaf to make it 9", then insulate internally. Of course, you'd then have to think what you were going to do at first...
