The wall plate on the south face of our build runs across two sections: Durisol and steel. I'm almost clear about how to fix it to the Durisol. But how do we fix it to the top of the RSJ ? Is a simple bit of M14 threaded bar with bolts top and bottom sensible? (Countersunk bolt and bar at the top). Or is this a question the SE needs to answer?

I'm about to pour the last bit of concrete before putting in the wall-plate on the piggery. Have a look at this; Once I have poured the last 100mm or so of concrete, (in the holes you see) I will need to fasten the wall-plate to it. Should I run the wall-plate right the way through the gable, or cut the wall-plate flush with the gable and fill that with concrete? The image below should help explain.. I have deliberately not poured concrete into the gable block in line with the wall-plate - just in case your advice is that the wall-plate should run all the way through the gable Maybe it doesn't matter, and both options are reasonable. Just for information, this building isn't subject to Building Regs: it replaces the old piggery which has stood there for about a century or so.

As I suspected, this learning curve really is pretty steep. So in an attempt to make sure that I reduce the number of errors in establishing our first floor at the correct level, I thought it might be an idea to start a thread - hopefully I'll be able to summarise it as a check list later. First: the end in mind Accurately mark out the position of the top of the wall plate (rim joist) such that our 202 POSIs sit at the correct height. Follow this bit of maths through with me please: Assuming the top of the POSIs is the same level as the top of the wall plate , it (the rim joist) needs to be 20mm (the depth of the decking) below FFH; (2350+255); that is (2605-20) = 2585mm above FFL In order to mark it out, since our floor is currently 25mm below FFL (currently we are at sub-floor) we need to add another 25mm = 2610mm above our current floor Naturally, it isn't that simple is it? Our timber spec is C24, treated, 200 by 50. Well wadya know? Timber of that spec isn't. It's less than 200 and less than 50 (195 by 45 ish). Which means the bottom of our POSIs are going to be hanging low (to coin a phrase). Our hanger spec is 200 by 50 Does it matter that the bottom of the hangers are going to be below the bottom of the wall plate?
