Wanted to check if the method on the drawing attached is ok. It's for a wall going across the back of a side extension flush with the back of the existing but doesn't feel completely right as it's not in the middle of the padstone.
Placing steels off-centre on a padstone

- Start date
He only specified the beams and padstones as 440 size. He doesn't seem to give a lot of detail on anything. He knows it's flush across though

Yes full plans but the the engineer is a piece of work.
If I have to I'll move the wall in, 8 inches seems the norm I suppose?
Step2 then, ask BC if they are happy.
All the padstone needs to do is to distribute the beam reaction into the masonry under so the latter isn't overstressed (think snowshoe). The bigger the load or the weaker the masonry, the bigger the padstone has to be. If BC remotely concerned about eccentric loading as you show the go to the L shape
Don't move the wall: there are bound to be knock on effects

I agree about moving the wall. Think the steel being on the very edge is a bit weird though I can only think of throwing mortar in there.
If it's the specified padstone, then the only potential issue may be bearing shear. In which case a centering plate could deal with this.
Strictly such a plate should be designed, but normally a 10mm plate is adequate for domestic loading.

I'm guessing that's a piece welded to the beam and not a mold?
It's a flat piece of steel that is placed beneath the beam.
As per Mr 888, an L-shaped padstone would have solved the problem, even if one arm needed to be cut down a little.
Yes I've been looking at prices for them. Was wondering if the beam should or shouldn't have a longer bearing on the pad?
That's another issue. It would have to be a very high load from the beam for the 100mm leaf width to be insufficient. (FWIW that's where you might need a steel spreader)
