I've had the builders in replacing a wooden lintle and archway on my external wall (now had an extension).

The builder put up acros but didn't use strong boys or needles. Once he removed the lintle, the arch and 4 leafs above predictably gave way and feel down.

This meant we have to ad a 300mm by 10mm plate to rebuild the brickwork and support the wall plate for the flat roof.

This meant he couldn't properly relay the brickwork above the lintle and as such the t
Hree courses are all different hiigjtt with morta joints 70mm - 30mm in places.

Obviously the lack of strongbiys ways stupid. But am I over thinking the large morta beds?

When joists are built in, it is normal to prop them to support the wall above, not use needles or strong boys.

The wall above should not drop, if it has then the builder did not check it and wedge it properly.

I don't understand the bit about needing a plate.

Joints would normally be packed with brick, tile and slate, not just thick mortar.

It looks to me like the joists coming from one direction were not built in. Rather they were face fixed to a ledger plate.
 
Only a bit of it has the ledger plate. Which was put in for a through floor lift osme years ago.

He proped the internal rafters which supported the internal leaf. But the arch was left unsupported and as such collapsed immediately.

The attached might help you understand what I mean.

The plate had to be added as the bricks that collapsed were the ones supporting my flat roof wall plate. The 203 x 203 now didn't span the distance to support the bricks he was building back up. So he says.

Agreed with you re slate. He won't do it. Is this going to cause structural problems? Will Building control pick up on something like that? No slate was used.

The other bit that looks like a ledger board is actually a 2x4 they added to build the bricks up above. They wanted to leave that in place with the steel sitting under it. I said no, so they removed it.
