RSJ replacement. Am I being difficult or is it the builder?

[Jaygray]

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.
