Could you not get the engineer to redo calcs without using C16? They
seem to quite often specify timber grades even when they aren't actually
necessary.

Yes this is the way to go I think. I had some oak soleplate replaced
this summer with new air dried local oak and the building inspector
wasn't at all interested in numbers like C16

Mind you my supplier charges more than 5.50 a square meter for oak
flooring. Drool
