Hi
I've submitted some drawing to the building control for various works. They have now come back and asked for engineers calculations for structural beams and lintols.
I don't have any structural beams going in (I'm not having any walls taken out).
I am having a doorway created through the hallway wall. Also I am having a window opening made wider. Do I need engineers calculations for new concrete lintols for window openings?
Many thanks
