I have to join an existing footing with a new reinforced cage. A enginner gave me drawings to follow, but i cannot get hold of the engineer to explain me some parts of the drawing.
I have uploaded an image of the drawing.
What I am confused about the part: New concrete to be dowelled to existing with 2no H12 dowels resin anchored at 300mm centre. ( i do not understand the 300mm centred, what do they mean by that, as the cage is 450mm height.)
Do i just centred (resin anchors) it from the centre of the cage 300mm apart?
