Figure 10_Stack 2 builder’s sketches of the position of earlier RSJ’s inserted during remodelling works which removed the wall below. Note: the stacks flue cranks therefore the tie down post tensioned detail was unable to directly tie the stack down to the RSJ’s. With engineer’s approval the stack was stiffened at the roof plane and additional helifix ties link the reinforced stack back to the masonry supported on RSJ’s.
