I also checked MLP14-12L (pile cap type F3A) based on the pile deviation you provided to us and confirm that the actual reinforcement is still adequatd.
There is no need to increase the width of the pile cap (transverse dimension of 3000 mm), as this dimension is controlled by the pier column width and not the pile minimum edge distance.
We just received the pile deviation for MLP14-13R and we appreciated your concern in trying to improve accuracy on site.
I will check this pile cap as soon as possible.
