Main issues:
lack of vertical and horizontal alignment – the elevations were "tilted",
lack of proper geometric reference (drawing without relying on the plan and section),
scale inconsistency – the elevations did not correspond to the dimensions resulting from the documentation,
drawings made by reproducing the graphic background, instead of technical development.
As a result, the submitted documentation was not suitable for further design use and required to be redone.
On the positive side – good communication and quick response to reported comments.
