It's a commercial, so no problem with the time.
Only thing is, the road is a rat run when the pubs shut so I am thinking 3 or 4am over two mornings for the highest stuff. The back is quiet.
The tower section has ledges that are designed to be walked on and a safety line installed. We are supposed to climb out and walk around. It's a long way down

I will contact the council and see what they say. Only thing is, there is a fee payable to put anything on a road side in aberdeen. A skip, a cherry picker etc.
