Everything had navigated past it before hand, there was indeed room to pass. Unfortunatly, as is the case with a lot of buses these days I think the bus was travelling a little too fast, and trying to be a bit over enthusiastic with their manouvre.
Given the damage to the bus I would suggest no effort had been made to slow to a safe passing speed.

I would not say the skip was placed in a dangerous position, rather that the driver was being rather careless. I have seen much smaller gaps left by skips and delivery lorries before.
In an ideal world it would have been further up or down the road, but there are post and a raised kerb preventing that.
