At the risk of stating the obvious, the drone shouldn't be flying anywhere near the crane. It's an active construction zone with a structure that moves and swings about in unpredictable ways with people and equipment moving about below. It shouldn't be delivering to the construction zone, and if it can't figure out how to stay out of the area, it doesn't belong in the sky.
There are some FAA requirements about cranes/temporary structures that would give pilots an appropriate NOTAM, but I don't know if all cranes require this. That said, I'd argue that if it isn't tall enough to require notifying the FAA, the drone is flying too low.
