While they were thinking about it, one of the construction workers got a pretty interesting idea on how to save the dog.  

They could use the crane from one of their construction vehicles. Basically, the way it would work is that they would get one of them inside a large bucket and get it close to the dog.

Then, that person would try to carefully grab the dog and place him inside, so he could be transported out of harm's way.

A Very Successful Rescue
