How did they level/plumb these street light poles and keep them floated during pour?

You mean like use a host site for the image like we used to do?

Must been something wrong at time you tried? I just posted an image by copy/paste like I normally do since this site started with the current forum software.

Or maybe your image was too large or an unsupported file type?
 
I worked for a company once where they subcontracted out to a company to put them up for us. It is a lot of work and you need special equipment, and preferably several bodies. The bases were already done. They apparently were not required to make them plumb because they looked awful when they were done and gone. I made up a piece of wood that I could center on the top with a hole in the center. I dropped a plum bob down inside the pole the entire length to the handhole opening. I measured through the handhole and adjusted with the leveling nuts. The pole protected the plumb bob from the wind and I was able to adjust them all by myself with a bucket truck. It was a pain, but it was done.
 
Many, many years ago, a friend of my father was an engineer for Otis Elevator. Otis has their elevators in the UN building in NYC. There was some question about whether the shaft for one was plumb for some reason. He went to the top of the building with a long string and a weight. I assume he brought the top of the car up to the machine room so he could work off it. He rigged supports so that he could tie the string, probably via a pulley in the center of the shaft. He brought the car down then dropped the weight to the bottom. It was pretty close.
