Get a piece of electrical conduit or similar.

Bend it to whatever curve you need to deflect the pole to the correct path.

As far as seeing, you can tape a phone to the end of a broomstick to get it 5-6 ft under the platform and just FaceTime to a second phone so you can see what the first one is doing.

It also looks to like if you could flexibly long a couple of broomsticks together you could use the vertical supports to deflect angle the sticks towards the direction you want.

Not the most elegant solution, but something you might be able to put together with some supplies from the building staff and a roll of duct tape.

Cheers,
Gabe
