@mattblaze assuming those are 6-foot scaffolding sections the floor right in front of the row of text they're supposed to remove is at 36 feet. That's well within reach for a scissor lift. Even if those letters are heavy, they could bring a cherry-picker in to stabilize and remove the letters as they're removed. They used a similar setup to install the unwanted text.

I can't help but believe the scaffold approach is a way of stalling.
