I have no idea what this could be.
These four photos were taken yesterday over a 25-minute period. I couldn't tell from my vantage point whether the red thing was on a roof or on the ground between two buildings. One minute, it held two very long.........pipes? The next minute, there was only one. A few minutes later there were none and a bit later there was one again.
Today, I saw three and then there was nothing - red thing gone, job done.
What kind of work could this be related to?
