You would not believe the work involved in installing an automatic bollard.
When you walk through your town pedestrian shopping area, you see some automatic bollards in a line, to control vehicle traffic.
But peel back the layers of the bollard installation and see the amount of work involved.
Pits, concrete tubes, sand, drainage, cables and then a final surface finish of tarmac or concrete.
Spare a thought for engineers who prepped the ground in readiness for your bollards.
