Where is that in relation to the fence?

Hi. I’m a local journalist who visited the site while it was under construction. The toppers are, indeed, precast concrete with rebar on the bottom. The photo may show that, but it’s hard to tell. https://www.midvalleytowncrier.com/2020/01/22/challenges-remain-private-border-barrier/ …pic.twitter.com/jeW5lVGSZe
So the bollards are not filled with concrete to which the rebar would be attached? They're just set there, with a metal cap and free to fly away?

From what Fisher told me, they are filled with pea gravel. Then concrete is poured in the top few inches & the concrete toppers are set atop the bollards, with the rebar sticking out of the base anchoring into the concrete that was poured in. 1/2

The reason for the pea gravel, he said, is so that if someone tries to cut a bollard, the gravel will flow down at the point of the cut & prohibit the bollards from being removed. The tops are meant to be removable in that instance to refill the bollard with more gravel. 2/2
