I didnt say they weren't a separate piece. The chunk of concrete with a piece of mild steel rebar sticking out of it is larger than the dimensions of a bollard and not the shape of the top of a bollard. But keep stanning for Tommy.

Extreme close up on that rebar shows absolutely Zero concrete residue. This appears to be a discarded piece that was never installed. Overlooked construction debris that was unearthed by the heavy rains.

A discarded piece that was never installed?Who do you think you're shitting?A piece of concrete with rebar sticking out,broken edges can't be a discarded piece that was ever installed.Concrete & rebar don't come together then get installed. Here's where they met at Tommy's wallpic.twitter.com/3Ppj9GNCYz

But it’s not from the base. If it is, should be easy to get a photo of the damaged section. If it is a topper that came out, should be easy to get a photo of a Bollard missing the cap.

Can't conclude it's not from the base.We can't see the entire piece,don't know how much of it's buried.Can't conclude it's a bollard topper because a bollard topper is missing somewhere.First prove bollard toppers were precast around a piece of rebar then stuck in the top. No way

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

I don't think that makes sense.If you cut into the bollard & learned it was full of gravel,you'd notch the side & let the gravel flow out on the ground.Then you'd cut out a section when it was empty.I'd have to see they filled the bollards after they were stood up to believe it.

Yeah, it does not appear as though any of this was really well thought out or tested. LOLOL Maybe that's why their prototypes were rejected by the government in the first place?

There's a reason the Army Corps-accepted bollard design has a top plate & intermediate bracing tying together the bollards.
