People talking about the concrete saws don't know anything about them. That diamond blade would be toast in just a minute from overheating. Bollards are core filled and by the looks of it a 16" blade can't cut the whole way through.
If that's concrete in there it looks like its glass fiber or Kevlar reinforced 3/8" box steel. You are not cutting that with a diamond blade, you need an aluminum oxide wheel. The core filling will fuck up the aluminum oxide wheel, even in its just core filled with sand.
t. concretefag, builds big walls and parking garages.
I covered this yesterday

You guys ever do this kind of work? Both of you are way off the mark. Pinching a concrete saw isn't going to do much, they have a ton of horsepower behind them.
Kevlar or even glass fiber reinforcement will dull the blades in a hurry. 3/8" box steel will fuck up a diamond blade in a hurry and concrete with explode an aluminum oxide disk.
It looks really solid, albeit not impervious. I'm not sure any of those can cut the whole way through meaning you'd have to use a sawzall and be there forever to make a meaningful hole.
Also, USMC Sensor Platoons have been working the border. Layered defenses.
It's all good, was a friendly reminder. A lot of shit gets thrown around here and doesn't always stick the first time.
Some morning moto for you faggits
It's possible, I was thinking that for a bit yesterday. But looking closer I think that isn't the case, all the vibration would have knocked a lot more of the sand out of the top of the bollards.
Possible but still dangerous. Concrete can explode when exposed to extreme heat.

One of the CBP contract requests calls for a solid concrete wall, while the other asks for proposals for a see-through structure. Both require the wall to sink at least six feet into the ground and include 25- and 50-foot automated gates for pedestrians and vehicles. The proposed wall must also be built in a such a way that it would take at least an hour to cut through it with a "sledgehammer, car jack, pick axe, chisel, battery operated impact tools, battery operated cutting tools, Oxyacetylene torch or other similar hand-held tools."
You make it sound much quicker and more simple than it actually is. I work with concrete every day for a living and have two associates in welding and machining, although I have no practical machining experience I do frequently weld on the job site. We do walls and concrete for large commercial project including renovation and construction of parking garages.
For one, a torch or saw will be a mother fucker to carry through the more remote locations that are inspected less frequently. Second, you WILL need PPE if using a concrete saw or torch as no matter which method you use to breech will result in something exploding, whether it be your diamond wheel, aluminum oxide cutting disc, or the concrete being subject to extreme heat exposure.
Grinding concrete is a really time consuming ordeal and would be even more so if the concrete is Kevlar reinforced as I suspect it is.
No matter which way you cut it, getting through will be time consuming. This is why the Marine Corps Sensor Platoons will be important.
Remember, this is just another layer of security, not the be-all end-all security solution.
