Perhaps this is usual, but when Caltrain was building the new approaches for the elevated Hillsdale station I noticed they were just pouring concrete on top of plants.
Maybe not the biggest deal, but I’m pretty sure the engineering algorithms assume a solid mass of concrete. Hopefully there’s enough safety margin that this doesn’t matter.
- LegitShady 5y agovery unusual
- SECProto 5y agoNot usual - what sort of plants? What did the concrete look like it was doing? Organic material would be fine if it was underneath eg, a temporary pathway or something, but that's about it. Actually it might also be fine for secant pile cap (talked about in this video[1]): when you drill a secant pile, you generally pour a concrete cap (that then gets drilled away).

- jdavis703 5y agoI would describe these plants as large, probably seasonal weeds. So it’s not like they were woody trees or anything. Just seemed kind of shoddy.
