We ran into similar issues a few months ago on my job. Plans originally called for us to subgrade right up against the bottom of a 16ft rockery. Design subgrade was set below the keyway grade, basically meaning that rockery wouldn't have a keyway locking in the 6-man rocks at the bottom anymore. We ended up getting them to redesign that. On the other side of the job, we were supposed to dig storm and set CBs right along the top of *another* even taller rockery. Maybe not that bad, except that this rockery had multiple layers of geogrid in it, and our storm trench would make us have to dig through at least 2 layers of it. When we pointed that out, the superintendent's suggestion was to just hand-cut the geogrid with a sawzall as we exposed it. We couldn't believe it. 1. That would slow production way, way down. 2. There's still the possibility that the operator snags a tooth in that geogrid and yanks on the entire wall. Even more of a concern since the entire topside of the rockery was recent fill, and we were digging in the rainy season. 3. Even if it went well, after we were done the rockery would no longer have the geogrid it was engineered to have to hold it in place. We ended up going over his head and luckily, the big boss immediately agreed it was an issue and we were able to get the whole storm run moved. I could go on and on about all the issues on this last job, like how there was a sidewalk next to a parking lot with a 12 ft grade drop, and somehow no one before me had noticed there was absolutely nothing in the design to hold up one section of it. I guess the engineer just imagined a 12 ft vertical cut in dirt standing there forever? Hahaha That rock you're digging in looks like a nightmare. I thought the glacial till we had up here in WA was bad (I've run through a set of tiger teeth a day before), but I'm glad we don't have to dig in pure rock much at least. Good on you for calling out safety issues! It happens way too often where no one sees them, or no one wants to say something and rock the boat.

Who ever stacked that wall is very skilled

You're doing the right thing. God forbid someone gets caved in on, there's no going back at that point.

good for you usually it's safety when it suits them
