Pipe pile aren't driven to bedrock or at least they don't have to be since they're held by friction. They are just driven to refusal. Basically you drive them down and when you think they're good and they hit minimum depth for the size of the pile a technician comes out and does a blow count then does some math and figures how much they should support. It's possible to hit a rock layer break it up, get refusal and then have it fail. It's also possible someone did some math wrong.

I bet someone looked at the minimum pile depth to avoid scour failure and was like "Yeah we've reached 20 feet, we're done" and failed to get the actual support amount. It doesn't help that that spot out in the middle of the stream would have been awkward to reach for 'normal' equipment.

Yeah, forklift fork extensions are a thing, but they are for handling bulky loads that are up to 50% larger in size than normal, not for dangling containers of metal scrap way the gently caress out there...

When I lived in Saskatoon, I discovered the wonderful thing that is the set of small, free, river-crossing ferries across Saskatchewan. I unironically love them. The vast majority of other people who use them are farmers who live nearby and the ferry is the shortest route from one side of the river to the other; often the nearest bridge is a few dozen kilometres up or downstream. The ferry crossings become ice roads in winter, which just adds to the appeal to me. Dyck should get a boat as a memorial in Hyas, not a shittastic bridge. Flash Gordon Ramsay posted:Shouldn't the supports go down to bedrock? Does bedrock fail/settle? Most of southern Saskatchewan is sitting on glacial till ("poorly sorted" mixture of rocks ranging from sand up to multi-tonne boulders, covered by soil) or pro-glacial lake bed, which is fine clay and silt, on top of glacial till. Consolidated bedrock is sometimes a few kilometres down. But, your point is quite valid - it looks like the bridge supports were just sitting on the fine silt-and-clay, water-saturated river bed, which has the consistency of rotting fruit and smells worse. Even the layer of probably-clay that's under that is probably strong enough to hold the weight of a little bridge like that (even with the comically-overloaded grain trucks that Sask farmers are so fond of running), and I guess it could settle or the other materials (lots of big rocks, I think) that they probably put down around the hole might have shifted. I am not an engineer, I'm just a soil scientist with a fondness for prairie rivers and ways to get around on, over, and through them.

She's so utterly desensitized to error messages popping up that what they're saying doesn't even register. The whole thing reads like she has no real understanding of how the machine actually operates, she just knows what to do to force it to work. She's got that "get it done no matter what" attitude that when coupled with failing technology causes the most spectacular and horrible kind of failures. She was clearly negligent, but it sounds like it was only a matter of time before that machine malfunctioned as it did for someone.

The real issue of that CT affair is hospitals never upgrading or doing preventative/proactive maintenance. The unit was probably old as poo poo, and never got upgrades or modernization. This is how all hospitals work, they grind equipment to dust until it breaks and there no parts left on the planet to fix it or all the service engineers that learned the arcane mysticism to repair them are dead (this isn't even a joke). Unless you're at a research university hospital, the imaging equipment is most certainly 10-20 years old. Anything new is most likely just 5 year old refurbished poo poo. All the stuff I work on is at least 15 years old. I've had to learn by trial and error various workarounds to various procedures that no longer function. Management doesn't care, corporate doesn't care. It's not getting fixed and it's not getting new parts, just work around it. There is very little that forces companies to upgrade their imaging units in a timely manner. There is some weak poo poo like XR-29 and CMS cuts to reimbursement for non digital radiography. It's a start, but mostly it just means some accountant works more numbers to see how much longer they can go with the reimbursement cuts before they finally need to upgrade to maintain profit margins. As technologists, we're taught how to operate the units, but that's it. It'd be impractical to expect all your techs to have a biomedical engineering degree when you just need someone that can push a button. Companies don't waste money making their proprietary software user friendly when it starts barfing up errors. When the unit fails or does something unexpected you restart it and if that doesn't work you call service. Hope you have a service contract/the manufacturer didn't go out of business 10 years ago. The error codes will usually just be a code without any useful description of what is wrong, as it is expected a service engineer is going to look it up in their secret proprietary error code tables. The 'keyboard turned off' on our 1994 unix workstation according to my computer illiterate coworker. Very much considering just calling out tomorrow because I do not want to deal with this loving bullshit company that is too busy giving themselves promotions instead of throwing this 20 year old camera in the dumpster.

It's possible to hit a rock layer break it up, get refusal and then have it fail. It's also possible someone did some math wrong. It could also be dilatant sediment. On a major bridge nearby, the piles were driven to refusal, but after a few hours they began to sink again. By the time they'd stopped sinking, the tops were much lower than they were supposed to be, and extensions had to be spliced on top. That could have happened in the Canadian case as well. Basically, the sediment acted as a non-Newtonian fluid, and the faster the shear was applied, the firmer it got. I believe in this case the root cause was saturated soils with low permeability.
