And what is the City supposed to do in this situation? City staff are not involved in design and construction, how can they take responsibility? Would you like them to somehow void the p3 agreement and take over the project?

People wanted P3 because "the government can't be trusted, and isn't efficient". Well the consequences of that line of thinking is a project that the City has no real control over.
if you have a p3, two of the p’s stand for public and partnership. in addition, the city controlled the purse strings in spending $1.8 billion dollars on behalf of three levels of government.

is the city completely responsible for this situation (or the host of others in addition to this one)? no, they’re not.

is the city without any responsibility for this situation (or the host of others in addition to this one)? no, they’re not.

that’s the reality of a partnership.

I'll be honest, I never really dug into the agreement itself much so I'm unfamiliar with the details. Other than money, what responsibilities are in the City's jurisdiction? The put stipulations for delays/overruns into the agreement, but is there actually anything else that can be done at this stage?

at this stage, probably not. except to learn.

and between this and the walterdale bridge and blatchford and the library and the police station and jasper avenue and the metro line and station pointe and capilano bridge and dawson bridge and capital boulevard et al, there’s lots to learn…

I wonder why we have trouble now-a-days executing very large projects. Is it something to do with our cultural reality? Something to do with so much social media, short attention spans, few people stay at a job for longer than 5 years, lack of in-depth expertise, that just leads to lower quality work being done?

Well based off of TransEd's record with concrete work, I'm not surprised this is happening. I've seen so many pieces of concrete have to be replaced it's ridiculous. Over the past few weeks alone I've seen so many simple bits of concrete such as curbs and sidewalks being broken up and replaced. Fool me once, shame on you, fool me twice shame on me, fool me dozens and dozens of time, what the fu..!!!
All their excuses are just that, excuses for continual substandard work.

Not official word from Transed, but a qualified person giving an idea of challenges and timelines.
Structural Issues on Edmonton's LRT Line Could Add 6 Months to Timeline: Engineer
I wonder what Marigold is doing to respond to this. They've already formed 1 column in the same shape as these Transed columns; depending on how much they reviewed the design before using it, the Marigold column may be prone to the same issues.

I'm far from an expert on this, but I would suspect the issue is less in the shape of the piers, but in the quality of the concrete work & materials. A "Y" shaped pillar is pretty standard practice. Hopefully Marigold is working to different specs, or at least checking in with TransEd as to what went wrong.

At this point, in future lines the engineers just need to copy whatever design they used in Vancouver for the raised skytrain sections. I don't recall any of the newer lines running into these types of issues, and with the seizmic issues need to account for a lot more. It should be easier and cheaper to build the same system here, even accounting for slow load and the freeze/ thaw conditions.
