Well we already know who we dont want to see build the stations *cough Acciona*.

And to add, we already see how great *sarcasm fully implied* a relationship Metrolinx has had with the joint Aecon and AtkinsRealis (aka SNC-Lavalin) venture with the Crosstown line. So based on my non-technical analysis, that would leave one option in my books.

What did Acciona do?

There's so many places we can start from, the list is endless. The more appropriate question would be, what did they not do:


Herb Gray Parkway (Windsor Essex Parkway):

https://www.infrapppworld.com/news/...-parkway-concessionaire-gets-fined-for-delays


Walterdale Bridge:

Site C Dam:

https://www.theglobeandmail.com/can...-site-c-dam-delayed-costs-jump-to-16-billion/


Broadway Skytrain Extension

https://www.biv.com/news/transporta...rvice-date-disappears-project-reports-8273193


North Shore Wastewater Treatment Plant

https://www.cbc.ca/news/canada/brit...tment-project-suing-metro-vancouver-1.6404421


So essentially, if they choose Acciona they're basically guaranteeing themselves a fiasco.

Let’s hope the folks at metrolinx know more about Acciona than even we do, and act appropriately

I'm sure you can find articles like those listed above for most large contractors.

Acciona is part of the team for the Ontario Line elevated section so Metrolinx has already taken the risk. Plus Acciona is one of the two Yonge North teams (the other being Aecon) that will be awarded shortly.
Aecon has already won the Scarborough stations package so we'll see if they have the capacity (and Metrolinx believes) for that, this one, and Yonge North.

Sure you can, but no where near to the scale and frequency as Acciona.

Yes they have, and Metrolinx will very likely soon discover the repercussions of that decision once Acciona starts their part.

Metrolinx would be very wise to avoid awarding the contract to the team that involves Acciona.
 
There is an argument that ML purposely choose companies that "legally" bribed the PC party and/or hope they would mess up to delay the cash flow.

Slide deck from the 14-May open house has been posted on the ECWE website. This open house was to summarize the work performed by West End Connectors who were the contractors for the main tunnel section. WEC is coming close to completing its project scope.

I've pulled out a few pictures from the slide deck and put them down below:

The concrete has to "cure" for a time before they can build up upon it.

Too bad they don't use "Roman concrete" (made from pozzolanic ash from near Mount Vesuvius. It reacted with lime and sea water to form a compound called calcium aluminate hydrate, contributing to the concrete's self-healing properties), but since Metrolinx is looking to save many, it would be too expensive to use. Metrolinx goes for the cheapest not the best.

??? Metrolinx writes specs, and uses standard specs, which contractors fulfill.

Which agency and contractor is using such concrete currently - or even last century? More importantly, do you have strength/curing time curves for that "concrete"? I thought even the ultimate compressive strength of the "roman concrete" was relatively low - let alone after 28 days.

I read they need salt water to cure it too. Perhaps get a few boat loads shipped from the Mediterranean Sea.
