There could be a reason underpinning was delayed - cash flow. In 2011 the financial crisis was still receding.

I mean, to be clear they one bad thing they did with the line was package everything as a single contract. Early works included. Even utilities which werent even touched until contracts were signed leading to lawsuits.If everything went smoothly is a very naive way of project management.
Metrolinx started TBM tunnelling in 2011. TBM tunnelling is historically the most straightforward part of the build process. Why was that prioritized over commencement of construction of more critical and risky portions of the line such as the underpinning of the 2 interchange stations with Line 1. You're right, Kennedy should've started at the same time to limit the impact of any unforseen issues.
As @Northern Light mentioned, delays need to be accounted for and baked into the schedule.
When you spend literal tens of billions of dollars, completion dates or milestone dates are critically required.
To be fair, Ontario Line is prioritizing better. Having started station construction already and working on critical infrastructure. They've also negated having any issues on underpinning by not performing underpinning at all in the Downton interchange stations! Lol
Crosslinx’s notice didn’t include a detailed claim, but it alleged that work by utility companies had exceeded time frames guaranteed by Metrolinx and interfered with the construction process.
It also cited “issues regarding permits, licences and approvals” and “delays” and “disruptions” affecting the design approval process.
If I remember (and it was discussed in the thread at the time), Metrolinx was going to have city/TTC do the work at Eglinton and Eglinton West, and wasn't part of the original contracts.There could be a reason underpinning was delayed - cash flow. In 2011 the financial crisis was still receding.
It wasn't a single contract. TTC had set up to do multiple contracts, with two tunnelling contracts, and multiple station contracts. And separate contracts for the tracks and electrical, etc. TTC had already awarded and started construction on the tunnelling west of Yonge when Metrolinx transferred the work to IO in 2012. And Metrolinx ended awarding the other tunnelling contract as well, rather than roll it into the design-build.I mean, to be clear they one bad thing they did with the line was package everything as a single contract.
