Well, except the Allen ... which slows to a crawl before Eglinton.

One of the videos that they have posted on the site says that the TBD on average moves about 10m a day. Based on where the October 1st update was the TBM should be at Marlee right now...

I'm speculating that the contractor had unused float in the schedule (a good thing - meaning they finished the segment well before the drop dead date) and they aren't advancing so they don't have the TBM coming out into daylight before they are ready for it. Or maybe they have a photo op date in mind for the breakthrough (after the election?) and aren't playing any cards. The second TBM appears to have stopped moving also. Wonder if it will be a single or double breakthrough.

My recollection of the first tunnel drives on the TYSSE is that they waited to break through the station box wall for at least a week, if not a few, for a photo op of the TBM punching through that concrete.

I guess delaying a project for TBM breakthrough after the election is a good way to show that there is no politics in Toronto transit.

Last i passed by the site, excavation for the extraction shaft west of the allen was not yet complete. until that's done nothing else can move. if it is the case that the TBMs have moved ahead of schedule and thus got their before the scheduled shaft completions then I suspect we wont see much movement at all until we get some solid shaft completion.
If it is the case that the Shaft construction is delayed for reasons beyond logic and thus holding up the TBMs then i think someone working on project schedule management needs their head checked. im emailing metrolinx about this and will post their response.

How do you all know that the TBMs have stopped? It's not the site has a live GPS location of it lol. The person could simply not be updating the thing, as it hasn't been since Oct 1. Previous to that, it was several weeks to a month between updates as well.
Anyways, Metrolinx said at their board meeting it's likely finishing around the end of year.

Eastbound traffic on Eglinton was backed up from Bayview all the way to Brentcliffe yesterday during the evening rush. There are 3 sections on this stretch that narrows 3 lanes down to 1. It's faster for me to get off the bus at Bayview and walk home to Laird. Just brutal!

I do hope you get a good answer from Metrolinx, but I'm not optimistic. As I understand it, the contracting strategy that Metrolinx is using gives the contractors a lot of latitiude to set and adjust their own schedule so long as overall targets are met. So any one 'bump' in the schedule may not even be disclosable to Metrolinx. (In fairness, all may be well, we sidewalk superintendent junkies just aren't in the loop!)
A big issue for me is the lack of transparency and public oversight (I mean oversight by the average citizen, not some political panel that is sworn to secrecy) on project management of these big projects, transit or otherwise. It's not constructive for everyone in the city- or the media - to make a big issue about some minor schedule slippage, but it's also not good if some major issue arises and months go by with the issue (and potential accountabilities for cost or schedule or quality) swept under the carpet. We saw that with the Spadina line when work halted for months due to unforeseens with foundations of York University buildings, and we saw it with the Niagara Tunnel project when Big Becky hit unexpected rock conditions. In both cases the progress maps simply showed the tunnelling not advancing, and no comment was made for quite a long time. In my view (as a taxpayer) that's not acceptable.
If I ran the world, some level of the project Gantt chart would be publicly accessible, with cost information (at least on a red/green basis), and major changes to the schedule documented over the project lifetime. I'm sure the GO Executive and Board would say that it's their job to oversee this stuff on our behalf, but they simply have too many publicity staff and too much latitude to answer to politicians 'in camera' to trust the governance.

Folks, underground transit construction never disrupts on street life. Subways Subways Subways. Stop the gravy train

This is just because the liberal City Council hijacked the ECLRT project and is now using at a proxy for their War On Car.

TBM Tracker was updated about an hour ago. Dennis is about 250m (at Marlee) from the extraction shaft. Lea is trailing by about 350m (at Oakwood now)
