Can they not start building stations once the TBM hits the Allen and remerges up and then goes back down the shaft on the other side? But I guess if its due to money it needs to wait till all the tunnelling work is done. It just seems so long doing it that way.

No, they couldn't start building tomorrow if they wanted to because the stations haven't been fully designed yet.

As I understand it, the way the process works is that Metrolinx has handed over the station designs at a rough sketch level to the two competing private consortiums that are bidding for the project. Each team will separately have their engineers/architects draft the designs up to a much more detailed level, and that in turn will inform the price they'll bid.

They do, however, construct the station headwalls first. The TBM's bore through those concrete headwalls. See this link.

Why is the second TBM so far back? It seems to be going really slow. Is that so it maintains a certain amount of distance from the 1st?

The TBMs need to run a certain amount of distance apart from each other - something like 2 to 3 weeks apart at least - in built-up areas in case of subsidence.

The headwalls only dictate where the station will be built, not in what form.

First TBM is making progress. Quite exciting.

Why is the future launch shaft #3 west of Brentcliffe on the TBM map?

Shouldn't it be east of it?

That will be updated.

But why was it not shown on the correct side in the first place?

For those who live on Eglinton West where construction is currently happening:
How is it there? Do you feel noise or vibrations from your homes? I'm assuming there isn't construction at night right?

TBM tracker updated today. First TBM at Gabian way (about 500 meters from Caledonia Rd), second TBM finally crossed Keele st.

Extraction/launch sites 2 and 3 have also been added to the TBM tracker.

It's like the end of the movie "The Social Network" where Zuckerberg hits "refresh" over and over again.

This is a rather boring movie. Pun pun pun.. ehhh (excuse my bad comedy)

LOL. Try Congee Star near on Don Mills just north of Eglinton. Probably best to go before Eglinton & Leslie is half shut down due to TBM launch shaft construction, if that hasn't happened already .

Posting from other thread... On that note, it still hasn't as far as I know. I last drove by there on the weekend.

Still kinda peeved that there will be no south-side alignment for that section of the Crosstown. I'm not buying the arguments that a new bridge would be needed, there is so much space there. All that we would lose is a few trees.

Beat me to it. Love going to that site on a regular basis.
