Yep, my point exactly. Maybe the city should make a long-shot case to get construction on the line 2 extension sped up (with provincial funding of course). No way that just 3 stations along 8 km need to take this long to be built.
I agree it could take far less time to build, however I doubt that its even possible to speed it up at this point. Part of the problem is Metrolinx' 2 stage approach to subway building, where we first tender out the contract for the tunneling, and only after the tunneling is almost done do we start building the stations themselves. Every subway project in effect is 2 completely separate projects that are done mostly independently. Now I'm not a project manager, so I'm not going to make an uninformed take about whether or not this method of constructing subways is better, worse, safer, or a waste of time and money, but I think its safe to look at other cities like Sydney or Moscow where both are done at the same time to highlight that a more parallel construction approach would likely speed up construction time. What matters is whether or not Metrolinx believes that the faster timelines are worth it in exchange for whatever risks they feel they're undertaking by parallelizing the work (which considering how Metrolinx seems to be very averse to risk and delays, seems likely to be the driving force behind their decision making).
I think that’s just when they were putting it in but idk
Are they building 1 or 2 tunnels for this project?
1 large single bore.
Looks like a normal single track tunnel because there's no track floor yet to give the sense of scale.
aaaaand thats why infrastructure projects in toronto take so long and cost so much. no sense of urgency/incompetency
There would be an inventory of tunnel liners no matter what - they are not shipped just-in-time, but rather as they are made. They are stored on site as there can be peaks and troughs in the production flow, and the last thing anyone wants is to hold up the TBM because there isn't enough liners to fit.
Right, but assuming they've only dug 100m so far, the average comes to about 40cm per day, quite far from "15m/day". Surely something's up.
It's tough to judge, but the distance in the photos attached above looks to be far more than 100m to me. The machine itself is longer than that distance, and so even if it's only doubled its own length, that means they've tunneled more than a quarter kilometer thus far.
