Metro Rail Tunnel - Building Thread

 
  Tony M. Locomotive Fireman

There was a bit of a push when these plans were announced to alter exactly where the new underpass would connect with Campbell arcade - while the large shop directly to the right of the ticket barriers was derelict and had been modified relatively recently, the smaller shops further along the arcade under Flinders St were pretty much in their original state and had tenants. The proposed entrance would have removed all the shops on the right hand side (including the barber at the corner next to the stairs to Flinders St, who's been there for a number of decades), and put the shops on the left behind the ticket barriers, making them a lot less attractive to the kinds of business they currently have.

Going by those plans linked to above, that hasn't changed - but it does explain why those plans are "subject to a future heritage permit", which I assume has been sorted out one way or another by now.

I believe the space behind the telephone signs was recently (a year or so ago) used for a hipster bar, and my guess is that once construction is complete they'll be looking to put something similar back there.


*edit: no, it seems like the Heritage Permit side of things as far as Campbell Arcade goes is yet to be sorted: https://www.theage.com.au/culture/art-and-design/sticky-has-reopened-its-doors-but-be-careful-with-the-zines-20200611-p551nv.html

Woops. Forgot about the Miki barriers.
Doing exit from Town hall, and then touch-in for Flinders St is not a "seamless" cross over.

The Myki Barriers are moving to where the current staircase is to exit on to Flinders Street, all of the retail that remains will be in a paid area. Might end up with a 7/11 as opposed to the record store that is there now. Im not sure if they have estimated how many people will transfer and walk past those shops.

Metro website updates show that the two TBMs tunneling towards South Yarra have traveled 311 & 211 metres respectively. Unfortunately, they haven't updated their home page to reflect that distance

For those on Farcebook, there is an 'Open House Facebook Live' event this Saturday at 1400.

I can't provide the direct link to the event but the link will get you close enough to be able to find it from there

JOAN is now passed half-way @ 704m. Might enter her in the Melbourne Cup, at this rate will arrive in Parkville at least a month early.

Just can't get over how huge (high!) those main caverns are.

As they move inland from Arden, surely the ground starts to get a bit harder? Second half of the journey might take a little longer.

The caverns are excavated deep, then services are put in and the platforms built over the top. There will also be ceilings put in, so they wont be that deep when it's all done!

Shame! I think they should try and keep the cavernous structure. They should take advantage of the natural artform that engineering can manifest (by showing the structures' bones). If the geology was amenable to it, they should also try and preserve some of the natural geological formations underground too... I'm thinking of the stations on the Citybanan tunnel in Stockholm.

Yipee, the beautiful artform of shotcrete and re-bar.

They did that at QV outside Woolworths.  It just looks unfinished.

Each to their own. I think there is something quite appealing about seeing the internal workings of buildings because the structures themselves are a reflection of the skills and talents of human ingenuity. That in itself is what makes the engineering and architecture of the buildings fascinating.

That was the story about a month ago.

And yet JOAN keeps going faster. Today @816m. Thats over 100m in 5 days, double the expected rate.
Now past Errol St.

Joan isn't alone in travelling well. According to the August Domain update Millie has dug 880m, which is past the half way point of her journey to South Yarra with Alice 200m behind her

And the speed keeps up. https://metrotunnel.vic.gov.au/
JOAN is at 1030m today. That's 214m in 13 days.
At this rate can expect a break through before the end of September.

Not really surprising that all 4 TBM are not having a slow down, despite stage 4.
The nonsense "strike" by the consortium a couple of months ago only resulted in the machines "sinking", obviously a costly scare not to be repeated.

Hey @justarider, when you say 'sinking' what do you mean?

Was it really last December that the consortium stopped work ?

Report at the time was that the stationary 1000T machine had started to settle into the ground. It was an incentive to put the dispute aside and get moving again. Cant find it now. Probably the HUN.

Another update of the TBM's has Joan within 200m of the Parkville station box, 1.22km traveled of 1.4km to be precise, and Meg at 858m, more than two-thirds of the way.
Alice has traveled 1km from ANZAC with Millie having covered 866m of the 1.7km to the eastern portal.

As per the Metro Tunnel Instagram Page TBM Joan has reached Parkville.

1.4km over 68 days (my count, couldn't find an official one) is 20.6m per day

@tayser do you have any info on whether this puts Joan ahead/behind schedule?

early October for both TBM to have arrived.
Meg looks like another month to go, so maybe a couple of weeks early.
