Is it really that much in the long term. What it might do is put a pinch on future projects.

Completely agree it is not a lot over the life benefit of the project but it is a LOT of money to ruin over on a project 20%?

speaking of ruin.

The overspend identified by the Auditor General is $150mill, and that was for advance works to be clawed back (hopefully) later on.
All the talk about escalating that by a factor of 20 is selective leaks to the HUN/OZ.

Seen through the prism of contractors trying to squeeze a better deal through unanswerable public pressure, you can believe what you choose.
It's the modern world of non facts, and blind belief is all that matters.
We will all learn when the State Budget is delivered.

And for those playing along, TBM Joan re-launched on the weekend towards Parkville (Meg to follow at the end of June) and Alice launched towards South Yarra so both tunnels towards the eastern portal are now being bored.

Joan on its second leg has been quicker than the average travel/dig rate...  right at the end of this morning's press conference (32m45s) - Evan Tattersall mentions that everything's now averaged at 40m a day (4 TBMs x 10m a day) but Joan, now on its second leg from Arden to Parkville has averaged 100m a week over the past 3 weeks.

Not sure where to post this but apparently the new platform at West Footscray is opening on the 6th of July.
https://www.ptv.vic.gov.au/disruptions/disruptions-information/article/west-footscray-station-new-platform-open-from-monday-6-july-2020

Does anyone know if there will be any trains operating from it on the day? Are there going to be any West Footscray short-starter services being introduced soon? Any bit of insight would be greatly appreciated.

I think if there were short starters, they'd say so. Besides I don't think there is capacity in the City Loop for additional services.

Services will be operating from the new platform 1 as of the 6th of July. There is currently an occo to install the point blades and commission the platform and related infrastructure. No short starters from West Footscray from sometime yet. The current platform 1 (soon to be 2) is to be used to balance out loadings for the Dandenong section of MM1. Additional AM peak services will terminate here instead of running out to Sunbury, with shorts from here to allow additional PM peak services to Dandenong. The Platform will also be used to terminate services during disruptions.

Do you think they'd do a once off service on the day to mark the opening?

In other MM1 news, Breakthrough of the new pedestrian connections between City Square, Federations Square and Flinders Quarter.

Only remaining connection is through to the Degraves Street Subway.

This is good news the project is going well now.  The connection to degraves street will this be at level with the current subway under the road?  I hope so.

Yes it will be.

There have been a couple of overnight closures of Flinders Street recently for service relocation. Late this year, early next year Flinders Street between Swanston & Elizabeth will be closed for up to six months to build the subway. It will be cut and cover as not to damage the station or the subway. I imagine the Degraves subway will be closed for much longer as plans indicate a lift is to be installed at every platform replacing one set of stairs.

Lockie91

So the plan is to open the road and build into the existing subway under the road?

If so then I can see a new intersection being built in the wall (eastern side) to the existing subway allowing people to access the subway from Degraves turning left to the town hall station?  Anyone have a map?

Doesnt sound like what Lockie said.
Cut & cover is for Elizabeth St

For Degraves St, there is already a big hole where Port Philip Arcade used to be.
That's about 50m from the old basement Post Office & subway entrance. Just need to re-open the doors and there you are.

Okay.

Cut and cover is for Flinders Street, Between Elizabeth and Swanston. Currently they have the east bound lanes closed directly in front of the old Port Phillip Arcade. Later this year this closure will extend to the entirety of Flinders Street, from the end of the tram stop to Degraves Street. This section of road will be dug out to construct the connection into Town Hall Station.

As for Degraves Street Subway, the connection will be directly to your right as you exit the ticket barriers. There is currently a couple of shops here that will soon go. This is pretty much directly under the footpath bordering Flinders Street Station. The Subway is set too be a little bit of an S shaped. Right out of Flinders Street Station, a little up Flinders Street then left into the old Port Phillip Arcade Site.(Future Town Hall) This will connect into the mezzanine level of Town Hall Station, with the platforms another 20 or so meters lower. This had to be built as Cut and Cover as it was too shallow for the road headers and there was a risk that vibrations could damage Flinders Street or Campbell Arcade.

The Development plans do not indicate any changes to the current layout of Elizabeth Street. The only change to Flinders Street Station as a result of MM1 is the instillation of 5 lifts from the current platforms into the Degraves Subway. This is being the only DDA complaint route from Flinders to Town Hall.

Draft Development Plans can be found here. Plans for Degraves Street are located in Appendix B, Plan B2 of CBD South.

I have examained https://metrotunnel.vic.gov.au/__data/assets/pdf_file/0007/231766/CBD-SOUTH-APPENDIX-A.pdf which does show some info.  If the connection is directly to the right form the ticket barriers that perplexes me.  The ticket barriers are onthe south side of the subway not the northern side.  I think the tunnel would be if anything on the northern side of flinders street to the corner (swanston or before) and thence into Town Hall.

Thanks Lockie, my bad.
Seems a convoluted expensive way to do it.
Could've just gone from the Landing thru the adjoining basements. Plenty examples in Melbourne of joining buildings and opening up useless space for retail. Owners would be delighted to open up a real archade.

But what would I know. Better to spend a few extra mill and go build a smick people tube.

Bevans, Please look at the correct plans. https://metrotunnel.vic.gov.au/planning/planning-approvals/station-development-plans

CBD SOUTH, Appendix B, Plan B.

The existing ticket barriers run the entire width of the subway. So I have no idea what you are referring to with North and South. The connection is to be directly to the right of the barriers as if you are exiting the station. This would be directly parallel to platform 1, underneath the station building and the westbound footpath on Flinders Street.

The Flinders Quarter, Federation Square and Degraves Street entrances are at the Southern End of Town Hall. With City Square entrance being the furthermost Northern End of Town Hall.

Hi John,

Im not quite sure I know which building you are referring to. I know that the snub at the end of the Campbell Arcade use to connect to a department store that was on Flinders Lane. I wasn't aware of any exsiting basement connections. It does seem a little strange to tunnel an almost exisiting connection. The current Subway does extend all the way to Degraves Place, just a stones throw from the construction site. I wonder if there were objections or infrastructure limitations that prevented them from using the current subway footprint.

probably a whole bunch of reasons why not. "Simple" solutions invariably turn out to be not so.

Could almost guarantee that every building along that strip has extensive basement. From early 20th century all those "new" builds in the Flinders St strip were on land far to valuable to waste.

The only visible reminder of the Post Office, is the signs tiled into the walls half way along, pointing to "Telephones".
Behind those barred doors is a vast expanse.
In it's day (until late 70's) one of the biggest sets of PO Boxes in the city, and the end of the era when people went to PT (public telephone) to make operator assist long distance calls. Now probably just a waste of space.

cheers
John
