The machine at 3:41 drills holes for pile foundations and the machines to its left are most likely pile drivers which insert the foundations and hammer them into the ground. The Rozelle area is an absolute spaghetti of tunnels with the metro and Rozelle interchange, it's really awesome seeing it all come together now though.
@@FormanddesignAu Sorry they are called Piling Rigs, and piles are not hammered but drilled here under the support of temporary casings (visible at 3:32). This particular shoring wall is a Secant Pile Wall with Shotcrete facing. Cheers
Also the so called "screw machine" shown at video mark 3:42 is also a piling rig similar to the other ones. The difference is that particular machine is equipped with a Continuous Flight Auger (CFA) drilling tooling which do not require temporary casing whilst the other rigs are equipped with bored pile drilling tooling which uses the temporary casing. With temporary casing we can install full length deep (up to 20m) reinforcement cages into the ground post drilling / pre concreting, whilst the CFA methodology allows limited depth reinforcement depth typically in the range of 10-15m for the large pile diameters (1.2m in this project). Here are some videos explaining these techniques in details: Bored Secant Piles ua-cam.com/video/UF9FLUioZv8/v-deo.html / CFA ua-cam.com/video/aAZoTG0EY3U/v-deo.html
Gday Paul, the 3 tall machines are piling machines. They dig deep in to the ground, remove the dirt and sandstone. After the spoil is removed a rebar cage is inserted and concrete is backfilled in to the hole using a tremie. Each pile is done one at a time in a short amount of time to minimise the chance of the sandstone collapsing in on the exposed hole.
Hey Paul, I just wanted to say that I love your content and I hope to see more updates about drills and pile drivers and hammers and the metro and spaghetti tunnels and the Rozelle interchange. Thanks my man! Keep up the good work. You are definitely one of my favourite UA-camrs.
Hi Cameron, Glad you're enjoying my videos. I'll certainly cover more of this type of stuff for Sydney Metro West and the Western Sydney Airport Line, but probably not for road schemes, as there are other things that I would like to do videos on, and there is only one of me at the moment :-)
Hi Paul, Thank you very much for the update and, no, it is not boring at all. Nice to see that, again, a company from the European Union, in this case Germany, is supplying the TBMs for the new metro line, even on the other side of the globe 😊 Cheers from Bardowick, Lower Saxony, Germany, approximately 50 kilometres south of the Hamburg city centre. Rick
Rob from Houston TX, great video Again Paul, the new graphics you are using have bettered your presentation, I been a fan and I like the fact you go into so much detail. I was a guard on Sydney Trains for 3 years, that was 7 years ago, I need to return and see all my own stopping grounds at White Bay wharf and Pyrmont! Redfern Station precent is going to be GYNORMOUS
Hi Rob, Glad you enjoyed this video and the graphics (most of which actually came from various documents). Yes its a little different now. No C or S sets anymore, and lot of Waratah trains. And yes these areas are changing a lot too!
Yes, I am planning to do more freight videos next year. Not sure if you've seen this one that I did at Sandgate last year. ua-cam.com/video/_vxeSZT3h8E/v-deo.html
Great video as always Paul, I almost forgot about the metro west project but then one of your videos pops up and I am instantly reminded of the scale of this project!
Hi Kurt, yes it's easy to forget Metro West, especially as I haven't done any metro west videos for a while. Hopefully I'll cover the remaining stations over the next couple of months.
@@TransportVlog I look forward to the metro and nearby road and park projects coming to a completion - it should all look and function rather well once completed.
Yes its looking pretty close! I think quite a few TBMS will be hitting the ground next year, both for Sydney Metro West and for the Western Sydney Airport line as well.
Hi Paul, I grew up in this area and it is now almost unrecognisable. The power station is an eyesore and should be demolished and I think the redevelopment is going to cause massive traffic problems for the area. I am again impressed by the way you keep up with the progress of the Sydney Metro. Great presentation Paul.
@@morerightrudder9742 Yes you are correct and it was heritage listed to stop any over development of the site. The locals did not want a large development which would cause traffic problems for the area and the Balmain Peninsula.
Five Dock must be progressing since your first one nearly a year ago, thanks for your terrific vids. Could you please do an update, even a short would be something!
Hi Robert, Glad you enjoy my videos! I plan to cover Five Dock again as part of a general Sydney Metro West Update. However, I've yet to do videos on Sydney Olympic Park, North Strathfield or Pyrmont, so I plan to do those first.
Always informative, thanks Paul. I think it will revitalise the area - although I’m not sure I’d call that station The Bays. Maybe White Bay, but this certainly is one massive engineering project!
Hi Andrew, the station names are "working names" at the moment. For many years, Tallawong was going to be called Cudgegong Road. So I wouldn't surprised if some of the station names do change nearer the time.
Hi Paul, I lived in glebe for many years before escaping to Tasmania, and remember when the whole area was just manufacturing, veneer mills foundries, and of course the huge sugar mill, I would really have a hard time recognizing the area now. I'm lucky enough to have been able to walk across the Anzac bridge on the first day but everything else apart from it and the power station would be new to me. I'm waiting for a really Boring video about this in the future.
Yes, this area has certainly changed. It's a little boring at the moment, with dilapidated power station and lots of earth, but it will definitely be more exciting in a few years time!
NIce to see they're starting with the tunnelling, Never dull Paul always interesting your video's thanks for the update, Wonder how long it will take to tunnel
Hi Hugo, yes there's always something interesting happening! It should reach the Sydney Olympic Park box in the latter part of 2024. Other TBMs will be launched at The Bays (going towards the CBD) and at Westmead for the tunnel to Olympic Park, so there will be lots of boring during 2023 and 2024!
Hey Paul! Thanks so much for this recent update, great diagrams and very engaging for me. Just asking, when will be the next Barangaroo Station Update? Last time was around 7 months ago if I was not mistaken. I was just purely inspired by your lovely words, and would want to see the recent update, if there is one. Thanks again, and great work! :)
Hi Jayden, Glad you enjoyed it. I had a look at the Barangaroo Station a couple of weeks ago, and there isn't much happening that I can see above ground. (I'm sure lots is going on below ground). The services buildings have started going up, but that's about it. I plan to cover some of the other stations first such as Martin Place, Pitt Street and Waterloo.
Hi Paul, absolutely loving the channel! Just discovered it an I’ve been binge watching everything!! One question - do you have any plans to look at North Strathfield Metro station any time soon? Thanks again for all the great content!
Hi Paul, great that you found my channel and good to hear that you've been binge watching all my videos! Yes, I'll probably do North Strathfield in January, and I plan to complete the Sydney Metro West series by covering Sydney Olympic Park, Pyrmont and Hunter Street as well.
@@TransportVlog Thanks Paul, can't wait! Seems we are living in exciting times.. transport-wise at least. There was a time where Sydney had stagnated in terms of new projects, but right now it's almost hard to keep track of everything, there is just so much going on! Keep doing what you do :)
In China, the metro construction usually uses a gantry crane to lift the TBM components into the tunnel for assembly, I wonder if wheeled cranes are used over here?
Hi Yitao, Yes gantry cranes were certainly used at both Chatswood and Sydenham. There is now a large acoustic shed at The Bays site, and that may well house the gantry crane.
That has been really informative. I am interested in your further updates as to where the station entrances will be. I live in Pyrmont, very close to Channel 10 & the old fish Markets. In Pyrmont we have a light rail station opposite the old fish markets. As a side note do you know how another on ramp to access the Anzac bridge from that concrete jungle hell outside of the fish market will be achieved?
Hi Hailey, Thanks - glad you enjoyed it! If you watch the videos in my Sydney Metro West Playlist, that will tell you where the other station entrances will be. I'm still to do Sydney Olympic Park, North Strathfield and Pyrmont, but hopefully I'll cover them over the next 3 months. Here is a link to the playlist - ua-cam.com/play/PLC4rJ1LEjuExEpz6b66eMVS_WzabvfJ6H.html Unfortunately, I don't know what is happening with future Anzac Bridge ramps.
According to Acciona - The cutterheads, front shields and gripper shields were originally used for the TBMs that dug the metro tunnels from Chatswood to Blues Point. So yeah, refurbished.
Yes, as DaveG mentions below, it has refurbished parts from those TBMs. For some reason I forgot to mention that! -Its mentioned in this article. www.sydneymetro.info/article/first-tunnel-boring-machines-arrive-sydney-metro-west
I wonder if the land is contaminated? Given that it was coal-fired. I'm from Perth and we have a similar situation, but the land has not been used or incorporated into anything due to the risk of contamination for the future development and nearby river (this is East Perth Power Station). Great video though!
Hi Luke, yes possibly. Often quite a lot of work happens to decontaminate the land first. I believe that was necessary for the Parramatta Light Rail Maintenance Facility. Hopefully I'll make it to Perth at some point. It would be good to cover the new Airport Link and take a ride to Mandurah.
Hi Paul, interesting video. I am wondering how they will be getting on boring out all the tunnels on our new rail line from Cheltenham to Box Hill here in Melbourne. All the very best. Rob.
Hi Rob, thanks, glad you enjoyed it. Hopefully someone locally is covering the Melbourne Metro Tunnel. Maybe start with the offical rail projects channel - www.youtube.com/@RailProjectsVictoria/videos
Hi Robert, I did one last year. If you haven't seen it, then here is the link - ua-cam.com/video/n4tAy3K6xOs/v-deo.html. I might do another one later in the year, but want to do Sydney Olympic Park, North Strathfield and Pyrmont first, as I haven't done these stations as yet.
I think its going to be a mixed use development, perhaps some apartments, some shops, maybe a museum, but all within the original heritage building. And I think it will be later than 2024 before this all happens
So much investment and so many missed opportunities. The metro will only take you two stops and dump you at Wynyard with awkward transfers to wherever you want to go. Why not more CBD stations? And why not a proper interchange at The Bays for bus and light rail transfers to Victoria Road and inner west destinations?
Hi Jack, I guess that's one for the planners. If White Bay Power Station had been demolished, that would have allowed an interchange with buses on Victoria Road. There will be a tunnel stump at Hunter Street to allow a future extension that could serve areas like Darlinghurst, Surry Hills, then head down towards Randwick, and Maroubra. That could add one or two more stations to the CBD area, although more around the edges.
It's good that Construction is well underway with the Tunnel boring machine's tunneling through to Hunter Street in the City and out to Sydney Olympic Park as well out to Westmead despite being now under a Labor Government because under a Labor Government they STOP projects like this and waste money that don't benefit the economy or the State.
I don't think the Tunnel Boring Machines have started tunnelling yet. Labour are reviewing the Sydney Metro West Project, but that won't affect the work that is already happening. It might even lead to extra stations, which would be a good thing, especially between Parramatta and Sydney Olympic Park and between Five Dock and The Bays. Once thing that hasn't changed, is that the Sydney to Parramatta rail corridor is at capacity, which is one of the big reasons for building Sydney Metro West.
The machine at 3:41 drills holes for pile foundations and the machines to its left are most likely pile drivers which insert the foundations and hammer them into the ground.
