You make the programs that i used to watch on Discovery channel, but those always felt outdated. With B1M i feel like we get to see the latest developments and the details you don't read in the news. Great!
Indeed. I always waited for the latest episodes of Build It Bigger back in those days. Glad that more people are tuning in to the latest construction projects.
Discovery Channel is a great resource that most families enjoyed before until now~ but the cable service is a high cost of learning path. If it can place in school/ institute programs ( project by project's story) that the students & families are available to learn as assignments or entertainment activities to share thoughts or getting knowledges that will be great ~ ❤ thank you for sharing this video~
They should make these types documentaries part of school curriculum. I think it teaches kids to be aware of the complexity that goes into the cities they live in, and its easy for us all to take it for granted.
They kinda remind me of some of the Open University/educational programming that used to be shown on BBC2 at 3am. I really enjoyed watching that stuff, even though I was probably too young to be up that that time. Of course, B1M content is much more engaging, and the presenter isn't some tweed-wearing professor type, with an unkempt beard and milk-bottle glasses set against a beige background. I also get hints of another BBC show, Tomorrows World. I guess what I'm getting at is that it's wonderfully produced, broadcast-quality content that pays tribute to the high standard of factual/educational programming set by the BBC (in that era, at least), and expands upon it in a creative and ultimately more engaging way.
Just like the Dutch with water, Austrians and Swiss are crazy good with tunnelling. It`s really interesting how geographic peculiarities can help define entire industries.
Austria has a rich history of tunneling. Most tunnels are built either with the New or the Old Austrian Tunneling Technique. Also quite hilarious is the valley Mölltal. It was quite big in mining, when the deposits depleted they all became tunnelers. Basically a region, where every ablebodied man works in tunneling and they are highly skilled. Practically all world records in tunneling (e.g., most meters in a day with TBM) are held by them. A friend has been tunnel project manager all around the world and he said Mölltaler are everywhere. That goes so far that they call it the valley without men, since they are always digging tunnels around the world.
When I saw the thumbnail I expected it to be about the Brenner Base Tunnel. Imagine my surprise when I found out that you did a video on a tunnel project in a city just a few kilometers away from my tiny home town of Freistadt! Thanks for covering this project.
@@TheB1M There is also a great Info-Point in the City Center not far from the Tunnel where one can inform himself about the project. Truly some good publicity work on their side.
Thanks for covering the tunnel building progress for the A26 in Linz. I drive past this every day, and I am amazed by the engineering that goes into a project like this.
No way you were there, I pass by that every now and then and was there some days ago. Incredible that you really go beyond every border to catch all the latest and greatest projects! Linz truly is an amazing city!
As a kid I worked on the Victoria line tunneling in London as a 'pony boy'. I had to push wagons filled with soil and and stone from the tunnel face back to the vertical tunnel entrance shaft. There the wagon would be picked up by a crane and lifted to the surface to be emptied and lowered back to the bottom of the shaft. It's amazing to see how tunneling technology has progressed during my lifetime!
Never thought you would cover something from my hometown. I passed by this construction site nearly every day and never thought much about it. Thanks showing some of the magic going on there.
Really loved the little graphics and animations in this one - made it nice and clear to see what you're describing. This project is a really interesting solution to the tight geographical constraints of the area, and I don't really know what else they could consider to cross the river.
As someone who is half Austrian, thank you for showing the world that Austria is a modern country, which is adapting to overcome new challenges. Also, thank you for showing the world that there are no kangaroos in Austria, on behalf of all Austrians, we appreciate it Fred!
Haha @heidirabenau511 I’m from Australia and apologise I never knew you would cop that in Austria! Wow, we don’t even have any nearby unless it’s in the countryside or in a zoo lol
@@JamesFFiTsometimes Austria really gets mixed up with Australia, we take it with a great deal of humor and we might say: "It's Austria, with high mountains - and no kangaroos" ;-) ... But there are kangaroos in some zoos of course ;-) We know, we can't compare Austria with Australia, Australia has so much more in every aspect...
@@r.guerreiro140 australis would mean that it's from the southern hemisphere. The name "Austria" came from the old Ostarichi, meaning the eastern kingdom, it was a monarchy back then. It was bigger than it's now and is to the east of Bavaria for example. The word "Austria" is some sort of a latin form of the old name Ostarichi. In German the name today is "Österreich". The name came from "Ostarichi" of course. Languages are not perfect. There are words that mean different things but sound similar. I compare it to searching for different positions on a cylinder. When you move far enough away from one point A on the cylinder, you get close to this exact point A, but from the other side ;-)
It would be really cool too see a B1M video about all the infraprojects of the philippines currently under constructions + the ones that are greenlighted and start soon and further plans. Some projects on it's own might be not as interesting but everything together might help to see the greater impact all those projects will have combined after completion.
What was forgot to mention is: That it is not only the two tunnels with the suspension bridge, it is part of the bigger A26 Linz Highway bypass project, which involves other constructions aswell.
One of my favorite channels on RUclips!! I'm a contractor and there's nothing like largest scale. I could watch this channel for hours everyday... Until I had to get something done myself LOL
I’m always amazed by the work of the western people and I learn a lot thanks to this channel, I’m from a tiny little country in the west of Africa ( Gambia) which needs more development to take place at this moment, I wish we were that lucky to have such machines to develop our country which is so tiny but lack of proper education and good leadership. This channel helped me a lot in terms of how development takes place and how important it’s I wish to cover more and more so one day I can make a change.
I love this channel so much. Everything is explained in such simple language with awesome diagrams and illustrations. I've always been fascinated by construction so thank you for the effort you've put into making this video. Looking forward to more videos!
Just Yesterday, the new "Koralmtunnel" had its first publicity train going through. Together with the Semmering-Basetunnel it will cut the drive from Vienna to Graz and Klagenfurt nearly in half. Its also further connected to northern italy and eastern european countries.
As Jeremy Clarkson once said, anyone can design something but you need excellent engineers to make it happen, solving each problem as they go, brilliant, immense respect.
i really do enjoy seeing the ins and outs of the monumental efforts it takes to bring projects like this to fruition. it makes me feel wonder and awe every time I go over or through a piece of civil engineering, because I at least half understand the work put into bringing into existence :)
There is also one tunnel under construction in the very west of Austria. (Close to Liechtenstein) The "Stadttunnel Feldkirch", also called Tunnelspinne (Feldkirch). If you translate that it would be "Tunnelspider (Feldkirch)". Because there will be 4 entrances/exits. All these 4 entrances/exits will come together and make a roundabout. :)
Apart from the clever innovations seen here, I am reminded of a time when the 1st female graduate Engineer was itself a news item in my country. About 1969 or '70. Nowadays, perfectly normal to see such a presence on a cutting-edge project. Charming, competent and in command of 2 or 3 languages. Thanx again B1M !
I’m Korean living in Austria (near Linz but where I live has way more tunnels). Korea also has a lot of tunnels because more than 70% of land is mountainous. But in Austria, there’s no radio reception or mobile data connection when you are in the tunnel and toll fee system is still not modern enough
My favorite type of content on this channel - the equipment that workers use to make engineers thoughts reality. Will (and have) watched every video this channel puts out. But the machine ones are my favorite. Keep up the awesome work gang.
$10m seems like a good deal for such a large machine. I'm assuming that doesn't even remotely consider the cost of delivery, operating, or maintenance though.
but they used 1000 of them for that one london project.... that makes 10 billion. as a matter of fact 10 million per per piece nevertheless seems reasonable taking in to account a nice house in a western european capital can reach such a price, or a new york appartement
I thought so - that’s missing I’m assuming it had to be 12” thick… - my guess the rebar was placed on the forms prior to entry and then as they said form is expanded closer
Great video. New Austrian Tunnelling Method (NATM) is being extensively used by Indian Railways and NHAI (National Highway Authority of India) in the Himalayan region to dig tunnels with width of two car lanes/ two railway tracks.
The pacing and personality in this video was really good. I liked the presentation way more than the factual und more structured normal videos. Not that they are bad at all but this video gets the channel in a great direction imo Keep it up :)
Thank you for this video. I live about an hour away from this project and appreciate the insightful view. From the outside, you don't get a sense of the true scale of it.
A welcome semi-advert for PERI. Here in Florida, we've seen some clever Italian bridge and short-tunnel tech used to expedite a new, privately owned rail line near Orlando. Most infrastructure seems stuck in old tech.
4:16 in Norway you see the bare rock in many tunnels; In those tunnels only those parts where rocks might come loose they used spray concrete to secure that part; More modern tunnels will have the concrete parts around the walls like tunnels everywhere else
I was wondering what massive project this was about, but I did not expect to see a video of the project I live 5 minutes away from. A family friend's property is where one of the ventilation shafts ended up.

Since you are in the vicinity, you should come to Slovenia. We are building a new rail line in karst mostly underground. Project is called 2nd track (2. tir Divača-Koper) or 2TDK. I belive you could make a great video about that project.
I love the videos, you make the programes that I used to watch on PBS like NOVA so much more understandable and insert the humour into the content which I love. Continue the great work!
We live right on top of the construction site next to Jägermayrhof and I can assure you every blast (of which there were naturally several a day) felt like an earthquake hahaha
Awesome video about this method. In Bulgaria this method was used to build Zheleznitsa tunnel (finished but not yet operational). When they announced it no one explained anything not even what it is. Thanks a lot about this video and I as always I enjoy this video and I would like to see more :)
@elfrjz Not sure about Jakarta, in the case in Bulgaria a land slide activated due to heavy rains right after the exut of the tunnel. Now they are building reinforcement structure and I hope by the end of the year to be operational 🤞 What is the case in Jakarta? if you know
This seems like a neat offshoot of those “caterpillar drive” machines that lay road/railway viaduct. Except instead of dropping a piece of viaduct it lifts up the tunnel lining! Pretty cool.
My goodness...engineers are so amazing. What a way to build a tunnel. Initially I thought they are going to use the traditional TBM method, and was wondering why this program is introducing an old method of boring.
B1M, you should have been invited to review the construction of Sydney's WestConnex tunnels - 22km long and 5 lanes each way at the widest point, close to the world's largest underground spaghetti junction, the Rozelle Interchange, which is still under contruction. These tunnels are too wide for TBMs to be used and mobile road headers were employed instead, cutting the top half of the tunnels first then back tracking to cut out the remainder of the rock. WestConnex is more of a tunnel network under Sydney rather than just one pair of tunnels. It is truly a global scale project which now links several previously separate surface motorways.
@@LungsMcGee There is a coal mine, or should I say, at least one, in Balmain which used to feed the former Balmain Power Station and also most likely fed the nearby former power stations at Ultimo, Pyrmont and White Bay too. This mine is close to where the Western Harbour Tunnels are being built. These power stations closed down because they were too old rather than being because the coal reserves had run dry, so I'd imagine that there is still plenty down there. There are indeed lots of tunnels - it is probably fortunate for Sydney that the whole city sits on a big sandstone shelf.
I like The B1M because it advertises stuff that is completely irrelevant for me. I’m just some dude in his 20s who likes video essays, and do nothing at all with construction.
@theb1m if you want to see the longest construction of tunel in whole world (time wise). You could make a video about Tunel called Višňové in Slovakia, which connects 2 cities (Martin and Žilina). This construction started Its journey on paper in year 1974 or 1975 and it is still not finished until now! What is more worrying is that once it’s completed it will most likely be open only for couple of weeks and then they will close it (but this only theoretical)…
I work at the Suki Kinari Hydropower Project in Pakistan. We used the drill and blast method for our 23km long headrace tunnel. At 3:07, that's a risky thing to do, placing the camera close to the excavation face during blasting! :D Mucking was done through Adits. We have special 4.5m section formwork for concrete lining. 4 of them are combined to get an 18m length of formwork. Dia of tunnel is 6.3m.
Another great video, guys. But Fred, ask Liam about the Cahil Expressway in Sydney and the massive 270 degree curve to get onto the Sydney Harbour Bridge. Now THAT'S a curve! And built back in the 1930's. Would love to know how that was done.
Oh wow, my city is on youtube, i grew up right next to that building site! I mean there is some local people who don't want this to be built but i think this tunnel is necessary and they should have built it like 20 years ago.
Thank you for covering this. I like to see Austrias great engeneers represented. There are some cool projects going on here (Vienna, but Austria in general) 😎 I'll appreciate when it will be finished, maybe I'll take a little D-Tour to drive through it sometime 😁

It is amazing the ingenuity of engineers and what they can achieve.
The ability to do the corners, and stitch all the pours together, is what to me really sets this project apart.
Fred, your videos are some of the best content on YT right now, IMO.
Austria has a rich history of tunneling. Most tunnels are built either with the New or the Old Austrian Tunneling Technique.
Also quite hilarious is the valley Mölltal. It was quite big in mining, when the deposits depleted they all became tunnelers. Basically a region, where every ablebodied man works in tunneling and they are highly skilled. Practically all world records in tunneling (e.g., most meters in a day with TBM) are held by them. A friend has been tunnel project manager all around the world and he said Mölltaler are everywhere. That goes so far that they call it the valley without men, since they are always digging tunnels around the world.
that's just down the road from me! thanks for visiting, Fred! ☺
Looks like some contraption I’d build in space engineers
Concrete does not "cure" overnight. It hardens enough to hold its shape overnight, but curing can take up to 28 days.
That varies on the mixture for the concrete

Awesome video about this method. In Bulgaria this method was used to build Zheleznitsa tunnel (finished but not yet operational). When they announced it no one explained anything not even what it is. Thanks a lot about this video and I as always I enjoy this video and I would like to see more :)
@elfrjz Not sure about Jakarta, in the case in Bulgaria a land slide activated due to heavy rains right after the exut of the tunnel. Now they are building reinforcement structure and I hope by the end of the year to be operational 🤞
What is the case in Jakarta? if you know
Incredible content you guys! Kudos 👏
Beautiful work. Well done! Hope one day I can visit and drive inside the tunnel.
This seems like a neat offshoot of those “caterpillar drive” machines that lay road/railway viaduct. Except instead of dropping a piece of viaduct it lifts up the tunnel lining! Pretty cool.
"When we say you, we don't mean YOU"
That had me laughing ngl, the tone with which he said it
Haha, you're welcome! 😂
My goodness...engineers are so amazing. What a way to build a tunnel. Initially I thought they are going to use the traditional TBM method, and was wondering why this program is introducing an old method of boring.
Austria is so gigachad
B1M, you should have been invited to review the construction of Sydney's WestConnex tunnels - 22km long and 5 lanes each way at the widest point, close to the world's largest underground spaghetti junction, the Rozelle Interchange, which is still under contruction. These tunnels are too wide for TBMs to be used and mobile road headers were employed instead, cutting the top half of the tunnels first then back tracking to cut out the remainder of the rock. WestConnex is more of a tunnel network under Sydney rather than just one pair of tunnels. It is truly a global scale project which now links several previously separate surface motorways.
@@LungsMcGee There is a coal mine, or should I say, at least one, in Balmain which used to feed the former Balmain Power Station and also most likely fed the nearby former power stations at Ultimo, Pyrmont and White Bay too. This mine is close to where the Western Harbour Tunnels are being built. These power stations closed down because they were too old rather than being because the coal reserves had run dry, so I'd imagine that there is still plenty down there.
There are indeed lots of tunnels - it is probably fortunate for Sydney that the whole city sits on a big sandstone shelf.
oh man as an Austrian I am so excited to finally see my home country on your channel 😁 We're kinda proud of our tunneling.
This is a brilliant way to cut the cost down,instead of TBM. Project like this has created a lot of employment for the locals.
I like The B1M because it advertises stuff that is completely irrelevant for me. I’m just some dude in his 20s who likes video essays, and do nothing at all with construction.
I wanna build a tunnel now
Awesome design of equipment to form the tunnel...brilliant minds to build it all...thank you for this video---WOW!!!
That bridge also looks seriously cool.
@theb1m if you want to see the longest construction of tunel in whole world (time wise). You could make a video about Tunel called Višňové in Slovakia, which connects 2 cities (Martin and Žilina). This construction started Its journey on paper in year 1974 or 1975 and it is still not finished until now! What is more worrying is that once it’s completed it will most likely be open only for couple of weeks and then they will close it (but this only theoretical)…
The B1M making a video about *TBM01*
What a coincidence )))
Fantastic documentary as always
Thanks!
I work at the Suki Kinari Hydropower Project in Pakistan. We used the drill and blast method for our 23km long headrace tunnel. At 3:07, that's a risky thing to do, placing the camera close to the excavation face during blasting! :D
Mucking was done through Adits. We have special 4.5m section formwork for concrete lining. 4 of them are combined to get an 18m length of formwork. Dia of tunnel is 6.3m.
My needed weekly B1M documentary fulfilled!
Another great video, guys. But Fred, ask Liam about the Cahil Expressway in Sydney and the massive 270 degree curve to get onto the Sydney Harbour Bridge. Now THAT'S a curve! And built back in the 1930's. Would love to know how that was done.
Another great, brief and informative report! thx 👍🏾😎
Fabulous stuff Fred. Thanks and cheers Ausgranny 🇦🇺🇦🇺🤶😁😁
Oh wow, my city is on youtube, i grew up right next to that building site! I mean there is some local people who don't want this to be built but i think this tunnel is necessary and they should have built it like 20 years ago.
Thank You ' Awesome Video Eye Opening & Very Educational .
Thank you for covering this. I like to see Austrias great engeneers represented. There are some cool projects going on here (Vienna, but Austria in general) 😎 I'll appreciate when it will be finished, maybe I'll take a little D-Tour to drive through it sometime 😁
I could watch hour long vids of this. Keep it up.
