Yes same here. Although I'm more like an infrastructure sucker. I love new shiny pieces of in infra. Of all shapes and sizes. Tunnels and bridges are on the top .

[@sueuj]

I don't know why I am learning this when I am computer science student, but the explanation was a good one

[@Someone-cd7yi]

Although I have absolutely no background in construction, architecture, engineering etc. these videos continue to fascinate me. It's absolutely amazing how human ingenuity made it possible for us to build massive cities, giant bridges, tunnels, dams etc. Incredible!

We have here in kolkata,India,metro tunnel goes inside the river.

[@maxim6088]

@NSX 55 my favourite I sthe Moscow metro, it's so deep, and it has many tunnels and doors connected to it which gives it a misterious feel...also some stations even have doors going under them even deeper, and a fact is that all Moscow bunkers are connected to each other or the metro or both!

The presentation of information on this channel is extremely professional. This is National Geographic worthy in my opinion. You guys are seriously on another level.

Another great video, Fred and the team at B1M! Keep up the great work.

[@gocarlogo]

Good job B1M! Manila, Philippines is just starting to build its first subway tunnel. Exciting times

I have little connection with the construction industry but always watch your videos. You are doing a valuable job in public understanding of construction.

Thanks to The B1M videos, I always see the end of the tunnel when it comes to expanding my knowledge on amazing constructions. Thank you.

[@petriepretorius4085]

B1M is one of the best sites i have come across on youtube...your content is inspiring...

[@michaelmains6785]

It's great to see you guys cover such an important topic. Even amongst engineers, tunnel design and construction still remains a largely specialized and poorly understood expertise. There are many different types of tunnels, not only c&c and tbm, but it would be impossible to cover everything.

[@movinperera]

Wanted to see you appear again in the video, but great and original content as always, well done 💥

THIS is the quality content I’ve come to know and love from The B1M. For some reason, the last few videos have felt kind of stale for me. But this one put you back on top - nice work! 👍🏼

Another superbly processed video B1M. I am always pleased to see something from our capital city, such as this time the metro station Smíchovské nádraží in Prague at 0:17, or the Blanka tunnel at 5:50 👍

Uses of tunnels in cities: * Transportation: road, rail, transit, in some cases pedestrian or even navigation * Water Utilities: fresh water, storm water, wastewater, emergency floodways * Power and telecommunication utilities * Large capacity shelters for wars * Making room for commercial and recreational spaces in otherwise extremely crowded cities (ex. all the shops and offices within/between rail stations in Tokyo's central areas)

[@AJCiti]

This channel is so interesting I love it

[@dirtysquirtybirty]

Hey B1M, you should make a video on Gold Coast, Australia. Not only do they have the tallest proposed buildings in Australia and a large share of our tallest buildings, but it is geographically interesting being so close to the shoreline. Keep up the great videos.

[@jesperverbruggen587]

You should do a video about the Noord-Zuidlijn metro in Amsterdam! Its a metro line in clay ground. Its a hard job making sure the tunnel doesn’t collapse

[@pedrodias2879]

One of your best videos, so far!

[@TheB1M]

Thank you!! ✊️✊️

[@aeroaa2]

3:55 wait for real ? so if I go digging around the ends of the channel tunnel I will find a TBM ? wut ?!

[@arhansalunke5361]

aeroaa2 nah remember Oceans 13 lol?

[@marsgal42]

Yes. The French TBMs were removed from the tunnels, while the British TBMs were driven out of the way and buried in concrete. Different designs. The British TBMs are now part of the electrical grounding system.

B1M you are at astonishing Levels.

[@SSarchitectful]

Great video B1M always keeping me interested :) I remember this being an issue in the Netherlands with a tunnel they were drilling for the North-South line in Amsterdam. The TBM's would be used but because they soil on which Amsterdam was built (swamp lands) caused issues with the water levels when soil and moisture would be removed. Which caused houses to sink. Eventually it was completed and they found a way to work around that issue but it was still a irritating factor for the inhabitants. Just a fun did you know!

[@andrewgnys6285]

Where I live they are boring two tunnels underneath the river to the airport. It is a massive operation and my Dad is part of it. The government have hired a Italian firm to construct them. Your video's are very interesting and I find they help my studies.

[@lakshmivenkannababujampana4037]

Every video is an absolute piece.

[@steveghawtin]

That's amazing. They could give the builder who did my extension a few years ago a few tips. Took that cowboy over a year to do that.

[@Grahameajohnson]

The B1M always provides fresh air to my motivation for photography in and around Vancouver, Canada. Thank you for such extensive analysis. I would love to see The B1M do a piece about “Big Bertha,” North America or maybe the world’s largest TBM which recently provided the catalyst to delete Seattle’s former waterfront-lined Alaskan Way Viaduct. Similar to The Bay Area, simscale might have a place in such instances.

Did you perform a simulation using SimScale?

What tunnel is at 4:33? I've never seen such a winding tunnel.

[@EnjoyFirefighting]

Really? There are much more complex and winding tunnels out there. Especially in Norway I know tunnels with roundabouts, hairpin turns, intersections and spirals

[@perthdude21]

@@EnjoyFirefighting Wow. I've only ever been in tunnels with slight curves. Didn't know there were tunnels with all those things you mentioned

[@PetrCharousek]

Don't know that one but at 5:50 is Prague tunnel Blanka. It is quite new, long enough, construction time much exceeded and in total quite overpriced

[@EnjoyFirefighting]

@@perthdude21 I have two clips showing some of the mentioned stuff; In the first clip you see 5 tunnels within 3 miles of mountain road, with the 1st tunnel having a hard right turn (basically an intersection, with the road going straight leading to a power plant): kzbin.info/www/bejne/Y3K3coGfeJ54e9E And the 2nd clip has several interesting tunnels: at 20:25 you'll see a ferry marshalling area starting in the tunnel, at 22:25 you'll see caves in the tunnel which serve as short period rest area, and at 26:16 there's a roundabout: kzbin.info/www/bejne/nWe3q5KForJ7mpo Especially in urban settings tunnels might have interesting traffic patterns; Thus I know tunnel in downtown Oslo which has a direct access to a park garage; And another place in the same tunnel construction has a halfways integrated fire station

[@Agent44996]

Here in Sydney we are known as Tunnel City, because we have plenty of tunnels and more on the way. However, a lot of them were poorly designed to future proof for high amounts of traffic back in the late 90s/early 2000s, so the ramifications are starting to show with increased traffic levels. But the new ones they are building now seem much better designed.

[@forwork7820]

Around 2:36 - i've studied civil engineering, but no-one has ever shown me how the soil is taken out of the machine and onto the surface? The machine is clearly not big enough to store many km worth of tunnelled soil. and in the video we're told that the machine is typically left in underground because it's too much of a bother to get it out. Well okay, so how does the excavated soil reach the surface?

[@alexanderfretheim5720]

They actually do mention that in the video. It's by conveyor belt.

[@forwork7820]

@@alexanderfretheim5720 I get that, but where does it go? Does it get stored in the machine and emptied later, or is it perpetually brought to the surface. If it's in the machine, why don't they ever mention the machine coming out? I can't imagine a conveyor belt taking it to the surface perpetually because there's all the soil above in the way.

[@alexanderfretheim5720]

@@forwork7820 Sorry, to clarify I mean it is carried by conveyor belt out of the tunnel. The conveyor belt runs the length of the tunnel and exits at the submergence point where the TBM boring began. From there, either an open air hole or a slope exists, and at that point it's a matter of local logistics as to where the dirt is stored or disposed of. Basically, wherever the TBM was, the conveyor belt is, and the final conveyor belt will be the length of the bored section of the tunnel. (Yes, the conveyor belt does get longer as the tunnel is bored, and the additions to the conveyor belt, from workers I have interviewed, are mostly installed by hand.)
