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 .
I don't know why I am learning this when I am computer science student, but the explanation was a good one
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!
European Patriot - Agreed! Human ingenuity is truly amazing!
@michael IQ is falling? Source?
I worked on a project and the tbm shaft is 64 metres deep when your around the construction its amazing
@@MotokoTai haha the sources say add 5 more
@michael No it isn't.. it's actually rising if you were to ask someone.
Metros are one of the most interesting and fascinating thing in a city for me :).
We have here in kolkata,India,metro tunnel goes inside the river.
@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!
I like weed that's all nic profile pic bro
Same!!!! I'm fascinated with metros/subways
guess Tokyo must be heaven for you :)
B1M is truly in a world of its own.
I've never quite known why but I've always loved tunnels, there's just something exciting about them
Plxton feel the same way
Me too, there is something magical and mysterious about tunnels, ever since I was a kid I was fascinated with tunnels. 😏😏
@@toddhunter3137 Me three - there's something, i just can't put my finger in it, I mean ON it.
i feel the same!
I love the idea of traveling through tunnels too!
Another great video, Fred and the team at B1M! Keep up the great work.
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.
Admit it, you searched for it.
Yeah😅
Certainly did
Yes, I did
In the middle of my exam preparation. I had to know
Good job B1M! Manila, Philippines is just starting to build its first subway tunnel. Exciting times
Good job guys
Keep it up
God bless all the subscribers
Pun intended?
Wanted to see you appear again in the video, but great and original content as always, well done 💥
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 👍
Having worked as the Architect on the design of many above and below grade public mass transportation system projects in North America, I want to thank you and your team for having provided the public a very informative video that is a visual "gold medal"! Tunnel construction in complex geological strata along with constant and varying hydro-static ground water pressures are but the start point for all tunnel work. Again, thank you for the animated computer models, as these models are necessary for the public to fully understand the complexity of tunnel design and engineering. Modeling the sequence and phasing of construction and operation of the mass transportation systems is now a necessary component of the design process so we may comprehend the dynamics of moving thousands of people safely. In addition to a construction staging and sequence model, the design community now embraces the need to three dimensionaly model tunnel fire and smoke control systems. To visually simulate the containment and compartmentalization of a fire through pressurization and smoke extraction is now a necessary part of any underground project. Although fire suppression and ventilation systems of today are but one component of the overall life safety system of a tunnel project, we must continue to build better computer models in order to simulate the dynamic interplay that emergency conditions create so that we limit any loss of life.
Again, thank you - Michael
Honestly I expect new architectures and tunnels to have ZERO loss of life. Anything more due to design flaws or negligence is unacceptable. It is one of the reasons I went on to be a computer engineer rather than a civil engineer which I was both interested in. Yes, I realize my code could cause deaths but not directly since it is for telecom products. Good speed, MM.
Keyboard liar who consulted Wikipedia and google
Mr. Murphy, feel free to connect with me on LinkedIn! I may want to pick your brain at some point.
Where can I learn tunnel construction
@@rio.thethantom same question bro. Mr. Michael can you help us in this matter ?
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.
I've been looking forward for B1M uploads
Always been fascinated by tunnels. Especially from growing up in Western Norway were there are a lot of groundbreaking tunnels and tunnelprojects.
My favorite day of the week cos you guys are back! Great work guys!
B1M is one of the best sites i have come across on youtube...your content is inspiring...
I love your videos guys, The quality, information and visuals is always fantastic. Look forward to your videos each week, great work!
I have little connection with the construction industry but always watch your videos. You are doing a valuable job in public understanding of construction.
I swear this channel just keeps getting better! Love it
Thank you so much! 👍👍
This channel should have over a million subscribers.
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
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! 👍🏼
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)
I would love to see a video about the massive dams the Netherlands has build in recent years to claim more land mass and prevent the country from flooding. These are such massive structures!
Please Do it, B1M.
This was VERY ENLIGHTENING! Thanks, Fred!
DID,n,t anybody ever have a suspicion of all the rubble or new materials going there .
Ll
This channel is so interesting I love it
Favourite channel of civil engineering students...
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.
This channel deserves more views and followers.
One of your best videos, so far!
Thank you!! ✊️✊️
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.
I’d love to see you cover the new WA-99 tunnel that replaced Seattle’s Alaskan Way Viaduct. Great content
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!
3:55 wait for real ? so if I go digging around the ends of the channel tunnel I will find a TBM ? wut ?!
aeroaa2 nah remember Oceans 13 lol?
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.
@@marsgal42 didn't they meet half way?
B1M: We share this info so you can expand your knowledge ^_^
Some dude on RUclips: Woah, I wonder if I can steal it!
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.
Every video is an absolute piece.
B1M you are at astonishing Levels.
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.
Good one! Tunnels are underrated section of infrastructure.
B1M there is something about your narration which makes your videos so interesting.
I knew how TBM works but the way you explained it was amazing!
As always keep up the good work.
Amazing engineering and amazing workers!
I love this channel. It single-handedly doubled my interest for city design & architecture. Thank you ❤
Amazing! I would love to see one of your clips on the history/construction of the SMART tunnel in Kuala Lumpur and its very interesting ongoing use
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?
This is awesome to see how tunnels are constructed. Thanks B1M!
Malaysia also use this technology for public infrastructure in Kuala Lumpur..
Was waiting all week!
A fantastic piece of information
Sir, could you also make a cost, safety, and social comparisons?
Powered by Simscale?! Yeah!
Yihaaa! :)
Maybe more tunnels could be built to get from one side to the other side including more road tunnels such as the Silvertown tunnel and a new road bridge to connect the North Circular Road and South Circular Road in East London.
Sempre molto belli e interessanti i vostri video. Grazie 😊
My favorite channel
I love the fact that you added some videos of the Bucharest Metro! I mean, I was pleased to see it, but out of all of the countries in the world that have metros you chose Romania?! To be honest, even I wouldn't have done that and I'm Romanian... Such a shock, I know :))
another option ti improve air quality in road tunnels: an air treatment plant; As far as I know, only the world's longest tunnel, the Lærdal Tunnel in Norway has an air treatment plant so far.
It’s so fascinating how you have basically a multi purpose train that breaks, forms and even sprays concrete....
Interesting content and well presented. Thanks from Orlando. We don’t have any tunnels.
Would be interesting to do another video how tunnels like Seikan Tunnel below the seabed of Tsugaru Strait was built.
Paused it at 1 second... just getting my notepad to count the “in response” references. Oooooo... so excited!!! 🤗
#B1MEXHILARATION
Zero 🙁
Very Informative Video and your animation is so great I am very pleased to see it
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.
enjoy the video, i recent used mount blanc tunnel from italy via france finally switzerland
Pedestrian access to tunnels is exciting. It is historic.
Great information. Thank you. 👍
this video makes me proud to be a victorian with all our infrastructure work happening
Your channel is very addictive
Like so much!!!
There is always a light at the end of the tunnel.
Liam Walsh Sometimes there is no light but a TBM... : (
Liam Walsh A train maybe?
This video was too short for my liking, ...so I clicked replay 😁
Firstly, let me congratulate you for this amazing content you post weekly.
Secondly, a question: what do you suggest is better for a city, an underground metro or above ground one?
Amazing video as always!✌️
Nice work!
Don't forget about tunnels for utilities, most notably large aqueducts, combined utility tunnels, and large sewers (storm, sanitary and in the past combined). These make living in huge cities possible from a sanitary and modern living standards perspective.
Another great video.😉
Bro! Good job. Could you talk about geotechnics?
The ingenuity of man.
The Cut and Cover method was used to Finish the bulk of NYC's Subway system in only 4 years. It is disruptive but can be a faster way of building such systems.
Yes, and if you build the tunnels under minor streets, it doesn't really disrupt traffic that much. Minor streets also have the advantage that they tend to be more pedestrian friendly. I think the real reason it isn't popular is voters can't understand why building the subway under the less significant (but largely equivalent in terms of where it takes you) road actually makes logical sense. New York, Boston & Hong Kong were all built by the free market and corporations making profitable decisions, while London was built by a highly logical aristocratic society of stakeholders who personally benefited from prosperity and success - none of the great systems were built by voters in a democracy.
7:01 My country is now planning to built a single-bore tunnel with a dividing wall in-between instead, to avoid the cost & complexity of building passageways connecting both directions of traffic flow
Big fan of B1M. question - how many companies are there that own TBM's????
A Case study video on a significant tunnel would be amazing
You should do a video on the Eisenhower and Johnson tunnels in Colorado, the longest highway tunnel at its time, and to this day the highest.
Excellent video
this right is a ligit channel which is way ahead of others
Had the opportunity to see and touch City of Atlanta's Driller Mike TBM, building a water supply tunnel
Thank you PRRD. Soon, Manila has its own subway.
TBM's are not the only method of tunnel construction in urban areas. Many (if not most) are constructed using road headers.
If the B1M ever wishes to talk about any other aspects of the industrial revolution? it would be most welcome ;)
That Sim Scale program is pretty cool, but complicated to learn.
Learnt a few new things.. thanks
This should be a podcast
I love your videos mate
Craig F. Thompson Brit
I like your videos a lot, I would like to see how the Singapore infrastructure looks, in especial the public transport system and how it is vital for the citizens life
Thanks for getting to the bottom of this, Fred and team! (pun intended)
6:35 Melbourne Metro makes B1M.
When one direction of the Eisenhower Tunnel is closed, and both directions of traffic have to use the same tunnel, it can be unnerving.
THE OPEN BOOK OF KNOWLEDGE ; WHERE OUR MIND GOES ON A JOURNEY THRU DIFFERNT ASPECT IN OUR DAILY LIFE, THE B1M...
I've been on trains through the Channel Tunnel. It feels like any other train running in a tunnel, except that it doesn't stop and you have no idea how far under the surface you are.
Impressive. Very difficult and expensive to pull off
Hello make video about tunnel from Germany too Denmark. Longest ever built, and it's coming 😀 thanks for the great video's.
Great content as always. Keep it up!
Just a question though out of curiosity: Why the name "B1M"? Does it stand for something?
Thanks for this valuable video
