Ritom Pumped-Storage Plant Project - Tunneling under extreme conditions

The Ritom power plant in Ticino, which was built in 1920 and is located only a few kilo­meters from the Gotthard Tunnel, is in need of re­newal. Since 2018, a number of con­tract­ors from the Marti Group have been working on this over­all complex re­novation on behalf of Ritom SA.

@@nipponsuxs Speaking of idiots, there are women engineers on tunneling projects around the world and a great deal of the work is brain work, not requiring brute strength. Think of all the design work that had to go into this before the TBM could tunnel a single inch. A simple error in design could end up with the TBM stuck in that crushed rock and having to be cut up and replaced in situ under the most hazardous conditions. There are many women engineers capable of such work and I am sure that some were involved in some aspects of this project. And I know quite a few women who would enjoy watching this video if their knuckle-dragger husbands would get out of the way and quit yelling for beer and food, as if they couldn't pause the video and get it for themselves.

Then there's the quality of the animation and the narration. Also just outstanding in all respects. A real pleasure to watch. Ingenious ways of showing the problems and solutions to very complex geologic situations encountered by the TBM. Perfect editing and blending of real video with animation to keep the viewer both informed and amazed. Hats off to all of you. Wish I worked for Marti!

AMAZING!!! this was without a doubt the best documentary done on a tunnel boring operation. very very cool!!

[@flomojo2u]

Seriously impressive for a corporate-produced video, it was both exciting and informative. Hats off to the engineers who drilled the tunnel and the production team!

Awesome video, well done to everyone. Being now retired from Atlas Copco Mining & Construction group regular people just don’t understand what it takes to punch through 1 meter of rock and the hard work done by underground miners and how the working conditions just beat up the most well made equipment. Again we’ll done to everyone at the Marti Group in getting the JOB done 👍👍👍👍👍👍.

Kudos to the whole team at Marti Group for both the hard engineering on tunneling and the extremely well done documentary 👏👏 Would watch any of your other engineering projects if documented that well !

that ending gave me goosebumps. I felt like huddling with those guys and give them high fives. As for the graphics, they were amazing. I've never seen something this beautifully done and explained.

Truly an amazing piece of work!! Images of both the actual tunnel and the animation were integrated seamlessly and made it possible for anyone to see and understand what was going on. A marvel of engineering and an incredible glance into what humanity is capable of. Bravo!

The animation blending seamlessly with the actual footage is impressive. Excellent video and a fascinating project.

[@feldamar2]

This was a phenomenal video. Your AV group that put this together deserve a round of applause just as your tunnelers do. Total group project. Those guys did great!

[@mortwastaken]

Truly incredible how much people, resources and engineering skills are necessary for a project like this

[@goddess9545]

The presentation and explanation is fantastic in this video. One of the best videos on the internet for practical engineering and tackling problems as they arise.

Marti Group some how has now become my go to videos for eating.

[@jazbasic]

Absolutely amazing! One of the best 32min I spent watching something on KZbin!!! I thought, let me have a quick stroll through as I work in HS2 Euston/London. But holy moly , this had me hooked and amazed all the way through. Hats of to everyone involved.

[@LDam-pf6lx]

Absolutely spectacular documentary. Well done to all the people involved in this.

[@DoryAbelman]

What a story!! This is an incredible video and I'm so happy I watched it. Thanks for sharing. The detailed explanations and animations were fascinating to watch. What an accomplishment this was!
