The level of precision on this scale from your team is insane. Everything looks dead straight with tight fits. Hard to find this kind of skilled people. Again, a perfect job. 👌
Great video as always. Really appreciate the math involved in making a project like this. Crane operator is pro! In one shot it looked like one scaffold was aluminum. Seems like a great material to use. Looking forward to the next video!
I have never thought that woodwork of this size and proportion was possible. Some of the tools used were a first to me! Man is a true monster. Excellent job!
Awestruck. I have hand cut hundreds of roofs in my career and know well the trepidation of sending the tricky pieces up to set. I also know the satisfaction you must be feeling as you stand back and look at that. Nice work man, so glad I found your channel a few years ago.
Exactly right, feels great seeing what you have made! But I must be honest though, I just want this project come to an end. I feel so bad not working on my house for the last couple of months..
What an incredible project. I love to see good strong traditional wood framing on a roof and it’s so cool to see all the joinery, fasteners, and all the tools and skills that go into such a project. Excellent work!!!!
:) Thank you very much. I'm really busy with these bigger projects atm but In a month or so, I'm getting back to my house and it needs a lot of furniture..
ufff so many things to say about this video, G. The precision on the pieces, your skills with the chainsaw at 5:51 (you make it look like slicing butter with a hot knife... man!!!😮). And the angle on the rafters... are they all different? what a torture!!!😱. And you were able to set a camera to shoot this video while going throuht all that stuf... thank you man, amazing video👍. And thank you also for reminding me to turn on CC 😉. Hey, your website looks incredible too, great pictures... by far the airport is the best to me. Cheers from Buenos Aires!!!
Thank you very much!. Yeah this project was a challenge and some beams were a nightmare to cut. Especially because I had no spare beams. Fortunately we had no major mistakes that couldn't be repaired. The roof has the same slope everywhere but the wally are not exactly at right angles so lengths of each rafter varies.. I'm just glad It's finally coming to an end. Just a week more or so and I'm getting back to work on my house..
Appropriate music might be The Iron Foundry by Musseloff. It always gave me a headache playing it. Worth looking up, but just once! Finding the percussion instruments was a bit of a challenge - particularly the half-metre length of railway track which needed a hole near one end so it could be suspended. The hammer to hit it with was easy to find.
Oh man, I totally miss your big projects. I love it. By the way what is that green liquid? coating the timber to protect from fire or just water? If you explain it I would be really appreciated.
Great craftmanship and precision work. And some creative use of the chainsaw. Love the glulam, even more when joined by bolted steel plates. A quick question: Do you know what the space under that roof will be used for?
Glad you enjoyed it:) The space will be different doctor's offices and sleeping rooms. Also spaces for work brakes, kitchens, outdoor area with pergolas etc..
Lucky first comment only by chance I assure you. Hello Again Lignum. I am sure there are architectural standards applying to these city restorations in Zagreb. What was your input into the design and reconstruction of this tile roof? Was this handled by Kamgrad Architect? How long was the prep for the project and how long was the actual time on site to build? I see similarities in the beam construction of your personal home roof construction and this commercial hospital roof. Wikipedia mentions that the hospital was established in 1942 and I was wondering if you knew when the original building for the roof you built was constructed. Was there a fire in the original roof structure? An 80 year lifespan for a tiled roof structure seems too short of a lifespan for a total roof replacement. Thank You again and once more, Great Job!!!
There were 2 big earthquakes in Zagreb couple years ago and most hospitals in city center are even older then this one and they all got damaged so there is huge reconstruction of all these hospitals currently under way ... I am guessing they are making reconstruction of an old roof construction
The building was damaged during the last earthquakes a couple of years ago. This wing was built in 1934 when building codes were not nearly as good as today.. Building is stripped to it's core so to speak. To bare bricks. A lot of concrete was added, especially to the lower floors, columns from foundations to the top floors were poured, parts of exterior walls were covered in thick rebar and layers of concrete were sprayed on top of it. We got detailed plans and a 3d model of the roof structure and our job is to build it. This type of roof structure gives a lot more open and usable space than the way it was build before. Glad you like the video, thank you for watching :)
Retired now. In 40 years in the trades. In light or larger commercial projects, never saw post and beam construction like this. Most carpenters in the US never heard of a hip beam or rafter, let alone cut one. We did, of course, on high end residential. But commercfial? larger? Trusses. Yes even hip trusses, big humongous 2x12 chord trusses, 60, 70 ft and longer. When they were going up they looked about as sturdy as spaghetti, but when anchored, braced and sheeted with plywood, pretty solid. Haven't heard of any of them coming down that I know of. Cost difference between doing it like that and the Coratia way has to be exponential. Wonder if there really is a difference in final strength. Engineers who designed the trusses would of course tell you no. I wonder. Stranger things have happened. The appearance of the mass and stability of the beams and anchoring system would make you say, o this is awesome, but after experiencing the true advantages of engineered lumber-- glue lams, tji's, even OSB 2x4's now-- I wonder.
We also do trusses, there is a couple of videos of us building with trusses. I would say it mostly depends on the chief engineer and architects and their preferences. There are many different types of building systems we use, they all have to fulfill same requirements in regards to static, fire safety, longevity etc.. Prices also play a role, although whatever system you use, different cost seems to come pretty close in the end..
Totally amazing structure and execution of great craftsmanship. Sadly, it would be a very rare thing for that kind of work to be found or used these days here in the US.
Time and the size of the beams. It would be tough to manipulate them inside the workshop. Also as they progressed with the steel and concrete, we followed them as quick as we could, It would take longer to constantly measure it, adjust the 3d moddel hundreds of times and program the robots than to build it on the site.
Love the homemade mortiser, but where is your apprentice? Edit: Is that copper naphthenate being used for the wood treatment? If so, what's the copper content? (%)
She is working on the facade on our house:)Yeah that mortiser is perfect for the job! It could use a bigger chainsaw though.. I'm not sure what are the ingredients of the solution.
I'm putting in my reservation for the open house/first dinner. Do you have a favorite champagne or is Perrier Jouet acceptable? And dress code please!.
Some architect are really cautious and I don't blame them. I did it also for my house. It prolonges the lifespan of the wood used and the added cost and work is minimal.
:) Yep, a lot. But nobody minds when it goes into health, education, safety.. But millions on fountains and monuments. That's another story.. Glad you like the work, Thank you!:)
Yes I had the same discussion with the engineer who drew all the details. He said it ensures better transfer of the load from one element to the other. When he saw how all the joint's were precisely fit, he sad they weren't necessary.. Structure was near finished at that point so we continued using them so it all looks the same..
Too weird, I was just driving to work thinking about laying out a small post and beam house, particularly thinking about the entry way, and what I would want it to look like. And then this video was at the top of my feed when I went to lunch...I never actually said post and beam out loud, so I know that it wasn't my microphone...very strange, or fate!?
In our standards in wooden structures, when you calculate the minimal cross section of a beam, rafter, post etc.. You add 2 cm in every direction for fire protection. If you get a cross section of 6x16 cm you will use 10x20cm cross section. In case of fire exposure, those 2cm turn into charcoal and protect the load bearing core so the structure doesn't collapse while the firemen are putting out the fire. These beams may seem over the top, but ceramic tiles go on top, which are pretty heavy and snow fall during winter can get up to 150kg/m2. But with all that, weight is nothing that 50cm thick brick and concrete walls can't handle:)
The level of precision on this scale from your team is insane. Everything looks dead straight with tight fits. Hard to find this kind of skilled people. Again, a perfect job. 👌
Thank you very much, I'm glad you like our work! :)
😊😊😂😂❤0pppp😅❤😊😅😅😅😊m
A very impressive project. Efficient teamwork, proper tools, nice design. Also explanations for laymen.❤
Glad you like it!:)
That is such a huge job and built to last a very long time. Thanks for sharing this with us. I hope all is well there.
Yes it is. I'ts strange to think most of my work will outlive me.. Proud and scary at the same time.. All is great, thank you:)
Great job Maestro. A symphony of power tool noise and progress. Bravo! 👏👏👏
Thank you very much! :)
I love this: "no music, just constructionnoises" thank you!!
Glad you like it! :)
Great video as always. Really appreciate the math involved in making a project like this. Crane operator is pro!
In one shot it looked like one scaffold was aluminum. Seems like a great material to use.
Looking forward to the next video!
Yes it is aluminium and incredibly light weight. A couple of people can move it with ease. Crane operator is the mvp:)
I have never thought that woodwork of this size and proportion was possible. Some of the tools used were a first to me! Man is a true monster. Excellent job!

Thank you very much!:)
you guys are good holy, attention to detail, precision. Very nice. Great wood working.
Thank you very much!
Ive said it before but you guys are amazing!
:) Thank you!
Great video! Heavy construction tools. Professional workers. 💪👍👍👍
Thanks 👍:)

Glad you enjoyed it! Thank you very much:)
Certainly did enjoy, thankyou. Love these giant adult meccano sets.
Glad you enjoyed it!:)
blimey that's enormous - great work gents
Thank you very much!
That is one huge project!!! Looking good..
Thank you!:)
Dobar posao! Hvala na sadržaju i pozdrav iz Ukrajine!
Hvala! Pozdrav iz Hrvatske!:)
Amazing professional work! Over the top!
Thank you!
I really enjoy the videos of you making the cool furniture.
:) Thank you very much. I'm really busy with these bigger projects atm but In a month or so, I'm getting back to my house and it needs a lot of furniture..
Respect. That was HUGE. Precise joints detected.
Did my best!:)
AMAZING. What a huge work
Glad you like it!:)
Nice project!
Thank you very much Ellie! Sorry for not replying earlier.. This project takes all of my time..
Impressive 👍👍👍
Thanks 👍

Glad you liked this format! :) Thank you!
Prekrasan rad...
Iako sam električar rado bi vam se pridružio samo da naučim.
Love this channel.
Thank you Chris!
Great video. Again :)
One thing that stands out: too little swearing for a croatian build site 🤣
I guess you can't hear it when speed up. Believe me, It's there.. ;)
Amazing work as always, congrats! Can you tell what's the exact type of sealant you are using at 1:27 ?
Lovely!👍
Glad you like it!:)
Oh man, I totally miss your big projects. I love it. By the way what is that green liquid? coating the timber to protect from fire or just water? If you explain it I would be really appreciated.
He mentioned that it's an antifungal "hopefully so the wood will last a couple hundred years".
Fire and bug protection. Fire protection is required by law, and the bug protection is an extra perk of the liquid.
where is the classical music? Great video!
It will be back, don't worry:) I guess I decided to try something a bit different this time..
You guys ARE good
Thank you!:)
Great craftmanship and precision work. And some creative use of the chainsaw.
Love the glulam, even more when joined by bolted steel plates.
A quick question: Do you know what the space under that roof will be used for?
Glad you enjoyed it:) The space will be different doctor's offices and sleeping rooms. Also spaces for work brakes, kitchens, outdoor area with pergolas etc..

Thank you very much! Different standards I guess.
Perfect...
Thank you!
You make it look like it's an easy job, so many skilled workers here. But how can you do this without hearing protection? :D
Could be those foam rollup type.
Thank you! I use it most of the time. Sometimes I just forget..
Just a question, for something like the cut on 10:07, why did you choose to do the cut handheld on site instead of the kuka? Logistics?
he's just showing off his badass freehand skills xD
@@mrgodBG lol it was pretty badass yeah
Time and the size of the beams. It would be tough to manipulate them inside the workshop.

Its interesting what happened with those conditioner external block)))))))
Nevertheless, this cooperative work is some extraterrestrial stuff!
Time happened I guess:) Glad you like the team!
I'm putting in my reservation for the open house/first dinner. Do you have a favorite champagne or is Perrier Jouet acceptable? And dress code please!.
:) I will let you know!
Good thing you got that dust collection bag on that belt sander... lol... look down....
:) Yeah I know..
Sois unos fenómenos, un gran trabajo
Thank you!:)
What will be used for insulation of the roof?
I would guess stone wool, but I'm not sure, It is not the part of our contract.
Why did you apply the green stuff on those BSH beams? That is kiln dried wood, it shall not be necessary.
Some architect are really cautious and I don't blame them. I did it also for my house. It prolonges the lifespan of the wood used and the added cost and work is minimal.
It's not my industry, but I've never seen chainsaws used in construction like this. Pretty neat.
Here is another Lignum video (one of my favorites!) where one of his robots uses a chainsaw:
ua-cam.com/video/KpM1_axVuaA/v-deo.html
Yep, everybody likes chainsaws, even robots:)
Seems like a lot of taxpayers money involved but it's a feast for an eye, at least. Beautiful work, as always.
:) Yep, a lot. But nobody minds when it goes into health, education, safety.. But millions on fountains and monuments. That's another story.. Glad you like the work, Thank you!:)
@@lignumchannel Agreed!
Why is that plywood needed at 10:49?
Yes I had the same discussion with the engineer who drew all the details. He said it ensures better transfer of the load from one element to the other. When he saw how all the joint's were precisely fit, he sad they weren't necessary.. Structure was near finished at that point so we continued using them so it all looks the same..
@@lignumchannel he's obviously used to working with the average Croatian builders. You guys are not them.
They probably wouldn't appreciate Mozart. :-)
Check out the deflection of the crane tower around 9:15
You should see when he unloads a bucket of sand.. The cabin moves half a meter for sure..
Какой смысл использовать древесину? Где современные композитные материалы?
Freehanding compound angles with a chainsaw? 🤯
Quickest way to do it!:)
what language is 20 x 40 cm?
I guess everywhere except the US. :)
Compairing the American building site, this is how it should be done.
It used to be. Most pre war buildings were built this way in the US before consumerism took over every facet of how we do things.
Most of the roofs here are not this heavy duty. This is a hospital and needs to stand without major repairs for next hundred years..
Too weird, I was just driving to work thinking about laying out a small post and beam house, particularly thinking about the entry way, and what I would want it to look like. And then this video was at the top of my feed when I went to lunch...I never actually said post and beam out loud, so I know that it wasn't my microphone...very strange, or fate!?
Strange things happen.. Yeah I swear that cellphone can read minds sometimes..
That is a ridiculous amount of weight on the posts and carrier beams. Why so many rafters? Purlin's could've saved on weight and costs.
In our standards in wooden structures, when you calculate the minimal cross section of a beam, rafter, post etc.. You add 2 cm in every direction for fire protection. If you get a cross section of 6x16 cm you will use 10x20cm cross section.

These beams may seem over the top, but ceramic tiles go on top, which are pretty heavy and snow fall during winter can get up to 150kg/m2. But with all that, weight is nothing that 50cm thick brick and concrete walls can't handle:)
Souping get earthquakes there?
Earthquake is the main reason why this building underwent this total reconstruction.
Did not miss music, site noise is welcome.
Yeah, Sometimes no music fits..
👍🤌
Handling that fungicide with your bare hands all day can't be good for your health...
