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.

@lignumchannel

11 ай бұрын

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..

AMAZING. What a huge work

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..

Amazing project!

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.

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!!!

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 :)

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.

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.

@lignumchannel

11 ай бұрын

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:)
