Is there a way to replace steel and concrete with wood? That’s the idea behind mass timber - a relatively new construction technique that’s making its way from Europe to the United States.
In the above video, you can learn how mass timber changes the construction process. Vox’s Phil Edwards visited Ascent Milwaukee, the tallest mass timber building in the world, to see how it all comes together. Many different partners have to reinvent the construction process to make a building like this a reality.

The next big test for mass timber? A ride on UCSD’s shake table - a giant table that’ll shake a 10-story mass timber building. See more about that project here: nheri.ucsd.edu/projects/2022-tallwood/ -Phil

[@KrisRifa]

Yeah, since the base structure is concrete and what looks like as much as 8 stories this is not close to being the tallest timber building in the world. The Mjøs Tower in Norway (Mjøstrånet) has a 100% timber structure and stands at 85,6 meters tall and si much more impressive than this hybrid building!

I think it's strange that Canada and the USA have a big timber industry, but instead the timber comes from all over the world. It looks to me like a big selling point if you can say you worked with (relatively) local sourced wood. Also from an environmentally view.

[@PlaystationMasterPS3]

since mass timber is catching on, I'm sure there would be a market to open a north American factory to make it out of local lumbar and supply it to building projects here instead of having to go all the way to austria.

[@cancerino666]

Unless there is sufficient demand to justify it, opening a local factory for mass timber production it's actually worse for the planet.

[@ryantetreault3447]

I think this goes back to the regulators and the manufacturing of wood. The Austrian wood was certified that it could withstand 3 hours of fire. Maybe the CANUS wood doesnt have the same properties.

[@cheeseninja1115]

it more has to do with the glulam and CLT having to be processed and made. The raw wood is made in the US and Canada, but it is not refined into the proper building materials here. I would hope these sorts of factories can be built up in the US and Canada to cut down on the possible logistical bottlenecks and bring down the carbon footprint, but that of course will take time and the expansion of the mass timber market.

[@Starblockss]

Difference is the factories and regulations, for years Timber wasn't allowed to go above a certain height, so the US and Canada doesn't have factories with machines to make CLT. Things are changing now of course, but it really starts with building code first.

I saw a few of these mass timber buildings rise here in Helsinki, two ~10 story apartment buildings and one similarly sized office building next to them. Very interesting technology.

My parents actually have a hybrid house like that. Obviously smaller, a family home, but it is built similarly. While it is great to see that buildings are built from wood, it is important to note that timber production has significant ecological and environmental problems as well. For one you can't think of wood plantations as ecologically valuable forrests. They are devoid of ecological diversity due to the use of only one crop, planted so tightly that nothing can grow under it, so they aren't habitats for animals or plants. They are also primarily spruce or pine, so conifers, which are really drought sensitive so not resilient in the face of climate change and prone to burning. these are problems we should be concerned about as well as the impact of importing or exporting plant pathogens through global trade

Very true. However. The world also needs to figure out the sand issue for the concrete structures.

Chinese helped drive that but still, something has to happen to reduce the dependency on concrete. One thing that worries me is the furthering of reduction to labor.

Really, we need to change most of industry and agriculture to use native or noninvasive plants and in a way that allows for an ecology to form and maintain itself and maybe benefit from our presence for once. If we as a species were to begin to tailor farms to be polycultures incorporated into the ecosystem then it would undo a lot of the harm done by modern agriculture and the history leading up to this. It can be done if you know what you're doing, there's enough energy hitting the ground and it's just a matter of figuring out how and getting people on board. We could theoretically grow wood in a smarter way, I'm no expert but maybe allowing some underbrush to grow and harvesting half the trees at a time in rows only big enough to get the equipment through would allow for at least some diversity to persist. It shouldn't even effect production in a negative way if it's well planned out, you can harvest the same number of trees just with half the yield each time, they would sequester even more carbon, and maybe grow faster too since the soil would actually be healthy.

Building codes aren't the problem to design, designers are. As long as the building is sound, inspectors don't care and more aesthetically pleasing designs only add value to the cities but designing the building requires accepting what the market wants. Architects have this problem internationally when they want to explore more of a country's culture but are limited by the client to look more modern and "western". That building was built to sell units, not to make a statement and a building that looks like what's trending is more of a sure sell.

[@Erik_The_Viking]

I'm curious on how the overall cost of the building would be as compared to traditional construction.

[@Tr1ploid]

Our CLT home originally was calculated to be 2% more expensive than a traditional brick home. However, due to the corona pandemic and increase in wood prices (Americans started buying up all european wood) it ended up more like 5% more expensive. However, one Russian invasion later, European energy prices are so high that the manufacture of bricks became a lot more expensive as well. I didn't know where the prices ended up, but I imagine it's a lot closer now again.

[@NotFlappy12]

I imagine it's not a very fair comparison at this point. This is quite a new process, which means it isn't as optimized as it could be.

[@matthewgarcia3356]

When talking about a skyscraper/mid rise building, it’s actually cheaper because of the lower labor costs. Concrete is cheaper than CLT, but the fact that you can build with CLT like big legos makes it much faster and simpler to build. Steel is more expensive than both of them so that is irrelevant.

This is so exciting for me as this is a dive into the industry I work in! For anyone asking why we don't produce in North America, the answer is we do, but we just don't have as many manufacturers of Mass timber products. We really need more large manufacturers. We are notoriously bad at creating jobs for the amount of timber harvested. The lead times for projects with Canadian/US companies are longer than the shipping times from Europe. We have a great availability of Douglas Fir, which can result in a higher quality slower burning Glulam than European Spruce, but we just don't have enough large manufacturers.

[@leoh5405]

I don't know any english sources but wood is a lot more porous than concrete so the insulation is way better. I think it's similar for sound as in the sound waves get trapped in all the little channels. That should improve the acoustics in a room but I don't know if it also helps to keep the sound inside or outside. As for the weather proofing: have you ever seen old wooden beams when the outer layer becomes grey? This grey layer acts as a protective layer and while it doesn't look as nice after a while the wood won't rot away for a long time. Theres wooden buildings in Europe that are hundreds of years old. As long as you don't waterproof the outside of the building and the moisture from inside can still escape wooden beams and walls will last a long time.

[@pinksylvievgc4196]

@@leoh5405 Wood works similar to Plastic foams in terms of acoustics. Wood (Balsa specifically) is used in a lot of acoustical applications due to it. Dried wood has a lot of porous areas where when the tree was alive water/nutrients would flow. Same reason why water proofing or sealing the wood is important. If the wood is properly covered to prevent water/mold growth/pests it can last for hundreds of years. In load situations wood actually lasts a lot longer than steel/metals as well.

[@scottmead854]

​@@leoh5405 Thanks! Yea, I've seen wood-based massive buildings in Japan and Sweden. And good to know about the sound-proofing properties. From what I've read, it could be as strong or even stronger than concrete. And even IF it's not, I guess some buildings don't really need to last that long in a constantly evolving world? It's great to have different options (read that stone is an excellent choice too), depending on the projects and contexts. Seems like nowadays people just care about efficiency, so they never take the time to consider other options. Build, build, build, build, concrete, concrete, concrete. Glad that some people have been questioning lately. For smaller buildings, perhaps we can also learn from traditional nail-free buildings in East Asia.

Pests could be an issue - you'd want regular inspections and you'd probably want to use treated wood. But then the same can be said for concrete and steel construction. Just look at what happened last year in Florida when water intruded into the concrete, a common occurrence, leading to the collapse of an entire condo tower.

How is this better against fire?

[@bitume]

The outer layer of the wood carbonizes, so the wood protects itself from the fire.

I'm sure it's fire treated. The building code requires a certain fire code regardless of building material. No different from a steel skyscraper.

They laminate the wood to make it fire resistant. There's no way they'd spend all that money on this tower and not think about fire. Common sense almost

Roaches LOVE glue in 90% of products 😉💢🥸

[@one_under_all]

We say its a wooden skyscraper but a big part is Oil, the Glue (makes this structures feasible [2:14]), which is from Exon or Shell. This is just replacing a environmentally bad product (concrete) with another environmentally bad product (Oil). The real problem isn’t Concrete it’s Skyscrapers, city planning, and the missing middle.

[@martin8313]

What's so bad about the wood glue?

[@antoniousai1989]

Yeah, because by volume and mass, you'd use as much glue as concrete which is basically the worst material on Earth if we talk about emissions of CO2. CLOWN. You can only complain just for the sake of it, not because you care.

[@roboko6618]

You know it's possible to join wood together without using glue or nails etc, take a look at how Japanese homes are built

[@NickNM1921]

Lots of different types of glue. I’m in school for forestry and work in the school’s construction lab. New technology is being developed to make petroleum free polyurethane glue. That being said the carbon footprint of mass timber is still significantly lower then traditional construction.

I wouldn't want to live in a wood high rise. After living in a wood condo, the transference of noise through wood is tremendous. Someone blasting the base on their speakers on the bottom floor could be heard on the top floor. No thanks. There's a reason pianos are made of wood and not steel and concrete.

[@cowboyhank456]

My thoughts exactly. I love old homes with wooden floors and details, but as an avid music listener I want to be able to blast speakers and have people over without bothering anybody around me. Even with beams that thick, I don’t see wood faring well in that regard

[@epidose]

I live in a concrete building and sound travels beautifully here too. I think it's more about specific soundproofing techniques than material.

[@choocher13]

I’m not expert but I do not think wood is more resilient to fire than concrete

[@AC-im4hi]

Well you said it. Not an expert.

[@ObiWanNairobi226]

Fire rating is to do with how long a column retains its strength. In some cases timber (specifically glulam) can actually hold its strength longer than concrete due to charring.

I too want to live in a building that smells like popsicle sticks

Jinx I just gave a presentation on timber buildings last week I am a civil engineer in progress so cant wait to contribute to the society

[@123jitterbug123]

Yeah I do not at all trust the fire safety of these 10+ storey wood structures. The coated wood products used are most often certified to only resist one hour of burning safely before they start to fail. Those on the top floors may not have time to safely escape if a fire starts at night on a lower floor. We saw what happened less than 10 years ago with the Grenville tower, hundreds of people died because of inadequate fire proofing on the outer siding. Even when these wood products have fire retardant chemical coatings, that isnt ideal for safety either. Our most potent fire retardants are also strong carcinogens, which is not something we should be coating all of our internal walls, floors, ceilings and other surfaces.

[@antoniousai1989]

What's your point? Greenville Tower was made of concrete and bricks. You're basically stating that fire can happen in any building, then how it change your choice in selecting wood timber instead of concrete?

[@AC-im4hi]

A 1 hour of fire rating would certainly not meet the building code. At least in the US.

[@ObiWanNairobi226]

Grenfell tower was a concrete building with a timber facade. Much of what you have said is a misunderstanding of how timber buildings work.
