- Matt is in downtown Oakland touring a very unique job site. The support system and floor of this 20 story skyscraper is made almost entirely of wood and you won't believe how fast it is going up! Is this the future of skyscrapers as we know them? Comment below what you think!
Huge thanks to owow.com for giving me a tour of this amazing project!

"I'm thankful for that."
Overall very interesting video. Although, my biggest takeaway is how to be positive and gracious even in unfortunate situations. Good job Matt!
Fabulous tour!! Middle /low income housing ,built in 2/3 of the time. Seems to be an answer to the homeless problem. There are many,many working homeless. What a great thing.
There are over 13 million empty houses in the U.S. The are about half a million homeless people. New housing is good, but removing tax deductions for empty rentals would do a lot of good too.
@@MaskOfLoki634 Amen to that brother.
@@MaskOfLoki634most empty houses are not in habitable shape. They need to be and rebuilt.
You also have to factor in underhoused people that are not technically homeless, but that are living in a single room instead of their own apartment. Once you factor that in, the USA needs 30 million more houses.
Great video. Sorry about your stuff. I do like that you kept the camera running for that unfortunate event.
Damn, nicest Contractor I have ever seen. A wealth of shared knowledge, in a way which nearly all can understand. OWow has a good partner there, and sounds
like a quality housing creator. Congrats Oakland CA! (land of the first legal micro-dosing for PTSD and an apparently forward thinking city council.)
That's the beauty of Capitalism in a Republic, you can make as much money as you're willing to work for then you can spend that money on quality people like Matt.
My dad's an engineer and he's been talking about wood sky scrapers for as long as I can remember.
They still come with a lot of concrete as core and floor.
@@Braun09tvnot always. Concrete is always required for a foundation, but CLT can go upto twenty floors without major steel or concrete structure besides the foundation. You loose a lot of volume with CLT on the lower floors though. CLT is about as strong as carbon steel per weight, but steel 10 times as strong per volume, so steel skyscrapers need far less thick space for support. CLT skyscrapers out of pure wood will have around 2-3 meter/ 10 feet wide supports on lower floors, and they get thinner towards the top. Wood type also makes a huge difference. Wood strength can vary 10-50x dependent on knots and wood species. So wood skyscrapers can be a bit more of an artisinal board sorting venture.
@@viewer-of-content and, wood skyscrapers seem to not have any financial advantage ever.
@@Braun09tv I think it's mostly a quirky building type for now. Wood and tons of sprinklers are the cheap go to for 5&1 construction in the USA. And the only reason it's not also cheaper to go higher is lack of approved materials in volume, firecode's slow adjustments, and lack of builders/buyers familiar with it. I'm not sure if mid and high rises will ever be as cheap to build as a suburban 5&1 per unit, but I don't know what the future holds. Also look up fire testing CLT it's crazy how the fires just put themselves out. CLT is designed with a 1-2in sacraficial layer of wood around their circumference when exposed to meet fire code. It's such a weird design that I kinda think you might be right on more expensive for the rest of my lifetime, I'm guessing thats another 40-70 years from today based on my family history.
This is really interesting! I'm a structural engineer, I mostly do residential, but we did have a Rothoblaas rep come present to our company a few weeks ago. Mass timber seems super interesting, I haven't been able to work on it, but I really appreciate being able to see a video of one under construction! Sucks that your car was broken into, though.
Matt, Great coverage of this construction process. Many thanks to the crew that showed the construction process.
Love seeing wood being utilized in big commercial buildings! I can’t imagine being the one responsible for giving a quote to a job this large and complex. Definitely got to know your numbers well!
In Norway we have a couple of tall wooden buildings, for a little while we had the world's tallest. In any case, on the inside of these buildings, there is a lot of exposed wood, and it is in a way part of the design of the house. It was strange to see that these covered with gipsum.
it's for fire rating they talked about it, building this size needs a certain fire rating than something smaller
@@poopee34those columns meet fire rating without being covered, but the city’s zoning doesn’t believe the scientific testing, so they are forcing the builder to waste money and make the building uglier based on feelings, not science. That’s why they talked about getting city approval to use less unnecessary fireproofing. It’s amazing how many building codes are not based on anything factual but feelings.
Norway also had the largest wood bridge collapse
@@benchoflemons398 Correct. Apparently due to poor design.
Some diagonal beams had 200% of their calculated safe load. The error was discovered in 2016, but forgotten.
Wow those builders are total badasses. Thanks for the tour right in my backyard!
Warren is a friggin rock star. What a pro. Dude is a builder, for sure.
Really interesting for all the mechanical connections. Simpson sales rep is living large.
Absolutely love this kind of video Matt, VERY very informative. THANK you!
your guide REALLY helped!! great learning post
I pushed this video off until I could watch the whole thing in one sitting, and aside from a mildly tragic ending, I'm glad I did. Neat blend of old school and new hotness in that building. Hopefully it works out well for its tenants. Thanks Matt!
“Ooooon the Build Show!” never gets old!!!
Wow , really clean building site.
I'm so sorry about the break in. I live near SF and have had my car broken into as well. It sucks.
Mass Timber: CLT, GLT, DLT, NLT, MPP, LVL, PSL, LSL... It will be amazing to see all the technologies of mass wood.
Hey Matt! Come check out our MPP hotel in your old stomping grounds in Portland.
We are working closely with Freres and using their MPP. You should check out their manufacturing plant!
Great video. I hope this solution comes to Vancouver, Canada. 🇨🇦
Like seeing a commercial/high-rise project on your channel. Nice change of pace.
Matt, I appreciate you taking us on this tour. I'm glad I clicked.
Loved the video! Sorry about the break-in
Matt, if you are going to Oakland you're using the wrong bridge! 😂
I was thinking just that!
Unless you want to go over the Golden Gate Bridge.
looks like the hybrid wood structure method. my concern is the water management. especially as its more critical with taller buildings. especially if you have guys who are used to one method then having to build a different method. i suspect the early ones they will pay attention to, but as complacency sets in, all the usual errors start coming into play and you may see leakage and the usual rot.
so how long before these become leaky home syndrome.
It probably isn't such a big deal if they are cladding in curtain wall glass. That could give you a capillary break from the structure, and it is a pretty solid system for sealing and water shedding.
This.
Laminated lumber looses structural capacity so fast with water exposure. I see so many leaks in large buildings and houses that arent even noticed until its too late. Wood skyskrapers is scary.
@@eh_bailey not always the case. i think it was BSFC who did a post on a high rise building that leaked due to fastening details. if that was wooden instead of concrete, especially LVL, its a major problem.
Di base il capo cantiere , il responsabile dei lavori é pagato proprio per controllare i problemi da te elencati .. 😊
Amazing….. and WHY NOT…….. LOVE IT…. WELL DONE MATT
Awesome stuff Matt! 😃👍🏻👊🏻
Always appreciate your support Fred!
Yeah.....how well did the plywood bridge is sweden work out?
Cool building, just goes to show how much goes into these huge buildings in thought and time. That ending was unexpected, but not surprising I guess.
That's wild.
Great tour! Nice to see this type of more sustainable construction being adopted. I think the next step would be for the facades and interior walls to be made from timber, as long as the regulations are actually clear to follow I think the economics can improve.
Sorry to hear about you getting robbed. Unfortunately that seems to be one of the many differences between California and Texas.
Where it all began for me. Concerns about the particle board over the years
Thanks for that great walkthrough! It's almost funny to see how many viewers and followers of yours are so scared by this type of approach, especially when it almost certainly has countless hours of research, development and certification behind it. I have some questions still, but it's definitely intriguing and I will absolutely be trying to find out more about it.
Great to see how the cutting-edge commercial side does it!
Matt, come up north to DFW area. The colony/Frisco area across from Toyota HQ building off 121 they are doing the same thing, building is made with wood.
that blows about the break-in. Cities are getting worse, out here at least.
There's a CLT building going up right down the street from where you were. Owow and Web-Cor makes for a very innovative team. For beautiful CLT building check out the one in across the bay in Redwood City as carpenter it will blow you away with all of the exposed wood. And if you are a fan D-Fir wood the Cathedral interior is a must see it pays homage to Jesus the carpenter .
Malcolm from Oakland
Warren is really impressive with his wealth of knowledge and his ability to communicate everything without having to really think about it.
If a unit on floor 15 floods, how does that effect the other units.
On concrete construction high rises. You can have many units flooded from above, and it’s no big deal, just concrete and steel stud. Dry it out, all good. But wood? It will bloat, deform and cause structural issues. Not sure this is a long term option that one could call wise. Also, as someon who has worked on all things timber frame in the GVRD, I feel I can safely say that lower rise options are best for wood, but there are lots of other options and maybe we should be saving all this plywood for regular plywood consumption. The amount of fasteners you need for timber high rises is kinda crazy.
Also, I’ve worked on a specific kid of 2by8 mass timber where they are sandwiched together for a solid floor.
You could hear a nail drop on the floor from a unit above.
Yes it's concerning. They will tell you we have moisture barriers, this and that. All good when the building is brand new, but we all know these things fail eventually and you need a plan B for when that happens. In old building with solid wood the water runs through and the wood never stays wet for long.
Definitely not expecting you to get robbed! What a miserable end to a fascinating episode; glad that you were able to recover at least some of your things.
SF for ya
@@vapeurdepisse I did, living in the bay area I could tell you it was coming.
At least he laughs it off.
Lol totally common for Oakland and SF. Nightmare. I won’t go into our offices there anymore. Not worth the risk.
Literally my first thought was getting robbed
I'm digging the "on the road" music
You should have come to Milwaukee. The tallest all wood building is being finished now. I am sure it won't hold the title for long.
19:00 did anyone notice the cracked wood?
Wow!
There’s a building going up made of similar material in Austin at East 4th between Waller and Attayak street. It’s three story but takes up the whole block.
Awesome
I sure hope this is the future
This is going to be a wonderful future 🔥.
Very cool to see this system. Thanks.
I can’t say I’m surprised that the rental got broken into where you were filming. Sorry about your stuff. I think it’s interesting how what’s most to them is perhaps least important to you & vice versa.
Jet fuel can burn wood beams
Jet Fuel doesn't melt NPP columns :)
Not as fast as steel. I bet you're one of those Hicks who can never start a fire out in the woods but then you start the complainant wood is so easy to burn.
@@rcmrcm3370 it's a joke. The 9/11 pony meme:

The ultimate treehouse!
Sorry to hear about the crooks breaking into your rental car. We moved out of the S.F./Oakland Bay Area three years ago as we saw crime statistics rising. We are building our dream home three hours away in the mountains using materials and techniques we learned from watching your channel. Never thought I would see a wooden skyscraper! Keep up the good work!
This was a super great video, I can't share my excitement. This levels the playing field for mid-rise contractors to move up to skyscrapers. The only thing that I would be curious about is the walls separating the units. Do they use the same mpp product for wall separation or do they use traditional framing like steel or wood? Also what is the product that they put down before the concrete on the floor?
Per IBC this is Type IV-A HT construction. While HT (Heavy Timber) would be allowed for the various partition walls, lightweight lumber (2 x X) would not. Non-combustible is the normal allowed interior wall material, practically meaning steel studs and GWB. 1-hr rated between apt/condo units; rated hallways etc. You’d need to see full plans to be really detailed. So HT walls are still an oddity in Type IV construction.
You need to replace your navigation app. That's not the best way to get to Oakland.
I'm wondering how much they were able to reduce the concrete floors because the floors above were (I'm assuming) lighter in weight.
You could not pay me enough to live in one of these piles of firewood.
Agreed but... All houses in the US are piles of firewood
Do the columns need to be "aligned" with respect to their grain direction? Like column 1 north/south, column 2 east/west?
That’s the long way to Oakland.
I enjoyed the wood building stuff, but I also appreciate your ability to stay positive when your car was broken into.
San Fran-sicko
Crossing GC bridge north to go to Oakland??? First time heard
Only concern is having a small connection point at the bottom of the column. This will introduce a rotational force in the event of an earth quake.
Do you have a video on wood foundations?
0:59 and 1:17 color changing hood - that is cool technology
Reflection
What about termite control and mitigation?
Could you address the delaminating column right by you guys at 19:42 ?
Wow I just noticed that, You wouldn't catch me being the test dummy, Being the first living in them
Sorry for the car break in. What a city
Par for the course on the break in being in San Francisco.
Why the standoffs for columns? Isn't it less stable when the support surface is reduced to like 20% of the area?
They don't only have good weather up north. Oakland is a particularly dangerous part of town. Sorry you had to experience that but I'm sure you learned a valuable lesson. Otherwise. awesome video, as usual!
I sorry you got vandalized,Interesting building concept.
You should come see the company I work for. Timberlyne. We do Mass Timber all over Texas. We’re in Boerne.
SF what a S-hole smh. atleast you found some stuff at the end.
MATT: I've been following the development of larger wood framed structures. If you haven't done so, or not recently, would you please discuss the sources of all this lumber....I'm a retired builder, so kinda out of touch now-but historically, here in northern New England, framing lumber has been SPF, with increasing amounts of engineered lumber. Southern pine for PT and some douglas fir more recently in the Boxes. SPF was typically sourced pretty locally from the North Woods of New England and Quebec, Canada. These forests have typically NOT been managed for enduring productivity. WHERE is all the lumber from for these multi-story projects going to come from, certainly not the Northeast?? Cheers
If this stuff was imported from Austria, all bets are off.
Forgot your harness beyond the danger rail
We had a (tiny) 4 double story (8 story building with only 4 floors) timber framed building (completely glass-curtain facade - the lift shaft/fire escape unit was poured concrete) built in my home town in Australia a couple of years ago - I was fortunate enough to be able to do all the progress aerial photography, the sad thing is all the components had to be imported from Europe as there were no glulam/ LVL presses big enough in Australia - doesn't seem like "rocket science" - but the investment in manufacturing facilities for the columns and beams isn't trivial..
The construction was not a lot different to making a multistory workbench, (posts, beams, deck- repeat many times and fit out...) very few structural components really, just more than at least 3 times bigger. (if a workbench were a mansion for ants). (The concrete lift shaft/fire escape provides the real stability to the assembly).
OSHA going to flag him for not being tied off. Lol
Would it be good idea to build wood cabins ? Will it save time and money ?
Wood bends then gets its shape back so why not. The trick to wood is processing it right, you gotta dry it out with high heat I believe they call it "engineered" nowdays but I'm uncovering wood that looks imaculate and it says "oven baked" on it or something like that.
Wood skyscrapers are vertical tinderboxes.
Non-high rise wood buildings are tinderboxes too, but at least the occupants are closer to the ground in the event that they need to evacuate due to a fire.
Theres this great invention called Fire Sprinklers, 99% of commercial new construction has then.
A building made of plywood..... 1 billion dollar building
Dude, that sucks. I'm sorry that this happened to you. Great episode though.
Well they will burn fast.
Actually they won’t.
@@suspicionofdeceit sure believe that and the sun will never set
Matt, impressed with your attitude when dealing with disappointment of vehicle being broken into. You carry a Bible and religious book - must be a practicing Christian, eh? Nothing wrong with that.
Favorite quote: Circumstances don't make the man, circumstances reveal the man.
He's not gonna lash out on camera
THIS is a “bomber” build Matt !
At one point that steel floor strapping/seismic bracing had it's integrity compromised with that half moon cut through it for the pipe hole - That would be an instant fail during my building inspection.
Wow good catch. No one seems to care about drilling holes in structural components
@@vapeurdepisse Ive literally seen builders I worked with heating and bending structural rebar in foundations and columns an hour before a concrete pour inspection ... Never fails to amaze me how bad the industry is at times.
Well Matt you see where you first went wrong was thinking you could go film in San Francisco. Do you pay any attention to the news?
little did they know that they left the most powerful and priceless book in allcreation
dam Sorry you got broken into. I live in the bay area. I don't go to SF anymore.
Looks like the gangs in the area will love their new building. Hope you opted for the full coverage on your rental car.
How cool, like building a tree 😅
Try that in a small town. San Francisco is a sad place now.
My guess is, the guy with the beard is the crane guy, he exist on every construction 🚧 site.
Is anyone old enough to remember when building with wood was considered bad because we were cutting down all the trees? And a lot of loggers lost their jobs. Wasn’t that supossed to be environmentally friendly back then? And save the planet?
Nope, never happened.
Il cemento è 100 volte più impattante del legno .. se tagli il legno e lo ripianti si crea un ciclo
Not much span space between the MPP columns
You are walking the walk, as they say. Beside the feature build presentation. The incredible disposition you managed to maintain having been slammed immediately from just concluding a high experience "MPP" is more of a "WOW". I believe you have a deep sense of peace in your person. Your choice of reading material may be on the best sellers list. God Bless You.
I always thought it was cool that we built houses in America 100% framed out of wood and it stands for decades but skyscrapers made of wood????? That’s mind blowing 🤯
All the Milwaukee batteries
there was a 20-story wooden skyscraper built in sweden several years ago, and it's worked-out great apparently. 😎👍
In high populated areas like here in the United States this isn’t smart. Here in the United States, we already had a mass tragedy because many buildings were made out of wood next to each other
@@vicdiaz5180 lol, sweden is far more densely-populated than the united states. 🤣
@@douglasharley2440 dont listen to him he’s living in the 1800s not all americans are that dumb 🤣🤣🤣
They don't have the riots, fire burning, molotov cocktail throwing folks we have here.
@@pennyhinson4949 or the attempted fascist takeovers of the country, either! 🤣👍
