- Опубликовано: 16 сен 2024
- 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.
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.
Great video. Sorry about your stuff. I do like that you kept the camera running for that unfortunate event.
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.
Matt, Great coverage of this construction process. Many thanks to the crew that showed the construction process.
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.
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.
“Ooooon the Build Show!” never gets old!!!
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!
Where it all began for me. Concerns about the particle board over the years
Mass Timber: CLT, GLT, DLT, NLT, MPP, LVL, PSL, LSL... It will be amazing to see all the technologies of mass wood.
I'm so sorry about the break in. I live near SF and have had my car broken into as well. It sucks.
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 .. 😊
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.
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!
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!
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.
Wow those builders are total badasses. Thanks for the tour right in my backyard!
Absolutely love this kind of video Matt, VERY very informative. THANK you!
Wow , really clean building site.
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.
Amazing….. and WHY NOT…….. LOVE IT…. WELL DONE MATT
Yeah.....how well did the plywood bridge is sweden work out?
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.
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.
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!
your guide REALLY helped!! great learning post
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.
Great video. I hope this solution comes to Vancouver, Canada. 🇨🇦
Warren is really impressive with his wealth of knowledge and his ability to communicate everything without having to really think about it.
This is going to be a wonderful future 🔥.
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
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.
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.
Great to see how the cutting-edge commercial side does it!
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.
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
Loved the video! Sorry about the break-in
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.
I enjoyed the wood building stuff, but I also appreciate your ability to stay positive when your car was broken into.
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
Awesome stuff Matt! 😃👍🏻👊🏻
Always appreciate your support Fred!
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.
Jet fuel can burn wood beams
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.
Why the standoffs for columns? Isn't it less stable when the support surface is reduced to like 20% of the area?
It's really important to note the environmental benefits as well. Concrete production amounts to 8% of global CO2 emissions, compared to less than 3% for the aviation industry. This means that any reduction in concrete production has massive benefits when it comes to CO2 emissions.
In the analysis of climate externalities you need to consider its lifespan and other factors and not merely the energy needed to produce. As long as it can be designed to last Its a net benefit in carbon as the plywood reuses scrap wood and is a form of carbon sequestration. In a country like mine due to humidity and termites this could not work. We need to use steel, concrete or at least hardwood.
That's wild.
Try that in a small town. San Francisco is a sad place now.
I sure hope this is the future
19:00 did anyone notice the cracked wood?
Crossing GC bridge north to go to Oakland??? First time heard
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.
Awesome
0:59 and 1:17 color changing hood - that is cool technology
Reflection
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.
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:
i.kym-cdn.com/photos/images/original/000/909/051/6d2.jpg
SF what a S-hole smh. atleast you found some stuff at the end.
Par for the course on the break in being in San Francisco.
What about termite control and mitigation?
San Fran-sicko
Wow!
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
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.
Do the columns need to be "aligned" with respect to their grain direction? Like column 1 north/south, column 2 east/west?
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.
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
The ultimate treehouse!
Forgot your harness beyond the danger rail
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.
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?
Well living in Vancouver BC, I wouldn't even trust builders can make a great quality 2 story wooden house that can remotely compare with a brick built I know from Germany.. houses here change with the wind literally, Monday some doors squeak or get stuck, two days later it's a totally different set of doors with these issues and I won't even mention walking noise from upstairs.
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!
dam Sorry you got broken into. I live in the bay area. I don't go to SF anymore.
You should come see the company I work for. Timberlyne. We do Mass Timber all over Texas. We’re in Boerne.
Looks like the gangs in the area will love their new building. Hope you opted for the full coverage on your rental car.
Do you have a video on wood foundations?
A building made of plywood..... 1 billion dollar building
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
Giant Candle Stick. Guess Steel is not green enough. Foundation is concrete and steel and the rest is wood. My concern is fire, evacuation, and fire fighting. Also fire retardation and resistance. But if you are to believe the towers fell because of jet fuel fire then wood would be worse no matter how many plies.
You just hear the word wood in your brain shuts.
@@rcmrcm3370 But being so studied as you are, you don't even explain the concerns. I never understand the one line replies. Good thing you are not a saleman for this product. I heard Plywood. It is plyed wood and wood burns. It is just the nature of things. Steel melting point or iron alloys is around 2,200-2,500 Fahrenheit. So, a fire rating of 30-90 minutes okay for a 3 level but 20 floors in a place where public safety departments are getting the biggest cuts. My brain never shut down. I always err on the side of caution.
@@O.O.Guys.Othey explained in the video about the char rates, mass timber charrs at a constant rate making it easier to predict fire rating and as wood chars it forms a natural protective barrier slowing the burn. The ashes and charcoal that forms isolates the load bearing core of the wood from direct flames and isolates it from air, it’s a bit counter intuitive like the superior insulating value of unmelted snow. The reason stick frames wood houses burn so fast is because of the large surface area of exposed wood and the ratio of char rate to the small cross sections of the members.
@@jackshao126 which burns fast steel and concrete or wood and steel? Which is safer in a high-rise? What is the data? I always wondered if anyone can be honest about it or not. We just had a centuries old cathedral burn to ash in Europe not too long ago. Wood burns quickly and even treated wood to retard burn burns faster than steel and concrete. Nice building but I wouldn't get a place in it. By all means you people can. Have at it. Just don't be rude about my choice because all the char rates and that stuff has not sold me on the safety.
@@O.O.Guys.O steel doesn’t burn, it just loses its structural integrity suddenly once it reaches a certain temperature leading to sudden collapse. These are just different construction methods and both need to be tested to the same degree, granted that mass timber is newer so the longevity and potential unforeseen defects have yet to be uncovered.
It’s pointless to compare the which is safer because they perform to the safety minimums they are designed for.
Ignoring the greenwashing bs the reason for people to use wood is the speed of construction and that it is a more forgiving system ie if you drilled the wrong hole for pipes you can easily fix it without worrying about accidentally cutting a post tensioning cable.
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).
Very cool to see this system. Thanks.
buddy purchased a condo on the 7th story of an 8 story building made of laminated wood.. problem was the wack job who rented the top floor unit and was finally kicked out for not paying her rent - she set the unit on fire ..and guess what they pored a ton of water on the top floor which traveled through the building and caused a lot of swelling - he sold the unit as soon as he could ..the insurance bill will be crazy and the condo fees to repair the structure down the road ..never ever buy a wood construction condo.... just saying.
Sorry for the car break in. What a city
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.
so they could have gone with a 3 sub lvl carpark plus 17 lvls of ply?
I would be very interested in what sort of testing procedures and protocols are in place to ensure the long-term structural integrity of the columns. The composite nature of the plywood definitionally makes them non-homogenous, unlike steel, and I think the recent Ocean Gate incident has illustrated to even the layman the disadvantages to using composites in stress-bearing, structural applications. I would be concerned about delamination and the inclusion of flaws. Perhaps I'm just talking nonsense, though.
The new mass timber building types have very tight requirements, not just for the wood, but the full fabrication process. Everything from the adhesives and processing has to be tested to be sound by a panel of engineers and checked by Third parties. In terms of, life, we have wood buildings over 150 years old. We have adhesives with 75+year warrenties . In most cases the wood is protected against fire, moisture and sound by foam products. My questions engineering wise are all related to remediation. If you needed to repair part of a floor or column, or an entire level, how would you go about doing that.
If there are any major "gotcha"s, I would suspect they might be where different systems and materials come into contact. E.g. I've had garden hoses corrode and their joints weld together.
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! 🤣👍
Next time you go to San Francisco, drive a POS, don't leave anything in it! I mean it a "piece of shit", new suburban could have got you killed. DA, I'm sure you can figure out what that means!
Would it be good idea to build wood cabins ? Will it save time and money ?
little did they know that they left the most powerful and priceless book in allcreation
Awesome discovery. I’m looking into mpp for new build
Dude, that sucks. I'm sorry that this happened to you. Great episode though.
OSHA going to flag him for not being tied off. Lol
I sorry you got vandalized,Interesting building concept.
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.
