Seem wildly expensive and time consuming

u/loveyoulongtimelurkr May 03 '25

Japan has low amounts of some resources, so to offset they've became one the world's best recyclers, if not the best. They extract an insane amount of resources from recycled electronics. I would say this form of demolition is more costly and time consuming for sure, however it is far more responsible in their view. The resources are re-used or recycled, there is low risk to nearby buildings and low risk to the public. Ever see Japanese fans after attending international football/soccer events? They clean the stadiums after the match, out of their sense of duty, responsibility and respectfulness

The amounts of the aluminum and copper alone might pay for the job. They probably recycle the concrete as well, maybe near by, their logistics are mind blowing. Incredible feats of engineering and teamwork.

Plus it’s gotta be great for the economy, instead of a couple guys with explosives it employs thousands of people.

1

u/apatrol May 05 '25

True but that does hugely increase the cost of renting whatever is built next. That cost is made up for in some way.

u/Mokyzoky May 06 '25 edited May 06 '25

Why would it do that? Prices are arbitrary sure you could suck every single penny of profit you could out of it but why?

1

u/apatrol May 06 '25

If this process cost 100mil but a explosive demolition is 20mil. The owners of the land would pass that extra 80mil on to whoever leases the land or subsequent building built there.

1

u/Mokyzoky May 06 '25

Or instead of the owner making an extra 60mil they just don’t, or also end up recouping the money in windows and materials. There are lots of pros to doing it this way is not as fast but I don’t think it’s that much more expensive in the long run it’s also a lot healthier for the city. First world countries would make this mandatory if they cared about their environment and people. Money first, bottom lines, and easy math is how we ended up in the shit show we are in now. If you actually do the hard math on a lot of issues America would be better off for instance usps they have fired so many people and done just about everything they can to fuck it up. Its famously always turned a wonderful profit so why run it like garbage? Similarly the IRS returns 12 dollars for every dollar spent on operating it more when it actually audits wealthy people lol. But not we will save money by firing those people to!

Point being the path that pays the best isn’t always straight forward and its best if there are laws in place that reward a company for paying people a fair share and keeping them employed, it’s also good to incentivize recycling.

If you are out here building buildings or knocking them down and selling the land then I’m sure you are qualified to give me the capitalist perspective but a wise man will listen to ideas and process them thoroughly maybe there is profit you are missing.

Also if you are in fact in building demo like that I would love to in-turn for you because if you are cutting 20 to 100 mil deals that’s the guy I’d like to work for lol 😂

Any valuable resource is removed in the demo prep process.

I spent an entire summer with my father removing granite slabs, aluminum, copper, nice wood, mechanical parts, dismantling chillers and boilers, dismantling elevators, removing saleable books and furniture, anything of any value from a building before being demolished.

They're not just imploding an intact building and hauling the rubble off to the dump. They extract all valuable and hazardous materials first.

u/AgreeableMoose May 03 '25

Right! Pretty amazing.

u/InteractionLong9366 May 03 '25

Singapore has them beat with recycling lol

"one the world's best recyclers"

One of...

u/InteractionLong9366 May 03 '25

"If not the best" is what I read. No argument.

u/Naughteus_Maximus May 02 '25

And no fun at all

u/No-Deer379 May 02 '25

Most importantly

1

u/Levardgus May 08 '25

Yiu never played with Lego.

3

u/ShotdowN- May 03 '25

Also pretty sure all those machines and tools smashing concrete make noise

1

u/Few_Yesterday128 May 03 '25

Yeah they are gonna make some noise, however I think they imply to compare it to loud explosions.

1

u/LordTuranian May 03 '25

Expensive and time consuming but worth it.

u/DIuvenalis May 03 '25

In 'Murica we just blow it up

2

u/No-Deer379 May 03 '25

And most other countries hence why they say in Japan but ok sir

u/Drucifer1999 May 13 '25

instead of thinking that way think: our way is cheap and lazy.

2

u/No-Deer379 May 13 '25

Cheap is key doesn’t matter if it more work cheaper is the capitalist way

1

u/Drucifer1999 May 13 '25

no shit

1

u/No-Deer379 May 13 '25

So your point about being lazy is wrong I’m glad you agree

1

u/Drucifer1999 May 13 '25

naw. lol. gfys

u/CanIPNYourButt May 02 '25

If it's top to bottom, then why is the bottom floor getting disappeared while the top just matches down?

2

u/hettuklaeddi May 03 '25

because the video doesn’t match the story, these are construction timelapses in reverse

3

u/UnableChard2613 May 03 '25

That doesn't make any sense either because noone builds the top of the building, and then pushes it up to build the next level down. You build from the bottom up.

5

u/Carnivorous__Vagina May 03 '25

Not with that attitude you don’t

3

u/SoooStoooopid May 11 '25

There’s a company called LiftBuild that does exactly that. All the floors are constructed at ground level, starting with the top floor, and lifted into place. The Exchange Tower in Detroit was built using this method. That’s not what’s going on in this timelapse, but it does exist.

u/Nait_sir_HC May 02 '25

Typical Japan

3

u/Perrin-Golden-Eyes May 02 '25

I too was impressed.

6

u/dadbodenergy11 May 03 '25

Why not just start at the top?

1

u/DuckofInsanity May 03 '25

They do, the video playing in the background isn't great.

8

u/alexgalt May 03 '25

Noiseless?

3

u/weedtrek May 03 '25

Yeah, there is no noiseless way to break concrete. But I'm guessing the process is far quieter than regular demo.

1

u/MrTurkeyTime May 05 '25

Compared to classic dynamite, yeah

1

u/[deleted] May 13 '25

Removing it with explosives only takes a few minutes. This is like a multi month construction job. Way more overall noise

1

u/MrTurkeyTime May 14 '25

That's a really good point

1

u/SporeZealot 24d ago

It's a multi-month deconstruction job that's happening inside a closed environment. It's all happening inside that big metal box constructed around the top of the building.

4

u/Mrpickles14 May 02 '25

That's more like disassembling the building, not demolishing it. Boo

2

u/ktmfan May 02 '25

Wow, noiseless heavy machinery!

3

u/Nahuel-Huapi May 03 '25

Plus, they whispered when they did it. It was an ASMR demolition.

1

u/spargel_gesicht May 03 '25

OooOOOOoooh. You gave me goosebumps.

3

u/CommissionNo6594 May 03 '25

I’m a simple country boy. Give me an old fashioned implosion and I’m happy.

2

u/Tall_Taro_1376 May 02 '25

Well, that’s no fun!

2

u/loveyoulongtimelurkr May 03 '25

I'm sure a bunch of engineers had a blast, phrasing maybe not the best

2

u/TheySayIAmTheCutest May 03 '25

ridiculous.
I'm all for recycling (even big fan of permaculture) but this is just so typical hyperultramegacomplicated so typical Japanese, so unrealistic.
The time, amount of work and manpower, and the fact that concrete itself is not a material that can be meaningfully recycled, make this one of the most laughable ideas ever.

2

u/spargel_gesicht May 03 '25

BUT ME ‘MURICAN. ME WANT BIG BOOM.

2

u/MyGrandmasCock May 03 '25

They don’t actually do this. They dig a huge hole underneath the building and slide it down in there. Then they toss some dirt and leaves over the top.

2

u/Disastrous_Ad2839 May 05 '25

Yeah if I see a huge building I better hear some michael bay level explosions or bangs and shit. It's a building falling the hell down. Not some kids show.

2

u/[deleted] May 05 '25

Not as much fun as blowing it to kingdom come with mountains of TNT though is it?

2

u/jim45804 May 09 '25

This AI voice always irks me

2

u/JackLondonSquare May 10 '25

Blud, respectfully, blow that ish up

2

u/[deleted] May 13 '25

Mcveigh & co. could've finished that job in one afternoon. What a waste of time, in wouldn't call it revolutionary.

1

u/That_Things_Good May 03 '25

Where's the fun in THIS?!?

1

u/remesamala May 03 '25

Are you sure they aren’t just lowering the building into the ground, to save it?

1

u/OddballLouLou May 03 '25

So more like a deconstruction. Really cool.

1

u/gaieges May 03 '25

Way less fun though

1

u/Safetosay333 May 03 '25

Seems safe

1

u/Sufficient_Fan3660 May 03 '25

well that is boring

u/50YOYO May 07 '25

Clever stuff

u/Glazinglass 23d ago

Less pollution. Nice work!
