The elevator remains stationary. They just raise and lower the building.

Ironically, it would be safer that way.

i was expecting a collapse

This is ‘old school’ jacking. Modern lift would have multiple lasers monitoring lift rate. Seems at start of video they are all jacking in unison thus lifting at the exact same rate if all jacks have the same lift per stroke. A few seconds in and that one dude has no rhythm. They will all reach maximum extension at pretty much the same time regardless of synchronization.

I was going to lift my cottage this way…, by myself…….., My neighbour talked me out of it…, he’s a good dude, yup.

It's not as expensive as people think to hire someone with experience to do. Once the jacks are in place it's a pretty easy job, they just send a guy or two in every day to pull the levers five or six times. The main risk is going to fast and cracking plaster walls and fucking up window and door frames above. Turns out most buildings aren't square, so lifting everything in perfect unison doesn't really help. You have to go slow to let the building settle with each little boost - most important with wood framed structures (what I've done this with). The video is a concrete structure so it's probably not that big of a deal. I'd be most concerned with the sloppy brick platforms. We can't see but I'd guess there is flat concrete foundation underneath them - the guys standing under the building had better hope so.

You are absolutely right about door jambs binding…, a bigger problem is mortar between brickwork …., or so I’ve heard.

I do this for a living, I actually get more use out of an Egyptian style water level than a lazer level.
Lasers don't go around corners, but you can drag that hose anywhere.

What their doing will work, but no way in nigger-raping hell would I be under there doing that!

Raising of Chicago

Highlights from the article

During the 1850s and 1860s, engineers carried out a piecemeal raising of the grade of central Chicago to lift the city out of its low-lying swampy ground. Buildings and sidewalks were physically raised on jackscrews.

In January 1858, the first masonry building in Chicago to be thus raised—a four-story, 70-foot-long (21 m), 750-ton (680 metric tons) brick structure situated at the north-east corner of Randolph Street and Dearborn Street—was lifted on two hundred jackscrews to its new grade, which was 6 feet 2 inches (1.88 m) higher than the old one, “without the slightest injury to the building.”

More "late nineteenth century" engineering that "shithole" engineering.

i bet it wasn't coordinated like this

[ - ] i_scream_trucks 6 points 3 monthsJan 6, 2025 03:39:31 ago (+6/-0)

we have entire transport companies that do this for a living.

you buy a 150 year old house from one place in certain places in australia, you jack it up, put an oversized trailer underneath it, lower it again, drive it somewhere else.

why you do that i dont know but its a thing.

Heritage.

When one nigger moves in down the street, all the white peoples move away and take the building with them!

[ - ] i_scream_trucks 5 points 3 monthsJan 6, 2025 06:00:54 ago (+5/-0)

ok i laughed a bit too loud at that, didnt think of it that way.

this is taking 'white flight' to fucking 'aussie tier' levels.

when the blacks come to town, move the fucking town and leave em there!

This is standard lifting methodology, using the equipment on hand - which does work. They don't need to by synced really, those jacks move the building like 1/4th inch up in the time you see. You do this everyday and eventually get there. The slow pace is to give the building time to settle into its new position before moving it more, otherwise you risk cracking internals in the structure above - windows, walls, etc. The reason we invented very expensive lifts and lasers to do this work is for two reasons - one, labor is expensive in developed countries and machines are much cheaper. Second, increased precision. That's more important for a $400 million building not this run-of-the-mill shit you see in the video. If you can get 20 guys to come move the jacks daily for months at a time why not.

Most likely they're not lifting it all that much - the goal is probably to clear space underneath for utilities or work on or replace the foundation.

For the uninitiated: it's pretty amazing what a simple bottle jack can do.

LMFAO!! How the fuck

[ - ] UncleDoug 3 points 3 monthsJan 6, 2025 03:07:22 ago (+4/-1)

How do they know everyone is lifting at the same rate? Or that those crappy red bricks are sufficient as bearing material?

They are all going to die.

Let's hope eh!.

Synchronicity…., is a word niggers struggle to understand precisely. Twerking in unison is not synchronization

i think it only really gets to a problem when one guy has been going spastic for half an hour, stops, looks around, and sees the rest of the pajeets on lunchbreak and his end is 6 foot higher than the rest and walls are falling off...

There was supposed to be a KABOOM!

WHERE IS THE EARTH SHATTERING KABOOM!

I was disappointed that there was no collapse.

[ - ] albatrosv15 2 points 3 monthsJan 6, 2025 06:43:32 ago (+2/-0)

Maximum i have used is 4 jacks to replace damaged logs in a building with new ones. It works.

I just wanted one jack to fail

[ - ] White_Pride_Cis 1 point 3 monthsJan 6, 2025 08:54:17 ago (+1/-0)

This was common for centuries. Look at how they raised all of Chicago. They also rotated a building in NYC 90* I believe, using this method. While I was expecting a collapse since they are Indian, this is a method that’s been used forever.

They are jackin' it.

bunch of jackoffs

[ - ] TheBigGuyFromQueens 0 points 3 monthsJan 6, 2025 05:14:52 ago (+1/-1)

I'm not in the trades, but it looks like they're using a bunch of small, hydraulic car jacks to try to raise the level of the roof to perhaps use the bricks as shims until they can elongate the pillars?

[ - ] UncleDoug 0 points 3 monthsJan 6, 2025 08:00:20 ago (+0/-0)

So a heavy duty car jack can lift a small truck at around 4.5T. What does the apartment complex weight. This idea of using car jacks on shitty bricks is just a recipe for disaster, I'd imagine there are already hairline cracks through all the major structural supports.

hundreds of tons on shitty bottle jacks

[ - ] prototype 0 points 3 monthsJan 6, 2025 08:26:16 ago (+0/-0)

Did this with jackscrews.
As others said, you can only do it a small bit at a time, over days or weeks if you want to play it safe.

Listening to the building creak and settle above you, all that weight, is an awesome experience.

[ - ] MaryXmas 0 points 3 monthsJan 6, 2025 09:05:01 ago (+0/-0)

I did this with 6 screw jacks on my fireplace hearth from the basement. I went a lot slower but it was still like playing life Jenga with a 700 pound pile of bricks. Then I put some block under it and cement. Good as when it was less old. I will have to re-do the chimney eventually but not today!

[ - ] TheNoticing 0 points 3 monthsJan 6, 2025 10:49:13 ago (+0/-0)

I hope it collapses and every single one dies.

[ - ] GroundskeeperWillie 0 points 3 monthsJan 6, 2025 12:16:18 ago (+0/-0)

You'd think they'd also have some shoring jacks under the beams as well. I dont see a single one in that fucking mess of a jobsite.

[ - ] 2plus2equals5 0 points 3 monthsJan 6, 2025 12:38:47 ago (+0/-0)

30 bottle jacks x 50 tons/ea (let's pretend)= 1500 tons.
If that is just one story it might even work.

But it doesn't matter if they are jacking in synchronicity because those shitty brick pillars are being driven into the soft ground. And since there are no pads to distribute force to the concrete beams, the small ends of the jacks will penetrate and crack it if their psi rating is too low.
Sketchy situation at best.
