Absolutely the best music for a video like this. Tight drum track and solid bass groove. I was to busy rocking out to learn anything.

Beam less slab. Great animation, really informative. Thanks

The engineers that figure this stuff out...respect.

Awesome animation...

Thanks for the vedio. That was a great construction.

So good animation!

Very nice system. Thank you🌹🌷

TY for kind comment. Ivica.

how does the mechanism of this hydraulic lifting system work? is there a video?

Great..

great video

Names of buildings which have this construction ????

The weight of those slabs is mind boggling. How much curing is needed of the concrete before lifting?

@videoproduction4u897

This could be normal concrete slabs without any special curing. Sorry for the delay. All the best, Ivica.

Is it frightening working underneath the slabs; or is it just me? The mind does funny things with those that work in areas with history of serious seismic activity.

just curious, are they going to cut holes on those slabs for the path of the stairs after?

This is just an animation. In reality, slabs are produced according to the project with holes for steps before lifting. All the best, Ivica

Is there a technical document that you could share on this? Maximum spacing of column, separators for casting each slab, max weight per each jack etc?

too expensive

Isn’t this the method used for a building in Bridgeport, CT, mid-1980s, that had a catastrophic failure? Resulted in two dozen fatalities?

Our system is much more reliable than the previously used systems because the locking is done by inserting wedges into the openings. Otherwise, you can visit our website and see the construction of the Russian business center Surgut Naftagas. The whole process of erecting six 10-story buildings was done in about 30 days.

Looks like a combination of basic modern jump form and 1950's lift slab technology that died an early death.

Gerald Duncan - So what do you know about the early 50s and 60s lift slab technology that died? That was some pretty incredible stuff to see in action, don't you think? I know of a couple of lift slab buildings in No CA that were condemned; not sure of exact reasons and what were remedies tried?

@@carlcampbell6827 Hi Carl, don't know much about lift slab. I teach construction in Australia and have only seen it in books, but it is never used here. From memory, the jobs in the books were in England and they mounted electric motors to hydraulic jacks that were positioned at the top of the columns. Those jacks rotated threaded high tensile steel bars (that were the full height of the column) and at the bottom end of the bar it ran through a large nut (for want of a better description) that was fixed/ welded to a steel plate that was cast into the slab. So a number of slabs are cast at ground level, then the top one is lifted by the twisting motion of the thread rod, then the cast in plates are welded to the columns, then repeat the process. There didn't' appear to be any bracing in the whole system so you have literally hundred of tonnes of concrete suspended in the air with next to nothing to stop it twisting and collapsing sideways in the event of some wind. That would have been my only concern, otherwise it seemed like quite a smart idea - eliminates all that suspended formwork for the slabs (which supposedly accounts for 1/3 cost of reinforced concrete structures).

They used this system in North Sydney back in the 1980's

THIS SYSTEM existed over 40 years ago in the United Kingdom . Same technique developed then by LIFT SLAB.
