This video is a huge help. thank you. Just a quick question.. are the jack rods encased into the concrete just like the reinforcement, or no? any help is appreciated :))
Interesting video! I’ve ridden 50+ slips here in the USA and Canada. Same method, but very different equipment from what you do are using for elevator cores. Who do you rent the slip yokes, jacks, etc from?
That job the company owns it (JRL Group). They prepare everything off site and assembly is really quick without 'long' carpentry works. How's working in Canada and US ?
@@SITENG we use a company called Scanada for jacking equipment and build wood forms on site. I enjoy working across North America. Lots of great people working together!
Hello dear, Do you have any video for the construction of mass concrete foundation for thickness of 5 meters and above. If you have please let me know and how could contact you. would be appreciated.
Greg, how are you guys transferring datum’s up your cores for the slip? I’ve just been using steel tape for the jump form I’m on at the moment, only 7 levels so not massive. But interested to see how you do it for much taller elements. Seen some guys say these use vertical lazers.
Hi Joseph! It's a steel tape too, but also the lasers. Slipforms on the video using the laser and shows the level all the time. I did not the ones with the laser myself, but has to be nice 😁
Hi Abiton! the easiest way I would say it's 'small wall' few hundred mm high eg.150mm. It is used for example to 'hold' the screed and poured to the finish level height. Also used to sit something on top (windows etc) where you need structural concrete - in this case called plinths, plinth wall as well.
Can't remember now TBH, but in terms of height is was often ar. 2m - I don't have the walls section area to tell you, but these were small slips. I worked before on Nova slip and couple of weeks on 100BG (the biggest one that time 😁)before I took over the basement. This one wasn't operating 24h, but there are slips like that 😁
@@SITENG and we'll need various main rebar templates or our surveying team will be exhausted to mark those coupler positions . meaning , another lots of sheet . oh shiiit .....
Hi! It's there on the vid. Kwikastip is used (continuity strip/contibar - pull out bars). After the decking is ready this is first job to do - pull out the bars + do the final check if anything is missing as there might be some drill&fix needed. Then pull out bars are spliced with slab rebar. Rebar is connected and the small recess after taking rebar out in the kwikastrip quarantees good connection in terms of shear force.
Typically there is a good steel tape inside the core to refer to it. If you mean the tape measure that's the one you'll be using almost all the time as you will be measuring off your datums - marks on the rebar etc. Slipform is a tape measure job and it's well enough. BTW tape measure is our best friend and I have impression people want to measure every simple thing using the EDM - whatever can be checked/measured with the tape should be done with the tape :)
I don't think there are horizontal ones. You would just pour the walls and move on ( could be done on some rail system). That's why slipform is a great idea as there are no horizontal elements taking the loads 😁
@@نورالايمان-ف5غ7و check Peri solutions, they have some shutters on rails running horizontally. Still it will never work that fast , hope you will find something, or convince them to use maybe precast elements to construct the tunnel
Great video Greg and well explained 👏 👍
Thanks Jamie! Happy you like it!
Hi greg, keep up the great work. You have helped me understand the basics of the key skills of civil engineering. Keep it up.
Thanks Jp! Happy to help :) Will be uploading the vids ones I sort my YT access. I am on holiday now and have difficulties. Lucky I can comment :)
Thank you for sharing.
My pleasure! Thank you for the comment Tom!

Happy to help. Yes, they are 👍
Excellent video! Looking forward to your next video with interview of engineers.
Thanks Bhernonche! I did not 'get them' when I was there, but definitely will try to speak with them, even if on line.

Good vlog , I worked once on the slipforms , not for me , I don’t like heights and tight places :)
Thanks Eric! Yeah slipform is very specific job and not for everyone. I don't like it too, I couldn't work all the time with slipforms.
Hi sir good day can i apply at slipform technician .. thank you
You have look on LinkedIn for it, or a cv-library etc
Great video mate. Loads of information. Cheers
Thanks 👍
100% perfect video
Thank you Kevin!
How you control verticallity?
this one has a lasers set and show the position all the time. It's a slipform driver's job really to keep it right and keep correcting as we go
nice to see greg
Thanks Chris!
awsum one greg
Thank you! happy you like it😁
Great Video 😀
Thank you Survey Book :)
Good work sir
Thanks
Good work
Thank you so much 😀
Another great video 😊 very interesting 😊👍

Hi Greg , roughly how many cubic metres gets poured daily and is this a 24hr operation ? Thanks

@@SITENG Thank you for answering, great informative videos
@@kojo8770 Thanks! Happy you like the vids😁
tell me mate how you join the main rebar of the collector beams to the core wall . thank you
no beams on this one, but that would be couplers mate

sir i have knowledge about slipform and i am a civil engineer so i will get job
look for it, there are jobs for slipform engineers, so there shouldn't be a problem
How slab reinforcement joined with slip form wall ??

You're welcome 😁
Helo my friend
Hello 👍
It is me on the video 🤔
Minutes 03:34
Why did you break up with JRL?
I might be back soon, who knows 😁
If i have a civil DAE, can i get a job in england
You will need a work permit in UK, or a sponsorship from a UK company
Can you please send me the name of laser used in her for slip form or link please
Hi! I don't have it, sorry, you have to dig for it on net 100% you'll find it. If not come back to me :)

How to transfer datums?
Use a line laser
@@SITENG on the rebar? But we will loose many millimeters let's say if we have 50 stories
@@SITENG i know someone are transferring with the tape measure, but is it accurate?
on the climbing tube, then whatever you need on the rebar - using electric tape.
Typically there is a good steel tape inside the core to refer to it.

design of horizontal slip form????
?? did I say horizontal?

Finishing is not good coming
what do you mean by that?
@@SITENG sir i am also slipform technician but wall finishing not coming good
Sometimes concrete stick on panel so effect on wall finishing
@@govindvekariya8627 yeah wall finish is not the best, but fortunately it's not that important there
