Your consultant has done a remarkable job . Columns size seems to according to load not over steel designed in slab also. Nice work... ... Have a cup of coffee ☕ enjoy your job..♥️♥️
What I found different in your column section drawings from ours is that the splicing of the rebars are shown just above the slab, while we avoid splicing in that region to satisfy ductility requirements. We tend to splice 50% of the bars in alternate floors at the centre of the column maintaining less spacing near the beam column junctions and the area just above the floor.
We always splice above slab. To be honest splicing in the middle sounds strange to me as in some columns there will be some moments acting there and normally you want to avoid splicing in these region. I have to check it as it's interesting for me, all Europe doing this way for sure and it's also easier for construction.
@@SITENG As per earthquake resistant details mentioned in our codes, we splice 50% bars only in a floor which holds true upto 20mm dia bar. For higher dia, we use couplers (only that it should not come in column-beam junction as it vulnerable to shear) to maintain rebar uniformity and reducing steel wastage. As for 100% lapping in a floor ( which I saw in your video) , rebars are never spliced at the same location. Distance between bars are kept at a distance not less than 1.3x development length.
@@SITENG To reduce the moment causing buckling, stirrups at the shear zone (near the slab supports)& lap location are densely spaced say at @100 c/c and in the middle @200 c/c.
I can't agree that you can reduce moment by using more stirrups. I agree that splicing all bars in one section is not the best, but as this is almost only compression at the bottom it's good and easy to construct. I am not sure about earthquake design, but germans do it and they splice at the bottom.
Im form China.As a country having 9.6million square kilometres,China has listed a table of the anti-seismic grades for the structure. It is related to building height, structural form and seismic level expect and so-on. The rebars in the columns must be connected away from the floor. But the rebars of shear wall is deffernt in different seismic grade. Low anti-sesmic grades can be connected above the floor.Maybe seismic level expect is different in Europe.
Hi Greg, Could you please explain more about rebar drawings, especially for the slab and beams? There are some small numbers written on the drawings with a little arrow, and its not clear to me. I appreciate that.
@@SITENG Yes, I looked at almost all of the videos; I couldn't find that. And sometimes in the slab drawings, there are little numbers in a bracket next to the bars! and I wonder what that is as well. Thank you.
Thanks Dav! Get on site and you'll get experience and any questions let me know :) My job now is full now, but any changes I will let know on my LinkedIn.
Hi Moon Thu! Position is on the drawing so if the bars are laid properly (distancing) all should be fine. Sometimes where there is no info and you can see on the drawing that bars are not to be laid evenly (eg. extra top bars - top column) you can always check the distance on the Autocad/ Bluebeam etc. If it's position in terms of bottom, top, sides cover I am checking these with tape measure off the decking.
@@SITENG do you use the survey nails and spray painting to set out the rebar? how do you know if the position you set out is correct? do you just use a tape measure?
Few times I used EDM to set a line which enabled fixers to measure (there was direction of rebar change as well), typically I don't set out for the rebar unless something is really unclear. Your tape measure should be well enough once your slab edges are correctly set out 😁
Hi Beano! That's true, I am on Hinkley point C now and can't record anything, will be trying to get permission. I understand why some don't allow, but I am here to explain and help people and if needed will change the site where I'll be able to do so 😁
I will do one soon, definitely! On site I mostly use them two and dependant what software client uses you will be using some platform for communications etc.
Hi! It's on the channel, construction site series, you can see there all you ask. If you will need more detail please let me know after watching the vids 😁

need to have a look again at the drawing TBH and will let you know
Very interesting 👍
Glad you think so!
Great video Greg.
I wish I could work with you to gain some experience on site
Thanks Dav! Get on site and you'll get experience and any questions let me know :)
My job now is full now, but any changes I will let know on my LinkedIn.
Another great video many thanks
Happy you like it Peter!!!
great job boss, another great video and please could you please do a pour in your next video and mayeb post pour thing in the video after. Thanks
Will do a couple vids small series on it soon :)
👏👏👏 keep it up incredible
Thank you Khalid! Will do!
Nice video Greg!
Thanks Jacek! Happy you like it :)
Nice.
Thank you!!
good job
Thank you! Cheers!
Thanks brother
You're welcome! Thanks for comment Jamie :)
nice video thank you
Thanks for comment doctor ;)
Could you upload videos when they marking column on the slab, are they using then local resection?
Hi Gamer! I will do that soon, next video marking decking and following will be columns :)
👍👍👍
Thanks Lidia :)
Great video Greg very informative
Thanks 👍

Hello Sir. Your channel is very benefit for us. How can I get contact with you ?
Hi! Please write on LinkedIn 😁
How do you check the position of rebar?

Most sites for Tier 1 contractors don’t allow mobile phone, filming, etc. I wonder, do you get permission from the PC to film?
Hi Beano! That's true, I am on Hinkley point C now and can't record anything, will be trying to get permission. I understand why some don't allow, but I am here to explain and help people and if needed will change the site where I'll be able to do so 😁
Hello sir, which software are you using to come up with the drawings
Hi Bruce! I am using Bluebeam Revu. It's great :)
Come up with a video in the way you implement bluebeam at your site. Do you use any other softwares apart from AutoCad and Bluebeam?
I will do one soon, definitely! On site I mostly use them two and dependant what software client uses you will be using some platform for communications etc.
Sir, these are too big to digest.. Start from scratch. Like column, beam.. Less area.. Please🙏
