- Another slab construction process great series video😁 In today's one you will see slab inspection step by step including rebar pre pour check and few good practices for a good civil engineer ⬇️⬇️
1. We will start to check if thermal break is installed correctly and as per drawing, as these might be the first to come and need some time to check. We are using a schock drawing in this case.
⬇️⬇️
2. Remember as at this point we should have all the drawings including rebar layouts and schedules. If we have a chance/time I would recommend to keep coming and checking the slab and if there are any additional to be install on the bottom mat we can now check/tick them off. If the reinforcement is complex and drawing not easy to read (remember most of drawings are meant to be read at A1 scale while on site most are printed A3) I also recommend to print separately bottom reinforcement and top reinforcement.
Please remember that on this type of slab there will be some shear reinforcement around the columns - shear links, or some shear rails might be used as well. These you need to be very careful as they might be issued on other drawing.
⬇️⬇️
3. Penetration, boxes - trimmer detail trimmer bars.
⬇️⬇️
4. Slab edge halfens check - if they in, if the right one used and if they installed at the right heights.
⬇️⬇️
5. Balcony stubs when installed, but now when all finished and edge shutter installed we have to check the position and level and if they actually in the level as well. Position - use templates, level of stubs - use laser level with 1mm tolerance the best, or EDM, and if stubs actually in the level - just a small spirit level will do.
⬇️⬇️
6.Next level columns starter bars, check if there are any new columns, or wall coming and check if there is enough splice for the next level.
⬇️⬇️
7. When we are all happy, we double check the cover now and tell the fixers where to rectify if needed - typically you will find the steel heigh in the columns area where additional steel is installed and fixers usually using the same height chairs, so they would have to bend them locally to provide minimum top steel cover in this case.
⬇️⬇️
8. When you all happy and going off the slab, please STOP!, turn around, open the GA drawing and have a last long look at the slab, counting the collars, boxes, balconies, look if the halfens are in and look if it really looks nice. I really want you to get that habit, even if you’re very busy, it’s max 5 minutes extra at this point and trust it’s worth it.
⬇️⬇️
Order the concrete, set the laser and let's go👍👍

This was an education honestly, learnt so much watching your vids,am a construction management graduate and site manager, but now doing an online course diploma in civil eng and structural Engineering being that I have been on site and big rc projects , this video explains so much about certain concepts I did not fully understand at some times.
Great job ! 👍
Thanks Andre!
Thanks. Another useful video as usual. Keep up the good work Greg.
Thank you! 👍👍
Amazing work mate 👍🏽
Thank you so much 😀
Another great video Greg 🔥🔥
Thank you!😁
Another Great Video!! 😊👍
Thank you! Cheers!👍👍
Good Job
Thanks!!
Great vid as always Gregg! Just did a pour there with 374 cast ins to soffit + 146 on slab edge. Of course they landed the mesh on the Saturday before I got a chance to mark 😢😷😴
Thanks Joseph! Yeah always like this, constant battle. Easy life is not for us, it's often like everyone is against us, but at the same time they wouldn't do much without us 😁
Hi Greg I hope you are doing great
Missing you and your perfect engineering videos
Am hungry for more videos please
Thanks
Hi! There will be more I promise, coming back to game soon 😁 Thank you for the comment, great to hear that. Next Saturday 💪
@@SITENG waiting for ya boss thanks 🙏 👌
👍👍👍
Stressful job anyway , I wish I choosed another profession back in the days . 😊
I don't blame you 😁
Thanks for the video. Do you have any knowledge or experience in setting out tunnels?
Hi! Unfortunately not much about the tunnels, I hope you will find what you are looking for 👍👍
Sir do you explain drawing very well
Thank you so much 😀
Great video. Can i know the name of the software you use to show and highlight the drawings?
Hi! It's Bluebeam Revu, great software, I have few vids about it on the channel 😁
@@SITENG noted thanks a lot. I watched many of your videos. It's very helpful and informative. Thank you for sharing.
Thank you👍👍 Happy to help 😁
Hi Greg, on the job I am on the edm screen shows a diffrent calibration level to the bubble level when I'm setting up. Do u know how to fix this? Which level should I follow in the meantime. I'm guessing the bubble?
If the EDM is good 'digital' level should be the one, as the bubble might need adjusting (small bolts there). When your resection is done you have to still two face check it (Hz and V). You received it like that? could someone hit it? TBH in general you shouldn't work with and ask for replacement stating the problem. Hope it helps 😁
@@SITENG yep recieved it like this, the asbuilts are showing good accuracy though so it seems OK for now.
@@bayernmunich1751 If you can change it, or at least do checks to make sure you good 😁
Hello Gregg hope you are doing well!
I have 2 questions:
1) shear links are mostly used for punching shear right? They are like stirrups but holding the top steel? Or they are just addition steel bars put diagonally in slab around columns?
2) whats half-ends? If thats how its written (english is not my 1st language sorry)
Also keep up the great work once im settled ill get you some coffee 😀
Hi Abdo!
1.Shear links are for punching shear and they play critical role in the structure. A shear failure in this case is usually catastrophic. They should be set vertically around the column (if needed).
2. Halfen - it's a company name really, but like in many cases ppl on site call like that all the fixing channels, they are typically used as elevation fixings, or as masonry support channels e.g. ancon channels. Halfens are sometimes used in lift shafts.
@@SITENG understood ! Thank you for the clarification 😊😊
@@Mr.Engineer93 No problem, happy to help 👍
Perhaps you should slow down a bit when explaining. Cheers
Hi! I am trying to keep the videos not too long and that's the reason. This one with others will complete a slab series where I hope watching all you will find the info. Anyway I will try to make it more like you say and maybe just do more videos but explaining better. Thank you for advice👍👍
@@SITENG thank you 🙏🏾
No problem 😁😁
