- How it's done. What's the construction procedure. What do you need to know during pile cap construction process.
Construction site #05 "PILE CAPS". In today's video I will show you step by step the pile cap construction process. You will see whole process of construction starting for excavation - digging for which you have to set a laser as per drawing including in this case extra 100mm for cell core and around 50mm for blinding - 150mm below soffit = 225mm below pile cut off level (75mm pile projection). After pile cropping pile integrity test has to be taken to confirm good pile condition and then blinding - 50mm layer of concrete and cell core installation (heave board) on top. When ready like this it's time for setting out the lines and double check the levels. Site engineer job is to keep checking all the time and making sure everything is as per drawings and in this case the pile cap information is collated from few trades - drawings: drainage, foundation layout, RC drawings, crane installation drawings and lightning protection, so as you can see always get all information about the job you're doing 😁 Before pour last checks have to be done with the client - rebar, crane anchor position, started bars etc and then green light for concrete is given 👍👍👍

Awesome video. I'm doing a fourth year construction management class - In my project I have to interpret sketches for bored piles and a pile cap, and produce cost estimates - this video made it super easy. Cheers Greg!!!
Great to hear that Jack 👊 Thanks for the comment 👍
@@SITENG No worries. Actually I had a couple of questions. I'm planning a long retaining wall supported by deep bored piles under a pile cap. The plan is to drill & pour the odd piles, then turn back at the end and do the even piles. How long after pouring should I crop? Would it be better to do the pile cap pour all in one go or in segments? How long can blinding remain before pouring should occur? Cheers!
Hi Greg, Everything about this video is simply perfect. Thank you.
Keep doing the great work!!!
Thanks, will do!
Wow, that's impressive. Your are, way above me. Keep uploading videos
Thank you wiese680, I will do :)
Thank you Greg!!! This is really useful for me to understand construction in my work
Great to hear that Stephanie 😁 👍👍👍
These videos are excellent keep them coming!!
Thanks Shane👍👍👍 Comments like yours keep me going 😁
This is quite helpful, keep it up!
Thank you Bilal! I will do :)
Agreee - superb video, very informational!
Thank you 👍👍👍
Great video mate
I’m a fixer looking to get into engineering loving these videos
Great! Happy you like the vids 😁I was a fixer too when I was doing my school 👍👍
Very good channel engineer!
Thanks!
Impressionante a robustez das fundações e ferragens. Parabéns. 🇧🇷
Hi, don't speak Portugese, but I hope you liked the vid 😁
Good construction Greg. Conrac
Thanks 👍
wow great job
Thanks Omar! Happy to hear that :)
Great video! I notice you have used benched excavation as the excavation protection methodology. Why is that, over regular sloped?
We're stepping the excavation to make it safe Jordan. This way we don't need to use extra Temporary Works.
Greg,
Superb video of the construction of the pile cap.
Excellent presentation and very good back up commentary.
What is the drainage pipe for in the pile cap?
Brilliant video. Lets have more of the same.
Thank you Asim! Very happy to have you here :)
Nice illustration
Very informative video.
Thank you! Happy you enjoyed it Jake 😀
Great videos bro
Thank you!
Quite cool and thanks for the video, similar steps as we did at hk. But we won’t backfill before casting the conc. We will make the formwork and pour conc first before we backfill it. Just curious about is uk common to do sand replacement test SRT for backfilling?
Hi! No tests in this case, just a ground backfill. Later the heave board was used under the slab to allow for some ground volume changes.
Good to see tidy site from JRL at intro
Yeah, always nice and tidy work done by guys I must say 😁😁
good man thanks.
Thanks Jamie :)
Thanks For Teaching Sir
No problem, happy to help😁 Thanks for commenting 👍👍
Hi Greg, thank you very much for the videos! It is really helpful!
I have question for you. At the first part of the video we can see a guy doing an integrity test.
What to do if there is discontinuities in the concrete?
Thanks
Hi Viktor! In our case this have to be reported to the designer and it's his call. He might redesign the pilecap, add a pile, or maybe even approve it. It's not a site decision.
In the past we have hand to bridge the failed pile with a reinforced concrete beam which allows the loads to be distributed, provided the other piles have the capacity to take the additional loadings of course
Good job Go ahead ❤
Thanks
Thanks a lot boss
No problem! Thanks for comment!
Amazing
Thank you! Cheers!
Hi can you please upload a video on how to calculate volume and area using ts15/16 please. Such as stockpiles
Hi Khalid! Unfortunately not now as I have planned other vids for now, but will here finally:)
Thanks sir 👍
Most welcome
good job
Thank you! Cheers!
thank you for the vlog
what are the "lads " you mentioned in 2:01
guys, workers
good job, pile breaker.
Yeah, makes lives easier 😁
What about PLT? I didn't see you do that, or it was done outside the the video.
Weldone job.
Construction or nothing else, it's my joyful work with passion.
Hi Kwasu! Not sure what do you mean by PLT and PIT? I have to watch again, but I pretty sure everything is on the video, except pour I think.
Im also curious about it. He maybe said for the plate load test
Hi Greg, May I ask a question what is the purpose we need to erect those U shape steel bars on the pile caps
Hi Alson! I don't know why but I can see your comment now, but it's from 2 weeks. You mean U-bars around the cap? These are needed to provide correct anchorage-connection for bottom and the top of steel, also they're needed from construction reasons as this way the cage can be constructed - let me know if you meant these ones 😁
I want her whatsapp number.
What mix and slump do you use for the blinding?
Whatever I have 😉 the cheapest you can get, best some pour leftover 😁
♥️👍👍👌👌👌
Hi Greg, what’s your preferred method for a marker when setting out piles?
I used pins with mushroom cap on top and spray (like on the vids). Using Stakeout program for it - info taken from pile schedule drawing
Weldone job. But I didn't heard you talk about PLT, you only did PIT. isn't PLT necessarily?
Thank you Kwasu😁 As in before comment please let me know what do you mean by that 👍👍👍
👍
Thank you!!
May i ask what are those material that u use on that black pile cap formwork? Thanks
Corrugated beam form sheets
@@SITENG thank you so much
@@sanggabuanasatria3315 no problem, happy to help
Can you show us how the survey report should look like? Cheers.
Hi Mihai! I will try to get it available for you guys to download, but you need to give me some time :)
Please make videos how calculate concrete of pile caps
Hi Ibrahim! Check my concrete video please :)
Hi 👋 brother
I m new subscriber from India.
How are you.
Hi Ravi! Great to have you here, how are you ?
@@SITENG Fine brother.
@@ravishankar-rp2wx Good!
Hello sir pile and pile cap drawings. How to read
Tell me please sir
Look on my other videos - how to read the drawings 😁
Integrity test🤔 so what happens if it has a crack?
Hi! To be honest never had situation like this, but this has to be assessed by the designer and in best case will get a green light and in worse case scenario pile to be redone/extra pile or piles installed next to it to make sure the load will be properly distributed to the ground.
@@SITENG 😁 had that in mind that it would have to be redone. I just thought you could be having another remedy.
How much dia this 25mm or 32 mm
That's the diameter 25 and 32, if it comes to area it'll be 4.91cm2 and 8.04 respectively
Hello may i know why the concrete got cracked at 2:26
Maybe during the cropping, looks like the rebar was hit/bend thus causing the crack. It sometimes happen, especially when the foam is not perfect and you struggle with releasing the concrete from the rebar. Remember that at this point all these piles are checked for integrity to make sure all's good :)
@@SITENG Thank you!
@@holygate527 Always happy to help :)
Sir I am civil engineer , may I come in UK for civil engineering job
Might not be easy, do you have visa etc?
Sir how can I apply as a Site engineer in Uk
Hi! You will need some kind of permit to work then NI number and CSCS card. Contacting people on LinkedIn, looking for work on sites like cv-library and indeed and if you are in UK going from site to site and ask for work 👍
Can I opportunity to do job with you in abroad I'm from India I already have 4 years experience in pile,pilecaps, pier ,piercaps but waiting for opportunity
Can u lead me to achieve my ambition to work in abroad
Hi pushpak! I am afraid it's not possible especially now. I am doing different package and it's small company so not a chance to bring anyone. Keep looking for something and if I can help somehow I will!
Where r u from dear
Hi Kumar! Born in Poland live in UK :)
@@SITENG what is your profession dear
@@SITENG civil engineering
Civil Engineer, working currently as a project/senior engineer.
@@SITENG good
Laying your work tablet on the ground with no case or anything is wild! Money must be nice for that company. Could be better if they didn’t have to buy a new one every year because you keep laying that one in the dirt.
Agree the way people trating equipment on site is often terrible as they don’t realise how much it costs, in this case the controller is mine and let me do whatever I want, all the best!
