How to construct a PILE CAP. Step by step guide & pile integrity test

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 👍👍👍

Great to hear that Jack 👊 Thanks for the comment 👍

[@jackanderson9896]

@@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!

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?

[@SITENG]

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.

[@Pandeedar]

good job

[@SITENG]

Thank you! Cheers!

[@Jordan-dw7bp]

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.

[@vctr196]

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

[@SITENG]

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.

[@Construction_insider]

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

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.

Whatever I have 😉 the cheapest you can get, best some pour leftover 😁

[@alsonsim863]

Hi Greg, May I ask a question what is the purpose we need to erect those U shape steel bars on the pile caps

[@SITENG]

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 😁

[@yahiamessaoudi5413]

I want her whatsapp number.

[@kwasuzitung3321]

Weldone job. But I didn't heard you talk about PLT, you only did PIT. isn't PLT necessarily?

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

[@basilagula9977]

Integrity test🤔 so what happens if it has a crack?

[@SITENG]

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.

[@basilagula9977]

@@SITENG 😁 had that in mind that it would have to be redone. I just thought you could be having another remedy.

[@holygate527]

Hello may i know why the concrete got cracked at 2:26

[@SITENG]

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 :)
