I work for Keller too!!

[@SITENG]

They did a great job there 💪

[@TheMrasimqureshi]

Super video Greg. Great one. What is the difference between the Integrity Pile Test and the Pile Test with the yellow steel bar in it. What happens if the pile fail the Integrity Test. Who orders the concrete for the pile and who checks the quality and specification of the concrete used for the piles. Very good video which is filmed brilliantly as the HD quality is superb. Excellent.

[@SITENG]

Hi Asim! Bearing capacity test check actual pile capacity to check the discrepancy between reality and design - pile is kept under load and movement is checked. Integrity test checks if the pile has any irregularities in the concrete structure (cracks etc).

[@mrmalab8937]

The piling company orders the concrete and they do check the quality of the concrete by taking samples typically cubes. hope I answered the concrete part.

[@abdulwahab6755]

Good informative video. Safety information need to be please.

[@SITENG]

Thank you 👍👍

[@indranilbhowmick8459]

Did u do lateral dynamic load test of working piles. Want to know about that test

[@SITENG]

no, sorry 😁

[@PandapandaP]

thanks for the video, how to calculate survey record of the first or final casing and complete the excel report for the survey job?

[@SITENG]

not really sure what exactly do you want to know, but someone should show you what they do within the business

[@mohsinmoroney5824]

Hi I have been out of practice with the total station for while. Could you put a video up on how to setup and stakeout on site please

[@SITENG]

Hi! Check my setting out playlist, everything is there 😁😁

[@samadheidari8880]

Hi Seting, Thank you for your information. Can you specify the standard method for pile test (bearing capacity)? ASTM or any other references. Thanks

[@SITENG]

well, standard method is to load the pile and check how it reacts under :)

[@enriquelaya]

Can you please comment what is the design load for this 75 ft deep auger pile of about 20 in diameter? Is it designed on both skin friction and tip load ? What was the mesured spt (or cpt) at 75 ft depth while geotechnical surveying? Many thanks

[@SITENG]

Not really as I wasn't involved in design and there was a piling contractor. I am nearly sure all these have to be skin friction in this conditions. Can't tell you about the measurements you ask, sorry

[@squallconstruction]

What determines the depth that you drill? is it based on the load bearing or its really the base at which you touch hard rock?

[@SITENG]

this is design and depending on the pile type - some yes, have to reach a good layer, but in most cases this is the friction on the pile surface which is needed to hold the load

[@CalumKemptonMusic]

how are you checking verticality and position? We are governed by SPERW 3rd edition: Geometric Tolerances: top of steel: -50mm/+150mm position: = +-75mm verticality 1:75 I suggest total station using cogo arc calculation on the hollow core of the auger. I thought these QA would have been priced in, but they are not. I will be running this past my company next week, but I think there are commercial blockages even though we are responsible for adhering to the piling specification. I did not see anyone doing total station surveys on this video. Checking bored piles with casings verticality and position are a lot more straight forward.

[@SITENG]

once it's marked is the rig driver to make sure it goes straight etc. Top of steel is related to the platform level and tolerances you have are enough to go like this although on one job I actually measured the level to tell guys how much to plunge the cage ( that was due to the state of the mat really) Then you do the as built survey on the pile position. The rig creates a pile report about the pile and then the pile integrity test is done on the cut off level and that's about it :)

[@CalumKemptonMusic]

​@@SITENG There is a inclinometer on the rig, but it only informs you of the verticality or levelness of the rig. The auger is made of 3 sections and generally can't be taken out of the bore once it starts boring. T he piles are 10-12m deep with a 600mm diameter. Our PPL is 67.000m. The mat is a up and down at places. To be cost efficient, we are using the existing tarmac as the piling platform. There are a couple of softspots that have been dug 630mm below the PPL and backfilled with 6F2. I set up the control network for the job and we are setting all of the cages with a laser level. Our rig has it's own software for measuring certain parameters and the workforce have paperwork they fill in also. As I said we are governed by the ICE SPERW standard which means that the piles should be of a verticality of 1:75 - circa 160mm deviation in the horizontal axis at the toe of the pile. The position is to be within 75mm and the steel is to be -50mm/+150mm.

[@fahidaismail6904]

How long does it take for the concrete to set?

[@SITENG]

Depends on concrete really, but 24h typically, when piling it might be less, all dependant on the mix used

[@joshua201290]

Why the different colour rebar some is brown other looks to be galvanised?

[@SITENG]

Hi Joshua! They all the same, there are not galvanised as I remember, they only used in some cases, very rarely. The difference you see is the rusty one against 'fresh' ones. Even after few days rebar will start changing colour as the rust starting to get it 😁

[@deepaksaichowdary]

what is RIG works, which you mentioned in video?

[@SITENG]

It's a piling rig - a piling machine, so probably the works it's doing - drilling and concrete

[@aliyarbi8283]

Hi 🙋 i really liked your video, i know that KELLER is really best company in this work, i would like to work there future as a Piling Rig oparator, best wishes from Turkey 🙂

[@SITENG]

Happy you like the vid! Yeah, Keller is huge and have great projects. Wish you all the best, chase your dreams and see you in the future on some great project 😁😁

[@tonnag7588]

Hi, Could you be more specific please in setting out by showing how you use EDM. how you stake points, survey land, as build, programmes you using on total station, mark points on the site by spray, drawing, etc. this will be more useful for those who wants to become Setting out Engineer. Thank you

[@SITENG]

Hi Rido! You can see EDM in Setting out series, unfortunately it's not easy to record while doing setting out. I was thinking about installing go pro on my hard hat, but it won't work on my site. I will try my best to show this though and in my next videos you will see more 'in action' vids.

[@tonnag7588]

@@SITENGThank you👍

[@yavuzcinar6487]

Hi Greg, do they use tremie during pouring concrete down?

[@SITENG]

Hi Yavuz! These were CFA piles, so simultaneously with the auger withdrawal the concrete is being poured. I am showing the 'drill' on the video where you can see how it works.

[@oluwakayodefarotade3760]

I have an ongoing site the land is just being reclaimed in a mangrove swamp area piling is needed but it's my first piling job can u help with an extensive video

Pretty sure they were 450, but can’t remember now, some 600

[@ar.piyushsingla8170]

How many piles can be built in one day? Lets say pile has 1’ dia and 20’ deep. Please answer 🙏🏻

[@SITENG]

Not sure now, but depends on many things, logistics mainly, how many rigs, ground condition etc. Will ask and let tou know - 1m D 20m deep right? 1m are quite big ones TBH

[@khalidhashemi1181]

hi Greg had a question, I am currently setting out piles and the pins we have is 600MM, it is really hard to get the pins as low as the ones shown in your video. How do you often do it?

[@SITENG]

Hi Khalid! you need smaller pins, cut yours in 3, 200mm is well enough - and you will save some steel 😉. The pins don't have to be long to keep the position for piles. I was doing piles few times, but last time maybe 3 years ago 😁

[@khalidhashemi1181]

@@SITENG great thanks for replying. Also what is often the pile tolerance? Thanks Greg appreciate it

[@SITENG]

This depends on the project really, but it's sometimes even 75mm, so quite a lot :)

[@MoBH88]

Thanks for the video, I am a BEng civil engineer with 4 years design experience, how can I move to site without any site experience or setting out experience? Most job offers put me down as they always require some setting out experience. Thanks again brother.

[@SITENG]

Hi Mohamed! You have to try get a job as an assistant/junior engineer first and spend some time on site. In your case it's not going to be long as you have design experience and a degree, so it's only a matter of learning a bit of setting out and see how the work on site is looking. Once you will have even little of site experience look for site engineer position.
