hi guys and welcome back to SITENG today is the second video covering the pile caps
and in today's video i'm going to show you the rebar drawing but also remind you why
is it so critical to have all information all the time with you while you're doing the pile
caps and at the end of the video having look at the piling layout and piling schedule we're
gonna we're gonna double check if our calculation for the pile caps are right so hey guys let's go
so guys before i'm going to go to rebar i just want to show you
all the information i gathered from all these drawings you could see on the last video and
i want to tell you why it is so important to keep all them together and it is so critical to
know what's below you what's at the level that we are working and what's above us as you can find
a different information there and very useful information and actually this drawing showing
even better to the last one what i mean actually you can see here the the the level we working
at uh that's the that's the working level i called it this way so this is our pile cups here
our drainage which we have to do as we go in with the pile cups and the rebar drawing which
i'm going to show you actually later as well but what i mean to know what's what happened before
it's the piling layout this pile is already there and we're going to be looking for them we're going
to be cropping the piles and prepare them for the pile caps and actually this one we can use as well
to compare our calculations for the cut-off level as on the piling schedule there will be a cut-off
level for the piles this is actually only for us to double check this as as we're going to be
doing the pile cups this is already done so we're going to be cropping the piles to make sure our
pile cup is going to be done as per the detailed drawing and as per ga drawing but this is this
is another double check for us and it's worth to check it actually that's why i put it here as a
level below and working level as i said we got all this drainage already bar all the stuff and level
above you can see the level above it's a basement slab and this is the place where we actually got
the information about the columns and about the columns setting out and that's why we need to look
uh in into the future really so so we're going to know what's happening and only then we are we are
hundred percent sure we got all the information and we are good to go and we never gonna make
any mistake so uh guys uh i got the rc detail for the pilecaps here and i'm gonna have a quick look
and as i said on the last video i'm gonna let you download all these things so you can have
a look uh yourself as well and if you got any questions just you're going to come back to me but
i'm going to have a look at this two pilers here pc2 2.7 by 9 1400 deep so this is actually okay
so it's very simple here you can see it's going to be 32 mm bars what we got we got the 16 mil U- bar
on the sides so this is very easy and that will be much better if you want to if you if you're
going to download this and you're going to have a look yourself so that's another pick up here
but what i want to show you here is the most important information and the most important
thing why we're going to be doing the pile cups is the column starters as especially when while we're
going to be ordering the steel and we're going to be doing the columns we need to make sure the
steel ford is going to come with the starter bars and we've uh drainage so uh i just found it here
you can have a look this is the information here for column starter details refer basement to first
floor so that's again what i said but we working at this level here we're doing the pile cap
but then look into the future guys look into the basement slab as there will be information which
we actually need now at this moment as later there's no chance we're going to install any
starter bars and believe me guys mistakes like this happen as you need to remember that rc rc
frames this is a very busy environment and it's not that easy to be well organized and that's
why you need all this information like i'm showing here just just to avoid any mistakes really we got
the pile caps drawing here uh as i said they're really simple but we're going to be now looking
for the columns and i got these drawings here i'm going to show you this is actually the basement
to first floor column so that's what i'm saying basement no one says about the pile caps here but
you need to have these starters while we're going to be doing the pile cups so this is a sheet one
the reason i'm going to show in this sheet one is because there is a layout for the columns here and
that's actually the area i was looking for is these four pile cups here and as you can see we
got column 77 and column 75 here and we're gonna have a closer look at these columns these are not
marked as you can see here this is block a and a5 so these two probably you're going to find in
other drawing covering the block a1 and a2 so guys i'm looking for the for the column starters for
c75 and c77 and then we're going to have a quick look at the basement drawing and just do the last
double check if there is no discrepancy between the drawings and if there is no mistake done
by the designer so i'm going to go now looking for a column 7 75 so these are these two columns here
and we guys at this level we are only interested in this bit here uh because we're going from the
pile cup we need the starter bar so as you can see here we're going to have 8 20 mil bars here l bars
we're gonna also need four links uh number one and four links number
two as well to install them in the pile cup to installing links in the pile cup that's that's
another thing guys i'm gonna tell a little bit more about this when i'm gonna be doing the
structure series as these are not always needed to be honest but as i said i'm going to try to cover
it in the future but we definitely need them 20 mil bars and column 77 it's the same story
we need to adjust this beat to make sure we're going to have a starter bars at the same time
we're gonna bring the steel for the pile caps so i'm just gonna take this bit here with us
for that drawing just copy this and i'm gonna put in here so that'll be this column and well we can
have a look again we just compare this uh with the basement slab and we want to make sure if
the information is correct so uh i actually took this from the from the basement slab drawing here
column a and column b there's two types here uh i'll just show you in a minute as well but it's
400 by one meter column and this is correct here on the on the steel drawing and this 400 by 400
column is here c77 which is right as well so i'll just quickly go here and show you the basement
slab drawing here confirming that this is a and b so you can see here this is column a and column
b so that's right the dimensions are okay and uh actually the rebar drawing is okay but what else
we need for the rebar drawing as you remember probably we're gonna need the rebar schedule as
well and i got the schedules here and uh obviously we're gonna need first for the pile caps once
we're gonna be ordering the pile caps and as you remember we're doing here i'm showing you
the pc2 and the other one i'm showing the pc to a so that's going to be all this this is pc2a again
so we're going to need this steel for these pile caps and as i said when when you download these
things you can go yourself through all this information and if you got any questions just
come back to me and i'm going to explain you more as i don't want to take too much time now covering
all this information about the rebar so i'm going to come back here guys we got all the information
about the pile caps we got top of the concrete we got the drainage we got the reinforcement we
know what's going to happen on the basement slab and we know as well what was happening before
and the last exercise maybe for this video we're going to double check if this cut-off level is
actually okay so uh just to quickly show you see them uh this is the same beat of the drawing so
37 and 38 gonna be for the pc2 and the 39 40 41 gonna be for pc3 but we're gonna go only for pc2
here which is the 1400 deep and we got top here for the pile cap so so that's gonna be guys our
42 715 minus 1400 which is a depth of the pile cup and plus 75 mil projections for the pile
and that should equal 41 390. so let's have a look quickly guys uh 42715 as i said minus 1400
which is the depth of the pile cup and then plus 75 mil and that's exactly what we got 40 41 390
so that's accurate now 41 390 we checked it so the piling schedule is okay actually and maybe
i should say our calculations are all right as well and this is our double check for the cut
off level we are sure now at this time we're going to crop these files to 41 to 90 whatever happens
and uh we good to go and that's actually all we can do when we're gonna be doing the pile caps as
uh as i said we got all the information now guys and this is very important i got the drawing here
i took information from all these drawings here so guys you need to remember when we're going to be
doing the pile caps you need all the information i'm going to repeat it again we gotta we have a
pile cup layout here we got a drainage drawing as well we got basement slab and then we got
the rebar drawing well we're going to see actually in this case basement to
first floor columns and we're going to take the starters from these drawings we found them columns
here whatever columns we're going to be looking for we have to look for them obviously through
the drawings covering all these buildings here and there is many sheets for each building so that's a
lot of looking for as well and then uh obviously we got the pile cap rc detail drawing as well
and with the schedule and not gonna be same for the columns maybe guys i just gonna quickly come
back to these columns we had number 75 and we're going to be looking for this here so uh i'm just
quickly go to the schedule and just to mark up for us what we are looking for it was column 75
so that's the column here but the most important thing guys we only need the starter bar so that's
going to be what we need we need a number one two three at this level and all the rest gonna be
ordered in the future when we're gonna be doing the basement to the ground floor slab and then
another one from the from the ground floor slab to the first floor slab so that's that's a little bit
of playing here and this is very easy to make a mistake but but once you're doing the basic
engineering uh stuff in terms of setting out and maybe the quality checks you don't need you don't
need these things and i'll obviously cover this i'm gonna i'm gonna do a separate video about
the call-offs and what you have to look for while you're going to be doing them so guys
i think it will be all in today's video and uh as as i said before in the last video i changed a
little bit the way i'm i'm showing this and please leave me the comments let me know if you like the
way i think once i'm gonna let you download the thing so you can have a look yourself i i think
the way i'm showing this now is much better as well and just guys as you can see on this
drawings i collected all the information from from plenty other drawings and that's how you should
be looking and that's our engineering job just to combine all the drawings take all the information
we can get maybe even like this put them on the on the one drawing and also we're going to create
like like a working drawing what i was showing during the cupping beam so that's that's how we're
working so yeah thank you again for watching and uh please don't forget to subscribe to my channel
and leave the comments guys if you want to know more just ask me questions i always reply to them
as soon as possible and also guys let me know if you like the way i'm showing these drawings
now as i'm gonna probably keep it this way so yeah guys thank you again and see you next time
