hi guys and welcome back to SITENG uh in today's video i'm going to show you the ground floor slab
and i'm going to show you the decking how they how they install in the deck in here on this side and
then later i'm going to show you the probably i'm going to show the beat of the slap already
and then i'll show you how they fixing the steel and then probably the poor as well so yeah let's
go
so guys as you can see here a guy is using the big tables uh it's only four legs it's
very good system you see there's a big big uh surface covered with the one table
they got tables obviously they have to be some traditional decking i mean traditional the the
dockers the prairie dockers like this one so that'll be normally you're probably going to
see this but there's many types of decking when i'm going to be covering this uh in the drawing
section we we're going to go through the most used decking types here in uk the guys here using
as well the sky deck you won't see it here but i show you some photos
so that's how it looking the most important thing guys after after we pour the columns which you
could see on the last video and the walls you what you want to do you want to mark the datums
on the columns and the more the more you're going to mark the better for you the easier going to be
to set the laser later for the soffit of the slab so what i'm doing i always set the laser
and once you got to the soffit level i actually write on the column i do like a small table with
the soffit of the slab and all that stuff once if you got the step in the slab what i do like here
obviously this is uh this is the brushed finish so you you don't really want to spray on this but if
it's not i just mark the lines where the steps are i mark the lines on the basement slab so the chip
is the chip is got the drawing but it's always easier for them to see where the step gonna be
and once they form this one on top of it on the ground for which i'm gonna show you in a minute
uh you're gonna see that the actual step have to be created so to get the step on top of the slab
you need to do the decking little bit further uh while doing the decking so that's the thing you
need to you need to look at as decking have to always pass the step so you can form the
from the step i'll try to explain maybe more in the drawing section when you're going to see the
lines and how we're going to set the deck so yeah it's very simple here you see the legs so the guy
is going with this they got some infills there and uh oh that's the laser for the sleep form so
the most important thing as i said you set the datums and the set the level and the level has
to be right so what i usually do i set the laser five mil above the soffit of the slab that's it
no more than that that's well enough and then when before pouring you're gonna be checking the slap
level if it's a little bit too high or something you can still drop it's always easier to drop it
then uh raise it so about five mil it's well enough you can leave it because the guy's got
the drawings here that's the steel drawing for this uh that's the deck you know that's the
shutters for the columns so i got everything here i believe this is the mark yeah they got the pores
different colors they denotes the the pours and this uh oh yeah you can see here port number two b
four number two a four number one and that's what they use here so they got the drawings
they're ready for it everything is good but you still as an engineer you need to keep
an eye on what they're doing all the time all the time just just have a look ask if they need
anything else on if you can help somehow and yeah everything should be fine okay let's go to the top
so that's the guys how it's looking from the dog you see uh we got the quickest strip now open
uh from the core uh we got the starter slab starters from the capping beam here as well
the steel is here you can see the red ones there is the Hilti collars
that's the fire collars uh where the penetration gonna be the later pipes gonna be run through them
so you see the fixtures are installing uh the bottom mud is already there uh you see that
step there i told you that's the tape here on top so you need to make sure you you get this ready
when they're gonna be when they deck in really you got these columns here see they are around 20 mil
above the soffit of the slab which is our decking level now and the chairs are there they started
installing the top steel so everything looking all right everything good uh i just show you
here on the right hand side there already polar pour a little bit so yeah let's go
yes you can see this is uh that's the thing they're gonna be injecting for the waterproofing
so that was the connection with that the liner wall you can see it here the rascal product i
promise i'm gonna have a little bit more in the drawing section that's the flat poor the guys are
laid still here so they they got the they don't have a big distance just for the steel
there's a step here you see the line mark for the step now on top to create it some Hilti
collars lying there so i think that would be all to be honest it's all going to be same now after
we pull the slab here we're going to be line marking lines for the columns and then later
pull the columns and then again and again so that's only going to get you to this step while
all the floors actually are the same and maybe the Hilti collars position gonna change a little
bit so that's what i call that copy paste copy paste so it's not that interesting in terms of
engineering but always good to do at least one two jobs like that but the most complicated stuff and
most interesting stuff plays in the ground and then later in the grand floor slap as there's
plenty steps as you see that slab is quite big it's 600 uh maybe this side maybe a bit more i'll
double check it on the drawing that one looks like 350 maybe 400 so the big slab always many steps
and uh yeah you have to have a look good look at the drawing center sections and make sure
everything goes all right and as i said once you get to this step this is very easy then
so you guys i think that'll be all in today's video just uh
let me know if you like it if you got any questions uh ask me that i'll try to explain you
as best as i can and just guys please don't forget to subscribe to my channel tender notifications
