hi guys and welcome back to SITENG in today's video i'm going to show you construction of
the crane base cranes are already installed behind me but i'm going to show you all the
process of the crane based construction we're going to set the anchor legs and then i'm gonna
show you what you need to know to set it right so let's go so guys this is our uh crane anchor here
so that's your main job to set this uh at the correct level in correct position
in the crane base so as you can see here it actually says uh block a tca1 so all information
there i got drawings which i'm going to show you on the construction drawing series for this
you see the jack bolts and these jacks uh i show you in the green base i set it already
lines for it so that's the jack here the jack gonna go into the tube and the tube is
actually here it's done quite nice this time this these tubes are actually in the center
so they just offset from the center of of the tops i'll just show you that how it looks from the top
so yeah i got position of these four pins i got coordinates for it so i set it there but
what i'm interested in this position of this tube is i'm going to set my jack bolts and when we're
going to be dropping the anchor we just drop them straight on the jacks and trust me it works and i
show you that it works and then just later we're going to shoot reflector less we're going to be
shooting just the side of it we're going to give the offset i believe this is 240 so we're going to
do 120 offset this shade this is 220 so 220 to 30 you just measure it with the tape anyway and half
of it gonna be our offset so that jax has to be set at the proper height as well so as you can see
this one maybe you can see but the trust me this is two meter height anchor and uh what they want
they want 400 above the concrete to be protruding from that and then 1600 into the concrete
so when you see on the drawing on the drawings video this uh our crane base is 1750
that means uh our jacks have to be 150 above the the soffit of the crane base but uh because
we're using the core deck 100 of core deck i'm going to set these jacks 250 at 250 height so
you can see this is regulated so i'll set the 250 i'll actually going to set 255 maybe 260 a little
bit higher which gonna give me uh the the easier way to just drop it a little bit and adjust it
when we're gonna set the base and i'm gonna make uh sure it's in position then we're gonna start
a little slowly slowly moving this ones just to make a perfect level as we got only two mil
uh accuracy in the height uh difference between the legs so it's not much but it's trust me it can
be done i got it i got one base in one millimeter now all the legs in in same level only one is only
one meal different so it's it really can be done it's not end of the world you just have to be
accurate and just actually you can follow you can follow this video and you should be fine
so
we got the bottom mat already in the reason for it was we didn't have anchors and we have to let the
fixtures work so this is more difficult for me now as i got the centers mark on the core deck but i'm
going to have to cut through it and then try to set them legs as i showed you before that 30 mil
offset from it the only problem is it you see the hole so we can actually fix it to the blinding so
on the next crane base i'll actually show you show you how it should be done so the crane
so the anchor is going to be in position even before the fixtures start and that's what i'm
going to do on the next one yeah the crank anchor is coming now to the base i'll show you what i did
i just marked the centers of the legs and then uh as i'll better sign the people [ __ ] yes
and then i send that 30 35 millimeters offset you see the arrows so this line is going to stay
and there is only offset for the tubes and you're going to see the legs should be just
exactly in the middle after we set them so just in a second i'm going to show you
well the crane base is set i put my edm already down uh i just couldn't record
while i was doing this but you can see the crane base it's in there uh i was shooting i was using
actually reflector res just shooting the level of top on top of there and telling the one lot
to move it up and down we had to go around 10 mil down as i said before i set the jacks a little
bit higher as it's easier to go down instead of going up the position was actually perfect
maybe it was big luck with it but it's really perfect and then same with there with the lines i
what i do i just shoot the legs i shoot the steel leg and i do and i check the offset
and then before we pour i just check the top uh the top pins there as well but i i checked and
they were in the center so that offset line always worked perfect and uh i just double checked to do
the us build really just just a pre-pour and then after after i'm gonna pour i'm gonna do another
one and then i'm gonna shoot in the beams but then it's well enough if you shoot the reflector less
using the the the reference line and shooting the sides of these profiles of the big legs
and uh yeah that's it when they're gonna finish the top seal i'm gonna show you again just the
just the pre-poor inspection maybe and then when we're going to pour it and that's going
to be our crane base and obviously i'm going to show you in another video the crane erection
video you're going to have a look how the lads install in the crane we're preparing the crane
base for the back filling now we have to actually backfill it uh slowly and then carefully from each
side slowly and slowly not to move anything and obviously after we're gonna do that i'm gonna
double check the crane anchor position i'll just show you how the anchor looks now
anchor in there top still there is only top one to come on top of it
we got the lightning protection here connected this is a tape now it it's going
in two legs that's what design wanted so you got one here one on the yeah opposite corner
grain base is ready we pour in the concrete now we reverse in the roar is straight to it it's not
gonna be around 90 meters poor so that's the way i just told lads to be careful start from the corner
not to move the crane anchor by any chance not given that i'm just shouldn't move but you never
know we need to be very careful and i'm gonna keep checking it in maybe an hour after a few loads
so yeah that's it finishing the concrete i'm going to show you what to finish
so whenever we pour the concrete we need to collect the cubes in this case we got 88 / 89
meters of concrete to be poured in that crane base so we're going to take three sets of cubes - 12
cubes and then i think the first is gonna be crushed at seven days and then we're gonna decide
on the on the other ones we'll see how the strength of the concrete grows so yeah that's it
so guys this is the day after pour i'm gonna do today the us build survey on the slab slab levels
obviously i'm gonna double check the the leg uh levels as well and i'll do the asbuilt of that
pipe there so i can submit there to the client
and uh yeah the concrete finishes as you can see because they're going to be slapped on top of it
so this is actually poured to the soffit of the basement slab there's no requirements really for
the finish and that's it yeah i'll show you maybe in construction during series i'm going to show
you the the us build i'll put it on the drawing and yeah that's it that will be all for this
