hi guys and welcome back to SITENG this is another video from construction drawing series and this is
a first video from the tool covering the piling mud works and in today's video we're going to
have a look at the piling mud construction drawing we're going to have a look at the specification
as well i'm gonna show you also the level survey i have done for blocks A and C as this is going
to be the very first thing you need to do after we have our uh setting out information and then later
i'm just going to show you how it looks in reality on this nice photo taken from the crane so yeah
guys let's go so guys as before i downloaded few drawings from that A-site uh i'm not going to be
showing that again as you know how to do it now uh i'm just open my folder here and c we're going
to go in the drawings and we're going to open another folder which will be piling mat now
and then i'm going to move here i got the drawing here with the piling mat which is this one and we
can actually go back here and in the drawings we can do another folder now which we're gonna go
specification folder that's where i'm gonna be keeping the specifications for
all the works i'm going to move the file here and i got one page extract from the specification
which i'm going to put here and i'm going to show you this as well and another folder in the main
one i would open number three we're gonna put uh surveys here and i'm gonna move our survey in here
so guys before we start looking at the actual drawings for the piling mat the first thing we
need is the survey so as you can see here this is actually block a and see here the works here
underway so obviously before this happen we want to do the survey and once we got all coordination
once we got main control we can set up already and the very very first thing uh would be the survey
maybe just after or at the same time when we're going to be marking gridlines uh all around us
to make our life easier so i'm going to open this drawing now and i'm going to show you the survey
so you can see here this is block A this is block C and i showed all the levels here to know and
actually to send later to our QS to have a look at it and just to just quantify the amounts of
muck going out and the crush going in you can see i surveyed the hoarding as well here with
the red line and i overlaid the existing services here the water and the new drainage diversion so
uh yeah there is a hoarding here as well so it's quite good information we got the levels here
so the first job is done we got the we got the levels and now we're going to be looking at the
piling mad drawing just before this we can actually
go with and save it as a pdf before we're going to send it it depends what form our cue is or
whoever wants it well we can just print it this way maybe we're gonna go landscape preview
yeah so yeah it's visible and i can just save it maybe as a pdf why not
uh i'm going to put it in the same folder we had so we got A & C surveys okay so after this
we want to have a look what we're going to be actually building what
material we're going to be bringing what actually we need to construct our pile mod
so that going to be as i said in the drawings i put piling mod and this is the first drawing here
so yeah the drawing looks quite all right as you can see the first thing actually we're going to
be looking for the piling mat for the contig pile wall all around it so that would be the very first
thing and after this that going to be actually in next video i'm going to show you how we're digging
down and then going to be another big piling mat there so we're going to go first thing as
always we want to make sure that's the latest revision and uh and if it's for construction
really so we got this is c2 this is from july piling sequencing revised to remove all the MSU
so that was there you could see actually on my background here you can actually see there is
MSU unit in here which is under the deconstruction which is under the demolishing at this level but
before this uh obviously this was in use so that was actually quite interesting continuous by wall
had to go this way to enable the construction for the temporary condition
but let's go back to our drawing here and then we're gonna see so now we know this is the latest
revision obviously checking on a site because that could be C 3 C4 but that's the latest one
uh we got the general notes here do not scale from this drawing all the dimensions to be checked on
site all dimensions in millimeters unless noted otherwise all levels in meters structural size
here and shall not be modified this joint is to be read in conjunction with all the relevant
drawings and specifications we got here you see the pile match sequencing so stage one polymer
we know now we got the high level on drawing 46 so that's the draw that's how we're doing we're
looking at now it's 46 to enable installation of pilots of contiguous wall for majority of basement
so that's what we're going to be doing that's the first after we did the survey and as you can
see here on the drawing got some existing levels but then you can have a look here this is denotes
existing levels from heap volumes and level survey by dj dunphy so that's not my survey it could be
changed that was from 2018 so 100 that was changed so that's another reason why we have to check it
before we actually start any works uh we got here a client to confirm
status of sewers to be abandoned special occur to be taken were newly constructed existing abandoned
water mains depth approximately 750 per guidelines okay so that denotes our side boundary line
so you could see on my survey there was a hoarding line just surveyed so we show where we are really
and as you can see there are some services and this is actually the previous package of wars
with under there was a big drain diversion to enable constructing of blocks a and c
but i'm going to try cover in another video covering the drainage as this was very
interesting work but just to let you know before all digging starts you need actually make sure
you got all services information with you so you can see the designer put the existing drainage
you can see here is existing storm water manual existing fall water manhole and we got
some existing main water service as well and this obviously has to be removed so what we information
we have here we got actually the width of our pile mad so you can see it's 12 meter from the center
of the pile mad this way and two meters from the center of piles this way so the rig is going to be
sitting in here and that going to be actually hit and miss while piling but i'm going to i'm going
to tell you a little bit more when we're going to be talking about the piling itself so extent of
piling platform ppl so that's the most important thing for us it's the piling platform level is 46
330 so that's that's very important thing what else i can see here geogrid tensar
SS40 to be laid between formation and underside of piling mod so drawing itself is quite okay
and the very good thing here we got actually coordination for the grid lines
as well here the wMJith XXB XX2 as well so this is useful in this case and also what we
got here we actually have a section through the piling mod which is very good we can have a look
what we're going to be building so this is probably typical section but in this case
uh a typical piling mod material we're going to jump in the specification in a minute just to have
a look what we what we need to bring to construct the piling mat 46 330 so actually on this side
sorry guys we have actually platform level here is 46 880 so it's different yeah so we
got the steps here one in ten uh they're going to be ramping the platform yes one ramp here
one from here so they're going to be changed in the levels as well this is actually 46 150
and we got so we got one two three changes in the level so that's very good yeah we know now we have
to keep an eye on it all the time and to mark where the platform gonna be changing its level
so uh that's quite interesting so that's why we have here just the piling platform
level ppl which is going to be changing as we go around the building so what we have here
we know now we got formation level formation level it's our dig level so that's going to be
underside of our piling mat we got allow for geo grid and side strip level all material
below this level to be remodelled if required so we got a note here as well where the msu is
for high level piling mod in area of MSU drawing f45 and C pile image sequencing note stage 3
on this drawing so node 3 was in here it's about that gonna be later and away high level on drawing
enable installation of contiguous piled in the area of MSU which i'm going to show you guys
later anyway so we could actually ask ourselves if we have all the information here for us if you got
all we need so we know now here yeah the platform here are going to be 14 meters wide and i'm going
to be changing in the levels here having this level is 46 150 ramping this up to 46 330 so it's
not the big difference and then uh this here gonna be a little bit different because you got the
10 meters only here and that's gonna be it looks like this is actually in the middle so five meters
off the centers of the piles each side and the reason for it is uh i think this is the
side boundary here so that's our uh hoarding so this is possible here for the piling rig
to go backwards and drilling the piles uh as they go as this is going to be a bit more difficult as
you need to turn the piling rig so this is a big machine so this is actually much easier for them
so uh i think this is all guys we got all the information we need really we got some services
we know we have to be careful and then if they are that we just have to rip them out later but
as you can see the levels the inward levels of these manholes telling us that we're not going
to touch it they're going to be much lower but we just need to keep an eye on it we just need
to remember when we're going to be going uh to the lower piling mod so this is the levels 45 950 so i
had my levels as well on my survey and this is 41 so we don't need to be worried about any services
at this point obviously we need to check with the client and with all information we can get
if we have any other services than this and then later obviously use the CAT scanner, or provide
some GPR survey for this building uh yeah guys so i think that's it if you got any questions about
all the other information just please let me know and leave some comments and then now i'm gonna go
to the specification and we're gonna have a look quickly what that pile mat has to be built from
and i got it in the drawings piling mat and i got a spec here
and uh you see the piling mod is based on the following piling ring information received by the
piling contractor but the rig is to be confirmed so that's going to be actually the piling
contractor providing the information about the rig they're going to be using
and based on this obviously the pile mod has to be checked against if it's compliant but you can have
a look here the piling mod is to be constructed with 6F2 granular capping material so this you can
actually see on my uh construction site drawing video when we were installing the mud so that
was the the same material there the crush stone in accordance with the specification of highway
works so now we know now what material we have to use and then what specification we have to go
by so specification for highway works that means we can have a look uh how many layers we have to
install now providing we're going to use in 500 millimeter mat and then how many passes of the
roller we need to perform to get compliant with this specification so here it says
total depth of piling mud is to be a minimum of 500 deep with a geotextile membrane underneath
so yeah that's that's the basic information here there's all other stuff as well but maybe i just
quickly guys go back to this drawing and this piling mad here is to be actually one meter deep
yes i just i didn't tell you this but this is quite actually important because we got
the level of the top of the mat so in this case actually our dig level obviously going to be 45
150 as we're going to be installing one meter of that 6f2 crush material which we had a look
just a second ago we can have a look here as well this is 1000 millimeters as well
and we had three changes in the levels so maybe just quickly make sure that all that mud has to be
uniform and the same which will be probably but just you want to make sure yeah it's 1000
in this case 1000 in this case yes so whenever we got this information we got the extend of platform
we got the piling platform level 46 150 and the depth of piling platform so now we know straight
away our dig level our formation level will be 45 150 so that's okay if you can have a look at
the level here this is obviously done before but assuming this is the existing level so 45
150 formation level so in this case we need to dig only around 300 so we need to take
only around 300 from the top of existing level to install our mat so yeah guys that will be all
in today's video i just want to quickly show you because i got a nice photo from the crane
so this is our block a and c and i'm going to show you the photo here i got actually this is
on my desktop as well so this is our A and C and this is actually the works you can see the
bits of capping beam already done and we actually dig in for the lower
uh piling mod which i'm going to show you in the next video but yeah guys that's how it looking in
reality that's how it looks on the drawing here uh i think this is good to see and then yeah guys
thank you again for watching and uh please don't forget to subscribe to my channel and turn on the
