hi guys and welcome back to SITENG in today's video we're going to talk about the piling works
and i'm going to show you the two ga drawings showing the arrangement for the piles by the
two different designers and we're going to have a look at the piling schedules as well and i'm going
to tell you what you're going to find there and where to look for the information so yeah let's
go
so guys i'm going to go to our folder A&C drawings and we're going to have a look at the piling here
and the first drawing going to be ga it's a general arrangement
plan drawing when you're going to see all the piles and this is for block c
so as always we just go have a look here if this is the latest revision and uh first of all if
this is for construction so you can see now here this is C1 issued for construction uh this is good
news once uh downloaded from the from our platform drawing platform that means that's the latest one
and then uh it says yeah piling layout sheet two out of four so we know now there's a three
more drawings showing the pile side just to complete this block c all information here
uh that's okay we know the latest revision we have some notes here do not scale from this drawings
and we're going to have a look continued on uh yeah that's the our designer drawing
and we have here also continued on drawing number 64 and this side is continued on the drawing
number 61. so as you can see there's not a very complicated drawing you see the piles here and uh
you see the number of the piles the thing is in the setting out of piles we most cases we're going
to be using the robotic EDM so we're going to be actually using the drawings showing us the piles
and the pile number so that's very easy but this is just showing the piles anyway so you
can always refer to drawing and that's what i always recommend you're going to keep the
the paper copy with you all the time so we got the legend here uh denotes
denotes side boundary and for piles at gridline MJc piling details
produced by that's the other designer piling notes refer to drawing 61.
so we're going to have a quick look at drawing 61 as well and then you can see the continuation
drawing number 64. i got here number 64 here so that looks exactly the same it just shows you the
corner of the building with the piles uh we got some notes here pilot is indicated on the join
and note that why this is open i just want to close this i just want to show you this closer
pile diameter is indicated on zone and noted on the pile schedule r600 maximum now keller that's
the piling contractor have completed their final design so they're going to be 450s and 400 piles
but if you're going to be working for piling contractor or you're going to probably have all
drawing with the old piles all together and you're going to mark them up for yourself which gonna
make your life easy marking the taking from the piling schedule taking the diameter of the piles
and then marking them with different colours that's going to give you the different areas
for the piling sorry guys i got the drawing 61 now and i downloaded it quickly actually i didn't know
they're going to be notes here but i was actually first drawing so we should actually start from
sheet number one and four and in this case actually on this sheet we got the the most
information so we got all notes here you can see all dimensions in the millimeter all levels in
meters or dimension in millimeter sometimes unless noted otherwise this zone needs to be
read in conjunction with all relevant engineers architects and specialist drawings as always
setting out dimensions to be checked by contractor all the okay country concrete
nodes so that's what we might be interested in all concrete to be in accordance with BS so that's the
and pp piling specific specification document so there will be some specification about the
concrete but this is once the concrete gonna be by an order that has to be done on this level so we
as engineers as especially is doing setting out uh we're not going to be much involved in this one uh
all below ground works to be in accordance with beer so that's the code of practice yes
concrete great to be mix rc40 unless noted you i know that means unless noted otherwise so you
can see this this is rc40 so we know now this minimum concrete for 40 newtons and dc4 but i'm
going to tell you more about these things in the structures series so all reinforcement bars shall
be in accordance with bsl so that's the 500 newtons per millimeter square all wire mesh
so that's all nodes okay yield bars all concrete soffits and sides that are cast against ground
shall be protected by 50 millimeter blinding polite and [ __ ] or shattering while in the
wet state uh i don't get it it's not for piling i think that's going to be for pickups oh yeah that
was general knows maybe that's one but that's the pilot knows now so specification for piling works
uh is the ic specification for piping okay piles are to be designed in the accord and so yeah we're
gonna go usually we you just want to read it at least once uh just just to make sure you're
not missing anything but that's that's the general notes uh projection of pile covering this is quite
important for us this we're going to use later when we're going to be doing pile caps we want to
know the projection so we might be looking for it in the pile cap drawing but this is actually here
projection of pile cab reinforcement to be advised by the piling contractors that's one
but this must be however never less than 600 above cut off level four piles in compression
only and to extend to end lap with the pile cap ground beam crane base whatever it is
reinforcement for any piles with tension load so yeah we know now that 600 is a minimum anchorage
level for our steel once we gonna break the piles to the cut off level and the contractor shall be
responsible for issuing the pilot yeah so all these big contractors responsible for the piling
mat design and all temporary walls associated with the installation of the piles so that
would be us the design settlement of the piles to be maximum of 10 millimeters at working load
and the 1.5 times the working yeah so it's not very very interesting for us the the important
note for us was the one with a pile encouraged banning pie so this is about the design here so
you can see there was a face-to-ground level investigation report and based on that report
obviously the designer had just designed the piles the length of the pile and the
and the type of the pie release we got a pile pile type here based on CFA subject by specialist pilot
diameter is based on 600 unless noted otherwise by subject to pile specialist requirements
pile spacing three diameters of the pile so that that's spacing in between the piles
you cannot have two piles closer than three diameters in between final design of piles
and above assumptions will be subject to re-appraisal by the piling contractor and now
we're going to have a look at the piling schedule as always we're going to be checking this drawing
with the piling schedule they always come together so in the piloting schedule you're going to
see they're going to be 400 450 piles and you're going to have a coordinates for the pilots as well
so yeah that's the ga you got the notes here you've got some notes here as well for pi
schedule referral yeah so you on this joint we got everything really we know we have to
refer to drawing number 77 for the piling schedule third piling contractor design the us build pile
position are to be surveyed on a daily basis and issued to the client for review so this is a very
important thing for us we know now this is even uh imposed by the designer that the husband has
to be done every day so once the pile is done and that was the engineer was doing this the pile was
finished he was doing the us build survey as well and this is very good for him
once you once using your robotic instrument once you mark the point using the stakeout
you can later using the same job you're gonna be staking the point doing the ass built and
that going to show you what piles are done as well that's going to be like another level of checking
the the worst thing can happen you can actually miss one of the piles and uh trust me this is
possible I worked on one side when when project manager for the piling contractor he actually
believed he he missed one pile uh fortunately it wasn't the case he found it later in some pile
logs but he was stressed believe me so we got some notes here as well pilots indicated are for the
permanent case loads only contractor to ensure the concrete mix specification for every intended pour
for the block c is forwarded to uh retro client engineers and approved in writing concrete class
to be ac for s d s five so that's another uh thing but obviously these things guys i i'm gonna
probably tell you more about in the structures while i'm gonna be telling you about the materials
this of course all this stuff have to be approved by the client and before you use any materials
they have to be approved so that would be all i just jumped now uh to the piling schedule
that's drawing 77 which we seen on that one you can have a look you got the pile numbers here
that's how the piling schedule looks so what we're going to be looking first of course if this is for
construction so this is actually for construction uh i believe it's the same date as the ga so that
means that's okay they always go together but we as a engineers as a setting out engineers in
this case we're going to be going by this drawing so this is very important that we use in this one
as the latest one but that's the thing i i showed you we're checking the revision and once we have
it from the drawing platform that's probably going to be the latest one so i'll just show you some
notes here as well so that's the general notes in meters millimeters so we know we
don't have to go again by this obviously you want to read all of it once you have a drawing on site
you know it's characteristic value of permanent action you know scarce value of
loading variable yeah so that's all uh we're not really interesting very much in this now
as this is loads and action and uh probably some yeah loads and action piles denoted deuce to be
designed with reduced capacity due to spacing being less than three diameters so there'll see
actually there will be some uh piles which don't go by that uh first legend note we had uh
look before but they're gonna be marked different way and the contractor shall be responsible
for issuing the piling design and details pile loads indicated are for permanent case
load only any additional loads for temporary works must be provided by temporary wars
engineer where applicable so guys in this case we didn't have any of the
temporary works so we got pile number one p2p three we got the cut off level here we're going to
be using this as well later when we're going to be constructing the piling caps the pile caps we got
pile diameter but you can see here it says max diameter 600 so they're going to only be showing
here 600 but this is the piling contractor and once you're going to be working for once
then you're going to know what pile what diameter will be and as i said you're going to have your
own drawing with all markup what piles going where and that's how you're going to be working but we
what we want to know we got coordinates here and this is the most important thing for us here
so we got position of device and that's what we really need as engineers so guys i'm just going
to quickly show you because this is the other designer doing the block c and the other doing
block a so i'm going to show guys quickly the block a drawing and this is general arrangement so
you can see here now that's all block a so this is one drawing for all the block very good uh i don't
see the reason actually why making one drawing in four pieces this is only piling so piling
position and then you got a piling schedule so if obviously if there is more information you want to
split these drawings into more but anyway so we got same story which the latest revision
so there was a c4 piles move to suit existing ones yeah we had a situation here we once we were
digging down we had a existing piles in the ground and i was doing actually the survey of these
so you can see they were here existing piles surveyed on 28 with eight sixty
millimeters influence zones shown so we actually surveyed these piles we broke them down later to
the bottom of the piling mod so the designer have to change the position of the new piles
to suit as you can see here there was probably four pilots it was here here here and here
and it's now a little bit at the angle but it's gonna make its job taking the load to the ground
so yeah that's it drawing looks quite alright we got different colours and we're gonna see now
the notes as well so yeah this is typical notes do not scale from the drawing for
further general notes uh rc estimates grid setting out for sight setting out
cupping beam layout here but we're going to go through the copy for liner while this all going
to be done uh later and we're going to have a look at the drawings for these elements later as well
so uh we got a piling nose here piles are to be designed but it's a probably really similar
story to the ones we had looked before with the other designer the contractor should be allowed
to probe each pile position to ensure there are no obstructions that may delay the piling
so we found actually obstruction we were doing the probing of the piles at the higher level
but this at the lower level we actually found this one existing one so you can see the surface
was done and uh the piles new design piles were changed access for filing will be created the
main contractor so this is all typical nodes pilot reinforcement shell project a minimum of
600 or 40 times bar diameter so that's what i was using sometimes we had a really long bar so
I just kept 40 times the diameter above you can see on my video covering the pile caps
the engine should be advisability of any pile displacement so that's you can see this is also
the matter of doing the ass build so this is very important the as well has to be done
and then they have to be provided to the client all pipes are to be integrity tested to ensure
they are free of any significant defect so as you can see also on my construction site series videos
uh you can see actually the the integrity test pile and I'm gonna show you this here as well
uh a minimum of two concrete test cubes so this is all taking the cubes checking the concrete
strength if this is compliant with the design price to comply with recommendation to this
investigation report so that's the ground report done before conflict below ground to
conform to recommendations pile design for tension that okay so we're gonna have a look now we have
we have the legend here about the colours so we have a colouring denotes varying pile cut
off levels so in this case that's going to be different kind of levels for different colours
gray unlabelled pies denote contig. scheme that's okay denotes pile to have lightning protection
refer to cotton drawings so this actually i'm going to show you that's going to be actually in
the next video and i'm going to start covering the cupping beam drawings as we're going to be
connecting our lighting protection into the piles so these symbols gives us location here but we're
going to double check this later with actually RC Cutting drawing which is actually the designer for
the lightning protection for the whole building so as you could see here we got all grid lines
all the information we're going to have a quick look at the pile schedule for this one we got the
different colours here this denotes cut off level and once you're going to be doing the setting out
you're probably going to have your own drawings with the different colours but in this case i
believe your colours or whatever you're going to mark really but they're going to be denoting the
pile diameter so I'm going to show you quickly the piling schedule for this block here which is here
and you can see so it's the same colours here you know now it's a it's very good
to work with this drawing so actually later when we're going to be doing the pile caps we're going
to use these drawings just to double check if the pile cut off level is okay once we have a pile cap
depth and we know the projection of the piles are 75 mil we can compare with this and make sure
uh there's no mistake and you can see we got the easting northing here and the pile number
so what we're going to do again we're going to do the same as uh in on my first video when we were
transferring the coordinates for the main control we just copied these points and we're gonna paste
them in the notepad and then later transfer them into the EDM so uh yeah if you you can have a look
at that first video so that'll be exactly the same story we can have a quick look here at the notes
supply to be designed contractors should allow to probe so that's the same notes as from that
ga drawing schedule colouring denotes varying pile cut off levels yes so we know that from the g
as well so guys uh i think that would be all in terms of drawings if you got any questions please
uh let me know in the comments and uh always please always keep these two drawings together
and make sure this is the latest revision you want to have a piling schedule and a piling ga together
all the time with you once you're doing these jobs so you guys thank you guys for watching and
uh please don't forget to subscribe to my channel and uh turn the notifications on and as there are
going to be more and more videos coming now the next one going to be the cupping bin drawing where
we're going to see all these lining protection things all this pile testing uh so that's going to
be very interesting and i think this video is now going to be more and more interesting once we get
to the construction elements so yeah guys thank you again and see you next
time
