have you found a mistake on the drawing is there any discrepancy between two other trades my name
is Greg and welcome to SITENG in today's video guys we're gonna do the RFI and i'm gonna explain
what it is and how to do it we're gonna use for it the two drawings i overlaid the other day and guys
just make sure you're going to watch till the end because i want to show you why the information on
the drawing is the very first feed you should go through so let's go and have a look at that RFI
so guys in the last video uh we actually overlaid this two drawings general arrangement
the structural drawing here for there for the concrete so what we're going to be setting out
and doing and then we got M&E drawing here and uh what we're going to do today now because we see
some discrepancy here in between the penetration showing on the structural drawing and in between
the m and e we're going to raise an RFI here and as you can see here we got bathroom here so that
penetration makes sense and this penetration here next to the toilet bowl makes sense as
well but we're missing this on the structural drawing and instead of these guys we got it
actually opening showing in the middle of the door here that's why we're going to ask the question
to confirm the position of the drawing and then guys uh just stay till the end of it because i'm
going to show you why the reading of the notes and the reading the drawing the information on
the drawing is the most important thing just before you start doing anything else but this
RFI guys it's the example what we would do if we had the information like this and how we would
erase RFI if we needed so what i would typically do guys because the language for the engineer
the engineers language is the drawing so i always try to attach the drawing to the RFI i'm sending
when i'm going to explain quickly what i need and depends of the of the situation obviously
we're going to be describing i always attach the join so i would take this one for instance let's
take only one penetration here and we're going to ask here as we see clearly discrepancy here
so i would mark it like that and i would so i'd go like this and i would just ask maybe please
confirm my position of the penetration uh what i would do obviously i'm going
to just leave it white so i'm going to be clearly visible i'm going to make the
the phone bigger as well and i even do the line uh maybe i just do black and a little bit
thicker as well and i'm just going to work a little bit on my arrow so that's what i would
actually attach to my RFI guys now it is so you can clearly see when you open this drawing you see
it's too overlaid so you see the red one is the structural drawing here and the light blue we
overlay the M&E which shows the architect drawing as well here showing you all the layout for the
building here so once you open this you clearly know please confirm position of the penetration
and you can see something is wrong that's what i would attach to my RFI guys but what i do myself
obviously it depends what job you're going to be working on as some people they're not going
to even speak with you till you actually race official RFI but typically what i try to get i'm
sending the emails and i'm going to try to get the answer just before that and then please remember
that the responding for the RFI is typically seven or it might be even 14 days depend on the job
you're doing so they might actually have more time for the answer than you need actually to install
this we assuming the goodwill here and solving the problem is the most important thing so i think we
can communicate well and as i always said the communication is the key guys if you're working
on site communication on site is the key for you and then you can see there was a miscommunication
here between the design and m a definitely so that's another one that's that's the communication
problem here there was some some discrepancy but as i said at the end of the video uh you're going
to find out it wasn't that bad really so that would be the drawing i would attach and also
if i would say the email i typically say the email as well with a question i would probably just take
the snapshot of it maybe just so we're going to see the the grid lines here i'll take the snapshot
scrounge will see and i'm gonna put mail i would just paste it in just clearly say uh what's going
on here guys just kind of confirm but to make it official guys just RFI i would i would put here
the text for it and you're gonna be dependent what platform you're gonna be using or if you're going
to be sending just the RFI through the email and then you're going to be keeping some record of it
or like a site i showed it the the other day you can actually raise an RFI through the a side or
through some platforms you're using on my last job actually it was a few other platforms and
the the procedure was a little bit difficult a little bit time consuming i would say maybe not
difficult but sometimes people just overthinking and making making simple stuff too complicated
really so what we would do in this case guys we'll probably ask for the penetration so
there is a discrepancy between struck structural uh drawing and we're going
to put a number of drawing here obviously and i'm a knee drawing i'm only drawing
number of the drawing we want to hear and make sure we're using the the latest revision and then
there's discrepancy we got a drawing attached so you can just write please confirm position
of the penetrations or issue an updated drawing and then please see a touch i will personally
leave it like that guys once you once once you're going to read this if you'll be designer uh please
there is a discrepancy between structural domain uh number and the level obviously
and then uh between the m and e and then please confirm position of the penetration so we know
it's it's a penetrations and then uh issue an updated drawing or yeah confirm so and
then obviously the RFI you're going to need the number as well so you can keep a tracker of it
so that'll be let's say no be our RFI 001 and the title for it would be a penetration position
discrepancy and that's it guys that's all you need that's how you're raising rfi so don't be afraid
of it i remember when i was doing this stuff for the first time i just i wasn't sure you know i
was writing few times the same thing and it's always like that so it's normal guys everyone
go through it every single thing you're gonna do the first time you're not sure how to do it
so i think that's gonna help you just just just don't be shy just don't be afraid of it
just raise it and then try to explain the best as you can and as i said the drawing is the language
of the engineers once you mark it it's clearly known and every everyone knows what's all about
you know once they're gonna open the drawing you can see clearly something is wrong so you don't
want to spend two times explaining in between grid line c m and c and there is a penetration is
no point of doing that guys uh you just want to as we we are engineers we want to take the least time
and then we're going to explain it the best so we're going to have an answer and we're going
to have a results but using the minimum time uh to get this so guys that was the example of the
rfi if we needed guys and that's why i told you at the end of the video i'm going to show you
why the reading of the information provided on the drawing is so important because uh in real
life we we wouldn't even ask that rfi but as i said that was examples that how you want to be
raising your rfis so as you can see here i got a note here at a big note for setting out the
coordinates for services within slab refer to architects drawing guys so this actually tells
you all this penetration shouldn't be set out as per this drawing and there's no dimensions
actually to it and this is a little bit confusing guys because some people they just bring in the ga
drawing to the controller and they then later on the slab they busy they set it out as per as per
the join as a penetration they got here so this is a little bit confusing maybe maybe if i will be
the designer i wouldn't even put them here because this might actually cause some problems so then
we're going to go to the architect zone and then you see we've got a penetration the same as shown
on that m e drawing we got a penetration which makes sense here uh we got we got the bathrooms
here and all the penetrations here actually as they should be and as you can see here we don't
have a clear uh setting out in terms of position of the grid lines so what we would do guys if
we will be doing setting out on for the slabs we will have to take the information from this
architect drawing using a card and just bring them on our structural drawing a little bit of work uh
in preparation uh for the setting auto maybe that would be your senior engineer job if you're going
to be too busy to do in setting out so guys that's why i'm saying this is very important to read the
information here provided on the domain as this might be confusing here and that would be actually
our error if you set up as per this drawing so that's our job as well to keep an eye on this and
ask the question if there was a discrepancy but if there is a clear information what we
should use we we need to bring that information together for ourselves and we need to make sure
we're going to do it right guys so i think that would be all in today's video and if you liked it
please don't forget to leave a thumbs up guys this helped me to grow this channel and uh helped me a
lot and shows me that uh whatever i'm doing here makes sense and then guys please don't forget to
subscribe to the channel as well if you didn't do it and then follow my linkedin page they're gonna
be more and more coming now i i promise you that and you don't want to miss it so see you next time
