Transcripts
so you want to learn how to read some
drawings well you've come to the right
place because today
we're going to be learning how to read
construction drawings with keaton
knowing how to read and understand
drawings is such an important part of
being in the construction
and engineering industry and it's not
something that a lot of us have a lot of
practice with growing up
don't worry i was there too i was so
scared when i first started construction
because
i just felt like i didn't know what i
was doing i didn't know how to read
drawings and i just felt like i was so
behind everybody else
but with enough time and enough practice
and watching these videos
hopefully you'll be able to fast track
your way to being a planned reading
savant
so today we're going to be reviewing
architectural drawings all the basics
are going to be covered in this video
and for sure this can be applied to all
different types of drawings whether it's
structural
mechanical plumbing electrical and so on
and keep in mind that each designer has
their own little way of doing things so
what i show you in this video
will not necessarily look exactly the
same on your set of drawings when you
enter the industry
but without a doubt the concepts will be
the same so be sure to watch all the way
to the end so that you don't miss
anything
and also if at the end of this video you
want me to do another like series thing
where i review structural drawing
electrical whatever
please let me know in the comments below
and if you enjoy these kinds of videos
don't forget to hit that like button
and subscribe down below so you can join
our growing family here on youtube
so without further ado let's start
looking at some drawings and we'll go
into my computer
now so welcome to the computer so here
you're looking at an
overall plan view of the project so you
see here there's not a lot of detail
there's not a lot of things going on but
this kind of just shows you
just overall broad picture of what's
happening
so you'll have your grid lines here each
one and that kind of shows you the
different locations of your project
everything that you do when you lay out
on your project will be off of these
grid lines
so very important so grid lines you'll
have each building
and you see how you have each one of
these little bubbles here
that is an enlarged plan view so it just
kind of goes deeper
gives you more detail things like that
so this drawing purpose is just to show
you the overall elements you don't have
too much to go off of you can't
really build off of this right so not
only do you have your large plan views
but you have something called your
elevations
and you have your sections so i'll go
over them really quickly so your
your elevation shows you just a straight
on view if you were standing here and
staring at the building looking that way
that's kind of what an elevation would
be so if you scroll down here so you see
and how you read this is you'll look at
your elevation and it says
c1 so elevation c1 on
sheet a to 14.1
so since i've already packaged this all
together we know that we're down here
but you see at the bottom right corner
is where you have your sheet number
and it was detail c1 so here's your
elevation of the building and you see if
you're standing and looking straight on
into the building that's kind of what
you would be looking at
so sections as you can see with this
section here
and you see how this line kind of
continues through and there's this
little
i don't know nub thing over here that
sticks out
so that tells you that you're taking
essentially a slice of the job all the
way through here
looking in this direction so here your
section here is section d1
on a215.1 so you see here
a215.1
and then you have your section sorry as
you wait for it to render
so you have your section d point or you
have your section d1
and that's your overall section view
your plan so you have your plan views
your enlarged views
your sections and your elevations and
these are all in very broad
terms so you can't get a lot of detail
out of it so you have to dive a little
deeper
so let's go and do that so here you look
at studio building g
here we go b1 a370.1 and that should
give us a little bit more detail of what
this building is going to look like
so here we are again a370.1
b1 right so that's how everything is
very linked together
so here you can see it's a little bit
more blown up you have a little bit more
details a little bit more
action going on but you can see there's
actually
more enlarged plans within this enlarged
plan
so the key to drawings is you want to
figure out and try to see how you can
build things
on your own if you were to go out and do
it yourself so if you don't have enough
information in the drawings for you to
actually go out and physically know what
to do
then you need to ask more questions you
need more details on the drawings
well let's dive into this little
enlarged plan here so you can get an
idea
of what so you can get an idea of what
the real details you're looking for
in these drawings because you still
don't have enough here to determine
what you're going to be building so here
we go in large plan view is b1
a373.3 so we've arrived we're like two
drawings deep right between
your regular overall view then you're
enlarged and then you're enlarged but
then you're enlarged
so this is where you have the real
details right so now you can see that
you have dimensions for walls
you have a little bit more details about
where where this louver is going to be
um where this window is going to be the
center line of the window
what kind of walls they are so you have
a lot more that you can go off to
actually figure out how things are going
to get built
so other things you want to look at in
this drawing besides your dimensions is
you want to check out this bottom over
here
so in all of your drawings you want to
check out the general notes the general
notes will help clarify some extra
information that may not be apparent
when you first look at this drawing
so here so here you have the general
note that says refer to sheets a301.1
and a301.2 for typical floor plan notes
so that'll tell you some other notes and
more information that you have to apply
to this drawing
601.1 for interior wall types so that
will give you more information
on say these walls here so
1a the ews would be exterior wall so
that would be in a different one this
one here will
is a certain type of wall type so that's
what
a 606.1 should tell you a 606.2 for
exterior partition
so that tells you where to go for these
details three
your a372.1 is your first floor
reflected ceiling plan
and a reflected ceiling plan tells you
your ceiling heights
so it's a downwards view of where all
your ceilings are going to be
and how far they are off of the finished
floor a 604.1 for the room finish
schedule
so room finish schedule or just a
schedule is basically a table
of everything that of additional
information that you need for the job
so a room finished schedule will tell
you what is
what type of floor is in the unit or
what the wall
finish is going to be what the ceiling
finish is going to be
things like that so as you can see you
have to read these notes and they can
direct you to other drawings where you
can get more information that you don't
currently have
so going back to this drawing let's
let's dive a little bit deeper into some
of this stuff right so
let's kind of look at okay what is a
type 1a
wall right or what is a type 1 wall what
do we what does that really look like
so you'll go down to the general notes
and it directs you to the 606.1
page right so here we are a8
a606.1 and you want us to look up wall
type
1a and wall type 1. so what do those
really look like
so you zoom into these details so see a
type 1 wall
type a wall it looks like the only
difference is the type of stud that's in
the wall
a three and five eighths or a six inch
25 gauge stud
so and you can kind of see it depicted
in the drawing this is a little bit of a
smaller stud
that's a little bit of a wider stud this
kind of just shows you what
what the wall is really going to look
like exterior walls
so let's see what in the world is an ew1
so again going into those exterior wall
details
so ew1 very cool
so you see how there's this little curb
here this uh what is this four
inch tall curve so you wouldn't know
right looking at these drawings on the
plan view
that all these walls need to sit on a
curb now if you were in construction for
a while you know that all your exterior
walls you should be lifting them up
because
for water reasons right but these are
these are the details that you look at
to confirm how high is the curve how
wide do you want it to be
and one thing just for a general tip of
the day for construction
so one thing that you look at is the
width of this curve
concrete doesn't have the same
tolerances and the same level of
accuracy
as metal framing or you know interior
wall framing
so if you try to plan for perfection
when you do these curves
you're going to end up chipping out or
have filling in these edges
so just keep those kinds of things in
mind when you review these details
it really matters at the end of the day
when you're out there like shaving off
you know
quarters of an inch or half of an inch
just so that you can make some of these
details work
and you can discuss that with the
designer things like that as the
contractor
just because you should know what your
building tolerances should be
we know where our wall types are we know
some dimensions here
so okay what what kind of doors are in
here right
so we're gonna have to go on to our
schedules now so let's take a look at
this door
door g113a
so door g113a right so you see how the
schedule is set up
as just a table right you have your you
have your room name your door number
your room name
your type width height
thickness of door so all this
information for your door
so 113a counselor's office
so this is a type d door so type d
door means that so you look on the side
is there a d here okay
so vision panel single door right so it
gives you a little bit more details of
what this door should look like as a
type d
door um
okay g113a three foot wide by seven foot
by
inch and three quarter thick the finish
by the manufacturer so usually when you
have some a glass door
the architect will defer to the glass
manufacturer on how they really want
this door to be constructed because
they'll have their certain ways of doing
it
when it's hollow metal or wood you have
a little bit more control over that kind
of thing so they'll
they'll actually specify what they
really are looking for but in this case
they're not
so aluminum aluminum and then you have
some of these door details now
so you see on this different page it
tells you what the detail will be at the
head of the door
the jam and the threshold which becomes
very important when you have different
finishes right so if you have
carpet on this side or concrete on this
side how do they want those two finishes
to
to finish out it becomes more important
when you have tile like greater
thicknesses
just so that you can get those flooring
transitions to marry out the way that
you want
so again as well you have your schedule
notes what
each thing means al is aluminum your
frame construction
you'll have some extra notes here that
you have to make sure that you're
following
right so hollow metal doors and window
frames shall be packed 100
full with mineral or grout so these are
things that you need to know you need to
make sure that you're
reading through all these notes because
if you skip over this you might miss
some of the stuff that you're supposed
to be installing for the project
and that's just one door so imagine you
have to do this for every door on the
job
okay so now you know okay you have to
check out your doors check out your
windows look at the schedule and figure
out all those details and
make sure that you understand all of
that so now we're looking at okay what
are these extra details here so here's
the column details
so let's go to 800.3 on b1
so we'll split this again so here's your
column detail down here right b1
so this shows you exactly how you're
supposed to frame it what kind of
framing you're going to need
and how that will then transition to the
finish on the other side because you can
see you have stone
to probably efus out here right so now
we want to figure out what kind of
finishes are in this unit
what is the floor what's on the walls so
if you remember
if you were listening earlier we're
talking about the room finish schedule
so let's check that out alright so again
the schedule
is just a table and let's take a look at
this counselor's office g113
so you'll look at this so the floor
the fluorine g113 is cpt-3a
okay so what in the world is cpt-3a
anything in here paint all exposed
surfaces
over transitions at all transitions so
again right read all these finished
schedule notes
but i don't see anything in here about
that so
there must be another schedule out there
which will be the just the regular
finish schedule that
tells you what all of these call outs
really mean all right so here's the
material finish schedule
so cpt-3a is a shaw
carpet tile 18 by 36
so and then it's ignite tile with this
sort of type
and then you've got a product number
this is where you need to go to to
figure out what all of those things mean
so i think it called up for pt1 on the
wall so it's a sherwin williams pure
white
and this is the paint number field color
for walls
so that can give you an idea now of
what's exactly in this specific room
and you can do the same thing for the
janitor room and things like that so
now we have a better idea okay all the
finishes in here
where all these walls are going to go
what each wall type
is and then we'll figure we'll finish
out with some extra details here
so like let's check out this section
here a375.3
leave no stone unturned so again you're
making a little cut
through here so you can see here is the
doorway
here i believe this
is this column right here right this
column going up here's the second floor
so this gives you a little bit more of
an idea here's your little curve that
we're looking at earlier for the wall
types right
and then it shows you even the ceiling
in here what that height is going to be
and then this is the column on here so
you can see how this gives you a better
idea
of really what you're trying to build so
yeah that's kind of all there is to it
what we'll so you just basically repeat
this process
for every single area of the project and
researching it again as if someone were
to tell you hey
go out and finish the counselor's office
you would need to know where all your
walls are what kind of walls they are
what is the stud size what kind of board
is on there
what kind of paint are you putting on
there what's the ceiling height
all of those questions you would need to
know in order for you to build it
and that's how you're supposed to be
reviewing these drawings so i hope this
video was helpful for you
if you have any further comments please
comment below or any sort of feedback on
how i portrayed this video if you think
i could do anything better
as you can see reviewing yours takes a
lot of time i mean we focused on just
one little section and we actually don't
even have all the information
of that one small part of the building
so the more plans that you read the more
time that you dedicate to trying to hone
your craft of reading drawings
the better you'll be and if you enjoyed
