G'day and welcome back to Buildsum and in this video
I'm going to go over the ten building classifications that are covered off in the NCC the national construction code
here in Australia
So here's an overview of all the different classifications, and we'll go through and have a look at them individually
So the first classification will start at class 1
and it's broken up into two areas class 1a in class 1b and
It's in class 1a
There's two different building types if you like so class 1a (i) is your single
Detached dwelling whether it's single story or two story
so standalone
one owner one occupier
Detached dwelling That's 1a(i) class 1a(i) then you have 1a(ii) which is similar
but it's a
attached dwelling so in this case. We've got a duplex
Separated by a firewall so anything. That's attached. That's 1a(ii) and
that can it also includes your multi-story your two-story buildings, and it can also be a
Lot of row of town houses as well as long as each dwelling
There's one
Put one family residing in there, and they're separated by
Firewalls then they're classified as 1a(ii)
Now 1a b of sorry class 1B is
still the same types of
buildings or dwellings
It's just the way that it's used that that differs
So if these dwellings are being used as a boarding house a guest house or a hostel and they're less than
300 square metres, or less than 12 people
staying in that building then they're classified as
class 1B
All right, so that's class 1 covered off on
but then go to class 2
Now class 2 is
basically we can describe it as apartment buildings
So this is where you have people living above and living below each other and you need fire
separation not only between the the units on the same level
But you need fire separation for the unit above and the unit below
the other
Place that this could take place if you had a single
storey building that was on top of a common or shared carpark or a shared basement
That would also be classified as a class 2 building
So class 2 buildings basically apartments and the big identifier is that you have people living above or below each other
Then go into class 3 so
Class 3 buildings again, it's similar to what we had in class 1B
Except you know it's more than 300 metres
and there's more than 12 people living in this building so lots of smaller individual residences
unrelated people
Living in these for short amount of time
Basically, you know a boarding house a guest house a hostel or a backpackers
It could also be a workers quarters or in some cases
it could be care type accommodation for elderly or
Disabled if they don't happen to fall into another category which we'll discuss later
all right, so
3 Class 3 lots of
Unrelated people living in the building for a short amount of time will give you a class 3 building
then go into class 4
so class 4 is a bit of a
Unusual one. It's a
small
residential part of a larger building a class 5, 6, 7, 8 or 9 building
Okay, so you know the the
easiest way to describe it as like a caretakers
Residence someone that's there you know 24/7 they live there
and they take care of the rest of the building their part where they live and sleep is
classified as class 4 and then you can only have a class 4 building a class for classification
In a class 5, 6, 7, 8 or 9
Building and we'll look at those shortly
so that's class 4 a
caretakers type residence
So class then on the class 5 class 5 is basically an office building
So I think about lawyers, accountants
General medical practitioners and government officers and architects. That's the type of our
Type of building that we need class 5 so basically office space
Okay, then we go on to class 6
So class 6 is retail shops
all right typically restaurants cafes
Hairdresses a
funeral parlor a shopping center, they'll all come in under
class 6 retail type shops or or class 6
Then we go into class 7
now class 7 broken up into two parts 7a and 7b
first part 7a is basically car parks
that's 7a and then 7b are typically
storage type buildings so warehouses
and even if they do a little bit of displays
for produce and they sort of do a wholesale sales out of it it all comes in out as a 7b for storage
All right so 7a and 7b and then we go into class 8
So class 8 is a laboratory or a factory so this is where they're actually producing something
could be handicrafts trade sale or gain
May include assembly alterating
repairing finishing or packing or cleaning of goods or produce
Ok so there's actually work or production happening in a class 8 building
We then go into class 9
The class 9a is classified as healthcare
So think of a hospital and the reason it has its own classification is that
In a healthcare building and at hospital you sometimes have people that are
incapacitated
Whether they've been knocked out for surgery
Or they're just you know in coma or whatever. They just can't physically move in an emergency under their own steam
So even if you have like a day surgery where they actually put people to sleep for certain procedures
it could be classified as a 9a building
So just don't think Hospital there are other cases
So then we have 9b
Which are what they call assembly buildings, so don't think putting things together. It's where people
Assemble all right so Town Hall's
Assembly halls at a school sporting stadiums
Public transport and nightclubs wherever you're going to get a lot of people in the same space they're a class 9b
building and they called an assembly building class 9b
Class 9c is an aged-care building so similar to a healthcare building
But this is for aged care, so these people are have different levels of mobility
Some may be bed bound
Basically the people in a 9c building. You're going to need help to
Evacuate an emergency so the fire regulations are a lot larger a lot more stringent in a 9c building
and that's the all our actual accommodation buildings covered the last
Building that we need to look at
Is of about last classification to look at is what they call class 10 obviously
So class 10 buildings are non
habitable buildings so class 10a
carports garages
Sheds that sort of thing just a building that you're not gonna actually sleep in
Class 10b are things like antennas
fences
Retaining walls swimming pools that sort of thing fall into class 10b and
The last one class 10c is
a
Detached or separated bushfire shelter for the use of the homeowner
Okay, so bushfire shelter falls into 10c
So they're all our building classes, so obviously in some cases you may have a building that has multiple
Classes and could have a car park underneath your shops or underneath your office space
so
You know there is the chance that the building you're constructing is going to have multiple
multiple classifications
the general rule is that if
The area you're looking at is greater than 10% of the total floor area
Then it's going to get its own classification
So let's say you had a storage building
And you had a little office in the front that office was less than
10% of the floor area it would the whole building will be built as a
7b
Classification
however, if that little
Office space was larger than 10% of your floor area
Then the main building will be built as a 7b building and the office space
Will be built as a class 5 building
Okay, so there's a little bit of an overview on all the building
Classifications that are covered off in the national construction code. Hope that helps
