Q
No Answer Reason or Explanation
1i Suitable
There are certain parameters that need to be considered when
considering the suitability of a building in terms of wind
classification. These indicators include height, topography, and
shielding classification. Looking at walks design, we can use the
height of the building as our main indicator to determine its
suitability. We can therefore say that wind classification will
work best in this case because the height of the building is
5175mm which falls within the required limit of 8500mm as
shown in AS 4055, as such, this will apply in this case in
accordance with the wind classification as stipulated in clause
1.4.2 in AS 1684.4 code.
Ii Suitable
Timber construction is essentially limited to L-shaped and
rectangular structure. This is in compliance to the AS 1684.4,
Residential timber framed construction as specified in clause
1.4.3. We can therefore conclude that the design is within the
flexible limits.
Iii Single and two storey
AS 1684 states that timber construction can only support a
maximum of 2 storey as indicated in AS 1684.4 clause 1.4.4.
Iv Suitable
In compliance to AS 1684.4, Residential timber framed
construction as specified in clause 1.4.5 which states that the
maximum width of the house should not be in excess of 16m
excluding eaves. Seemingly, Mr and Mrs Walks house complies
with this clause since it has a width of 11870mm which is
within the permissible limit of 16000mm
V Suitable
The wall height of timber construction is key to ensure that the
building is structurally sound, as such, the AS 1684.4 demands
that the height of timber wall construction should not exceed 3m
Looking at Mr and Mrs Walks house has a height of 2450mm
which is certainly within the permissible limit as stated in AS
1684.4 in clause 1.4.6.
Vi Suitable Hanging rafter in timber construction should not exceed
750mm as stipulated in AS 1684.4 Residential timber framed
construction, as stated in clause 1.47. Looking at our design,
its hanging rafter is 450mm which is definitely within the

Building and Construction 4
required limit hence deemed to be suitable for timber
construction.
Vii Suitable
Timber framed construction for residential houses will adopt a
hipped roof type as stated in AS 1684.4 with a roof pitch of not
more than 30⁰. Walks family design takes the hip shaped roof
which definitely satisfies the requirement with a roof pitch of
20⁰ which falls within the required limit as specified in clause
1.4.8.
2 Yes
The topography of the site is suitable for this design structure
within a floor plan stretching within the required maximum limit
hence able to withstand the deflection pressures
3 450mm
4 300mm which is in compliance
with the BCA
5 No requirement for filling Suspended floor can be used in this construction which means
that pad foundation will also be adopted in this case..
6
50kPa,
Controlled fill is where a tested
material imported to the site or
found on site is placed in layers
of 150mm, the moisture content is
regulated by adding water using a
compaction equipment (Roos,
Woxblom, & McCluskey,
2010).
A rolled fill is an embankment of
the earth or rocks where the
material is placed in layers and
compacted using rolling
equipment (Roos, Woxblom, &
McCluskey, 2010). KPa is a
unit for measuring pressure.
Allowable bearing pressure is the
maximum stress that can be
applied on a foundation such that
it is able to withstand the shear
failures.
