STUDENT STATEMENT
Plagiarism is a form of cheating. It is taking and using someone else’s thoughts or writings and representing them as your own. Plagiarism is a serious act and may result in
a participant’s exclusion from a Unit of Competency or a course. This in turn may require for students to pay to re-complete the module or course at a later date.
The following list outlines some of the activities for which a participant can be accused of plagiarism:
1. Presenting any work by another individual as one’s own unintentionally
2. Handing in assessments markedly similar to or copied from another student
3. Presenting the work of another individual or group as their own work.
4. Handing up assessments without the adequate acknowledgement of sources used, including assessments taken totally or in part from the internet.

Many of the workbook activities are ‘open book’ yet should still be conducted under test conditions without consultation with other students. If you are unsure of any
assessment requirements you should check with your Trainer / Assessor.
By submitting this assessment electronically you declare that all work for assessment tasks submitted for this assessment is your own with no part of any assessment being
copied/plagiarised from another person’s work, except where authorised and listed / referenced.

Part A
Project: Pelican Way Project 433324
To: Carpenter
Objective: Rectification Required for Timber Wall System Worksheet : Low Rise Structure

Figure A

Rectification Required:
1. Lintels at opening 1450 does not comply with AS1684 , Figure 3.4.4.3. It must be rectified to 2/120*45 F17.
2. Secondary Jam studs are missing under all lintels and required to be installed.
studs can be large single ones, or two or more stud nails laminated together. Please note Jamb studs in external walls and other load
bearing walls must not be:
 notched within the middle half of their height
or
 within the height of the opening.
3. One side nogging is missing next to living opening:
The maximum spacing for noggings is 1,350 mm. There is usually one nogging for walls up to 2,700 mm height. Noggings are not required to
be stress graded. Nogging thickness must be:
 a minimum of 25 mm
 suitable for fixing cladding and linings.
Noggings must be installed either centrally in the depth of the studs or flush with one face of the stud.
4. Angle Bracing required to be removed. Please Refer to figure B below for bracing installation.
BRACING

Given Bracing is not sufficient. AS 1684.2 Section 8 requires bracing to withstand the wind pressure on the timber framed structure
Any further Directive, guidance and clarification about Bracing can be found in following Australian Regulation if required during the whole
bracing process:
1. Wind classification is determined as per Clauses 1.4.2 & 1.5 & AS4055/AS/NZS1170.2
2. Wind pressure is guided by Clause 8.3.2 & Tables 8.1 to 8.5 AS1684-2
3. Area of elevation is directed by Clause 8.3.3 and Figure 8.2(A) or (B) AS1684-2
4. Calculation of the racking force can be calculated according to Clause 8.3.4 and Tables 8.1 to 8.5 of AS1684-2. Formulae used for racking
force is
Total Racking Force (kN) = Projected Area of Elevation (m2 ) x Lateral Wind Pressure (kPa)
5. Bracing systems is designed as per Clause 8.3.6, Tables 8.18 and 8.19, AS1684-2
6. Even distribution and spacing is checked as per Clause 8.3.6.6 and 8.3.6.7, Tables 8.20 – 8.21 AS1684-2.
7. Connection of bracing is led by Clause 8.3.6.9 and 8.3.6.10, Table 8.23AS1684-2
(Board, 2016; Standards, 2011)
In the given project wind classification is N2, and the racking force is given as 9 KN. Wall frame height is 2.44m which is less then 2.7m , thus
guidance for bracing can be achieved from Table 8.18. plywood sheet bracing can provide bracing capacity of 3.4Kn/m through which
correct bracing for racking force 9kn can be achieved as per Table 8.18 AS1684-2. Plywood bracing is recommended. Please ensure that
plywood used has been manufactured to the requirements of AS/NZS 2269.0. Fixing requirement is given in AS1684 -2, Table 8.18/ section
‘g’ as following (Standards, 2011):

(Standards, 2011)
In given project stud spacing is 450mm so plywood thickness and stress grade for plywood sheet can be selected as above. Plywood with
stress grade F8, 7mm thick is suggested as it satisfy the standard and will be cost effective as well. 120O*2440 mm sheets will be required.
30mm*2.8mm galvanised flat head nails can be used at spacing of 150mm for top, bottom plates and 300mm for intermediate studs. Fixing
requirement as per table 9.4 AS1684-2, for bottom plate to concrete slab, one 75mm masonry nails, screws or bolts can be used at not more
then 1200mm centre(Standards, 2011)

Sketch detailing the bracing:

Window Installation :
Windows are designed and constructed in accordance with AS2047 section 3.6.0., part 3.0 to meet performance requirements set in P2.1
and P2.2 of NCC. In given plan different glazed windows are being used. For glazed assemblies not covered by AS2047 compliance to AS1288
-2006 is required. AS 1288- 2006 sets out the data and procedures for determining the glass type and thickness requirements for all
buildings. It is referenced in the National Construction Code (NCC) section 3.6.2 for Wind class not exceeding N2. Further AGWA, Australian
glass and window Association can be referred for selection and installation of glass.
Aluminium windows are suggested for given project because aluminium windows are extremely durable, can withstand hottest and coldest
temperature and require low maintenance in long term .
The method of fixing through reveals to studs is suggested. Timber reveals are fitted first as width of reveals is suitable for brick veneer. It
does not require any additional flashing. Stud opening must be of window width of plus 50mm and height of plus 60mm as given in plan
43324, sheet no:6.1. Now window frame can be fixed once the opening is ready . (BAA, 2016).
Key points required for the window installation once the wall frame rectification is complete (Board, 2016):
Where possible, all four sides of the frame should be secured as follows:-
 Sufficient space around glass should be allowed so that window glass should not bear any type stress from wall in any direction.
 Jambs and heads must be plumb and level.
 Corner jamb fixings should be between 100 mm and 150 mm from the external comer.
 Edges should flush with internal wall lining and allow 10mm plasterboard internal lining.
 No fixings should be less than 100 mm from the centre line of a mullion or transom.
 Intermediate fixings should be at centres no greater than 600mm.
 There should be a minimum of two fixings on each jamb.
 On windows over 1800 mm wide, central head and sub-sill fixings should be provided
 As per plan 43224 , sheet number 3.2 ‘All windows to be set at 2100mm O/A head unless nominated otherwise/ if brickwork over,
adjust head height to within 5-10mm of Lintel

(Henderson & Ginger, 2008)
Seals: NCC Vol 2, Section P2.2.2 requires external wall to be weather proof Perimeter joints should be sealed on both the outside and the
inside, with a sealant appropriate to the frame surface, the substrate material, joint size, and configuration, anticipated joint movement and
anticipated exposure to weather. The sealant should be applied against a firm backing(Burton et al., 2010; Smith, 2019)
Key points required for the vapour permeable sarking or a waterproof membrane:

A vapor Barrier will be used on inside walls to reduce the risk of condensation forming in wall from the building and a sarking/ breather
membrane will be installed on outer side to prevent water entering from atmosphere while allowing the building to breath the vapours out.
Vapour permeable membrane will be used as a protective second skin behind wall claddings as per NCC vol2 Performance requirement
p2.2.2 and p2.2.3 to
 Reduces the risk of condensation formation inside the building frame in cold climates.
 Improves energy efficiency by reducing draughts allowing insulation to work more effectively.
 Protects the building frame from decay by reducing the entry of wind driven rain and dust.
Wall sarking product should have flammable index less than 5 and should not be more than 1mm thick to meet NCC, Vol2, Section 3.7.1.1
and AS 1530.2
Wall sarking should be installed in accordance with AS/NZS 4200.2:2017 Pliable Building Membranes and Underlays - Installation.
Recommended instructions for a compliant installation:(Board, 2016)
• Surface side (in or out) should be adhered strictly as per product information
• The product should be applied to a stud and rolled around the wall frame horizontally.
• When wrapping around corners, 150mm should extend around that corner.
• When applying a new roll horizontally it should overlap the previous roll by 150mm.
• Affix using galvanised staples/metal fixings every 150mm, where possible all overlaps and end joints should line up with a wall stud for
the given project of timber frames
• When applying the top layer of wrap, it should overlap the bottom layer of wrap by 150mm.
• To create an air or vapour barrier, all overlaps and nailed/stapled points should be sealed and taped. Tape used should be heat resistant
pressure sensitive 75mm wide tape.
• All damaged, punctured, or torn material should be repaired or replaced to maintain the original properties of the product.

Answer below:
Project: Pelican Way Project 433324
To: Bricklayer

Objective: Instruction to build Brick veneer Wall System for Single storey Project 43324
Given sketch for wall system required to be rectified as per following figure (applicable figures from AS 4773.2 are attached):

NCC Vol2 clause P2.2.2 require all roof and wall weather proofing is required to avoid unhealthy conditions for residents and deteriorating
conditions to building elements. Thus some of the components required in the wall and their importance are as following :
 Sarking: Sarking acts as buffer against heat loss during winter, whilst slowing heat transfer from the walls or roof into living areas in
summer. The effectiveness of insulation is evaluated by its R-value which refers to the sarking product, and often correlates to the
thickness of the material according to Australian Standard AS/NZS 4859.1. However, it must comply with the requirements of the
Building Code of Australia (BCA), specifically relating to pliable building membranes (AS/NZS 4200.1.) and must not have a
flammability index greater than 5. The Standard also requires sarking to be installed for 1800mm on either side of the point of
discharge of downpipe or spreader carrying water. It must be installed in accordance with AS/NZS 4200.2:2017 Pliable Building
Membranes and Underlays – Installation which requires product to be installed horizontally with 150mm extend at corners and
150mm overlap at joints. Joints should be sealed.{Board, 2016; Sugo, 2015}
 Vapour Barrier: When outer temperature is low then water vapour can cross the wall cavity and can get collected at sarking or outer
cladding. This further can decay the wooden components in longer term. Thus, vapour barrier is required in single brick veneer.{BAA,
2016 }
 Top and sill flashing: Clause 3.3.5.8 stipulate flashings must be fitted to the top and bottom. Because brickwork is not waterproof,
water must be stopped from getting into the house. As per BCA 3.3.1 it should be stopped at the face of the wall by applying a
waterproof finish. Water will also be able to rise from the ground into the wall, and at the sides of windows and doors. Flashings are
installed at these points to stop the water getting to the inside leaf of the wall. Flashing must project 150mm both sides past the
opening and must be embedded 30mm in brick veneer. Material must be in accordance to AS/NZs 2904.{BAA, 2016}
 Weepholes: As well as water being able to get into the cavity at the sides of the windows and doors, the flashing sheds the water
down the cavity. Therefore, at the bottom of the wall, mortar is left out of the vertical joints in the brickwork to enable the water to
flow out. Weepholes can have maximum spacing of 1200mm. They must be smooth and should not provide sags to collect water
and must not extend more than half the width of outside brick skin.{Sugo, 2015 }
 Lintel of Brick layer: Durability set out for inner components in AS 4773.1 Table 4.1 requires Lintels to be designed as per AS4773.1
Table 12.1 . The lintel should be firmly bedded in mortar with at least 150mm end bearing onto a full brick/block. Weep vents are
generally required above lintels at a maximum of 480mm centres. Each opening should have at least two weep holes and stop ends
are required to prevent moisture penetration. Masonry should have a maximum overhang of 25mm, and blockwork should be built
as close as possible to the upstand. Point loads should be applied at least 150mm above lintel flanges.{Board, 2016}

 Brick wall ties: AS/NZS 2699.1 requires brick veneer to have wall ties with corrosion protection as per AS/NZs 2699.2
Report to Client:
Alternate proposal for Cladding: Rendered Compressed Cement and Veneered timber sheeting
Cladding is the outermost layer of house which not only influence the quality of building but also influence the cost and property value. The
roles of cladding are to control the infiltration of weather elements, sound and thermal insulation, fire resistance, and the capacity for cleaning
in dusty, polluted or vandal prone environment. Both of given alternates can be compared as below
Rendered compressed cement sheeting:
Most fibre cement products have high sustainability credentials. It has generally low embodied energy . It requires low maintenance due to
stability but requires painting to maintain waterproofness. It is highly durable with very low condensation risk. It is poor insulator but has high
fire resistance. As per NCC Vol 2 Section 3.5.3.4 Fibre sheet cladding must comply with AS 2908.2 and should be fixed as per NCC Vol2 Table
3.5.3.2. As the wind classification of the project area is N2 which require the stud spacing of 600mm and maximum nail spacing of 200mm for
fibre sheeting. {Davies, 2015}
We can achieve the look of timber weatherboard from fibre cement sheet with less maintenance required as compared to timber
weatherboard. Fibre cement cladding on double-sided or single-sided wall systems can provide resistance against lateral forces or racking
shear.
Timber weatherboards: vertical and horizontal

It has various products and profiles which are widely available. Embodied energy ranges from low to very low depending on manufacturing
process, preservatives, and termite treatment. As timber is subject to shrinkage, swelling, cracking and rot unless well sealed, it requires high
maintenance and low waterproofness . It has Low to moderate durability depending on species and maintenance. Insulation varies with
thickness, sealing and density. It also has poor fire resistance and finish depends on regular maintenance and paint. {Board, 2016: X. Yu, T. Ji,
2015 }
Bracing changes:
Given alternates are nominal wall bracings. Nominal wall bracing is wall framing lined with sheet materials such as plywood, plasterboard, fibre
cement or hardboard, or similar. The wall frames are nominally fixed to the floor and the roof or ceiling frame. When fixed in accordance to AS
1684-1999 ‘Residential Timber Framed Construction’ , and properly coated in external applications, thicker cladding products can provide
bracing capacity to buildings as well as serving as a wall cladding. (Davies, 2015)
Clause 8.3.2.3 AS 1684-4- 2010 has some directives when dealing with Nominal wall bracing as following :
 Bracing may be a combination of structural bracing units and/or nominal bracing
 Nominal bracing shall not constitute more than 50% of the required bracing for each wind direction or in each storey
 Where structural bracing occurs in the same section of wall as nominal bracing, the nominal bracing in that section of wall shall not be
considered as contributing to the house bracing requirements
 Generally, a minimum of two structural bracing units shall be provided in each overall length of external wall in each storey, located as
closely as possible to the external corners
 Bracing units need to be installed at right angles to the wall area of elevation for which the bracing was defined.
For the given project’s racking force, the fixing requirements for suggested cladding systems would be as per following diagram
AS1684.2, Table 8.18

PART C:
You are planning the construction of project PN.33837 and the architect has asked you to review a potential change to the project following client
request.
Refer to the Brick Wall System Compliance – Worksheet 2 (Page 5 of Low Rise Structures - AT Worksheets).
The wall system for the ground floor however the sketch is incomplete. You are now required to:
 Describe the wall system in the diagram, sketch in the missing components and explain why they are required.
 Describe what other changes will need to be made to the structure to accommodate this change in design.
 Identifying whether your solution to the problem is a “deemed to satisfy” or performance solutions.
 Reference the NCC Volume, Section and Clause(s) and relevant Australian Standards as part of your response.
Answer below:
Project: Pelican Way Project 33837
Objective: Review of ground floor, Brick veneer Wall System compliance requirements for Double storey Project 33837
Given sketch for wall system has changes requirement for structural compliance as per following figure (applicable figures from AS 4773.2
are attached) :

NCC Vol2 clause P2.2.2 require all roof and wall weather proofing is required to avoid unhealthy conditions for residents and deteriorating
conditions to building elements. Thus to achieve Structural compliance requirements following elements are required:
 Sarking: The effectiveness of insulation is evaluated by its R-value which refers to the sarking product, and often correlates to the
thickness of the material according to Australian Standard AS/NZS 4859.1. The thermal rating (R-Value) of a double brick wall (RO.50)
is about the same as an uninsulated brick veneer. It must comply with the requirements of pliable building membranes AS/NZS
4200.1. It must be installed in accordance with AS/NZS 4200.2:2017 Pliable Building Membranes.{Board, 2016; Sugo, 2015}
 Top and sill flashing: Water can enter the wall system at numerous locations, including individual masonry units, mortar joints, the
interface between the mortar and the masonry units, at the tops of walls, at cracks, and at penetration details such as windows,
doors, and pipes. Clause 3.3.5.8 stipulate flashings must be fitted to the top and bottom to avoid penetration of water. Flashing
Material must be in accordance to AS/NZs 2904. They are required to be installed as given in above figure from AS47763.2. Flashing
should be installed at base of wall, at shelf angles, above window heads, below windowsills and at other locations where air space is
interrupted. For flashing laps, provide minimum 6 in. overlap and seal. At the discontinuing point, form end dams by turning ends up
at least 1 in. into a head joint.{BAA, 2016}
 Weepholes: Flashing sheds the water down the cavity. Therefore, weepholes are required at the bottom of the wall, to enable the
water to flow out. Weep holes should be placed immediately above flashing. Open head joint weeps preferred. Spacing
recommended to be no more than 1200mm {Board, 2016}
 Lintel of Brick layer: Durability set out for inner components in AS 4773.1 Table 4.1 requires Lintels to be designed as per AS4773.1
Table 12.1 .{BAA, 2016}
 Brick wall ties: AS/NZS 2699.1 requires brick veneer to have wall ties with corrosion protection as per AS/NZs 2699.2. Select one of
the following tie types: unit ties, joint reinforcement, adjustable unit ties, or joint reinforcement with adjustable ties. Space ties at a
maximum of 32 in. (813 mm) horizontally and 25 in. (635 mm) vertically

Part D:
What do I need to do?

The client has purchased another block of land, a one hectare site on top of a hill 3 km north east of Mount Hotham in Victoria. The
site is surrounded by forest. The client wants you to build a dwelling using the original design for project 33837, refer file PN33837
Leary Ave - Plane Pack .
You are now required to:
 Describe what the additional loads and stresses will be as a result of the location.
 Identify and explain what changes would be required to the design to meet compliance requirements for this
location including the relevant NCC codes and Australian standards that must be met and who would certify this
compliance.
Answer Below:
Mount Hotham is a mountain in the Victorian Alps of the Great Dividing Range, located nearly 6,109 ft. above AHD. As per NCC, Vol 2, Figure
3.7.5.2 the location is considered to be Alpine region where snow load are heavy.
Additional loads and stresses that can impact the design and construction process are:
 Structure — Structural loads can come from topography and natural l structures around the site as forest trees, ground condition,
stormwater natural drainage ways, and site slope. Thus the design has to go through the engineer approval to be safe.
 Environment — Environmental constraints of the location are stronger wind site, more rain, snow, bushfire and extreme weather
exposure for cold and hot.
 Space — the site won’t have any constraint on size of building but can affect the safe access for building. Specific design solutions may
be needed to overcome issues of difficult orientation, circulation and access

 Location — remoteness, proximity, servicing access to infrastructure and services for the occupants will have to considered for building
design.{Council, 2020}
Changes required to design to comply with Australian standards:
NCC vol2, Part 3.7.5 sets out the guidelines for construction in Alpine area to satisfy performance requirements of P2.3.6.
 External doorways: NCC, Vol2, Part 3.7.5.2 instructs external doors should open inwards with marking on them ‘open inwards’
 external ramps: NCC Vol2 Part 3.7.5.3 states that External doorway must have a gradient not steeper than 1:12
 External Doorways: NCC Vol2, Part 3.7.5.4 Requires the building to provide clear means of egress by keeping the distance of external
wall from allotment boundary more than 2.5 m if the wall is 3.6m above ground. If the doorway discharge in a court the wings of
building should be minimum 6m apart. In case of doorway opposite a barrier construction should be as per following figure
 External trafficable structures: NCC , Vol2, Part 3.7.5.5 requires building to have access bridges, access for firefighting vehicles.
For example, external stairways, ramps, access bridges or other trafficable structures of a building must have:

- a floor surface that consists of steel mesh or other suitable material if it is used as an exit
- any required railing (balustrade) or other barrier constructed so that its sides are no more than 25% solid
 Timber framed walls should comply with government building regulations and AS1684. Framing members should be a minimum of
MGP10 stress grade and joint strength group JD5. Stud spacing should not exceed 600mm centres for 1200mm sheets and 450mm
centres for 900mm sheets. Engineered brace boards are one of the good choices to comply with the bracing requirements .
All engineered brace board is manufactured in accordance with AS/NZS1859.2 specifically for Australian building and
construction. Engineered brace board is designed to resist horizontal racking forces applied to buildings with cavity bracing in external
wall frames and to resist uplift in braced wall systems. These brace board is engineered with Moisture Resistant resin for enhanced
durability.{Standards, 2011; Board, 2016}
As per Alpine shire council ‘For building in Mount Hotham, you need to obtain permission from the Alpine Planning Division of the
Department of Infrastructure before applying for a permit at the Alpine Shire Council’. This is because State Government controls that land,
not the Alpine Shire Council. But keeping all the addition site loads in mind, Engineer approval is recommended to carry design of PN33837
Leary Ave - Plane Pack at site of Mt Hotham. {Council, 2020 }
