Project 1 – Work readiness and structural planning
Part A: Getting work ready
Note:
This is a compulsory pre-assessment task that you must complete to
enable you to carry out practical assessments later in this course.
However, this task will not contribute to the results recorded for your
assessment in this unit.
In this pre-assessment you will take steps to get ready to enter a construction
zone so you can carry out some of the assessment tasks for this course, and to
prepare you for work. This will guide you through:
 obtaining a ‘White card’ to enable you to safely and legally enter
construction zones
 seeking the appropriate permissions so you are covered by Open Colleges’
and the licensed builder’s insurances when you enter construction zones
 making links with the building and construction industry.
Step 1
Note:
If you already hold a ‘White card’, simply upload a copy of this using
the submission instructions above.
a) Complete your ‘White card’ training through your choice of provider. There
are many providers who offer the ‘White card’ through both online and
Open Colleges
32636/01 Apply structural principles to residential low rise constructions.
Page 4 of 12

face-to-face instruction. They can be researched by searching 'white card
providers' online. Most training providers will charge a small fee, so shop
around for a competitive price. ‘White card’ training should take
approximately 3 to 4 hours to complete.
b) Submit evidence of your ‘White card’ to Open Colleges i.e. upload a copy
of your ‘White card’ with this assessment to OpenSpace using the
Assessment Upload links in Module 4 of this course. This must be provided
in order for you to be covered by Open Colleges’ insurance.
Step 2
a) Approach a licensed builder or construction company, and obtain permission
to visit their construction site to observe building and construction processes.
This will help you complete the assessments for this course that require you
to observe the real workplace.
A great place to start to find licensed builders you could approach is the
Housing Industry Association (HIA). They offer a range of:
1. membership benefits
2. events
3. publications
4. industry and business information
5. products and services.
You may also go to trade build and enter 'builder' in the dropdown menu and
your suburb - you will be able to find builders in your local area who you could
approach for your site visit.
b) Use the information and script provided in Appendix A to help you with your
first approach to a licensed builder or construction company.
c) Ask the licensed builder to complete and sign the ‘Permission to visit
construction site’ form.
d) If you are currently employed by a licensed builder or construction company,
you may obtain permission from them.
e) Submit the completed ‘Permission to visit construction site’ form, signed by
the authorising licensed builder i.e. upload a copy of the form with this
assessment to OpenSpace using the Assessment Upload links.

Plan for the erection of the structure of the Casey house (Class 1) and fencing
(Class 10) including:
 applying structural principles when planning the erection of the structure
of the house and fencing including footings, floor system, structural and
non-structural walls, roofing and external wall cladding. Refer to AS 1684 –
Non-cyclonic.
 explore forces and loads, and mechanical properties of material fuel loads.
 analysing plans and building materials for structural integrity to withstand
bushfire, high winds, earthquake, etc.
 seeking professional advice/input from architects, building designers,
engineers, etc.
 outlining how you would coordinate the demolition of any existing
structures (e.g. a garage) in accordance with legislative and planning
requirements, environmental standards, and safe work practices.
 describing what is involved in conducting a pre-commencement site
inspection.
1. Read the scenario below that relates to the building of the Casey
house and respond to the questions that follow.
Scenario
Consider the plans for the Casey house and imagine that you are
responsible for planning the building of this house in a bushfire-prone
alpine area: Casey plans – Sections, Elevations, Floor Plan, Site Plan.
As part of the planning process you need to ensure the structures and
materials you use will together withstand the loads and forces that will
act upon them, and ensure the stability of the building.
Outline the main structural principles that might apply to the construction of the
Casey house including forces, loads and mechanical properties of materials
(material fuel loads). Include two examples of each principle that would apply to
the Casey house. (400 words max)
 Loads (include two examples):
1. Dead loads: these are permanent loads that are carried by the structure.
For example; permanent non-load bearing partitions and walls, floor
surfacing materials and built-in fixtures.
2. Live loads: these include the weight of movable objects and fixtures
which are carried by the building structure.
For example; furniture and people
 Forces (include two examples):
Open Colleges
32636/01 Apply structural principles to residential low rise constructions.
Page 6 of 12

1. External forces: These are forces that act on the structure from
outside the structure
For example: Gravitational force- this is the force of gravity that acts
on all structures whose value is 9.7K/Nm
2. Internal forces: These are forces that are caused by one part of the
structure that are acting on other parts of the structure
Example: Compression force due to the weight of the roof on the building or
tension force within the beams.
 Mechanical properties of materials (include two examples):
1. Material fuel loads: This refers to the amount of flammable material
that surrounds a fire. The fuel load is measured by the amount of
available fuel per unit area. Fuel includes the wood and other
flammable materials within the structure.
2. Brittleness: A brittle material is a material that fails suddenly without any
cause for deformation when subjected to a load.
Example: low class concrete or poorly cast-iron trusses
3. Strength: This refers to the capacity of the material to resist failure
caused by loads acting on it. For example, the strength of the concrete
used for construction is determined by dividing the ultimate
compressive load taken by the concrete cube divided by its cross-
sectional area.
It is advisable that all concrete works and steel structures to be used in
construction be tested for their compressive and tensile strength.
3. Review the four Casey plans and consider the structural systems
that will be used in the construction including the footings, floor
system, structural and non-structural walls, roofing and external wall
cladding: Casey plans – Sections, Elevations, Floor Plan, Site Plan.
Remember that you are planning to build the Casey house in a bushfire-prone
alpine area.
Complete the table below outlining the materials and performance
characteristics for each structural system, and where you would seek
expert advice.
An example is provided.

5. Before the construction of the Casey house, consider how you might
go about demolishing any small existing structures such as a garage
and brick fencing. Briefly outline the steps you would take for the
demolition process including the planning, and the environmental
and safety requirements you would need to comply with. (200 words
max)
Hint:
To assist with the work safety requirements, look at the ‘Notification of
demolition work’ form on the Sullivon Constructions website. This form is
used to notify WorkCover of demolition work under the Work Health and
Safety Regulation 2011.
The following steps are advised in accordance with AS 2601; the
demolition of structures: Site analysis, planning, execution,
environmental and safety requirements.
 Site analysis: an analysis of the site will be carried out to
determine the dimensions of the structures to be demolished
(garage and brick fence). In addition, affected vegetation,
services and environmental impact will be assessed.
 Planning: a schedule that contains the program of the works to be
carried out will be prepared. A work plan will be submitted before
ant demolition or striping work.
 Safety requirements: All staff on site will be provided dust-proof
masks and hard huts. All services present through the demolition
area will be protected appropriately. All equipment will be
inspected to ensure they are functioning properly. Emergency
exits shall be determined in the site.
 Environmental requirements: The surrounding immediate
environment will be covered will bulkheads and covers to protect
it from dust. A dust-proof screen will be placed around the area of
demolition to avoid debris from encroaching any adjoining
property.
 Execution: The demolition shall be carried out while observing all
the necessary steps set out in AS 2601 and the requisite safety

and environmental requirements.
6. Once the construction planning and demolition processes are
complete for the Casey house, a pre-commencement site inspection
will need to be conducted. Briefly list the factors that would need to
be checked for this inspection. (200 words max)
 All approved plans are present on site
 There is stable electricity on site.
 There is a stable supply of water adequate for construction
 There is a stocked toilet on site that will service the construction
staff
 A site sign-board is present
 There are car parking arrangements for small cars and loading
areas for the trucks.
 All the contractual agreements have been completed including,
the main contract has been signed, all sub-contracts have been
finalised and the construction dates have been set.
 Waste disposal arrangements have been put in place.
 There are safety requirements for the construction staff and
adjoining premises.
 Check for fire requirements, fire separating walls and precautions.
