CPCCBC4010B: Assessment 6
What you have to do
Refer to
•
Project 1 and Project 3 on the OLS and
•
the sketching guidelines
to help you complete the questions below.
Sketching guidelines
This assessment contains a number of tasks requiring you to prepare sketches of relevant
construction details. The sketches are to be prepared to a standard acceptable to allow
communication of a detail as would occur on a construction site. Many details are
communicated in this manner and everyone involved with building sites should be skilled in
the preparation of sketches.
Sketches are freehand drawings. Line work and proportion are important considerations that
must be satisfied in the assessment. Select a scale/size appropriate to the detail.
It is not expected everyone will have these skills at the commencement of this assessment.
This first assessment may be presented with a mix of freehand sketches and ruled drawings.
All should be completed in pencil on A4 size paper. Refer to the project documentation
before commencing the drawings to clearly identify and comply with the documents. This
question may require you to carry out research of the topics to broaden your knowledge
before attempting the answers.
Submissions which are assessed to be not of an acceptable standard will be returned with a
request to resubmit the assessment.
Question 1
(refer to Project 3)
Develop a plan to demolish the existing dwelling shown on the site plan in accordance with
the legislative and planning requirements and at all times utilising safe work practices. The
dwelling will have been constructed from some building materials containing bonded
asbestos.
In your plan, list the relevant Acts, Australian Standards and Codes with which the
processes will need to comply.
Note: This is not a sketch, but a set of steps outlining your approach. You might include a
sketch to indicate specific requirements of the demolition process.
Question 2
(refer to Project 3)
From the project documentation, identify the loads the building will be subjected to during its
life. Prepare a simple sketch of a section passing through the centre of the dwelling and
showing the structural elements of the building.

Draw arrows on the section to show the direction the load path will take to transfer the loads
to the foundation of the building. Your illustration(s) should deal with wind loads as well as
dead and live loads.
Question 3
(refer to Project 1)
Research and list the Building Code of Australia requirements for the dwelling to be built
within the following zones:
•
Bushfire (medium risk)
•
High wind
•
Earthquake
•
Alpine area (NSW)
Question 4
(refer to Project 1)
A site inspection is necessary prior to tendering or commencing construction on a project to
assess the natural and developed features of the site which will contribute to the cost and/or
planning of the construction.
Consider the site of the dwelling is vacant and you are intending to tender on the
construction of the building. Create a checklist for a preliminary site inspection of the site
which could be used on future projects. The checklist should be word processed and
incorporate tables where suitable.
Provide a sketch of the site clearly showing salient features such as:
•
vegetation
•
rock features
•
existing services
•
improvements such as fences and existing buildings
•
orientation
•
contours
Question 5
(refer to Project 1)
Prepare a list and description of all the relevant services required or likely to be installed in
and around the building and note any special provisions needed. For each service, list the
Australian Standard or Code with which the service must comply.
Question 6
(refer to Project 1)
Prepare a checklist to ensure the quality of each of the following systems to the building:
2
•
footing
•
floor

Applying structural principles
Structural members are the primary load bearing components of a building. The structure of a building
constitutes about 30% of the construction cost. Good structural design can result in cost efficient building.
The structure of a building is the part which is responsible for maintaining the shape of the building under the
influence of the forces to which it is subjected.
A building must be designed to safely withstand the most severe combination of forces or loads likely to be
applied during its lifetime.
The loads that are to be assumed while designing a structure are usually specified in the ‘loading codes’ (see
Australian Standard AS/NZS 1170).
In Australia we use the unit kilopascals (kPa) to measure stress and pressure, and kilonewtons (kN) to measure
forces and loads.
Note: 1 kPa = 1 kN/m2
Structural Principles – Forces1
In any building design, the strength and stability of an overall building and its individual components must be
considered. This involves structural calculations to work out the effects of all the forces acting on any
component in the building and on the building overall. To do this we need to resolve the forces in the system to
see what the overall effects are likely to be.

Vectors
Forces can be represented by arrows called vectors. Vectors have three properties which enable a force to be
completely represented:
1.Magnitude – how big is the force?
2.Direction – in which direction is the force acting?
3.Position – where on the body does the force act?
Vectors are drawn on graph paper to a suitable scale. All vectors are drawn:
to a length that shows their magnitude
with arrow heads indicating direction and the arrow tail indicating their point of origin.
Note the convention of giving forces a positive or negative value, where forces in and directions are positive
and forces in and directions are negative.
A suitable scale could be 1 mm:1 kN or alternatively 10 mm:100 kN depending on the situation.
Newton’s laws of motion
The unit of force is the newton (N) named after Sir Isaac Newton (1642 – 1727). He observed apples falling from
a tree and realised that the force produced by a falling apple is equal to its mass times the earth’s gravitational
A newton is the force which when applied to a body of mass of 1 kilogram causes an acceleration of 1 metre per
second in the direction in which the force is applied.
The earth’s gravitational pull is approximately 9.81 m/s2 so 1 kg will produce a force of 9.81 N. This figure is
often rounded up to 10 N for ease of use.
1 kg mass produces a force of 10N.

100 kg mass produces a force of 1,000 N.
1,000 kg mass produces a force of 10 kN.
Newton’s second law – A force is caused by an acceleration acting on an object.
The most common form of acceleration is gravity. All objects are pulled towards the earth by gravity. Gravity
acting on a mass produces the effect commonly known as weight which is really a type of force.
Newton’s second law can be written as a mathematical equation.
force = mass x acceleration
f = m x a or f = ma
Force is a push or pull which is applied to an object. Force is measured in newtons (N).
Mass is the mass or weight of the object to which the force is being applied. Mass is measured in kilograms (kg).
Acceleration is any change in the speed or velocity of the object, ie speeding up or slowing down. Acceleration is
measured in metres per second per second (m/s2).
Newton’s third law – Action and reaction are equal and opposite.
For example, a building has a force applied to the corner.
The building is not stable enough to offer any resistance to the resultant force. Structural failure results since the
building is no longer in a state of equilibrium.
The building is now fitted with a diagonal brace or strut. The diagonal brace acts as a reaction force against the
resultant force. The building is now in a state of equilibrium.
