NOTE TO STUDENTS
These instructions must be followed when doing the assessment in this unit.
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian standards' requirements.
Resource implications for assessment include:
an induction procedure and requirement
realistic tasks or simulated tasks covering the mandatory task requirements
relevant specifications and work instructions
tools and equipment appropriate to applying safe work practices
support materials appropriate to activity
workplace instructions relating to safe work practices and addressing hazards and emergencies
material safety data sheets
research resources, including industry-related systems information.
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources and the provision of appropriate assessment support.
What happens if your result is Not Yet Competent for one or more assessment tasks?
The assessment process is designed to answer the question has the participant satisfactorily demonstrated competence yet? If the answer is Not yet, then we work with you to see how we can get there.
In the case that one or more of your assessments has been marked NYC, your Trainer will provide you with the necessary feedback and guidance, in order for you to resubmit/redo your assessment task(s).
What if you disagree on the assessment outcome?
You can appeal against a decision made in regards to an assessment of your competency. An appeal should only be made if you have been assessed as Not Yet Competent against specific competency standards and you feel you have sufficient grounds to believe that you are entitled to be assessed as competent.
You must be able to adequately demonstrate that you have the skills and experience to be able to meet the requirements of the unit you are appealing against the assessment of.
You can request a form to make an appeal and submit it to your Trainer, the Course Coordinator, or an Administration Officer. The RTO will examine the appeal and you will be advised of the outcome within 14 days. Any additional information you wish to provide may be attached to the form.
What if I believe I am already competent before training?
If you believe you already have the knowledge and skills to be able to demonstrate competence in this unit, speak with your Trainer, as you may be able to apply for Recognition of Prior Learning (RPL).

Task 1
For the proposed residential blocks, as per Appendix I & II, identify the size and the cost of installing soakwell for each block. Include your answer in the Bill of Quantity table allocated in the answer sheet.
Bulk excavation cost $ 25 per cubic meter.
Backfill cost: $35 per cubic meter.
900x900 Diameter Soakwell:$800
1200x1200 Diameter Soakwell:$1000
1200x1500 Diameter Soakwell:$1200
1800x1800 Diameter Soakwell: $1600
1800x600 Diameter Soakwell : $1100
Task 2
For the proposed residential blocks, as per Appendix I, the stormwater will be collected by a civil drain system (Cementous pipes) that connects the subdivisions surface water to the sea in one kilometer.
Two types of materials for the storm drain system are proposed at the design stage, including steel and PVC.
The depth of trenches varies based on the type of material. The design specifications determined the depths of steel and PVC 0.9 m and 1.2 m, respectively. The widths for both types are the same (0.7 m). The required trench for the civil drain system is 1.5 m wide and 1.8 m deep. Propose a cost-effective design. Include your answer in the Bill of Quantity table allocated in the answer sheet.Discharge pit in a cost of $150
Cementous Manholes should be placed every 250 m in a cost $150 each.
900 mm Cementous pipes: $85 per meter
PVC T junction: $ 25
PVC cross intersection $ 45
Steel T junction$ 45
Steel cross intersection $ 75
600 mm PVC pipe:$35 per meter
600 mm steel pipe: $ 50
Bulk excavation cost: $ 25 per cubic meter
Backfill cost: $35 per cubic meter
Task 3
Identify any 5 potential risks at the design and construction stages each and assess them using the risk matrix below. Include your answer in the allocated table in the answer sheet.
Task 4
Imagine that the subdivision is handed over for the construction. List at least 10 equipment and machineries along with their functions. Include your answers in the allocated table in the answer sheet.
Task 5
Provide a work breakdown structure showing the tasks in construction process to the project close out along with a brief of each stage. Include your answers in the allocated table in in the answer sheet.
Task 6
If the catchment area is 210 ha (2.10 km2). An ARI of 5 years was adopted. Calculate the peak charge if the runoff coefficient C is 0.325
