TASK ASSESSMENT QUESTIONS

RIICWD509E Prepare Detailed Design of Urban Roads

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).

Credit Transfer

Credit transfer is recognition for study you have already completed. To receive Credit Transfer, you must be enrolled in the relevant program. Credit Transfer can be granted if you provide the RTO with certified copies of your qualifications, a Statement of Attainment or a Statement of Results along with Credit Transfer Application Form. (For further information please visit Credit Transfer Policy.

Activity 1

Compare three (3) Viable options for design of an intersection in an urban road.

Activity 2

This activity aims to provide students with a well-rounded understanding of planning and preparing for the detailed design of urban roads, while also allowing them to develop practical skills and engage in hands-on learning experiences.

Imagine that you are a technician who need to do some desk studies and share your findings with the design team. Analyse traffic flow patterns in the provided (Refer to Appendix 1&2&3) urban areas and fill out the given table.

Note:

You need to go to the Main Road website (https://portal-mainroads.opendata.arcgis.com/) Road information mapping section and find Road Hierarchy, then use Appendix 2 Road hierarchy to find indicative Traffic Volume.

Activity 3:

Risk assessment is an essential part in the road projects. Identify at least five risks at the design stage and complete the risk assessment by using the following risk matrix.

Activity 4

1. Propose two alternative pavement options for one of the given intersections and explain the advantages and disadvantages of each alternative."
2. Provide a sketch (By hand or CAD drawing) of the road cross-section.

Note: the cad drawing file should be included in your submission

Activity 5

Estimate the required materials for the given cross section of flexible road with one kilometre length and 3.5 metre width at the surface base and base layers. The road has 15 cm, 20 cm, and 25 cm thicknesses for surface layer, base layer, and subbase layer, respectively, as shown in Figure. Assume 30% extra material in each layer for fully compaction.

(Hint: the subgrade construction includes site clearance only in this project. There is no embankment at this stage.)

Activity 6

As a civil technician working on a road design project, you need to determine the rate of super elevation in % (e) for a curved road to ensure the safety of drivers by Using the formula: e + f = v²/ (127R).

The road curve has the following specifications:

• Design speed (v): 30.55 m/s.
• Friction factor (f): 0.15
• Radius of the curve (R): 500 meters
