Prepare detailed design of urban roads

ASSESSMENT PROJECT

Task Summary:
This assessment task requires the student to prepare detailed designs of urban roads in civil construction on two (2) occasions. This includes:
• Carrying out risk assessments
• Evaluating design options for urban roads
• Interpreting and analysing data and performing calculations to determine the design of the urban roads.
• Preparing design plans for urban roads
• Preparing cost estimates
• Obtaining design approval
• Participating in performance reviews of design processes
• Providing clarification and advice to personnel implementing the design
• Maintaining design and cost records
• Validating designs.
To do so, you will be required to complete the following activities:
• Activity 1: Plan and prepare for the detailed design of urban roads
• Activity 2: Prepare detailed designs of urban roads
• Activity 3: Finalise design processes of urban roads
• Activity 4: Validate designs
All meetings and other skill demonstration activities must be conducted at the ATCWA simulated workplace that replicates a replicate construction workplace conditions and standards, materials, activities, responsibilities, procedures, safety requirements and environmental considerations to each student for the purpose of this assessment.
Resources Required:
• Access to ATCWA Simulated workplace for conducting meeting and consultation sessions
• Access to computers with the internet set -up
• ATCWA Learner assessment instructions manual
• Your learning resources and other information for reference
• Assessment task sheet/Project (This document)
• Project specifications
• Contractual requirements
• Client's requirements
• Project site geological data
• Project site hydrological data
• Project site engineering survey data
• Project site cultural and heritage constraints
• Existing project design and drawings
• Australian or other relevant standards
• Known and potential hazards, constraints and conditions
• Cultural and heritage data
• Meteorological data
Software required:
• Computer aided drafting design (CADD) and drafting technology

Assessment Outcome:
To be deemed satisfactory in this assessment task, you must satisfactorily complete all the tasks under each stage of the project. If the outcome of this assessment is unsatisfactory, you will be guided to conduct re-assessment as per the ATCWA Assessment policy and procedures.

Assessment 2- Project

Project Overview: Banksia link Road Case Study
Scenario:
The following task is to be demonstrated and assessed in the context of the urban road construction sector's work environment. This includes compliance with relevant legislation and regulations, using policies, procedures, processes, and operational manuals directly related to this industry. The outcomes of this project, which occur in an office-based setting, may be assessed in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector's workplace performance, including environment, task skills, task management skills, contingency management skills, and job role environment skills.
Task:

You are tasked with preparing a detailed design of Banksia link Road on two separate occasions. This urban road is a major access lower-speed local urban road with a design speed of 60 km/h. The road will serve both motorists and cyclists, providing access to adjoining properties and several minor access roads. The initial traffic volumes are expected to be between 400 to 450 vehicles per day, growing to no more than 500 vehicles per day over the next 30 years. The guidelines for urban roads provided by AustRoads should be used for this design.
Key Information:
• Project Type: New Construction
• Area Type: Perth Metropolitan Area, Western Australia
• Functional Classification: Lower speed, Local Urban Major access road
• Design Speed: 60 km/h
• Design Traffic Volume: 500 vehicles per day
• Suggested Design Life: 30 years
Assumptions:
• No site-specific safety problems
• Slight evidence of old trees along the intersections
• Lateral Friction Coefficient (f) = 0.20
• Radius of the curve = 100 m
• Cross fall of the road is 1 in 70 and area available for construction 14 m
Occasions:

Occasion 1:
Design Banksia Clink Road considering the following parameters:
• Cross-slope
• Horizontal Alignment
• Superelevation Rate (e)
• Stopping Sight Distance (SSD)
• Design of extra widening
• Intermediate Sight Distance

Occasion 2:
Design the same road considering these parameters:
• Horizontal Curve Radius
• Design of transition Curves

Report Format:
Complete this design in a report format covering/answering the following questions:

1. Compliance and Documentation:
• Access and interpret urban road design documentation, relevant legislation, policies, and procedures.
• Ensure the work activity is compliant with these documents.

2. Work Requirements:
• Access, read, interpret, clarify, confirm, and record the work requirements, including:
• Drawings, specifications, and design briefs
• Engineering survey and geotechnical information
• Hydrological, meteorological, cultural, and heritage data
• Urban roads construction materials test results
• Urban roads selection data
• Determine and record the urban roads capacity requirements.

3. Project Requirements:
• Identify, note, and confirm the urban roads project requirements and information.

4. Design Plan:
• Prepare a design plan making the best use of available resources and meeting the design requirements.

5. Detailed Design Process:
• Interpret and analyse relevant data to identify viable design options and recommend the preferred option.
• Document data analysis, viable options, and the preferred option.
• Use CADD and drafting technology, applying engineering graphical presentation techniques for the detailed design.
• Include calculation of areas, volumes, densities, mass, percentages, and grades.
• Size urban roads components.
• Suggest appropriate construction techniques.
• Participate in the review of the urban roads design with peers and stakeholders.
• Complete required documentation for the urban roads design.
• Monitor and coordinate the progress of team members involved in the design process.
• Gain approval for the design and provide a copy of the written approval.
• Prepare a cost estimate for executing the designed urban roads.

6. Finalisation of Design Process:
• Ensure the filing of design records.
• Submit the design cost and other reporting.
• Participate in a performance review of the design process.
• Seek client feedback and contribute to the verification of the design.
• Provide any client feedback and design verification.
• Prepare a closure document.
