Produce an Engineering Design for a Reinforced Concrete Structure
This unit of competency sets out the knowledge and skills required to complete an engineering project brief, including the analysis and design of flexural reinforced concrete members from first principles, using appropriate design aids. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
This unit contains employability skills.
Application of the Unit
This unit of competency is intended to apply to any recognized development program that leads to the acquisition of a formal award at AQF level 6 or higher. This applies in a civil engineering environment where design of reinforced concrete structures is undertaken.
Elements describe the essential outcomes of a unit of competency. Elements describe actions or outcomes that are demonstrable and assessable.
Performance criteria describe the required performance needed to demonstrate achievement of the element – they identify the standard for the element. Where bold / italicized text is used, further information or explanation is detailed in the required skills and knowledge and/or the range statement.
Assessment of performance is to be consistent with the evidence guide.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the associated performance criteria, including required skills and knowledge, and to be capable of applying the competency in new and different situations and contexts within the timeframes typically expected of the discipline, work function and industrial environment.
Specifically they must be able to:
· Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the performance criteria and range
· Demonstrate the required knowledge and skills as described in this unit;
· Demonstrate a representative body of performance criteria within a timeframe typically expected of the discipline, work function and industrial environment;
· Demonstrate the ability to apply principles of design for an engineering sewerage reticulation scheme using appropriate design standards.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations.
The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
Resources required for assessment include:
· OH&S policy and work procedures and instructions.
· Access to workplace or work real environment and a variety of conditions
· Operational access to relevant machines, tools, materials and consumables
· Access to relevant Australian Standards, plans, drawings and instructions and manufacturer’s specifications / manuals
Methods of assessment
For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance.
Evidence must involve demonstration of practical skills and may also include:
· Observation of processes and procedures
· Oral and / or written questioning on required knowledge and skills
· Testimony from supervisors, colleagues, clients and / or other appropriate persons
· Inspection of the final product or outcome
· A portfolio of documentary evidence.
Where performance is not directly observed and/or is required to be demonstrated over a period of time and/or in a number of locations, any evidence should be authenticated by colleagues, supervisors, clients or other appropriate persons.
Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
