This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
People who are pursuing a career in mechanical handling (rigging) require the skills, values and knowledge reflected in this unit standard. Learners who achieve this unit standard will demonstrate a fundamental knowledge of mechanical handling and contribute to their organisations by undertaking to evaluate the logistic, legislative, regulations and client requirements with respect to mechanical handling projects.

A person credited with this unit standard is able to:
  • Determine the necessity and establish the criteria for undertaking a pre-engineering study.
  • Identify the elements and considerations required in a pre-engineering study.
  • Conduct the pre-engineering study of a rigging project.

    This unit standard will contribute to the full development of any learner by providing recognition, further mobility and transportability within the field mechanical handling (rigging) on a processing plant, building or factory installation. The knowledge, skills and understanding demonstrated in this unit standard are essential for social and economic transformation and upliftment within the broader engineering environment.

    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Notes to Assessors:

    Assessors should keep the following general principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes. Do not focus the assessment activities on each assessment criterion. Ensure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • Ensure evidence is gathered across the range as expressed under the title of unit standards. Specific range statements under individual outcomes or assessment criteria are illustrations, from which learning programme developers can select. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the learner is able to perform in the real situation.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance can be reproduced.
  • All assessments should be conducted in line with the following well-documented principles: assessment should be appropriate, fair, manageable, integrated into work or learning, valid, and consistent. Evidence should be authentic, sufficient, and current.
  • Assessment of this standard can be carried out through continuous assessment throughout the course of study and specific performances assessed.
  • Embedded knowledge must be integrated with the Specific Outcomes of the Unit Standard and Critical Cross Field Outcomes.

    Recognition of Prior Learning:

    Credits may be obtained by applying to an accredited/approved training provider/institution in order to have prior learning recognised in lieu of past work experience. Past experience must relate to the specific outcomes contained within this unit standard. The ensuing assessment of candidates seeking recognition of prior learning should not be so onerous as to deter them from doing so.
