In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

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

PURPOSE OF THE UNIT STANDARD 
The qualifying learner is capable of:

Supervising the preparing, placing and finishing of concrete placed under water ensuring all work is carried out in accordance with safety legislative requirements and completed to the required dimensions. Demonstrate knowledge of under water concreting practice.

The contribution to The National Skills Development Strategy is the key developmental interface between learners and new competencies to be achieved.

Learners who master the applied competence described in this unit standard will contribute to the development of a professional community of Civil Engineering Construction Concreting practitioners who are able to effectively supervise work crews responsible for the preparing, placing and finishing of concrete placed under water.

The contribution to socio-economic transformation is that learners will be able to undergo RPL-assessment and thereby receive recognition for previous learning and experience. This in turn will enhance the employability and career prospects of learners employed in this sector. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
The following knowledge, skills attitude and/or equivalent:
NQF level 3 Language and Mathematics

Learners will have demonstrated knowledge and understanding of construction drawings and specifications, techniques for calculating construction quantities and developing work plans, setting out work areas and identifying and describing materials used in civil construction.
