PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard will be able to:
Identify and describe the functions of the contracts planning department, describe workshop layout and explain workshop planning and procurement procedures as well as the procedures for handling and preparing steel through the preparation bay. Learners will be able to describe layout, dimensional checks and final assembly operations carried out by workshops responsible for the fabrication of structural steelwork assemblies. In addition, learners will be able to explain construction site procedures for the erection of steel structures. 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 be able to apply their knowledge and understanding of basic contract planning functions, workshop and site procedures for structural steel projects to programme planning and communication processes between drawing office and client thereby ensuring that the time and cost implication associated with the repeated revision of drawings is minimised.
