Aim
This unit is about obtaining and verifying dimensional control information, selecting techniques and equipment, setting out
activities and ensuring accuracy of the work. You will need to obtain, collate and verify relevant information and using appropriate techniques and equipment, set out as required, recording information needed for later use. You will need to supply the workforce with dimensional control information, ensure that the results of setting out activities are accurate and also identify and deal with deviations. You will need to check and maintain equipment as specified by manufacturers.
