Description
This unit specifies the skills and knowledge required to concrete simple forms and excavations in an underwater environment.It includes preparing for underwater concreting, constructing simple formwork, and positioning reinforcement rods and fixed anchorages. It also includes pouring and screeding the concrete to the required finish, recovering formwork and waste, and deservicing and storing tools.This unit relates, in part, to existing standards in the Australian Diver Accreditation Scheme (ADAS).This unit applies to persons working as Defence Divers, but is applicable to other people in this field.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Persons undertaking this unit work independently and perform specific tasks in a range of contexts that could be unpredictable.No licensing, legislative or certification requirements apply to this unit at the time of publication.
