Description
This unit specifies the skills and knowledge required to design complex cold water distribution systems in commercial and high-rise mixed development building to a minimum of 29 floors inclusive of a basement. The unit requires application of technical skills and knowledge to design and size systems and prepare operational and compliance documentation. The role may involve interaction with architects, builders, suppliers, clients and relevant planning authorities and requires a sound understanding of applicable legislation, standards and codes.This unit requirements are typically carried out by a consultant or design engineer. Application of the unit is relevant to multi-storey residential, commercial and industrial buildings with or without connection to reticulated water supply.In some jurisdictions, this unit of competency may form part of accreditation, licensing, legislative, regulatory or certification requirements.
