This unit of competency specifies the outcomes required to develop three-dimensional (3-D) models of small-scale building design projects covered by the Building Code of Australia (BCA), except construction Type A buildings, into true building information models (BIM). It involves adding and adjusting values of components of building designs, communicating and collaborating with consultants and contractors from other disciplines involved in construction life cycle of small-scale building design projects, working live within the model alongside other disciplines, and creating project documentation using modelling software programs.The unit supports the work of building information models for small-scale building design projects involving alterations and additions, heritage restorations, and new buildings, including houses, factories, motels, offices, restaurants, retail and service outlets, and warehouses. It applies to building designers who create and use BIMs to optimise productivity and enhance streamlining of the construction process.Licensing, legislative, regulatory or certification requirements apply to this unit of competency in some States. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
