BIM AUSTRALIAN STRATEGY
OF OZ
the initiative focused on the development of an Autodesk Revit MEP template add-in that incorporates Australian Standards, industry practices and the National Construction Code. Having a national template to cover all services improves the efficiency of content workflow. A key concept currently being refined is the development of foundation content models. These form the content within the template and are also the source of manufacturer content. With all manufacturers using the same source model, it then becomes simple for contractors to change one pump manufacturer for another when equipment selection is finalised. The model must support the needs of the construction team, but it does not need to be all things to all stakeholders. One example is the use of software to convert the construction design model into fabrication models that can be used to manufacture ductwork. ‘It is important that designers have real-world
ducting and piping libraries, which use content developed from fabrication libraries to give assurance that a ductwork or pipework design can actually be manufactured,’ says Stannus. Translation software allows the construction
design model to be efficiently converted into a fabrication model suitable for driving the coil lines and plasma cutters in the fabrication shop. Getting the ductwork fabrication workflow functioning effectively requires tight control of standards. Stannus says it has been ‘quite a challenge’. However, since Autodesk’s purchase of MAP software (the firm that produced the industry standard CADduct ductwork fabrication software), the efficiency of the design-to- fabrication workflow has improved dramatically. ‘We can now convert more than 95% of the Revit model into a ductwork fabrication model,’ he says.
The final guiding principle is the development
and adoption of a single nomenclature and product data template for plant, equipment and fittings for use by the entire construction sector. ACMA has set out to improve BIM productivity
through the development and adoption of a detailed schema for disciplines, as well as naming conventions and detailed specifications for each product type, such as axial fans or chillers to

We reviewed COBie and believed it would be very difficult to implement; our drive has been to keep things as simple and efficient as possible’ Warwick Stannus
