What is building information modelling?

Building Information Modelling (BIM) is a 3D model-based digital design and documentation process that gives AEC professionals the ability to coordinate, construct and manage buildings more efficiently. BIM allows more efficient and effective communication via access to and sharing of information.

Building information modelling (BIM) is predicated on the idea that a building should be constructed twice: virtually first, physically second.

Exactly what benefits can be expected from BIM projects?

  • Improvements in firm productivity;
  • Improved workplace practices / reduced onsite conflict;
  • Reduction in reworks and material wastes;
  • Better health and safety in design and performance;
  • Reduced costs;
  • Environmentally sustainable design and operations;
  • Reduction in schedule overruns;
  • Improved building operability and energy efficiency;
  • Cost reductions and improvements in competitiveness; and
  • Improved business to business relationships.

How do standards help achieve these goals?

To facilitate the efficient exchange of design models and information, data must be standardised to ensure:

  • Efficient and effective communication via access to and sharing of information
  • Consistent and repeatable representation of the physical, functional and spatial characteristics of a building or facility
  • Learnings and best practices are passed on / shared
  • Minimum performance and quality requirements, including Safety and Environmental aspects
  • Interoperability between organisations and disciplines
  • Simplified maintenance of assets


BIM-MEPAUS is a national ‘standard practice’ for BIM – specifically focusing on MEP services throughout the design process and operation of a building.

The success of the BIM process depends on a deliberate and structured approach to the creation and maintenance of digital information. Standardisation of pre-defined parametric data fields ensures that information about a building structure, plant, equipment and fittings is precise enough to accurately represent the physical, spatial and performance characteristics of a building.

The standardisation of data also enables practices and workflows to be developed to ensure that information is shared and applied routinely and consistently throughout the entire construction process, whilst maintaining the integrity of the design.

BIM-MEPAUS develops best practice virtual design to physical construction BIM MEP standards, for the Australian construction and building services industry through:

  • A structured and consistent approach to modelling practices and data management
  • Reliable and accurate Design to Commission As-Built and Design to Fabrication workflows
  • Industry standardization delivering improved supply chain integration and efficiency

Exactly what does BIM-MEPAUS produce?


BIM-MEPAUS aims to publish a set of standards to ensure BIM design models are precise and accurate, practices are applied routinely and consistently, and the sharing of information follows a predictable workflow that provides all parties to a project with confidence in the integrity of both the model and the process.

BIM-MEPAUS standards include:

  • Workflows
  • Guideline documents
  • Specifications for plant, equipment and fittings;
  • Models


BIM-MEPAUS workflows promote the efficient transfer of building information throughout the project lifecycle.  BIM-MEPAUS workflows achieve this by providing a clear pathway for the transfer of BIM models through:

  • Design to Commission As-Built workflow
  • Design to Fabrication workflow
  • Integrated Scheduling database workflow


BIM-MEPAUS guidelines provide a compendium of information or series of options to support the use of other BIM-MEPAUS standards including specifications, practices and workflows.


Specifications detail explicit sets of requirements to be satisfied by a design model of plant, equipment and fittings. Specifications will include requirements for the physical and mechanical properties of both the design and manufacturer models to be used within the Revit MEP software.


BIM-MEPAUS models are the three-dimension representation of the various physical, functional and spatial characteristics (specifications) of a particular piece of plant, equipment or fitting. These models have been designed in consultation with designers, manufacturers and suppliers to ensure the defined parameters are consistent in terms of design and application.
