BIM-MEPAUS is a global leading national industry initiative that develops best practice virtual design to physical construction BIM MEP standards, for the Australian construction and building services industry. This is achieved 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
What is building information modelling?
Building information modelling (BIM) is predicated on the idea that a building should be constructed twice: virtually first, physically second.
This requires a systematic process that enables the capture, recording, exchange and application of building and construction data using detailed three-dimensional modelling.
The success of the 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 functional 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.
Why is building information modelling so innovative?
Building design and construction is inherently a work in progress. As the building transitions from the architectural design model to the building services design model to the constructible model, changes to the overall physical, spatial and functional characteristics of the building are to be expected. Building information modelling allows these changes to be communicated among the key parties to a project during the design phase.
Earlier identification of issues, before they reach the construction process begins, facilitates better service coordination onsite with significant improvements in productivity, cost control and building performance.
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 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 does BIM-MEPAUS help achieve these goals?
To facilitate the exchange of design models and information, data must be standardised to ensure that it is representative of the physical, functional and spatial characteristics of a facility. The creation of a common set of protocols – standards, specifications, practices, models and workflow guidelines – ensures, not only that the data can be trusted, but that it can be continuously shared between all parties to a projects whilst maintaining the integrity of the model and design.
It is these challenges that the BIM-MEPAUS initiative seeks to address.
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:
- Specifications for plant, equipment and fittings;
- Work practices (for example, standard operating procedures);
- Guideline documents; and
BIM-MEPAUS practices will provide documented instructions for the performance of particular operations and functions throughout the BIM design process and workflow.
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 guidelines provide a compendium of information or series of options to support the use of other BIM-MEPAUS standards such as specifications, practices and workflows.
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 design in consultation with designers, manufacturers and suppliers to ensure the defined parameters are consistent in terms of design and application.
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:
- Design model –> Manufacturer model –> Constructible model –> Commissioned as-built model
