3 MODELS
3.1 Model workflow
One of the principle aims of BIM-MEPAUS is to enable efficient BIM workflows that see the design model
progressively refined through the design, virtual build and construction process to ultimately deliver a completed
Commissioned As-Built Model.
A key step in this process is the virtual build during which the change-out of the generic design components with
Manufacturer’s Certified Models (MCMs) occurs. These MCMs are able to support a range of construction and
commissioning workflows as well as the asset’s life cycle management post-handover.
The completed construction model generated through the virtual build is then used to drive a range of activities
including site layout, procurement and installation scheduling and tracking.
Once the installation is completed and the systems commissioned, as-built data and project completion information
are used to finalise the Commissioned-As Built Model for handover to the client.
3.2 Generic design content
BIM-MEPAUS generic design families provide a catalogue of sizes (types) that allow designers to spatially model to
LOD 300 as well as specify the transformer’s performance and quality requirements.
The generic design model shared parameters have been developed through industry consultation and are
considered those necessary to schedule the quality and performance requirements for tendering and procurement
purposes.
Design firms with content libraries can pre-populate these transformer design families with their specific quality
specifications in order to minimise repetitive data entry on each use in a project. This approach limits subsequent
scheduling to only those instance based performance parameters that are typically scheduled in specification
equipment schedules.
3.3 Manufacturer certified content
Manufacturer’s models are preferably generated from the BIM-MEPAUS Industry Foundation Models (IFM) and
are a single type family that has the transformer geometry needed for the virtual build plus the manufacturer data
for the specific transformer to be supplied to the project.
BIM-MEPAUS certified manufacturer models are fully interchangeable with the generic design models and provide:
• Accurate geometry
• Performance data
• Full BIM-MEPAUS Revit operability.
Where the data is not able to be provided by the manufacturer in Revit shared parameter format, manufacturer data
should be delivered in Excel format using the BIM-MEPAUS Product Data Templates to allow the data to be efficiently
imported by the specialist trade contractor into their scheduling database or Revit virtual build model.
Microsoft Excel based product data templates are provided for this purpose on the BIM-MEPAUS website under the
specification product templates section. Where required additional fields can be drawn from the shared parameter
schedules in this specification to provide more extensive product data as required.
As the MCM and supporting shared parameter schedule replaces the certified drawings and technical schedules
that have traditionally been provided by manufacturers, the model accuracy should be no less than that provided
by a manufacturer’s certified drawing.
Manufacturer’s certified models should preferably include a link to a pdf or web page providing pre-commissioning
checklists for modellers and shop drawers to facilitate the proper incorporation of the component into the model as
well as providing the pre-commissioning check sheet for the project site team.

4 SHARED PARAMETER SCHEDULING
The shared parameter schema has been developed to effectively support data requirements for design,
procurement and commissioning as well as life cycle asset management. All BIM-MEPAUS plant and equipment
models have the same schedule structure shown below.
• Identity
• BIM Classification
• System Analysis
• Green Building Properties
• Performance / Quality
• Manufacturer
• Commissioning
• Completion
System Analysis, Green Building Properties and Commissioning schedules are only included where applicable or
where they have been defined by a relevant standard.
The schedules are progressively completed as the MEP services model progresses through design and virtual
construction to a fully completed Commissioned As-built component within the final model.
Schedule Section Generic Design / MCM
Model schedule
Schedule completion by
Identity Generic design model Designer / Manufacturer / Installer
BIM Classification Generic design model Designer
System Analysis Generic design model Designer
Green Building Properties Generic design model / MCM model Designer / Installer / Manufacturer
Performance /Quality Generic design model / MCM model Designer / Installer
Manufacturer MCM model Manufacturer
Commissioning MCM model Installer
Completion Schedule MCM model Installer
The identity schedule must be completed for all components and once the values are defined are fixed for the life
of the component.
It is not expected that all data will be carried in the Revit model with non-core data likely to be managed off model
using scheduling databases and/or spreadsheets. This non-core data is commonly required for the finalization of
procurement, commissioning and facility management purposes.
Manufacturer BIM data must be supplied in a format that can be imported into a data management system and/or
Revit based Virtual Construction model with suitable formats including:
• MCM model incorporating BIM-MEPAUS Product Data Template shared parameters
• MCM geometry model with supporting BIM-MEPAUS Product Data Template Excel file.
To allow efficient and reliable data exchanges, it is critical that the BIM-MEPAUS shared parameter names and
respective GUIDs be used.
Parameters indicated in bold font are core Revit model data expected to reside in the model whilst those in italics
are non-core data that can be managed either in the Revit MEP model or off model in a scheduling database.
Parameters notated with the symbol have an industry defined set of allowable values or descriptions that are
listed in the master BIM-MEPAUS shared parameter schedule.
It is noted that BIM-MEPAUS compliant manufacturer’s certified models can be used for the basis of design where deemed appropriate by the designer and/or where specific manufacturer plant and equipment is to be nominated.

5 TRANSFORMER SPECIFICATION
The following guidance has been developed through the industry consultation process as particular areas requiring
focus during the completion of the transformer quality/performance schedules.
5.1 Transformer type classification
The transformer classification schedule is based on the insulation medium and the form of heat rejection.
ANAN – Air Natural Air Natural (air insulated / natural ventilation cooled)
ANAF – Air Natural Air Forced (air insulated / forced draft air cooled)
ONAN – Oil Natural Air Natural (Oil immersed / natural ventilation cooled)
ONAF – Oil Natural Air Forced (Oil immersed / forced draft cooled)
KNAN – Synthetic Oil Air Natural (Synthetic oil immersed / natural ventilation cooled)
KNAF- Synthetic Oil Air Natural (Synthetic oil immersed / forced draft cooled)
5.2 Transformer Selection
For the built environment applications, dry type enclosed naturally ventilated transformers are typically specified to
be provided with HV and LV coils of copper and cast resin construction. Aluminum coils may be used as an
alternative to copper and for LV coils impregnated insulation may be utilized as an alternative to cast resin.
Oil immersed transformers require provision of bunding and blast walls and hence are typically avoided where a
transformer is located within a building.
The majority of transformers supplied in Australia for the built environment have the following core specification
parameters:
Vector Connections : Dyn11
Ambient Class : C2
Environmental Class : E2
Fire Behaviour Class : F1
The temperature rise determines the insulation class with 150oC indicating Class F and 180oC indicating Class H.
Noise criteria are typically based on the kVA rating with the Australian standards providing both standard and
reduced noise level ratings.
5.3 Transformer Sizing
The standard transformer sizes are:
100kVA 750kVA 1600kVA 4000kVA
200kVA 1000kVA 2000kVA 5000kVA
315kVA 1250kVA 2500kVA
500kVA 1500kVA 3000kVA
The majority of transformers for commercial applications would be selected in the 500kVA to 2000kVA range, the
sizes indicated in bold are the sizes provided in the generic family catalogue.

5.4 Transformer Procurement
The procurement of the transformers varies depending on the location and project type with transformers supplied
by the either the energy utility or by the proprietor. In both cases the transformer technical schedule will be required
to complete the power system design.
5.5 IP Ratings
IP ratings for commercial applications located indoors are typically IP 21, whilst for industrial applications IP 41 is
commonly specified to mitigate risks related to dust and moisture.
5.6 Design Life
Nominal design life of transformers is typically between 20-25 years; however it is not uncommon for transformers
to achieve service lives in excess of 40 years. The service life in practice is determined by a range of factors
including loading and number of power surges experienced by the transformer over its life.
5.7 Access and clearance zones
The access requirements and clearance zones will be determined by the supply authority and relevant Australia
Standards.
In transformer rooms with limited space it may be necessary to specify the enclosure doors to be lift off type rather
than hinged.
As transformers are typically heavy it is important to assure that the transformer replacement route has adequate
physical and structural strength to allow the transformer to be moved.

6.7 Family geometry
Family geometry is controlled by instance based parameters with the intention that the modeller should not need to
modify the geometry of generic design models or Manufacturer’s Certified Models.
It is noted that the Family Dimension Parameters are used to schedule those parameters that define the type (size
or capacity), with all detailed geometry dimensions listed separately under the Geometry Grouping.
Critical dimensions in relation to the model geometry are:
• Transformer height, width and depth
• Panel opening size and type (Door size and locations)
• Maintenance Clearance.
• Fixing method
6.8 Clearance and access zones
The required clearance zones are described in Section 5 and are controlled by type based parameters.
These requirements can be turned on or off for the purpose of clash coordination exercises.
