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) or one adjustable parametric object, that
allow designers to spatially model to LOD 300 as well as specify the Air Handling Unit’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 Air Handling Unit 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.
The generic design Air Handling Unit is setup to be fully adjustable, no specific catalogue of sizes is provided due
to the extensive variability of selections available.
3.3 Manufacturer certified content
The virtual build develops the design model into the LOD 400 construction model and typically involves changing
out the design content with manufacturer certified content. Where the manufacturer’s model is BIM-MEPAUS
compliant this should be readily achieved.
Manufacturer’s models are preferably generated from the BIM-MEPAUS Industry Foundation Models (IFM) and
are a single type family that has the Air Handling Unit geometry needed for the virtual build plus the manufacturer
data for the specific Air Handling Unit 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 additional product data as required.
BIM-MEPAUS Specification
Air Handling Units
BIM-MEPAUS Page 4 December 2016
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.
3.4 Commissioned As-Built Model
The commissioned as-built model comprises the construction model updated to reflect any changes made during
the field installation.

Air Handling Units
BIM-MEPAUS Page 5 December 2016
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 and completion schedules must be completed for all components and once the values are defined are
fixed for the life of the component.
It is expected that not all data will be carried in the Revit design or virtual construction 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.

5 AIR HANDLING UNIT SPECIFICATION
The following guidance has been developed through the industry consultation process as particular areas requiring
focus during the completion of the Air Handling Unit quality/performance schedules.
5.1 Air Handling Unit duty selection
Air Handling Unit duty should make appropriate allowances for system leakage and/or system diversity to avoid
issues with motor sizing, Air Handling Unit fan efficiency and system commissioning. The duct leakage calculations
should be based on ASHRAE or SMACNA ductwork surface area based methods.
5.2 Air Handling Unit installation arrangements
Air Handling Unit Installation arrangements are important in the Air Handling Unit selection process, the schedule
should nominate the required Air Handling Unit fan arrangement, coil handing and casing openings.
Air Handling Unit fan arrangements are coded as below, with this parameter selectable in the shared parameters
list of the generic design family.
Handings are always nominated left or right looking in the direction of the airflow.
Casing openings and coil connections are nominated in the shared parameters of the generic design family in
accordance with the surface nomination diagram and Air Handling Unit diagram below.

5.3 Smoke spill applications
Air Handling Unit’s contain several components that are covered under AS 1688.1, designers should familiarize
themselves with these requirements and ensure their design complies with the requirements. Plenums and casings
particularly relating to the construction of Air Handling Unit’s, shall be constructed to comply with the requirements
of AS 1668.1. AS 1668 1998 Part 1 requires
The exposed face of any insulation in equipment plenums, built-up air-handling and proprietary air-handling
plant casings shall have indices not greater than the following as determined in accordance with AS/NZS
1530.3:
a. A spread of flame index 0.
b. A smoke-developed index 3.
Masonry, concrete, metal or metal-faced sandwich construction shall be deemed-to-comply materials for the
purpose of this requirement. Where casings are of metal-faced sandwich construction, all raw edges shall
be covered effectively to ensure that the insulation core is not exposed, inside or outside the casing. Where
necessary, raw edges shall be fitted with edge strips. When located on the airstream side of the casing,
edge strips or gaskets between panels shall comply with the early fire hazard indices nominated above for
exposed insulation.
Where not exposed to the airstream, but otherwise exposed within the building, materials used for edge
strips or gaskets between panels shall have fire hazard properties in accordance with the requirements of
the relevant building regulations.
All gaskets thicker than 3mm between metal faces and all non-metallic edge strips that project over the metal
face of the sandwich panel on the airstream side of the casing shall be completely covered with metal strips.
Note: Metal-faced sandwich constructions is not intended to include foil-faced insulation.
5.4 Air Handling Unit motor selection
Motor IP ratings: Typically IP55 is considered adequate for most applications – higher IP ratings may be warranted
for specialized applications.
Thermistor protection is normally provided for all motors 75kW and over as standard, however for motors under this
size thermistor protection must be specified if required to be fitted.
Motors are generally based on 400V 3 Phase 50Hz 4 pole motor selections due to their lower noise and vibration
levels with the following standard range of motors sizes available:
0.37 2.2 11 37
0.55 4.0 15 45
0.75 5.5 18.5 55
1.1 7.5 22 75
1.5 9.5 30 90
Alternative single phase motors are also typically available up to 1.5kW.
BIM-MEPAUS Specification
Air Handling Units
BIM-MEPAUS Page 10 December 2016
Motor speeds are determined by the number of poles as follows:
5.5 Air Handling Unit coil selection
Coils are a highly configurable component of Air Handling Unit’s and will be selected by the manufacturer to suit the
design duty. There are several important parameters to note for coil selection that influence the geometry of the
Air Handling Unit, connections required and manufacturers selection inputs.
