1 INTRODUCTION
1.1 Scope
These guidelines set out the BIM�MEPAUS
framework for the development and management of Industry
Foundation Models and the BIM�MEPAUS
Master Shared Parameter Schedule.
Industry Foundation Models (IFMs) provide Autodesk®Revit
® MEP plant, equipment and fitting families for
designers and manufacturers. The models are sourced from the Autodesk Australian Content Pack and
incorporate BIM�MEPAUS
Shared Parameters to provide families that can be used for design modelling as well as
the basis for development of Manufacturer’s Certified Models (MCMs).
The BIM�MEPAUS
Master Shared Parameter Schedule is a BIM�MEPAUS
controlled document that lists and
classifies all shared parameters for use in BIM�MEPAUS
model content and workflows related to design,
construction and supply chain integration. The shared parameters also include for facility and asset management
requirements. Use of the shared parameters can extend to off model data applications including a range of BIM�
to�Field construction and commissioning workflows and e�procurement.
1.2 Aims
The use of IFMs and BIM�MEPAUS
Master Shared Parameters provides a number of important benefits to
designers, constructors, manufacturers, facility managers and owners:
• Best�of�Breed MEP content for the Australian building services sector;
• Structured and consistent parameter scheduling that enables the industry to reliably and efficiently
leverage workflows including design scheduling and BIM�to�Field data exchange; and
• Reduced implementation costs.
1.3 Development Approach
BIM�MEPAUS
engaged with industry practitioners to assist the development of the naming convention and shared
parameter strategy.
As far as practicable, the IFMs and shared parameters aim to comply with, in order of precedence:
• Established industry naming conventions;
• Australian & New Zealand Revit Standards (ANZRS);
• Revit MEP shared parameter schema;
Compliance with international standards including:
• ISO 16739:2013 Industry Foundation Classes (IFC) for data sharing in the construction and facility
management industries;
• Construction Operations Building Information Exchange (COBie);
was not always possible. As a consequence, it may be necessary to map BIM�MEPAUS
parameters to these and
other standards as necessary.
Model geometry is based on relevant standards where these exist or has been sourced from supplier data to
develop representative geometries.

2.4 Autodesk Revit MEP
BIM�MEPAUS
utilizes Autodesk Revit MEP as its core BIM authoring platform. The Industry Foundation Models
and BIM�MEPAUS
Master Shared Parameter Schedule are based on the Revit MEP modelling and parameter
organisation.
2.5 Autodesk® Revit MEP® Australian Content Pack
The Autodesk Revit MEP® Australian Content Pack is a library of plant, equipment and fitting families developed
and maintained by Autodesk that comply with Autodesk Revit Content Guidelines.
Included within the families are the Family Parameters needed to control the dimensions and geometry as well as
the functionality of the model together with associated core system and shared parameters.
Content models are purposely lean with respect to geometry whilst still providing sufficient detail to allow
designers and modellers to easily distinguish the different types of plant, equipment and fittings within the model.
2.6 BIM�MEPAUS IFM Generic Design Content
The BIM�MEPAUS
Industry Foundation Model Content takes the Autodesk Australian Content Pack and integrates
the BIM�MEPAUS
Shared Parameter Schedule for each family to provide a comprehensive set of shared
parameters. The generic design IFMs are an integral part of the template and are published through the BIM�
MEPAUS
website.
IFMs provide a sufficient range of Types within the family to meet project spatial planning requirements to LOD
300 requirements as well as the technical schedules typically used by designers and contractors for specification
and procurement scheduling respectively.
2.7 Manufacturer’s Certified Models
Manufacturer’s Certified Models (MCMs) are generally best created from the BIM�MEPAUS
IFMs and comply with
the BIM�MEPAUS
Content Specifications to work seamlessly with the BIM�MEPAUS
Template. To be compliant
with BIM�MEPAUS
, Manufacturer’s Certified Content must be:
• Fully interchangeable with the relevant IFM
• Work seamlessly with the BIM�MEPAUS
Template
• Be complaint with the relevant BIM�MEPAUS
specification and the BIM�MEPAUS
Master Shared
Parameter Schedule including the relevant GUIDs.
MCMs issued by the manufacturer are accurate representations of the physical and functional characteristics of
the product to be supplied to the project; they replace manufacturer’s certified drawings and schedules
traditionally issued by manufacturers.
Manufacturers can use the IFMs to customize the geometry to suit their particular product details and can, if
necessary, modify the family geometry to provide better representation of their particular product whilst working
within the principles of lean content geometry.
The form of the MCM depends on whether it is plant, equipment or fittings. For plant the MCM is a single type with
the relevant technical schedules attached, for equipment the MCM can be a true family of types, but still with fixed
geometry for each type.
For plant such as fans, pumps and air handling units it is expected that manufacturer’s will augment their website
selection software to include content configurators. These content configurators will select the correct type from
the Manufacturer’s pre�built library of product families to which it then adds the relevant technical schedules prior
to publishing.
For equipment and fittings, manufacturer’s can host their MCMs through Design Content delivered via the BIM�
MEPAUS
website and/or have it hosted on their own website.

2.8 BIM�MEPAUS Revit Template
The Revit BIM�MEPAUS
Revit Template provides users with:
• System libraries for ductwork, pipework, electrical cabling and containment built to Australian Standards;
• A range of standard modelling and design views; and
• Interfaces to the BIM�MEPAUS
IFM Content Pack.
The User Guide and Specification for the BIM�MEPAUS
Revit Template is located on the BIM�MEPAUS
website.
2.9 BIM�MEPAUS Master Shared Parameter List
The BIM�MEPAUS
Master Shared Parameter Schedule is hosted on the BIM�MEPAUS
website that lists the Revit
shared parameters used to schedule BIM�MEPAUS
systems, plant, equipment and fittings.
BIM�MEPAUS
Shared parameters are grouped as follows:
• Identity
• BIM Classification
• System Analysis
• Performance / Quality
• Manufacturer
• Green Building Properties
• Commissioning
• Completion
The BIM�MEPAUS
Master Shared Parameter Schedule also details the classification of each shared parameter
within the Autodesk® Revit
® Shared Parameter Schema.

3 SCHEDULING DOCUMENTS
3.1 Scheduling Documents
The scheduling of plant, equipment and fittings is documented through the following combination of documents:
• BIM�MEPAUS
Specifications
• BIM�MEPAUS
IFM Schedules
• BIM�MEPAUS
Master Shared Parameter Schedule
3.2 Specifications
The specifications provide a technical overview of the plant, equipment or fitting together with the shared
parameters and may provide supporting scheduling advice, particularly in relation to industry standard practice
where appropriate.
3.3 BIM�MEPAUS IFM Schedules
Each specific Functional Family Type has a dedicated BIM�MEPAUS
IFM Schedule which is a Microsoft Excel
Document. The document has two components:
• Blue Tabbed – Listing of IFM Families and their Types
• Green Tabbed – CAB Shared Parameter Schedule.
Functional Family Types form the primary level classification for all plant, equipment and fittings. Functional
Family Sub�Types serve to further classify the functional types into specific families – generally with similar
geometries and technical schedules.
To illustrate, for the Functional Type Fans, there are a number of functional sub�types including:
• AdjustablePitchAxial
• AxialPlate
• RoofMountVerticalDischargeCent.
Each of these will then have a specific catalogue of types based on size.
3.4 BIM�MEPAUS Master Shared Parameter List
The master shared parameter list contains the controlled list of shared parameter names and their classification
within the Revit MEP shared parameter classification system.
As further plant and equipment are added to BIM�MEPAUS
, the BIM�MEPAUS
Master Shared Parameter
Schedule will be used to select the relevant shared parameter or, if non have been previously designated for a
specific scheduling requirement, a new parameter name will be added.

4 INDUSTRY FOUNDATION MODELS
Industry Foundation Models (IFMs) provide a set of Revit families that are intended to cover the plant, equipment
and fitting requirements for all services trades.
IFMS are suitable for all levels of model development up to and including LOD 200�LOD300 design modelling.
Manufacturers are also able to utilise the IFMs to generate their specific families and can be used to deliver a
LOD 500 model.
4.1 Model Workflows
Workflows in relation to the Industry Foundation Models, Design and Manufacturer’s content are shown below:

4.2 IFM/MCM Naming Syntax
The naming convention is based on ANZRS syntax, except that the ANZRS pre�fix is not applied due to the
difficulties associated with international supplier content. Syntax is as follows:
IFM: <Functional Type>_< Functional Sub�Type>_<Generic >_<Descriptor>
MCM: <Functional Type>_< Functional Sub�Type>_<Manufacturer>_<Descriptor>
To illustrate the use of this syntax, the Industry Foundation Model for Adjustable Pitch Axial Fans, this is shown
below:
IFM Generic Design Model
Fan_AdjustablePitchAxial_Generic_IFM
Types include:
DIA _1000
DIA_710
DIA _400
Manufacturer Certified Model
Fan_AdjustablePitchAxial_Manufacturer’sName_APS 710
Figure 3.2.1 : IFM and MCM Families
In this case, the MCM model is based on the DIA 710 Type from the Manufacturer’s library of available Types.

4.3 Categories
Each IFM will be generated using the appropriate Family Category that assigns the parameter and functional properties of a predefined family category.
Categories are built into Revit MEP and cannot be redefined by the user: The available categories related to building services families are broadly classified into the following types:
• Equipment: Equipment comprises end of line plant such as chillers, air handling units generators and pumps.
• Devices: End of Line components similar to fixtures that generate inputs into systems and include: nurse call points or thermostats
• Fixtures: End of line components such as air terminals, light fittings, power outlets, sinks, sprinklers, etc that are generally fixed to surfaces.
• Fittings: In�line components that are fitted into piping, ductwork and cabling systems and includes accessories.
Refer to the BIM�MEPAUS
Share Parameter Master Schedule for the listing of Revit categories.

5 REVIT PARAMETER TYPES
Revit classifies parameters into four key types, each type of parameter has a specific purpose and functionality:
• System Parameters
• Project Parameters
• Family Parameters
• Shared Parameters
The following provides an overview of each of these parameter types and their intended use.
5.1 System Parameters
System parameters are built�in to Revit and are embedded into projects and families. They cannot be modified,
added to or deleted by the user.
Revit system parameters include:
Length Dimensions
Width Dimensions
Height Dimensions
Manufacturer Identity Data
Model Identity Data
Description Identity Data
Keynote Identity Data
URL Identity Data
OmniClass Number Identity Data
System parameter values can be shown in tags and schedules.
5.2 Project Parameters
Project Parameters are user defined shared parameters that are added to selected element categories for a
specific project.
An example of the use of Project Parameters is a requirement to identify pre�fabricated components on a project.
There is no parameter within the BIM�MEPAUS
shared parameter scheme for this so a Project Specific Pre�
Fabrication parameter is added to identification schedule to identify components to be delivered through off�site
fabrication:
PreFabComponent Yes/No
The use of project parameters should preferably be kept to a minimum.
5.3 Family Parameters
Family parameters are specific to a Family to which they are added and are generally used to define the family,
particularly with regard to parametric performance and geometry. They do not show in tags or schedules, or other
families of the same category.
Family parameters are set�up in the Family Editor and can be either Type Parameters or Instance Parameters.
BIM�MEPAUS
Industry Foundation Models and Parameter Scheduling Guidelines
BIM�MEPAUS
Page 14
June 2014
5.4 Shared Parameters
Shared Parameters are stored in a “shared parameters” text file and from there they can be loaded into families
as “Type” or “Instance” based parameters or into projects as “Project Parameters”. Shared parameters can be
used in schedules and tags and also to share information with other data bases. They carry the majority of the
data to be exchanged between organizations and/or used for design and BIM�to�Field.
When created, Shared Parameters are given an automatically generated GUID (Global Unique Identifier). They
can be exported to other Shared Parameter files, in which case they will still contain the associated GUID.
Shared Parameter values can be searched, extracted and pushed to a variety of file formats including Excel and
SQL databases.
5.5 Application of Parameters
System Parameters form part of the Revit programme with the Identity Data system parameters primarily used
for content identification and scheduling.
Family Parameters are used within the families and are added via the Family Editor. Family Parameters are
included within IFMs to define geometry and function.
Project Parameters are added via Manage>Settings>Project Parameters. The use of Project Parameters should
generally be kept to a minimum, particularly in design.
Shared Parameters are added to the IFMs as part of the customization of the global content developed by
Autodesk. The Shared Parameter list is developed by BIM�MEPAUS
. The Shared Parameters provided with the
IFMs should generally not be changed, however Project Parameters can be added.

6 PARAMETER CLASSIFICATION
Revit organises shared parameter data through a range of classification fields including
• Discipline
• Type of Parameter
• Parameter Group
The Master Shared Parameter Schedule provides the available fields for each of the above within the Revit
Classification Scheme.
6.1 Disciplines
Revit has a pre�defined discipline structure:
• Structural
• HVAC
• Electrical
• Piping
• Energy
• Common
Revit Disciplines provide the principal means of organising views within the model.
The Common Discipline is used for those parameter types that are used across all categories.
6.2 Type of Parameter
Type of Parameter defines the type of parameter ie Airflow, etc .
The available range of Revit Type of Parameter are determined by the Revit Discipline selected; selecting HVAC for instance will allow selection of Airflow, Resistance, etc.
6.3 Parameter Group
Parameter Group defines grouping within each of the disciplines and are used to organise the display of shared parameters into logical groups.
Within Revit it is possible to create Parameter Groups and BIM�MEPAUS
grouping incorporates both established groups as well as a number of new groups which help organise information into logical groups which support progressive development of the data sets.
The core parameter groups are reflected in the Master Shared Parameter Structure and include:
• Identity
• BIM Classification
• System Analysis
• Green Building Properties
• Performance / Quality
• Manufacturer
• Commissioning
• Completion
Plus
• Constraints
• Dimensions
• Geometry
• Visibility

7 SHARED PARAMETER SCHEME
There are a number of published shared parameter schedules currently in use, each with their own classification
schemes used to organize the parameters:
7.1 Industry Schemes
The two most common industry schemes are:
• Autodesk Master Shared Parameter List
• ANZRS Master Shared Parameter List
Autodesk’s Classification Scheme is as follows:
Category: Mechanical Equipment
Part Type: Air Conditioners – Packaged Rooftop
Parameter Name: Total Heating Capacity
Parameter Group: Mechanical Airflow
Parameter Type: Shared Parameter
GUID: 78ce3�aba8�4570�a7d7�038e46cd3b71
Discipline: HVAC
Type of Parameter: Air Flow
Australia & New Zealand’s Scheme is as follows:
Category: Mechanical Equipment
Parameter Group: Mechanical � Airflow
Parameter Name: TotalHeatingCapacity_ANZRS
GUID: 78ce3�aba8�4570�a7d7�038e46cd3b71
Discipline: HVAC
Type of Parameter: Airflow
7.2 BIM�MEPAUS Scheme
The scheme used by BIM�MEPAUS
is based on grouping similar parameters rather than the category. In this way the list is kept relatively small as the same parameters may be used by a number of plant, equipment and fitting items. The parameters required for each component are listed in the relevant specification and draw from the master shared parameter list. Based on the above strategy, the schemes the scheme for BIM�MEP
AUS would be as follows:
Parameter Group: Performance Quality
Parameter Name: FanAirFlow
Units: L/s
Discipline HVAC
Type of Parameter AirFlow
GUID 78ba3�rta8�4680�m4d8�218e74mm3b26

8 PARAMETER NAMING CONVENTION
8.1 Introduction
The BIM�MEPAUS
parameter naming convention generally aligns Autodesk, ANZRS, IFC and COBie guidelines,
noting that these are not cohesive and/or sufficient to meet the requirements of the BIM�MEPAUS
integrated
workflows.
8.2 Syntax
CamelCase format has been adopted to align with ANZRS and Ifc practice. The use of CamelCase is preferred as
it significantly improves the reliability of parameter names by database applications.
The following conventions are incorporated in the shared parameter naming convention
• Use of CamelCase
• No spaces in the naming string
• Units of measure are not included in the parameter name
• Country and Standards Prefix/suffixes are not included in the names
• Mathematical operators in the naming string are not permitted:
• Plus ‘+’,
• Minus ‘�‘
• Divide ‘/’
• Multiply ‘*’
• Hash ‘#’
• Carat ‘^’
8.3 Parameter Naming Conventions
The parameter naming conventions are defined in the Naming Convention and Units of Measure Guidelines.
In general, the naming convention follows in order of hierarchy:
• Industry naming conventions
• Ifc parameter names
The following key principles apply:
• Xxxxx indicates a Design Parameter such as SupplyAirTemperature;
• XxxxFitted indicates the requirement for a standard option on a component;
• XxxxxCal indicates a Revit calculated value; and
• XxxxxActual indicates a final commissioning result or measured value.

9 MASTER SHARED PARAMETER SCHEDULE
9.1 Schedule Overview
The Master Shared Parameter Schedule is an Excel based BIM�MEPAUS
Master Shared Parameter Schedule
which is used to manage the Shared Parameter Master List. An individual Workbook is provided for each
discipline.
Tables are provided for each Design/Trade Discipline with secondary classification of the parameters organized
by the following Shared Parameter Grouping
• Identity
• BIM Classification
• System Analysis
• Green Building Properties
• Performance / Quality
• Manufacturer
• Commissioning
• Completion
This grouping is organized by workflow requirements rather than traditional Revit classifications structures. The
Identity, BIM Classification and Completion Schedules are common across all Design/Trade disciplines.
An additional parameter grouping, Engineering, is provided in the BIM�MEPAUS
Master Shared Parameter
Schedule that augments the Performance/Quality Schedule. This schedule lists quality/performance and
engineering parameters used across multiple disciplines such as Sound Power Levels, Electric Motors, Power
Supplies, etc. In most cases, these are assigned as Common Revit Discipline.
9.2 Schedule Management
Requests for additional parameters can be made through the BIM�MEPAUS
website template update page.
Updates and revisions will be issued quarterly and list of proposed revisions and updates will be hosted on the
BIM�MEPAUS
website.
Included within the BIM�MEPAUS
Master Shared Parameter Schedule is the revision number for each parameter
and a table which lists the revision number to a specific release date.
Version 6 is the first official release via the BIM�MEPAUS

9.3 Non BIM�MEPAUS Shared Parameters
In general, these should be kept to an absolute minimum.
Project Shared Parameters and Company Specific non BIM�MEPAUS
Shared Parameters can be added to families
however where a defined parameter exists for variable this must be used noteing that the supply chain relies on
consistent variable naming to operate reliably.
9.4 Shared Parameter File
The Share Parameter file itself is a text file and this file will be issued along with the template file when
downloaded by BIM�MEPAUS
subscribers.
The shared Parameters get loaded into the Template file and then assigned to the applicable Revit categories.
In addition to loading these shared parameters into the BIM�MEPAUS
Template, the parameters will also be
loaded into the BIM�MEPAUS
Foundation Models so that that even when the BIM�MEPAUS
Template is not being
used it will still be able to produce these type of schedules from the IFMs.
