Our purpose is to lower the carbon emissions of the built
environment
while driving the competitive
advantage for Australian industry.
Our mission is to engage in
collaborative research that provides
social and technology solutions and
policy evidence, to capture community imagination and
facilitate the transition
to a lower carbon built environment.

Precinct Information Modelling
A Precinct Information Model (PIM) is a
comprehensive 3D digital database Model of a
Precinct that contains all the Information needed to
support planning, design, development, construction,
management, operation, use and retro-fitting of
urban precincts.
From our perspective as a CRC, the focus is directed
towards minimisation of carbon throughout the
precinct life cycle, supported by a PIM. In a broader
context, a PIM could be used for a whole range of
other purposes.

PIM for Low Carbon Management - How?
Open standardised approach
To defining how we represent/model
the built & natural environment
At urban precinct scale
To facilitate integrated solutions
through smooth information flows

PIM for Low Carbon Management – Lifecycle Approach
As managed
PIM provides a definitive repository of information at all stages in
PRECINCT design & management based on open standards

• A precinct is made up of sites that contain one or more built facilities
• Sites are linked to legal ownership through the cadastre: – Need for a 3D cadastre
• Built facilities include a range of entities: – Buildings
– Civil infrastructure (roads, railway, bridges, tunnels, etc.)
– Utility infrastructure (energy, water, waste, network, etc.)
– Open space (paved, parkland, water features, etc.)
– Structures (street furniture, shelters, public art, etc.)
• Precincts exist within an urban context: – Administrative zones (local government, census, etc.)
– Services (transport, entertainment, education, health, etc.)
Precinct Model Scope
3/24/2015 11
• PIM/BIM uses objects & relationships – Extending from buildings to infrastructure
• Object types & classification systems – role of the data dictionary for classification
• Mechanism for linking concepts across systems
• IFC schema structure – Separate spatial & elemental hierarchies
– Systems: distribution, structural, transport, etc.
– Grouping objects & aggregation
– Control & process concepts
• Mapping concepts between built environment and geographic information systems
