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

GIS Integration

3/24/2015 10

• 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
