1 PIM Precinct Information Modelling Information Modelling at a Precinct Scale to Manage the Carbon Load of the Built Environment UNSW: Jim Plume John Mitchell David Marchant UniMelb: Tuan Ngo Oliver Lade Brandon Lim March 2015

2 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. 24/03/2015 2

3 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.

7 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 3/24/2015 7

8 PIM for Low Carbon Management Lifecycle Approach PIM provides a definitive repository of information at all stages in PRECINCT design & management based on open standards Recording needs, aspirations and rating targets Testing scenarios Performance measurement and simulation Construction Management Monitoring and control systems As required As planned As designed As constructed As managed 3/24/2015 8

9 PIM for Low Carbon Management - What? An object-based data model/schema Use-case implementations (proof of concept deliverables) GIS Integration 3/24/2015 9

10 Precinct Model Scope 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.) 3/24/

11 PIM Integration with GIS models 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 3/24/
