Precinct Information Modelling technical investigations: precinct information schema

19 Dec 2016
Description

This technical investigation presents the precinct information (PIM) data schema. The schema is an extension of the current IFC data schema that is used widely for building works. Apart from buildings, precincts also contain infrastructure objects such as roads, railways, bridges, tunnels, and outdoor civic spaces that contribute to the overall carbon impact and therefore need to be modelled. 
PIM considers buildings and infrastructure equally as “built facilities”. Additionally, PIM provides a means to model vegetation that will allow for mitigation factors to be determined when assessing urban heat island effects. The proposed extensions to IFC are defined in a way that generalizes, but does not break, existing IFC functionality.
