PIM (Project Information Model) (PIM)

The Project Information Model (PIM) is the information model for the delivery phase of a built asset: the set of coordinated project information developed and used during design, engineering and construction under ISO 19650. Like any ISO 19650 model it is more than a 3D model — it holds graphical and non-graphical information alike.

It is the delivery-phase counterpart of the asset information model (AIM). The PIM is the project's evolving information container during design and construction; the AIM is the asset's long-term operational one. At project completion, the relevant information from the PIM is handed over to populate the AIM, so the operational model carries what is needed to run the asset.

Across delivery, the PIM supports coordination, design intent, construction planning and the progressive development of information toward handover. It is shaped by the Project Information Requirements (PIR), and its basis is ISO 19650-1 (concepts and principles) and ISO 19650-2 (delivery-phase requirements). In Italian it is the modello informativo di progetto.
