People – Process – Technology are traditionally considered the cornerstones of BIM. That said, without a robust ontology BIM is virtually impossible. Life-cycle management of the built environment is not mainstream due to the following factors.
– Need for a a consistent set of terms and definitions as well as associations. A BIM Ontology enables collaboration and cost effective information creation and ongoing reuse.
– Collaborative construction delivery methods vs. ad hoc antagonistic methods such as design-bid-built.
– Focus upon life-cycle cost vs. first-costs.
