Building information modeling (BIM) describes 3D, object-oriented, AEC-specific CAD: a digital representation of the building process to facilitate exchange and interoperability of information in digital format. BIM covers geometry, spatial relationships, geographic information, quantities and properties of building components. It can therefore be used to demonstrate not only the entire building lifecycle, but also the impacts it can have on the surrounding environment. Phil Bernstein, vice president of Industry Strategy and Relations, AEC Solutions, discusses BIM and how digital prototypes are serving to optimize sustainable results.

Currently at the beginning stages of development, BIM provides the potential for a virtual information model to be handed from Design Team to Contractor and Subcontractors and then to Owner, empowering each to add additional discipline-specific knowledge and tracking of changes to a single model workable model. How are firms changing to incorporate this new technology, in what ways, and what are the challenges they’ve faced? Moreover, given the growing market demand for green building, firms must align the culture of practice to make a process transformation. This podcast reviews practical advice for how and why to make the transition, especially for smaller firms venturing to remain competitive.
