Introductions
Many firms have combined computa5onal design and building informa5on modeling and are delivering real work using new tools and prac5ces. In this session we will learn how two industry-‐leading firms have gone from experimen5ng with computa5onal design to using it in prac5ce on real projects. Both firms are itera5ng on more design ideas, increasing the quality of work and delivering more quickly by successfully using advanced soCware tools. We will hear about case studies from NBBJ and RTKL and then hold a Q&A to discuss both commonali5es and differences in approach.
What is this BIM thing?
• What exactly is BIM? • Virtual Building • Embedded Intelligence
• Simula;on and Analysis • Underlying Parametric and Associa;ve Model

How are BIM and parametric tools related? A Parametric and Associa;ve Model
While Revit undoubtedly uses parametrics for these automa5c revisions, unlike fully fledged parametric modelling soCware such as Pro/ENGINEER, CATIA, or even Sketchpad, the parametric rela5onships of Revit are hidden behind the interface. The focus is on using parametric models rather than crea4ng them.
Therefore, while the majority of architecture firms may never use overtly parametric soCware like Digital Project or Pro/ENGINEER, most – oCen without even considering it – use parametric equa5ons in some capacity to model their buildings.
