Building Information Modeling (BIM) is an innovative approach to design, construction, and management and is the next generation of building design. CRG has been using BIM, and the Revit software that supports BIM, to design buildings since 2006.
As opposed to traditional drafting systems such as CAD, Revit is a modeling technology that captures and presents building information dynamically. The Revit model combines project views (drawings and schedules), annotations (dimensions, sections, details, etc.), and building components (doors, windows, beams, ducts, light fixtures, etc.) into an integrated whole, ensuring that any change in one component is instantly reflected everywhere. It is displayed as a 3D model, and is as realistic as the amount of information entered allows.
Revit is an excellent graphic tool, but its primary value is in eliminating waste and inefficiencies caused by poorly coordinated drawing sets, and the resulting hours of rework. The model, including the documentation, is always coordinated, consistent, and complete. In addition, Revit links all phases of a project, from conceptual to detailed design to construction drawings. The consistent flow of digital information minimizes the time and effort traditionally needed to connect the separate and unrelated software environments for each phase.

Revit and Green Building

Sophisticated analyses are critical to designing for reduced energy consumption. Typically this is outsourced, and the energy performance information is available only at fixed points in the project, not necessarily when it would be most useful. Revit can link to the Green Building Studio service or other engineering analysis systems automatically, significantly reducing the cost of this information and providing accurate energy use estimates for the building during any design phase.
