What is Building Information Modeling
Building information modeling (BIM) is the process of generating and managing digital representations of both physical and functional characteristics of buildings or assets. Typically BIM files are shared and exchanged to support strategic decision-making.
BIM representations are a combination of objects, generic or product-specific, they include solid shapes or void-space oriented shapes (like the shape of a room). These objects convey a specific geometry, relations and attributes.
BIM design tools allow extraction of different views from a building model for drawing production and other uses. These different views are automatically consistent, being based on a single definition of each object instance. BIM software also defines objects parametrically; that is, the objects are defined as parameters and relations to other objects, so that if a related object is amended, dependent ones will automatically also change. Each model element can carry attributes for selecting and ordering them automatically, providing cost estimates as well as material tracking and ordering.
Building Information Modeling tools improve and streamline operations and maintenance. The benefits include:
■ Reduces rework
■ Improves productivity
■ Reduces construction changes and conflict
■ Reduces building plan challenges and conflict
■ Fosters collaboration
■ Improves predictability
■ Seamlessly integrates with mobile
