Definition:

Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle using three-dimensional, real-time, dynamic building modeling software to decrease wasted time and resources in building design and construction.  This process produces the building information model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components.

BIM offers:

• Improved visualization
• Improved productivity
• Easy retrieval of information
• Increased coordination of construction documents
• Improved visualization
• Reduced costs
• Increased speed of delivery
• Embedding and linking of vital information such as vendors for specific materials, location of details and quantities required for estimation and tendering.

Parametric Change Engine

A fundamental characteristic of a building information modelling application is the ability to coordinate changes and maintain consistency at all times. The user does not have to intervene to update drawings or links.

The Parametric Change Engine uses the information captured as the designer works to build a network of relationships between elements. When the designer changes something, the software immediately applies that change to any affected elements.
