Typical BIM Benefits
•Better understanding of design

•More focus on value-added tasks •Faster cycle times
•Reduced errors and omissions
•Less waste: rework, materials, time Fewer translation errors and losses Lifecycle Knowledge Readily Exchanged

BIM

Existing information already in the BIM is used as input and information that is
gleaned from the exchange is also stored in the model (i.e. Attributes about the doors purchased, size, material, cost, instructions, fire rating, etc.) NCS, IFC’s, OmniClass
More information is added to the building information model in its appropriate spatially related location
Use of Information Exchanges to Support BIM
•Requirement & Goal
–Standardize on information needed for specific tasks within the building lifecycle within the building lifecycle –Development based upon open data standards used by all
–Provides requirements to software companies
•North America data standards
