BIM D's  (dimensions) ?  – 2D, 3D, 4D, 5D, 6D, 7D, 8D. 2D BIM  – 2D drawings (with x & y axis) & documentation, views, plans, etc. 3D BIM  – shared information model used for visualization purposes, coordination, etc. 4D BIM -  (4D = 3D + TIME SCHEDULE) adds an extra dimension of information to a project information model in the form of scheduling data. 5D BIM -  (5D = 3D + TIME SCHEDULE + COST) assemblies with time schedule constraints and then with cost-related information. 6D BIM -  (6D = 3D + TIME SCHEDULE + COST + MAINTENANCE) assemblies with all aspects of project life-cycle management information. 7D BIM -  (7D = 3D + TIME SCHEDULE + COST + MAINTENANCE + SUSTAINABILITY) optimizes asset management from design to demolition. 8D BIM  - (8D = 3D + TIME SCHEDULE + COST + MAINTENANCE + SUSTAINABILITY + PREVENTION) for accident prevention through Design.
