BIMBIM Unlike conventional CAD tools, BIM uses
intelligent objects to represent distinctive features in designs
The AIA defined BIM as a model-based technology linked with a database of project information and this reflects the general reliance on database technology as the foundation for BIM

BIMBIM BIM uses objects such as: walls, floors,
roofs, windows, doors, etc
The objects are tied to a database that contains all data related to the geometry, spatial relationships, geographic information, quantities, and properties of the building components

BIMBIM As such, the drawing becomes a model that
is information rich and can readily be used to visualize the entire building lifecycle including the processes of construction and facility operation / maintenance

BIM: BIM: BIM is not simply a drafting tool, like 2D
computer drafting. It is, more precisely, a design tool
Each object in the model contains many levels of data about that object; a window contains information on its dimensions, glass selection, color, hardware, cost, and even its required schedule for delivery

i-room (or Big room)
The Big Room is large enough to house the entire team and allows every one to follow the process in detail
Get the team together in one spot: Architects, Structural, Mechanical, etc.

BIM: BIM: Ability to create an accurate and intelligent
model which is useful throughout the entire life of a facility
Parametric modeling; objects are related parametrically therefore a number of related conditions can be updated by changing only one property

Potential increase in using BIM
Lacking of skilled BIM candidates
Accordingly, BIM should be taught as subject for construction and civil engineering students
Or, reconfiguring the current courses to integrate BIM into their contents
