BIM is a great innovation in building industry

BIM is defined as highly flexible object-oriented design process that provides viable platforms for multi-disciplinary integration

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

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

BIM has been used successfully for quantity take-off estimates

It has been reported (CIFE 2007) that using BIM leads to Cost estimation accuracy within 3% and up to 80% reduction in time taken to generate a cost estimate
