BIM (Building Information Modelling) is a process based solution to collaborative approach towards project coordination that is increasingly becoming indispensable for the AEC (Architecture, Engineering & Construction) industry.  Fundamentally, it is a software driven process which provides the project delivery team with a Virtual 3D visualization of the look and feel of the building that is to be constructed along with additional information from conceptual stage to O&M of the infrastructure.

Traditional building design was largely reliant upon two-dimensional technical drawings (plans, elevations, sections, etc.). BIM extends this beyond 3D, augmenting the three primary spatial dimensions (width, height and depth) along with its’ metadata as a BIM Model with time as the fourth dimension (4D), cost as the fifth (5D), Energy Simulation as the sixth (6D) and Facility Management as seventh (7D) and so on…
