Building Information Modeling (BIM) is continuously emerging as the most feasible and reliable option available in the building construction industry. With the advent of BIM — building design, construction and management has become an easier and cost effective task than ever before.

A BIM (Building Information Modeling) is the creation of parametric, or intelligent, 3D models instead of 2D perspective ‘un-intelligent’ drawings. A BIM operates on a digital database and any change made to this database is reflected throughout the entire drawing.

BIM provides the potential for a virtual information model to be handed from Design Team (architects, surveyors, consulting engineers, and others) to Contractor and Subcontractors and then to the Owner, each adding their own additional discipline-specific knowledge and tracking of changes to the single model. The result greatly reduces the information loss that occurs when a new team takes "ownership" of the project as well as in delivering extensive information to owners of complex structures far beyond that which they are currently accustomed to having.

Nowadays, many companies are using BIM for 4D visualization. BIM 4D allows for more informed decision making and better coordination between designers and builders.
