An Overview of Building Information Modeling (BIM) & Construction of 4D BIM Model

The volume of construction output will grow by 85% to $15.5 trillion worldwide by 2030, with three countries – China, US and India – leading the way and accounting for 57% of all global growth. Construction industry largest industry worldwide comprising Architecture, Engineering and Construction professionals, Mechanical, Electrical, Plumber professionals, etc. The AEC industries have long sought techniques to decrease project cost, increase productivity and quality, and reduce project delivery time and one of the trending techniques is BIM (Building Information Modeling). BIM is intelligent model-based concept, in which buildings are built virtually before they get constructed actually on the grounds, where all the information in integrated in common platform as a result we get virtual data rich model of the structure. BIM plays crucial role in decisions making during its lifecycle. This paper describes the software’s and methodology used for construction of 4D model. The BIM and normal construction process, dimensions of BIM are also explained in this paper. 4D model can be used by project managers for effectively manging tasks and resources.
