Abstract: Building Information Modelling (BIM) is a process involving generation and management of digital representations of physical and functional characteristics of a building or a facility. It is a holistic documentation process for operational visualization, design coordination, estimation and project scheduling. BIM software defines objects parametrically and it is a tool for virtual reality. Primary advantage of implementing BIM is the visual coordination of the building structure and systems such as Mechanical, Electrical and Plumbing (MEP) and it also identifies the possible conflicts between the building systems. This paper is an attempt to develop a model which would highlight the primary advantages of application of BIM pertaining to real estate development projects. It has been observed that about 40% of the Architecture, Engineering and Construction (AEC) companies use BIM but primarily for their outsourced projects. Also, 65% of the respondents agree that BIM would be used quiet strongly for future construction projects in India. Further, about 40% of the users would like to use BIM for project co-ordination, about 20% for conceptual design and about 15% for detailed design. The 3D models developed with Revit 2015 software would reduce co-ordination problems amongst the architects, structural engineers, contractors and building service providers (MEP). Also by means of virtual reality, the client would be having a feel of the building model before actually the building is constructed. The chances of the collisions of the different utilities and services are also minimized.
