Abstract
The study includes a review on the building information modelling process in terms of its necessity, application, structure and future scope. BIM with its integrated drawings make the complex projects easy to interpret in terms of various complex layouts incorporated together. The study shows major advantage of using BIM in terms of design customization and possibility of change at any stage of project. Changes made in the BIM drawings automatically reflected in the whole project. Building Information Modelling (BIM) has been an important topic of discussion for a long time, but as compared to its starting rise with the initial time frame, its growth have shown a decline. Now a days BIM has been used by mostly Architects and only a handful approximately 10% engineers use it. The reason for wide adaptation is the clarity of terms and flexibility of use. Apart from that there are some fields in which very less work has been done like cost estimates, quantities can be automatically calculated but integration of these with cost is a major objective for developers to achieve. Not much clarity regarding the use of BIM in pre-existing buildings is present. In this research, an attempt has been made to make the term clear firstly difference from CAD, the basic structure is clearly explained and some less explored fields are discussed. Among these fields are cost estimation from quantities and use of BIM for pre-existing building. In ending a small survey results have been represented to show the adaptation status of BIM in Facility Management.
