REVIEWING THE SCOPE OF BUILDING INFORMATION MODELING (BIM) FOR INDIAN SCENARIO

Abstract

BIM is an intelligent parametric, object-based design methodology that is compelling the design community to transition away from unintelligent nonparametric, computer-aided drafting (CAD) processes. The design communication is gradually being changed from 2D based to integrated 3D digital interface. Building Information Modeling (BIM) is a model-based design concept, in which buildings will be built virtually before they get built in the field, where data models organized for complete integration of all relevant factors in the building lifecycle which also manages the information exchange between the Architecture, Engineering, and construction professionals, to strengthen the interaction between the design team. BIM is a shared knowledge about the information for decision making during its lifecycle. There's still much to be learned about the opportunities and implications of this tool. The impact of BIM on the evolution of design tools in the AEC industry has recently become a topical research area. It is found that BIM adoption is much higher in the US and Finland than in the rest of the world. In India the use of BIM is quite low for AEC's till date and conventional entity based CAD software remains the drafting tools. The core barriers include a lack of training and technical support, a lack of requirements from client, and the unavailability of free trial software. This report deals with the status check of BIM application in India. To do that a Survey has been designed to check the acceptance of BIM till date, and another methodology Hands on Experience, (HoE) has been adopted. The HoE identifies areas which provide added advantages and value through the use of BIM at the Schematic Design stage for communication of information and the manner the information is obtained. This application is widely accepted throughout the AEC industry in many countries for managing project information with capabilities for cost control and smoother facilities management..
