The Contributions of Building Information Modelling to Sustainable Construction

Global concerns toward environmental issues have induced growing demand for new approaches in the construction because of its considerable impact on the environment and use of natural resources. Through using construction sustainability tools, methods and techniques, a greener design can be applied during various building phases. In this connection, it is argued that the analytical and integrated models applied by Building Information Modelling (BIM) may also facilitate this process to be performed more efficiently. BIM and construction sustainability are quite different initiatives, but both have received much attention in recent years in the architecture, engineering and construction (AEC) industry. A rigorous analysis of the interactions between them implies that a synergy exists which, if properly it is understood that can be helpful to reduce the environmental impacts of the AEC industry. A BIM-based design model can contribute to sustainability through its three main dimensions which are environmental, economic and social. In this paper, by reviewing the existing literature on BIM and construction sustainability and using a matrix to analyze construction sustainability dimensions and BIM functionalities a number of interactions have been discussed. It can be concluded that despite there are many improvements in implementation of BIM in environmental and economic aspects of sustainability, its potential impact on social dimension has not been explicitly explored hence further studies need to be undertaken in this area.

Owner-dominated building information modeling and lean construction in a megaproject

The integration of building information modeling(BIM)and lean construction(LC)provides a solution for the management of megaprojects.Previous studies have generally focused on the theoretical or empirical adoption of BIM and LC.Moreover,only a few studies have examined the approach of simultaneously using BIM and LC in megaprojects.Therefore,an intensive study on the application of BIM and LC in megaprojects,particularly to explore considerably effective integrated application modes of BIM and LC in megaprojects,will substantially promote the management efficiency of megaprojects.The current study describes a method that integrates owner-dominated BIM and LC that was developed in a case study.The proposed method provides a framework for all stakeholders to use BIM and LC in a megaproject dominated by the owner.The interactional relations among the owner,BIM,and LC were analyzed and positive interactions were identified.These positive interactions served as a basis for the implementation of this integrated approach in a case study and could be applied to other megaprojects.The megaproject(i.e.,airport construction project)was examined to verify the performance of the developed method.Results showed that the integration of BIM and LC dominated by the owner can improve management performance and achieve high quality standard.
