Sustainability through the use of Building Information Modelling in infrastructure planning

Abstract

This study examines the role of Building Information Modelling (BIM) in infrastructure planning from a sustainability perspective. It emphasises how BIM can contribute to the promotion of ecological, economic and social sustainability. Interviews with experts have shown that BIM can not only optimise the energy consumption of infrastructure projects, but also lead to precise material quantification and optimisation. Despite the benefits, the use of BIM in infrastructure planning is limited, especially in small and medium-sized projects and with local authorities. The study identifies challenges such as the complexity of BIM software systems and the additional costs of implementing them. Recommendations for action include training clients and engineering firms in the use of BIM for cost forecasting and extending the digital twin concept beyond the construction and planning process. The results show that widespread BIM application is only possible if both clients and planning offices share sustainability goals and are prepared to bear the additional costs for BIM planning. The work emphasises the need to use BIM beyond building construction for sustainable infrastructure development and provides insights into the practice of engineering firms in the infrastructure sector.
