In terms of climate change and the scarcity of resources, it is necessary for the building sector to sufficiently evaluate the decision-making for new construction projects. In addition to building construction, this is also of utmost importance for infrastructure projects. The greatest potential to reduce the environmental impact of infrastructure projects occurs in early design stages. However, information to assess environmental impacts is difficult to obtain and time consuming to collect at that early design stage. In this context, a methodology is presented for infrastructure projects, which intends to support the decision-making process of different road routing alternatives. In particular, this involves a LCA based on BIM. Therefore, the BIM models are linked with predefined LCA profiles. The bill of quantities is automatically derived from the BIM model for reducing the manual workload and to automate the subsequent integration and calculation process of the life cycle assessment. With the help of a prototypical implementation and a subsequent case study, the embodied and traffic-related emissions are determined. For a holistic decision-making process, the resulting global warming potential of the different variants is compared, and the individual factors are evaluated in relation to each other.     «
