BIM-centered high-speed railway line design for full infrastructure lifecycle
Abstract In the field of civil engineering, specifically within railway projects, the adoption of Building Information Modeling (BIM) has become imperative. However, the sector's adherence to traditional methods for infrastructure design and management has delayed the widespread adoption of BIM. This paper describes a BIM-centered methodology applied to a real-world High-Speed Railway Line (HSRL) project. Through an extensive examination of HSRL design parameters and the integration of various BIM-based tools, a 3D parametric design model is generated. This model serves as the foundation for evaluating up to five design alternatives, considering technical and economic aspects. Furthermore, a degradation model is proposed to assess alternative performance over the infrastructure's full lifecycle under specific rail traffic assumptions. This facilitates a rapid evaluation of alignment design's impact on maintenance costs. The paper draws two main conclusions with potential benefits for both private companies and railway administrations: Firstly, BIM proves feasible and advantageous despite some interoperability challenges, highlighting the need for continued advancements in BIM software compatibility. Secondly, the proposed approach can potentially lead to up to 40% cost savings in maintenance for railway administrations.

Highlights The influence of the horizontal alignment design of a High-Speed Railway Line (HSRL) on its maintenance period is analyzed. A BIM-centered method has been proposed to evaluate both construction and tamping costs. The importance of considering the maintenance costs during the design phase has been demonstrated. The interoperation between an alignment design tool and a budget management software has been tested. The method is applied to a real HSRL project in Spain.
