Efficiency of Planning the Reconstruction of Railway Facilities Using BIM

The development of industrial enterprises and the growth of the logistics market require a new approach of planning the construction and reconstruction of railway infrastructure facilities. For the efficient functioning of the transport system, it is necessary to balance the infrastructure capacity and the needs of the freight and passenger transport market. Uneven growth in traffic volumes applies an extra load to the railway network.Reconstruction of an infrastructure facility can be considered as a phased increase in the production capacity of an enterprise, considering the indicators of net present value (NPV) and labour costs based on the dynamic programming method.The article analyses the issue of using BIM‑modelling in planning the reconstruction of railway infrastructure facilities. The concept of a digital railway is considered as an example since digital railway projects are the main drivers of the economy of many countries.Reconstruction of railways in the context of a lack of information about the existing infrastructure facility is an urgent problem for the design organization when conducting surveys in difficult conditions, agreeing on the list of engineering networks and linking the infrastructure of the design object with external asset holders.The objective of the article is to consider the dominant role of BIM for the infrastructure reconstruction projects using a method for economic assessment of investment options based on dynamic programming according to NPV indicator.
