“…The feasibility of using 3D printing and structures for high-speed railways in urban development satisfies not only the regulatory conditions, but is also based on ensuring the economic efficiency of such innovative projects, including the main trends: "green technologies", information modeling technologies (BIM), digital construction, printing with clay, geoconcrete, self-repairing concrete [3][4][5][6][7][8][9][10][11][12][13].…”

The current trend toward the use of 3D concrete printing represents a vector for green financing of innovative transportation projects and a shift from traditional construction to additive manufacturing and a closed-loop economy. The potential impact of additive technology in the field of transport infrastructure is expected to be greater than in any other, due to the scale of construction printing and its environmental potential to ensure the environmental safety of transport construction at the global, regional and local levels, which appears to be a relevant interdisciplinary research area. The article analyzes the transition to a "green economy," including the introduction of additive technologies and the rational use of construction resources. The article gives proposals for energy-efficient and ecological green construction of high-speed railways and provides a rationale for the use of additive technologies using 3D-printed noise protection walls made of eco-concrete (green concrete, geo-concrete). The main recommendations on the choice of structures, optimal for the implementation of active noise protection measures on high-speed railways and artificial constructions are given. Presented the work of PSTU students of the Faculty of Transport Construction on the subject of 3D printing of noise protection panels with different acoustic performance. Modern architectural solutions were made with the preparation of a feasibility study on the implementation of innovations and the development of green design competencies.

This paper presents a methodology for construction engineering management of railway station redevelopment. The station working capacity is taken into account and the stages of preliminary and main works are determined. The scope of work to be performed by a building contractor is substantiated to provide an optimal station performance. The volume and scopes of work for specific and complex construction workflows are grouped by the components of the railway marshalling yard.The optimal volume of work of the complex flow F has been determined (as a percentage of the total estimated cost of the facility). The station working capacity Nв has been taken into consideration in correlation with the given conditions of construction or renovation works.The key construction flow management options have been worked out based on the optimal index of construction work sequence, prime cost reduction of construction and installation works (current costs C), and effective capital investments into machines and mechanisms (one-time costs Кf).The proposed methodology for construction management and engineering solutions is oriented to general contracting and subcontracting companies of the railway construction sector. This methodology is intended to lower the prime cost of construction and installation works and to reduce the time of construction and redevelopment of railway stations.

“…Disruptions in the transportation process due to the realization of risks at the main infrastructure facilities of JSC "Russian Railways" predetermine the economic consequences both for consumers of services, operators, and infrastructure owners. Several studies in terms of justification of innovations, and project management in the field of safety and efficiency of railway traffic [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] do not fully take into account the specifics of the unique object under study. The existing methodologies need to be refined and continue to be tested.…”

Study of the issues of identification, analysis, and comparative assessment of the risks of violations of the safety of the main railway transport infrastructure. The aim of the study: is to develop a methodology for the identification of economic risks of investment projects of construction of mainline infrastructure of railway transport. The object of the study: railway transport enterprises involved in all stages of the life cycle of the mainline infrastructure of railroad transport. The subject of the study: tools and procedures for the identification of economic risks of violations of the security of trunk railway transport infrastructure. In the turbulent global economy, the effectiveness of project management is based on the perception of the human factor as the main in the formation of aggregate uncertainty. Large infrastructure companies should pay special attention to the identification, analysis, and assessment of project risks. One of the key figures in Russia's transport communication, influencing not only domestic traffic flows, but also international logistics chains, is JSC "Russian Railways". Disruptions of the transportation process due to the realization of risks at the main infrastructure facilities of JSC "Russian Railways" predetermine economic consequences both for consumers of services, operators, and infrastructure owners.
