Management and engineering solutions for railway station development

Abstract

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.
