Abstract

The objective of this paper is to evaluate the proposed design by the Value Engineering (VE) analysis for the gravel ballast and the concrete ballast track structures. However, reliabilities about the VE analysis results based on Life-Cycle Cost(LCC) has not been fully benefited from VE implementation due to disregard of basic principles and lack of systematic performance measurement systems. In this paper, the VE analysis using the Delphi survey of professional group is proposed to decide reasonable determinants for investment and alternative design in construction project of railway tracks. Moreover, the efficiency of VE analysis is invested by an application of the developed methodology to track structures.
