Railway Project Work Implementation with Critical P ath Method and Value Engineering

Abstract

Analysis on the maintenance of the railway track was performed in this study. The maintenance was conducted to replace the R.41/R42 bearing iron with the R.54 bearing concrete on the railway track. The railway track maintenance project was run based on the unit price contract as decided by the state – owned Infrastructure Maintenance Operation for Railway. The unit price contract was selected to utilize existing resources as much as possible. The problem of this study was to investigate the influence of the Critical Path Method and Value Engineering with analysis on of the railway tract project. The main objective of this study was to investigate the time and cost efficiency time and analyze the influence of the Critical Path Method and Value Engineering (VE) on this case study. The analysis resulted in the influencing factors such as activities stage process (RII =0.58021), project planning (RII=0.57176), Implementation (RII=0.58194), Support (RII=0.57250), Structural Planning (RII=0.64653) Supervision (RII=0.55556) External Conditions (RII=0.57222) and Railway Work (RII=0.59144). The Case study using critical path method with the variable score CPM(X1) to the railway track (Y) resulted in the significance limit value α = 1.995 more than the significance level of 0.824. The analysis showed that the variable CPM(X1) had significant influence on railway work (Y), while variable Value Engineering (X2) resulted in significance α = 1.995 more than the significance level of 0.001. Therefore, the variable VE(X2) influenced on railway work (Y).
