An Analysis of the Cost Associated with Diversions Caused by Metro Rail Construction Work

Metro rail development has gained considerable traction in several Indian cities. The success of Indian infrastructure development will have a major impact on the success of a metro project that requires substantial capital expenditures. A large number of metro projects have already been completed, some are currently in progress, and many more are expected to be completed in the near future. The benefits offered by these projects are estimated in the Detailed Project Report (DPR) which also mentions different costs such as construction cost, rolling stock, signaling systems, etc. The road user cost due to diversions is seldom included in the total cost which is a major indirect contributor. This chapter is based on the data collection of the Pune Metro Rail construction in corridor II between Vanaz to Deccan, specifically related to route diversions. In this research paper, authors studied and analyzed the cost of diversion faced by the commuters during the construction of Metro Station at Nal stop on the busiest route. Traffic study using the moving traffic count survey were conducted at different locations as per guidelines given in IRC-106. The diversion cost is determined using the methods described in IRC SP 30. The cost of diversion is calculated using both distance and time related Vehicle Operating Cost (VOC) for the period of 2016–2022. The authors estimate that this cost is more than 6% of the cost of construction.
