respect to cost for systems cost estimate by UBTSL and that by JARTS is nearly equal. (only 2% difference)
With respect to rail vehicle, cost estimation by UBTSL is a little less than by JARTS (13% difference) With respect to software, namely cost for items 22 〜 item 29, the total cost for software shares nearly 38% of total, cost for hardware (namely S6/S5 = 0.38). How much cost should be estimated for software depends on the policy / strategy of the enterprise concerned in carrying out the project.
Cost for engineering, management & administration, construction management may be decreased by making use of local Indian consultants / experts experienced in railway systems. Cost for cortigency and project reserve depends on the policy of the enterprise against the various risk the enterprise may encounter while constructing the project.
In summarizing the review UBTSL is kindly requested to reconfirm the cost estimation for civil engineering structure and track.
In India' there will be many experiences in constructing similar railway civil engineering structures and railway tracks. In this context, reconfirmation by UBTSL in these civil engineering and track areas could be easily done with cooperation of engineers from such organizations as Indian Railway Konkan Railways, Calcatta Metro, etc.
