The cost converted from the cost estimated in Japan is larger than the cost estimated by UBTSL The comments on this difference will be presented as follows:
(a) The unit cost of track material was not obtained in Bangalore, accordingly these unit costs were collected in Japan and converted to Indian costs based on conversion ratio as shown in Table 9,3.3-2. It is suggested that UBTSL should confirm the unit cost of each track material available in India.
(b) Exact quantity of track work special such as split turnout, diamond crossing were not clearly indicated by UBTSL. Accordingly, they were suitably counted by JARTS. It is recommended that UBTSL should confirm the quantity of each type of trackwork special.
(c) Generally the percentage of track cost against total cost (excluding rolling stock cost land cost and engineering / contingency) in Japan is 9〜4% as shown in Table 9.3.3-8. In case of Bangalore ELRT case, track cost (including contact rai1 cost) percentage is 2.7% in case of UBTSL,s estimation, rather small percentage. If we exclude contact rail cost from Track cost track cost percentage will be further small.
Considering these (a), (b), (c) above, it is suggested that UBTSL should reconfirm the track cost.
