Further we assumed that all major machines will be imported, namely the unit cost of machine depreciation in Bangalore will be 1.2 times that in Japan. These will make the construction cost in Bangalore nearly equal to that in Japan. Therefore the cost estimated by JARTS is nearly equal to the cost necessary for structures executed in Japan.
(b) The cost for installing escalator and elevator was newly calculated and added to JARTS cost estimation.
(c) The length of cost-in-place pile of every foundation was assumed as 20 m.
It is suggested that UBTSL should confirm the cost for civil engineering structures, Indian civil engineers have experiences in many similar civil engineering projects. Accordingly it will be easy for UBTSL to confirm the cost for civil engineering structures.
9.3.3 Track
(1) Track work including Contact Rail
(a) Track work
Estimation of track work in Japan is given in Table 9.3.3-1. Cost of rail, sleeper and fastening are based on the purchasing cost by JR group or JRCC (Japan Railway Construction Public Corporation).
Ballast Volume per double track route meter is calculated as follows according to Fig. 6.3-1
V1 = (0.2 + t) m x (2.6 + 0.200 + 0.450) m x 1 m x 2
= (0.2 + 0.235) x (3.25) x 2 =2.828 m3
V2 = (t x w x 2.6) x 2
= (0.235 x 0.25 x 2.6) x 2 = 0.306 m3
S = Sleeper spacing (0.714 m) 1400 piece/km
t = thickness of sleeper (0.235 m) (*)
w = width of sleeper (0.25 m) (*)
V = V1 -V2/S
= 2.828 - 0.306 / 0.714 = 2.828 - 0.428
= 2.40 m3/m
(*) Based on Indian Railways' prestressed concrete sleepers
Cost of ballast per track meter can be calculated by V/2 x unit cost/m3 (Unit cost is based on JRCC or JR's purchasing cost)
