SOURCES OF FUNDING PHASE-2(CONTD)

Funding agencies being tied up are JICA, ADB, AFD, World Bank, HUDCO,

Domestic Banks and Financial Institutions.

While approving Phase.2 of Metro project, the GoK has approved the

following measures for additional resource mobilisation through land

monetization :

a) Development cess: Levy of development cess on new layouts by BDA

and private layouts . This levy is estimated to yield revenue of Rs. 1250

Crores in five years.

b) Cess on additional floor area ratio(FAR): Allowing additional FAR along

the Metro Rail Corridor. This is estimated to yield Rs.430 crores in five years.

c) TDR in lieu of compensation of land: cost of land.

d) Issue of taxable bonds. Depending on the market appetite BMRCl may

float Bonds to pay off costlier loans.

Challenges in Tunnel Construction(contd) Underground alignment is only in One corridor(line 6)- Gottigere-Nagawara line. Approximate length 13.790 kms No. of stations 12 (one station-MG Road U/G – is an interchange station with the elevated MG Road station of Reach 1 of Phase.1) • There will be traffic interchanges at - Shivajinagar U/G station with Intra-City Bus terminal - Bangalore Cantonment U/G station with the National Railways station contd..

Challenges in Tunnel Construction ( contd)

Geo Strata is ‘ Mixed soil ‘ - Sandy silt

Weathered Rock

Soft Rock

Hard rock (comp strength 50 to 30mpa)

Water table is hardly 3 m below ground at places

Extensive ground stabilization measures are involved by Soil nailing, Rock anchoring, Grouting, etc.

Temporary support arrangements are massive- Solder piles, Secant piles, etc.

Rock excavation - Controlled Blasting with instrumentation.

- Sawing of rock by chain saws

Water proofing at Stations

- Anti Base slab flotation measures

- Road diversions and Decking of roads.

Cut and Cover Station excavations- On site Visualization program

Tendering for U/G Works- Phase -2

Geo Tech exploratory bores work has just started and will be completed by Aug.2013. It will be a combination of ‘Design and Construct’ and ‘Construct only’ package.s 1 USD=INR 50.00 There will be 3 packages 3.34 kms twin tunneling, 4 .stations Cost INR 14030m USD 280.60m 3.19kms twin tunneling , 4 stations Cost INR 13450 m USD 269.00m 4.01 km twin tunneling ,4 stations Cost INR 15140 m USD 302.80m Tunneling will be ‘Design and construct’ U/G stations may be ‘Construct only’ or ‘Design and construct’ Three envelope system - Qualification - Technical proposal - Financial proposal ‘D & C’ will be a lump sum quote ‘C only’ will be based on Bill of Quantities(BoQ) on which contractor quotes a premium percentage. There will be Price Variation Clause(incl.Lumpsum portion) Tender Notification likely to be issued in January- March 2014.
