TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 1100 CCOOSSTT EESSTTIIMMAATTEE 10.1 INTRODUCTION The capital expenditure for the project has been assessed for the corridor (Panvel – Kopar – Vasai Road – Virar) including proposed Depot for a total length 70.14 Km from proposed buffer end at Panvel to Virar Railway station. The proposed corridor consists of 16.277 Km elevated (including 3.35 Km ramp portion) and 53.863 Km (including major bridges on rivers, highways and Railway crossings) At-grade section. A total of 24 stations are proposed (5 Elevated and 19 at-grade). 10.2 CAPITAL COST ESTIMATES The cost estimates have been prepared covering Civil, Electrical, Signalling and Tele Communication works, Rolling stock, Environmental protection, Rehabilitation works, etc. The cost estimates are worked out at Jan’13 price level. The proposed elevated Fast Corridor alignment has been found feasible as a combination of elevated and At-grade, in different sections: At grade: from Panvel to North of Nilaje Railway Station (20.84 Km length) Elevated: from Nilaje to Koper including bridges over Panvel-Diva line (between Nilje-Dantivali section), connecting loop and Diva-Kalyan Main line. At-grade from Kopar to Juchandra Railway station (32.698 Km length including major bridges on Kaman river, Ulhas river and RUB/ROB over highways). Elevated from Vasai Road station and continued parallel to Western railway tracks up to Virar Railway station. (9.75Km). An area of approx 33 hect. for car depot is proposed at Kalwar. While preparing the capital cost estimates, various items have been grouped under three major heads on the basis of (i) route km length of alignment, (ii) number of units of that item and (iii) item being an independent entity. All items related with alignment, whether elevated or at-grade construction, Permanent way, OHE, Signalling and telecommunication, whether in main lines or in maintenance depot, have been estimated at rate per route km basis. Few items like Rolling stock have been estimated in terms of number of units required. The rates of various items have been adopted on the basis of reports for Elevated Corridor from Churchgate – Virar , CSTM-Panvel and Virar –Dahanu Road submitted by M/s RITES and comparable rates of other projects. The capital cost worked out for proposed Corridor is presented in Table 10.1 (for PNVL- Virar corridor) . The overall capital cost amounts to Rs. 6506.61 Crore at Mar’13 price level including design charges @ 2%, general consultancy charges @ 6% on all items and 5% contingencies on all items. These costs cover all taxes, like excise duty, custom duty, VAT, etc. Final TES & Detail Project Report Sept, 2014 10-1 TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 10.3 CIVIL ENGINEERING WORKS 10.3.1 Land (i) Total Land requirement has been worked out to be 64.36 ha. including for the depot: Govt. land = 7.59 ha Private land = 23.6 ha. Depot land = 33.15 ha. (ii) Cost of private land has been worked out area wise based on prevailing rates for commercial / residential properties as per Ready Reckoner published by Architects Publishing Corp. of India Mumbai (2011 edition) suitably increasing the same for proposed enhanced compensation based on land acquisition act. For depot land, where major area is involved, rates adopted are based on land rates given in revenue department booklet, duly increased on similar lines. However this still will be an approximate assessment as actual compensation may vary based on negotiations and sale deeds in the area. (iii) For Govt. / Municipal land, rates adopted are based on feasibility / DPR reports of Elevated corridor from Churchgate to Virar project, as well as rates given in revenue department booklet. 10.3.2 Formation and Alignment (i) Elevated section (a) In Virar to Vasai Road section, proposed Corridor will be elevated. The rates adopted are based on Elevated corridor from Churchgate to Virar project rates. (b) Extra provision has been made for crossing over the existing railway tracks from east to west or vice versa, required due to site conditions. (c) Separate provision for ramps has been made, as the elevated corridor has to be taken to ground level and from ground level to elevated at a number of locations due to availability of land and other site conditions. (ii) At grade section Cost of at-grade section has been assessed considering height of embankment, blanketing, provision of boundary wall with fencing etc., utilities like minor bridges, protection work required, etc. Final TES & Detail Project Report Sept, 2014 10-2 TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 10.3.3 Station Buildings (i) Elevated stations (a) Civil works include special design stations with 270 m length. Cost also covers the viaduct length in station. (b) Separate provision for E & M works has been made for elevated stations, based on Elevated corridor from Churchgate to Virar project and duly updated. (ii) At grade stations Civil works costs for at-grade stations has been assessed excluding alignment length, lifts and escalators, Permanent way, E & M works. Cost of E & M work excludes O.H.E. but covers escalators, lifts and other E & M items. 10.3.4 Permanent Way For elevated sections, as well as for at-grade section, ballasted track has been proposed. For ballasted track, the rates adopted are based on IR rates. 10.3.5 Depot at Kalwar Cost of depot is worked out based on facilities required to be provided initially .Cost of land has also been included in cost estimates. 10.3.6 Traction and Power Supply Provisions have been made to cover the following subheads: OHE (Flexible/ OHE Rigid). Receiving – cum Traction Sub – stations including cables, etc. ASS for elevated at-grade / underground stations Service connection charges for Receiving Sub-station SCADA Centenary’s maintenance vehicle Miscellaneous items e.g. illumination, lifting TandP, etc. Rates adopted for various items are based on costs of work being done for Delhi Metro. 10.3.7 Electrical Services at Stations These are included in estimated costs of stations for underground / elevated / at grade alignment section separately. Costs of escalators, lifts for elevated / at grade stations have not been included in station E & M costs Final TES & Detail Project Report Sept, 2014 10-3 TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 10.3.8 Signaling and Telecommunication Works Rates adopted are based on rates of comparable sections of other DPRs of Railway Projects undertaken by RITES. These rates include Design, manufacture and supply of equipment and their installation at site. 10.3.9 Rolling Stock The rolling stock cost is based on rates for supply of comparable AC coaches. 10.3.10 Utility Diversions Main Sewers / Water pipe lines are generally running across the existing Corridors. These are therefore, generally not affected and do not need diversion. Column locations of the elevated Corridor may need to be adjusted at the time of construction. For at-grade section, Sewer and Water lines will not be affected; only drains running parallel may need diversion, provision for which has been made. Along the existing Corridors, electrical / signal cables may need diversion / provision of new cables. To avoid interruption to the existing system, new cables will have to be laid. Provision for the same has been made. Other important utility works required include road diversion / traffic diversions. As regards other utilities like over head electrical crossings, relocation of electrical S.Ps, old T.S.S., etc. specific provision has been assessed for each item and shown in the estimate. Provision for all other utility works has been made on route km basis. 10.3.11 Environmental Impact Provision for environmental impacts of this Corridor has been made to cover various protection works, additional compensatory measures, compensation for loss of trees, compensatory deforestation and fencing, monitoring of water quality, air / noise pollution during construction, establishment of Environmental Division, etc. Rehabilitation and Resettlement Private structures – Provision towards compensation/rehabilitation of these structures likely to be affected has been assessed after site inspection. Adequate provision has been made to cover cost of hutments and other structures. Provision for cost of relocation of hutments on Govt. land has also been made. Provision for relocation cost of railway structures has also been made and shown separately. Final TES & Detail Project Report Sept, 2014 10-4 TECHNO-ECONOMIC SURVEY AND PREPARATION OF DPR FOR PANVEL-DIVA-VASAI-VIRAR CORRIDOR 10.3.12 Inter Modal Integration and Dispersal Facilities The Transport Integration measures are proposed to facilitate efficient transfer/ dispersal of passengers from/ to the proposed system and effective inter-modal interchange of the passengers with the feeder modes including walk. These measures also aim to provide the proposed system’s integration with the entry/ exits of existing suburban system and upcoming transport infrastructure. The suggested measures aim to augment the present transport infrastructure and dispersal facilities to handle the additional traffic volumes. These include traffic management, removal of soft encroachments, up-gradation/ widening of walkways, pedestrian cross-over facilities, new/ augmented bus/ IPT stands, planned pick-up/ drop-off areas and parking facilities. The exercise for planning of the inter-modal integration and dispersal facilities has been carried out for all the proposed 24 stations. These are in addition to the station dispersal facilities described as part of the architectural report. Block cost estimates of these proposed measures have been worked out based on similar recent works in Mumbai. 10.3.13 Road Traffic Diversion The proposed measures include the construction of traffic diversion roads/ footpaths, temporary shifting of IPT/ Bus stands and associated barricading.
