Mumbai Metro Line 3—Some questions need to be asked
Since 2004 when the Mumbai Metro Master Plan was unveiled, three of the nine lines should have been completed and should have been in operation. Ironically even the Line 1 is not complete. What is in store for the citizens of Mumbai?
Before setting out to deal with Line 3 of Mumbai Metro, a brief on the Mumbai Metro Master Plan (MMMP) is in order.
In February 2004, the Mumbai Metropolitan Development Authority (MMRDA) unveiled the MMMP at a "public presentation" without adequate and advance public announcements; it was announced by a very small advertisement on the morning of the presentation while the presentation was scheduled at 9am! MMRDA got the planning done through Delhi Metro Rail Corporation (DMRC) as their consultants. DMRC had just completed their first phase of 68.4 km of Delhi Metro for Rs10,575 crore. The elevated section for Delhi Metro had cost Rs100 crore per km and the underground had cost Rs475 crore/km and on grade, Rs20 crore/km.
MMMP in its unveiled version was a set of nine lines making a length of 146.5 km out which 32.5 km were planned underground with no on grade section. It has been planned for implementation in three phases. Phase I comprised of three lines. Line 1 is the currently under construction, 11.4 km long fully elevated. Line 2 was from Colaba to Charkop via Mahim and was underground from Colaba to Mahalaxmi. Line 3 was elevated from Mahim to Mankhurd. These were subsequently changed to make the underground section go up to Bandra to make it 40.5 km long. The then Line 3 commenced from Bandra instead of Mahim going up to Mankhurd.
The cost of the 146.5 km of MMMP at the 2004 presentation by DMRC/MMRDA was Rs19,525 crore. However, applying the costs per kilometre for the elevated and underground sections incurred in the then just completed Delhi Metro's first phase of 68.4 km to MMMP, the cost estimate for MMMP came to Rs26,838 crore. The MMMP was an underestimation primarily because the underground section was considered to cost Rs250crore/km instead of Delhi Metro's Rs475 crore/km. Perhaps being less than Rs20,000 crore would have got Cabinet approval easily may have been the strategy.
Mumbai's underground section would have to be in hard basalt rock at the depth of 20 to 25 m as against Delhi's 15 m in hard soil or soft rock. Additional costs due to this do not get reflected in Delhi Metro's underground section cost rate, a point to note.
In end 2005 Line 1 fully elevated Versova-Andheri-Ghatkopar line was put to tender as a public-private partnership (PPP) project and awarded in 2006 at Rs2,356 crore with a Viability Gap Funding (VGF) of Rs650 crore, giving a rate of Rs205 crore/km. This cost far surpassed the estimate of Rs100 crore/km applied to the MMMP in 2004.
Taking the DMRC cost as the basis for MMMP along with the Line 1 award rate and on pro-rata basis extrapolated cost of the underground section the cost rate came to staggering Rs974 crore/km as compared to the Delhi Metro's Rs475 crore/km. This has been clearly mentioned in the article published in the Economic & Political Weekly issue dated 18 November 2006.
After finding out that the cost of the underground section was very high, MMRDA changed the Line 2 as from Charkop to Mankhurd via Bandra making it fully elevated and Line 3 from Colaba to Bandra fully underground. This enabled MMRDA to proceed with the tendering process for Line 2 on PPP model of Line 1.
Despite the fact that MMRDA were aware, at least through the stated EPW article sent to them, of the costs being much higher, more than Rs60,000 crore, than the costs assumed at the unveiling of the Master Plan, they continued sticking to the Rs19,525 crore cost figure. They revised this only when they had to reveal the estimated costs of Line 2 and Line 3, which along with that of Line 1, came to be more than the Rs19,525 crore meant for all the 9 Lines put together. They attributed this to escalation and not correction. They still stated that it would cost Rs48,000 crore and not more than Rs60,000 crore.
This is being mentioned here primarily to bring on record that having got clearance in principle from the Government of Maharashtra (GoMah) for the entire MMMP at Rs19,525 crore and Detail Project Report (DPR) for Line 1 presented to GoMah and obtained its approval to proceed with tendering and award, it looks like MMRDA did not feel that they should brief up GoMah and the citizens of Mumbai the fresh cost projections subsequent to Line 1 award.
Also, though the DPR was fairly comprehensive, it did not bring to light directly the performance criteria emerging, i.e. the capacity of the line to handle peak period commuter traffic.
With the knowledge of site conditions due to underground utilities, as experienced in the construction of pedestrian grade separation subway at Metro Cinema Junction in the island city (i.e. South Mumbai), even the construction time delays one could anticipate and consequent hardship citizens would have to bear was not a surprise sprung upon all of a sudden. Therefore MMRDA should have informed GoMah as well as citizens on this score as well. Additional effects on costs could take it to Rs1,00,000 crore and if the entire Metro were to be underground, the costs could be more than Rs1,50,000 crore.
The MMRDA strategy seems to be to keep the three points mentioned from being brought before the Cabinet once again and also keep citizens in the dark, this way MMRDA could continue with getting line by line approval for the Metro.
To recall these points:
(i) Costs enhancements (not escalation) being more than three times of the original estimate presented, touching five times or for full underground more than eight times.
(ii) Capacity being infused to unburden the load on railway system being significantly inadequate even at present, leave aside when completed say 30 years later and
(iii) Duration of construction for the entire project being grossly underestimated could be more than 30 years.
There has been strong opposition to Line 2 being elevated. Residents in the Bandra to Juhu area and the commercial establishments have demanded underground Metro while slum residents at Charkop (Laljipada) where the car shed was planned, have taken exception to MMRDA selecting their slum for this and forcing eviction on them while land was available not too distant away from their slum location. Also, the area sought by MMRDA for the car shed was significantly more than what was required for the actual car shed, thus displacing slum dwellers in very large numbers. Hidden agenda can be visualized in terms of developing slum area thus acquired for realty. The status for this is that the Charkop Car Shed has been relocated.
For Line 2, MMRDA has been insisting that the cost of underground line is exorbitant and hence they have no option but to go with elevated Metro while in the island city every line is underground. Double standards are being applied to the island city and suburban Mumbai. The Bandra to Charkop stretch runs on an arterial road having enviable foliage, which also will fall prey to the elevated Metro.
Professor Dhingra of the Transportation Engineering Division at IIT Bombay was engaged to give a comparative impact analysis of the elevated and underground Metro alternatives. His report clearly concludes that given the two alternatives, underground Metro has much greater advantages than the elevated. Also, given the construction delays in Line 1, this arterial road getting delayed will cause untold hardships to the neighbourhood citizens as well as other users of the arterial road.
Fig 1 shows the nine routes proposed along with the proposed period of implementation as envisaged in 2004. Construction having commenced in 2008, just 11.4 km Line 1 out of Phase I's 63.8 km is under construction as of 2012 and is expected to be completed by the end of 2013. Indications are clear that the full MMMP will take nothing less than 30 years. Going by the speed of construction of Line 1, i.e. about 2.3 km per year, it should take about 64 years! These are of serious concerns, especially considering that the alignments are along the arterial roads which cannot all be blocked simultaneously, as there is great road congestion as it is.
Very recently the Line 3 which had the alignment from Colaba to Bandra was altered from that to Colaba to SEEPZ via Bandra Kurla Complex (BKC) and Airport Terminals as shown in Fig 2.
A social and environmental impact assessment study is being undertaken as per JICA guidelines by MMRDA. In this regard the alignment and station locations have been notified by advertisement in media and on the MMRDA website.
Suggestions/objections for the same were invited from concerned stakeholders in writing by Mumbai Metro Rail Corporation (MMRC), the SPV formed by the Government of Maharashtra for implementing Metro Rail projects in Mumbai. Notification comprised of what is limitedly mentioned in Fig 2 and Fig 3.
Going through the DPR of the original Line 3, one could say that the capacity of a line would be 18,000 passengers per hour per direction (pphpd) initially and 36,000 pphpd ultimately. MMMP has two routes South to North, one running from Colaba to Dahisar and another to Mulund, giving an ultimate capacity of 72,000 pph. When MMMP is fully completed, the Dahisar-Andheri line will add another 36,000 pph capacity.
Broadly speaking, the load on suburban system in the peak time tidal direction is about 3,60,000 pph. The current design capacity of the railway system is 1,60,000 pph which will get enhanced to 1,80,000 pph when current phase of MUTP gets completed in 2015. Thus from 2015, the deficit in public transport capacity will be to the tune of 1,80,000 pph. However, MMMP will provide only 72,000 pph south of Andheri and additional 36,000 in the north of Andheri only when the entire MMMP gets completed, 30 years later, when the load would have probably increased further.
To finance the nearly a lakh of crore rupees project, FSI enhancement is being considered and given the general income levels and economic conditions, there would be many who will have to avail of new premises brought into the market at extremely high rates of realty, thereby needing further capacities of public transport. It is a vicious circle. The long duration of construction is also going to get more than two generations of citizens subjected to tremendous hardships and as numbers tell, without any respite there after either.
LINE 3 of Mumbai Metro
The notification to public, seeking their suggestions and objections comprised of what is provided in Fig 2 and 3. It provided a month to the public to submit these.
Information provided is inadequate for public to react and there were no reactions to it. But following could be inferred or questioned:
1. The Line 3 has 27 stations in 33.5 km length, giving an average station spacing of 1.24 km.
2. A six-coach train will require about 135m of station length
3. It is presumed that access to station platform will be through staircases, escalators and elevators. Their location on the roads would curtail the road pedestrian movements significantly unless the DPR has shown how it will not.
4. DPR is not available for comments.
5. At what depth would stations be and if they are at higher levels, then what is the method of construction envisaged?
6. It is assumed that Tunnel Boring Machine (TBM) will be used to bore the tunnel. Where would the TBM inserted into ground to commence boring and how would the excavated material removed and disposed off?
7. How would the rakes be stabled? Where would the cars shed be located?
8. What are the methods of providing ventilation and air-conditioning? Power requirement, how will this be met?
9. What are the disaster mitigation plans and disaster management plans?
10. There is a seismic fault line passing through the geological structure of Mumbai. How have they addressed this issue?
11. Unlike the earlier Line 3 alignment which was going through the erstwhile mill areas of the island city that did not have railway line, the new alignment avoids that completely and runs almost parallel to the Western Railway line till Mumbai Central and Mahalaxmi stations. Intention may have been to bring it closer to Malabar Hill and Cumballa Hill where personal motorcar usage is very high. However it is highly unlikely that personal motorcar users will use the Metro if the stations are not passing very close to their dwellings. The route needs to be reviewed from an overall perspective of reducing personal motorcar usage.
12. There is no mention of how stations will be fed with commuters or how they will be dispersed. Whether they propose to provide for parking cars and if so, the very purpose of providing public transport through Metro gets defeated if one provides these car parks. Firstly these will be totally inadequate, forcing people to either park on road sides or use cars for full distances.
There are other high cost road projects being considered, but nowhere mention is being made of BRTS which can be implemented in briefest time and meet the requirement of Mumbai's Transportation.
MMRDA is the planning agency of Government of Maharashtra and it is to plan for transportation as a whole. But ever since it was given the responsibility of implementing the big ticket projects of Metro Rail and Monorail, it is ceased to look at planning as such and the low ticket sustainable option of BRTS in particular. This is in total contravention of norms that make a city livable-for those living now and for those living in future.
