Metro 3 corridor will benefit 30 lakh population along the corridor and will carry 17 lakh passengers per day

 

 

Mumbai Metro Line - 3 (MML - 3) is one of the key projects to improve the transportation scenario in Mumbai the financial capital of India. MML-3 project - a 33.5Km. long corridor running along Colaba-Bandra-SEEPZ, envisages to decongest the traffic situation in Greater Mumbai. It aims to provide a Mass Rapid Transit System that would supplement the inadequate suburban railway system of Mumbai by bringing metro closer to the doorsteps of the people. With full-scale operations of MML-3, the city would witness significant reduction in traffic volumes and the local transit facility would get a boost. Mumbai Metro Line 3 project is to proudly herald in a new era by making the travel in Mumbai a comfortable, reliable and pleasurable experience. ASHWINI BHIDE, MD, MUMBAI METRO RAIL CORPORATION spoke to CONSTRUCTION OPPORTUNITIES on the current status of the project, its impact and opportunities.

 

 

Please brief us on the current status of the metro rail project?

The construction work of Mumbai’s first underground Metro Colaba-Bandra-SEEPZ Metro-3 has been divided in to seven civil packages. Contracts for civil work of all packages have been awarded in July 2016.Geo-Technical Investigations, Barricading, Building Condition Survey, Trial Trenching work, Environment Baseline Surveys and temporary earth retaining at all the Tunnel Boring Machine (TBM) launching shafts location are in progress in all the packages. More than 400 secant pilings have been completed in all seven civil packages. 125 major equipment’s/ plants have been deployed at construction sites. Around 1700 manpower have been deployed for this project. Tendering process for all system packages including Traction/Power supply, Tunnel Ventilation System, Lift & Escalators, Rolling Stock, Signaling and Train Control, Platform Screen Doors, Telecom System, the Automatic Fare Collection (AFC) System is in progress and will be concluded by the end of this financial year.

 

 

What are the expected long term impacts and opportunities from the project?

Metro-3 aims at protecting Mumbai’s environment in the long run by reducing 6.5 Lakh vehicle trips per day and in turn by reducing carbon footprint. Also, it will reduce 3.35 Lakh litres fuel consumption per day. Metro-3 will help in reduction of congestion on suburban railways by 15 per cent. Once commissioned Metro-3 is likely to reduce emission of CO2 and other greenhouse gases to the tune of 6800 tonnes per year in the year 2021.Apart from this the project will generate 5,000 jobs during construction and 2,000 jobs post construction.

 

 

How will construction of Metro rail project impact the community?

Metro 3 corridor will benefit 30 lakh population along the corridor and will carry 17 lakh passengers per day. It will provide connectivity to the areas which are hither to unconnected by suburban railway. It will also provide the connectivity to domestic and international airports, 30 educational institutes, 13 hospitals, 14 religious places, 30 recreational centres and 6 Business Development Centres.

 

 

Expected cost of the project and funds disbursed so far?

Total project cost as per the Detail Project Report is Rs.23,136 Cr. MMRCL, a JV of the Government of Maharashtra and the Government of India has 10.4 per cent of equity of both state and central government. JICA will provide 57.2 per cent soft loan. The remaining funds will be provided by both central and state governments. Also, the stakeholder MIAL will contribute Rs.777 cr. for building three stations of Metro-3 at airport complex. MMRDA will pump around Rs.700-800 cr. by way of grant and through commercial development MMRCL will generate Rs.1000/- cr.

Any interesting highlights or features which distinguish this project from other metro rail project?

Metro 3 corridor provides connectivity to Mumbai International and domestic airports even though it is not a dedicated airport express.

 

 

What are the challenges specific to this project?

This is first underground Metro project and possess a number of challenges. Hard rock, high water table and tunnelling in congested areas will pose the challenges while construction of Metro-3 however, with the help of advance technology and team of experts MMRC will surmount the problems. Rehabilitation of project affected families is one the challenges.

Around 2,800 families are affected by project, out of which around 900 have been rehabilitated. Transparent lottery system is followed for allotment of tenements to PAP’s.

Social and Economic development initiatives and employment oriented training programmes will be arranged for project affected families. The State Government has approved in-situ rehabilitation and redevelopment plan for 652 PAP’s of Girgaon and Kalbadevi.

 

 

How do you justify cutting trees for a Metro?

Metro-3 is a huge project worth Rs.23,000 Cr, which will be implemented over 4 years and will serve the city for the next 100 to 150 years. In a congested city like Mumbai trees need to be cut for various types of development including real estate development.

However trees cutting for public transport project is justified since environmental benefits are larger than temporary loss on account of trees cutting. Mitigation measures like compensatory tree plantation help substantially in reducing the losses due to tree cutting. Conflict of saving trees over construction of public transit infrastructure for a metropolis needs to be resolved with prudent decision to achieve a larger goal.

 

 

What are the green initiatives taken for the metro project?

  • Use of Solar Plant for at grade station and depot.
  • Providing energy savvy Glow Signages.
  • Harvesting day natural light.
  • Improved Regenerative braking for carbon neutrality.
  • LED based smart lighting & smart AC in coaches.
  • Use of state of art variable voltage variable frequency (VVVF) elevators, escalators and travellators with concept of regenerative drives.

 

 

Detail us with regards to the latest technologies like construction equipment, software, building materials etc. being used in the metro rail project.

The 33.5 Km long fully underground corridor has two aspects of construction. One is tunnel and other is the station.

Tunnelling will be done with the help of TBMs and stations will be constructed by using cut and cover method and New Austrian Tunnelling Method (NATM). Metro-3 will have 27 stations of which 26 stations will be underground and 1 station would be at grade.

19 stations will be constructed by using Cut and Cover method while 7 will be constructed by using NATM. There will be platform screen doors, CBTC signalling system and automation grade 4 level driverless trains.

 

 

Future outlook.

MMRC is committed to complete the project by 2021.
