The Navi Mumbai Metro, presently on the fast track, is the project that will befit the
tradition and reputation of the projects so far completed by CIDCO – from the housing
complexes to railway station complexes and from Navi Mumbai International Airport to
Golf Course. Based on the master plan of transport system the project’s main aim is to bring
multi-dimensional transport system near completion. It will facilitate the future pace of the
CIDCO’s endeavour is to take railway tracks to every node. It has done it in most
parts of the city in coordination with the Indian Railways. However, due to non-availability
of enough land or pre-planned reservations for different usages CIDCO was unable to follow
stringent norms of the Indian Railways in some sectors. Metro has provided the solution to
CIDCO appointed the Delhi Metro Railway Corporation for preparing the feasibility report.
The report was positive and the DMR suggested five such routes in the city. On receiving the
report CIDCO pressed into service and studied existing Metro projects in India and abroad
with a view to giving the best possible things to the people of Navi Mumbai and to ensure
the project will be another milestone.
CIDCO then appointed Louis Berger, vastly experienced in implementation of
Metro Projects, as General Consultant to prepare a robust mechanism for successful
mplementation of the project. Even the resourceful firm of international repute had to go
through competitive bid process. Complete transparency was maintained. Corporation has
also formed teams of experts to oversee the Project implementation.
The Government of Maharashtra, on 10th September 2010, appointed the corporation as
an agency to implement and project. CIDCO decided to take up the first phase of Belapur to
Pendhar, a stretch of 11 km for development. Chief Minister Mr. Prithviraj Chavan laid the
foundation stone of the project on the 1st May 2011 and set three years timeframe for the
project even as it was initially slated to be completed in five years.
Probably going by the track record of the corporation the Mr. Chavan had instilled
the confidence in the administration. To live up to the expectations of the CM, Managing
Director Mr. Tanaji Satre has been keenly following the progress of the project since
its inception. He often visits sites and has so far conducted 60 review meetings of the
concerned officers, staff and the agency authorities. The project kick-started with selection
of agencies for civil works.
The Corporation has launched www.navimumbaimetro.coma dedicated website for
the project giving all the update information including the status of the ongoing work. Thus
the project maintains complete transparency at every stage. This is the unique step to keep
all the stakeholders abreast of every activity of the project.
A model for all the elements of the work in 3D environment has been prepared
using Revit and Tekla softwares has been assigned to professional agency to estimate
quantity expeditiously. This model will finally give all 2D AutoCAD drawing generated at will.
This will facilitate monitor work progress closely.
Quality and Safety
Not withstanding any hardship and towing in the principle of not compromising on quality
CIDCO’s technical experts studied national and international projects and set its own
parameters. They have left no stone unturned in the planning of Metro Rail covering all
aspects of efficiency and power saving making it near full-proof.
A lot of stress has been given to the aspects of safety and quality in the entire
project and accordingly provision of Independent Quality Auditor and Independent Safety
Assessor has been made in the final bid package of Metro Systems and both will work for
safeguarding interest of the Corporation.
Coach Width Increased
The first technical change effected is to increase the width of rolling stock from 2.9 Mtrs to
3.2 Mtrs. The DMRC wholeheartedly endorsed this decision. The prudent step was taken to
seamlessly integrate Navi Mumbai Metro with the Metro Systems of Mumbai.
With a futuristic view the 750 V DC electrical power supply system was replaced with
25000 V AC system which has advantages of requiring less number of traction substations
and consequently less land was adopted.
The communication system of Audio Frequency Track Circuit (AFTC) changed to adopt CBTC
the best available system so far. The AFTC, being track related it is susceptible to weather
and due to high copper content it is also prone to theft. Further data communication with
central control unit is not bidirectional, whereas CBTC communication is more reliable and
bidirectional with central control unit.
Energy saving is high due to accurate train localization. With CBTC the final headway,
distance between two trains, can be as low as 90 second and this has significantly enhanced
ultimate carrying capacity of the system to 65000 PHPDT.
Automatic Fare Collection will be a closed system with automatic gates at all
stations. For single journey, smart tokens and for multiple journeys, stored value smart
cards have been proposed.
The Progress so far
While inviting bids for civil works the scope was broadly divided into three parts
namely Viaducts, Stations and Depot. The scope of Viaducts and Stations was further split
into two parts so that the risk of non-performance by one agency jeopardizing the project
time schedule is minimized and option of switching over the work responsibilities to other
agency in case any eventuality takes place.
Piers compilation is the daunting task as it requires solid foundation for the vital
structure entirely bases on them. It also requires more space for the machinery and
equipments. Taking the facts in to account two agencies have been appointed for the work.
So far compilation work of 86 piers has been completed.
To catch up the speed that almost runs against the time Station Development, Depot
Development and System Development activities have take up simultaneously. The process
of tendering and agency appointment for Station Development and Depot Development is
complete. Process of System Development is in progress.
