MUMBAI: Mumbai Metro Rail Corporation (MMRC) on 22nd April achieved 37th breakthrough at Chhatrapati Shivaji Maharaj Terminus (CSMT) Metro Station out of the total 41 breakthroughs planned for the 33.5 km long Colaba-Bandra-Seepz underground line (Line-3) of Mumbai Metro.

The contract for this work under Package UGC-01 was awarded to the JV of Larsen & Toubro and Shanghai Tunnel Engineering Company which operates Tunnel Boring Machine (TBM) Surya-2 for the construction of tunnels and four stations at Cuffe Parade, Vidhan Bhavan, Churchgate & Hutatama Chowk.

According to MMRC, TBM Surya-2 completed its final drive of 569 meters from Hutatma Chowk to CSMT Metro Station in 106 days using 418 concrete rings. With this 2.9 km long downline tunnel from Cuffe Parade to CSMT Metro Station is completed.

“Tunnelling in the heritage precinct, which is also in the close proximity to the sea, is a daunting task. MMRCL team of contractors, consultants, engineers and workers scientifically dealt the challenge successfully. I am happy that 96% of tunnelling has been completed in package-1 by ensuring the safety of the historical buildings”, said Mr. Ranjit Singh Deol, Managing Director, MMRC.

With this breakthrough, 52 km of tunneling is completed out of the total length of 54.5 km which is approximately 95% of the total project.

The issue regarding construction of car shed for Mumbai Metro Line-3 is still not resolved as the Bombay High Court is yet to decide whether the salt plan land in Kanjurmarg, where the metro depot is proposed to be constructed, belongs to the Centre or State.

The 9 KMs long elevated Priority Corridor between IIT Kanpur and Motijheel is being constructed under the Kanpur Metro Rail Project. Last night another ‘Steel Girder’ was erected at Rawatpur Tiraha. In this span the first ‘Steel Box Girder’ was placed on March 27, 2021. These girders are of 45m length, assembled near the location and erected by cranes in the night on the busy crossing.

On this occasion, Managing Director, UPMRC, Shri Kumar Keshav said, “In view of heavy traffic at Rawatpur, it was planned that no Piers should come in the middle of Rawatpur Tiraha and due to this the distance between the two Pillars was increased up to 45 meters in this section. This is the reason that in this span two specially designed light weighted ‘Steel Box Girders’ have been placed instead of U or I-girder. UPMRC always strives to ensure that the Metro Corridor is planned and is executed in such a way that traffic movement doesn’t get affected.”

Three locations have been identified between IIT and Naubasta (Corridor-1), where Steel Girders are to be laid. The first Steel Span has been placed near Rawatpur, the second will be erected at Sisamau Nala and the third one near Vasant Vihar.

Why ‘Steel Box Girder’?

• It was not possible to place a U or an I-girder of this length at the said span hence ‘Steel Box Girder’ has been introduced.

• The length of the steel girder is longer than the U-girders that are being used in the Corridor but relatively lighter in weight. It is also to be mentioned that the length of the referred steel span is 45 meters while U-girder has an average length of 27 meters. A 27-meter U-girder weighs about 147 tons, while 45-meter Steel Span weighs about 120 tons.

• Three locations have been identified between the 23KMs long IIT & Naubasta stretch in where Steel Girders are to be laid. The first Steel Span has been placed near Rawatpur, the second will be erected at Sisamau Nala and the third one will be placed near Vasant Vihar. Separate steel girders are to be laid for up-line and down-line.

Each 45-meter long steel girder is being prepared by connecting 5 segments.

MMRDA has invited bids for this work multiple times while originally in 2017 contract for this work was awarded to RCC Infra Ventures Limited but the contract was terminated in January 2020 due to poor progress of work.

Last time when MMRDA invited bids for this work, NCC Limited emerged as the lowest bidder (November 2020) quoting bid value of INR 719.27 Crores which was way above the MMRDA estimated cost of INR 568.55 Crores and further negotiations between the two did not result in any positive outcome leading to re-inviting of tenders.

Now it remains to be seen how the work progress on this section of Mumbai Metro Line-2B as work is already got delayed. Hopefully, this time tenders invitation will culminate to starting of construction on the given section which will take another few years before operations of metro trains start on this section.

There is also a proposal to build three iconic bridges on this 23.64 km long Metro Line 2B from DN Nagar to Mandale. The designs for the bridges are already ready and tenders were floated for the second time in June 2020 for their construction. The bridges to be constructed are Arch shape bridge over Mithi River, Zero shape bridge at Vakola Nala and the Sword shape bridge at BKC Entry. The purpose is to give aesthetic look to the surrounding areas through these all three cable-stayed bridges. Mumbai will look more beautiful through these bridges and the bridges will be visible from far distances creating new skyline for the city. Hopefully, construction of bridges will start at the earliest to add another jewel to the city that never sleeps.

New Delhi, April 23, 2021– The Linear Railway infra projects require high accuracy surveys to achieve designed track alignment. Given the design speed of 180 kmph on the structure either elevated viaducts or underground tunnels, there is no scope for fault in the construction of RRTS structures and tracks. The NCRTC is using “Continuously Operating Reference Station (CORS)” technology to ensure accurate civil structure alignment in the construction of Delhi-Ghaziabad-Meerut RRTS Corridor.

 
CORS- Continuously Operating Reference Station – is a global positioning system (GPS) based technology mainly used in surveys, mapping, and allied services. This technique ensures complete accuracy in the construction of a predetermined corridor in civil construction so that the planned alignment can be achieved.

Delhi-Ghaziabad-Meerut is an 82 km long corridor going over rivers, railway lines, roads, expressways, and flyovers. Hence it is very important to maintain accuracy in civil structure alignment. Keeping this in mind, the NCRTC went beyond the traditional technologies and adopted an ultra-modern survey technique, CORS, which is being used for the first time in the country in any mega infrastructure project.  

CORS is a network of ‘reference stations’ that are established at every 10-15 kilometers along with the Delhi-Ghaziabad-Meerut RRTS corridor, these CORS ‘reference stations’ are connected to the “Control Center”, which provides the real-time data to the rovers collected from 3-5 reference stations. The entire process of data collection enables the rovers to achieve accuracy of up to 10 mm.

Also, given the limited timeframe for the implementation of the country’s first RRTS project, the construction work is in progress at multiple sites simultaneously. To ensure that construction at multiple locations does not impact the accuracy of the project, CORS is being used as it mitigates the risks of any kind of error during the construction. The CORS network is set up for the first time in the country for a rail-based project, the system is set to be a path-breaking system for such projects to conduct surveys.

This tender work is a part of project related to doubling of 342 km long railway track from Hospet in Karnataka to Vasco-da-gama in Goa. According to Ministry of Railways, the project has nearly completed in the state of Karnataka except 10 Km between Unkal and Hubballi stretch which was expected to be completed in March this year.

About 7 km track between Madgoan- Majorda in the state of Goa has also been doubled. Remaining stretch of about 90 Km is in the State of Goa, where works are awarded for doubling and are being taken up after ensuring necessary clearances.

Doubling of the said section will be a game changer for the state of Goa, taking the development to new heights, by giving impetus to trade and enabling easier and faster passenger movement. Existing rail network is constrained due to single line long ghat sections severely limiting train running capacity.
