Mumbai Trans-Harbour Bridge : Nhava-Sewri Sea Link

[pkalein]

Now I think no one is going to use it

[Indiadreams]

It is quite funny. The predictions and the toll rates are not rounded off.

Number of vehicles - 44975 (why not make 45000, are they sure of this exact number

Car - 182 bucks. Bus - 432 bucks

Are they going to watse timein giving back the change each time at toll booth??

Mumbai Trans-Harbour Bridge : Nhava-Sewri Sea Link
ki kam bhi shuru hui ya nahi......

[MYSTIC]

Isn't Rs.8800 cr a lot of money for a bridge. How come the one's China are made at such low cost?

[jaadu]

which bridge are you talking about in China ? I think for this type of bridge its not a lot of money actually !!

cheap labour... and "great chinese quality "

[dunefreezer]

I think 1.76 billion dollars is acceptable for a massive bridge like this one.

Of the six consortia that have submitted proposals to build the Sewri-Nhava Mumbai Trans Harbour Link (MTHL), all are likely to qualify for submission of final bids to construct the bridge, which has been talked about for more than three decades now.
The Mumbai Metropolitan Region Development Authority (MMRDA) last year re-initiated the project — which has had a few false starts — by calling for pre-qualification proposals from companies.

A total of 17 companies representing various consortia had shown interest while six ended up submitting the proposals. “We had a meeting yesterday to discuss the proposals and it looks like all the companies will qualify for bidding,” an MMRDA official said.

The consortia that have submitted pre-qualification bids are CINTRA-SOMA-SREI; Gammon Infrastructure-OHL Concessions-G.S. Engineering ; GMR Infrastructure-L&T Ltd-Samsung C&T Corp; IL&FS Transportation Networks-Unity Infrastructure-Navayuga Engineering-Rizzani DE Eccher; IRB Infrastructure Developers-Hyundai and Tata Realty and Infrastructure-Autostrade Indian Infrastructure Development-Vinci Concessions Development.

“We are looking at the experience of these companies, their net worth and the kind of projects executed by them in the past in detail. All the companies have world-class qualifications,” Rahul Asthana, metropolitan commissioner at the MMRDA said.

“We would be announcing the list of consortia qualified to submit final bids within 15 days,” Asthana added.

The 22-kilometre-long MTHL, which will also include the longest sea link in the country, has gone through two failed rounds of tendering when it was being implemented under the Maharashtra State Road Development Corporation (MSRDC).

In June 2008, bids submitted by the Ambani brothers was found unrealistic, and ultimately did not work out. The second time, the MSRDC tried to execute the project as a cash contract. Thirteen companies had shown interest, but did not submit bids. The mandate was later handed over to the MMRDA.

This time, the MMRDA, which is implementing the project on a public-private partnership model, plans to pick a contractor by November and start the construction next year. The construction is expected to take five years.

The Sewri-Nhava Mumbai Trans Harbour Link (MTHL) could give the city its third cable-stayed bridge after the Bandra-Worli Sea Link and the under-construction Versova-Andheri-Ghatkopar Metro corridor.
Although costly, a cable-stayed bridge is useful for stretches where the span, or the distance between two piers, is longer than usual.

According to structural specifications by the Mumbai Metropolitan Region Development Authority (MMRDA), there are four stretches on the MTHL that will need longer spans to overcome navigational challenges. The MTHL walkthrough prepared by the MMRDA shows the use of a cable-stayed bridge on these stretches.

“The walkthrough is indicative. A cable-stayed bridge can be used for that portion. The other options are using a balanced cantilever bridge or an extradosed bridge. The decision on which bridge to build depends on the consortium constructing the MTHL,” an MMRDA engineer said.

A cable-stayed bridge is built with one or more columns called pylons with cables supporting its deck, while a balanced cantilever bridge has two well-anchored arms and one span between the arms, creating an arch-type structure. An extradosed bridge is a combination of a girder-based and cable-stayed bridge.

“A balanced cantilever bridge would be more cost-effective compared with the other two types of bridges,” the engineer said. The Vashi bridge built over the Thane creek to connect Vashi and Mankhurd uses the balanced cantilever method of construction.

The four stretches on the MTHL in need of longer spans are Pirpau jetty, requiring five spans of 120 metres each; HPCL requiring two spans of 120 metres each; Thane creek with two spans of 170 metres each; and Panvel creek with two spans of 170 metres each. The average span is otherwise about 50 metres.

Mumbai’s first cable-stayed bridge was a 500-metre-long structure built as part of the Bandra-Worli Sea Link, which was opened in 2009. The Versova-Andheri-Ghatkopar Metro will have the second such bridge — a 175-metre long structure across the Jog flyover on the Western Express Highway.

The MMRDA had proposed to build another cable-stayed bridge over the Manori creek but the project is currently on hold due to environmental concerns.

The 22-km MTHL, estimated to cost Rs 8,800 crore, is going through a third round of tendering, having seen a poor response the first two times. This time, six consortia comprising 18 companies have submitted proposals to build the project, which will boast of the longest sea link in India.

I am talking about the Hangzhou Bay Bridge. It cost the same amount but the Chinese bridge is much longer.

[Vicky007]

Come on men, you can never trust any of the figures that come from China. Not for nothing has it got the sobriquet - Shanghai Statistics.

I think the total cost of the project has to be higher .. anyways you need to see what the cost includes .. just the bridge or the approach roads, rehabilitation etc. , then where the bridge is .. how is the soil and geologic conditions , how deep or high the pillars need to be.

The eastern section of the bay bridge in San Francisco is being built right now .. it has a length of around 2-3 kms but the cost is 6 billion dollars !! The reason being that it is being made to a specification of surviving the biggest earthquakes in the region .....

May be someone more knowledgeable here could explain this in more technical terms !!

- Comparing construction costs across countries is quite difficult because significant differences in labor and material costs to begin with, not to mention the speed of execution and the complexity and cost of permitting. For example, the cost of constructing a commercial office building in the US could be higher than USD 500/SF whereas the comparable figure in India is about USD 50/SF!

Comparing MTHL to its closest existing cousin, the BWSL, the cost figures seem quite realistic taking into account its much greater length and complexity.

Plus, the amount of subsidy in various materials in China can never be made out. Heck some of it may even be free coming in from State mfg units!!!

Hi guys
I recently joined SSC and subscribed to NMumbai related forums (MTHL and NMIA). Lots of good and interesting information I found in here.
The information that I have so far about MTHL location is that it is going to connect Sewri with Nhava and going to further stretch upto Khopoli via Chilre. However I could not find the map showing exact path it is going to be upto Khopoli. I also could not locate Chirle. I would appreciate if anyone can point me to the right direction or display the map.
Best regards,

[Coolguyz]

Its actually Chirle. It a small village at the interchange of NH4B on NHava side.I.dont think they ar building a new alignment upto Khopoli. They will b joinin MTHL to NH4b which further meets NH4 to pune or NH17 towards goa

Guys it seems that trans harbor link tendering process is over and the name of the winner is out according to:

Trans-harbour link project: Firms on shortlist for infra plan to be made public
MUMBAI: The prestigious, Rs 8,800 crore trans-harbour link project is set to get a boost on Thursday. The Mumbai Metropolitan Region Development Authority (MMRDA) will shortlist the firms eligible to carry out the work on the 22-km link, the longest sea bridge in the country.

MMRDA commissioner, Rahul Asthana said the list will be made public on Thursday after a meeting of the screening committee. MMRDA officials said that the final run for bagging the project will then begin. The MMRDA received six proposals involving 18 companies for the pre qualification bid held in March. A screening committee was set up to examine the eligibility of the proposals which had several big international names. An international consultant, KPMG has been helping the MMRDA officials go into all the details of the screening process.

Among the big names in the fray are Gammon Infrastructure Projects Ltd,OHL Concessions and G.S.Engineering Consortium, GMR Infrastructure, L&T Ltd and Samsung C&T Corp,Tata Realty and Infrastructure, Autostrade Indian Infra and Vinci Concessions. The link will be 22 km long with a 16.5 km long bridge across Mumbai harbour and a 5.5 km long viaduct approaches on the Sewri and Nhava sides. Interchanges are proposed at Sewri to connect to Eastern freeway and at Chirle to connect to National Highway 4B to facilitate traffic dispersal.

The state government has tried to start work on the trans harbour link for several years without anything definite coming about.The attempt by the Maharashtra State Road Development Corporation(MSRDC) to invite tenders and begin work did not materialize and the work was handed over to the MMRDA by the state government recently.

MMRDA officials said that the work of screening has been going on for the past two months. Past record and the technology being offered by these companies will be a big plus point in assessing the winners.

MUMBAI, MAY 10:
The Mumbai Metropolitan Region Development Authority (MMRDA) has short-listed five consortiums to develop the Rs 8,800-crore Mumbai Trans Harbour Link.

The five are Cintra-Soma-Srei, Gammon Infrastructure Projects-OHL Concessions-G.S. Engineering; GMR Infrastructure- L&T – Samsung C&T Corpn; IRB Infrastructure Developers – Hyundai and Tata Realty and Infrastructure – Autostrade Indian Infrastructure Development – Vinci Concessions Development

MMRDA said the consortiums will be provided with bid documents (request for proposal (RFP)) once they are generally approved by the Union Government. They will also be issued copies of draft feasibility report, previous studies and surveys, if asked.

The RFP requires the approval of the Centre as it will offer 20 per cent viability gap funding for the project.

The project will be through public-private partnership on design, build, finance, operate and transfer (DBFOT) basis.

The shortlisted consortiums are expected to finalise designs, technical details, financial details, actual survey of project site and prepare their bids around October.

The 22-km Trans Harbour Link will connect Sewri in the island city to Nhava in Navi Mumbai. It will have a 16.5-km bridge across Mumbai harbour and 5.5 km long viaduct approaches on the Sewri and Nhava sides.

Interchanges are proposed at Sewri to connect to Eastern Freeway and at Chirle to NH 4B to facilitate traffic dispersal. The project involves construction of the longest sea bridge in the country.
