Mangalore: New Bridge Girder Breaks Causing Heavy Loss, Traffic Chaos

"If the girder could get damaged so easily by falling from the low height of the truck, what would be its quality and that of the bridge? would like to meet this person who said this, there is a huge difference in making a LOAD Bearing truss and a Impact bearing one, what is generally used in bridges in Load Bearing, any civil enggs gurus in the forum pl enlighten.

Does it make sense, carrying long and heavy weighted of solid concrete on such vehicle?

Dear bcd, Mangalore, I can understand that being involved in the construction of bridges your knowledge is no match to any one. Surely there is no cause to fear had this bridge is constructed in high degree of standards and specification as you briefed. Who is saying girder fell down due to poor quality? it is not. Girder fell down due to vehicle failure, but broke apart due to poor quality of the material or workmanship. Do you think this girder should break when falling from height of hardly 1.5m of trailer? See the flakes of broken uncured concretes in the picture. Its not only in this picture you may see lots of unprotected exposed steels, honey coumbs, irregular broken edges, improper shuttering... etc on the girders which have already installed. It is immaterial knowing or having higher quality standards, but actual implementation is important which is lacking in this bridge construction.

The people who are commenting about the quality of the concrete used in the girder doesn't know the technical view. The concrete used is of high grade concrete and it is prestressed girder. the girder is designed to take the vertical load & not the hor. load, for that after placing at location the girders will be interconnected with diaphragms to make it a complete unit before casting of the deck slab. Also the steel used is Fe500 and the prestressiing steel used is Low carbon steel made by TATA Special steel, this steel properties an ordinary person can't understand. Also the girder is casted and prestressed under strict quality control and supervision.
The girder fell only because of the failure in the jacking system of the transportation trailor and not because of the quality. If there is any quality flaw of concrete the concrete can't take the prestressing force which is induced in to the concrete.
One can't blame the driver if the tyre punctures during the midway while travelling, that quality of the tyre is not good!!!!!
One should not fear anything for the quality of the concrete and the structural stability of the bridge, it is built to the highest standards and specifications with the state of the art concrete grade and steel.
I personally as a technical person involved in the construction and supervision of Bridges in the nation like Bandra worli sea link bridge, Mumbai, PV narasimharao elevated expressway in Hyderabad and various other structures do not agree for various comments reflected in terms of the girder fall do not agree for hurling demotive comments on the contractor.
In view of the above no one should fear about the construction quality and other permanent works involved in the project construction.

Hello Mangalorean, wake up you people are ready to fight each other for silly matters,now wake up and go ahead to save life. You can see the poor quality of work. Comon BD, Sene and Nithika Police now you are sleeping, hold matter and take the right authority for quality checking.

Dinesh shetty, Mnglr
Very rightly said,You have given useful information about the quality....

It looks the proportion of mixing cement with sand got miscalculated for this girder.Say a wake up call for the concerned dept,a quality check is missing? knowingly or unknowingly in the project?

Mr AV ,This one is central government project.I think you have your knowledge.Please find out the owner of navayuga company too.All political parties are same.But you should be wise enough to decide.Please,before commenting anything study properly.

THIS GIRDER IS LIKE BJP. FULL OF CRACKS AND EASILY COLLAPSABLE. I AM SURE BJP GOVERNMENT MADE MONEY OUT OF THIS BY COMPROMISING ON THE QUALITY AND TRY TO TAKE THE PEOPLE OF KARNATAKA ON A RIDE. THIS KIND OF FOOLISH AND CORRUPT GOVERNMENT SHOULD RESIGN IMMEDIATELY RATHER THANK PLAYING WILL THE LIVES OF MILLIONS OF INNOCENT PEOPLE. NO PLACE FOR CORRUPT GOVERNMENTS TRYING TO FOOL THE INTELLIGENT PEOPLE OF THIS COUNTRY BY PLAYING WITH TAX PAYERS MONEY.JAI HO INDIA. JAI HO KARNATAKA.

if this is the case no one will go by new bridge because of poor quality. people will use old bridge for both ways ,contractor must be charged for such incident

Dear Readers, please note that a concrete girder is not flexible but is very stiff.If the girder was constructed as per high industrial norms, then it can take tremendous compressive force, but not a suddenly applied load as happened here.

Also, I find it very strange that the girder was fabricated somewhere else and was being transported to be installed on location.

Mere flexing of the trailer chassis could cause minor or major cracks, which may cause the girder to collapse in the future.

The girder should have been fabricated as near to the final location as possible.

the truth of the bridge's quality is exposed, what as happened is really good.

Mr.STEVE, MANGALORE

Even though it's of sub-standard - nothing is going happen to mangalore due to 'Parashurama Shristi'. You people always fall in blame category.

Nice coverage by Daya and keep it up. These pictures will be a prrof how these guys work. I think the trailer could not bare the weight of the heavy girders. From the pictures I can guess that the roads have become bad and the trailer must have tilted to one side causing the girders to fall. Also the quality of the girders seems to be of poor quality. I do not know how it will withstand when the bridge is complete.

Once again the contractor forgot to add cement in the girder........

India never groves until they change their corrupt leader,officers,first people have to change them self ,later everything will come on way....

once the bridge is completed for a month only the contractors and the company that is doing the construction must use it and no one else. they must use vehicles filled with their family members if needed politicians responsible for giving the contract to them. bridges are supposed to be tested with the bullet tankers will this bridge survive a enfeild bullet test or a heavy truck test. what quality this bridge will have. thank God it fell off from the truck. authorities please check the bridge well before declaring it open for the public.

God Will...that is the reaseon the tyre Axel broken so that public can see the quality of the Beam..90% work already finished with this worse quality Beams...how long will this last..!This accident may be to open eyes of the public...Please ask to check all the Grider...before commissioning the project.

Guys, need not to worry about the quality of the concrete beam. Navayuga has to maintain the bridge and road for the 25 years, so they will take care abt the quality. otherwise instead of twenty lakh loss ,they will loose two crore.
Another thing to lookafter the quality NHAI is appointed one consultant name AARVEE assosiates his head is from USA.

Sitting in AC room and typing about quality is easy, concrete beam load capacity is calculated for vertical side and it collapsed in side wise.... so it will get crack. I heard that for each concrete gurder 40 numbers of testing cube will be casted and it will be tesyed in lab after curing it for 28 days. inside stressing will be there.... if any foult is there in concrete slab, it will break while doing stressing. After passing all tests only they will transport. They are not fool or mad to risk their money and name of their company......

Thanks to God for his Mercy. Good thing it is fell off and broken and how God saved the good people who travel through the bridge. In case if it was broken when passengers were traveling, I cannot think the tragedy at time.

We must awake and must put death sentence such culprits what ever it is. These stupid’s are playing with innocents life.

Wake up call for ........

It looks like the mix is mostly sand, if it is a proper mix you should never see a hollow space (as shown in one of the photo). This kind of structure will never last long. I request Daijiworld to take it up with NH authority. They will need to check the entire work now.

This is just start, we are talking about 2021......mangalore only good in page 3 gossiping nothing else. no proper planning .......everywhere kalapey Kama garikey... like our leaders

see photo no-13, how come that much damage. there's something fishy in construction process. NHAI has to investigate soon.

thank god, no passerby vehicles or persons was nearby.

What about the quality of other 95 girders

THANX DAIJI FOR GOOD PICTURES.
THIS GIRDER LIKE OUR KARANATKA GOVT. SEE THE QUALITY OF THE CONCRETE, IT IS REALLY PATHETIC AND THE CONTRACTORS USING THIS FOR THE BRIDGES TO TAKE INNOCENT LIVES.
ALL GOVT OFFICERS AND ALL THE CURRENT POLITICIANS ARE CORRUPT NOT ONLY THAT THEY HAVE LOOTED THE CITIZENS.
COME ON ALL CITIZENS OF COASTAL KARANATAKA, WAKE UP TEACH A LESSON TO THESE CORRUPT AND DISHONEST POLITICIANS, GET TOGETHER AND FIGHT FOR '''KARAVALI STATE'' (KARAVALI RAJYA).

The old netravati bridges are built in British era both railway & roadway , and on those days how would have they built this with less infrastructures and see this 21st century infrastructure shame!!.... we Indians have no any good technology to built this in safe manner ......Though nethravati river water is a salty content these bridges are need to be taken care.

STEVE, MANGALORE, I Agrre with you, but our Capital "Nayak" will say this "NETHRAVATHI BRIDGE" coming under Central govt.

Corruption Prevails Nation Derails
Dear Ministers, Stop the Corruption Build the Nation 65 years of Independent and we still the same....Jai Hoo

Well a girder broke with just the impact of its falling to the ground on account of broken axle. This raises the question as to the quality of the work. Now additional 20 lacs will be spent to replace this girder. How many such mishaps will happen at the cost of tax payers money allowing the corrupt officials involved to pocket the booty. God intervened in this case, brought the quality of work to light.

Quality of Grider used in the bridge only for light vehicle like Rickhsaw, two wheelers am I right?

Best example of inefficency by the Central Govt. The contract was given to Navayug Construction owned by Jagmohan (once a active Congi). Not a single Central Minister visited to the venue, really a shame....Poor quality of work...people perhaps have to pray before crossing the bridge.....

What a shame.......See the quality of the girder.

The quality of concrete is visiible. Definitely this sort of construction won't last long. Contractors should be answerable and made liable for. Who is there to insist?

The incident has brought out the poor quality of the work being done by the contractors and the negligence of the authorities who were supposed to check the quality. Contracting companies will vanish after some years and if there is any accidents public will pay the price.

If bridge girder falls such a low height and breaks so easily then the quality of the work is so poor. We can't expect that bridge for so long time. Most of the money is grabbed. It is better to investigate the quality of work and bring those to justice. It is all public money.

Total failure in maintaining quality... imagine if it would have broken after construction of the bridge... really god saved... praise the lord..

Such a long 33 mtr girder will definitely break if fallen down from trailer. Doubts about quality of work is baseless. Any way God does everything for good. No loss of life. Navyug will get insurance.

DEAR READERS, GET READY FOR THE NEXT NEWS SOON - NETRAVATHI BRIDGE COLLAPSE AND -(GOD SHOW US MERCY) - THIS IS THE QUALITY OF THE PROJECTS IN INDIA

The quality of the girder is sub standard, God alone knows how long the bridge will last.

THANK YOU DAIJJI NICE COVERAGE
