Mumbai’s Crumbling Infrastructure: Knee-Jerk Solutions Leave Mumbai’s Lifeline without a Spine- Part 2
It is unusual to demolish bridges, which are lifelines of a city, without arranging an alternate travel path. New replacement bridges for the Bay Bridge between Oakland and San Francisco, California, or the Tappan Zee bridge in New York or even the Vashi bridge in Mumbai were commissioned before the old bridge was demolished. 
 
It is astounding to any structural engineer why a steel bridge, which is relatively much simpler to retrofit, could not have been strengthened adequately for it to last until a new bridge was built and traffic shifted to it before commencing its demolition.
 
It is also a sad statement on another of Mumbai’s institutions, the Heritage Committee of Mumbai, which did not insist on this. Delisle bridge was a steel bridge fabricated in England and shipped piece by piece to Mumbai in 1918. And it is a damning statement on the apathy of Mumbai’s structural engineers that they did not intervene and imagine an innovative retrofit for the bridge.
 
 
We need to reflect if as a society we have even a modicum of a scientific temperament left in us. Following the partial collapse of the floor slab system of the foot overbridge (FOB) at the CSMT railway station, the municipal corporation overnight dismantled the main girders of the bridge which were in perfectly good condition, behaving like bumbling police in detective films who mindlessly destroy or contaminate all evidence at the scene of the crime.
 
 
So we have an inquiry based on an absent bridge and absent files (the drawings file of the bridge has gone missing). The hapless auditor of the bridge was a company started by a professor of one of the oldest government engineering colleges in Mumbai. So at one end we have implementation of a non-peer-reviewed decision to demolish the Delisle bridge, which has caused loss of billions of rupees in lost time due to perennial traffic snarls at Parel and at the other end a dangerous safety affirmation of a seriously compromised FOB at CSMT.
 
 
We need to have more systems and processes in place. Atul Gawande, in his book “Checklist” sings paeans to the detailed system of checklists prevalent in the construction industry. If only he knew the reality in India. It serves no one, least of all the financial capital of India to use Indian Institute of Technology (IIT) or some favoured consultant(s) as a fig leaf to rubber stamp and whitewash systemic problems in infrastructure.
 
Crumbling infrastructure is a global problem but nowhere is it treated with such nonchalance as in India. It is not necessary for the municipal corporation or the railways to get into a defensive mode after each failure. And it is self-defeating to see every failure as an occasion to guillotine some municipal engineer or use a structural consultant as scapegoat. 
 
 
It would serve the municipal corporation better if it could get into a proper enquiry mode to understand causes of failure and then create a road map for avoiding similar situations in the future. 
 
Conversely, every time we have a bridge deemed unfit for use by a consultant, we need to have a committee review this and see the cost-benefit ratio to carry out repairs to extend its life until a replacement bridge is in place rather than simply demolishing it without a Plan B in place. The culture of cronyism in the selection of consultants and contractors needs to be done away with, if we have the intention of improving the infrastructure of the city.
 
And pray, what would it take for the railways to shake the dust off its own maintenance manuals and regain its lost glory of excellence in engineering?

Seems the intention of the powers concerned is to turn Mumbai infrastructure into an FMCG company where products are bought every few yrs!

Mumbai’s Crumbling Infrastructure: Are We Burning Our Bridges before Crossing Them? -Part 1
The most memorable character for me in ‘Alice's Adventures in Wonderland’ was the whimsical ruler, the Queen of Hearts. Her much-loved phrase, which she would repeat ad nauseam was "Off with his head!" or "Off with their heads!"
  
I was reminded of her when I read in a news on 12 May 2019 that, based on a report from Indian Institute of Technology (IIT) Bombay, the Western Railway had ordered another bridge to be demolished, this time a foot overbridge (FOB) at the busy Dadar station. 
 
The alacrity with which this decision has been taken demonstrates extreme nervousness on the part of the railways administration after the partial collapse of the FOB near Chhatrapati Shivaji Maharaj Terminus (CSMT) on 14 March 2019 and its reluctance to take a more considered line of action, including a peer review.
 
I wonder if the possible fallout of this decree to demolish the Dadar FOB has been adequately examined, because while the memory of the CST FOB collapse is still fresh in the minds of the state apparatus, it appears that the stampede of 29 September 2017 in which 23 people lost their lives has vanished from our collective memory. 
 
The demolition of this wide overbridge at Dadar has the potential to cause chaos in the event of two trains arriving at a platform in quick succession as the other parallel bridges are challenged by bottlenecks caused by narrow landings. 
 
 
I doubt if a disaster scenario simulation and testing had been carried out before such a far-reaching decision was taken. And there is certainly no concern for the inconvenience likely to be suffered by commuters, harried as they already are by the simultaneous construction of the metro line, road repairs and road excavations to lay numerous pipes and cables. 
 
The city has not yet recovered from IIT Bombay’s earlier edict to demolish the Delisle bridge and continues to reel from the loss of millions of rupees due to perennial traffic snarls at Parel, arguably Mumbai’s new financial hub. 
 
It would be fair to ask what exactly constitutes an 'IIT' report, for it to be taken as the Holy Bible by the administration. 
 
For the government, IIT is a magic wand-wielding institute, a one-stop solution for all the government’s woes when it does not know what to do with a dilapidated building in the monsoon or is facing a public interest litigation (PIL) on account of its stock of poorly maintained infrastructure—bridges, hospitals, schools, colleges or when it wants to draft the building codes for the country (a look at the code committees of the Bureau of Indian Standards would be illuminating) or for vetting new construction. (Many cities in the country have made being a faculty member of an IIT a very lucrative affair by mandating that all buildings within their jurisdiction exceeding the stipulated height or size must necessarily be vetted by an IIT or equivalent).
 
IITs can, at times, churn out reports with astonishing speed, much to the delight of the government. Imagine, a faculty member of IIT Bombay can be tasked with the study and submission of the status report of 447 bridges across Mumbai within six months. 
 
Unsurprisingly, we have two bridges in the commercial capital of the second most populous country demolished on the directions of an IIT Bombay report. When in doubt, as the queen says, “Off with his head!”
 
Having been a visiting professor at one of the older IITs for three years and worked for over two decades with numerous IIT professors, I have seen first-hand that IIT reports are not that of the institute but of an individual faculty member. 
 
It is not inconceivable to get completely opposing reports for a structure from different faculty members of the same IIT. That, an IIT professor once proudly said to me, speaks well of the independent and fearless mindset of the IIT professor.
 
While that may be true, in some areas, especially in matters of physics and mechanics, one would wish that an addition of two plus two would unfailingly yield the same result of four, especially when the stakes are high.
  
There is nothing 'institutional' about reports from IITs, unlike the institutional mechanisms that are followed in larger engineering organisations- government or private. In such organisations, a well-defined system exists in terms of supervision, oversight and signoff at many levels. There is room for discussion and debate and the final report that is released has usually passed multiple reviews which the organisation has to take full ownership of.  
 
Not so in an IIT project. The work is done by the individual faculty member and is seldom subject to review (unless expressly stated by the client) by a second faculty member. Hence, the report of an IIT is oftentimes quite simply the opinion of a single IIT professor.
 
More importantly, a professional organisation (public or private) is legally liable for the design or report. But IITs do not feel the need to stand up to public scrutiny.  
 
Here is what is put up by IIT Bhubaneshwar on its website. “The Institute undertakes to carry out the project as conscientiously as conditions allow, but accepts no economic responsibility should the work not lead to expected results. The Institute accepts the project on condition that the client renounces all right to claim damages for losses sustained directly or indirectly in consequence of the work done by the Institute.” 
 
Such a disclaimer should be sufficient for any client to scurry for cover. And, yet, for project after project, the government will turn exclusively to the IITs for advice on new projects, disaster management, health of public infrastructure and much else. 
 
Whatever happened to the Indian Railways cadre of engineers, the Indian Railways Service of Engineers (IRSE), considered to be one of the oldest and most elite of all Indian engineering cadres that  manages the department of civil engineering in the Indian Railways?
 
It is a shame that the Indian Railways, which had one of the most comprehensive systems for inspection and maintenance (the granular “Indian Railways Way and Works Manual” was first published in 1967 and has seen numerous upgrades along the way), has capitulated to the downward spiral in our institutions and has now subcontracted its duties of inspection and audit to small time consultants or  one-man armies of the IITs. 
 
What does the Indian Railways have  to say for itself when one of its own bridges (Dadar FOB) constructed in 1993 and which has barely reached midlife, is now deemed to be so  heavily corroded as to be unfit to carry intended  loads? 
 
(This is first part of a two part series.)

Completely agree with Dr. Alpa Sheth. I have very experienced a report issued by IIT professors who were unwilling to support or discuss the rationale of their recommendations for repairs.

Incidentally IIT is my alma mater

One of the main reasons I'm hesitant to move back to Bombay. Crumbling infra coupled with insane real estate prices/rentals. And NO long-term vision for the city. At some point, the "spirit" will just wane and give way to frustration and and hoplessness. BMC, MMRDA, et al, need to get their act together before it's too late. Just look at Bangalore --an unmitigated mess.

PS: I have rather fond memories of Dadar station, one of the liveliest places and full of positive energy, but it's scary AF. After the recent footbridge tragedies, I don't want to step anywhere close to these places. Sadly.

Hindi speaking states Bihar, MP, Rajasthan, UP (BIMARU) are most backward. People from these states migrate to non-Hindi speaking cities in millions and put pressure on local infrastructure.

New system of measurement units now operational
The new System of Units (SI) to measure weight, temperature, amount of substance, and current came into operation in India from Monday on the occasion of the World Metrology Day, an official release said.
 
The resolution to redefine four of the seven base units - the kilogram (SI unit of weight), Kelvin (SI unit of temperature), mole (SI unit of amount of substance), and ampere (SI unit of current) - was adopted at the 26th General Conference on Weights & Measures (GCWM), which is comprised of 60 member countries, in November 2018.
 
"This decision has now enabled scientists and researchers to base the SI units entirely on fundamental properties of nature, which will ensure their ongoing refinement and improvement for years to come," the Science and Technology Ministry Ministry said in a release.
 
"The fundamental constants are invariants of time and space and successfully replaced the artifact-based units, and aptly opened up the new era for quantum world by linking all seven base units to fundamental constants/quantum standards."
 
The existing definition of the kg is over 130 years old. The new SI system, which is defined in terms of Planck's constant, would be stable in the long term and practically realisable.
 
The new SI System will be helpful in bringing in accuracy while dealing with international trade, biotechnology, high-tech manufacturing and human health and safety.
 
The new definition of kg involves accurate weighing machines called 'Kibble balance', which uses Planck's Constant to measure the mass of an object using a precisely measured electromagnetic force.
