From Concrete to Compute

How SN Subrahmanyan Is Shaping L&T's AI Future For more than eight decades, Larsen & Toubro (L&T) has been synonymous with India's physical infrastructure, delivering metro systems, airports, power plants and some of the country's most complex engineering projects. Under L&T Chairman SN Subrahmanyan, however, the company's definition of infrastructure is expanding. Increasingly, it includes artificial intelligence, cloud computing, data centres and sovereign digital infrastructure the building blocks of India's next phase of economic growth. That shift came into sharp focus at the India AI Impact Summit 2026, where SN Subrahmanyan joined NVIDIA founder Jensen Huang to unveil a strategic collaboration aimed at accelerating AI infrastructure in India. The announcement reflected more than a technology partnership; it signalled L&T's ambition to evolve from a builder of physical assets into an enabler of the country's AI-powered future. An Engineer's Perspective on AI Unlike many business leaders who entered the AI conversation as the technology gained mainstream attention, SN Subrahmanyan approaches it through the lens of an engineer. A civil engineering graduate, he joined L&T in 1984 as a project planning engineer and spent four decades leading some of the company's largest infrastructure businesses across India and the Middle East, including projects such as the Riyadh Metro, Doha Metro and Salalah Airport. After serving as Chief Executive Officer and Managing Director from 2017, he became Chairman and Managing Director in 2023. That experience continues to shape his leadership philosophy. Rather than viewing AI as a standalone technology trend, Subrahmanyan sees it as an extension of engineering one that can improve planning, design, execution and operations at scale. During L&T's FY2024 Annual General Meeting, he described generative AI as a "game changer" and outlined how the company was embedding it across the project lifecycle to improve productivity and decision-making. Why L&T Is Investing in AI Infrastructure For L&T Chairman SN Subrahmanyan, AI is not only about adopting intelligent software; it is about building the infrastructure that makes large-scale AI deployment possible. Through its collaboration with NVIDIA, L&T plans to develop one of India's largest proposed AI infrastructure ecosystems. The first phase includes expanding GPU capacity at its Chennai campus to approximately 30 megawatts while developing a 40-megawatt AI-ready data centre in Mumbai. The infrastructure is intended to support hyperscalers, enterprises, research institutions and government organisations building AI applications across manufacturing, healthcare, financial services, energy and the public sector. The initiative aligns with Lakshya 2031, L&T's long-term growth strategy, which identifies digital infrastructure, cloud services and artificial intelligence as key growth engines. Alongside expanding AI-ready data centres, the company has strengthened its technology portfolio through investments such as its strategic stake in E2E Networks while leveraging businesses including LTIMindtree and L&T Technology Services to create an integrated digital ecosystem. As governments worldwide race to build sovereign AI capabilities, companies that control compute infrastructure rather than just software are expected to occupy a strategic position in the AI value chain. L&T's investment signals that India's AI ambitions extend beyond developing models to building the physical and digital infrastructure required to run them at scale. Building India's AI Backbone Subrahmanyan has consistently argued that AI requires more than algorithms it requires infrastructure. As enterprises move from experimentation to production-scale AI, access to secure compute, cloud platforms and data infrastructure is becoming as critical as traditional industrial assets. This philosophy reflects a broader global trend. Countries are increasingly investing in sovereign AI capabilities to reduce dependence on overseas infrastructure and strengthen digital resilience. L&T's strategy positions the company to participate in this transformation by combining its expertise in large-scale infrastructure delivery with emerging AI technologies. For an engineering company known for constructing roads, ports and industrial facilities, building digital infrastructure is a natural evolution rather than a departure from its core strengths. Leadership Beyond Technology Despite leading one of India's most significant AI infrastructure initiatives, SN Subrahmanyan has consistently maintained that technology alone cannot drive transformation. In L&T's FY2025 Annual Report, he emphasised that while AI is accelerating innovation, long-term value will continue to depend on human judgment, responsible deployment and disciplined execution. That balanced perspective reflects the leadership approach that has defined his career. Rather than pursuing technology for its own sake, he has focused on integrating new capabilities into L&T's long-standing engineering excellence and execution discipline. From Concrete to Compute As industries become increasingly digital, infrastructure itself is being redefined. The assets powering future economies will include not only highways, airports and power plants, but also AI factories, cloud platforms, GPU clusters and data centres. Under SN Subrahmanyan's leadership, L&T is positioning itself at the intersection of these two worlds. The company's strategy is not about replacing concrete with compute; it is about recognising that tomorrow's infrastructure will combine both. If that vision succeeds, L&T Chairman SN Subrahmanyan may be remembered not only for leading one of India's largest engineering companies but also for helping build the digital foundations of the country's AI economy.

Why is Mamata Seeing Ghost of Bangladesh?

Updated: Oct 21, 2024

Why is Mamata Seeing Ghost of Bangladesh?

Mamata is seeing a ghost of Bangladesh behind the massive outrage and waves of protest over rape and murder of the trainee doctor. And the reasons are many.

It’s been over a fortnight. Yet with each passing day the voice of protest is getting louder and stronger. From the streets of Kolkata it’s pouring into roads of hinterland. The cry for justice for a rape victim has consolidated into a wail of demands to set a lot of wrongdoings right. Here in lies the fear and trepidation. Wasn’t the issue that brought the youth of Bangladesh out on the thoroughfares a simple, innocent one of quota reform?

The chief minister of Bengal, known for understanding the pulse of people better than many, was quick to read the signages floating in the political horizon.

The most obvious reason for her to be tensed is that both the regime change in Bangladesh and the mass protest in Bengal, were student-driven to begin with. The two incidents---end of 15 year old Sheikh Hasina government and turbulence in West Bengal, over the heinous crime, falling back to back, the first on August 5th and the latter from August 9th onwards, give natural scope for comparisons. More so, because in both the cases the movement strayed beyond an affected constituency to include aggrieved people at large, cutting across socio-economic demography. If the quota reform protest started by students in Bangladesh became a mass uprising against an autocratic regime, the campaign demanding justice for the rape victim and overall safety and security of women in Mamata Banerjee’s Bengal soon snowballed into a movement of no-confidence against the government. Slogans--”Mamata must resign” also got floated in social media much in line with the call for ouster of Sheikh Hasina. In fact “Resignation of Hasina” became the single point agenda into which all other fringe demands coalesced.

Incidentally, even before people started drawing parallels, that there could be a thread of commonality in the way the upheaval in Bangladesh and Bengal played out, Mamata was quick to point out that the Opposition were trying to pull off a Bangladesh by politicizing the tragic incident: “A coordinated approach has been executed by the BJP and the CPIM with support from the Centre to defame Bengal and exploit the situation....They want to make a Bangladesh here. They are taking cues from student unrest in Bangladesh and are attempting to capture similarly. I have no longing for the chair. I came here to serve people.”

Not only Mamata, her political lieutenants are consistently equating the turmoil in Bengal with the mayhem in Bangladesh. Cabinet minister for North Bengal development Udayan Guha threatened to take stern action against those, who would be trying to exploit the situation by emulating a Bangladesh like movement. “ Even after the hospital was vandalised, the police did not open fire on anyone. The police will not allow a Bangladesh type situation. We will not allow Bengal to turn into Bangladesh, Guha thundered.

Is the government’s fear unfounded?

Apart from the similarities on ground zero, as to how and where the future course of events are heading to, there are ample reasons for Bengal to mull on-- as to what led to a Bangladesh like boiling point. To begin with, it’ll be appropriate to talk of Bangladesh and the prevailing situation, that made the students’ protest become big in magnitude. The students were out on the streets because of a high reservation in public jobs. Unemployment and stagnant job market in private sector coupled with a high rate of inflation drove the educated youth to rebel against the government.

But soon the students found enormous number of sympathisers, who were equally at the receiving end. According to Bangladesh citizens, the last two terms of the Sheikh Hasina government were a mockery of democracy. Even elections would be compromised. As Hasina grew from strength to strength, she politicized institutions. The rank and file of police owed allegiance to the ruling dispensation. Extortion, harrassment and raids by police and people in power became rampant. An atmosphere of fear and repression reigned and people got restless to overthrow the government.

Politicization of institutions has been happening in Mamata government too. Allegations are quite strong that police in Bengal functions at the beck and call of political bosses. The lapses and alleged loopholes on the part of police in handling the rape and murder of the young doctor have yet again revealed a sense of confused or misplaced loyalty.

But above everything else both Hasina and Mamata governments allegedly seem to have twined in accepting corruption as a way of life. In Bangladesh jobs of primary and secondary teachers got sold at premium, Rs 10-12 lakh in the Hasina regime. Even police had to pay up for prized postings and transfers. In Bengal busting of the teacher’s recruitment scam has revealed how unsuccessful and ineligible candidates got government jobs in schools in exchange of bribes.

Similarities are multiple and inescapable. Mamata has good reasons to be apprehensive. It’s not only she, who can see and connect the dots. People, out on the streets, clamoring for justice, can see a providential pattern somewhere in the unfolding of future events in these two places-- Bangladesh and Bengal. True, they share more than 2,217 odd km of border. They share the same umbilical cord, other than language, culture, ethos, icons. Even emotions are the same. So she cannot take any risk.
