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.

Lateral upgrade to ailing annihilation

Being the first person from the private sector to be appointed as chairperson of Securities and Exchange Board of India (SEBI) as part of the government’s lateral initiative, Madhabi Puri Buch also holds the honour of being the first woman to hold the top post as capital market regulator.

But the laurels that the former private sector banker enjoyed in her earlier stint with ICICI Bank, was marred with allegations that she and her husband were having a stake in offshore entities, which were used to artificially inflate shares of Adani group companies.

Terming the allegation as `character assassination, Buch clarified that all disclosures have already been furnished and the fund in question did not invest in any securities involving the Adani group.

When it rains, it pours. This allegation was subsequently followed by Congress Party allegation that Buch had received salary and post-retirement benefits from ICICI Bank after she quit the private sector bank.

In its clarification to the stock exchanges, ICICI Bank asserted that the payments made to Buch were purely retirement benefits after her exit from the bank and they were neither salary nor employee stock options.

Prior to these allegations, Buch tenure at SEBI was all about bringing in quick reforms on operational issues by changing the format of consultation paper to bring in larger responses digitally. Being data savvy, the rationale of her decisions were democratic based on big data analysis derived from the responses received to the consultation papers.

Further she bifurcated the duties of the SEBI staff between operations and enforcement, which were done by the same persons earlier. Having worked for the private sector in the capital market domain space, Buch had a better understanding of the subject compared to officers from the administrative service in the past that reflected even in her orders as a whole-time director at SEBI before becoming the chairperson. As a whole time director at SEBI, her orders on adjudication issues were more directional to the capital market space, according to experts in the compliance space. She was also quick to revamp the old provisions of the 90s at SEBI.

Being tech and data savvy, Buch enhanced regulatory surveillance and detection of market manipulation, insider trading and fraud while also emphasizing on strengthening corporate governance by introducing stricter rules for independent directors and enhancing disclosures for related-party transactions.

To put in perspective, the annual report of the capital market regulator in the just concluded financial year revealed that the number of investigations related to insider trading jumped to 175 in 2023-24 from 85 in the preceding year while probes related to front running jumped over three times to 83 from 24 in the preceding year.

Transparency in mutual funds by implementing measures to protect retail investors along with tightening norms for initial public offers, particularly in the SME platforms were some of her other positive initiatives including confirmation of denial of any market rumours within 24 hours for the top 100 listed companies which will be extended to top 250 companies from December 1. However increased transparency and compliance with tightening regulations led to increased operational costs for the market participants and hence faced resistance from certain quarters. Born in 1966, Buch completed her primary education in Mumbai and graduated with specialization in Mathematics from Delhi and later obtained a management degree from Indian Institute of Management, Ahmedabad. In between, she got engaged to Dhawal Buch, a director at a consumer goods multinational at the age of eighteen and got married at the age of 21.

Besides ICICI Bank, Buch also worked as a lecturer at a college in England, worked at Greater Pacific Capital in Singapore and ICICI Securities as its CEO. She also worked as executive director on several private sector companies and as a consultant for New Development Bank (Brics Bank).

What now remains to be seen, is whether Buch, who survived the 26/11 terror attack when she along with her husband, was attending a meeting at Taj, be able to overcome the current ordeal. Keeping fingers crossed for the times to come.
