Engineering Firms Target India's ₹91,000-Crore Airport Expansion

India's civil aviation sector is undergoing a massive infrastructure overhaul, backed by a combined ₹91,000-crore investment from public and private entities. This spending is set to create a significant pipeline of projects for the country's leading engineering and construction firms. The investment includes ₹25,000 crore from the Airports Authority of India (AAI) for projects between 2025 and 2029, ₹30,000 crore for upgrades at existing Public-Private Partnership (PPP) airports, and ₹36,000 crore for new greenfield airports.

This capital expenditure wave directly benefits airport operators and the Engineering, Procurement, and Construction (EPC) companies responsible for building terminals, runways, and air navigation infrastructure. As passenger traffic grows, firms with established track records in large-scale projects are positioned to capture a substantial share of the upcoming contracts. The development impacts key stakeholders, including construction firms gaining large contracts, airport operators anticipating higher revenues, and passengers who will see improved facilities.

GMR Airports: A Direct Play on Passenger Growth

As one of India's largest private airport operators, GMR Airports is directly exposed to the country's rising passenger volumes. According to its Q3 FY26 earnings release, airports managed by the group handled 31.9 million passengers, a 2.5% year-on-year increase, accounting for approximately 27% of India's total traffic. The company's gross income for the quarter rose to ₹40.8 billion, up 49% YoY, though net profit was slightly lower at ₹1.7 billion.

GMR is also expanding its physical footprint. The Bhogapuram airport project in Andhra Pradesh is reportedly 95.8% complete and is expected to become operational by the second quarter of FY27. Despite its strong market position, the company's financials reflect the high-debt nature of airport development. More details on the company's performance are available via GMR Airports Investor Relations.

Larsen & Toubro: The EPC Giant

Larsen & Toubro (L&T) stands as a primary beneficiary of the infrastructure boom due to its extensive EPC capabilities. The company has a proven track record, having executed construction for major airports like Navi Mumbai, Bhogapuram, Delhi, and Bengaluru. According to its Q3 FY26 earnings release, L&T's total order book stood at a formidable ₹7.33 trillion as of December 2025.

The company reported revenue of ₹71,400 crore for the quarter, a 10% YoY increase. However, its reported net profit was impacted by a one-time provision related to India's new labour codes. L&T's project pipeline remains robust, with international projects, particularly in the Middle East, accounting for nearly half of its order book.

NCC and Ahluwalia Contracts: Strategic Niche Players

Other significant players include NCC and Ahluwalia Contracts (India). NCC, which undertakes turnkey EPC and Build, Operate, and Transfer (BOT) projects, held an order book of ₹79,571 crore as of December 31, 2025. The company has delivered projects at airports in Agartala, Patna, and Lucknow. Its recent performance was affected by payment delays in non-aviation government projects, but management has indicated that payments are recovering, which should improve project execution.

Ahluwalia Contracts specializes in high-value terminal redevelopment. The company's Q3 FY26 net profit came in at around ₹54 crore. It is currently executing terminal projects at Varanasi and has been named the lowest bidder for the proposed Kota greenfield airport. The company's unexecuted order book stands at ₹18,679 crore, with infrastructure work forming nearly 20% of the total.

Context and Industry Trajectory

This infrastructure push builds on precedents set over the last two decades. The privatization of Delhi and Mumbai airports in 2006 established a successful PPP model that resulted in significant capacity expansion and modernization. That framework now underpins the current ₹91,000-crore investment wave. Furthermore, the launch of the UDAAN Regional Connectivity Scheme in 2016 spurred development at underserved airports, creating the foundation for the current focus on Tier-2 and Tier-3 greenfield projects.

However, the sector faces headwinds. According to the National Green Tribunal (NGT), pollution control restrictions in areas like Delhi-NCR can force temporary construction halts, impacting project timelines. Financial analysts also point to margin pressures on contractors stemming from delayed government payments and high debt levels, representing a key financial risk despite massive order inflows.

What Comes Next

Several key milestones are anticipated in the near future. The amalgamation of NCC Infrastructure Holdings with NCC Ltd was confirmed by the NCLT and completed by February 28, 2026. Looking ahead, Phase 1 of the GMR-led Bhogapuram International Airport is expected to be completed by June 2026. Construction on the Kota Greenfield Airport, for which Ahluwalia Contracts is the L1 bidder, is expected to commence in the second half of 2026.

Why This Matters

This sustained, large-scale investment signals a multi-year growth cycle for India's aviation infrastructure. For engineering and construction firms, it provides revenue visibility through a deep pipeline of high-value EPC contracts. For the aviation industry, it is a critical step toward building capacity to meet projected passenger demand, which is essential for India's economic growth and global connectivity.
