Overview
The Airport Express Line links central New Delhi with Indira Gandhi International Airport. Its underground section uses three tunnelling methods, each chosen to suit the ground and the surface above.
Prof. (Dr.) H. R. Yadav served as Chief Resident Engineer for more than ₹1,480 crore of the underground works, in a prior role.
Engineering challenges
- Matching tunnelling method — TBM, NATM or cut-and-cover — to each reach
- Building underground stations under busy roads and existing services
- Coordinating civil works with high-speed airport-link systems
