Delivering extensive planning and design services for a major expansion to India’s busiest airport – we’re helping to deliver a revitalized Terminal 1, fourth runway, new taxiways and apron, and additional airfield infrastructure at Indira Gandhi International Airport.
The expansion of the Terminal 1 infrastructure at Indira Gandhi International Airport in New Delhi is part of Delhi International Airport Limited’s (DIAL) next major phase of development for India’s capital city airport – Phase 3A – which will increase the capacity of Terminal 1 from 18 to over 35 million passengers per year.
We undertook the concept preparation/preliminary design of key aspects of the large-scale Phase 3A development, including the expansion and extension of Terminal 1 encompassing capacity improvements at Terminal 1D (departures) and a new Terminal 1C (arrivals) to create an integrated Terminal 1 complex.
Our work included delivery of planning and design solutions for an expanded apron to serve Terminal 1, a new multi-level underground car park, taxiways and other improvements to the existing airfield and the new Code F fourth runway, designed to accommodate the largest commercial aircraft, for which we conducted runway length analysis and established the runway declared distances.
We coordinated a multi-disciplinary design team to deliver the wide-ranging scope. Within a short program, we completed extensive optioneering and the selection process for the terminal planning and design, prior to a single preliminary design option being chosen by DIAL.
Additionally, we carried out geotechnical, building and pavement condition surveys within an operational terminal and apron/airfield environment to a challenging timeline, helping to supplement site information. We also assisted the client in the bidding process by providing replies to various technical queries raised and assisted in the technical evaluation of the tenders received from the bidders.
