Runway Extension I Gusti Ngurah Rai International Airport

Bali hosts millions of international and local travellers every year. The I Gusti Ngurah Rai International Airport (named after a Balinese hero) is Bali’s main airport and the second busiest airport in Indonesia, with around 25 million passengers a year. Currently, aircraft up to the size of a Boeing 747-400, Boeing 747-8, Boeing 777-300ER, Boeing 787-10 and Airbus A350-1000 can use the airport. Our experts were asked by Angkasa Pura (responsible for airport management in Indonesia) to develop a basic design for a runway extension to accommodate even bigger aircraft, like the Airbus A380.

Because the international airport borders the Indian Ocean, the scope of the design covered the basic reclamation work for the runway, which will be 500 metres long. The work included field visits, a geotechnical analysis for stability and a wave modelling analysis (SWAN) to design the dike protection system for the runway. For this analysis, we took into account extreme wave conditions and the influence of typhoons and seismic activity.

The design has been completed and has been presented to the client for further implementation.
