Please describe the project specifications
Yogyakarta's Special Region in Indonesia is now served by the new Yogyakarta International Airport (NYIA) at Kulon Progo Regency. Our contract for the airport development covered the design and supply of an ETFE roof as part of an ETFE and PC roof. The roof provides 18,900 square meters of weather coverage to the exterior drop-off area. The airport is operated by Angkasa Pura, and operates 24 hours a day, servicing approximately 54 flights daily.
The ETFE roof creates an exciting and memorable space and the airport terminal. There is 14,314 square meters of ETFE, comprised of 84 double-layer pneumatic cushions. The bottom layer of the cushions features clear ETFE, while the top layer has a 63% printed silver frit pattern on the ETFE. The ETFE pillows are grouped into 21 clusters of 4 cushions. The roof design resembles a native Indonesian flower design, Kawung.
What is unique or complex about the project?
The installation of the ETFE was complex. This was primarily due to the tight constraints of the program. We were working closely with other trades during installation, including trailing the steel and cladding installers. Extensive coordination was required throughout the installation to ensure that we could meet the scheduled deadlines. These deadlines were set around the opening plans for the entire airport!
The client was super happy with the project and the end results are extremely captivating. There were no quality issues from inspections and our delivery was on time and on budget. The ETFE cushion canopy lights up with bright colours due to an LED lighting system that is incorporated on the underside of the cushions.
