SINGAPORE, Piling, excavation and structural works for the five basement levels and five above-ground levels of Jewel Changi Airport have been completed, with the S$1.7 billion mixed-use development on track to opening in 2019.

Set to host a range of shopping and dining options, Changi Airport Group (CAG) told Channel NewsAsia that to date, 65 per cent of Jewel's overall construction has been done.

Currently, other major works taking place include the building of link bridges to connect Jewel with Terminals 2 and 3, as well as the installation of Jewel's glass and steel facade.

Starting from the first quarter of next year, play attractions like the Sky Nets, Discovery Slides and Canopy Mazes will be installed.

Trees, ferns and other plants that will make up the 22,000 square metre Forest Valley will start being moved into the complex in the second quarter of 2018, when the building's facade and air-conditioning system are fully fitted.

"(Jewel Changi Airport) will change a lot in terms of passenger experience, it will draw some of the local crowds as well, said Assistant Professor Terence Fan, a transport analyst at the Singapore Management University.

That is going to be a major shift in itself because typically we used to see airports as solely related to travel, but with Jewel being such a retail destination in itself, we can certainly even see locals going there not just for aviation-related activities."
