A joint venture between Woh Hup and Obayashi Singapore has been appointed main construction contractor for the upcoming retail and leisure attraction, as well as for the expansion of Terminal 1.

SINGAPORE: Changi Airport Group (CAG) announced on Tuesday (Oct 28) that a S$1.57 billion contract has been awarded to a joint venture formed between Woh Hup (Private) Limited and Obayashi Singapore Private Limited for the construction of Project Jewel and expansion works at Terminal 1 (T1).

The construction joint venture will be working with the Jewel Changi Airport Trustee (JCAT) and CAG on proposed construction work, including the redevelopment of the 3.5 hectare open-air carpark site fronting T1, CAG said in a media release.

Project Jewel, a mixed-used development, will feature a dome-shaped facade made of glass and steel. The 1.4 million square feet complex will also have a 40-metre waterfall and a large-scale indoor garden, in addition to leisure attractions, retail stores, and hotel facilities. New pedestrian bridges linking Project Jewel to Terminals 2 and 3 will be built as well.

T1 will be expanded to include a larger Arrival Hall and more spacious baggage claim areas following the redevelopment of the open-air car park. A five-storey basement car park and additional taxi bays will also be developed, while the terminal's Departure drop-off bay and Arrival pick-up point for private cars will be expanded to cope with increasing passenger traffic.

Construction work is expected to begin by the end of this year, with Project Jewel and the majority of T1 expansion works targeted to be completed by the end of 2018.
