The $1.57bn contract to build the ambitious Project Jewel at Singapore's Changi Airport has been awarded to a joint venture of Woh Hup and Obayashi Singapore.
The Jewel Changi Airport Trustee and the Changi Airport Group (CAG) stated that they expect construction to start by the end of the year. The two companies will also handle the expansion of Terminal 1 (T1).
As a part of the project, the joint venture will be working with JCAT and CAG on the proposed construction works, which will include the redevelopment of the 3.5 hectare open-air car park site in front of T1.
Project Jewel will see the construction of a dome-shaped facade made of glass and steel, which will measure about 1.4 million feet squared. It will also feature a 40m-tall waterfall and an indoor garden.
The airport also claims that the project will strengthen the airport's existing services and enhance passenger experience. There will be early check-in offerings, facilities dedicated to the fly-cruise and fly-coach passenger segment, as well as training facilities and communal event spaces for the 40,000-strong airport community.
There will also be a larger arrival hall and baggage claim area. In addition, the terminal's departure drop-off bay and arrival pick-up point for private cars will be expanded to handle the increasing number of passengers.
Connectivity will also be improved with the help of new pedestrian bridges, which would link Project Jewel to Terminals 2 and 3.
Jewel Changi Airport chief executive officer Philip Yim said: "We thank the companies that had participated in the tender exercise.
"We received very competitive proposals and the past few months have been intensive, as we went through a very rigorous process with several rounds of evaluation together with the tenderers."
Completion is targeted for the end of 2018.
