Grimshaw and Heatherwick Studio are understood to be among the practices in the final round of the contest to design a huge new terminal at Changi Airport in Singapore
According to sources, the practices are on a three-strong shortlist in the competition to design Changi’s ambitious new Terminal 5 development.
It is rumoured Heatherwick Studio has teamed up with KPF and engineering stars AKT II on its submission, while Grimshaw is collaborating with Singapore’s DP Architects. There is speculation the third entry comes from SOM with Moshe Safdie, although the official shortlist has yet to be announced.
It is understood a bid by Rogers Stirk Harbour + Partner with local outfit SAA Architects failed to make the cut for the final round.
Planned to handle 50 million passengers a year in its initial phase, the 1,080ha project will expand Changi Airport’s total capacity to 135 million when it completes in the late 2020s.
The scheme is part of an £890 million expansion programme known as Changi East, which will deliver a three-runway system at the busy airport built on reclaimed land east of the city state.
The new Terminal 5 will be connected to the existing Terminal 1, 2 and 3 buildings and with Singapore’s mass rapid transit network.
Work on Changi’s £726 million Terminal 4 – which features a glazed atrium containing the world’s highest indoor waterfall – started two years ago and is due to complete in 2018.
Designed by Moshe Safdie and Benoy, the 134,000m² scheme, known as the Jewel Changi Airport (pictured top), will feature a hotel and retail developments with five levels of underground parking.
Other firms vying at earlier stages for the prize job include RSHP, which won a separate contest to expand Taoyuan International Airport in Taiwan a year ago.
Earlier this year, Grimshaw won a contest to mastermind the £16 billion enlargement of Heathrow Airport which is part of recently approved plans for a controversial third runway.
The practice was also chosen for a massive expansion of Peru’s main international airport in Lima two years ago.
Changi Airport Group did not reply to a request for comment. At longlisting stage a spokesman declined to confirm the teams but said: ‘We have started the process of selecting our design partners for Terminal 5, and will be working towards a shortlist of firms to have further discussions with in the coming months.’
