With a chainsaw, he slices through crystal-clear ice blocks like butter.
He then sands them down with an angle grinder. Sparks fly amid a whirring sound as steel meets ice.
The air is -15 deg C.
Walk in without a coat and you'll feel the chill within seconds.
But at times, Mr Jiang Li Ren, 64, works without wearing gloves.
He says: "I'm used to it. When I'm working, my body naturally heats up.
"If I'm cold, it means I'm being lazy."
He is one of 20 master ice sculptors from Harbin, China, who flew in to create ice sculptures for the 2 Degree Ice Art Exhibition, which has been billed the largest of its kind in Singapore so far.
The show will open on Wednesday at the open ground next to Marina Bay Sands hotel, and over 100,000 visitors are expected.
Over 450 tonnes of ice - both clear and coloured - were used to complete the entire exhibition.
They came from factories here and in Malaysia in 30 trucks.
And it took 60 days to complete the entire set-up.
Visitors can expect 28 ice sculptures, some of which are modelled after iconic landmarks like Paris' Eiffel Tower, the pyramids of Egypt and the Statue of Liberty in the US.
The largest, London's Big Ben clocktower, stands at 6m tall. It is 10m long and 4m wide.
Local icons like the Sultan Mosque, Raffles Hotel and the Merlion have also been rendered in ice for the exhibition The mosque sculpture's embedded LED lights glow red, blue and green.
