He was at work at a construction site yesterday when he heard a loud crash a short distance away.
The construction worker, who declined to be named, later heard from colleagues that a man had died after falling from height at the site at Pioneer Turn, off Jalan Ahmad Ibrahim.
Two others were injured in the fall.
The worker, who is in his 20s, said: "I went to the spot where he fell and saw white cloth covering his body."
A signboard at the site indicates that a four- to five-storey light industrial development with a warehouse is being constructed.
The Ministry of Manpower (MOM) said the accident occurred on the worksite of engineering and construction company M+W Singapore.
Its spokesman said that preliminary findings indicate that three workers were working on a platform installed over a stairwell when it collapsed, causing them to fall from the third storey.
MOM has ordered all work at the site to stop, pending investigations.
The Singapore Civil Defence Force was alerted at about 9.40am and sent a fire engine, a Red Rhino, a fire bike and two ambulances.
Paramedics pronounced a Chinese national dead at the scene.
The other victims, a Chinese national in his 40s and a Bangladeshi, were conscious and taken to the National University Hospital.
A worker told reporters the man who died was 28 years old and had been working in Singapore for about a year.
He added: "He had three children - two girls and a boy."
A Chinese national, believed to be a relative of the dead man, was sitting under a tree, with his head bowed.
All he would say was that he was working at the same site yesterday when he found out about the tragedy.
Manpower Minister Tan Chuan-Jin later tweeted about the incident.
He said: "Jumpform collapse at Pioneer Turn. A fatality and two injuries. Condolences. Efforts underway to help injured."
The police said investigations are ongoing.
