At about 0330 this morning, a section of the viaduct structure between two piers collapsed at the worksite where the new road viaduct from TPE (Changi) to PIE (Westbound) is being constructed.

The contractor, Or Kim Peow Contractors Pte Ltd was carrying out works to cast the decking for the new viaduct adjacent to the slip road from Upper Changi Road East to PIE (Changi). For the safety of motorists, the slip road was closed to traffic while the works were being carried out.  The collapsed structure spilt onto the slip road, making the road impassable.

11 workers were working on top of the structure during the accident. One worker was killed and the other ten injured. The injured workers were immediately sent to Changi General Hospital.

The deceased worker is from the People’s Republic of China, while among the injured, 6 are from Bangladesh, 3 from the People’s Republic of China and 1 from India.

LTA engineers, contractors and personnel are on site working with SCDF and Police to manage the situation. LTA has also begun safety investigations into the cause of the accident in order to see if there are any lapses or gaps we would need to address urgently.  In this regard, LTA has among others directed the professional engineers (qualified persons in design & supervision) who were responsible for the project to carry out detailed investigations into the design and construction quality of the affected structure.  LTA is also working with the Ministry of Manpower (MOM) on their investigations.

Preliminary investigations indicate that the corbels supporting the pre-cast beams had given way. As a precautionary measure, LTA is checking all other work sites.

Works at all LTA road and rail construction sites will observe a safety timeout this morning.

We are saddened by the accident and will do whatever we can to assist the families during this difficult time.  LTA officers have been assigned to help the injured workers and the families.
