"One of the workers, identified as Rijaul Abdul Goni, 40, died on the spot. Another identified as Shanaullah, 37, was injured and has been sent to the Kuala Lumpur Hospital.
"The third person identified as Rozlu Karim escaped injury," the spokesman said.
The workers were assembling a steel cage, when the ties that held the steel bars snapped, causing it to collapse on the workers. When asked about the weight of a single steel bar by local media, the spokesman said each bar weighs about 70kg.
Investigations have commenced to determine the cause of the accident. Work has been suspended at the V4 Semantan Portal interface site until further notice.
