The workers, one of whom suffered a broken arm, were thrown to the ground when the structure they were standing on gave way at 4pm on Saturday.
Ambulances rushed the injured workers to the Sarawak General Hospital where most of them were given outpatient treatment for cuts and bruises on their bodies.
An eyewitness said that the structure collapsed as the workers were pouring mixed concrete on part of the first floor of the building.
The cause of the incident is being investigated.
Some 25 workers, most of them foreigners and aged between 25 and 35, were working on the project when the incident occurred.
