Seventeen other people, mostly construction workers who were sleeping at the building site when disaster struck, remained missing, Sajili said.
The cause of the collapse is not known.
Officials said up to 70 people were employed at the construction site, although most had gone home for the weekend.
Alfredo Albis, 55, told AFP he was asleep at a barracks for workers about 5m from the structure when it gave way.
“I have two cousins who are still trapped there. They were working here to earn for their families and (they) are missing,” he said, adding “there’s a possibility that my relatives are dead”.
