Chief Minister Manohar Parrikar said all the authorities had certified that there was no possibility of finding any more survivors in the debris of the collapsed building.
The building caved-in as its design was faulty and the quality of construction was poor, Parrikar said, adding that the structure that collapsed, as well as the ones adjacent to it, had been built on a weak foundation.
The three buildings in question have been declared as being unsafe structures and would be demolished within a span of four days, he said.
Goa government had yesterday withdrawn rescue operations at the site of the building collapse in Cancona town, about 70km from here, after two of the adjacent buildings began to tilt precariously.
Police registered an FIR against several persons, including government officers, who had allegedly cleared the controversial five-storey project of 80 flats.
