Director of Fire and Emergency Services Ashok Menon said that the rescue operations stood withdrawn from 3 pm onwards.
"The total number of casualties in the building collapse has gone up to 31," he said.
The operation was stopped after authorities certified there are no more dead bodies under the debris of the five-storey under construction building that had caved in on January 4.
Over 40 workers were present at the site when the mishap occurred.
The rescue teams which pulled out 16 people alive had suspended their operation earlier after two adjacent buildings near the spot tilted.
The State police have so far arrested two government officials, including a deputy collector, in connection with the incident, whereas the builder and contractor of the project are still untraceable.
