Those still under the 35-metre pile of fallen gravel include a Malaysian, while the 13 others, including the three found deceased, were Indonesians, Bangladeshis and Rohingyas.
The identities of the three men pulled out from the rubble have yet to be ascertained.
Earlier reports that two people had been rescued were inaccurate as sources at the site had mistaken a number of people who were injured near the landslide as having been buried under it as well.
Penang Fire and Rescue Services Department director Saadon Mokhtar said three dogs from the K-9 unit had been deployed to search for the victims.
He said the effort to rescue the remaining 11 people would take time as the landslide covering an area of 160 square metres was at least 35 metres deep.
“We are facing a problem clearing the large swathes of earth. So we have divided them into sections of 15 square metres and are methodically removing the earth little by little.
“A portion of a basement level of the car park under construction has also collapsed.
“So we need more time to excavate the area,” Saadon told reporters at the site here today.
In the 8.50am incident, a 10m-high hillslope came crashing down at the construction site of a condominium, near the Tunku Abdul Rahman College (TARC) in Tanjung Bungah.
The sole Malaysian victim in the incident was a site supervisor who happened to be a TARC graduate.
The affordable housing condominium being developed by a private company was slated to be completed by June 2020, with two 49-storey towers containing a total of 980 units.
The construction appears to have been in the early phase, with just the first two storeys of the condominium’s 12-level car park already built.
