Investigations into the collapse of a partially completed office block have been put on hold until a worker believed to be trapped under the rubble is found, the labour department said on Friday.
Spokesperson Page Boikanyo said preliminary investigations had been done into the collapse of the building.
A notice was served to the contractors to stop building on the site until the department's investigations were completed.
The preliminary probe would be followed by a detailed investigation after the missing worker was found.
Civilian and departmental experts would be asked to assist in the investigations, Boikanyo said.
Departmental building inspectors inspected the site on Thursday and served the notice to stop building to the contractors for the entire site.
Honeydew police Inspector Karen Jacobs said attempts to rescue the trapped worker had halted around 10am because the area where sniffer dogs had reacted and rescuers were working had started to collapse.
The rubble was loose and earth-moving equipment was being used to dig it out from one side.
Labour Minister Membathisi Mdladlana was on site, Jacobs said.
