Durban - Workers building the Tongaat mall may have been using the design engineer's old drawings, the commission of inquiry investigating the structure's collapse heard on Wednesday.
This emerged during a dispute between Richard Hoal, for engineer Andre Ballack, and Jay Singh, the chief executive of Gralio Precast, the company that built the mall.
The commission is investigating the mall's collapse on 19 November 2013, in which two workers were killed and 29 injured. Construction started in May that year.
