SOUTH AFRICAN Department of Labour officials are scrutinising two expert reports into the cause of the Injaka bridge collapse which killed 14 people last year (NCE 16 July).
The reports, submitted on Friday to the official inquiry into the disaster, are the first pieces of technical evidence produced by the bridge's designer VKE and main contractor Concor Construction in the 10 months since the accident.
Department of Labour officials submitted their own report eight months ago.
The reports will remain confidential until they are presented to the inquiry in July. They will then be used in conjunction with expert witnesses from VKE, Concor and the DoL to establish the cause of the failure.
VKE and Concor have already agreed the sequence of the collapse. Both claim it was triggered by the lower flange of the incrementally launched prestressed concrete deck failing at an intermediate support (NCE 21 January).
