Here is what was said.

Transurban sought expert opinion from geotechnical engineer John Braybrooke, who said in a report that “the design for the tunnel elements and the tunnel elements themselves are not fit for purpose … and are affected by poor workmanship”.

The alleged faults include “numerous cracks … and in places, the shotcrete is bulging away from the underlying rock or has fallen”.
Braybrooke also alleged “seepage including onto the road pavement, and inadequate drainage and poor workmanship, in that the shotcrete had not been applied to the specified thickness in some areas”.
Transurban claims the shotcrete will need to be replaced, refurbished and significantly maintained.
The multi-million dollar legal battle has quietly been running for five years.

Michael Fraser from Operation Redress told Nine News the civil claim was in the public interest and Transurban, which is an ASX-listed company, should have been up front with users.
“There is concern that if the repairs aren’t done soon enough, it may increase the risk to the public”, he said.
In a statement, Transurban said safety was its “number-one priority”.
“All our assets, including the Lane Cove Tunnel, undergo strict and regular maintenance checks to ensure they are safe for all motorists,” it said.
“The tunnel was not built but was acquired by Transurban three years after opening in 2010.”
Thiess’s parent company, Cimic, would not comment on the court action. John Holland also said it would not comment.
The two companies took civil action of their own after an incident in 2005 when an apartment complex collapsed during excavation of the motorway.
The incident happened when the roof area of a ventilation tunnel caved in, creating a sinkhole and forcing the evacuation of around 50 residents. No one was injured.
In that case, the geotechnical engineer was found to have breached its contractual obligation and was ordered to pay $6.8 million.
A decision on who is to blame and who will pay for the latest legal battle is a long way off, with a date yet to be set for a trial.
