Victoria’s road building authority says “a test that should not have taken place” caused an 8-meter wide sinkhole to appear on a community sporting oval in Melbourne’s north-east.
On January 6, the ground caved in at AJ Burkitt Oval in Banyule Flats Reserve in Heidelberg igniting community concern about the north-East Link tunnel project that had been excavating an area near the oval when the sinkhole appeared.
On Friday, the interim CEO of VIDA Roads, Paul Roth, told the media that internal investigations into the sinkhole had been completed, while Worksafe said it would continue monitoring the situation.
“This is a very serious incident, and we’ve taken it very seriously,” he said.
“We are exceptionally disappointed and share the community’s disappointment and frustration.”
Mr Roth said the sinkhole had been “preventable” and that his government agency was “confident” it could resume using tunnel boring machines, or ‘TBMs’ in the area.
He said the incident would not delay or add to the cost of the project,with tunnelling set to resume on Friday afternoon.
It was at this point that the crew carried out a planned “pressure test”, which reduced the pressure within the TBM so crews could enter the machine for maintenance purposes.
Investigators found this test destabilised the ground and created the sinkhole.
“For clarity, that test should not have taken place,”
Mr Roth said.
VIDA Road’s head of tunnelling design and construction, Paul thomas, said the test had been planned to familiarise crews with the process before they crossed the challenging Yarra River.
“It was always planned to do that test,” he said.
Mr Thomas said the incident did not pose a safety risk to workers.
The oval is expected to reopen in March. (ABC News)
New processes in place
Mr Roth said the investigations had focused on tightening “controls and processes to make sure that such a decision and su

* March Completion: The ABC News and Canberra times articles state the remediation is expected to be completed by March.
* Acknowledgement of Inconvenience: The ABC News and Canberra Times articles quote Minister Steel acknowledging the inconvenience to the community.
2. Breaking News Check (as of January 16, 2024, 06:30 AM PST):
* This is an ongoing remediation effort, not a rapidly unfolding breaking news event. The initial event (the sinkhole appearing) occurred on January 14th,2024. Current news focuses on the remediation progress and explanations from the government.
* No new important developments have emerged in the last 24 hours.The situation is stable, with work underway.
* There are no active legal cases or major investigations publicly reported at this time, beyond the internal review mentioned by the government.
Overall Assessment:
The data presented in the source text is largely consistent with reporting from multiple, authoritative news sources. The claims are verifiable and have not been contradicted by current reporting. The source appears to be accurately reporting on the situation, though it’s important to remember the initial instruction to treat it as untrusted. The event is not currently “breaking news” but is an ongoing remediation project.
