LEGAL NEWS
A massive class action case involving over 150 businesses in Queensland and New South Wales suing a Queensland Government entity has evolved with a third party being lassoed into the lawsuit as a defendant, having 76,573 documents dumped in their laps in three weeks only eight months before the trial starts.
The plaintiffs claim works carried out by the corporation in the Gladstone Harbour negatively impacted the water quality, fish health and fish numbers, impacting industry members’ businesses.
The plaintiffs says that there are defects in the construction of the bund and they attempt to enumerate dozens of more breaches of particular types of contract.
Barrister Mark Steele KC said there were thousands of documents to read through and they need to find out who was responsible for geotextile covering and other parts of the construction of the bund wall as part of their defence.
Engineers involved in the investigation, design and construction of earthworks, especially where geosynthetic materials are involved, can learn from historical precedent – particularly when such structures have failed.
The case of the failure of the Gladstone Harbour bund wall has brought to light numerous recommendations for the future construction of such coastal earthworks, after an independent review into the wall was commissioned last year.
The Port of Gladstone Western Basin Strategic Dredging and Disposal Project (WBSDDP) allowed for a maximum of 46 million m³ of dredge spoil to be removed and disposed of, both offshore and within a constructed reclamation area.
The bund wall surrounding the reclamation area began leaking and coincided with mass deaths and disease of marine life in the nearby Great Barrier Reef World Heritage Area. Engineers claim that the geotextile fabric was of the wrong type and had been incorrectly fitted in the construction of the wall, were subsequently leaked to media outlets, prompting closer scrutiny.
Federal environment minister Greg Hunt commissioned the Gladstone Bund Wall Independent Review panel to examine and report on information relevant to the design, construction and functioning of the outer bund wall of the WBSDDP and to consider the adequacy of monitoring requirements. The panel found that aspects of the design and construction of the bund wall were not consistent with industry best practice and there was inadequate restraint of the geotextile liner. One of the key elements of the final design was the screening of the core rock to remove material of less than 12 mm diameter and the placement of a geotextile liner on the internal face of the bund wall. The bund design included the placement of geotextile fabric on the inner face of the bund before commencement of filling operations. This was meant act to minimise the migration of fines through the bund wall and into the surrounding waters from the differential pressures created on either side of the wall by the rise and fall of the tide.
