NSW Government Takes Decisive Action on M6 Tunnel Stalemate
The New South Wales government has escalated its dispute with contractor CGU by issuing a formal 'notice of default', compelling the consortium to resume work on the stalled M6 tunnel in Sydney's south or face potential legal repercussions. This move comes after more than two years of delays, primarily due to large sinkholes and a challenging geological feature discovered during construction.
Contractor Ordered to Recommence Work by May 1
NSW Roads Minister Jenny Aitchison announced that CGU, a joint venture comprising CPB, Ghella, and UGL, has been directed to restart excavation on the 90% complete twin tunnels by May 1. The project, which aims to connect Sydney's south to the broader motorway network, has been on hold since March 2024 when sinkholes emerged, followed by the identification of a 'high-angle reverse fault' in the bedrock last June.
Minister Aitchison emphasised that the government has presented an engineering solution within the existing contract framework, stating, 'Transport for NSW has issued a notice of default to CGU after more than two years of work to try to resolve the issues affecting this project.' She added that it is a reasonable community expectation for the contractor to deliver on its commitments.
Premier Minns Rules Out Additional Funding
NSW Premier Chris Minns has firmly rejected any possibility of providing extra funds to cover the estimated $1.5 billion required to address the tunnel's challenges. He criticised CGU's unilateral decision to halt work, asserting that the contractor assumed risks in design and construction. 'I'm sorry it hasn't worked out but, at the end of the day, they have to make good on it,' Minns told reporters, highlighting that CGU is a large international infrastructure company bound by its agreement with the government.
During NSW transport estimates, Minister Aitchison confirmed that CGU has not formally requested additional funding, though the company expressed concerns about delivering the project safely and viably. She noted that ongoing legal negotiations prevent disclosure of potential extra costs or a revised completion date, but assured that the government is holding the contractor accountable.
Project Delays and Legal Costs Mount
Originally approved in 2019 with an opening scheduled for 2025, the M6 tunnel's completion has been postponed to 2028 due to the sinkholes and geological fault. The 4km tunnels, part of a $3.1 billion motorway initiative, have faced significant setbacks, with excavation grinding to a halt last year after CGU claimed a design solution was unachievable.
The dispute has already incurred $5 million in legal fees for the NSW government, as revealed in committee hearings. When questioned by Nationals MLC Nichole Overall about the risk of the project becoming a 'white elephant', Minister Aitchison declined to comment further, citing legal sensitivities and accusing the opposition of scaremongering.
In summary, the NSW government is taking a firm stance to ensure the M6 tunnel's completion, leveraging contractual obligations to push CGU forward despite geological hurdles and financial uncertainties.
