14 May 2020 – Leading design and construction geotechnical specialist Menard Oceania is expanding its presence to support a steady increase in new projects across Victoria, Tasmania and South Australia.
The company’s innovative ground improvement techniques are playing a vital role in two of Victoria’s landmark infrastructure projects; the $6.7bn West Gate Tunnel Project (WGTP) and the $11bn Metro Tunnel. These projects form part of $107bn investments earmarked for state capital projects in the Victoria Government’s 2019/20 budget[i].
“The construction industry spotlight is firmly on Australia’s southern region with major infrastructure projects from dams to wind farms, tunnels and roading upgrades all underway,” says Dave Raftery, Business Development and Project Manager for the company’s Victoria office. “Menard Oceania was delighted to have been appointed as ground improvement specialists on both the West Gate and Metro Tunnel projects in Victoria.”
Menard was awarded its role on the West Gate Tunnel Project by client, CPBJH JV, to install a grout curtain in two separate locations for the inner and outer portals as well as the TBM retrieval pits, drilling to approximately 35 metres and pumping grout to fill voids in the rock.
“This is a critical part of the ground preparation works to stabilise the ground, enabling the safe retrieval of the tunnel boring machines,” says Mr Raftery.
The tunnel, which is scheduled to open in 2022, will reduce reliance on the West Gate Bridge for commuters travelling between Melbourne’s western suburbs and the CBD. It will also provide an alternative route for vehicles travelling to and from the city’s port.
Notably Australia’s biggest public transport project to date, Melbourne’s Metro Tunnel, includes the construction of twin nine-kilometre rail tunnels between South Kensington station and South Yarra with five new underground stations.
The Cross Yarra Partnership (CYP) consortium appointed Menard to carry out the ground treatment works in five locations and construct a 10-metre-high mass grout block at a depth of between 25 to 35 metres underground, to allow for the safe excavation of the Cross Passages, located in area of poor soils between the two tunnels. To date the ground treatment in the 4 passages located in North Melbourne have been complete on schedule with the excavations between the tunnels to commence in the coming months.
Menard mobilized to the first Metro Tunnel site in early 2019 with the additional teams mobilizing to site throughout 2019 and into 2020. The fourth site was completed in March 2020, with the final section to start in Quarter 3 of 2020.
‘‘The Menard team has displayed their skill and professionalism in what can be considered as one of the most challenging jet grouting projects to have been undertaken in Australia,” explained Mr Raftery. “Successfully installing mass grout blocks at 35 meters below ground level in very difficult and varying ground conditions has been no mean feat, especially considering the need for inclining the drilling to miss underground services and working under live rail tracks. We look forward to starting the final site later this year and showcasing the Menard strength once again.”
Other recent project wins include a permanent anchor project for the Kangaroo Creek Dam upgrade in South Australia and ground improvement works for Granville Harbour Wind Farm in western Tasmania.
Commenting on the firm’s continued growth in Australia’s southern states, Menard Oceania’s Managing Director Philippe Vincent credited the firm’s depth of talent and technical expertise.
“We have a strong team, led by Dave Raftery, that is delivering world-class ground improvement work. Landmark projects like Melbourne’s West Gate and Metro Tunnels are going to make an enormous difference to Melbourne’s transportation footprint and we are extremely proud to be involved.”
Mr Vincent says the company is committed to continued growth in the southern region and believes its work on two of Victoria’s largest projects will generate further opportunities. “There are a number of projects in the pipeline that will benefit from Menard’s understanding of local geotechnical conditions and commitment to delivering innovative, cost effective solutions that are safe and minimise environmental impact.”
