SYDNEY, Australia – 18 October 2018 – Leading design and construction geotechnical specialist Menard Oceania has been awarded the treatment and preparation work for ground works in Sydney Metro City & Southwest station sites, Barangaroo and Waterloo.
At the Barangaroo Station site, Menard Oceania will utilise Jet Grout and Rock-mass Permeation Grouting Techniques to cut-off groundwater flow ahead of excavation of the station box. Works at the Waterloo Station site comprise of more than 1,000 anchors and rock bolts that provide lateral support for the station box excavation.
Working on behalf of the tunnel and station excavation contractor, JHCPBG (John Holland, CPB, Ghella), Philippe Vincent, Managing Director, Menard Oceania said;
“Sydney’s geology is well known as being one of the world’s best stratum for tunneling. With over 45 years of experience in the city, we understand local geotechnical conditions and use innovative and cost-effective techniques to re-engineer poor soils and weak rock formations into solid foundations.
“This award further reinforces Menard as a dominant player in Australia on complex infrastructure projects,” he added.
The geology at both station sites consists of fill, sand and residual soils, marine sediments and deep alluvial soils; as well as a challenging high groundwater table.
Sydney Metro City & Southwest extends the new metro network from the end of Sydney Metro Northwest at Chatswood, under Sydney Harbour, through the CBD, and west to Bankstown.
JHCPBG is building the 15.5 kilometre long twin railway tunnels between Chatswood and Sydenham and excavating six new metro stations.
