The Tunnels design team is a relatively new addition to CIMIC Group’s EIC Activities, but it’s already kicking some important goals.
Transport for NSW M6 Stage 1 - Sydney
Recently, an alternative concept design for the Bicentennial Park tunnel access shaft for the Transport for NSW M6 Stage 1 provided a significant cost saving and de-risked the program.
The images below show the original design and the new design which reduced the risk of the program by removing the ground anchors which would have been a time-consuming process to install and test.
A comprehensive 3D modelling was used to verify the new binocular shaft design would work.
The Transport for NSW M6 Stage 1 will deliver the missing link from Sydney’s south to the wider Sydney motorway network making journeys easier, faster and safer. The main works consist of a twin four-kilometre tunnel linking the M8 Motorway at Arncliffe to President Avenue at Kogarah. The project was awarded to the CPB, Ghella and UGL (CBPGU) JV.
