WESTCONNEX M4 VENT FACILITY & ROZELLE INTERCHANGE

A productive cranage solution for a deep & congested excavation

MAJOR INFRASTRUCTURE

AUSTRALIA

PROJECT OVERVIEW

WestConnex is Australia’s biggest integrated transport and urban revitalisation project. A joint project by the Australian Government and NSW State Government, the 33-kilometre predominantly underground motorway scheme includes around 26 kilometres of new tunnels passing underneath Sydney’s Inner West.

Our client sought a cranage solution to speed up the removal of spoil and movement of heavy equipment during the construction of ventilation shafts on what was a deep and congested excavation site.

THE CHALLENGE

From an engineering point-of-view, this project was logistically difficult due to:

A deep excavation site, with limits on loads that could be applied adjacent to the excavation
Location – in a high-traffic zone flanked by three main arterial roads
Congestion – limited space and lay-down area
Schedule – demanding construction program

OUR SOLUTION

Marr’s solution – with the combination of high-speed, high-capacity winches and long reach – provided the ability to remove 400 per cent more spoil compared to previously available approaches.

Once excavation works were completed, Marr’s cranes supported the heavy lifting requirements associated with construction of the ventilation facility.

THE RESULT

Benefits of early engagement with Marr included:

Small footprint – opportunity for utilisation of additional lay-down areas on-site
Speed of excavation and spoil removal
Flexibility and versatility to be able to use cranes for the installation of plant equipment and structures during excavation works, without demobilising and remobilising cranes
Capability to lift heavy equipment including excavators in and out of the construction site.
