Perth City Link Rail
The $360 million Perth City Link rail project was delivered as an alliance consisting of the Public Transport Authority, John Holland and GHD.
The scope involved sinking a 600-metre section of the Fremantle rail line to reconnect the CBD with Northbridge, the construction of a new pedestrian underpass connecting Perth and Perth Underground stations, and major upgrades to Perth Station.
The project was delivered in a challenging environment, building the new Fremantle rail line tunnel within 1.2 metres of the existing Joondalup Line rail tunnels.
Several key factors were critical to project success, including installing a comprehensive dewatering system, constant monitoring of nearby heritage-listed structures and existing rail infrastructure, a combination of different piling techniques to build strong foundations for future above-ground buildings, and a well implemented community relations plan.
The project was successfully delivered six months ahead of schedule and on budget.
