Largest Brownfield Trenchless Relocation in Australia

(Aziz) Jiang Aizezi

Thornlie Cockburn Link (TCL) project consists of a new railway line between the Armadale and Mandurah lines via the Thornlie and Cockburn Stations. The track extension from Thornlie to Cockburn is approximately 14.50 km.

To make way for the major construction works, a 12.6km of existing BP KWOL (Kewdale White Oil Line) required to be relocated which is situated within the narrow brownfield railway corridor.  The works consists of 11.5km of Horizontal Directional Drilling (HDD), two 50m microtunnelling/pipejacking crossing operational PTA passenger and Arc freight rail, 1km of open trench, 120m steel truss river crossing, 2 pigging stations and 12 valves and associated valve pits.

This presentation will dive into how the determined team have overcome several design and construction challenges and safely delivered the project, these includes:
