Our challenge working on the Sydney Metro Northwest (Tunnels and Civil Works) project was how to safely remove the Tunel Boring Machine at Epping for CPB Contractors.
EIC Activities’ methodology used a 500t mobile crane and a steel cradle with a pin connection to move the 700t TBM 50m across the station box floor and rotate it 50 degrees.
The move was completed in one shift, eliminating the costs of a second crane and a piled crane foundation and avoided scrapping the TBM.
