Sydney Metro Northwest (Tunnels and Civil Works)

Working with CPB Contractors

Project: Sydney Metro Northwest (Tunnels and Civil Works)

Challenge 

Tunnel Boring Machine (TBM) removal at Epping

Solution 

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.
