Norwest Pedestrian Tunnel

Client

CPB/John Holland

Year

2016-2017

Location

Sydney, Australia

The Norwest Pedestrian Link connected the New Sydney Metro Norwest Station with the Norwest shopping precinct via a tunnel under Norwest Boulevard.

The Lump Sum project consisted of escalator ramp and shaft excavation with shotcrete support. The tunnel consisted of 38m long canopy tubes, tunnel excavation and a water proof layer followed by a permanent shotcrete lining.

With this project came the complex task of de-stressing  some previously installed cable anchors. Tunnelling Solutions innovation, which comes from years of experience, developed a small timber heading hand driven tunnel to reach the position of the cable anchors. This was completed very successfully and was a big HIT with our client.
