Investment in CBD plant helps secure contract

Auckland’s new Victoria Park Tunnel (VPT) aims to ease the congestion for more than 100,000 commuters using the viaduct each day. The 460m, three-lane, one-way northbound tunnel will be constructed using a ‘cut and cover’ method utilised by Fletcher Construction on the New Lynn Rail Trench.

Firth were awarded an initial contract of approximately 2,000m3 earlier in the year and have also recently gained the largest portion of the contract to supply the main tunnel structure concrete - in excess of 30,000m3. The pressure is on the VPT alliance team members to deliver the project with an ambitious target of completion for the start of the RWC2011.

Strategic and safe

Firth's improved Hamer Street plant now resides 300m north of the old site - just a few hundred metres from the VPT workzone.

The revamped site has been a key contributor in securing this very large contract for Firth. The new plant sits on nearly twice as much land as the old plant, which meant Firth was able to redesign the plant to improve traffic flow, safety and efficiency. Firth is the only concrete company with the ability to batch concrete in the Auckland CBD, making the relocation and redesign of Hamer Street essential for Firth to be able to offer customers prompt, reliable concrete supply in the heart of Auckland City.
