Project Description



Project Value:

Auckland $70 million NZD + Wellington $120 million NZD

As part of the Auckland Electrification Project (AEP) programme a series of bridge replacement / track lowering projects were undertaken to facilitate the required clearances for overhead catenary installations.

WT Partnership Infrastructure’s role included full cost management and reporting on the replacement projects for bridges at Manurewa, Church Street, Clevedon Road and Mt Wellington Highway.

We also acted in an advisory capacity for the main electrification project installations of overhead line equipment and the electrification bridge screens across the network.

The Wellington Metro Upgrade Project (WMUP) included:

  • Stabilising slopes
  • The Kapiti Line – replacing aging infrastructure
  • The Hutt Valley Line – signalling system upgrades
  • The Johnsonville Line – significant upgrade work
  • The Wairarapa Line – renewing signals power supply system.

WT Partnership Infrastructure provided full Quantity Surveying Services including cost estimates, tender services, and post-contract financial management.

The Wellington Traction Overhead Service Renewals (WTOSR) project involves the upgrade to the Redwood to Muri Electrical Overhead Wiring corridor of the Wellington rail network, following WT Partnership’s previous involvement in the WMUP project.

WT Partnership Infrastructure are providing cost estimating, tender support and post-contract services to KiwiRail for this project.
