Road Bridging – Wellington & Picton Rail Yard

Sector: Airports & Ports

Client: KiwiRail

Date: 2015

Project Location: Wellington

Frequency Role: Project Manager and Engineer to the Contract

KiwiRail has as a result of the decommissioning of the Interislander Arahura ferry and the lease of the Kaiarahi changed it operational requirements for transferring freight a cross the Cook Strait.

With the new ferry not being rail capable, rail wagons previously transported between Picton and Wellington now need to be transferred from the rail wagons to road trailers.

This prompted the development of new infrastructure both at Wellington and Picton rail yard to enable Road Bridging to take place.

The scope of works was to construct a container transfer site in Picton together with trailer staging area. In Wellington an internal haulage road was constructed to enable KiwiRail to move freight internally to avoid using public roads. The ferry terminal area was enlarged through removal of the Arahura rail tracks. This created a large trailer staging area to minimize the impact on the passenger and commercial vehicle check in and staging area.

The operational plans for the Wellington rail yard needed to be altered to accommodate for the new haulage road to ensure that operational there are no conflicts between train movements and trailer movements along a route that has 6 level crossings.

Frequency’s role on the project was programme manager for all work-streams, Project Manager of the various individual work-streams and acting as the Engineer to the Contract under the NZS3910:2013 contract. This involved managing the design team and stakeholders through the initiation, design and execution of the works.

Key Challenges:

  • Working in an operational environment where train shunting & ferry terminal activities were ongoing through the construction site.
  • Significant logistical and detailed construction methodology combined with intricate pre-planning to ensure works completed on time.
  • Multiple stakeholder liaisons, particularly with KiwiRail and Interislander Operations team.
  • Challenging timeframe to meet operational requirements.
  • Managing several work-streams to tight budgets.
