FIBRE LINK INSTALLATION - MANAPOURI TO BLACKMOUNT 

Client: Downer / Chorus

Location: Manapouri to Blackmount

Service: Optic Fibre Link Installation

 

Date started: December 2022

Date completed: March 2023

Challenges

Communication on site is very limited and all materials have to come from Te Anau or Invercargill.

In addition to this, the weather in this area is some of New Zealand's worst both in terms of rainfall and temperatures.

Solutions

Marais Laying NZ proposed using its experienced team from other long backbone projects.

The project has been divided into 2 sections (north and south) to make it faster to build.

Our team focused on the mole plough followed by trenching and drilling around bridges and obstacles.

Result

Marais Laying NZ has been installing up to 1200m of new duct per day, finishing the project ahead of schedule.
