Clarke Underground has the capability to complete large scale projects.

Examples are included below.

NICE 4

In 2018 Clarke Underground successfully completed an extensive project commissioned by KiwiRail. The North Island Communication enhancement – stage 4 (NICE 4).

The project involved 326km of duct installation within the KiwiRail corridor, ideally 5-7m from the rail centre line, along the main trunk line from Porewa to Te Awamutu. Of the 326km Clarke Underground were responsible for the majority of installation, that being the 210km from Porewa through to Te Kuiti.

The project required mole-ploughing, open trenching, directional drilling and rock sawing. The main methodology used for the project was to clear existing vegetation, pre-rip the area with a large digger in preparation for the ploughing. After the ploughing, installation of ducting occurred then the area was tidied and compacted with tractors and diggers.

The 22-million-dollar project took 2.5 years and will allow the installation of fibre connectivity for KiwiRail operational systems.
