Project Description

The site has been backfilled over the years and the spoil has been replaced with Terefil 500 – a lightweight concrete grout. This was then covered with a bentonite waterproofing blanket and sealed with site concrete.

This soil improvement system is the result of a collaboration between Vector and Watercare to future proof Watercare’s upcoming North West interceptor project which is planned to run through Vector’s site. 

The site has been challenging with up to four metre deep excavations in weak soils. In addition, existing fibre optic cables were located running through the main building footprint.

To help the substation blend in with surrounding homes, the walls of the new switch room include some architectural panels that show a weatherboard effect.

The contract period for this project is expected to be eight months.

Technical Overview

The new substation in Hobsonville Point is set amongst new urban housing development and is Connells first project with Vector as the main contractor.
