Integrated Vector and Chorus Civil Infrastructure Upgrade

Auckland | HV and LV Network Civil Works | Telecommunications Civil Works

Civilink NZ delivered an integrated civil package supporting a major Vector electricity network upgrade and the coordinated undergrounding of Chorus telecommunications infrastructure. The works provided civil readiness for a new 11 kV switch, a 300 kVA ground-mounted transformer, HV jointing, LV service infrastructure and separate Chorus ducting.

Working within an active public road corridor, the team coordinated service locating, traffic management, staged excavation, HV and LV duct installation, Chorus duct installation, equipment foundations, joint-bay access, backfilling, reinstatement and as-built documentation. Each utility system was maintained as a clearly identified and independently compliant workstream.

Separate green Chorus ducts installed beside the electrical civil corridor

Two 150 mm HDPE HV ducts plus dedicated HV and LV routes
Separate Chorus telecommunications duct system

Coordinated road-corridor access, reinstatement and as-built handover

Project Outcome

The completed civil infrastructure created compliant, clearly separated pathways for both electricity and telecommunications assets, allowing Vector and Chorus to undertake their respective specialist cable, connection, testing and commissioning activities.
