Aurora Carisbrook Substation

Octa was asked to provide project management services for the new Carisbrook substation build alongside the 11Kv & 33Kv cables upgrade, to ensure safe and reliable power with capacity to expand.

Along with heavy media coverage, the challenges included the need to remove 14,000 poles and redundant overhead lines, communicate with over 60 stakeholders affected by trenching works, trenching through some of the city’s busiest roads, working with eight separate contracts, and a very tight 18-month programme.

Trenching and civil work began in July 2017 for the 2 kms of underground cabling from the South Dunedin grid exit point to the Carisbrook substation.  Construction began on the substation in September 2017 with commissioning programmed for November 2018.

The project was entered into the Otago CCNZ Construction Awards and won the over $1M category.  Downer’s Otago Construction Manager considered it to be a Project Team achievement and commented:

…” The success of a project is not just up to the Contractor but is highly influenced by the experience and behaviour of the client- side representatives.   I felt that for this contract you (Octa) provided clear vision on what was important to the client, while also enabling the flexibility for us to have robust open discussions around methodology and contract commercials. 

Tony Clough went on to say “…the judges acknowledged the fact it was really well delivered with good project management principals implemented from start to finish…’
