Scope of Works

Design, supply, fabrication, transportation, site installation, testing, commissioning and close-out for the expansion of the Christmas Creek Chichester Power Network.

Power station works including the installation of a 10MVA step up transformer, 33kV RMU and associated civil work.
Overhead line works including 33kV power line to the Remote Crushing Hub and the new Central Contractors Yard.

11kV underground supply to the new Ore Processing Facility: 22,000m of 11kV underground cable laid via 8 circuits in trefoil formation.

Construction Planning:

Tight timeframes forced Contraflow to think outside the box and procure cable and cable laying equipment direct from an international manufacturer to save time.

Contraflow utilized a fir tree construction to minimise steel work requirements which allowed the company to complete all works on time and within budget.

Variations to the original design included route changes, extra procurement items and increased civil construction scope.
