CityGrid Dual Circuit 110kV Underground Cable System Brisbane
Queensland 2006

Client: Olex Cables/Energex


Daly’s Constructions completed this project for Olex Cables / Energex in Brisbane, Queensland. The project was a turnkey design and construction project, 12.5km in length, consisting of a fully conduited system from Carindale to the Charlotte St Substation in Brisbane’s CBD.

Extensive planning and communication to all stakeholders was critical in delivering this project along with detailed traffic management plans and setups. Ironman barriers were used broadly throughout this project in built-up residential and commercial areas, which was a first for Queensland.

The project included three major directional drills, installation of the cable fixed to the Captain Cook Bridge cable gantry and the construction of sixteen joint bays. The majority of cable hauls were 870 metres in length. Specialised plant and equipment was developed for the project including a motorised drum stand mounted on a low loader and custom-built cranage at our depot.
